COVID-19 is associated with an increased risk of venous thromboembolism (VTE) in hospitalized patients. Although prior studies have attempted to identify predictors of VTE, restricted sample size and use of administrative claims data have limited such analyses. We utilized data from hospitalized patients in the CORONA-VTE Network, a United States multicenter registry of adult patients with PCR-confirmed COVID-19 (N = 3,844).

- Pregnancy can increase the risk of thrombotic and cardiovascular events, but the study investigates this risk specifically for outpatient pregnant women with COVID-19.
- In a sample of 6,585 outpatients, only 169 were pregnant, and by 90 days post-diagnosis, two women had venous thrombosis, resulting in a low thrombotic event rate of 1.20%.
- The study concludes that while the risk of thrombotic and cardiovascular events exists, the absolute rates are low enough that widespread preventative measures may not be necessary for outpatient pregnant women with COVID-19.
Background: Despite widely available risk stratification tools, safe and effective anticoagulants, and guideline recommendations, anticoagulation for stroke prevention in atrial fibrillation (AF) is under-prescribed in ambulatory patients. To assess the impact of alert-based computerized decision support (CDS) on anticoagulation prescription in ambulatory patients with AF and high-risk for stroke, we conducted this randomized controlled trial.
Methods: Patients with AF and CHADSVASc score ≥ 2 who were not prescribed anticoagulation and had a clinic visit at Brigham and Women's Hospital were enrolled.
Cardiovascular abnormalities, such as left ventricular hypertrophy and valvular disorders, particularly mitral valve prolapse, have been described as highly prevalent among adult patients with autosomal dominant polycystic kidney disease (ADPKD). The present study aimed to assess echocardiographic parameters in a large sample of both normotensive and hypertensive ADPKD patients, regardless of kidney function level, and evaluate their association with clinical and laboratorial parameters. A retrospective study consisted of the analysis of clinical, laboratorial, and transthoracic echocardiograms data retrieved from the medical records of young adult ADPKD outpatients.

However, the risk of recurrence may be increased in the presence of enduring risk factors. In such patients, the optimal duration of treatment remains uncertain.

Objectives: To assess the frequency of arterial and venous thromboembolic disease, risk factors, prevention and management patterns, and outcomes in patients with COVID-19, the authors designed a multicenter, observational cohort study.
Methods: We analyzed a retrospective cohort of 1,114 patients with COVID-19 diagnosed through our Mass General Brigham integrated health network.
