Results: A total 34 patients was included in this study, in which 17 patients (50%), 13 patients (38%) and 4 patients (11%) belongs to the control group, low ABI group and very low ABI group respectively. The overall mean ABI is 0.93 with minimum and maximum ABI value is 0.71 and 1.31 respectively. There is signicant difference in the mean modied gensini score between the three groups (5.244.35 vs 13.623.31 vs 169.83 in control, low ABI and very low ABI respectively, P value <0.001). From Pearson correlation test, there is signicant corelation between ABI and modied gensini score ( r ¼ -0.612 and p value < 0.001). ABI <0.9 signicantly have higher odds of having severe coronary artery stenosis (modied gensini score >13), with odd ratio (OR) 9.07, P value 0.003. Low ABI (OR 8.67 P value 0.03) and very low ABI (OR 5.15 P value 0.023), both have a higher odds of having severe coronary artery stenosis compared to control. On multivariate logistic regression analysis, ABI remained an independent predictor of CAD severity after correcting for other conventional risk factors for CAD. Conclusion: ABI <0.9 have a higher risk to have severe coronary artery stenosis. Decreased ABI value associated with the increased of severity coronary artery stenosis. ABI is a simple and noninvasive method that can predict severity of coronary artery stenosis patient with coronary artery disease. This association is independent of other conventional cardiovas- cular risk factors.

It is also associated with diabetic cardiomyopathy of which the epidemiology is not well dened. We sought to study the pattern of cardiovascular risk factors in an asymptomatic diabetic population from Malaysia. Objectives: To assess cardiovascular risk factors in diabetic and pre-diabetic patients. Methods: Subjects were recruited as part of a community study on cardiovascular diseases between the years 2007 to 2011. Demographic details, cardiovascular risk factors along with echocardiogram were obtained. Results: A total of 1932 subjects with echocardiogram were analyzed. Mean age was 54.6 11.6. Majority of the subjects were male 98.3% (1899). Mean systolic ejection fraction (EF) was 64.5% 7.0. Prevalenve of diastolic dysfunction was 52.8% (1021). Of all the subjects with diastolic dysfunction, 29.9% (578) had impaired relaxation, 21.0% (406) pseudonormal and 1.9% (37) restrictive defect. Among subjects with diastolic dysfunction, 13.8% (266) were diabetic and 9.6% (185) were pre-diabetic (impaired fasting glucose). Table below summarize the cardiovascular risk factors among the subjects with diabetes and pre-diabetes. In univariate analysis only age and hypertension found to be signicant predictor for diastolic dysfunction among diabetes mellitus subjects. However in multi- variate analysis, age was the only the strong predictor for a diabetic patients to have dia- stolic dysfunction with OR 0.57 (CI:1.01-1.10). Conclusion: The prevalence of diastolic dysfunction in diabetic and impaired glucose tolerance subjects in our population was suprisingly higher than reported. Age and hy- pertension remain a signicant risk factor associated with risk of developing diastolic dysfunction in patients with diabetes mellitus, however after adjusted only age is the strong predictor.

Johan* 1 , Ibrahim Zubin 1 , Arshad Kamal 1 , Abd Rahman Effarezan 1 , Zainal Abidin Hasyatul 1 , Lim Chiao Wen 1 , Kasim Sazzli 1 1 Cardiology, UiTM, Sungai Buloh, Malaysia Introduction: The left atrium (LA) is a complex structure and is frequently involved in disease affecting the left ventricle. LA dilation is related to an increased lling pressure and is a strong predictor of heart failure, stroke and death. Assessment of LAVI in asymptomatic patients may help in aggressive risk factors control and prevent further complication as it is an inexpensive and readily available tool. Objectives: To describe LAVI in normal and diseased states in an asymptomatic Asian population. Methods: Between 2007 and 2011, subjects participating in a longitudinal population study looking at cardiovascular diseases were enrolled. Demographic data, cardiovascular risk factors and echocardiograph were obtained. LA volume was calculated by the area- length method in the apical 2-chamber and apical 4-chamber view and indexed to body surface area (BSA). Descriptive, univariate and multivariate analysis were performed using SPSS version 16. Results: A total of 1932 subjects with echocardiogram were analyzed. Mean age was 54.6 11.6. Majority of the subjects were male 98.3% (1899). Mean systolic ejection fraction (EF) was 64.5% 7.0. Majority was Malay ethnic 81.9% (1582), 13.8% (266) were di- abetics and 9.6% (185) had impaired fasting glocose (IFG). 60.6% (1170) had high LDL level of more than 3.4mmol/L. 26.1% (505) were hypertensive and 59.1% (142) were obese. Mean left atrial volume index was 28.0 9.1 ml/m 2 . Total of 40.3% (778) had LAVI > 28 ml/m 2 . For those with LAVI > 28 ml/m2, 12.6% (98) were in the healthy subjects while the remaining 87.4% (680) had at least 1 risk factor (diabetes, hypertension, dysli- pidemia or obesity). Table below summarized the prevalence of LAVI > 28 ml/m 2 in normal and disease subjects. For subjects with LAVI 28 ml/m 2 , hypertension, and live in urban area remained the strong predictors for LAVI > 28 ml/m 2 after univariate and multivariate analysis with age adjusted. Conclusion: Our ndings supported previous study that LAVI measurement is a potential tool to be used in assessment of asymptomatic patients with cardiovascular risk factors as these subclinical patients might benet from aggresive risk factor control to prevent further complication.

Objectives: We evaluated simultaneous vascular and metabolic responses to pravastatin and valsartan therapy, alone or in combination, in hypercholesterolemic patients. Methods: Forty-eight hypercholesterolemic patients (23 had metabolic syndrome) were given pravastatin 40 mg and placebo, pravastatin 40 mg and valsartan 160 mg, or valsartan 160 mg and placebo daily during each 2 month treatment period in a randomized, single- blind, placebo-controlled cross-over trial with three treatment arms and two washout periods (each 2 months). Results: Of note, brachial artery ow-mediated dilation improved to a greater extent with combined therapy vs. either monotherapy (P<0.001 by ANOVA). Interestingly, when compared with monotherapy, combined therapy signicantly reduced hs-CRP levels to a greater extent (P¼0.019 by ANOVA on Ranks). We also observed simultaneous improvement in metabolic phenotypes with all three treatments causing increased plasma adiponectin levels, reduced fasting plasma insulin levels, and increased insulin sensitivity (determined by QUICKI) relative to baseline measurements. For the rst time in a statin combination trial, pravastatin combined with valsartan therapy increased plasma adiponectin, lowered fasting insulin, and improved insulin sensitivity in an additive manner when compared with either monotherapy alone (P¼0.003, P¼0.049, and P¼0.049 by ANOVA on Ranks, respectively). Overall, we observed similar results in 23 patients with metabolic syndrome. Conclusion: Pravastatin combined with valsartan improved endothelial function and metabolic phenotypes in an additive fashion in patients with hypercholesterolemia or metabolic syndrome.
