Inferior left ventricle wall scar, short axis echocardiography view. Myocardial scarring is the accumulation of fibrous tissue resulting after some form of trauma to the cardiac tissue. [1] [2] Fibrosis is the formation of excess tissue in replacement of necrotic or extensively damaged tissue.
Ventricular aneurysms are usually complications resulting from a heart attack. When the heart muscle (cardiac muscle) partially dies during a heart attack, a layer of muscle may survive, and, being severely weakened, start to become an aneurysm. Blood may flow into the surrounding dead muscle and inflate the weakened flap of muscle into a bubble.
This rare type causes scar tissue to replace normal heart muscle. Stress-induced cardiomyopathy. Also known as “broken heart syndrome,” this type of cardiomyopathy is induced by emotional stress.
Cardiac fibrosis commonly refers to the excess deposition of extracellular matrix in the cardiac muscle, but the term may also refer to an abnormal thickening of the heart valves due to inappropriate proliferation of cardiac fibroblasts. [1] Fibrotic cardiac muscle is stiffer and less compliant and is seen in the progression to heart failure.
Plaques in the walls of the coronary arteries can rupture, resulting in occlusion of the artery and deprivation of blood flow and oxygen to the heart muscle, resulting in cardiac cell death. [9] This is known as myocardial infarction. [9] A heart attack can cause arrhythmias, as well as permanent damage to the heart muscle. [25]
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart.
Loeffler endocarditis is a form of heart disease characterized by a stiffened, poorly-functioning heart caused by infiltration of the heart by white blood cells known as eosinophils. [1] Restrictive cardiomyopathy is a disease of the heart muscle which results in impaired diastolic filling of the heart ventricles , i.e. the large heart chambers ...
Histologically, sarcoidosis of the heart is an active granulomatous inflammation surrounded by reactive oedema. The distribution of affected areas is patchy with localised enlargement of heart muscles. This causes scarring and remodelling of the heart, which leads to dilatation of heart cavities and thinning of heart muscles.
