Comparative Study
ST-elevation myocardial infarction mortality in a major academic center "on-" versus "off-" hours.
A higher mortality rate for weekend myocardial infarction (MI) admissions has been reported and attributed to the lower availability of primary percutaneous coronary intervention (PCI) during off-hours. However, the data are conflicting and, furthermore, inapplicable to hospitals where primary PCI is invariably performed. ⋯ Higher rates of in-hospital mortality and cardiogenic shock may be expected in STEMI patients admitted during off-hours, even when primary PCI is performed. Longer DTB times during off-hours may partially explain our findings. Strategies to optimize reperfusion time during off-hours, including perhaps a 24/7 in-house "STEMI team" may be necessary.

Outcomes after percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (AMI) complicated by renal insufficiency have been well described. However, data regarding admission serum creatinine and coronary and myocardial flow are scant. The aims of this study are to evaluate the effects of admission serum creatinine on coronary blood flow and prognosis in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary PCI. ⋯ The elevated admission serum creatinine levels are associated with impaired myocardial flow and poor prognosis in STEMI patients undergoing primary PCI.
