Abstract
Introduction: Ischemic heart disease is one of the major causes of death, disability and health care resource utilization worldwide. The prevalence of severe ischemic LV disease is progressively increasing due to the common use of thrombolytic therapy, angioplasty and stenting, and postponing surgical treatment until coronary artery disease progresses.
Coronary artery bypass grafting (CABG) is a common procedure to treat coronary artery disease (CAD) at all ages. it is carried out to prolong life expectancy as it improves long term survival .it significantly improves symptoms of angina, exercise capacity and reduce the need for medications, overall quality of life improves.
Aims: The purpose of this study is to improve the outcome of coronary artery bypass grafting in patient with impaired left ventricular function.
Summary: In last, we can summaries the following results regarding CABG in patients with impaired LV function:
Ischemic heart disease is a major health problem; it is the result of an imbalance between myocardial oxygen supply and demand. Coronary atherosclerosis is the dominant underlying cause of ischemic heart disease.
In the last several decades the number of the patients with impaired left ventricular ejection fraction (EF) due to ischemic heart disease has increased as a result of progressively aging population and expanded and repeated usage of PCI in coronary revascularization and delayed surgical option.
