Cardiac MRI can be used to diagnose microvascular angina. Studies are ongoing to validate this approach. There is growing evidence that microvascular angina is caused by a functional disorder of the microvessels, coronary microvascular dysfunction (CMD). Blood vessels either fail to dilate or constrict in response to various stressors such as ...
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 ...
Cardiovascular MRI is complementary to other imaging techniques, such as echocardiography, cardiac CT, and nuclear medicine. The technique has a key role in evidence-based diagnosis and treatment of cardiovascular disease. [4]
A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in the coronary arteries that can narrow arteries and increase the risk of heart attack. [17]
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.
Microvascular occlusions can be caused by heparin-induced thrombocytopenia, cryoglobulinemia, angioinvasive organisms, embolization, disseminated intravascular coagulation, livedoid vasculopathy, cell occlusion syndromes, and iatrogenic causes. [3]
