<p><strong>BACKGROUND:<em> </em></strong>There is considerable disagreement over the effects of percutaneous coronary intervention (PCI) on left ventricular diastolic function that has necessitated the investigation of diastolic indices. The present study was conducted to evaluate left ventricular diastolic function and its indices, three months after performing the PCI procedure in patients with coronary artery disease (CAD).</p> <p><strong>METHODS:<em> </em></strong>In a quasi-experimental clinical trial study (before and after), 51 patients with CAD scheduled for elective PCI were investigated provided that their Ejection Fraction (EF) was &gt; 30%. Before and three months after PCI, echocardiography was carried out to evaluate left ventricular diastolic indices including the E/Ea as the most important criteria for diagnosis of diastolic heart failure (DHF).<strong></strong></p> <p><strong>RESULTS:<em> </em></strong>Based on the E/Ea indices and after PCI, the number of patients with DHF decreased significantly: 40 patients (78.4%) before PCI versus 28 patients (54.9%) after PCI (p&lt;0.05). The Mean and Standard error of deceleration time (DT), isovolumic relaxation time (IVRT), early diastolic mitral annulus velocity; Ea (E'), E/Ea and left ventricular ejection function (LVEF) indices underwent significant changes. In addition, MVA dur/PVA dur, PVs/PVd, and E/Ea indices had changed significantly after PCI in both genders. However, no significant difference was reported for the other indices.</p> <p><strong>CONCLUSION:<em> </em></strong>The E/Ea ratio as an important criterion for diagnosis of DHF was improved after PCI. Improvement of several other diastolic indices was observed after the PCI procedure. It can be concluded that PCI can be an effective treatment modality in patients with left ventricular diastolic indices.</p>

Abstract Background Successful recanalisation of percutaneous coronary intervention for chronic total occlusion lesions has been associated with improved survival. Purpose This study aimed to assess the impact of successful percutaneous coronary intervention for chronic total occlusion lesions on the long-term outcome of patients with impaired and preserved left ventricular ejection fraction (LVEF). Methods The study sample consisted of 842 consecutive patients (928 chronic total occlusion lesions) undergoing percutaneous coronary intervention at our institution between October 2005 and December 2009. We divided them into 3 groups by the degree of LVEF: less than 40% (severely reduced LVEF, n=140), 40% to 59% (moderately reduced LVEF, n=470), and 60% and above (normal LVEF, n=232). We evaluated mortality during the 10-year follow-up period the basis of procedural success and failure. Results The overall procedural success rate was 89.1%. Median follow-up duration was 7.9 years. The 10-year cumulative incidences of cardiac death in each degree of LVEF are shown in the Figure. Conclusions Successful recanalisation for chronic total occlusion lesions in patients with impaired LVEF may be associated with reduced cardiac mortality.
