A Comparative Study of Cardiac Function in Patients with Coronary Heart Disease and Hypertension by Strain Rate Imaging
摘要
Abstract
Objective To explore the clinical value of strain rate imaging( SRI )technology in comparing the left ventricular cardiac function in patients with coronary heart disease and hypertension. Methods Twenty-nine healthy volunteers were treated as control group( group A ), forty patients with coronary heart disease( group B )weredivided into two subgroups: group Bl( angina pectoris, n = 19 )and h myocardium infarction( group B2, n = 21 ),fifty-two patients with hypertension( group C )were divided into two groups according to ambulatory Blood pressure profiles : group C1( dippers )and group C2( nondippers ) , twenty patients with essential hypertension and coronary heart disease( group D ). The the peak systolic strain rate( PSSR )during systole were measured in all patients, the mean PSSR( mPSSR )were calculated. The numbers of post systolic deformation( PSS )segments were recorded and analyzed in the left ventricular walls. Results mPSSR of group B1 , B2, C1, C2 and D were significantly lower than that of group A , respectively( P<0. 05 ) ; mPSSR of group B2 was significantly lower than those of groups Bl and D;mPSSR of group D and C2 was significantly lower than that of group C1 , respectively( P<0. 05 ). The presentation of PSS. in the left ventricle of groups B and D were significantly lower than those of group A and C( P <0. 05 ),while the differences between group A and C as well as group B and D were not significant( P >0. 05 ). Conclusion SRI provides us a new and accurate method, to evaluate the left ventricular systolic function quantitatively in patients with coronary heart disease and hypertension.关键词
