Diagnostic significance of left ventricular mass index and left cardiac function in patients with hy-pertensive heart disease by ultrasonic cardiogram

Abstract

Objective To investigate the diagnostic value of left ventricular structure and func-tion on patients with hypertensive heart disease（HHD）by ultrasonic cardiography（UCG）,in order to provide the basis for early diagnosis and treatment. Methods Fifty patients with HHD were chose as ob-servation group,and 50 healthy people as control group. Using Philips Sonos 5500 ultrasound apparatus, the transducer frequency was 2. 0 - 4. 0 MHz,the left ventricular ejection fraction（LVEF）,left ventric-ular end systolic volume（LVESV）,left ventricular end-diastolic volume（LVEDV）,left ventricular my-ocardial quality（LVMM）,the ratio of E peak and A peak of mitral orifice end diastolic velocity,the left atrium diameter（LAD）,and other indicators were detected. Results The difference of left cardiac sys-tolic function between the two groups was not significant（P 〉 0. 05）;LVEDV,LVMM,LAD in observa-tion group was higher than that in control group,the difference was significant（P 〈 0. 05）;E / A,LVEF in observation group was lower than that in control group,the difference was statistically significant（P 〈0. 05）. In observation group,LVEDV,LVD,LVEF,E / A showed Ⅲ period 〉 Ⅱ period 〉 Ⅰ period. LVEDV,LVD was positively correlated with blood pressure value,E / A,LVEF was negatively correlated with blood pressure values. Conclusions UCG can accurately determine the area of the left atrial en-largement or the degree of left ventricular hypertrophy,objective evaluation of cardiac function,and pro-vide a basis for early diagnosis,treatment and prognosis evaluation of HHD.
