Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.
Heart block. Heart block (HB) [1] is a disorder in the heart 's rhythm due to a fault in the natural pacemaker. [2] This is caused by an obstruction – a block – in the electrical conduction system of the heart. Sometimes a disorder can be inherited. Despite the severe-sounding name, heart block may cause no symptoms at all in some cases, or ...
A heart attack (also known as a myocardial infarction) occurs when the flow of blood to an area of the heart is blocked, often because of a buildup of substances like fat or cholesterol.
A heart attack occurs when blood flow to the heart becomes blocked. The most common cause is atherosclerosis, but other conditions like a blood clot, spasm, or tear in your coronary arteries can ...
Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis, a buildup of cholesterol and fats in the artery walls. The smaller vessel diameter allows less blood to flow and facilitates progression to a myocardial infarction. Leading risk factors for coronary thrombosis are high low-density lipoprotein cholesterol ...
Heart: Myocardial infarction (MI), commonly known as a heart attack, is an infarction of the heart, causing some 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 ...
