BackgroundIn non-valvular atrial fibrillation (NVAF) patients, congestive heart failure (CHF) confers an increased risk of stroke or systemic thromboembolism. This risk is present in both heart failure (HF) with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). It is unclear if clinicians account for both types of CHF in their NVAF anticoagulation practices. Accordingly, we characterized current outpatient anticoagulation trends in NVAF patients with HFpEF compared to patients with HFrEF.MethodsThe outpatient NCDR PINNACLE-AF registry was analyzed to identify patients with NVAF and CHF. The study population was subdivided into HFpEF (ie, LVEF ≥ 40%) and HFrEF (LVEF

BackgroundSex-based differences in acute coronary syndrome (ACS) mortality may attenuate with age due to better symptom recognition and prompt care.HypothesisAge is a modifier of temporal trends in sex-based differences in ACS care.MethodsAmong 104 817 eligible patients with ACS enrolled in the AHA Get With the Guidelines-Coronary Artery Disease registry between 2003 and 2008, care and in-hospital mortality were evaluated stratified by sex and age. Temporal trends within sex and age groups were assessed for 2 care processes: percentage of STEMI patients presenting to PCI-capable hospitals with a DTB time ≤ 90 minutes (DTB90) and proportion of eligible ACS patients receiving aspirin within 24 hours.ResultsAfter adjustment for clinical risk factors and sociodemographic and hospital characteristics, 2276 (51.7%) women and 6276 (56.9%) men with STEMI were treated with DTB90 (adjusted OR: 0.85, 95% CI: 0.80-0.91, P

Although guidelines and performance measures exist for patients with diabetes mellitus, achievement of these metrics is not well known. The Diabetes Collaborative Registry® (DCR) was formed to understand the quality of diabetes mellitus care across the primary and specialty care continuum in the United States. We assessed the frequency of achievement of 7 diabetes mellitus-related quality metrics and variability across the Diabetes Collaborative Registry® sites. Among 574 972 patients with diabetes mellitus from 259 US practices, median (interquartile range) achievement of the quality metrics across the practices was the following: (1) glycemic control: 19% (5-47); (2) blood pressure control: 80% (67-88); (3) angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers in patients with coronary artery disease: 62% (51-69); (4) nephropathy screening: 62% (53-71); (5) eye examination: 0.7% (0.0-79); (6) foot examination: 0.0% (0.0-2.3); and (7) tobacco screening/cessation counseling: 86% (80-94). In hierarchical, modified Poisson regression models, there was substantial variability in meeting these metrics across sites, particularly with documentation of glycemic control and eye and foot examinations. There was also notable variation across specialties, with endocrinology practices performing better on glycemic control and diabetes mellitus foot examinations and cardiology practices succeeding more in blood pressure control and use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers. The Diabetes Collaborative Registry® was established to document and improve the quality of outpatient diabetes mellitus care. While target achievement of some metrics of cardiovascular risk modification was high, achievement of others was suboptimal and highly variable. This may be attributable to fragmentation of care, lack of ownership among various specialists concerning certain domains of care, incomplete documentation, true gaps in care, or a combination of these factors.

BackgroundPatients with paroxysmal and persistent atrial fibrillation experience a similar risk of thromboembolism. Therefore, consensus guidelines recommend anticoagulant therapy in those at risk for thromboembolism irrespective of atrial fibrillation classification. We sought to examine whether there are differences in rates of appropriate oral anticoagulant treatment among patients with paroxysmal vs persistent atrial fibrillation in real-world cardiology practices.MethodsWe studied 71,316 outpatients with atrial fibrillation and intermediate to high thromboembolic risk (CHADS2 score ≥2) enrolled in the American College of Cardiology PINNACLE Registry between 2008 and 2012. Using hierarchical modified Poisson regression models adjusted for patient characteristics, we examined whether anticoagulant treatment rates differed between patients with paroxysmal vs persistent atrial fibrillation.ResultsThe majority of outpatients (78.4%, n = 55,905) had paroxysmal atrial fibrillation. In both unadjusted and multivariable adjusted analyses, patients with paroxysmal atrial fibrillation were less frequently prescribed oral anticoagulant therapy than those with persistent atrial fibrillation (50.3% vs 64.2%; adjusted risk ratio [RR] 0.74; 95% confidence interval [CI], 0.72-0.76). Instead, patients with paroxysmal atrial fibrillation were prescribed more frequently only antiplatelet therapy (35.1% vs 25.0%; adjusted RR 1.77; 95% CI, 1.69-1.86) or neither antiplatelet nor anticoagulant therapy (14.6% vs 10.8%; adjusted RR 1.35; 95% CI, 1.26-1.44; P < .0001 for differences across all 3 comparisons).ConclusionsIn a large, real-world cardiac outpatient population, patients with paroxysmal atrial fibrillation with a moderate to high risk of stroke were less likely to be prescribed appropriate oral anticoagulant therapy and more likely to be prescribed less effective or no therapy for thromboembolism prevention.

OBJECTIVES: We sought to investigate the prevalence and predictors of oral anticoagulation prescription among patients with atrial fibrillation (AF) at the lowest risk for thromboembolism, despite contemporary consensus guidelines that do not recommend anticoagulation therapy in this population. BACKGROUND: In young and healthy AF patients without significant thromboembolic risk factors, anticoagulant treatment carries bleeding risks that outweigh stroke prevention benefit. METHODS: Within a large contemporary registry of cardiology outpatients, we identified low-risk patients with AF meeting criteria for a contemporary consensus guideline class III indication against use of anticoagulation (age < 60 years, CHADS2 Score=0, and no structural heart disease) between 2008–2012, and a second cohort with the same criteria and a CHA2DS2-VASc Score of 0. Using hierarchical modified Poisson regression models adjusted for patient characteristics, we examined predictors of oral anticoagulation treatment in these low thromboembolic risk AF patients. RESULTS: Oral anticoagulation was prescribed in a total of 2,561 of 10,995 (23.2%) AF patients with a CHADS2 score of 0 and 1,787 of 6,730 (26.6%) AF patients with a CHA2DS2-VASc score of 0. In multivariable analysis, older age (RR 1.48 per 10 years; 95% CI, 1.41–1.56; p

ObjectivesCHARISMA was a landmark randomized clinical trial that failed to demonstrate a benefit of dual antiplatelet therapy (DAPT) over aspirin alone for preventing cardiovascular events. However, subgroup analyses of the trial found fewer major adverse cardiovascular events (MACEs) for patients with established cardiovascular disease but more MACEs for patients with multiple risk factors without established cardiovascular disease. Our objective was to examine DAPT use in contemporary clinical practice after publication of CHARISMA results.Study designRetrospective analysis of a large clinical registry of outpatient cardiovascular visits to over 1000 physicians that collected data on patient clinical history, symptoms, vital signs, and medications.MethodsClinical characteristics and prescription rates of aspirin and clopidogrel were compared for patients with established cardiovascular disease and for patients with only multiple cardiovascular risk factors. Prescription of DAPT by calendar quarter was evaluated from 2008 to 2011 using multivariable Poisson regression models.ResultsOf 167,839 patients with established cardiovascular disease, 20.5% were prescribed both aspirin and clopidogrel. Of 20,478 patients with multiple risk factors but no known cardiovascular disease, 3.5% were prescribed both aspirin and clopidogrel. Across 14 calendar quarters, prescription rates of DAPT did not change significantly for patients with established CVD but decreased for patients with multiple risk factors with an incidence rate ratio of 0.77.ConclusionsUse of DAPT is modest in patients with established cardiovascular disease, for whom the CHARISMA trial suggested decreased MACEs, and prescription rates have remained stable over time. Use of DAPT in patients with multiple risk factors only, for whom CHARISMA suggested that DAPT may lead to increased MACE, was low and decreased over time.

Background: Post-hospitalization remote patient monitoring (RPM) has potential to improve health outcomes for high-risk patients with chronic medical conditions. The purpose of this study is to determine the extent to which RPM for patients with congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD) is associated with reductions in post-hospitalization mortality, hospital readmission, and ED visits within an Accountable Care Organization (ACO). Methods: Nonrandomized prospective study of patients in an ACO offered enrollment in RPM upon hospital discharge between February 2021 and December 2021. RPM comprised of vital sign monitoring equipment (blood pressure monitor, scale, pulse oximeter), tablet device with symptom tracking software and educational material, and nurse-provided oversight and triage. Expected enrollment was for at least 30-days of monitoring, and outcomes were followed for 6 months following enrollment. The co-primary outcomes were (a) the composite of death, hospital admission, or emergency care visit within 180 days of eligibility, and (b) time to occurrence of this composite. Secondary outcomes were each component individually, the composite of death or hospital admission, and outpatient office visits. Adjusted analyses involved doubly robust estimation to address confounding by indication. Results: Of 361 patients offered remote monitoring (251 with CHF and 110 with COPD), 140 elected to enroll (106 with CHF and 34 with COPD). The median duration of RPM-enrollment was 54 days (IQR 34–85). Neither the 6-month frequency of the co-primary composite outcome (59% vs 66%, FDR p-value = 0.47) nor the time to this composite (median 29 vs 38 days, FDR p-value = 0.60) differed between the groups, but 6-month mortality was lower in the RPM group (6.4% vs 17%, FDR p-value = 0.02). After adjustment for confounders, RPM enrollment was associated with nonsignificantly decreased odds for the composite outcome (adjusted OR [aOR] 0.68, 99% CI 0.25–1.34, FDR p-value 0.30) and lower 6-month mortality (aOR 0.41, 99% CI 0.00–0.86, FDR p-value 0.20). Conclusions: RPM enrollment may be associated with improved health outcomes, including 6-month mortality, for selected patient populations. [ABSTRACT FROM AUTHOR]
