Abstract

Abstract:
Aims: to evaluate the effect of percutaneous coronary intervention (PCI) on diastolic function in patients with known coronary artery disease (CAD).
Methods: 51 patients who were candidates for PCI because of CAD; with left ventricular ejection fraction>30% and any degree of diastolic dysfunction (grade 1-4) and no left ventricular hypertrophy (LVH), uncontrolled hypertension (resting blood pressure>140/90 mm hg), Atrial fibrillation rhythm, hypertrophic cardiomyopathy, elevated Cr level, bundle branch or complete heart block, severe ventricular arrhythmias, severe valvular heart diseases, cardiac pacemakers and or prior coronary artery bypass graft surgery; preexamined by transthoracic echocardiography and diastolic indexes such as Isovolumic relaxation time (IVRT); Deceleration Time (DT); Transmitral flow velocity with atrial contraction duration/Flow from left atrium to pulmonary veins during atrial contraction duration (MVA dur/PVA dur); Early diastolic transmitral flow velocity/Velocity of early diastolic mitral annular motion(E/Ea); Pulmonary vein systolic flow/Pulmonary vein diastolic flow (PVs/PVd); Early diastolic transmitral flow velocity/Transmitral flow velocity with atrial contraction (E/A) and Ea were measured. Then patients underwent PCI. The diastolic indexes were reevaluated and recorded in forms three months after PCI and analyzed by statistic methods..
Results: As a result of PCI, a significant improvement was observed in the DT ( P
