Percutaneous coronary intervention (PCI) is not significantly better than a placebo procedure in improving exercise capacity or symptoms, even in patients with severe coronary stenosis, according to the ORBITA study published in The Lancet.
In the absence of epicardial coronary stenosis, an increased oxygen myocardial demand can be achieved by an increase in coronary flow due to arterial vasodilatation, commonly referred to as "coronary reserve," which can increase up to four times the basal blood flow.
The 2014 American Heart Association Consensus Statement on noninvasive diagnostic testing in women with suspected ischemic heart disease highlighted the development of novel diagnostic tools that have an expanded role in the evaluation of symptomatic female patients to detect not only focal epicardial coronary stenosis, but also nonobstructive atherosclerosis as well as the identification of ischemia resulting from microvascular dysfunction.
Following are the indications and appropriate clinical settings for radionuclide cardiac imaging, a) patient has chest pain with 1 or more of the following resting ECG changes: bundle branch blocks, left ventricular hypertrophy, early repolarization abnormalities, b) patient has chest pain and cannot exercise, c) for evaluation after equivocal exercise stress test in patients with intermediate probability of CAD, d) for evaluation of the correlation between coronary stenosis and myocardial ischemia, e) to assess myocardial viability in patients after MI or revascularization and f) to assess existence of preoperative medical risk.
Mortality of CABG patients with significant left main coronary stenosis was 13 out of five hundred fourteen (2.
Patients with clinical evidence of significant ischemia underwent coronary angiography to confirm the severity of coronary stenosis and assess the suitability for revascularization.
In the presence of coronary stenosis, the post-stenotic coronary pressure becomes the input pressure of the myocardial perfusion (Ebadi, Ahmad, et al, 2014; Firoozabadi, Mehdi Dehghani, and Ebadi.
