Relationship Between Myocardial Ischemia and Left Ventricular Diastolic Function by Fractional Flow Reserve Evaluation in Patients With Coronary Artery Disease / 中国循环杂志

ABSTRACT

Objective: To explore the relationship between myocardial ischemia and left ventricular diastolic function (LVDF) by fractional lfow reserve (FFR) evaluation in patients with coronary artery disease (CAD). Methods: A total of 57 patients with chest pain were studied, the diagnosis of CAD was confirmed by coronary angiography, which indicated 50%-70%of coronary stenosis. All patients received FFR examination and they were divided into 2 groupsExperimental group, the patients with FFR Results: The patients’ gender, age, history of hypertension, diabetes, blood levels of cholesterol, TG, LDL-C, HDL-C and glucose were similar between 2 groups, P>0.05. Compared with Control group, the Experimental group had the increased LVEDD, LAD and E/e ' value and decreased LVEF, all P Conclusion: The impact of CAD on early diastolic function depends on functional myocardial ischemia in relevant patients.
