BACKGROUND Despite the established superiority of mitral repair over replacement, its adoption in the treatment of elderly patients has not been uniform, partly because of a lack of robust long-term survival data. We present the long-term survival of Medicare fee-for-service beneficiaries undergoing mitral valve repair and replacement over a 10-year period.(More)
BACKGROUND Patients with rheumatoid arthritis have an increased risk for accelerated atherosclerosis. It is unknown, however, whether rheumatoid arthritis also increases in-hospital mortality after a myocardial infarction or influences the therapy patients receive. METHODS A cross-sectional analysis of 1,112,676 patients with myocardial infarction in the(More)
Although inpatient mortality rates following total hip arthroplasty are low, understanding factors that influence inpatient mortality rates is important. Discharge data from the 2007-2008 HCUP Nationwide Inpatient Sample database were used in this study. Patients were identified based on whether they were admitted for a primary total hip arthroplasty and(More)
OBJECTIVE People in rural areas live farther away from hospitals than do people in urban areas.
