Can Pre-Hospital Use of the HEART Score and Abbott i-STAT® Point-of-Care Troponin Predict Major Adverse Cardiovascular Events: the PARA-HEART Pilot Implementation

Detailed Summary

Approximately 8-10 million patients complaining of chest pain present to an Emergency Department (ED) annually in the United States. These patients are a challenge to healthcare providers, who are tasked with determining whether these symptoms are due to an acute coronary syndrome (ACS) or a non-ACS cause.In an effort to improve the quality and value of care for patients with acute chest pain, our group recently validated a risk stratification pathway, the HEART Pathway, which is designed to focus cardiac testing and admissions on higher-risk patients, who are more likely to benefit from testing.While the HEART score has been well validated in the ED setting, it has yet to be implemented in a prehospital setting. Paramedics are often the first providers to evaluate and begin treating patients with symptoms concerning for ACS. Current pre-hospital risk stratification is largely based on a combination of ECG results and paramedic gestalt. Since ECGs without signs of a STEMI (ST-segment elevation myocardial infarction) are poor predictors of ACS, paramedics often have difficulty distinguishing high-risk patients from low-risk patients.Thus, multidisciplinary leaders within Emergency Medicine, Cardiology, and Prehospital Medicine have agreed that a limited/pilot evaluation of the HEART Score with Abbott's i-STAT® point-of-care (POC) troponin testing in the prehospital setting is needed. To establish the feasibility and accuracy of HEART score and POC testing in the prehospital setting the investigators propose a quality surveillance study of a limited implementation of the HEART score with POC troponin testing.
