ABSTRACT

Introduction: Exercise may be good for the heard but good diastolic function also appears to protect the capacity for exercise researchers found. Objectives: To correlate exercise capacity with the left ventricle diastolic function. Material and methods: The Study was conducted on 100 subjects at Haldiram and Moolchand Heart Centre, PBM Hospital, S.P. Medical College, Bikaner. First a resting echocardiography was performed to evaluate cardiovascular diastolic function. After echocardiography the subjects were underwent Bruce protocol treadmill test. Results: Diastolic dysfunction was strongly and inversely associated with exercise capacity. Compared with normal function, those with resting diastolic dysfunction had substantially lower exercise capacity. Conclusion: Left ventricular diastolic function were independently associated with exercise capacity.

ABSTRACT

Pulsed wave Doppler echocardiograpdy was performed in eighteen cases with chronic mitral regurgitation(CMR)and 21 normal individuals td detect the quantitative changes of the mitral diastolic flow spectrum.The results showed that the pseudonormalization of mitral flow spectrum in CMR was actually caused by impaired left ventricle(LV)active relaxation and decreased LV compliance:It thus masked the LV diastolic dysfunction in CMR.E-wave pressure gradiant(E-PG),A-wave pressure gradiant(A-PG),isovolumic relaxation time(IVRT),E deceleration time(E-DT)and LV filling time(LVFT)in CMR group were significantly different in from those in normal group(P<0.01).Therefore it is essential to integrate these parameters as the indexes to evaluate the LV diastolic dysfunction in CMR.

ABSTRACT

Objective To study the changes in echocardiography in normotensive patients with type2 diabetes mellitus (T2DM) in order to establish early diagnosis and give preventive measures for diabetic cardiomyopathy (DCM). Methods Microvasculopathy was diagnosed in T2DM patients when microalbuminuria exceeded 15ml/min. Fifty-four T2DM patients were divided into two groups: group A (patients without microvasculopathy, n=32 ), group B (patients with microvasculopathy, n=22). All of T2DM were submitted to echocardiography and the results were compared with healthy people of matched sex and age (group C, n=20). Results There were no differences in systolic function parameters among the groups. Left ventricular mass index (LVMI) was higher in two groups of diabetics compared with group C. Diastolic dysfunction of various degrees was found in the two groups of diabetics, regardless of the presence of microvasculopathy, with a manifestation of a decrease of blood flow velocity in early diastolic phase and increase in late diastolic phase (P
