To minimize the risk of further heart attacks, a doctor will usually recommend lifestyle changes, such as quitting smoking, losing weight, getting more exercise, and eating a more nutritious diet.Ī person will likely receive different treatments if their high troponin levels are due to a different cause. ablation, which is a treatment that destroys certain heart cells using radio waves.bypass surgery, which involves a surgeon creating new pathways for blood to travel through to the heart muscle.the insertion of a wire mesh tube to prop open a blocked blood vessel during an angioplasty.coronary angioplasty, which is a procedure that involves threading a small balloon into the coronary artery.Some common treatments following a heart attack include: The treatment for a heart attack depends on whether the blockage preventing blood flow to the heart is partial or complete. Very high levels of troponin usually indicate that a person has recently had a heart attack. This suggests that prehospital i-STAT POC cTn could be useful to rule-in MI, but should not be used to exclude MI.Ĭhest pain myocardial infarction point-of-care prehospital troponin.High troponin levels are a symptom, not a diagnosis, so treatment will focus on finding and addressing the underlying cause. Conclusions: Prehospital POC i-STAT cTn measurement in patients transported with acute chest pain was highly specific for MI but had low sensitivity. Compared to POC cTn, the central lab cTn measurement of prehospital blood resulted in a higher sensitivity of 67.9% (95% CI 53.7-80.1%, p < 0.0001), but lower specificity of 92.4% (95% CI 88.4-95.4%, p = 0.0001). The specificity and positive predictive value of the POC cTn measurement were 99.2% (95% CI 97.5-99.8%) and 85.7% (95% CI 63.7-97.0%) for MI. MI was adjudicated in 16.2% (68/421) during the index visit. Results: During the study period prehospital POC cTn results were obtained on 421 patients, of which 5.0% (21/421) had results >99th percentile upper reference limit. Test characteristics (sensitivity, specificity, and predictive values) for detection of MI were calculated for POC and central lab cTn measurement of prehospital blood and compared with McNemar's test. Index visit MI was adjudicated by 3 experts using central lab cTn measures from the patient's clinical blood draws. Blood collected during ambulance transport was also analyzed for cTn in the central lab. Following ED arrival, participants received standard evaluations including clinical blood draws for cTn measurement in the hospital central lab (AccuTnI +3 assay Beckman Coulter, or cTnI-Ultra assay Siemens). During ambulance transport paramedics initiated intravenous access, collected blood, and used a POC device (i-STAT Abbott Laboratories) to measure cTn. Patients with ST-elevation MI on ECG were excluded. Methods: A prospective cohort study of adults with non-traumatic chest pain was conducted in three Emergency Medical Services agencies (December 2016 to January 2018). The objective of this study was to prospectively test the performance of POC cTn measurement by paramedics to detect myocardial infarction (MI) among patients transported to the ED for acute chest pain. However, data examining POC cTn measurement in the prehospital setting, during ambulance transport, are limited. Objective: Use of point-of-care (POC) troponin (cTn) testing in the Emergency Department (ED) is well established.
