To study the echocardiographic features in female hypertensives.Methods Echocardiography was performed by using an HEWLETT PACKARD 5500 Sonographic Computer System and M-mode, 2-dimension, color imaging and pulsed-wave spectral Doppler in 30 females with I ~ E stage essential hyper tension (patient group, PG) and 30 age-matched normotensive females without heart diseases(control group, CG) .The data assessed were automatically calculated by using the Computer System via averaging the measured values of the traced velocity curves from 5 cycles. Data were expressed as x±SD. The t test and correlation analysis were used to analyse the data.Results Compared with CG, the following e-chocardiographic features in PG were shown: left atrial internal dimension (LAID) and left ventricular mass (LVM) were larger; EF slope(EFs) and fractional shortening (FS) were lower; mitrial valve (MVa) and tricuspid valve (TVa) were higher; MVe, MVe/a and TVe/a were lower. The significant results drawn from correlation
To study the echocardiographic features in female hypertensives.Methods Echocardiography was performed by using an HEWLETT PACKARD 5500 Sonographic Computer System and M-mode, 2-dimension, color imaging and pulsed-wave spectral Doppler in 30 females with I ~ E stage essential hyper tension (patient group, PG) and 30 age-matched normotensive females without heart diseases(control group, CG) .The data assessed were automatically calculated by using the Computer System via averaging the measured values of the traced velocity curves from 5 cycles. Data were expressed as x±SD. The t test and correlation analysis were used to analyse the data.Results Compared with CG, the following e-chocardiographic features in PG were shown: left atrial internal dimension (LAID) and left ventricular mass (LVM) were larger; EF slope(EFs) and fractional shortening (FS) were lower; mitrial valve (MVa) and tricuspid valve (TVa) were higher; MVe, MVe/a and TVe/a were lower. The significant results drawn from correlation analysis in PG showed that LAID, LVM were positively related to SPB;LVM was positively related to DBP and the duration of hypertension (HD); EF slope was negatively related to DBP; MVe/a and TVe/a were negatively related to SBP;LVM was negatively related to FS, EF slope and MVe/a; MVe/a was positively related to TVe/a.Conclusion There are certain features on the e-chocardiography in female hypertensives with cardiac structural and functional changes which are related to BP and HD. We also conclude from the correlation analysis that LVH is an independent risk factor for the cardiac systolic and diastolic dysfunctions which featured by that LVM related to FS, EF slope and MVe/a significantly.
