    Individuals with metabolic syndrome are at increased risk for developing cardiovascular disease and diabetes mellitus. This study was carried out to determine the prevalence of metabolic syndrome and clinical characteristics in hypertensive patients according to the criteria of the new International Diabetes Federation (IDF) definition. Hypertensive patients were recruited from the Medical Out-Patient Department, Kuantan Hospital. The five components of metabolic syndrome were examined which included blood pressure (≥130/85 mmHg), fasting glucose (≥5.6mmol/L), fasting triglycerides (≥1.7 mmol/L), high-density lipoprotein (HDL) cholesterol level (80cm). Out of 139 hypertensive patients, there were 113 met all the selection criteria consisted of 61 male and 52 female subjects. The participants’ age ranged from 21 to 91 years (51.9±16.8 years; mean±SD), and body mass index 13.5-42.3 kg/m2 (27.5±4.9 kg/m2). According to the IDF criteria, the prevalence of central obesity was 67.2% in men and 84.6% in women. Among the 113 hypertensive subjects over 21 years of age, 51 subjects or 45.1% had metabolic syndrome. The present data revealed that there was high prevalence of metabolic syndrome in Malaysian hypertensive subjects. This finding was supported by the fact of high prevalence of central obesity among the study subjects.

    OBJECTIVE: To investigate the long-term effects of Tualang Honey versus Honey Cocktail (mixture of honey, bee bread, and royal jelly) on cardiovascular markers and anthropometric measurements of postmenopausal women.

    METHODS: We conducted a randomised, double blinded, two-armed parallel study comparing 20 g/day of Tualang Honey versus 20 g/day Honey Cocktail among postmenopausal women aged 45-65 years. The cardiovascular parameters and anthropometrics measurements were assessed at baseline, 6 months, and 12 months of the intervention.

    RESULTS: 100 subjects were successfully randomised into the groups. There was a significant decrease in the diastolic blood pressure from 77.92 mmHg at baseline to 73.45 mmHg at 12 months (F-statistic = 2.55, p-value = 0.047) in the Tualang Honey group compared to Honey Cocktail. There was also a significant decrease in the fasting blood sugar from 6.11 mmol/L at baseline to 5.71 mmol/L at 12 months (F-statistic = 4.03, p-value = 0.021) in the Tualang Honey group compared to the Honey Cocktail group. The body mass index remained unchanged at 27 kg/m2 (F-statistic = 1.60, p-value = 0.010) throughout 12 months of the intervention in the Honey Cocktail group.

    CONCLUSION: Subjects who received Honey Cocktail showed remarkable effects on body mass index. However, Tualang Honey supplementation showed superior effect in lowering diastolic blood pressure and fasting blood sugar compared to Honey Cocktail. Further studies are required to ascertain the underlying mechanism(s) of Tualang Honey and Honey Cocktail on each observed parameter.

    It is known that BK does play a role in the cardioprotective effect of angiotensin converting enzyme (ACE) inhibitors. The present study therefore was conducted to examine the effects of bradykinin (BK) and its antagonist on survival time in spontaneously hypertensive rats (SHR) with coronary artery ligation for 15 min and continuously. We also evaluated the heart rate and blood pressure (BP) in the presence and absence of BK and BK2 receptor antagonist, D-Arg-[Hyp-D-Phe7]BK. Coronary artery was ligated in anaesthetized rats and they were artificially ventilated with room air (stroke volume, 4 ml; 48 strokes/min) as described by the previous investigators. Lead II elecrocardiogram (ECG) was recorded from subcutaneous steel needle electrodes. Results of this investigation indicated that BK treatment 4 microg/kg (i.v.) and 8 microg/kg (i.v.) caused significant (P < 0.05) increase in survival time in SHR with coronary artery ligation for 15 min and continuously as compare to their respective saline-treated controls. However, BK antagonist treatment 4 microg/kg (i.v.) abolished the increase in survival time caused by BK treatment. The mean values of survival time between the saline-treated and BK antagonist plus BK-treated rats did not differ significantly (P > 0.05). The heart rate and BP responses were greatly reduced (P < 0.001) in the presence of coronary artery ligation. These findings suggest that BK might have cardioprotective effect to increase the survival time in rats by activating BK2 receptors after coronary artery ligation.

    OBJECTIVE: To compare the efficacy of dexmedetomidine versus morphine as a sedative/analgesic among post-operative cardiac surgery patients.

    METHOD: A randomized controlled open-label study was performed at the cardiothoracic intensive care unit of Penang Hospital, Malaysia. A total of 28 patients who underwent cardiac surgeries were randomly assigned to receive either dexmedetomidine or morphine. Both groups were similar in terms of preoperative baseline characteristics. Efficacy measures included sedation scores and pain intensity and requirements for additional sedative/analgesic. Mean heart rate and arterial blood pressure were used as safety measures. Other measures were additional inotropes, extubation time and other concurrent medications.

    RESULTS: The mean dose of dexmedetomidine infused was 0.12 [SD 0.03] μg kg⁻¹ h⁻¹, while that of morphine was 13.2 [SD 5.84] μg kg⁻¹ h⁻¹. Dexmedetomidine group showed more benefits in sedation and pain levels, additional sedative/analgesic requirements, and extubation time. No significant differences between the two groups for the outcome measures, except heart rate, which was significantly lower in the dexmedetomidine group.

    CONCLUSION: This preliminary study suggests that dexmedetomidine was at least comparable to morphine in terms of efficacy and safety among cardiac surgery patients. Further studies with larger samples are recommended in order to determine the significant effects of the outcome measures.

    This is a randomized, double-blind, placebo-controlled study comparing the effects of a water extract of Labisia pumila var. alata at 280 mg/day with placebo, given for 6 months in postmenopausal Malay women. There were 29 patients treated with Labisia pumila and 34 patients in the placebo group. Menopausal symptoms were assessed at baseline and at 6 months. The blood pressure, body mass index, waist circumference, fasting blood sugar, lipid profile, and hormonal profile (follicle stimulating hormone/luteinizing hormone/estradiol) were measured during visits every two months. ANCOVA model analysis showed significantly lower triglycerides levels in LP subjects at 6 months after treatment as compared to placebo (1.4 versus 1.9 mmol/L; adj. mean difference 0.5, 95% CI: 0.02, 0.89 after adjusted for the baseline values, age, BMI, and duration of menopause placebo). Other parameters in both groups did not differ significantly. In conclusion, daily intake of Labisia pumila at 280 mg/day for six months was found to provide benefit in reducing the triglyceride (TG) values.

    Hypertension incurs a significant healthcare burden in Asia-Pacific countries, which have suboptimal rates of blood pressure (BP) treatment and control. A consensus meeting of hypertension experts from the Asia-Pacific region convened in Hanoi, Vietnam, in April 2013. The principal objectives were to discuss the growing problem of hypertension in the Asia-Pacific region, and to develop consensus recommendations to promote standards of care across the region. A particular focus was recommendations for combination therapy, since it is known that most patients with hypertension will require two or more antihypertensive drugs to achieve BP control, and also that combinations of drugs with complementary mechanisms of action achieve BP targets more effectively than monotherapy. The expert panel reviewed guidelines for hypertension management from the USA and Europe, as well as individual Asia-Pacific countries, and devised a treatment matrix/guide, in which they propose the preferred combination therapy regimens for patients with hypertension, both with and without compelling indications. This report summarizes key recommendations from the group, including recommended antihypertensive combinations for specific patient populations. These strategies generally entail initiating therapy with free drug combinations, starting with the lowest available dosage, followed by treatment with single-pill combinations once the BP target has been achieved. A single reference for the whole Asia-Pacific region may contribute to increased consistency of treatment and greater proportions of patients achieving BP control, and hence reducing hypertension-related morbidity and mortality.

    BACKGROUND: Hypertension is one of the world's most common health conditions and is a leading risk factor for mortality. Although blood pressure can be modified, there is a large proportion of patients whose blood pressure remains uncontrolled. The aim of this study, termed Edvantage 360°, was to gain a deeper understanding of hypertension management in Asia from the perspective of patients and doctors, and to propose strategies to improve blood pressure control.
    METHODS: Conducted in Hong Kong, Indonesia, Malaysia, the Philippines, South Korea, Taiwan, and Thailand, Edvantage 360° was a mixed-methods observational study that used both qualitative and quantitative elements: qualitative interviews and focus groups with patients (N = 110), quantitative interviews with patients (N = 709), and qualitative interviews with doctors (N = 85).
    RESULTS: This study found that, although there is good understanding of the causes and consequences of hypertension among Asian patients, there is a lack of urgency to control blood pressure. Doctors and patients have different expectations of each other and a divergent view on what constitutes successful hypertension management. We also identified a fundamental gap between the beliefs of doctors and patients as to who should be most responsible for the patients' hypertension management. In addition, because patients find it difficult to comply with lifestyle modifications (often because of a decreased understanding of the changes required), adherence to medication regimens may be less of a limiting factor than doctors believe.
    CONCLUSIONS: Doctors may provide better care by aligning with their patients on a common understanding of successful hypertension management. Doctors may also find it helpful to provide a more personalized explanation of any needed lifestyle modifications. The willingness of the doctor to adjust their patient interaction style to form a 'doctor-patient team' is important. In addition, we recommend that doctors should not attribute ineffectiveness of the treatment plan to patient non-adherence to medications, but rather adjust the medication regimen as needed.

    1 Interaction between renin-angiotensin (RAS) and sympathetic nervous systems (SNS) was investigated by examining the effect of cumulative blockade of angiotensin II (Ang II) and adrenergic receptors in normal Sprague Dawley rats. 2 Rats were treated with losartan (10 mg/kg), carvedilol (5 mg/kg), or losartan plus carvedilol (10+5 mg/kg) orally for 7 days. On day 8, the animals were anaesthetized with pentobarbitone and prepared for systemic haemodynamic study. Dose-response relationships for the elevation of mean arterial pressure or change in heart rate (HR) in response to intravenous injections of noradrenaline (NA), phenylephrine (PE), methoxamine (ME) and Ang II were determined. 3 Losartan or the combination of losartan with carvedilol blunted vasopressor responses to ME and Ang II. Dose-response relationships for agonist action on HR were significantly inhibited by all treatments except for the combination of losartan and carvedilol on the decrease in HR induced by PE. Carvedilol decreased vasopressor responses to NA, PE and Ang II, and HR responses to NA, ME and Ang II. Combination treatment produced similar effects to losartan on the vasopressor and HR responses but had a greater effect on vasopressor responses to ME and Ang II, and on HR responses to NA and Ang II than carvedilol alone. 4 It is concluded that peripheral vasoconstriction induced by Ang II is partly mediated by adrenergic action and that the vasopressor responses to adrenergic agonists depend on an intact RAS. These observations suggest an interactive relationship between RAS and SNS in determining systemic haemodynamic responses in 'normal' rats.

    This study set out to investigate the impact of chronic cumulative blockade of angiotensin II and adrenoceptors in WKY and SHR and to explore how the renovascular responses to adrenergic and angiotensin II receptor agonists may be interdependent. Rats were treated with either losartan, carvedilol or losartan+carvedilol for 7 days and on day eight, animals were pentobarbitone anaesthetized and prepared for renal haemodynamic study. Dose-response relationships were determined in terms of reduction/elevation in the magnitude of renal blood flow in response to intrarenal arterial injection of dopamine, phenylephrine and isoprenaline. Renal vascular responses were blunted in WKY and SHR treated with either losartan or carvedilol as compared to their untreated counterparts (P<0.05). In the combined treated rats, the vascular responses to isoprenaline and phenylephrine were restored to levels observed in the untreated rats, but the renal vasoconstrictor responses to dopamine decreased (P<0.05) in both WKY and SHR. There was a reduction of (P<0.05) in the magnitude of the isoprenaline induced renal vasodilation in all SHR as compared to WKY groups. The data obtained showed that the renal vascular action of dopamine, phenylephrine and isoprenaline depended on an intact renin-angiotensin system (RAS) in WKY and SHR. Treatment with losartan or carvedilol blunted the renal vasoconstrictor/vasodilator responses to sympathomimetics which was attenuated with the combined treatment. These observations using chronic blockade of adrenergic and angiotensin receptors demonstrated that there was a long standing interdependency between the RAS and sympathetic nervous system (SNS) in determining the responsiveness of the renal vasculature of normal and hypertensive rats.

    1. This study was undertaken to elucidate the effects of inhibiting the renin-angiotensin system (RAS) with losartan, and acute unilateral renal denervation on renal haemodynamic responses to intrarenal administration of vasoconstrictor doses of dopamine and vasodilator doses of isoprenaline in Wistar-Kyoto (WKY) and spontaneously hypertensive rats (SHR). 2. Acute unilateral renal denervation of the left kidney in rats was confirmed by a drop in the renal vasoconstrictor response to renal nerve stimulation (P < 0.05) along with diuresis and natriuresis. Rats were pretreated with losartan for 7 days and thereafter animals fasted overnight were anaesthetized (sodium pentobarbitone, 60 mg/kg i.p.) and acute renal haemodynamic responses studied. 3. Dose-response curves were constructed for dopamine and isoprenaline that induced falls or increases in renal blood flow, respectively. It was observed that renal vascular responses were greater in the denervated as compared with rats with intact renal nerves (all P < 0.05). Dopamine-induced renal vasoconstrictor responses were markedly lower in losartan-treated denervated WKY and SHR compared with their untreated counterparts (all P < 0.05). It was also observed that in losartan-treated and denervated WKY rats the vasodilatory responses to isoprenaline were markedly lower compared with untreated rats (all P < 0.05). However, in SHR, under the same conditions, there was no difference in the renal response to isoprenaline whether or not rats were treated with losartan (P > 0.05). 4. The data obtained showed that the renal vasoconstrictor effect of dopamine depends on intact renal nerves and RAS in WKY and SHR. Isoprenaline responses were likewise sensitive to renal denervation and RAS inhibition in WKY rats but not SHRs. Our observations reveal a possible relationship between renal AT(1) receptors and alpha(1)-adrenoceptors in WKY and SHR. There is also evidence to suggest an interaction between renal beta-adrenoceptors and AT(1) receptors in WKY rats.

    1 This study was undertaken to characterize the renal responses to acute unilateral renal denervation in anaesthetized spontaneously hypertensive rats (SHR) by examining the effect of acute unilateral renal denervation on the renal hemodynamic responses to a set of vasoactive agents and renal nerve stimulation. 2 Twenty-four male SHR rats underwent acute unilateral renal denervation and the denervation was confirmed by significant drop (P < 0.05) in renal vasoconstrictor response to renal nerve stimulation along with marked diuresis and natriuresis following denervation. After 7 days treatment with losartan, the overnight fasted rats were anaesthetized (sodium pentobarbitone, 60 mg kg(-1) i.p.) and renal vasoconstrictor experiments were performed. The changes in the renal vasoconstrictor responses were determined in terms of reductions in renal blood flow caused by renal nerve stimulation or intrarenal administration of noradrenaline, phenylephrine, methoxamine and angiotensin II. 3 The data showed that there was significantly (all P < 0.05) increased renal vascular responsiveness to the vasoactive agents in denervated rats compared to those with intact renal nerves. In losartan-treated denervated SHR rats, there were significant (all P < 0.05) reductions in the renal vasoconstrictor responses to neural stimuli and vasoactive agents as compared with that of untreated denervated SHR rats. 4 The data obtained in denervated rats suggested an enhanced sensitivity of the alpha(1)-adrenoceptors to adrenergic agonists and possible increase of AT(1) receptors functionality in the renal vasculature of these rats. These data also suggested a possible interaction between sympathetic nervous system and renin-angiotensin system in terms of a crosstalk relationship between renal AT(1) and alpha(1)-adrenoceptor subtypes.

    BACKGROUND:
    Home blood pressure monitoring (HBPM) is gaining popularity among hypertensive patients. This study aimed to explore the influence of self-initiated HBPM on primary care patients with hypertension.
    METHODS:
    Six in-depth interviews and two focus group discussions were conducted, taking into consideration the experiences of 24 primary care patients with hypertension. These patients had been using HBPM as part of their hypertension management. The overriding influences were grouped under themes which emerged from analyzing the data using the grounded theory approach.
    RESULTS:
    There are both positive and negative influences of self-initiated HBPM. Patients used the readings of their HBPM to decide on many aspects of their hypertension management. The HBPM readings both influenced their adherence to diet and exercise and provided certain reassurance when they experienced symptoms. In addition, the act of discussing their HBPM readings with their health care providers resulted in an enhanced doctor-patient therapeutic relationship. Nevertheless, HBPM created confusion at times in some patients, particularly with regard to the target blood pressure level and the need for medication. This led to some patients making their own medical decisions based on their own standards.
    CONCLUSIONS:
    HBPM is becoming an integral part of hypertension management. Primary care patients who self-initiated HBPM reported being more self-efficacious, but lack of participation and guidance from their doctors created confusion, and hindered the true benefit of HBPM.

    BACKGROUND: Telemonitoring of home blood pressure (BP) is found to have a positive effect on BP control. Delivering a BP telemonitoring service in primary care offers primary care physicians an innovative approach toward management of their patients with hypertension. However, little is known about patients' acceptance of such service in routine clinical care.
    OBJECTIVE: This study aimed to explore patients' acceptance of a BP telemonitoring service delivered in primary care based on the technology acceptance model (TAM).
    METHODS: A qualitative study design was used. Primary care patients with uncontrolled office BP who fulfilled the inclusion criteria were enrolled into a BP telemonitoring service offered between the period August 2012 and September 2012. This service was delivered at an urban primary care clinic in Kuala Lumpur, Malaysia. Twenty patients used the BP telemonitoring service. Of these, 17 patients consented to share their views and experiences through five in-depth interviews and two focus group discussions. An interview guide was developed based on the TAM. The interviews were audio-recorded and transcribed verbatim. Thematic analysis was used for analysis.
    RESULTS: Patients found the BP telemonitoring service easy to use but struggled with the perceived usefulness of doing so. They expressed confusion in making sense of the monitored home BP readings. They often thought about the implications of these readings to their hypertension management and overall health. Patients wanted more feedback from their doctors and suggested improvement to the BP telemonitoring functionalities to improve interactions. Patients cited being involved in research as the main reason for their intention to use the service. They felt that patients with limited experience with the internet and information technology, who worked out of town, or who had an outdoor hobby would not be able to benefit from such a service.
    CONCLUSION: Patients found BP telemonitoring service in primary care easy to use but needed help to interpret the meanings of monitored BP readings. Implementations of BP telemonitoring service must tackle these issues to maximize the patients' acceptance of a BP telemonitoring service.

    Introduction: Prehypertension precedes overt hypertension and has been acknowledged by many guidelines.
    Hypertension is an important risk factor for cardiovascular disease in Malaysia. Hypertension prevalence is
    at 42.6% and population-based control is poor at 26.8%. The objective of the study is to ascertain the
    cardiovascular risk profile of prehypertensive and mildly hypertensive young adults against age-matched
    controls in rural Malaysia. Methods: 484 (four hundred and eighty four) subjects attending primary care
    clinic were screened. 91 (Ninety one) young adults with pre/mild hypertension and normotensive, agematched controls were enrolled. The blood pressure and biochemical profiles for both groups were assessed
    and compared. Results: Fifty-four subjects and 37 controls were enrolled. Amongst subjects, 46.3% had
    prehypertension and 53.7% had mild hypertension. Mean values compared to age-matched controls for MAP
    were 102.68 ± 7.48 vs 83.25 ± 6.08 mmHg (p< 0.001), LDL 3.75 ± 0.95 vs 3.32 ± 0.93 mmol/L (p=0.03), FBG
    4.65 ± 0.54 vs 4.33 ± 0.42 mmol/L (p=0.03), BMI 28.81 ± 5.16 vs 24.12 ± 4.91 (p< 0.001). The mean BP was
    significantly associated with BMI, FBG, triglycerides, HDL and the TC/HDL ratio. Conclusions: Greater BMI,
    FBG, HDL, triglyceride levels and TC/HDL ratio characterised the young adults with pre/mild hypertension.
    The data suggests that hypertension in young adults is secondary to metabolic syndrome.

    Adherence to antiretroviral therapy (ART) prevents disease progression, and the emergence of resistant mutations. It also reduces morbidity, and the necessity for more frequent, complicated regimens which are also relatively more expensive. Minimum adherence levels of 95% are required for treatment success. Poor adherence to treatment remains a stumbling block to the success of treatment programs. This generates major concerns about possible resistance of the human immunodeficiency virus (HIV) to the currently available ARVs. This paper aims to describe baseline results from a cohort of 242 Malaysian patients receiving ART within the context of an intervention aimed to improve adherence and treatment outcomes among patients initiating ART. A single-blinded Randomized Controlled Clinical Trial was conducted between January and December, 2014 in Hospital Sungai Buloh. Data on socio-demographic factors, clinical symptoms and adherence behavior of respondents was collected using modified, pre-validated Adult AIDS Clinical Trials Group (AACTG) adherence questionnaires. Baseline CD4 count, viral load, weight, full blood count, blood pressure, Liver function and renal profile tests were also conducted and recorded. Data was analyzed using SPSS version 22 and R software. Patients consisted of 215 (89%) males and 27 (11%) females. 117 (48%) were Malays, 98 (40%) were Chinese, 22 (9%) were Indians while 5 (2%) were of other ethnic minorities. The mean age for the intervention group was 32.1 ± 8.7 years while the mean age for the control group was 34.7 ± 9.5 years. Mean baseline adherence was 80.1 ± 19.6 and 85.1 ± 15.8 for the intervention and control groups respectively. Overall mean baseline CD4 count of patients was 222.97 ± 143.7 cells/mm³ while overall mean viral load was 255237.85 ± 470618.9. Patients had a mean weight of 61.55 ± 11.0 kg and 61.47 ± 12.3 kg in the intervention and control groups, respectively. Males account for about 90% of those initiating ART in the HIV clinic, at a relatively low CD4 count, high viral load and sub-optimal medication adherence levels at baseline.

    INTRODUCTION: Hypertension is extremely common disease found in patients with diabetes mellitus. Eighty to 90% of patients with type 2 diabetes mellitus will develop hypertension, and about 20% of hypertensive patients develop diabetes. The aim of this study was designed to assess the prevalence of hypertension and factors affecting the control of hypertension among type 2 diabetic patients.
    MATERIALS AND METHODS: A total of 1077 type 2 diabetes mellitus patients were included in this study who attended at diabetes clinic of Universiti Sains Malaysia (USM) teaching hospital in Kelantan. All these patients were prospectively followed from January to December 2008. Logistic regression analysis was used to assess the independent effect of variables on hypertension.
    RESULTS: The prevalence of hypertension (BP>130/80 or on medication for high blood pressure) was 92.7%. A total 471 (47.2%) patients had achieved blood pressure targets ≤ 130/80 mmHg. The logistic regression indicated that hypertension was positively associated with age (P=0.040), BMI (P=0.027), HbA1c (P=0.046), and level of education (P=0.039).
    CONCLUSION: Hypertension is a common co-morbidity among diabetic patients. Hypertension was not controlled to the recommended levels of blood pressure in about one-half (52.8%) of diabetes patients. Age, BMI, HbA1c and level of education are factors affecting on hypertension.

    AIMS: To determine the prevalence of hypertension, control of hypertension and patterns of antihypertensive medications in Malaysian type 2 diabetic patients who attended diabetes clinics in Hospital University Sains Malaysia (Tertiary Hospital).
    MATERIALS AND METHODS: The study design was observational prospective longitudinal follow-up study; the study was conducted with sample of 1077 type 2 diabetes mellitus outpatient recruited whom attended the diabetes clinics at Hospital Universiti Sains Malaysia (HUSM) in Kelantan. The study period was from January till December 2008. Blood pressure was defined as >130/80 or use of antihypertension medications. Demographic characteristics of patients, level of blood pressure control, use of antihypertensive medications and patterns of antihypertensive therapy.
    RESULTS: The prevalence of hypertension in Malaysian type 2 diabetic patients was 998 (92.7%),antihypertensive drugs were prescribed in 940 (94.2%) of hypertensive patients with type 2 diabetic mellitus. The achievement of blood pressure control (≤130/80 mmHg) was 471 (47.2%) %. The percentage of patients receiving one, two, three, and four drugs were 253 (25.3%), 311 (31.3%), 179 (17.9%), and 197 (19.7%) respectively. Calcium channel blockers were the most commonly prescribed antihypertensive agents 757 (75.7%) followed by Angiotensin-converting enzyme inhibitors 446 (44.6%), and Angiotensin receptor blockers 42.4 (42.4%).
    CONCLUSION: The prevalence of hypertension is high in Malaysian type 2 diabetic patients, hypertension was not controlled to the recommended levels of blood pressure in about one-half (52.8%) of diabetes patients. Calcium channel blockers were the most commonly prescribed antihypertensive agents. There is an urgent need to educate both patients and health care providers of importance of achieving target of treatment in order to reduce morbidity and mortality due to diabetes with hypertension.

    In order to examine whether erythrocyte membrane handling of sodium is influenced by factors other than hypertension, measurements of red cell sodium transport were studied in one hundred normotensive volunteers. Erythrocyte sodium content was found to increase with increasing age, body weight and mean arterial pressure (MAP). It is also significantly correlated with age, body weight and MAP. Total sodium efflux was found to be reduced and negatively correlated with age and body weight. A reduction in ouabain-sensitive sodium efflux was also observed with increasing age and body weight. In males, the rate of ouabain-sensitive sodium efflux is higher than in females. Race was found to have no effect on erythrocyte electrolyte content and cationic flux rates of subjects. These data suggest that when studies in hypertension are going to be carried out, control subjects carefully matched for age, body weight and sex should be used if confounding results are not to be obtained.

    Introduction: In this study, Renal artery (RA) stenosis of Single Stenosed (SS) and Double Stenosed (DS) with the condition of Normal Blood Pressure (NBP) and High Blood Pressure (HBP) were investigated using the aid of Fluid Structure Interaction (FSI) approach. Methods: Numerical analysis of 3D model patient’s specific abdominal aorta with RA stenosis was conducted using FSI solver in software ANSYS 18. Results: The results of velocity profile, pres- sure drop, time average wall shear stress (TAWSS), Oscillatory shear index (OSI) and total deformation of SS and DS with the condition of NBP and HBP were compared in terms of blood flow and structural wall tissue behaviour. The results concluded SS-NBP produced the highest value of velocity profile, TAWSS and OSI parameter compared to the others. Meanwhile, SS-HBP indicates the highest value pressure drop. On the other hand, SS-HBP and DS-HBP have a higher distribution of deformation contour and also maximum VMS compared to SS-NBP and DS-HBP. Conclusion: With the aid of FSI approach, this studied has proven that the existence of SS at RA location has a higher impact on the velocity magnitude, higher pressure drop, higher TAWSS and OSI value compared to the DS case. This is due to a high concentration of pressure acting at the narrow blood vessel of SS compared to DS cases which most of the blood flow will pass to the lower part of abdominal aorta.
