Relationsip Between Oxidative Stress and QT Dispersion in Patients With Acute ST Segment Elevation Myocardial Infarction Treated With N-acetylcysteine

Abstract

The aim of this study was to assess the effect of N-acetylcysteine (NAC) treatment, as an adjunct therapy in myocardial infarction on oxidative stress, infarct size and dispersion of QT. Patients with acute myocardial infarction received either 15 mgc of NAC infused intravenously over 24 hours (n=15) or no NAC (n=15), combined along with streptokinase. In order to assess the oxidative stres, plasma malondialdehyde (MDA) level was measured at admission and after 4 and 24 hours. For all patients, QT dispersion (QTd) and Bazett rate corrected QTc dispersion (QTcd) were measured from a high quality 12 lead ECG recorded at 50 mm/s on admission, at 4 and 24 hours. Coronary angiography were performed to assess reperfusion. At admission, plasma MDA levels were not different between the groups. In the NAC treated patients percent plasma MDA changes according to the baseline decreased whereas in the NAC non-treated patients percent MDA changes increased at 4 and 24 hours (p=0.001 and p=0.0001, respectively). Significant decreases in the percent QTd (p=0,04) and QTcd (p=0.03) period changes were observed in patients treated with NAC compaired to patients treated without NAC at 24 hours. N-acetylcysteine treatment reduces lipid peroxidation during ischemia and reperfusion and decreases QT dispersion.
