    OBJECTIVE: The risk of acute type B aortic dissection is thought to increase with descending thoracic aortic diameter. Currently, elective repair of the descending thoracic aorta is indicated for an aortic diameter of 5.5 cm or greater. We sought to investigate the relationship between aortic diameter and acute type B aortic dissection, and the utility of aortic diameter as a predictor of acute type B aortic dissection.

    METHODS: We examined the descending aortic diameter at presentation ...

    Importance: In a recent meta-analysis of randomized clinical trials, femoropopliteal artery revascularization with paclitaxel drug-coated devices was associated with increased long-term all-cause mortality compared with non-drug-coated devices. However, to our knowledge, these findings have not been replicated in other data sources and may be subject to confounding from missing data associated with patient withdrawal and loss to follow-up.

    Objective: To evaluate differences in all-cause ...

    OBJECTIVE: To evaluate whether early initiation of prophylactic anticoagulation compared with no anticoagulation was associated with decreased risk of death among patients admitted to hospital with coronavirus disease 2019 (covid-19) in the United States.

    DESIGN: Observational cohort study.

    SETTING: Nationwide cohort of patients receiving care in the Department of Veterans Affairs, a large integrated national healthcare system.

    PARTICIPANTS: All 4297 patients admitted to hospital from 1 ...

    Intensive antithrombotic therapy reduces major adverse cardiovascular events (MACE) and major adverse limb events (MALE) in patients with peripheral artery disease (PAD). Recent studies have suggested heterogeneity in risk and benefit in those with and without concomitant coronary artery disease (CAD) and peripheral revascularization. We evaluated the risk of MACE and MALE in patients with PAD stratified by history of concomitant CAD and prior peripheral revascularization and whether the ...

    CONTEXT: Whether androgen deprivation therapy (ADT) causes excess cardiovascular deaths in men with prostate cancer is highly controversial and was the subject of a joint statement by multiple medical societies and a US Food and Drug Administration safety warning.

    OBJECTIVE: To perform a systematic review and meta-analysis of randomized trials to determine whether ADT is associated with cardiovascular mortality, prostate cancer-specific mortality (PCSM), and all-cause mortality in men ...

    CONTEXT: Complications of atherosclerosis cause most morbidity and mortality in patients with diabetes mellitus. Despite the frequency and severity of disease, proven medical therapy remains incompletely understood and underused.

    OBJECTIVE: To review the epidemiology, pathophysiology, and medical and invasive treatment of atherosclerosis in patients with diabetes mellitus.

    DATA SOURCES: Using the index terms diabetes mellitus, myocardial infarction, peripheral vascular diseases, ...

    BACKGROUND: Patency or thrombosis of the false lumen in type B acute aortic dissection has been found to predict outcomes. The prognostic implications of partial thrombosis of the false lumen have not yet been elucidated.

    METHODS: We examined 201 patients with type B acute aortic dissection who were enrolled in the International Registry of Acute Aortic Dissection between 1996 and 2003 and who survived to hospital discharge. Kaplan-Meier mortality curves were stratified according to the ...

    BACKGROUND: The mechanism of adverse limb events associated with peripheral artery disease remains incompletely understood. We investigated whether microvascular disease is associated with amputation in a large cohort of veterans to determine whether microvascular disease diagnosed in any location increases the risk of amputation alone and in concert with peripheral artery disease.

    METHODS: Participants in the Veterans Aging Cohort Study were recruited from April 1, 2003 through December ...

    OBJECTIVE: Evidence suggesting a beneficial effect of cardioprotective medications in patients with lower extremity atherosclerosis derives largely from secondary prevention studies of heterogeneous populations. Patients with critical limb ischemia (CLI) have a large atherosclerotic burden with related high mortality. The effect of such therapies in this population is largely inferred and unproven.

    We tested the hypothesis that a combination of measurements of different aspects of atherosclerosis, including burden of atherosclerosis and levels of inflammation, would contain more predictive information than either alone in an outpatient population. We enrolled 110 patients (62 +/- 15 years of age) who were referred to the noninvasive vascular laboratory for sequential Doppler pressure measurements of the lower extremities. We measured ankle-brachial index (ABI) and serum markers of ...

    Cigarette smoking impairs endothelial function. Hydroxymethylglutaryl (HMG) CoA reductase inhibitors (statins) may favorably affect endothelial function via nonlipid mechanisms. We tested the hypothesis that statins would improve endothelial function independent of changes in lipids in cigarette smokers. Twenty normocholesterolemic cigarette smokers and 20 matched healthy control subjects were randomized to atorvastatin 40 mg daily or placebo for 4 weeks, washed out for 4 weeks, and then ...

    The bioavailability of nitric oxide is decreased in animal models and humans with diabetes mellitus. Hyperglycemia, in particular, attenuates endothelium-dependent vasodilation in healthy subjects. In vitro and in vivo animal studies implicate activation of protein kinase Cbeta as an important mechanism whereby hyperglycemia decreases endothelium-derived nitric oxide. Accordingly, this study tested the hypothesis that inhibition of protein kinase Cbeta would prevent impairment of ...

    BACKGROUND: Endothelium-dependent vasodilation is impaired in patients with insulin-dependent and non-insulin-dependent diabetes mellitus and restored by vitamin C administration, implicating a causative role for oxidant stress. Hyperglycemia per se attenuates endothelium-dependent vasodilation in healthy subjects. Accordingly, this study investigated whether impaired endothelium-dependent vasodilation caused by hyperglycemia in nondiabetic humans is restored by administration of the ...

    BACKGROUND: Mechanisms underlying the association between age-related arterial stiffening and poor brain health remain elusive. Cerebral blood flow (CBF) homeostasis may be implicated. This study evaluates how aortic stiffening relates to resting CBF and cerebrovascular reactivity (CVR) in older adults.

    METHODS: Vanderbilt Memory & Aging Project participants free of clinical dementia, stroke, and heart failure were studied, including older adults with normal cognition (n=155; age, 72±7 ...

    BACKGROUND: Bilirubin, with recently recognized antioxidant and antiinflammatory activity, has emerged as a candidate for atheroprotection. We hypothesized that higher levels of bilirubin would reduce susceptibility to peripheral arterial disease (PAD).

    METHODS AND RESULTS: We analyzed 7075 adults with data available on the ankle brachial index, serum total bilirubin level, and PAD risk factors in the National Health and Nutrition Examination Survey (1999 to 2004), a nationally ...
