AI Article Synopsis
- The study evaluated the safety of an outpatient chest pain pathway (OCPP) for emergency department patients with HEART scores of 4 or 5.
- Implementing the OCPP led to a decrease in hospital admissions for these patients and maintained low rates of acute myocardial infarction (AMI) and death compared to pre-OCPP periods.
- The OCPP demonstrated non-inferior outcomes, suggesting it is a safe alternative to traditional care for managing these patients.
Article Abstract
Objective: This study aims to assess the safety of an outpatient chest pain pathway (OCPP) for patients presenting to the emergency department (ED) with chest pain and a HEART score of 4 or 5.
Methods: This is a retrospective, observational, non-inferiority study assessing the impact of the OCPP on the management and outcomes of ED patients with HEART score of 4 or 5. The study compared patients evaluated in the pre-OCPP (January‒May 2018) and the post-OCPP period (January‒October 2022). Data were collected via non-blinded chart review. The primary outcome was the rate of acute myocardial infarction (AMI) and death in patients utilizing the OCPP compared to patients with HEART score 4 or 5 in 2018. Secondary outcomes included admission rates before and after the implementation of this pathway. Non-inferiority of the post-intervention study epoch for the AMI/death composite outcome was assessed via the two one-sided tests (TOST), procedure.
Results: After implementing the OCPP, rates of patients with ED HEART score of 4 or 5 admitted from the ED decreased from 85.1% (605/711) to 74.1% (1239/1671) in 2022. Of the 432 total patients discharged in 2022, 237 (54.6%) patients were referred to emergent cardiology follow-up via the OCPP. The 30-day rate of AMI/death for patients discharged via the OCPP was 0.4% (1/237), as compared to 2.2% (8/368) in 2018. When compared to rates of AMI/death for all patients with HEART score 4 or 5 in 2018, outcomes for OCPP patients were found to be non-inferior.
Conclusion: The OCPP resulted in non-inferior rates of AMI/death in patients with HEART scores of 4 or 5 as compared to usual care.

Assessing modified HEART scores with high-sensitivity troponin for low-risk chest pain in the emergency department.

The accuracy of using HEART (history, electrocardiogram, age, risk factors, and troponin) scores with high-sensitivity cardiac troponin (hs-cTn) to risk stratify emergency department (ED) chest pain patients remains uncertain. We aim to compare the performance accuracy of determining major adverse cardiac event (MACE) among three modified HEART (mHEART) scores with the use of hs-cTn to risk stratify ED chest pain patients. This retrospective single-center observational study included ED patients with suspected acute coronary syndrome who had HEAR scores calculated and at least one hs-cTnI result.

Background: Noninferiority of omitting intraoperative defibrillation threshold (DFT) testing has been documented for transvenous implantable cardioverter defibrillators (ICD) whereas data for the subcutaneous-ICD (S-ICD) regarding the need for DFT testing, especially during S-ICD generator replacement, is not available.
Methods: A total of 112 consecutive patients who underwent S-ICD generator replacement and routine testing were included in this retrospective single-center study and analyzed regarding the outcome of intraoperative DFT.
Results: The majority of patients (87.

Background: The Charlson Comorbidity Index (CCI) is a frequently used mortality predictor based on a scoring system for the number and type of patient comorbidities health researchers have used since the late 1980s. The initial purpose of the CCI was to classify comorbid conditions, which could alter the risk of patient mortality within a 1-year time frame. However, the CCI may not accurately reflect risk among American Indians because they are a small proportion of the US population and possibly lack representation in the original patient cohort.
