Risk factors for ventricular tachycardia in acute ST-elevated myocardial infarction patients of a tertiary care hospital of Peshawar

Abstract

Myocardial ischemia can occur because of high metabolic demand of cardiac tissue, less supply of nutrients and oxygen to the tissue through coronary dissemination, or both. Thrombus formation in coronary arteries and consequent occlusion compromises the inflow of oxygen and other nutrients. Myocardial infarction (MI) is classified based on diagnostic criteria into ST-Elevation Myocardial Infarction (STEMI) and non-STsegment Elevation Myocardial Infarction (NSTEMI) due to the ECG appearance of elevated or non-elevated ST-segment. MI is the leading cause of death in the USA and other developed countries; almost 450,000 people die in the USA per year due to MI, with a survival rate of 95% in hospitalized patients. Identified significant risk factors for non-fatal MI in patients with STEMI and NSTEMI included sexual orientation, increasing age, high blood pressure, diabetes mellitus, dyslipidemia, tobacco use, chronic obstructive pulmonary disease and family history of atherosclerotic illness.
