Title: Cardiac Arrest Caused by Heart Attack Cardiac arrest, otherwise known as cardiopulmonary arrest or circulatory arrest, is the end of normal circulation of the blood due to failure of the heart to contract effectively. Medical personnel may refer to an unexpected cardiac arrest as a sudden cardiac arrest (SCA). Cardiac arrest occurs when the heart malfunctions and stops beating unexpected. It is loss of heart function. As the name implies, Cardiac Arrest is instantaneous and most individuals become unconscious within seconds to minutes as a result of insufficient cerebral blood. Underlying heart disease is present the vast majority of patients with Cardiac Arrest. On the other hand, Myocardial infarction (MI) or acute myocardial infarction (AMI), commonly known as a heart attack, results from the partial interruption of blood supply to a part of the heart, causing heart cells to die. This is most commonly due to occlusion (blockage) of coronary artery following the rupture of a vulnerable astheroletic plaque which is an unstable collection of lipids(cholesterol and fatty acids) and white blood cells (especially macrophages) in the wall of an artery. The resulting ischemia (restriction in blood supply) and ensuing oxygen shortage if left untreated for a sufficient period of time, can cause damage or death (infarction) of heart muscle tissue (myocardium). Cardiac Arrest is an “electrical“ problem while Heart Attack is a “circulation“ problem. Sudden cardiac arrest is not a (myocardial infarction) heart attack, but can occur during a heart attack. Heart attacks occur when there is a blockage in one or more of the arteries to the heart, preventing the heart from receiving enough oxygen-rich blood. If the oxygen in the blood cannot reach the heart muscle, the heart becomes damaged, or the part of the heart that does not receive oxygen and nutrients becomes
