The heat of the sauna relaxes muscles and promotes relaxation, reducing stress levels, and cortisol. Cardiac perfusion scans are usually safe. For potential or actual medical emergencies, immediately call 911 or your local emergency service. Stress-induced perfusion abnormalities in regions that exhibit normal perfusion at rest are termed reversible perfusion defects, and such regions represent viable, ischemic tissue with blunted coronary blood flow reserve. Unlike exercise stress, the perfusion defect induced with pharmacologic vasodilator stress may represent merely the heterogeneity in coronary flow reserve without inducing myocardial ischemia (with the exception of coronary steal).
