Microvascular angina (MVA), previously known as cardiac syndrome X, [1] also known as coronary microvascular dysfunction (CMD) or microvascular coronary disease is a type of angina (chest pain) with signs associated with decreased blood flow to heart tissue but with normal coronary arteries. [2] [3]
Microangiopathy (also known as microvascular disease, small vessel disease (SVD) or microvascular dysfunction) is a disease of the microvessels, small blood vessels in the microcirculation. [1] It can be contrasted to macroangiopathies such as atherosclerosis , where large and medium-sized arteries (e.g., aorta , carotid and coronary arteries ...
Ranolazine for coronary microvascular disease. Statins or other medications to treat high cholesterol levels. Medications to treat blood clots.
Evidence is accumulating that nearly half of females with myocardial ischemia have coronary microvascular disease, a condition often called microvascular angina (MVA). Small intramyocardial arterioles constrict in MVA causing ischemic pain that is less predictable than with typical epicardial coronary artery disease (CAD).
Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart muscle. Without enough blood supply , the heart is unable to work properly, especially under increased stress.
Coronary no-reflow phenomenon is specifically related to reduced antegrade coronary blood flow despite proximal coronary artery patency. It is an independent predictor of worse clinical outcomes including heart failure, fatal arrhythmias, myocardial infarction, and increased mortality rates.
Seven major factors (i.e. history of out of hospital cardiac arrest [score = 4]; smoking, angina at rest, physically obstructive coronary artery disease, and spasm in multiple coronary arteries [score = 2]; and presence of ST segment elevations on ECG and history of using beta blockers [score = 1]) where assigned the indicated scores ...
An antianginal is a drug used in the treatment of angina pectoris, a symptom of ischaemic heart disease. Myocardial ischemia arises from the dysfunction of coronary macrovascular or microvascular components, leading to a compromised supply of oxygen and nutrients to the myocardium. The underlying pathophysiological mechanisms encompass a range ...
