A myocardial infarction may compromise the function of the heart as a pump for the circulation, a state called heart failure. There are different types of heart failure; left- or right-sided (or bilateral) heart failure may occur depending on the affected part of the heart, and it is a low-output type of failure.
Liquefactive necrosis (or colliquative necrosis) is a type of necrosis which results in a transformation of the tissue into a liquid viscous mass. [1] Often it is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn . [ 2 ]
Ischemic coagulative necrosis results and fibrosis of the affected area develops from the reparative response beginning at the preserved margins and working its way inwards. One exception to coagulative necrosis is the brain, which undergoes liquefactive necrosis in response to infarction. [citation needed]
Heart attacks happen when these small arteries become blocked and stop supplying blood to the heart tissue, and if this happens for long enough, heart tissue dies. Almost all heart attacks are ultimately a result of endothelial cell dysfunction, which relates to anything that irritates or inflames the slippery inner lining of the artery—the ...
A healthy diet is a very important factor in preventing coronary ischemia or coronary artery disease. [38] A heart-healthy diet is low in saturated fat and cholesterol and high in fruits, vegetables, and whole grains. [39] Recent studies have shown that there is an inverse correlation between increased fruit and vegetable intake and the risk of ...
In coronary heart disease, the coronary arteries narrow due to the buildup of atheroma or fatty deposits on the vessel walls. The atheroma causes the blood flow of the arteries to be restricted. [6] By restricting the blood flow, the tissue is still receiving some oxygen, but not enough to sustain the tissue over time. [5]
Symptoms include chest pain or angina, shortness of breath, and fatigue. [6]A completely blocked coronary artery will cause a heart attack. [6] Common heart attack symptoms include chest pain or angina, pain or discomfort that spreads to the shoulder, arm, back, neck jaw, teeth or the upper belly, cold sweats, fatigue, heartburn, nausea, shortness of breath, or lightheadedness.
Myocytolysis refers to a state of significant damage to cardiac myocytes, muscle cells of the heart, caused by myocardial strain. It was first described in medical literature by Schlesinger and Reiner in 1955. [1] It is considered a type of cellular necrosis. [1] Two types of myocytolysis have been defined: coagulative and colliquative. [1] [2] [3]
