Comparative effectiveness of angiotensin II receptor blockers and angiotensin-converting enzyme inhibitors in older nursing home residents after myocardial infarction: a retrospective cohort study.
Evidence regarding differences in outcomes between angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) among older nursing home (NH) residents after acute myocardial infarction (AMI) is limited. The purpose of this study was to estimate the post-AMI effects of ARBs versus ACEIs on mortality, rehospitalization, and functional decline outcomes in this important population.

Association of neutrophil-to-lymphocyte ratio with outcomes after elective abdominal aortic aneurysm repair.
This study investigated postoperative outcomes from elective abdominal aortic aneurysm surgery (AAA) repair using neutrophil-to-lymphocyte ratio as the predictor. Inpatients from the Cerner Health Facts database undergoing elective AAA repair from 2008 to 2015 were selected using ICD-9 procedure codes. Patients with a high postoperative NLR experienced longer hospital stays; higher rates of in-hospital death; high rates of renal failure, cardiac problems, respiratory problems, and infection compared to patients with a low postoperative NLR. The authors recommend future study of NLR to help provide clinically important risk profiles.

Assessing quality improvement capacity in primary care practices.
The Healthy Hearts Northwest (H2N) Study is part of an AHRQ initiative to build quality improvement (QI) capacity in primary care with a focus on cardiovascular risk factors. The three main risk factors are appropriate aspirin use, blood pressure control, and tobacco screening/cessation. A practice facilitator (PF) met with clinicians and staff in the participating practices to discuss the results for each item on the Quality Improvement Capacity Assessment (QICA) scale. The score was associated with prior experience managing change and moderately associated with two of the three risk factors: aspirin use and blood pressure control. The QICA was found to be a useful assessment tool to measure QI capacity within a practice.

Virtual educational outreach intervention in primary care based on the principles of academic detailing.
This paper describes the efforts of the Healthy Hearts Northwest (H2N) EvidenceNOW cooperative in providing virtual outreach intervention in primary care based on the principles of academic detailing (AD). EvidenceNOW is AHRQ’s initiative to fund seven regional cooperatives to identify and implement effective strategies to improve the quality of cardiovascular care in communities across the United States. The H2N network covers three states: Oregon, Washington, and Idaho. For this initiative they recruited 259 primary care practices that had 10 full-time or fewer providers and met stage 1 electronic health record meaningful use criteria. The aim was to increase adoption of the four ABCS of heart disease prevention: Aspirin use by high-risk individuals, Blood pressure control, Cholesterol management, and Smoking cessation. Due to the long distances and staffing limitations H2N decided to develop an educational outreach program using virtual visits instead of the traditional AD program structure. The findings and outcomes of this program is described in detail in this paper.

Assessment of outcomes of treatment with oral anticoagulants in patients with atrial fibrillation and multiple chronic conditions: a comparative effectiveness analysis.
The purpose of this retrospective comparative effectiveness analysis was to determine whether there are differences in efficacy and safety of dabigatran, rivaroxaban, and warfarin regarding stroke prevention and bleeding rates, respectively, in elderly patients with atrial fibrillation (AF) with multiple chronic conditions (MCC). The investigators concluded that oral anticoagulants were similarly effective in stroke prevention among patients with AF with MCC. However, the indicate that dabigatran and rivaroxaban use may be associated with lower rates of mortality in patients with MCC.

Sex and race differences in the utilization and outcomes of coronary artery bypass grafting among Medicare beneficiaries, 1999-2014.
The authors sought to evaluate how the use of coronary artery bypass grafting (CABG) and its outcomes have evolved in different sex and racial subgroups. Using Medicare data, they found that women and black patients had persistently higher CABG mortality than men and white patients, respectively, despite greater declines over the time period. The authors conclude that these findings indicate progress, but further progress is needed.

Mineralocorticoid receptor antagonism in patients with atrial fibrillation: findings from the ORBIT-AF (Outcomes Registry for Better Informed Treatment of Atrial Fibrillation) registry.
Mineralocorticoid receptor antagonist (MRA) therapy may be beneficial to patients with atrial fibrillation (AF), but little is known about their use in patients with AF and subsequent outcomes. In order to better understand MRA use and subsequent outcomes, the investigators performed a retrospective cohort study of the contemporary ORBIT-AF (Outcomes Registry for Better Informed Treatment of Atrial Fibrillation) registry.

Cardiac rehabilitation and readmissions after heart transplantation.
Cardiac transplant recipients always are referred to cardiac rehabilitation (CR) after transplantation, and is associated with a lower 1-year readmission risk. This study’s objective was to determine rates of CR for heart transplant recipients in the US and also 1-year readmission rates using 2013-2014 Medicare data. Out of the 2,531 heart transplant patients in the US in 2013, about 24% received Medicare coverage and were included in the study. Rates of CR utilization was only, with only 55% participating in the program. Younger transplant patients ages 35 to 49 years were less likely to initiate CR than patients 65 and older. In all groups patients did not attend all 36 prescribed sessions, with a mean of 26.7 sessions attended. The 1-year readmission risk was 29% lower for CR participation patients.

Generalized boosted modeling to identify subgroups where effect of dabigatran versus warfarin may differ: an observational cohort study of patients with atrial fibrillation.
The purpose of this study was to explore generalized boosted modeling (GBM) as a method for identifying subgroups with greater benefit or harm with dabigatran versus warfarin for treatment of atrial fibrillation. The investigators concluded that dabigatran's superiority to warfarin at prevention of thromboembolism may be greater in secondary than primary prevention. They indicated that in practice, secondary prevention patients are more often treated with warfarin.

Association of cardiac rehabilitation with decreased hospitalizations and mortality after ventricular assist device implantation.
This study examined whether outcomes of cardiac patients who had received ventricular assist device (VAD) implementation had decreased hospitalization and mortality with cardiac rehabilitation (CR). Medicare beneficiaries enrolled for disability or aged 65 years and older in 2014 were included. The investigators identified VAD recipients by diagnosis codes. It was found that each 5-year increase in age was associated with attending an additional 1.6 CR sessions and there was a 23% lower 1-year hospitalization risk and a 47% lower 1-year mortality risk.

Use of mineralocorticoid receptor antagonists in patients with heart failure and comorbid diabetes mellitus or chronic kidney disease.
Perceived risks of hyperkalemia and acute renal insufficiency may limit use of mineralocorticoid receptor antagonist (MRA) therapy in patients with heart failure, especially those with diabetes mellitus or chronic kidney disease. In their study, the investigators found that among patients with heart failure and diabetes mellitus or chronic kidney disease, MRA use was associated with lower risk of all-cause readmission despite greater risk of hyperkalemia and acute renal insufficiency.

Comparative effectiveness of cardiac resynchronization therapy among patients with heart failure and atrial fibrillation: Findings from the National Cardiovascular Data Registry's Implantable Cardioverter-Defibrillator Registry.
The researchers investigated the outcomes of patients with both atrial fibrillation and heart failure who receive cardiac resynchronization therapy with defibrillator (CRT-D) compared with an implantable cardioverter-defibrillator (ICD) alone. They found that CRT-D was associated with lower risks of mortality, all-cause readmission, and heart failure readmission, as well as with a similar risk of complications compared with ICD alone.
