Howell SJ, et al. - Researchers assessed if predischarge cardiac testing (PDT) has utility in low-risk patients assessed for acute coronary syndrome in a chest pain unit (CPU). They also analyzed the impact of gender on PDT. They evaluated occurrence of major adverse cardiac events (MACE) at 30 days and 6 months in 619 consecutive low-risk women and men assessed in their CPU over a 2-year period after PDT utilization (exercise treadmill test, myocardial stress perfusion scintigraphy, exercise stress echocardiography, invasive coronary angiography) or no test. Even in the absence of PDT, it was possible to discharge many low-risk women and men safely and rapidly after being evaluated in a CPU for acute coronary syndrome, and these subjects still had a low risk for MACE at 30 days and at 6 months. A significantly shorter length of stay and sustained safety in terms of postdischarge MACE were seen in relation to excluding PDT.
