Promoting Cardiac Rehabilitation in Acute Coronary Syndrome Patients: Quality Initiative Based on Education, Automated Referral, and Multidisciplinary Rounds.

Cardiac rehabilitation is a class 1 recommendation for acute coronary syndrome (ACS) patients according to the American College of Cardiology/American Heart Association. However, only 1 in 5 ACS patients are referred for cardiac rehabilitation nationally, and even fewer at our institution. We sought to improve the number of referrals to cardiac rehabilitation for post-ACS patients admitted to our inpatient cardiology service, and ultimately their participation in the program. We designed a quality improvement initiative that included education of patients and house staff, automated referral order, and participation of cardiac rehabilitation staff members on multidisciplinary rounds. We compared the number of patients who received a referral to cardiac rehabilitation, had the first appointment scheduled before hospital discharge, and attended the program before and after our intervention. Six months after initiation of the project, the proportion of ACS patients referred to cardiac rehabilitation before hospital discharge increased from 10% to 43% (P < 0.001). The mean number of patients with a cardiac rehabilitation appointment scheduled before discharge was 2 before and 5 after the intervention (P < 0.001), and the mean number of patients who attended their scheduled appointment was 1 before and 3 after the intervention (P = 0.001). Run charts demonstrated that the number of referrals and the number of scheduled appointments remained above the median following the intervention. In conclusion, an initiative that included education, automated referrals, and direct one-on-one contact with cardiac rehabilitation staff before discharge increased the number of cardiac rehabilitation referrals, and appointments scheduled and attended in post-ACS patients.

Sex-Based Differences in Coronary and Structural Percutaneous Interventions.

In the current state of interventional cardiology, the ability to offer advanced therapies to patients who historically were not surgical candidates has grown exponentially in the last few decades. As therapies have expanded in complex coronary and structural interventions, the nuances of treating certain populations have emerged. In particular, the role of sex-based anatomic and outcome differences has been increasingly recognized. As guidelines for cardiovascular prevention and treatment for certain conditions may vary by sex, therapeutic interventions in the structural and percutaneous coronary areas may also vary. In this review, we aim to discuss these differences, the current literature available on these topics, and areas of focus for the future.

Association of Vegetation Size With Embolic Risk in Patients With Infective Endocarditis: A Systematic Review and Meta-analysis.

Importance: Infective endocarditis is a life-threating condition with annual mortality of as much as 40% and is associated with embolic events in as many as 80% of cases. These embolic events have notable prognostic implications and have been linked to increased length of stay in intensive care units and mortality. A vegetation size greater than 10 mm has often been suggested as an optimal cutoff to estimate the risk of embolism, but the evidence is based largely on small observational studies. Objective: To study the association of vegetation size greater than 10 mm with embolic events using meta-analytic techniques. Data Sources: A computerized literature search of all publications in the PubMed and EMBASE databases from inception to May 1, 2017, was performed with search terms including varying combinations of infective endocarditis, emboli, vegetation size, pulmonary infarct, stroke, splenic emboli, renal emboli, retinal emboli, and mesenteric emboli. This search was last assessed as being up to date on May 1, 2017. Study Selection: Observational studies or randomized clinical trials that evaluated the association of vegetation size greater than 10 mm with embolic events in adult patients with infective endocarditis were included. Conference abstracts and non-English language literature were excluded. The search was conducted by 2 independent reviewers blinded to the other's work. Data Extraction and Synthesis: Following PRISMA guidelines, the 2 reviewers independently extracted data; disputes were resolved with consensus or by a third investigator. Categorical dichotomous data were summarized across treatment arms using Mantel-Haenszel odds ratios (ORs) with 95% CIs. Heterogeneity of effects was evaluated using the Higgins I2 statistic. Results: The search yielded 21 unique studies published from 1983 to 2016 with a total of 6646 unique patients with infective endocarditis and 5116 vegetations with available dimensions. Patients with a vegetation size greater than 10 mm had increased odds of embolic events (OR, 2.28; 95% CI, 1.71-3.05; P < .001) and mortality (OR, 1.63; 95% CI, 1.13-2.35; P = .009) compared with those with a vegetation size less than 10 mm. Conclusions and Relevance: In this meta-analysis of 21 studies, patients with vegetation size greater than 10 mm had significantly increased odds of embolism and mortality. Understanding the risk of embolization will allow clinicians to adequately risk stratify patients and will also help facilitate discussions regarding surgery in patients with a vegetation size greater than 10 mm.

Thoracic aortic aneurysms: state of the art and current controversies.

INTRODUCTION: Complications of thoracic aortic aneurysms (TAA), including aortic rupture and dissection, are often catastrophic and prophylactic intervention can be lifesaving. Controversies exist regarding the standardization of aortic imaging techniques, the best metric for assessing aortic risk and the optimal threshold for intervention. Areas covered: This review summarizes recent temporal trends in TAA disease, provides an overview of the role of multi-modality imaging in diagnosis of the disease, and reviews controversies around surgical thresholds for intervention and medical therapies in the management of TAA disease. Expert commentary: While death from TAA appears to be declining, it remains an important cause of morbidity and mortality. Multi-modality imaging has revolutionized the diagnosis and follow up of TAAs but knowledge of the nuances of how images are acquired and measurements made are important. Emerging evidence suggests that the cross sectional area to height ratio may be a better measure of aortic risk, especially in those who do not meet current surgical thresholds. The use of medications to delay disease progression is controversial, but given the overall good safety profile of medications such as beta-blockers and angiotensin receptor blockers, they should be considered in all patients with TAA disease.
