Cumulative incidence of death and rehospitalization among the elderly in the first year after NSTEMI.
The researchers evaluated mortality and cause-specific rehospitalization rates in elderly non-ST-segment elevation myocardial infarction survivors with ischemic heart disease. They found that rehospitalization rates do not rise substantially with advancing age, and rehospitalization is often for noncardiac diagnoses.

Free levels of selected organic solutes and cardiovascular morbidity and mortality in hemodialysis patients: results from the Retained Organic Solutes and Clinical Outcomes (ROSCO) investigators.
This study examined the association of baseline free levels of four organic solutes that are secreted in the native kidney —p-cresol sulfate, indoxyl sulfate, hippurate and phenylacetylglutamine—with outcomes in hemodialysis patients. It found that free levels of uremic solutes that are secreted by the native kidney are associated with a higher risk of cardiovascular morbidity and mortality in incident hemodialysis patients.

Early mortality after aortic valve replacement with mechanical prosthetic vs bioprosthetic valves among Medicare beneficiaries: a population-based cohort study.
The researchers compared early mortality after aortic valve replacement (AVR) between the recipients of mechanical and bioprosthetic aortic valves. Among 66,453 Medicare beneficiaries who received AVRs, use of mechanical valves was associated with a higher risk for death on the date of surgery and within 30 days compared with the bioprosthetic aortic valves. However, this applied only to those who underwent concurrent AVR and coronary artery bypass graft but not isolated AVR.

Association of Nurse-to-Patient Ratio with mortality and preventable complications following aortic valve replacement.
The purpose of this study was to examine hospital resources associated with patient outcomes for aortic valve replacement (AVR), including inpatient adverse events and mortality. The investigators found that the hospital volume-outcomes relationship was associated with mortality outcomes but not postoperative complications. They identified structural differences in hospital size, nurses-to-patient ratio, and nursing skill level indicative of high quality outcomes.
