    Over a thousand subjects who visited a city private medical clinic for health screening and advice were examined for their lipid profile and other cardiovascular risk factors. The mean TC, TG, LDL-C and HDL-C were 5.43, 1.45, 3.61 and 1.15 mmol/l. Their derived ratios viz, TC:HDL-C and LDL:HDL-C were 5.11 and 3.43 respectively. The prevalence of hyperlipidaemia was moderately high. Of the subjects studied 58.5% had elevated serum cholesterol, 14.8% had raised triglycerides, 64.9% had raised LDL-C and 20.8% had low HDL-C. Male subjects generally showed higher mean values and abnormality frequency in TC, TG, LDL-C, TC:HDL-C and LDL:HDL-C as compared to female subjects. Although significant ethnic differences were not detected for certain lipid parameters (e.g. TC, TG and HDL-C), the Indians appeared to have higher mean lipid values (except HDL-C), and higher percentage abnormality for all the lipid parameters as compared to the Chinese and the Malays. In correlation studies, the following lipid parameters:- TC versus TG, LDL-C, TC:HDL-C; TG versus TC:HDL-C and LDL:HDL-C; LDL-C versus TC:HDL-C and LDL:HDL-C; were positively correlated. On the other hand, TC versus HDL-C, TG versus HDL-C, LDL-C and HDL-C, and HDL-C versus TC:HDL-C and LDL:HDL-C were negatively correlated. The coronary risk factors which generally showed positive correlations with lipid parameters were BMI and blood pressure. Positive correlations were also recorded between fasting blood glucose and TG; uric acid with TG, TC:HDL-C and LDL:HDL-C. In contrast, risk factors of negative correlations were observed between HDL-C and the coronary risk factors of BMI, diastolic blood pressure and uric acid. Smoking showed raised per cent lipid abnormality for TG, HDL-C, TC:HDL-C and LDL:HDL-C. Alcohol consumption also increased the mean level and abnormality frequency for TG. The implication of this investigation is discussed.

    One hundred consecutive patients with coronary heart disease attending the Physician Clinic, Kuala Terengganu General Hospital self-completed a questionnaire on their awareness of the coronary risk factors and their perception of their disease. Seventy-one subjects were males. Twenty-seven subjects had never had formal education and only 6 had completed tertiary education. Whilst 52% considered themselves as having less than 25% knowledge about their disease, many were aware of hypercholesterolaemia, emotional stress, inadequate exercise and smoking as risk factors for coronary heart disease. Diabetes and family history were less known as coronary risk factors. Despite their awareness of the risk factors, though, the subjects failed to control these. For example, smoking was prevalent and their awareness of the harmful effects of smoking did not seem to deter them from this habit. Further, formal education did not seem to influence positive health behaviour. In terms of disease perception, the subjects tended to believe that their illness could be cured. Eighty subjects expected a cure from their doctors. Sixty-three subjects wanted more explanation of their illness from their doctors. These findings suggest that efforts should be made to translate patients' awareness of their illness to appropriate health behaviour, and perhaps doctors could achieve this by spending more time explaining to the patients, and educating them.

    The concentrations of non-haem iron, ferritin and ferritin-iron were measured in the livers of 137 adults and children collected at necropsy. The concentrations of non-haem and ferritin iron were found to be 146.6 +/- 95.2 micrograms/g and 61.6 +/- 32.4 micrograms/g, respectively, in males and 108.0 +/- 61.7 micrograms/g and 60.6 +/- 26.4 micrograms/g, respectively, in females. The values for males in Singapore were lower than those reported in developed Western countries. No correlation was observed between storage iron and age, or ferritin concentration and age. Concentrations of non-haem iron and ferritin were similar for persons dying from accident and coronary heart disease. The non-haem iron concentration in Chinese (187.9 +/- 101.0 micrograms/g) was significantly greater than that in Indians (103.1 +/- 65.8 micrograms/g), while the ferritin concentration in Chinese (6.18 +/- 2.37 mg/g) was significantly greater than either Malays (3.81 +/- 1.8 mg/g) or Indians (3.52 +/- 1.6 mg/g). A significant positive correlation was observed between the non-haem iron and ferritin and also ferritin-iron in Chinese males (r values of 0.678 and 0.598, respectively) and Indian males (r values of 0.576 and 0.612, respectively). However, the correlation between these indices was not significant in the case of Malay males. In premenopausal women the non-haem iron correlated well with ferritin (r = 0.737) and ferritin iron (r = 0.826) while the correlation was lacking in postmenopausal women.

    Chlamydophila pneumoniae, an important respiratory pathogen causing lower respiratory tract infections, has also been implicated in coronary heart disease (CHD). This study reports a cross-sectional, demographic, serological analysis of the prevalence of Chlamydophila pneumoniae antibodies in a multiracial Malaysian population. Generally, Malaysian Indians had the highest degree of seropositivity (58%) followed by the Chinese (54%) and the Malays (32%), results which were statistically significant (CI: 95%; p < 0.01). Interestingly, this trend was also reflected in the study group consisting of patients with acute myocardial infarctions (AMI) and chronic CHD. Again, the Indians were more frequently seropositive (65%), with more than 50% having IgG titres > or = 128. Comparatively, the Chinese and Malays showed 51 and 17% seropositivity respectively. These results were also statistically significant (CI: 95%; p < 0.01). Malaysian Indians are more commonly afflicted with CHD. A variety of factors have been suggested to explain this prevalence including diet, social habits, genetics and the possible role of infectious agents. This study notes an interesting association between this pattern of racial prevalence and the possible role of C. pneumoniae infections as a contributory/predisposing factor in the development of cardiovascular disease.

    Conventional therapies for severe ischemic heart disease are limited in applicability. While several angiogenesis researches have shown novel efficacy, safety and feasibility for clinical use, recently we have started the clinical trial of a sole cell therapy using autologous bone marrow mononuclear cells transplantation targeted into ischemic hibernating myocardium. Here, we review the background of bone marrow cell research and introduce therapeutic angiogenesis for severe ischemic heart disease by autologous bone marrow cells transplantation.

    Coronary heart disease which was responsible for 2.9% of all deaths 30 years ago, today accounts for 19% of deaths. The rising trend which declined in 1985, appears to be stabilising now. Indians have mortality rates which are 3 times that of Chinese. This is the background against which the Singapore Myocardial Infarction Register was set up in 1967 to provide incidence and prevalence data for coronary heart disease in the country. in 1987 to provide incidence and prevalence data for coronary heart disease in the country.

    OBJECTIVE: Depression is a risk factor for coronary heart disease and left ventricular hypertrophy (LVH) is a potent predictor of coronary heart disease events. Whether depression is associated with LVH has received limited investigation. This study assessed cross-sectional and 20-year longitudinal associations of depressive symptoms with LVH outcomes after accounting for important known confounders.

    METHODS: From 5115 participants enrolled in 1985-1986 in the Coronary Artery Risk Development in Young Adults Study, 2533 had serial measures of depressive symptoms and subsequent echocardiography to measure normal LV geometry, concentric remodeling, and LVH. The primary exposure variable was trajectories of the Center for Epidemiologic Studies Depression (CES-D) scale score from 1990-1991 to 2010-2011. Multivariable polytomous logistic regression was used to assess associations of trajectories with a composite LV geometry outcome created using echocardiogram data measured in 2010-2011 and 2015-2016. Sex-specific conflicting results led to exploratory models that examined potential importance of testosterone and sex hormone-binding globulin.

    RESULTS: Overall CES-D and Somatic subscale trajectories had significant associations with LVH for female participants only. Odds ratios for the subthreshold (mean CES-D ≈ 14) and stable (mean CES-D ≈ 19) groups were 1.49 (95% confidence interval = 1.05-2.13) and 1.88 (95% confidence interval = 1.16-3.04), respectively. For female participants, sex hormone-binding globulin was inversely associated with LVH, and for male participants, bioavailable testosterone was positively associated with concentric geometry.

    CONCLUSIONS: Findings from cross-sectional and longitudinal regression models for female participants, but not male ones, and particularly for Somatic subscale trajectories suggested a plausible link among depression, androgens, and LVH. The role of androgens to the depression-LVH relation requires additional investigation in future studies.

    OBJECTIVES: The current study aims to determine the relationship of long-term visit-to-visit variability of SBP to cardiovascular disease (CVD) in a multiethnic primary care setting.
    METHOD: This is a retrospective study of a cohort of 807 hypertensive patients over a period of 10 years. Three-monthly clinic blood pressure readings were used to derive blood pressure variability (BPV), and CVD events were captured from patient records.
    RESULTS: Mean age at baseline was 57.2 ± 9.8 years with 63.3% being women. The BPV and mean SBP over 10 years were 14.7 ± 3.5 and 142 ± 8 mmHg, respectively. Prevalence of cardiovascular event was 13%. In multivariate logistic regression analysis, BPV was the predictor of CVD events, whereas the mean SBP was not independently associated with cardiovascular events in this population. Those with lower SBP and lower BPV had fewer cardiovascular events than those with the same low mean SBP but higher BPV (10.5 versus 12.8%). Similarly those with higher mean SBP but lower BPV also had fewer cardiovascular events than those with the same high mean and higher BPV (11.6 versus 16.7%). Other variables like being men, diabetes and Indian compared with Chinese are more likely to be associated with cardiovascular events.
    CONCLUSION: BPV is associated with an increase in CVD events even in those who have achieved lower mean SBP. Thus, we should prioritize not only control of SBP levels but also BPV to reduce CVD events further.

    In Singapore. there exists differences in risk factors for coronary heart disease among the three main ethnic groups: Chinese, Malays and Indians. This study aimed to investigate if differences in dietary intakes of fat, types of fat, cholesterol, fruits, vegetables and grain foods could explain the differences in serum cholesterol levels between the ethnic groups. A total of 2408 adult subjects (61.0% Chinese, 21.4% Malays and 17.6% Indians) were selected systematically from the subjects who took part in the National Health Survey in 1998. The design of the study was based on a cross-sectional study. A food frequency questionnaire was used to assess intakes of energy, total fat, saturated fat, polyunsaturated fat, monounsaturated fat, cholesterol, fruits, vegetables and cereal-based foods. The Hegsted score was calculated. Serum total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol were analysed and the ratio of total cholesterol to high density lipoprotein cholesterol was computed. The results showed that on a group level (six sex-ethnic groups), Hegsted score, dietary intakes of fat, satutrated fat, cholesterol, vegetables and grain foods were found to be correlated to serum cholesterol levels. However, selected dietary factors did not explain the differences in serum cholesterol levels between ethnic groups when multivariate regression analysis was performed, with adjustment for age, body mass index, waist-hip ratio, cigarette smoking, occupation, education level and physical activity level. This cross-sectional study shows that while selected dietary factors are correlated to serum cholesterol at a group level, they do not explain the differences in serum cholesterol levels between ethnic groups independently of age, obesity, occupation, educational level and other lifestyle risk factors.

    Mutations in the ATP-binding cassette transporter ABCA1 underlie Tangier disease and familial hypoalphaliproteinemia (FHA), disorders that are characterised by reduced high-density lipoprotein-cholesterol (HDL-C) concentration and cholesterol efflux, and increased coronary artery disease (CAD). We explored if polymorphisms in the ABCA1 gene are associated with CAD and variations in plasma lipid levels, especially HDL-C, and whether the associations may depend on ethnicity. Male cases and controls from the Singapore Chinese, Malay and Indian populations were genotyped for five ABCA1 single nucleotide polymorphisms. Various single-locus frequency distribution differences between cases and controls were detected in different ethnic groups: the promoter -14C>T in Indians, exon 18 M883I in Malays, and 3'-untranslated (UTR) region 8994A>G in Chinese. For the Malay population, certain haplotypes carrying the I825- A (exon 17) and M883- G alleles were more frequent among cases than controls, whereas the converse was true for the alternative configuration of V825- G and I883- A, and this association was reinforced in multi-locus disequilibrium analysis that utilized genotypic data. In the healthy controls, associations were found for -14C>T genotypes with HDL-C in Chinese; 237indelG (5'UTR) with apolipoprotein A1 (apoA1) in Malays and total cholesterol (TC) in Indians; M883I with lipoprotein(a) [Lp(a)] in Malays and apolipoprotein B (apoB) in Chinese; and 8994A>G with Lp(a) in Malays, and TC, low-density lipoprotein-cholesterol (LDL-C) as well as apoB in Indians. While genotype-phenotype associations were not reproduced across populations and loci, V825I and M883I were clearly associated with CAD status in Malays with no effects on HDL-C or apoA1.

    Haematologic abnormalities are found in patients who develop acute ischaemic syndromes including acute myocardial infarction (AMI). A coronary care unit population of 660 consecutive patients were studied for their haematologic parameters on admission. There were 263 patients who had AMI, 207 who had non-infarct acute ischaemic syndromes (CAD), and the other 190 non-coronary patients served as controls. Overall patients with AMI had signijicantly higher haemoglobin (145 ± 2.2 vs 12.9 ± 3.0 g/dl, p<0.0001), haematocrit (45.4 ± 5.8% vs 41.2 ± 8.8%. P < 0.001). red cell count (5.0 ± 0.7 vs 4.5 ± 10^12 p<0.001), but there were no significant differences in their leucocyte count, platelet count or mean corpuscular volume. Patients with CAD had higher haemoglobin and red cell counts (p<0.002, p<0.02 respectively). Although infarct women tended to have lower counts (p<0.001), they still had significantly higher haemoglobin (p<0.01), haematocrit (p<0.02) and red cell count(p<0.002) when compared with controls. Interestingly, there were no ethnic differences at all with regard to haematologic values for infarct patients; haemoglobin, haematocrit, and red count were each significantly higher than controls. Our results suggest that a relatively high baseline Hb, haematocrit or RBC count may be associated with increased likelihood of acute ischaemic syndromes including AMI among Malaysians. Increased viscosity and abnormal haemorheological characteristics may contribute to the development and subsequent outcome of unstable coronary syndromes. Keywords: acute myocardial infarction, coronary artery disease, haemoglobin, haematocrit, haemorheology.

    Cardiovascular diseases are one of the most prevalent diseases worldwide, and its rate of mortality is rising annually. In accordance with the current condition, studies on medicinal plants upon their activity on cardiovascular diseases are often being encouraged to be used in cardiovascular disease management, due to the availability of medicinal values in certain dedicated plants. This review was conducted based on two plant families, which are Asteraceae and Lamiaceae, to study on their action in cardiovascular disease relieving activities, to review the relationship between the phytochemistry of Asteraceae and Lamiaceae families and their effect on cardiovascular diseases, and to study their toxicology. The medicinal plants from these plant family groups are collected based on their effects on the mechanisms that affect the cardiovascular-related disease which are an antioxidant activity, anti-hyperlipidemic or hypocholesterolemia, vasorelaxant effect, antithrombotic action, and diuresis effect. In reference to various studies, the journals that conducted in vivo or in vitro experiments, which were used to prove the specific mechanisms, are included in this review. This is to ensure that the scientific value and the phytochemicals of the involved plants can be seen based on their activity. As a result, various plant species from both Asteraceae and Lamiaceae plant family have been identified and collected based on their study that has proven their effectiveness and uses in cardiovascular diseases. Most of the plants have an antioxidant effect, followed by anti-hyperlipidemia, vasorelaxant, antithrombotic, and diuretic effect from the most available to least available studies, respectively. These are the mechanisms that contribute to various cardiovascular diseases, such as heart attack, stroke, coronary heart disease, and hypertension. Further studies can be conducted on these plant species by identifying their ability and capability to be developed into a new drug or to be used as a medicinal plant in treating various cardiovascular diseases.

    Clopidogrel is a widely-used antiplatelet drug. It is important for the treatment and prevention of coronary heart disease. Clopidogrel can effectively reduce platelet activity and therefore reduce stent thrombosis. However, some patients still have ischemic events despite taking the clopidogrel due to the alteration in clopidogrel metabolism attributable to various genetic and non-genetic factors. This review aims to summarise the mechanisms and causes of clopidogrel resistance (CR) and potential strategies to overcome it. This review summarised the possible effects of genetic polymorphism on CR among the Asian population, especially CYP2C19 *2 / *3 / *17, where the prevalence rate among Asians was 23.00%, 4.61%, 15.18%, respectively. The review also studied the effects of other factors and appropriate strategies used to overcome CR. Generally, CR among the Asian population was estimated at 17.2-81.6%. Therefore, our overview provides valuable insight into the causes of RC. In conclusion, understanding the prevalence of drug metabolism-related genetic polymorphism, especially CYP2C19 alleles, will enhance clinical understanding of racial differences in drug reactions, contributing to the development of personalised medicine in Asia.

    Introduction: Depression is the most common psychiatric disorder among the elderly. The hallmark of depression in the elderly is its comorbidity with medical illness. Aim: To determine the prevalence of depression and its association with chronic illness among the elderly in a rural community setting. Methods: A cross sectional study design was used. A 30-item Geriatric Depression Scale questionnaire was used as a screening instrument. Results: The prevalence of depression was higher among elderly with chronic illness (9.0%) compared to elderly without chronic illness (5.6%). Depression among the elderly was signi.cantly associated with ischemic heart disease. Conclusion: The prevalence of depression among the elderly with chronic illness in the community is high. Primary care providers need to be vigilant when treating elderly patients in their care as depression is commonly found in this group.

    Study name: National Health and Morbidity Survey (NHMS-1986)

    National Health and Morbidity Survey (NHMS) was first initiated in 1986. Its objectives were to supplement existing data on the pattern of health problems, health needs and expenditure on health in the community to enable the Ministry of Health to review priorities and activities of programmes, plan future allocation of resources and evaluate the impact of strategies.
    The scopes covered in the survey were morbidity rates, health service utilizations and their barriers, health expenditure and their sources, immunization coverage, acute respiratory illness, hypertension, angina, smoking, diabetes, astma and injuries. The survey only focused in Peninsular Malaysia with response rate in different modules ranging from 92 to 100%. The survey was spearheaded by the Institute for Public Health (IPH) and partially supported by the World Health Organisation (WHO) Grant.
    The scopes covered in this survey were load of illness, health seeking behaviour, health care consumption cost, health related behaviours (exercise, breast-feeding practices, pap-smear examination, breast examination, smoking, alcohol consumption, obesity, adolescent risky behaviour: smoking, alcohol consumption, drug abuse, sexual practices), specific health problems (hypertension, ischaemic heart disease, diabetes mellitus, medically diagnosed cancer, injury, physical impairments, astman and acuter respiratory inflections), and blood cholesterol level. The response rate at Living Quarters (LQ) level was 86.9%.
