AIM: To determine the direct effect of obesity on echocardiographic indices of diastolic left ventricular function METHODS: 44 obese (BMI > or =25 kg/m2) and 45 normal weight women were studied. They had no other pathological conditions. Echocardiographic indices of diastolic function were obtained, and dysfunction was assumed when at least two values differed by > or =2 SD from the normal weight group. RESULTS: In obese subjects, the values of maximum velocity of active mitral filling (A) were increased and pulmonary diastolic velocity was decreased significantly (p< 0,01); all other diastolic variables were unchanged. Subclinical diastolic dysfunction tend to be more prevalent among obese subjects but it was not significantly different from non obese (p= 0.11), being present in nine obese (20.5%) and 4 normal (8.9%) subjects. CONCLUSION: Subclinical left ventricular diastolic dysfunction is present in obese women.

The correlation between insulin resistance and left ventricular systolic function in obese women.

AIM: To determine the correlation between insulin resistance and left ventricular systolic function in obese women. METHODS: 44 obese (BMI > or =25 kg/m2) and 45 normal weight women were studied. They had no other pathological conditions. Echocardiograms were undertaken in our echocardiographic laboratory following standard methods. The homeostasis model was used to assess insulin resistance (HOMA IR). RESULTS: Ejection fraction (p =0.22) and fractional shortening (p= 0.58) were not difference between obese women and the normal group. There was no correlation between insulin resistance and left ventricular systolic function. CONCLUSION: There was no correlation between insulin resistance and left ventricular ejection fraction.

Correlation between left ventricular mass and visceral fat thickness in obese women.

AIM: This study was aimed to measure left ventricular mass, which partly determines the function of the left ventricle, in obese women. METHODS: The total number of study subjects was 90, which consisted of 45 obese women (BMI >or= 25 Kg/m2) and 45 non-obese women (BMI < 25 Kg/m2) as control group. They were evaluated by M mode echocardiography and abdominal CT to measure visceral fat, blood pressure, insulin resistance and waist circumference. Correlation was assessed for both groups. RESULTS: There were significant differences in the left ventricular mass of the obese and non-obese group (P= 0.000), systolic blood pressure (P = 0.000), diastolic blood pressure (P = 0.006), waist circumference (P = 0.000), visceral fat (P = 0.000), and HOMA-IR (P = 0.000). With bivariant analysis, it is concluded that there are significant correlations between left ventricular mass and visceral fat (r = 0.67, P = 0.000); between BMI and left ventricular mass (r = 0.67, P = 0.000); between waist circumference and left ventricular mass (r = 0.72, P = 0.000); and also between HOMA-IR and left ventricular mass (r = 0.57, P = 0.000). CONCLUSION: There are significant correlations between increased left ventricular mass and visceral fat, BMI, waist circumference and HOMA-IR among Indonesian women. So far, this study has shown a correlation between obesity and high cardiovascular risk.
