Randomized Trial of a Vascular Care Team vs Education for Patients With Peripheral Artery Disease.

BACKGROUND: Underutilization of therapies to reduce ischemic risk in peripheral artery disease (PAD) persists. OBJECTIVES: The purpose was to conduct an implementation trial of lipid management in vascular disease. METHODS: The OPTIMIZE PAD-1 (Implementation of Vascular Care Team to Improve Medical Management of PAD Patients) trial randomized patients with peripheral artery disease with low-density lipoprotein cholesterol (LDL-C) ≥70 mg/dL to management via a vascular care team including a clinical pharmacist and an algorithm of intensive lipid management to achieve goal LDL-C in 1 step vs usual care plus provider education. Medications were obtained using commercial insurance. The primary endpoint was percent change in LDL-C at 12 months. RESULTS: Of 166 enrolled patients, 74.2% did not have an LDL-C level at goal. Among 114 randomized patients (mean age 66 years, 36.0% women, and 15.8% Black), 50.9% received high-intensity statin, and 7.9% received ezetimibe at baseline. The mean 12-month LDL-C change was -49.1% (95% CI: -58.7% to -39.5%) with vascular care team management and -5.4% (95% CI: -15.3% to 4.6%) with usual care; the between-group least-squares mean difference was -43.7% (95% CI: -57.6% to -29.9%; P < 0.0001). Mean LDL-C was reduced in vascular care team patients from 100.6 mg/dL at baseline to 54.8 and 50.1 mg/dL by week 4 and month 12, respectively. At 12 months, vascular care team patients were >3 times as likely to achieve LDL-C <70 mg/dL and 8 times as likely to achieve LDL-C <55 mg/dL (P < 0.0001) than usual care. CONCLUSIONS: OPTIMIZE PAD-1 showed that an interprofessional, algorithm-based program can achieve rapid LDL-C lowering in vascular patients using available insurance and therapies, and LDL-C targets can be met in most patients if enabled by optimized systems of care.

Novel valve-in-surgical bioprosthetic transcatheter aortic valve replacement: Undermining iatrogenic coronary obstruction with radiofrequency needle (UNICORN).

An 86-year-old female with history of surgical aortic valve replacement presented with clinical signs of heart failure. Echocardiography revealed a reduction in left ventricular systolic function and severe bioprosthetic aortic valve dysfunction. This is the first reported case of valve-in-valve transcatheter aortic valve replacement with concomitant undermining iatrogenic coronary obstruction with radiofrequency needle procedure in a surgical bioprosthetic valve.

Allergy and the Heart: Eosinophilic Myocarditis With Biventricular Thrombi.

A 40-year-old woman with history of atopy and peripheral eosinophilia presented with clinical signs of heart failure. Echocardiography revealed a restrictive cardiomyopathy with biventricular thrombi. Hypereosinophilic syndrome resulting in eosinophilic myocarditis (Loeffler's syndrome) was diagnosed. This case highlights the workup, diagnosis, and management of hypereosinophilic syndrome with eosinophilic myocarditis. (Level of Difficulty: Advanced.).

Hypertension during Weight Lifting Reduces Flow-Mediated Dilation in Nonathletes.

PURPOSE: The purpose of this study was to determine whether increased intraluminal pressure is the damaging factor that reduces flow-mediated dilation (FMD) in young, healthy subjects after resistance exercise to maximal exertion. HYPOTHESIS: Attenuating the rise in brachial artery pressure during weight lifting by placing a blood pressure cuff on the upper arm prevents postexercise impairment of brachial artery FMD in sedentary individuals. METHODS: Nine sedentary individuals who exercise once a week or less and six exercise-trained individuals who exercise three times a week or more performed leg press exercise to maximal exertion on two separate occasions. During one visit, a blood pressure cuff, proximal to the site of brachial artery measurement, was inflated to 100 mm Hg to protect the distal vasculature from the rise in intraluminal pressure, which occurs during resistance exercise. Brachial artery FMD was determined using ultrasonography before and 30 min after weight lifting. RESULTS: Without the protective cuff, brachial artery FMD in sedentary individuals was reduced after weight lifting (9.0% ± 1.2% prelift vs 6.6% ± 0.8% postlift; P = 0.005), whereas in exercise-trained individuals, FMD was unchanged (7.4% ± 0.7% prelift vs 8.0% ± 0.9% postlift; P = 0.543). With the protective cuff, FMD no longer decreased but rather increased in sedentary individuals (8.7% ± 1.2% prelift vs 10.5% ± 1.0% postlift, P = 0.025). An increase in FMD was also seen in exercise-trained subjects when the cuff was present (6.6% ± 0.7% prelift vs 10.9% ± 1.5% postlift, P < 0.001). CONCLUSION: Protecting the brachial artery from exercise-induced hypertension enhances FMD in sedentary and exercise-trained individuals. These results indicate that increased intraluminal pressure in the artery contributes to the reduced FMD after heavy resistance exercise in sedentary individuals.
