MYOCARDIAL INFARCTION Myocardial infarction (MI) or acute myocardial infarction (AMI)‚ commonly known as a heart attack‚ is the interruption of blood supply to part of the heart‚ causing heart cells to die. This is most commonly due to occlusion (blockage) of a coronary artery following the rupture of a vulnerable atherosclerotic plaque‚ which is an unstable collection of lipids (fatty acids) and white blood cells (especially macrophages) in the wall of an artery. The resulting ischemia (restriction
Premium Myocardial infarction
A heart attack‚ also known as a myocardial infarction‚ usually occurs when a blood clot forms inside a coronary artery at the site of an atherosclerotic plaque. The blood clot severely limits or completely cuts off blood flow to part of the heart. In a small percentage of cases‚ blood flow is cut off when the muscles in the artery wall contract suddenly‚ constricting the artery. This constriction‚ called vasospasm‚ can occur in an artery that is only slightly narrowed by atherosclerosis or even in

Various genetic‚ social economic and environmental factors increase the risk of AMI. This essay covers CVD in Australia‚ the major modifiable and non-modifiable risk factors that cause AMI.

MYOCARDIAL INFARCTION This term refers to the death of a certain segment of the heart muscle (myocardium)‚ usually the result of a focal complete blockage in one of the main coronary arteries or a branch thereof. The main cause of myocardial infarction is atherosclerosis in the coronary arteries. Refer to figure 70 for the pathogenesis of myocardial infarction. This event results in impaired contractility of the heart muscle within seconds‚ and is initially restricted to the affected segment.

MICHAEL MENSAH FELBRY COLLEGE SCHOOL OF NURSING ANATOMY AND PHYSIOLOGY 102 MYOCARDIAL INFARCTION INTRODUCTION Myocardial infarction is the technical name for a heart attack. A heart attack occurs when an artery leading to the heart becomes completely blocked and the heart does not get enough blood or oxygen‚ causing cells in that area of the heart to die (called an infarct). Most heart attacks are caused by blood clots‚ which are in turn caused

The Pathology of Myocardial Infarction The heart is considered one of the most vital organs for human survival and is responsible for giving human life and pumping blood through the arteries‚ capillaries‚ and veins. Heart diseases make the heart function improperly which causes the blood to not circulate throughout the body‚ making human life impossible. Heart diseases is considered to be number one on the top ten lists of death in the world. Because of this reason‚ I believe that understanding

MYOCARDIAL INFARCTION AND THE AGING ADULT Acute Coronary syndrome (ACS) is an emergent situation characterized by an acute onset of myocardial ischemia that results in myocardial death (i.e.‚ MI) if definitive interventions do not occur promptly. (Although the terms coronary occlusion‚ heart attack‚ and myocardial infarction are used synonymously‚ the preferred term is myocardial infarction.) The spectrum of ACS includes unstable angina‚ NSTEMI‚ and ST-segment elevation of myocardial infarction

PATHOPHYSIOLOGY OF MYOCARDIAL INFARCTION Mechanisms of Occlusion Most MIs are caused by a disruption in the vascular endothelium associated with an unstable atherosclerotic plaque that stimulates the formation of an intracoronary thrombus‚ which results in coronary artery blood flow occlusion. If such an occlusion persists long enough (20 to 40 min)‚ irreversible myocardial cell damage and cell death will occur.5 The development of atherosclerotic plaque occurs over a period of years to decades
