The detection of high-grade coronary artery stenosis by a cardiac stress test was the key to recognizing people who have heart attacks since 1980.

Angina (coronary artery stenosis)

Fractional flow reserve, a technique used in coronary catheterization to measure pressure differences across a coronary artery stenosis.

High degrees of coronary artery stenosis, which are detected by stress testing methods are often, though not always, responsible for recurrent symptoms of angina.

Transesophageal Echocardiographic Assessment of Proximal Coronary Artery Stenosis in Elderly Patients with Ischemic Stroke.

Wellens' syndrome (or sign, or occasionally warning) is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in patients with unstable angina.

And, of course, smoking was not thought to be hazardous to anybody until a few years ago and now, of course, we know that it causes lung cancer, pulmonary disease and coronary artery stenosis.

Transesophageal Echocardiography Performed in Stroke Patients to Exclude Cardiac Sources of Embolism Accurately Detects Significant Proximal Coronary Artery Stenosis and Often Changes Management.

The American Heart Association recommends ECG treadmill testing as the first choice for patients with medium risk of coronary heart disease according to risk factors of smoking, family history of coronary artery stenosis, hypertension, diabetes and high cholesterol.

Thakur AC, Voros S, Nanda NC, Gomez CR, Terry JB, Tulyapronchote R, Ocako: Transesophageal Echocardiographic Diagnosis of Proximal Coronary Artery Stenosis in Patients with Ischemic Stroke.

In these studies, MCG was performed on patients who were scheduled for elective coronary angiography by cardiologists who, on the basis of clinical impression and standard non-invasive testing, believed that the patients had an intermediate to high risk of having relevant coronary artery stenosis (CAS).
