    This study describes the physical activity of primary school children according to sociodemographic characteristics and activity domains. Using the Malaysian South East Asian Nutrition Surveys data, 1702 children aged 7 to 12 years were included in the analysis. Physical activity was reported as a total score and categorized into low, medium, and high levels based on Physical Activity Questionnaire for Older Children. Higher overall activity scores were found in boys, younger age, non-Chinese ethnicity, and normal body mass index category. Sex, age, and ethnicity differences were found in structured or organized, physical education, and outside-of-school domain scores. Transport-related scores differed by age group, ethnicity, household income, and residential areas but not among the three physical activity levels. Participation of girls, Chinese, and older children were low in overall and almost all activity domains. Sociodemographic characteristics are important factors to consider in increasing the different domains of physical activity among Malaysian children.

    Introduction: The flow-volume curves of patients with obstructive sleep apnoea (OSA) obtained during the awake state are frequently abnormal.
    Objective: To determine 1) the relationship between the awake respiratory function and the severity of sleep-disordered breathing in a group of Malaysian patients with the OSA syndrome and 2) the frequency of flow-volume curve abnormality in these patients.
    Materials and methods: A retrospective analysis of the data from respiratory function tests during wakefulness and nocturnal polysomnography was performed on 48 patients with OSA. The severity of OSA was defined by the apnoea-hypopnoea index (AHI) and the lowest oxygen saturation during sleep (SPO2nadir).
    Results: AHI had a significant relationship with alveolar-arterial oxygen gradient (r=0.34, p=0.046) and SPO2nadir (r=0.049, p<0.001) but not with any anthropometric parameter or the other awake respiratory function variables measured SPO2nadir, has a significant relationship with body mass index (r=0.54, P<0.001), neck circumference (r=-0.39, p=0.013), awake room air PaO2 (r=0.61, p<0.001), alveolar-arterial oxygen gradient (r=-0.41, p=0.015) and baseline supine SpO2 (r=0.53, p<0.001). there was no correlation between SPO2nadir and any spirometric or static lung volume parameters. The maximum inspiratory and maximum expiratory flow volume curves of 26 patients (54%) showed a ratio of forced expiratory flow to forced inspiratory flow at mid-vital capacity (FEF50/FIF50) greater than one. In addition, flow oscillations (the ‘sawtooth’ sign) were noted in the inspiratory and/or expiratory flow-volume curves of 21 patients (44%), 9 of who did not have an FEF50/FIF50>1. Altogether, the maximum flow-volume curves during wakefulness of 35 (&3%) of the 48 patients showed variable upper airway obstruction and/or flow oscillations. However, the presence of these two upper airway abnormalities, either occurring alone or together did not have an effect on the severity of OSA as measured by the AHI or SPO2nadir.
    Conclusions: Abnormalities of the flow-volume loop consistent with inspiratory flow limitation and/or upper airway instability during wakefulness are common in patients with the OSA syndrome. The degree of oxygen desaturation during sleep in these patients as related to their awake oxygenation status.

    The various technological advancements in computed tomography (CT) have resulted in remarkable growth in the use of CT imaging in clinical practice, not the least of which has been its establishment as the most valuable imaging examination for the assessment of cardiovascular system disorders. The objective of this study was to assess the effective radiation dose and radiation risk for patients during cardiac CT procedures, based on studies from four different hospitals equipped with 128 slice CT equipment. A total of eighty-three patients were investigated in this study with different clinical indications. Effective doses were also calculated using software based on Monte Carlo simulation. The mean patient age (years), weight (kg), and body mass index (BMI (kg/m2)) were 49 ± 11, 82 ± 12, and 31 ± 6, respectively. The results of the study revealed that the tube voltage (kVp) and tube current-exposure time product (mAs) ranged between 100 to 140 and 50 to 840 respectively. The overall average patient dose values for the volume CT dose index [(CTDIvol), in mGy)] and dose length product (DLP) (in mGy·cm) were 34.8 ± 15 (3.7-117.0) and 383.8 ± 354 (46.0-3277.0) respectively. The average effective dose (mSv) was 15.2 ± 8 (1.2-61.8). The radiation dose values showed wide variation between different hospitals and even within the same hospital. The results indicate the need to optimize radiation dose and to establish diagnostic reference levels (DRLs) for patients undergoing coronary computed tomography angiography (CCTA), also to harmonize the imaging protocols to ensure reduced radiation risk.

    Introduction: Implantation is one of critical step in human reproductive processes. There are many factors that affect successful implantation. Good quality embryo or blastocyst is a prerequisite to successful implantation together with a receptive endometrium. The purpose of this study is to describe the patient clinical profile and to investigate the factors of interest association with implantation status. Methods: This is a cross sectional study involving patients planned for in vitro fertilization (IVF) treatment in the hospital infertility clinic. All demographic data and clinical profile data of the patient in each visit was recorded. Among the data taken were, physical examination data, patient history, causes of infertility, hormonal investigation and outcome at the end of treatment (presence of fetal heart). Successful implantation is indicated by presence of fetal heart. Results: A total of 246 patients record were collected. Mean age of the patient was 34.2 (SD = 4.12) years old. Mean BMI was 24.5 kg/m2 (SD=4.70). Mean of infertility years among the patients was 5.9 years (SD= 3.40). Most cause of infertility was tubal issues 87 cases (35.4%). The prevalence of successful implantation was 12.8% ((95% CI 7.8%, 17.8%). None of the factors of interest (age, BMI, infertility duration, progesterone at baseline, progesterone at trigger day) were found associated with successful implantation. Out of 224 patients, 53 (21.5%) were having elevated progesterone level at trigger day. However, in this study, there is no conclusive evidence that level of progesterone is associated with successful implantation. Conclusion: The successful implantation in our setting is approximately 1/10 of IVF treatment. Implantation involved a complex mechanism, thus there is wide variety of etiologies to predict for successful implantation. Thus, further study on wide comprehensive of risk factors is warranted.

    The stress and anxiety caused by the coronavirus (COVID-19) pandemic presents a serious threat to psychological well-being in populations worldwide and may also extend to body image outcomes. To test this hypothesis, we conducted a preliminary study in which an online sample of adults from the United Kingdom (N = 506, age M = 34.25 years) were asked to complete measures of perceived stress, stressful life events, trait anxiety, COVID-19-related stress and anxiety, and negative body image (body dissatisfaction and drive for thinness in women, body fat and muscularity dissatisfaction in men). The results of hierarchical regressions indicated that COVID-19-related stress and anxiety explained significant incremental variance in body image outcomes (Adj. ΔR2 = .02 to .10), over-and-above demographics (age and body mass index) and perceived stress, trait anxiety, and stressful life events. These findings suggest that COVID-19-related stress and anxiety may shape body image outcomes under conditions of physical and social distancing.

    Background: Total knee replacement (TKR) is a major orthopedic surgery that is considered high risk for the development of venous thromboembolism (VTE).

    Objective: The aim of this study is to evaluate the clinical outcomes that resulted from the use of a new proposed VTE risk stratification protocol for selecting a suitable extended VTE prophylaxis for post TKR surgery patients administered in conjunction with patient education programs.

    Method: A randomized controlled trial was conducted in two medical centers in Saudi Arabia. A total of 242 patients were enrolled in the study, 121 patients in each group. The experimental group (A) was assessed by using the proposed VTE risk stratification protocol and also took part in patient education programs about TKR and its complications. The control group (B) was assessed by using the 2005 Caprini risk assessment tool and no education programs were given to this group. Both groups were followed for 35 days post operation.

    Results: The mean age of the participants was 65.86 (SD 8.67) and the majority of them were female 137 (56.6%). The mean body mass index of the study sample was 32.46 (SD 5.51). There were no significant differences between the two groups except for surgery type; the proportion of bilateral TKR in group A was higher than in group B (69/121 (28.5%) vs. 40/121(16.5%), p<0.05). There were no confirmed pulmonary embolism cases in the study sample and diagnosis of deep-vein thrombosis was confirmed in 12/242 (5.0%) of patients: 1/121 (0.8%) in group A and 11/121 (9.1%) in group B (p<0.05). The readmission rate for all patients was 2.5% (6/242), all of whom were in group B (p<0.05).

    Conclusion: The proposed VTE risk stratification protocol that was applied in conjunction with patient education programs reduced VTE complications and readmission events, post TKR surgery. Trial Registration: ClinicalTrials.gov: Identifier: NCT04031859.

    Background: The objective of this study was to determine the levels of serum ischemia-modified albumin (IMA), fibrinogen (FIB) and high sensitivity C-reactive protein (hs-CRP) in type 2 diabetes mellitus (T2DM) patients with hypertension (HT) (DMT2HTN) and without HT (DMT2). Also, their association with certain biochemical and physical factors were studied to identify possible risk factors that lead to cardiovascular complications.

    Methods: Fasting blood samples were collected from 35 DMT2 or DMT2HTN patients each to analyze differences in serum and plasma levels of IMA, hs-CRP, FIB, total cholesterol (TC), high and low density lipoproteins (HDL and LDL), triglyceride (TG), hemoglobin A1c (HbA1C), glycated hemoglobin and creatinine.

    Results: In DMT2 and DMT2HTN patients, IMA, hs-CRP, FIB, TC, TG, HDL, LDL, glycated hemoglobin and creatinine levels, including body mass index (BMI) and waist-to-hip ratio (WHR), were significantly higher relative to healthy controls. In addition, the levels of IMA, hs-CRP and FIB levels showed a strong link to BMI, WHR, TC, TG, LDL and glycated hemoglobin. Lastly, both DMT2 and DMT2HTN patients demonstrated a significant reduction in HDL.

    Conclusion: DMT2 and DMT2HTN patients have a greater risk of developing cardiovascular related complications. This study suggests that quantifying hs-CRP, IMA and FIB levels can help diagnose the risk of developing complications during the early stages of metabolic and cardiovascular disease. Overall, the specific risk factors may be used for early identification of cardiovascular complications to decrease mortality and morbidity in T2DM patients.

    OBJECTIVES: Intermittent hypoxemia is a risk factor for developing complications in obstructive sleep apnea (OSA) patients. The objective of this systematic review was to identify articles evaluating the accuracy of the oxygen desaturation index (ODI) as compared with the apnea-hypopnea index (AHI) and then provide possible values to use as a cutoff for diagnosing adult OSA.

    STUDY DESIGN: Systematic Review of Literature.

    METHODS: PubMed, the Cochrane Library, and SCOPUS databases were searched through November 2019.

    RESULTS: Eight studies (1,924 patients) met criteria (age range: 28-70.9 years, body mass index range: 21.9-37 kg/m2 , and AHI range: 0.5-62 events/hour). Five studies compared ODI and AHI simultaneously, and three had a week to months between assessments. Sensitivities ranged from 32% to 98.5%, whereas specificities ranged from 47.7% to 98%. Significant heterogeneity was present; however, for studies reporting data for a 4% ODI ≥ 15 events/hour, the specificity for diagnosing OSA ranged from 75% to 98%, and only one study reported the positive predictive value, which was 97%. Direct ODI and AHI comparisons were not made because of different hypopnea scoring, different oxygen desaturation categories, and different criteria for grading OSA severity.

    CONCLUSION: Significant heterogeneity exists in studies comparing ODI and AHI. Based on currently published studies, consideration should be given for diagnosing adult OSA with a 4% ODI of ≥ 15 events/hour and for recommending further evaluation for diagnosing OSA with a 4% ODI ≥ 10 events/hour. Screening with oximetry may be indicated for the detection of OSA in select patients. Further study is needed before a definitive recommendation can be made. Laryngoscope, 131:440-447, 2021.

    Aim: This study evaluated the relationship between missing posterior teeth and body mass index with regard to age and socioeconomic state in a sample of the suburban south Indian population.

    Materials and Methods: The 500 individuals of both males and females aged 40 years and older with missing posterior teeth and not rehabilitated with any prosthesis were gone through a clinical history, intraoral examination, and anthropometric measurement to get information regarding age, sex, socioeconomic status, missing posterior teeth, and body mass index (BMI). Subjects were divided into five groups according to BMI (underweight > 18.5 kg/m2, normal weight 18.5-23 kg/m2, overweight 23-25 kg/m2, obese without surgery 25-32.5 kg/m2, obese with surgery < 32.5 kg/m2). Multivariate logistic regression was used to adjust data according to age, sex, number of missing posterior teeth, and socioeconomic status.

    Results: People with a higher number of tooth loss were more obese. Females with high tooth loss were found to be more obese than male. Low socioeconomic group obese female had significantly higher tooth loss than any other group. No significant relation between age and obesity was found with regard to tooth loss.

    Conclusion: The BMI and tooth loss are interrelated. Management of obesity and tooth loss can help to maintain the overall health status.

    Objectives: Urinary incontinence (UI) is common among pregnant women. This growing health problem affects physical, emotional, and social well-being. This study determined the prevalence of UI and associated factors, and evaluated screening needs.

    Methods: A total of 330 pregnant women visiting the antenatal clinic in Hospital Universiti Sains Malaysia (USM) were surveyed. Data were collected through a self-administered questionnaire and analysed with SPSS software version 22.0.

    Results: Overall, 84.5% (n = 279) of the pregnant women had experienced UI. Multiple logistic regression identified body mass index (BMI), presence of other illness, and consumption of coffee as major risk factors for UI. The majority of pregnant women preferred early screening for UI.

    Conclusion: A great majority of pregnant women in this study experienced UI. Higher BMI and the presence of other medical conditions are significant risk factors for UI and early screening is required. The need for universal education about UI and pelvic floor muscle exercise is warranted and can potentially prevent postnatal UI and UI later in life.

    Objectives: Weight gain remains an issue for contraceptive users due to the high prevalence of obesity. This retrospective study compares the weight gain between hormonal and non-hormonal contraceptive users in government health clinics in Kota Bharu, Kelantan, Malaysia.

    Methods: A total of 380 women who had used the same contraceptive method for at least twelve months were recruited in this study. Covariance analysis was done to compare the weight gain between hormonal and non-hormonal contraceptive users, while studying the same confounders [age, household income, number of pregnancies, and baseline body mass index (BMI)].

    Results: Hormonal methods were more commonly used. The mean weight gain among hormonal users (adjusted mean 2.85, 95% CI 2.45, 3.24) was significantly higher than non-hormonal users (adjusted mean 0.46, 95% CI -0.73, 1.65; p-value <0.001), after controlling for age, household income, number of pregnancies, and baseline BMI.

    Conclusion: The possibility of weight gain following the use of hormonal methods should be investigated and non-hormonal methods should be considered to prevent weight gain.

    There is an increasing trend in the number of bariatric surgeries performed worldwide, partly because bariatric surgery is the most effective treatment for morbid obesity. Sleeve gastrectomy (SG) remains the most common bariatric surgery procedure performed, representing more than 50% of all primary bariatric interventions. Major surgical complications of SG include staple-line bleeding, leaking, and stenosis. A leak along the staple-line most commonly occurs at the gastroesophageal junction (GOJ). From January 2018 to December 2018, our centre performed 226 bariatric procedures, of which, 97.8% were primary bariatric procedures. The mean age and BMI were 38.7±8.3 years and 44 kg/m2, respectively. Out of the 202 primary SG performed, we encountered two cases of a staple-line leak (0.99%). This is the first reported case series of SG leaks from the Southeast Asia region. A summary of their characteristics, clinical presentation, subsequent management, and the outcome is discussed. Based on the latest available evidence from the literature, several methods may decrease staple-line leaks in SG. These include the use of a bougie size greater than 40 Fr, routine use of methylene blue test during surgery, beginning transection at 2-6 cm from the pylorus, mobilising the fundus before transection, and staying away from the GOJ at the last firing. Other methods include the proper alignment of the staple-line, control of staple-line bleeding, and performing staple-line reinforcement. The management of a staple-line leak remains challenging due to limited systematic, evidence-based literature being available. Therefore, a tailored approach is needed to manage this complication.

    In Malaysia, breakfast is the most frequently skipped meal. Skipping breakfast has been
    associated with an increased risk of childhood obesity. However, this relationship has not been
    investigated widely among preschoolers in Malaysia. Hence, this cross-sectional study aimed to
    determine the association between breakfast intake and Body Mass Index (BMI) among
    preschoolers in Taska Permata Keluarga (TPK), Kuala Nerus. A total of 131 Malays preschoolers
    aged four to six years old were recruited from nine TPK using convenience sampling method.
    Information on sociodemographic, breakfast intake pattern and anthropometric measurements
    (weight and height) were obtained. Respondents consisted of 74 (56.5%) boys and 57 (43.5%)
    girls. Anthropometric results showed that 8.4% preschoolers were overweight and obese. Among
    the preschoolers, 22.1% of them were breakfast skippers. In terms of gender breakdown, 20.3%
    boys and 24.6% girls skipped breakfast. There was a significant association between breakfast
    intake and BMI status among preschoolers (p = 0.003). This indicated that preschoolers that
    skipped breakfast were associated with overweight or obese compared to those who consumed
    breakfast daily. Breakfast consumption is a marker of a healthy lifestyle which can reduce the risk
    of childhood obesity. This habit should be inculcated during this critical period of life in which
    parents play a vital role in promoting breakfast consumption among preschoolers.

    Background: School children are at great risk of nutrition-related chronic diseases. Their eating pattern in
    school is influenced by the availability of food served within the school environment. The purpose of this
    paper was to determine the effectiveness of a canteen-based food nutrition intervention, designed according
    to the theory of planned behaviour, on the knowledge, perception and choices of healthy food among primary
    schoolchildren.
    Methods: This was a prospective intervention study using a two-group design. Six school canteens from the
    ninety-eight primary schools were randomly allocated to an intervention group or a control group. All the
    food handlers in the intervention group were given a twelve-week training course in food nutrition. On the
    completion of the course, 293 Standard Six students from these schools, were interviewed with a nutritional
    questionnaire on food in their school canteens. The training programme for the intervention group and the
    questionnaire for the students were developed and validated for the study, and a power calculation made for
    the sample size of students.
    Results: The students in both groups were homogeneous in gender and body mass. The mean body mass
    index (BMI) was 19.26 (SD: 0.38) and 19.47 (SD: 0.39) for the intervention and the control group respectively.
    There were more schoolchildren in the intervention group who purchased foods in school canteens (p 0.0036)

    Loss of teeth can affect masticatory efficiency in older adults. This may result in avoidance or modifications in food
    choices and lead to lower intake of important nutrients among older individuals. The aim of this study was to determine
    the association between tooth loss and body mass index, BMI, among older adults in Kuala Pilah, Negeri Sembilan. A
    cross-sectional study was carried out on 428 older adults aged 50 years and above from selected villages in district of
    Kuala Pilah. Respondents were interviewed to collect information on their demographic characteristics. Number of tooth
    loss was determined through oral assessment, followed by anthropometric assessment to calculate the BMI of respondents.
    Findings showed that majority of the respondents were overweight and obese, 40.4% and 19.9% respectively, while only
    a small proportion was underweight, 3.9%. The proportion of edentulism (total tooth loss) was 18.3% and majority of
    the older adults had lost more than 12 teeth (77.1%) and less than 4 pairs of occluding posterior teeth (86.0%). Total
    and partial tooth loss was found to be not significantly associated with BMI. In relation to the arrangement of teeth,
    older adults with reduced number of posterior occluding pairs of teeth were more likely to experience unsatisfactory
    BMI (OR = 3.61, 95% CI: 1.48, 8.76). This may suggest that functional arrangement of the tooth in the oral cavity is more
    important than the number of tooth loss alone. Thus, maintaining an optimum number of teeth for chewing is essential
    for maintenance of ideal BMI.

    Objectives: Overweight and obesity are known to cause various patterns of alteration to the pulmonary function test (PFT) parameters. We sought to investigate gender differences in PFT parameters and examine the relationship between body mass index (BMI) and PFT parameters.
    Methods: We conducted a retrospective study of 126 patients referred for a PFT by various medical specialties between January and December 2015. PFT was measured using spirometry, and BMI was calculated using Quetelet's index.
    Results: Female patients exhibited lower mean values for all PFT parameters compared to male patients. The forced vital capacity (FVC)% predicted was less than 80% for all patients while the ratio of forced expiratory volume in 1 second (FEV1)/FVC was higher with increased BMI. BMI was positively correlated with peak expiratory flow in all patients, and with FEV1/FVC ratio in males but not in females.
    Conclusions: In our studied population, males exhibited higher mean values of PFT parameters than females. Increased BMI may be associated with a restrictive pattern on spirometry.

    BACKGROUND: The 'Eat Right, Be Positive About Your Body and Live Actively' (EPaL) intervention programme was developed to prevent overweight and disordered eating in Malaysian adolescents. This study aimed to evaluate the effectiveness of the EPaL programme on knowledge, attitudes and practices on healthy lifestyle and body composition (body mass index z-score [zBMI], waist circumference [WC] and body fat percentage [BF%]) among adolescents.

    METHODS: All measures were taken at three time points: before intervention (Pre), after intervention (Post I) and 3 months after intervention (Post II). The intervention group (IG) participated in the EPaL programme for 16 weeks, whereas the comparison group (CG) received no intervention. Seventy-six adolescents (IG: n = 34; CG: n = 42) aged 13-14 years were included in the final analysis. Repeated measures analysis of covariance (ANCOVA) was used to assess the impact of the EPaL intervention programme on the measures between groups (IG and CG) at Post I and Post II.

    RESULTS: The IG reported significantly higher knowledge scores at both Post I (adjusted mean difference = 3.34; 95% confidence interval [CI] = 0.99, 5.69; p = 0.006) and Post II (adjusted mean difference = 2.82; 95% CI = 0.86, 4.78; p = 0.005) compared with the CG. No significant differences between the IG and CG were found at either Post I or Post II in attitudes, practices, zBMI, WC and BF%. The proportion of participants who were overweight or obese was consistent from Pre to Post II in the IG (35.3%) and increased from 26.2% at Pre to 28.5% at Post II in the CG, but the difference was not statistically significant. The proportion of participants who had abdominal obesity in the IG decreased from 17.6% at Pre to 14.7% at Post II and increased from 16.7% at Pre to 21.4% at Post II in the CG, but the differences were not statistically significant.

    CONCLUSION: Despite no significant reduction of body composition, this programme shows the positive effect on the adolescents' knowledge regarding healthy lifestyle. This study contributes to the evidence on the effectiveness of school-based health interventions in Malaysian adolescents.

    The aim of this study is to investigate the relationship between brown adipose tissue (BAT) activation and myocardial fluorine-18-fluorodeoxyglucose ([18F] FDG) uptake in terms of intensity and patterns. The patients were divided into two groups as follows: BAT and control groups. The BAT group consists of 34 cases that showed BAT uptake. The control group, with no BAT uptake, included 68 patients who were matched for body mass index, gender, and season. The scans were retrospectively reviewed by two nuclear medicine physicians who visually evaluated the intensity of myocardial [18F] FDG uptake. The myocardial [18F] FDG uptake was visually classified into the following three patterns: diffuse, heterogeneous, and focal. The regions of activated BAT distribution were noted. The mean myocardial [18F] FDG uptake was 2.50 ± 0.75 for the BAT group and 2.13 ± 0.88 for the control group with a statistically significant difference (P = 0.031). The myocardial [18F] FDG uptake pattern was similar in the BAT and control groups with the diffuse pattern being the most common, followed by the heterogeneous and less commonly focal. In the BAT group, the anatomical distribution of BAT was mainly in supraclavicular, paravertebral, and axillary and to a lesser extent in cervical regions. BAT group had a significantly higher intensity of [18F] FDG myocardial uptake compared to that of the control group. The presence of activated BAT did not affect the pattern of myocardial uptake. Knowledge of these findings may help in understanding the variability of myocardial [18F] FDG uptake and consequently in avoiding misinterpretation of cardiac findings in positron-emission tomography/computed tomography studies.

    The purpose of this study was to evaluate the image quality and diagnostic accuracy of coronary computed tomography angiography (CCTA) using 640-slice scanner. Advancement of multidetector computed tomography (MDCT) technology with higher spatial, temporal resolution, and increasing detector array have improved the image quality and diagnostic accuracy of CCTA. A total of 25 patients (12 men and 13 women) underwent CCTA examination was chosen and data was acquired by 640-slice scanner. All 16 segments of coronary arteries were evaluated by two reviewers using a 4-likert scale for qualitative assessment. In quantitative assessment, the evaluation of 4 main coronary arteries were analysed in terms of signal intensity (SI), image noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR). All 25 patients with a mean age of 52.88 ± 14.75 years old and body mass index (BMI) of 24.24 ± 3.28 kg/m2 were analysed. In qualitative assessment, from the total of 400 segments, 379 segments (95%) had diagnostic value while 21 segments did not have diagnostic value, which means 5% artefact was detected. In quantitative assessment, there was no statistical differences in gender, race, and BMI (p>0.05). Overall evaluation showed that higher SI at the left main artery (LM) at 393.7 ± 47.19. Image noise was higher at right coronary artery (RCA) at 39.01 ± 13.97. SNR and CNR showed higher at left anterior descending (LAD) with 12.73 ± 5.17 and LM 9.14 ± 4.2, respectively. In conclusion, this study indicates that 640-slice MDCT has higher diagnostic value in CCTA examination with 95% vessel visibility with 5% artefact detection.
