  • The simplified Pulmonary Embolism Severity Index (sPESI) score helps identify low-risk patients for home treatment of pulmonary embolism, but its use with direct oral anticoagulants hasn't been thoroughly studied.
  • A study of 2,496 patients with stable pulmonary embolism found that only 25% had an sPESI score of 0, and among those, only 17% were treated at home, though their 30-day mortality was notably low (0% vs. 4.8% in higher risk groups).
  • Factors promoting home treatment included the absence of temporary risk factors, no elevated cardiac biomarkers, and the use of direct oral anticoagulants during the acute phase.

  • Somatic hypermutations (SHMs) in the immunoglobulin heavy chain (IgH) gene are common in diffuse large B-cell lymphoma (DLBCL) and are known to result in immunogenic neoantigens, but their prognostic impact hasn't been extensively studied.
  • The BIOMED-2 PCR protocol, a standard for analyzing lymphoid malignancies, can miss some cases due to these SHMs, prompting the design of three primer sets to enhance detection.
  • A study of 301 DLBCL patients showed that complete detection of IgH V PCR patterns via this improved approach correlated with worse overall survival and progression-free survival compared to patients with different patterns, indicating its potential utility in clinical prognosis.

  • The study investigates the R-CHADS-VASc score's ability to predict cardiovascular events in atrial fibrillation (AF) patients post bioprosthetic valve replacement, using data from the BPV-AF registry with 766 participants.
  • Patients were classified into low, moderate, and high risk based on their R-CHADS-VASc scores, with results indicating that those with higher scores experienced significantly more cardiovascular events during the follow-up period.
  • The findings suggest that the R-CHADS-VASc score is an effective tool for assessing cardiovascular risk in AF patients who have undergone BPV replacement, with higher scores correlating to worse outcomes.

Background: Because the clinical benefit of antiplatelet therapy (APT) for patients with nonsignificant coronary artery disease (CAD) remains poorly understood, we evaluated it in patients after fractional flow reserve (FFR)-guided deferral of revascularization.

Methods And Results: From the J-CONFIRM (Long-Term Outcomes of Japanese Patients with Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), we investigated 265 patients with deferred lesions who did not require APT for secondary prevention of cardiovascular disease. A 2-year landmark analysis assessed the relationship between APT at 2 years and 5-year major cardiac adverse events (MACE: composite of all-cause death, target vessel-related myocardial infarction, clinically driven target vessel revascularization).

  • A study in Japan compared outcomes of patients with venous thromboembolism (VTE) treated with warfarin (2010-2014) versus direct oral anticoagulants (DOACs) (2015-2020) from two multicenter registries.
  • The use of DOACs skyrocketed from 2.6% in the warfarin era to 79% in the DOAC era, leading to a significant reduction in the 5-year recurrence rate of VTE (10.5% to 9.5%).
  • However, the incidence of major bleeding remained similar between the two eras, indicating that while DOACs may reduce VTE recurrence, concerns about bleeding risks continue.
