title: Mechanism of troponin elevations in patients with acute ischemic stroke.
abstract: Ischemic heart disease and cerebrovascular diseases frequently co-exist in the same patient, and similar risk factors are shared. For 60 years, experimental, observational, and clinical trial data have incessantly indicated that neurologically induced myocardial injury exists. Since the introduction of troponin in the diagnosis of acute myocardial infarction, this marker has been measured in a number of other conditions as well. One of these conditions is acute ischemic stroke, causing diagnostic dilemmas for clinicians. Because various electrocardiographic alterations have also been reported in these patients, it has been suggested that elevated troponin levels are somehow neurologically mediated, thus not caused by direct cardiac release. In conclusion, this review examines the available studies that systematically measured troponin in patients with acute ischemic stroke to properly interpret troponin elevations in these patients.
