<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>

Echocardiographic Parameters

Background: Left ventricular (LV) diastolic dysfunction occurs before LV systolic dysfunction and electrocardiographic changes in ischemic cascade. Diastolic wall strain (DWS) has been proposed as a marker of LV diastolic stiffness. Therefore, the objectives of this study were to defined the relationship between DWS and percutaneous coronary intervention (PCI) and see other echocardiographic parameters in patients who undergoing coronary angiography (CAG). Methods: 254 patients (mean age: 61 ± 10, 136 (54%) men) undergoing CAG and normal left ventricular systolic function without regional wall motion abnormalities were enrolled, and among them, 68 (27%) patients performed PCI. All patients performed echocardiography before CAG and DWS defined using posterior wall thickness (PWT) measurements from standard echocardiographic images (DWS =[PWT(systole)-PWTdiastole)]/PWT(systole)). Results: Patients who performed PCI showed significantly lower DWS (0.27 ± 0.09 vs. 0.39 ± 0.08, p < 0.001). Age did not differ between the two groups (61.6 ± 10.6 vs. 60.9 ± 10.4, p = 0.623), and LV ejection fraction was also similar (62.8 ± 4.6 vs. 63.5 ± 5.2%, p = 0.380). Other echocardiographic parameters did not show significance differences but E/E’ ratio was slightly but significantly elevated in patients performed PCI (10.9 ± 4.8 vs 9.2 ± 3.3, p = 0.011). In multiple regression analysis, lower DWS was an independent predictor for PCI (Cut-off value: 0.34, sensitivity: 89%, AUC: 0.870, SE: 0.025, p < 0.001). Conclusion: DWS, a simple parameter that can be calculated from routine 2D echocardiography, is inversely associated with presence of coronary artery disease and PCI.
