Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease, and heart attacks. [4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [5]
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 ...
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.
A myocardial infarction, according to established consensus, is defined by elevated cardiac biomarkers with a rising or falling trend and at least one of the following: [82] Symptoms relating to ischemia; Changes on an electrocardiogram (ECG), such as ST segment changes, new left bundle branch block, or pathologic Q waves
Cardiac ischemia may be asymptomatic or may cause chest pain, known as angina pectoris. It occurs when the heart muscle, or myocardium , receives insufficient blood flow. [ 10 ] This most frequently results from atherosclerosis , which is the long-term accumulation of cholesterol-rich plaques in the coronary arteries .
The word corona is a Latin word meaning "crown", from the Ancient Greek κορώνη (korōnè, "garland, wreath"). It was applied to the coronary arteries because of a notional resemblance (compare the photos). The word arterie in Anglo-French (artaire in Old French, and artērium in Latin) means "windpipe" and "an artery". It was applied to ...
The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...
