What patient characteristics generally prefer an invasive strategy?
Recurrent angina or ischemia at rest or with low-level activities despite intensive medical therapy, elevated cardiac biomarkers (TnT or TnI), new or presumably new ST-segment depression, signs or symptoms of HF or new or worsening mitral regurgitation, high-risk findings from noninvasive testing, hemodynamic instability, sustained ventricular tachycardia, PCI within 6 months, prior CABG, and high-risk score (e.g. TIMI, GRACE)
