BACKGROUND Benefits of drug-eluting stents (DES) in percutaneous coronary intervention (PCI) are greatest in those at the highest risk of target-vessel revascularization (TVR). Drug-eluting stents cost more than bare-metal stents (BMS) and necessitate prolonged dual antiplatelet therapy (DAPT), which increases costs, bleeding risk, and risk of complications(More)
CONTEXT Despite the widespread use of percutaneous coronary intervention (PCI), the appropriateness of these procedures in contemporary practice is unknown. OBJECTIVE To assess the appropriateness of PCI in the United States. DESIGN, SETTING, AND PATIENTS Multicenter, prospective study of patients within the National Cardiovascular Data Registry(More)
have jointly accepted responsibility for establishing " Environmental Assessment and Remediation: A Practice Parameter. " This is a complete and comprehensive document at the current time. The medical environment is a changing environment, and not all recommendations will be appropriate for all patients. Because this document incorporated the efforts of(More)
BACKGROUND We developed risk models for predicting acute kidney injury (AKI) and AKI requiring dialysis (AKI‐D) after percutaneous coronary intervention (PCI) to support quality assessment and the use of preventative strategies. METHODS AND RESULTS AKI was defined as an absolute increase of ≥0.3 mg/dL or a relative increase of 50% in serum creatinine(More)
BACKGROUND Rehospitalizations for acute coronary syndromes (ACS) and coronary revascularization after an acute myocardial infarction (AMI) are not only common and costly but can also impact patients' quality of life. In contrast to mortality and all-cause readmissions, little insight is available into risk factors associated with ACS and revascularization(More)
Secondhand tobacco smoke (SHS) is a common indoor environmental exposure that is particularly prevalent in low-income families. It has been found to be associated with asthma in some studies; however, across all relevant studies, results have been conflicting. This study aimed to determine the prevalence of SHS exposure in the home environment in a(More)
BACKGROUND The volume-outcome relationship associated with intensive care unit (ICU) experience with managing acute myocardial infarction (AMI) remains inadequately understood. METHODS AND RESULTS Within a multicenter clinical ICU database, we identified patients with a primary ICU admission diagnosis of AMI between 2008 and 2010 to evaluate whether(More)
BACKGROUND Rehospitalizations following acute myocardial infarction for unplanned coronary revascularization and unstable angina (UA) are often included as parts of composite end points in clinical trials. Although clearly costly, the clinical relevance of these individual components has not been described. METHODS AND RESULTS Patients enrolled in a(More)
BACKGROUND The Centers for Medicaid and Medicare Services (CMS) and the National Cardiovascular Data Registry (NCDR) track primary percutaneous coronary intervention (PCI) performance in the form of door-to-balloon time. For quality assessment, exceptions are made for patients with "unavoidable delays" in both registries, yet it remains unclear how(More)
