Abstract
CVD is responsible for about 30% of all deaths worldwide each year. Of note, nearly 80% of these deaths occur in low- and middle-income countries, and half occur in women. (2)The World Health Organization (WHO) has estimated that
by 2030, the global number of deaths from IHD will have risen from 7.4 million in 2012 to 9.2 million.(4)Imaging techniques based on perfusion, metabolism or wall motion are more sensitive than an ECG or symptoms in detecting ischemia; this sequence is explained by the ischemic cascade. (5)Two-dimensional echocardiography is a sensitive,inexpensive, and readily accessible noninvasive technique that is capable of visualizing abnormal left ventricular wall motion in patients with acute and chronic ischemic heart syndromes.(19)Revascularization (surgical or catheter-based) should be considered if ischemic symptoms persist after intensification of medical therapy, including stringent risk factor modification, or if unacceptable side effects limit anti-anginal therapy. (62)The four major determinants of risk in CAD are the extent of ischemia, number of vessels diseased, LV function, and electrical substrate The extent of ischemia on noninvasive testing is an important predictor for subsequent adverse outcomes and identifies patients for whom revascularization may provide clinical benefit compared with medical therapy beyond the relief of symptoms. (64)PCI, which includes percutaneous transluminal coronary angioplasty (PTCA), stenting, and related techniques, has continued to evolve significantly over the past three decades.(66)The present study was aimed at determining the effect of elective percutaneous coronary intervention on segmental wall motion abnormality our target also was to assess both systolic and diastolic myocardial function, following blood flow restoration in patients with chronic coronary syndrome on maximal medical treatment or had a previous history of MI.Our study was conducted on fifty patients suffering from chronic stable angina and on maximal medical treatment or had a previous history of MI who underwent coronary angiography that yielded a single significant or multi-vessel disease.
