What is risk stratification before discharge for patients with an ischemia-guided strategy of NSTE-ACS?
Risk stratification before discharge for patients with an ischemia-guided strategy of NSTE-ACS involves noninvasive stress testing in low- and intermediate-risk patients who have been free of ischemia at rest or with low-level activity for a minimum of 24 hours. Clinical evaluation and noninvasive testing aid in the identification of most patients at high risk because they often have one of the following high-risk features: advanced age (>70 years of age), prior MI, revascularization, ST deviation, HF, depressed resting LV function (ie, LVEF 0.40) on noninvasive study, or noninvasive stress test findings, including magnetic resonance imaging. Any of these risk factors or diabetes mellitus may aid in the identification of high-risk patients who could benefit from an invasive strategy.
