Coronary artery disease (CAD) is the most common cause of coronary ischemia. [7] Coronary ischemia and coronary artery disease are contributors to the development of heart failure over time. [ 10 ] Diagnosis of coronary ischemia is achieved by an attaining a medical history and physical examination in addition to other tests such as ...
Coronary artery ectasia is characterized by the enlargement of a coronary artery to 1.5 times or more than its normal diameter. [1] The disease is commonly asymptomatic and is normally discovered when performing tests for other conditions such as coronary artery disease, stable angina and other acute coronary syndromes.
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 atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [1]
People who have a normal ECG and who are able to exercise, for example, do not merit routine imaging. [13] Imaging tests such as stress radionuclide myocardial perfusion imaging or stress echocardiography can confirm a diagnosis when a person's history, physical exam, ECG and cardiac biomarkers suggest the likelihood of a problem.
The first investigation when CAD is suspected is an electrocardiogram (ECG/EKG), both for stable angina and acute coronary syndrome. An X-ray of the chest, blood tests and resting echocardiography may be performed. [73] [74] For stable symptomatic patients, several non-invasive tests can diagnose CAD depending on pre-assessment of the risk profile.
Cardiac markers are used for the diagnosis and risk stratification of patients with chest pain and suspected acute coronary syndrome and for management and prognosis in patients with diseases like acute heart failure. Most of the early markers identified were enzymes, and as a result, the term "cardiac enzymes" is sometimes used. However, not ...
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 CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
