heart attack

تعريف heart attack في الإنجليزية الإنجليزية القاموس.: An acute myocardial infarction caused by the sudden occurrence of coronary thrombosis, which obstructs the blood supply to the heart and leads to necrosis of heart muscle tissue. It is characterised by sudden severe chest pain often radiating to the shoulder, arm, or jaw, shortness of breath, nausea, and loss of consciousness, and is sometimes fatal; -A medical emergency that occurs when a blood clot forms suddenly in a heart artery and causes a blockage, usually after the surface of cholesterol plaque in the artery breaks A heart attack, also called a myocardial infarction, usually produces chest pain and shortness of breath It may also cause sudden death If nothing is done to reopen the blocked artery, the heart muscle will die and be replaced by scar tissue More than one million heart attacks occur every year in the United States; it is the leading cause of death from heart disease Most of these deaths occur outside the hospital; It is currently believed that when an arteriosclerotic plaque ruptures, it may cause the blood in a coronary artery to clot on the surface of the plaque If the clot is large enough, it will occlude the artery and block the flow of blood to the heart muscle This will damage or even destroy the heart muscle if there are not enough collateral blood vessels to carry the blood around the occluded vessel; A heart attack occurs when the heart does not get enough blood flow leading; Damage to heart muscle caused by disruption of blood flow usually due to atherosclerosis Also called myocardial infarction; also called myocardial infarction; damage to the heart muscle due to insufficient blood supply; A heart attack occurs when the heart does not get enough blood flow leading to the death of the heart muscle This event is also known as a myocardial infarction; Permanent damage to the heart muscle caused by a lack of blood supply to the heart for an extended time period The severity of damage varies from normal, mild, to severe; occurs when one of more regions of the heart muscle experience a severe or prolonged decrease in oxygen supply caused by a blocked blood flow to the heart muscle; The medical term for heart attack is myocardial infarction A heart attack occurs when the blood supply to part of the heart muscle itself the myocardium is severely reduced or stopped This occurs when one of the coronary arteries that supply blood to the heart muscle is blocked The blockage is usually from the buildup of plaque (deposits of fat-like substances) due to atherosclerosis The plaque can eventually tear or rupture, triggering a blood clot to form that blocks the artery and leads to a heart attack Such an event is sometimes called a coronary thrombosis or coronary occlusion; Heart attacks occur when a coronary artery is completely blocked and a portion of the heart muscle is left without a supply of oxygenated blood If the portion is large enough, the heart attack may be deadly; A lack of blood and oxygen causes death of a portion of the heart muscle The damaged area can be very small or very extensive; A sudden closure or blockage of one or more blood vessels to the heart, cutting off the oxygen supply and causing damage to part of the heart The term specifically refers to death of heart muscle cells, which is usually due to the blockage of a coronary artery; a sudden severe instance of abnormal heart function; Death of or death to part of the heart muscle (myocardium) due to an insufficient blood supply, caused by blockage of one or more of the coronary arteries (infarction); (Also called myocardial infarction ) - occurs when one of more regions of the heart muscle experience a severe or prolonged decrease in oxygen supply caused by a blocked blood flow to the heart muscle; Sudden, severe chest pain that occurs when a portion of the heart no longer receives oxygen-rich blood, usually due to total or near-total blockage of a coronary artery by a blood clot formed in an area already narrowed by plaque The surrounding heart muscle dies and the heart stops working effectively Also called a myocardial infarction (MI) Heart attacks are part of the acute coronary syndrome; The death of heart muscle due to the loss of blood supply The loss of blood supply is usually caused by a complete blockage of a coronary artery, one of the arteries that supplies blood to the heart muscle; Technically known as an acute myocardial infarction (AMI), damage to the heart muscle as a result of insufficient oxygen and nutrients Heart attacks are frequent consequences of coronary heart disease; A sudden decrease in the flow of blood to the heart muscle resulting in impaired heart functioning Can result in death; A heart attack occurs when one of the arteries that supplies blood to the heart muscle becomes suddenly blocked Symptoms are usually severe and sudden in onset They may include fullness, discomfort or squeezing in the chest area radiating to the arms, throat , neck or jaw, followed by nausea and sweating Rapid presentation to the hospital usually by ambulance can be life saving with the implementation of medical and emergent angioplasty procedures to reestablish blood flow to the heart muscle Implantable Defibrillator -- For patients with life threatening heart rhythm abnormalities an implantable defibrillator can be life saving The defibrillator is a surgically implantable electronic device designed to provide an electric shock at the appropriate time to regularize abnormal heart rhythms Incentive Spirometer -- (IS) A device used to measure the volume of air inhaled into the lungs; (sometimes called a "coronary"): this is what happens when the supply of oxygen-rich blood flowing through one or more of the coronary arteries to the heart muscle is cut off If the oxygen supply is severely reduced the heart can malfunction or cut out; A heart attack occurs when part of the blood circulation that feeds the heart is blocked This blockage starves that part of the heart muscle of oxygen, causing it to become damaged This damaged area pumps less efficiently The remainder of the heart muscle pumps normally, but may not fully compensate for the part that doesn’t This results in less efficient pumping, sometimes causing heart failure; (Myocardial Infarction) The death of a portion of heart muscle as a result of inadequate blood supply to the relevant area The diagnosis must be based on: - new electrocardiographic changes indicative of a myocardial infarction, and - elevation of cardiac enzymes If you suffer a heart attack, you will have damage to the heart muscle, which causes changes in the electrocardiogram (ECG) and elevation of cardiac (heart) enzymes The chance finding of ECG changes suggestive of a previous silent heart attack is not covered; heart failure, sudden cessation of heart activity; If someone has a heart attack, their heart begins to beat very irregularly or stops completely. He died of a heart attack brought on by overwork. Sudden interruption or insufficiency of the supply of blood to the heart, typically resulting from occlusion or obstruction of a coronary artery and often characterized by severe chest pain. Also called myocardial infarction. or myocardial infarction Death of a section of heart muscle when its blood supply is cut off, usually by a blood clot in a coronary artery narrowed by atherosclerosis. Hypertension, diabetes mellitus, high cholesterol, cigarette smoking, and coronary heart disease increase the risk. Symptoms include severe chest pain, often radiating to the left arm, and shortness of breath. Up to 20% of victims die before reaching the hospital. Diagnosis is done by electrocardiography and by analysis for enzymes in the blood. Treatment aims to limit the area of tissue death (infarct) and prevent and treat complications. Thrombolytic (clot-dissolving) drugs may be administered. Beta-blockers alleviate pain and slow the heart rate. Angioplasty or coronary bypass restores blood flow to heart muscle. Follow-up may include drugs, exercise programs, and counseling on diet and lifestyle changes; also called myocardial infarction - Damage to the heart muscle due to insufficient blood supply; a sudden loss of blood supply to an area of heart muscle usually due to a blockage in a coronary artery This lack of blood causes that area of heart muscle to die; myocardial infarction
heart attacks: plural form of heart attack
had a heart attack: suffered from a heart attack (sudden coronary failure)
