Evaluation of the Impact of Blood Pressure Level on the Left Ventricle Movement of Hypertension Patients with Tis-sue-doppler Imaging
摘要
Abstract
Objective To evaluate the impact of blood presure control level on the left ventriclemovement and structure remodeling of the hypertension patients with tissue-doppler imaging. Methods Forty hypertension patients(20 with standard blood pressure level and 20 with substandard level ) and 20 healthy subjects were enrolled and both pulse-doppler and tissue-doppler im-aging were adopted to evaluate the structure and movement of the left ventricle. Results There was a significant difference in the left ventricle structure and diastolic function between hypertension patients and the healthy subjects(P<0. 05),and hypertension patients with substandard blood pressure level suffered a lowerearly diastolic velocities( Ve ) and late diastolic velocities( Va ) com-paring with the ones with standard blood pressure level in the different segments of left ventricle, besides, the ratio of Ve/Va was also distinctively different between the two groups of patients. Conclusion Blood pressure level impacts left ventricle diastolic function significantly and well-controlled blood pressure that may help to postpone the left ventricle remodeling and diastolic dis-function in hypertension patients.关键词
