The measurement of cardiac troponins, either cardiac troponin I or T, has become the culprit of clinical decision making in patients with suspected acute coronary syndrome (ACS), especially in those with non-ST elevation myocardial infarction (NSTEMI).
To assess (1) correlation between maximum corrected QT interval (QTc) and cardiac Troponin I (cTnI) levels; (2) if prolonged corrected QT interval is an independent predictor of higher MACE in NSTEMI patients.
In this study population of patients with acute ischemic stroke (<i>n</i> = 178), acute ST-segment elevation myocardial infarction (<i>n</i> = 35), and acute non-ST-elevation myocardial infarction (<i>n</i> = 35), patients with acute ischemic stroke with elevated cTnI comprised 18.5% of subjects.
Eight patients (8 of 100; 8%) experienced new high-sensitivity cardiac troponin I elevation after electroconvulsive therapy with a cumulative incidence of 3.7% (9 of 245 treatments; one patient had two high-sensitivity cardiac troponin I elevations), two of whom had a non-ST-elevation myocardial infarction (incidence 2 of 245; 0.8%).
