Despite diagnostic and therapeutic advances, infective endocarditis (IE) is still associated with high mortality rates. Currently, there are no good prognostic tools for the risk assessment of patients with IE. The CHADS-VASc score, used to estimate the risk of ischemic stroke in patients with non-valvular atrial fibrillation (AF), has been shown to be a powerful predictor of stroke and death in patients without known AF associated with other cardiovascular conditions. We aimed to evaluate the usefulness of the CHADS-VASc score as a prognostic tool in a population of patients with IE. The Rabin Medical Center Endocarditis Team (RMCET) registry is a retrospective cohort of all patients evaluated at our center due to acute or sub-acute bacterial endocarditis. The CHADS-VASc score was extracted for all patients. All-cause mortality was depicted for all patients. The cohort included 330 patients with a mean age of 65.2 ± 14.7 years (70% men). During a median follow-up of 24 months [IQR 4.7-48.6], 121 (36.7%) patients died. The median CHADS-VASc score was 3, and any score above 2 was associated with increased overall mortality (50.8% vs. 19.9%, < 0.001). A multivariate model incorporating important confounders not included in the CHADS-VASc model showed consistent results with a risk increase of 121% for the higher CHADS-VASc score groups (HR 2.21 [CI 1.12-4.39], = 0.023). IE currently has no good risk stratification models for clinical practice. The CHADS-VASc score might serve as a simple and available tool to stratify risk among patients with IE.

Impact of Time in Therapeutic Range on Adverse Events in Atrial Fibrillation Patients in an Ambulatory Care Setting.
Hosp Pharm
December 2024
Maxor National Pharmacy Services Corp, Amarillo, TX, USA.
This study examines the correlation between time-in-therapeutic range (TTR) and anticoagulation-related adverse events (AEs) in patients with atrial fibrillation (Afib) in a pharmacist-managed ambulatory care clinic. A single-center, retrospective cohort study was conducted at a community hospital-based outpatient anticoagulation clinic to investigate the predictive value of suboptimal TTR percentages for hemorrhagic or thromboembolic events in Afib patients. Eligible participants were aged 18 years or older, diagnosed with Afib, and receiving warfarin therapy as current or past enrollees in the anticoagulation management program.

Article Synopsis
- The study aimed to determine the effectiveness and safety of low-dose direct oral anticoagulation (DOAC) compared to dual antiplatelet therapy (DAPT) in patients who underwent left atrial appendage occlusion (LAAO) for three months post-procedure.
- Conducted across three European sites, the ADALA trial faced challenges with participant recruitment due to the COVID-19 pandemic and was halted prematurely, involving only 90 patients.
- The main outcomes assessed included the rates of major bleeding and thromboembolic events, with the study analyzing patients who had a history of bleeding and various health profiles.
Evaluating Short-Term Outcomes of Tunneled and Non-Tunneled Central Venous Catheters in Hemodialysis.

: The necessity of using central venous catheters (CVCs) in hemodialysis, coupled with their associated complications, remains a critical concern in nephrology. This study aims to compare the short-term prognosis of tunneled (T-CVC) and non-tunneled (NT-CVC) CVCs in acute hemodialysis patients, specifically focusing on infection rates, malpositioning, and lumen thrombosis within the first three weeks post-insertion. : A retrospective analysis was conducted on 176 CVCs placed between January and December 2023 at the Policlinico di Modena and the Ospedale Civile di Baggiovara.

Background: Advances in imaging have led to procedural optimization of left atrial appendage closure (LAAC). Contrast-free approaches, guided merely by echocardiography, have been established, however data on this topic remains scarce. In this analysis, we assessed contrast-free procedural results with the LAMBRE LAAC device.

Article Synopsis
- About 25% of patients with embolic stroke have an unknown cause, but atrial fibrillation (AF) is a common mechanism, especially in older individuals.
- A systematic review of studies was conducted to identify ECG patterns that can predict AF in patients already in sinus rhythm.
- The findings revealed multiple ECG abnormalities linked to increased AF risk, and clinical factors like age and chronic diseases can enhance predictive accuracy, potentially aiding in better patient management and treatment.
