Abstract:
Objective To evaluate the effects of impaired glucose tolerance (IGT) on ventricular remodeling. Methods Parameters of every subject including left ventricular mass ( LVM), left ventricular mass index (LVMI), E/A ratio, 75 g oral glucose tolerance test (OGTT), ambulatory blood pressure monitoring(ABPM) data including 24-hour mean systolic blood pressure(mSBP) and 24-hour mean diastolic blood pressure(mDBP) were collected. Then the relationship of IGT and myocardial remodeling related parameters were analyzed. Results The rate of diastolic dysfunction was higher in the IGT combined with hypertensive group(74% ) compared with the hypertensive group( 39% )( x2 = 6. 5, P ＜ 0. 05 ). The rate of diastolic dysfunction was higher in the IGT group( 34% ) compared with the normal group( 10% ) (x2 = 5.2,P ＜0. 05). The rate of Left Ventricular Hypertrophy (LVH)in the IGT combined with hypertensive group (24%) was higher than the other three groups (Hypertension group 7%, IGT group 0, Normal group 0) (x2 =4.561,P ＜0.05), and there was no significance between the rest three groups (P ＞0.05).Stepwise multiple regression showed age and 2 Hours' Postprandial Blood Glucose were independent risk factors of E/A ratio. Conclusions These results suggested that IGT is a possible contributor to left ventricular hypertrophy and diastolic dysfunction, and is one of the histopathology of left ventricular remodeling.
