Feras Almarshad1 and Ghulam Mustafa2
ABSTRACT
Objective: To evaluate the prehospital point-of-care troponin testing and paramedic risk stratification within existing chest pain care pathways reveals promising reliability and validity, suggesting their potential as valuable tools in enhancing early cardiac assessment and improving patient outcomes.
Study Design: Prospective study
Place and Duration of Study: This study was conducted at the Department of Medicine, Nishtar Medical University, Multan, from February 2021 to January 2022.
Methods: Study included 400 consecutive patients experiencing acute chest pain categorized as emergencies. All patients were transported to the hospital via ambulance for subsequent medical care. Positive TnT test prehospital and at the time of hospital admission were compared. Main variables of study were values of troponin test in myocardial infarction associated chest pain patients at hospital and during emergency travelling and previous history coronary artery disease, myocardial infarction and risk factors like diabetes, smoking and hypertension.
Results: Myocardial infarction was positive in 32.0% in chest pain patients. Prehospital troponin was positive in 33 (8.3%) patients. Troponin test was positive in 53.8% patients at admission. The sensitivity for prehospital troponin to myocardial infarction was 18.0% and the sensitivity to myocardial infarction for in-hospital troponin was 74.2% with specificity 96.3% and 55.9%, respectively. (p<0.001).
Conclusion: In regions where patient transport times are brief, the point-of-care rapid Troponin T (TnT) test reveals only a minority of individuals experiencing chest associated, prehospital TnT test positive outcome emerges as an objective indicator for a more adverse prognosis in those with suspected heart attacks.
