Gender Differences on Echocardiography in Essential Hypertensives / 中华高血压杂志

ABSTRACT

Objective To study the gender differences in echocardiography in essential hypertensives. Methods Echocardiography measurement was performed in 108 subjects with Grade 1-2 essential hypertension (52 in female patient group, PGf, and 56 in male patient group, PGm). Forty two normotensive subjects (20 in female control group, CGf, and 22 in male control group, CGm) were as controls.Data were obtained by averaging measurements of the traced heart chambers and velocity curves in 5 cardiac cycles. Results Compared with PGm, the following echocardiographic features in PGf were showedLAID (37.24±5.88 vs 32.14±3.80)mm,P＜0.01] and MVa[(84.18±12.13 vs 81.71±12.30)cm/s, P＜0. 05] were greater; LVMI [ ( 119.26 ± 22.33 vs 128.17 ± 27.00 ) g/m2 , P＜0. 05], EF ( 75.13 % ±6.69% vs 83.00% ±3.68%,P＜0. 01), FS (41.67% ±7.99%0 vs 49.03% ± 7.35%, P＜0.01), MVe[(68. 28±8.66 vs 73. 73±11.46)cm/s, P＜0. 05] and MVe/a(0.83±0. 08 vs 0. 93±0.11, P＜0.01)were lower. The differences between CGf and CGm were not significant. Conclusion There are echocardiographic differences between sexes in hypertensives including cardiac structural and functional changes. Hypertensive woman is more susceptible to both cardiac structure damage and cardiac dysfunction.
