Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1] An irregular heart beat and fainting may occur. [1]
Echocardiography is a safe and non-invasive method that can be used to assess the structural and functional disease of the heart. [4] Amyloidosis presents with ventricle and valvular thickening, biatrial enlargement, [ 4 ] restrictive filling pattern, with normal to mildly reduced systolic function [ 8 ] and decreased diastolic filling . [ 4 ]
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 ...
The heart muscle may become inflamed in a condition called myocarditis, [46] most commonly caused by a viral infection [47] but sometimes caused by the body's own immune system. [48] Heart muscle can also be damaged by drugs such as alcohol, long standing high blood pressure or hypertension, or persistent abnormal heart racing. [49]
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.
During COVID-19, the other indirect mechanisms thought to contribute to myocarditis include: oxygen supply-demand mismatch to the heart muscle leading to myocardial (heart muscle) injury; microvascular thrombi, or blood clots in the small blood vessels of the heart causing injury; the systemic hyperinflammatory state in Covid-19 leading to ...
[6]: 3612 Heart failure is the potential end stage of all heart diseases. [40] Common causes of heart failure include coronary artery disease, including a previous myocardial infarction (heart attack), high blood pressure, atrial fibrillation, valvular heart disease, excess alcohol use, infection, and cardiomyopathy of an unknown cause.
The cardiac muscle pattern is elegant and complex, as the muscle cells swirl and spiral around the chambers of the heart, with the outer muscles forming a figure 8 pattern around the atria and around the bases of the great vessels and the inner muscles, forming a figure 8 around the two ventricles and proceeding toward the apex.
