Abstract
Objective: To comment on changes in left ventricular mass index and related factors in patients with aortic valves replacement for aortic stenosis at 108 Military Central Hospital. Subject and method: 67 patients underwent aortic valves replacement for aortic stenosis. Descriptive study, no control with variables: LVMI, probability of LVMI returning to normal after surgery, R analysis of correlation factors such as hypertension, diabetes, PPM... Result: LVMI decreased significantly after surgery with p<0.05. The estimated probability of LVMI returning to normal at month 24 was 55%, month 48 was 37.9%. LVMI (medium - term follow-up) was linearly correlated with preoperatively (r = 0.44, p<0.001). Hypertension and PPM significantly affected LVMI with R² = 0.244 and LVMI group to normal by 3.62 times compared with hypertensive group (p<0.05). Conclusion: After valve replacement LVMI decreased over time, the probability of LVMI returning to normal was closely related to preoperative LVMI, hypertension and PPM.
