Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.
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. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
Data involving cardiac ischemia resulting from post acute COVID syndrome (or Long COVID) is evolving. Various studies have been combined to show a significant percentage of patients presenting with myocardial ischemia post COVID infection (infection requiring hospitalization) with no documented prior history of coronary disease.
To exemplify, Dilated Cardiomyopathy in adults is associated with Ischemic Cardiomyopathy, Hypertension, Valvular diseases, and Genetics. While in Children, Neuromuscular diseases such as Becker muscular dystrophy, including X-linked genetic disorder, are directly linked with their Cardiomyopathies.
The signs and symptoms of ischemia vary, as they can occur anywhere in the body and depend on the degree to which blood flow is interrupted. [4] For example, clinical manifestations of acute limb ischemia (which can be summarized as the "six P's") include pain, pallor, pulseless, paresthesia, paralysis, and poikilothermia.
It is the most common form of non-ischemic cardiomyopathy and the dilatation of the heart results in larger chamber volumes & thinner myocardial walls, both of which decrease the ability to pump. Specific kinds of dilated cardiomyopathy are listed below, and other causes include Chagas disease , chemotherapeutic agents (e.g., doxorubicin ...
Subepicardial fibrosis, which is associated with non-infarction diagnoses such as myocarditis [28] and non-ischemic cardiomyopathy. [ 29 ] Healthy myocardium versus interstitial fibrosis in dilated cardiomyopathy.
Hypoxic ischemic brain injury is a concerning outcome for people suffering a cardiac arrest. [148] Most improvements in cognition occur during the first three months following cardiac arrest, with some individuals reporting improvement up to one year post-cardiac arrest.
