Howell SJ, et al. - Researchers determined the impact of gender on predischarge cardiac testing (PDT) in low-risk patients evaluated for acute coronary syndrome in a chest pain unit (CPU). They compared the utilization of PDT (exercise treadmill test, myocardial stress perfusion scintigraphy, exercise stress echocardiography, invasive coronary angiography, or no test), as well as incidence of major adverse cardiac events (MACE) at 30 days and 6 months among consecutive low-risk women and men assessed in their CPU over a 2-year period. Overall participants were 619 (54% women). They found that even when PDT was not utilized, a safe and rapid discharge of many low-risk women and men was possible with low risk for MACE at 30 days and at 6 months. Significantly reduced length of stay was reported in relation to exclusion of PDT, which at the same time, also maintained safety in terms of postdischarge MACE.
