Designing a patient-specific search of transplant program performance and outcomes: feedback from heart transplant candidates and recipients.
The Scientific Registry of Transplant Recipients provides transplant program-specific information, but it is unclear what patients and stakeholders need to know. Acceptance criteria for the candidate waitlist and donor organs vary by program and region, but there is no means to search for programs by the clinical profiles of recipients and donors. The authors examined variability in program-specific characteristics that could influence access to transplantation.

Long-term trends in preoperative cardiac evaluation and myocardial infarction after elective vascular procedures.
This retrospective cohort study was performed using data on elective vascular surgery procedures and evaluated long-term trends in post-operative myocardial infarction (POMI) using Vascular Surgery Vascular Quality Initiative (VQI) registry data for patients undergoing carotid endarterectomy (CEA), thoracic endovascular aortic repair (TEVAR), endovascular aortic repair (EVAR), open abdominal aortic aneurysm repair (oAAA), suprainguinal bypass (SIB), and infrainguinal bypass (IIB). A total of 227,837 elective procedures were identified. The overall rate of POMI was 1.3% across all procedures. POMI rates from 2003-05 to 2015-17 for CEA decreased from 0.9% to 0.7%, EVAR from 2% to 7%, IIB from 3.8% to 2.4%, and oAAA from 6.8% to 5.1%. From 2009 to 2017 SIB decreased from 3.06% to 2.95%. However, TEVAR increased from 2.4% to 3.56% for the period 2006 to 2017. CEA, EVAR, IIB, oAAA all showed a significant increase in postoperative statin use.

Discontinuation rates of warfarin versus direct acting oral anticoagulants in US clinical practice: results from Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II (ORBIT-AF II).
The objective of this study was to evaluate discontinuation rates among patients on warfarin and direct oral anticoagulants (DOACs) in clinical practice. Over 10,000 AF patients were enrolled from the ORBIT-AF II Registry as subjects. Findings showed that, in a community based atrial fibrillation cohort, adjusted rates of discontinuation at 12 months were higher in DOAC-treated versus vitamin K antagonist-treated patients. Discontinuation of oral anticoagulation was associated with increased absolute risk of all-cause mortality and cardiovascular death.

Angiotensin-converting enzyme inhibitor prescription for patients with single ventricle physiology enrolled in the NPC-QIC registry.
This study examined trends in the routine use of angiotension-converting enzyme inhibitors (ACEI) during palliation of hypoplastic left heart syndrome, which is considered controversial. The authors used patients enrolled in the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) registry from 2008 to 2016 who had been prescribed ACEI between stage 1 palliation (stage I Norwood procedure) discharge and stage 2 palliation (stage II superior cavopulmonary anastomosis procedure) admission. ACEI prescriptions declined from 45% in the pre-2010 period to 36.8% from 2011 to 2016. No difference was found in interstage mortality, change in atrioventricular valve regurgitation, or change in ventricular dysfunction between groups. Atrioventricular septal defect, and preoperative mechanical ventilation were associated with increased ACEI prescription.

Association of use of an intravascular microaxial left ventricular assist device vs intra-aortic balloon pump with in-hospital mortality and major bleeding among patients with acute myocardial infarction complicated by cardiogenic shock.
This study examines outcomes among patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) complicated by cardiogenic shock. Two interventions are compared: intravascular microaxial left ventricular assist devices (LVADs) versus intra-aortic balloon pumps (IABPs). The American College of Cardiology’s National Cardiovascular Data Registry was used to identify patients with AMI complicated by cardiogenic shock from hospitals participating in the CathPCI and Chest Pain-MI registries and identified 28,304 patients. Over the study period (2015 to 2017), LVAD was used in 6.2% of patients and IABP in 29.9%. LVAD was shown to have higher rates of in-hospital death and major bleeding complications compared to IABP.

Attribution of adverse events following coronary stent placement identified using administrative claims data.
This study outlines the process used to identify adverse events following coronary stent placement identified with administrative claims data. Deterministic matching was used to link the National Cardiovascular Data Registry (NCDR) CathPCI Registry to Medicare fee-for-service claims for patients aged 65 and older who underwent percutaneous coronary interventions (PCIs) with drug-eluting stents (DESs) between July 2009 and December 2013. Out of 415,306 DES placements in 368,194 patients, 278 (1.1%) were attributed to the same coronary artery in which the DES was implanted during the index PCI. The authors concluded that more in-depth examination will be needed to accurately assess stent safety using claims data alone.

Improving care pathways for acute coronary syndrome: patients undergoing percutaneous coronary intervention.
This study examined ways to improve care pathways for acute coronary syndrome (ACS) patients who are low-risk with no complications. They looked at 434,172 low-risk uncomplicated ACS patients eligible for early discharge from the Premier database and identified ACS care pathways. They compared percutaneous coronary intervention (PCI) types (trans-radial intervention [TRI] vs. transfemoral intervention (TFI) and by length of stay (LOS). Associations with costs and outcomes were tested using hierarchical, mixed-effects regression and projections of cost savings were obtained using modeling. More cost-savings were associated with TRI versus TFI. There was not an increased risk of adverse outcomes with a shorter LOS.

Incremental cost of acute kidney injury after percutaneous coronary intervention in the United States.
This study examined incremental costs of acute kidney injury (AKI) complications from percutaneous coronary intervention (PCI), which is a common and severe complication. Out of a sample of over 1.4 million PCI patients at 518 US hospitals from 2006 to 2015, AKI occurred in 5.73% of PCI patients. Those with AKI had at least double the hospitalization costs and the incremental cost was $9,448. It was also independently associated with an incremental length of stay of 3.6 days. AKI cost burden was extrapolated at 411.3 million US dollars annually.

Rhythm control versus rate control in patients with atrial fibrillation and heart failure with preserved ejection fraction: insights from get with the guidelines-heart failure.
Researchers analyzed the Get With The Guidelines - Heart Failure (GWTG-HF) registry linked to Medicare claims data to describe current treatments for rate versus rhythm control and subsequent outcomes in patients with heart failure with preserved ejection fraction and atrial fibrillation. They found that rhythm control in patients aged 65 and older with heart failure with preserved ejection fraction and AF was associated with a lower risk of one-year all-cause mortality. They recommended future prospective randomized studies to explore this potential benefit.

Hospital participation in clinical trials for patients with acute myocardial infarction: results from the National Cardiovascular Data Registry.
Using the nationwide Chest Pain-MI registry, the authors described the proportion of hospitals that enrolled patients with acute myocardial infarction (MI) in clinical trials from 2009 to 2014. They concluded that hospitals are becoming less likely to engage in clinical trials for patients with MI, and that patients admitted to hospitals that participated in clinical trials more often received guideline-adherent care and had better long-term outcomes.

Impact of heart failure type on thromboembolic and bleeding risk in patients with atrial fibrillation on oral anticoagulation.
Differential impact of heart failure (HF) category on thromboembolic and bleeding risk in atrial fibrillation (AF) patients on oral anticoagulation (OAC) is unknown. In this study, the investigators used Medicare data for beneficiaries with new AF diagnosed between 2011 and 2013 to identify patients with HF with reduced ejection fraction (HFrEF), HF with preserved ejection fraction (HFpEF), and no HF. The investigators concluded that in AF patients, HFrEF and HFpEF are both associated with higher risk of ischemic stroke, HF and AMI admissions, even after adjusting for OAC use, compared with patients without HF.

Advanced practice provider versus physician-only outpatient follow-up after acute myocardial infarction.
This study examines the prevalence of using advanced practice providers (APPs) for care following myocardial infarction as opposed to physicians due to physician shortages and reimbursement changes. Outpatient cardiology or primary care visits within 90 days of MI among 29,477 Medicare-insured patients aged 65 or older from 364 hospitals were examined from data in the Acute Coronary Treatment Intervention Outcomes Network Registry. Medicare adherence, all-cause readmission risk, mortality, and major adverse cardiovascular events were compared for patients seen by APPs versus physicians only. Patients seen by APPs were more likely to have diabetes mellitus, heart failure, be discharged to a nursing facility, and had more outpatient visits. There was no differences in the factors listed between patients seen by APPs or physicians. Patients seen by APPs were in more need of frequent monitoring and were more likely to have other chronic conditions leading to higher risk of post-MI complications.

Quantifying the utilization of medical devices necessary to detect postmarket safety differences: a case study of implantable cardioverter defibrillators.
The purpose of this study was to estimate medical device utilization needed to detect safety differences among implantable cardioverter defibrillators (ICDs) generator models and compare these estimates to utilization in practice. The investigators concluded that small safety differences among ICD generator models are unlikely to be detected through routine surveillance given current ICD utilization in practice, but large safety differences can be detected for most patients at anticipated average adverse event rates.

Linkage of Medicare records to the interagency registry of mechanically assisted circulatory support.
This study merged Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) records with CMS Medicare claims regarding adults receiving durable FDA-approved mechanical circulatory support devices (MCSDs) in order to investigate the uncertainty of penetrance of Medicare beneficiaries within INTERMACS. The results indicated that there was an annual increase in CMS and INTERMACS centers performing durable MCSD implants among adults from 2008 to 2013, but the CMS centers outnumbered the INTERMAC centers throughout this period. Representation within INTERMACS of MCSDs implanted in Medicare beneficiaries more than doubled in 2013. The authors conclude that ‘the vast majority’ of Medicare beneficiaries receiving MCSDs are increasingly captured in INTERMACS, and that contemporary studies in INTERMACS are therefore relevant and generalizable to the Medicare population.

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.

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.

Scope of sacubitril/valsartan eligibility after heart failure hospitalization: findings from the GWTG-HF Registry (Get With The Guidelines-Heart Failure).
Researchers used the Get With The Guidelines-Heart Failure (GWTG-HF) registry to characterize patients’ eligibility and potential barriers for sacubitril/valsartan initiation. The GWTG-HF registry was established by the American Heart Association to improve adherence to quality of care guidelines for patients hospitalized with heart failure. The FDA has approved sacubitril/valsartan for patients with heart failure with reduced ejection fraction (HFrEF); however, FDA labeling is broader than the trial entry criteria, and the scope of potential sacubitril/valsartan use in HFrEF is not well understood. Findings suggest that discharge from hospitalization from acute heart failure may be an opportunity for re-evaluating medications, including potentially switching the patient from ACEI/ARB, or starting sacubitril/valsartan.

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.

Trends in 30-day readmission rates for patients hospitalized with heart failure: findings from the Get With The Guidelines-Heart Failure Registry.
The researchers analyzed data from the Heart Failure registry linked to Medicare claims between 2009 and 2012 to describe trends and relative reduction of rates of 30-day all-cause readmission among patients with heart failure. They concluded that although there has been slight improvement in 30-day all-cause readmission rates during the past 4 years in patients with heart failure, few hospitals have seen large success.

Patterns of institutional review of percutaneous coronary intervention appropriateness and the effect on quality of care and clinical outcomes.
The researchers sought to determine whether internal review of percutaneous coronary intervention (PCI) appropriateness using appropriate use criteria is associated with differences in procedural appropriateness, quality of care, and patient outcomes. They concluded that there was a modest association between procedural appropriateness and clinical outcomes and a similarly modest correlation between nonacute PCI volume and procedural appropriateness.
