An elevated troponin level should be assessed along with signs and symptoms, and cardiac diagnostic tests. ConclusionĪn elevated troponin level does not necessarily mean that you are having a cardiac event. Researchers investigated 20,000 patients at the University Hospital Southampton that were undergoing lab tests for troponin.Īlso, if you are taking biotin, just know that biotin can cause falsely elevated troponin. The troponin level, which is the gold standard test for detecting a heart attack can be misleading according to researchers. The first line of defense against heart disease is to monitor your blood pressure. If the troponin 1 range is abnormal, the nurse will immediately notify the physician. The nurse oftentimes is the first professional to look at labs, and the first lab they will look at is the Troponin 1 levels. These protocols involved testing for Troponin 1 levels. The nurse usually has standards of care when someone comes in with chest pain. When a patient comes into the emergency room complaining of chest pain, the nurse is usually the first professional that the person comes in contact with. Nurses are usually the first professionals to draw the labs and to look at the results. This book titled Cardiovascular Care Made Easy is an excellent book on cardiac nursing. It is very important for nurses to know about elevated troponin and its relationship to heart muscle damage. Any delay results in heart muscle damage. The Troponin T-test is a little more expensive, but it is worth the extra cost because it detects heart damage earlier. When doctors used the conventional Troponin and the Troponin T-test, 5% more heart attacks were detected with the troponin T-test.Įlevated troponin levels usually indicate cells in part of the heart have died from lack of oxygen. Kidney failure- this is the second most common reason for elevated troponinĪ highly sensitive test called Troponin T has been developed to detect more cardiac infarctions or heart attacks.What Can Cause Troponin Levels to Be Elevated?Īlthough the majority of time troponin levels are elevated because of heart muscle damage, sometimes there are other reasons. To sum it up, elevated troponin levels are a powerful indicator of cardiac muscle damage. Many times if the elevated troponin is not related to cardiac issues, it is related to renal issues. Excluding the diagnosis of acute coronary syndromes Explaining troponin. These values do not apply to results that are converted to other units of measure. It the EKG is negative, and the patient shows no other signs of a heart attack, the provider will start to look at other reasons for the elevated troponin. Applies only to results expressed in units of measure originally reported by the performing laboratory. If the troponin level comes back elevated, along with other positive diagnostic tests, the provider will initiate a heart attack protocol. The i-STAT POC cTnI assay can be added to the list of assays for risk stratification.When a patient comes into the emergency department with chest pain, the healthcare providers will immediately order a serum troponin level. reference concentrations before 30 days for ACD, MI or ACD, and MI or cardiac death. Kaplan-Meier curves showed early separation between patients with increased vs. Odds ratios and 95% confidence intervals for all-cause death (ACD), MI or ACD, MI or cardiac death, and cardiac death at 60 days were all statistically significant after adjustment for age, diabetes, hypertension, and history of renal failure as follows: 2.54 (1.24-5.20), P = 0.009 2.76 (1.37-5.58), P = 0.003 5.98 (1.65-21.7), P = 0.008 and 2.54 (1.24-5.20), P = 0.009. We computed survival and event curves with the Kaplan-Meier method and compared risk stratification groups with the log-rank test.Īcute myocardial infarction (MI) was diagnosed in 8.1% of patients. Patients were risk-stratified based on cTnI concentrations defined by the predetermined 99th percentile reference limit for plasma (0.04 microg/L). We measured plasma cTnI with the i-STAT assay. We studied consecutive patients (n = 367) presenting with symptoms suggestive of ACS who were admitted through the emergency department. We investigated the use of a POC cTnI assay in ACS patients. Few studies have investigated the role of cardiac troponin point-of-care (POC) testing for predicting adverse outcomes in acute coronary syndrome (ACS) patients.
