GENDER DIFFERENCES IN LEFT VENTRICULAR MASS IN HEALTHY ADULTS AFTER INDEXING FOR BODY SIZE

Abstract

Objective: The study was conducted to demonstrate the gender distribution of echocardiography based LV mass in healthy adults after indexing for body surface area (BSA) and height. Methodology: The study group consisted of 1137 healthy subjects on the basis of clinical assessment, electrocardiography and X-ray. LV mass values were calculated from standard parasternal long-axis M-mode echocardiographic readings. The LV mass values were then indexed for body size parameters in terms of BSA and body height.Gender based comparisons were carried out for LV mass after indexing for BSA and body height. Results: The study included 1137 adults including 53% males and 47% females. Mean body surface area was higher for males than females (1.7 ± 0.19vs 1.5 ± 0.15 m2). Mean height was higher for males (1.7 ± 0.08 vs 1.5 ± 0.06 m). Mean LV mass was 127.39 ±36.18SD in males and 104.95 ± 29.06 SD in females with P value of <0.05. Conclusion: Males have greater LV mass as compared to females independent of respective body sizes.
