Abstract

ABSTRACT:
BACK GROUND:
With respect to cardiovascular performance at rest and exercise, diastolic function is of equal
importance to systolic function, which is the ability of the ventricle to fill at low left atrial pressure and
diastolic HF have hospitalization rates similar to those with systolic dysfunction
OBJECTIVE:
To assess the effect of successful coronary revascularization on segmental LV diastolic dysfunction and
the effect of this segmental improvement on global diastolic function.
METHODS:
patients with diastolic LV dysfunction and ischemic heart disease that are documented by coronary
angiography were selected randomly in a prospective interventional study at Ibn Al-Bitar Hospital For
Cardiac Surgery from June 2012 till April 2013 and followed up to one month post coronary
revascularization with Doppler echo-parameters and tissue myocardial velocities for any Improvement
in global or regional diastolic dysfunction.
RESULTS:
Twenty nine ischemic left ventricular segments of total 43 segments with diastolic dysfunction showed
improvement in diastolic function one month after successful revascularization.
CONCLUSION:
Segmental diastolic dysfunction can be improved with revascularization of the stenotic coronary artery
supplying that segment.
