AI Article Synopsis

  • The CRUSADE score is used to assess in-hospital bleeding risks for patients with NSTEMI going through PCI, particularly in Asian populations like those in Thailand.
  • A study was conducted using data from the Thai PCI registry to validate and simplify the CRUSADE score, concluding that both the original and a revised version accurately predicted major bleeding outcomes.
  • The final simplified version of the CRUSADE score, which only incorporates four key factors, also demonstrated strong predictive ability, indicating its effectiveness in the Thai NSTEMI patient population.

Article Abstract

Background: The Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines (CRUSADE) score has been recommended to predict in-hospital bleeding risk in non-ST segment elevation myocardial infarction (NSTEMI) patients. The evaluation of the CRUSADE risk score in Asian patients undergoing contemporary percutaneous coronary intervention (PCI) for NSTEMI is necessary.

Aims: We aimed to validate and update the CRUSADE score to predict in-hospital major bleeding in NSTEMI patients treated with PCI.

Method: The Thai PCI registry is a large, prospective, multicenter PCI registry in Thailand enrolling patients between May 2018 and August 2019. The CRUSADE score was calculated based on 8 predictors including sex, diabetes, prior vascular disease (PVD), congestive heart failure (CHF), creatinine clearance (CrCl), hematocrit, systolic blood pressure, and heart rate (HR). The score was fitted to in-hospital major bleeding using the logistic regression. The original score was revised and updated for simplification.

Results: Of 19,701 patients in the Thai PCI registry, 5976 patients presented with NSTEMI. The CRUSADE score was calculated in 5882 patients who had all variables of the score available. Thirty-five percent were female, with a median age of 65.1 years. The proportion of diabetes, PVD, and CHF was 46%, 7.9%, and 11.2%, respectively. The original and revised models of the CRUSADE risk score had C-statistics of 0.817 (95% CI: 0.762-0.871) and 0.839 (95% CI: 0.789-0.889) respectively. The simplified CRUSADE score which contained only four variables (hematocrit, CrCl, HR, and CHF), had C-statistics of 0.837 (0.787-0.886). The calibration of the recalibrated, revised, and simplified model was optimal.

Conclusions: The full and simplified CRUSADE scores performed well in NSTEMI treated with PCI in Thai population.

Background: The Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria were proposed for predicting bleeding risk in patients undergoing percutaneous coronary intervention (PCI). However, there is a lack of research evaluating the risk of in-hospital bleeding following PCI for acute coronary syndrome (ACS) utilizing the ARC-HBR criteria.

Methods And Results: This study involved 1013 ACS patients who underwent PCI and dual antiplatelet therapy.

Background: Effective treatment of non-ST-segment elevation acute coronary syndromes (NSTEACS) requires careful assessment of both ischaemic and bleeding risks. We aimed to analyse risk distribution and evaluate antiplatelet prescription behaviours in real-life settings.

Methods: Data from 1100 NSTEACS patients in Buenos Aires, Argentina, from the Buenos Aires I Registry, with a 15-month follow-up, were analysed.

Background: The mortality rate of acute coronary syndrome (ACS) remains high. Therefore, patients with ACS should undergo early risk stratification, for which various risk calculation tools are available. However, it remains uncertain whether the predictive performance varies over time between risk calculation tools for different target periods.

Article Synopsis
  • Many patients suffer from complex pain after orthopedic injuries and are at risk of long-term opioid use, highlighting the need for better pain management strategies in trauma care.
  • The study investigates whether personalized pain education and management from coaches can improve pain symptoms, reduce opioid use, and enhance patient-reported outcomes, compared to standard written discharge instructions.
  • Conducted from February 2021 to September 2022, the trial involved 212 patients and assessed the effectiveness of coaching on pain management after orthopedic surgery, focusing on a diverse patient population.

Aim: The aim of this study was to determine the best clinical predictors of acute heart failure needing mechanical ventilation (MV) in the first 48 h of evolution of patients admitted because of acute coronary syndrome (ACS).

Methods: We analyzed a cohort of patients admitted for ACS between February 2017 and February 2018. A pulmonary ultrasound was performed on admission and was considered positive (PE+) when there were three or more B-lines in two quadrants or more of each hemithorax.
