BACKGROUND Because of the increased use of pacemakers and implantable cardioverter defibrillators, infection has become a complication with significant morbidity and mortality. Data on risk factors for mortality in patients with cardiac-device related infection are limited. We evaluated the prognostic significance of key clinical and echocardiographic variables in a large retrospective populati...

BACKGROUND Although several macrolide antibiotics are proarrhythmic and associated with an increased risk of sudden cardiac death, azithromycin is thought to have minimal cardiotoxicity. However, published reports of arrhythmias suggest that azithromycin may increase the risk of cardiovascular death. METHODS We studied a Tennessee Medicaid cohort designed to detect an increased risk of death ...

BACKGROUND Numerous studies have compared the outcomes of two competing interventions for multivessel coronary artery disease: coronary-artery bypass grafting (CABG) and coronary stenting. However, little information has become available since the introduction of drug-eluting stents. METHODS We identified patients with multivessel disease who received drug-eluting stents or underwent CABG in ...

PURPOSE Recently, much media attention has been given to the premature deaths in professional wrestlers. Since no formal studies exist that have statistically examined the probability of premature mortality in professional wrestlers, we determined survival estimates for active wresters over the past quarter century to establish the factors contributing to the premature mortality of these indivi...

BACKGROUND AND PURPOSE Cerebral small vessel disease may be related to vascular and nonvascular pathology. We assessed whether lacunar infarcts and white matter lesions on MRI increased the risk of vascular and nonvascular death and future vascular events in patients with atherosclerotic disease. METHODS Brain MRI was performed in 1309 patients with atherosclerotic disease from the Second Man...

CONTEXT Although increased blood pressure is associated with adverse outcomes in the general population, elevated blood pressure is associated with decreased mortality in patients with end-stage renal disease undergoing maintenance hemodialysis. Recent investigations in the general population have demonstrated the predictive utility of pulse pressure (systolic minus diastolic blood pressure), a...

Treatment of heart failure with preserved ejection fraction (HFpEF) spironolactone is associated lower risk hospitalization (HFH) but increased worsening renal function (WRF). The prognostic implications spironolactone-associated WRF in HFpEF patients are not well understood. purpose this study was to investigate the association between WRF, treatment, and clinical outcomes HFpEF. In 1,767 rand...

Background: The changes in the risk of disease failure over time in nasopharyngeal carcinoma (NPC) remains unknown. Methods: We analyzed 749 patients treated with intensity-modulated radiotherapy in a single center. The annual hazard rates of disease failure (recurrence or death from any cause) were estimated using the life-table method. Results: In total, 41 (5.5%), 22 (2.9%) and 129 (17.2%) p...

BACKGROUND Digoxin is widely used in patients with atrial fibrillation despite the lack of randomized controlled trials. Observational studies report conflicting results regarding its association with mortality, perhaps because of residual confounding by the presence of heart failure (HF). METHODS AND RESULTS In the ENGAGE AF-TIMI 48 (Effective Anticoagulation With Factor Xa Next Generation i...
