BACKGROUND: The APEX trial assessed the safety and efficacy of extended-duration thromboprophylaxis using betrixaban versus standard dosing of enoxaparin among hospitalized, acutely ill medical patients. The 80-mg betrixaban dose was halved to 40 mg among subjects with severe renal insufficiency and those receiving a concomitant strong P-glycoprotein inhibitor. METHODS: This analysis assessed the pharmacokinetics, efficacy, and safety of full- (80 mg) and reduced-dose (40 mg) betrixaban relative to enoxaparin in the APEX trial...

BACKGROUND: Although abnormal left ventricular geometric patterns have prognostic value for morbidity and mortality, their possible association with silent cerebrovascular disease has not been extensively evaluated. METHODS: We examined 665 participants in the CABL study who underwent transthoracic echocardiography and brain magnetic resonance imaging. Participants were divided into 4 geometric patterns: normal geometry (n=397), concentric remodeling (n=89), eccentric hypertrophy (n=126), and concentric hypertrophy (n=53)...

Patients with atrial fibrillation (AF) have many comorbidities and excess risks of hospitalization and death. Whether the impact of comorbidities on outcomes is greater in AF than the general population is unknown. METHODS: One thousand four hundred thirty patients with AF and community controls matched 1:1 on age and sex were obtained from Olmsted County, Minnesota. Andersen-Gill and Cox regression estimated associations of 19 comorbidities with hospitalization and death, respectively...

BACKGROUND: To compare simultaneous recordings from an external patch system specifically designed to ensure better P-wave recordings and standard Holter monitor to determine diagnostic efficacy. Holter monitors are a mainstay of clinical practice, but are cumbersome to access and wear and P-wave signal quality is frequently inadequate. METHODS: This study compared the diagnostic efficacy of the P-wave centric electrocardiogram (ECG) patch (Carnation Ambulatory Monitor) to standard 3-channel (leads V1, II, and V5) Holter monitor (Northeast Monitoring, Maynard, MA)...

Cardioversion is a class I procedure for patients with symptomatic atrial fibrillation (AF) pursuing rhythm control. There are few contemporary reports on quality of life and outcomes after cardioversion. METHODS: Using the nationwide prospective ORBIT-AF registry, cardioversion patients were propensity matched 3:1 to noncardioverted patients and Cox proportional hazards modeling evaluated hospitalization at 1 year in those with and without cardioversion. Cardiovascular outcomes, AF progression, and quality of life were evaluated for the matched cohorts with and without cardioversion...

BACKGROUND: We sought to investigate the relation between frailty indices and 12-month mortality after transcatheter aortic valve implantation (TAVI). METHODS: We included 101 consecutive patients with severe aortic stenosis who have undergone TAVI. Frailty indices according to Valve Academic Research Consortium-2 recommendations (5-m walk test [5MWT] and hand grip strength) as well as other available scales of frailty (Katz index, Elderly Mobility Scale [EMS], Canadian Study of Health and Aging [CSHA] scale, Identification of Seniors at Risk [ISAR] scale) were assessed at baseline...

BACKGROUND: Frequent hospital attendances in patients with implantable cardioverter-defibrillators (ICDs) result in significant morbidity and health care costs. Current drugs to reduce ICD shocks and hospital visits have limited efficacy and considerable toxicity. We evaluated the efficacy and safety of azimilide, a novel oral class III antiarrhythmic, for use in ICD patients. METHODS: A total of 240 patients were enrolled in a prospective, randomized, double-blind, placebo-controlled trial to evaluate the effect of oral azimilide 75 mg daily in ICD patients with previously documented ventricular tachycardia or ventricular fibrillation, and a left ventricular ejection fraction ≤40%...

BACKGROUND: Prior studies have demonstrated cardiorespiratory fitness (CRF) to be a strong marker of cardiovascular health. However, there are limited data investigating the association between CRF and risk of progression to heart failure (HF). The purpose of this study was to determine the relationship between CRF and incident HF. METHODS: We included 66,329 patients (53.8% men, mean age 55 years) free of HF who underwent exercise treadmill stress testing at Henry Ford Health Systems between 1991 and 2009...

The relative outcomes of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI with drug-eluting stent (DES) in complex lesions have not been established. We sought to compare the efficacy and safety of IVUS-guided PCI with angiography-guided PCI in patients with complex coronary lesions treated with DES. METHODS: Electronic databases were searched to identify all randomized trials comparing IVUS-guided vs angiography-guided DES implantation...

Percutaneous coronary intervention (PCI) has been developed by drug-eluting stent (DES), but stent implantation has brought the issue of stent thrombosis and optimal antiplatelet therapy. Guidelines recommend at least 6- to 12 months of dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor such as clopidogrel. Beyond DAPT after PCI with DES, however, there has been still a debate for antiplatelet regimen. Therefore, we report on the upcoming HOST-EXAM trial (NCT02044250), which will evaluate the efficacy and safety of aspirin and clopidogrel monotherapies beyond DAPT after DES implantation...

BACKGROUND: The increasing burden of cardiovascular disease (CVD) in low- and middle-income countries is largely driven by the increasing prevalence of hypertension, diabetes, and tobacco use. We hypothesize that the utilization of community health workers (CHWs) to screen for and manage these 3 determinants of CVD in an integrated manner would be an effective approach to favorably affecting public health. METHODS: We have designed and set up the infrastructure to implement a 2-year community-based cluster randomized controlled trial in an underserved region of West Bengal, India...

Ischemic heart disease is the leading cause of death in India, and there are likely more myocardial infarctions in India than in any other country in the world. We have previously reported heterogeneous care for patients with myocardial infarction in Kerala, a state in southern India, including both gaps in optimal care and inappropriate care. Based on that prior work, limitations from previous nonrandomized quality improvement studies and promising gains in process of care measures demonstrated from previous randomized trials, we and the Cardiological Society of India-Kerala chapter sought to develop, implement, and evaluate a quality improvement intervention to improve process of care measures and clinical outcomes for these patients...

BACKGROUND: Patients with atrial fibrillation (AF) are prone to cardiovascular events and anticoagulation-related bleeding complications. We hypothesized that patients with anemia are at increased risk for these outcomes. METHODS: We performed a post hoc analysis of the ARISTOTLE trial, which included >18,000 patients with AF randomized to warfarin (target international normalized ratio, 2.0-3.0) or apixaban 5 mg twice daily. Multivariable Cox regression analysis was used to determine if anemia (defined as hemoglobin <13...

BACKGROUND: Acute decompensated heart failure (ADHF) is a leading cause of hospitalization in older persons in the United States. Reduced physical function and frailty are major determinants of adverse outcomes in older patients with hospitalized ADHF. However, these are not addressed by current heart failure (HF) management strategies and there has been little study of exercise training in older, frail HF patients with recent ADHF. HYPOTHESIS: Targeting physical frailty with a multi-domain structured physical rehabilitation intervention will improve physical function and reduce adverse outcomes among older patients experiencing a HF hospitalization...

The optimal approach to assess right ventricular (RV) function in patients with acute symptomatic pulmonary embolism (PE) lacks clarity. METHODS: This study aimed to evaluate the optimal approach to assess RV function in normotensive patients with acute symptomatic PE. Outcomes assessed through 30-days after the diagnosis of PE included all-cause mortality and complicated course. RESULTS: Eight hundred forty-eight patients were enrolled. Multidetector computed tomography (MDCT) and transthoracic echocardiography agreed on the presence or absence of RV overload in 449 (53%) patients...

Based on prior research finding the 5HTTLPR L allele associated with increased cardiovascular reactivity to laboratory stressors and increased risk of myocardial infarction, we hypothesized that the 5HTTLPR L allele will be associated with increased blood pressure (BP) and increased hypertension prevalence in 2 large nationally representative samples in the United States and Singapore. METHODS: Logistic regression and linear models tested associations between triallelic (L'S', based on rs25531) 5HTTLPR genotypes and hypertension severity and mean systolic and diastolic blood pressure (SBP and DBP) collected during the Wave IV survey of the National Longitudinal Study of Adolescent to Adult Health (Add Health, N=11,815) in 2008-09 and during 2004-07 in 4196 Singaporeans...

Improving 30-day readmission continues to be problematic for most hospitals. This study reports the creation and validation of sex-specific inpatient (i) heart failure (HF) risk scores using electronic data from the beginning of inpatient care for effective and efficient prediction of 30-day readmission risk. METHODS: HF patients hospitalized at Intermountain Healthcare from 2005 to 2012 (derivation: n=6079; validation: n=2663) and Baylor Scott & White Health (North Region) from 2005 to 2013 (validation: n=5162) were studied...
