Previous studies have shown an inverse relationship between sexual activity and mortality in the general population. We evaluated the association between sexual activity and long-term survival among patients with acute myocardial infarction. ⋯ Using repeated assessments of sexual activity after myocardial infarction, an inverse association was demonstrated with mortality, which was only partly accounted for by measured potential confounders.

A prior hospitalization resulting from heart failure is associated with poor outcomes in ambulatory patients with heart failure. Less is known about this association in hospitalized patients with heart failure and whether it varies by ejection fraction. ⋯ Among hospitalized patients with heart failure, a previous hospitalization for heart failure is associated with higher risks of mortality and readmission in both HFpEF and HFrEF. The relative risks of death and heart failure readmission appear to be higher in HFpEF than in HFrEF.

Acute declines in kidney function occur in approximately 20%-30% of patients with acute decompensated heart failure, but its significance is unclear, and the importance of its context is not known. This study aimed to determine the prognostic value of a decline in kidney function in the context of decongestion among patients admitted with acute decompensated heart failure. ⋯ Decline in kidney function during therapy for acute decompensated heart failure is associated with improved outcomes as long as NT-proBNP levels are decreasing as well, suggesting that incorporation of congestion biomarkers may aid clinical interpretation of eGFR declines.

Electrocardiography (ECG) is used to screen for left ventricular hypertrophy (LVH), but common ECG-LVH criteria have been found less effective in athletes. The purpose of this study was to comprehensively evaluate the value of ECG for identifying athletes with LVH or a concentric cardiac phenotype. ⋯ The diagnostic capacity of all ECG-LVH criteria were inadequate and, therefore, not clinically useful in screening for LVH or a concentric phenotype in athletes. This is probably due to the weak association between LVM and ECG voltage.

The purpose of this study was to evaluate the consistency of 3 commonly used direct-to-consumer genetic testing kits. Genetic testing kits are widely marketed by several companies but the consistency of their results is unclear. Because identical twins share the same DNA, their genetic testing results should provide insight into test consistency. ⋯ The consistency of consumer genetic testing is high for ancestry results within companies but lower and more variable for ancestry results across companies and for specific traits. These results raise questions about the usefulness of such testing.
