Renal impairment increases risk of stroke and systemic embolic events and bleeding in patients with atrial fibrillation. Direct oral anticoagulants (DOACs) have varied dependence on renal elimination, magnifying the importance of appropriate patient selection, dosing, and periodic kidney function monitoring. ⋯ Renal function decrease appears less impacted by DOACs, which are associated with a better risk-benefit profile than warfarin in patients with decreasing renal function over time. Limited data address the risk-benefit profile of DOACs in patients with severe impairment or on dialysis.

This study examined the performance of single high-sensitivity cardiac troponin I (hs-cTnI) measurement strategies to rule out acute myocardial infarction. ⋯ Strategies using a single hs-cTnI alone or in combination with a normal ECG allow the immediate identification of patients unlikely to have acute myocardial infarction and who are at very low risk for adverse events at 30 days.

Soluble ST2 (sST2) is a marker of cardiac mechanical strain hypothesized to adversely impact short-term prognosis after myocardial infarction. We examined the association of sST2 with longer-term outcomes after myocardial infarction in a geographically defined community. ⋯ In the community, sST2 elevation is present in half of myocardial infarctions. Higher values of sST2 are associated with a large excess risk of death and heart failure independently of other prognostic indicators. Measurement of sST2 should be considered for risk stratification after myocardial infarction.

Re-hospitalization after discharge for acute decompensated heart failure is a common problem. Low-socioeconomic urban patients suffer high rates of re-hospitalization and often over-utilize the emergency department (ED) for their care. We hypothesized that early consultation with a cardiologist in the ED can reduce re-hospitalization and health care costs for low-socioeconomic urban patients with acute decompensated heart failure. ⋯ Early consultation with a cardiologist in the ED as an adjunct to guideline-based follow-up is associated with reduced re-hospitalization and health care cost for low-socioeconomic urban patients with acute decompensated heart failure.

Comparative Study Observational Study
Early Invasive Versus Initial Conservative Strategies for Women with Non-ST-Elevation Acute Coronary Syndromes: A Nationwide Analysis.
Studies conducted largely in men have shown improved outcomes with an early invasive strategy with non-ST-elevation acute coronary syndrome. In contrast, data have been less conclusive in women, with some trials demonstrating potential harm. This study aims to assess whether an early invasive strategy in women is associated with better outcomes in real-world data. ⋯ In this large contemporary observational analysis of women with non-ST-elevation acute coronary syndrome, an early invasive strategy was associated with lower in-hospital mortality. This benefit was observed in women presenting with non-ST-elevation myocardial infarction but not with unstable angina. These findings provide evidence supporting the guideline recommendations for an early invasive strategy in women with non-ST-elevation acute coronary syndrome and high-risk features (eg, troponin positive).
