Abstract
Myocardial ischemia is triggered by amismatch between the oxygen supply and demand of the myocardial tissue. The most common cause is coronary artery disease; however, not every coronary stenosis is hemodynamically relevant and leads to myocardial ischemia. The guidelines recommend noninvasive ischemia diagnostics prior to invasive treatment in patients with chronic coronary syndrome. Cardiac computed tomography, stress echocardiography, nuclear cardiological procedures (positron emission tomography and single photon emission computed tomography) and cardiac magnetic resonance imaging are the main diagnostic tools for this purpose and are incorporated into the clinical routine. This article provides a review of the indications, the relative advantages and disadvantages of the respective methods and their utilization in routine clinical practice.
