Attenuation of dysfunction in the postischemic 'stunned' myocardium by dimethylthiourea.
The mechanism for the prolonged contractile dysfunction observed in myocardium reperfused after reversible regional ischemia ("stunned" myocardium) is unclear. Recent studies suggest that myocardial stunning may be mediated by oxygen-derived free radicals, but the precise molecular species involved remain unknown. Thus we explored the role of the highly cytotoxic hydroxyl radical in regional po...
متن کاملRecovery of stunned myocardium in acute myocardial infarction quantified by strain rate imaging: a clinical study.
BACKGROUND Strain rate (SR) imaging (SRI) is a tissue Doppler-based method of regional myocardial deformation imaging. The aim of this study was to see whether SRI could quantify changes in myocardial mechanical function after an acute myocardial infarction, and to follow the time course of these changes. METHODS In all, 26 consecutive patients with first-time acute myocardial infarctions wer...
متن کاملThe stunned myocardium: prolonged, postischemic ventricular dysfunction.
Myocardial ischemia has, for many decades, been viewed as an all-or-none process that causes myocardial necrosis when prolonged and severe, but whose effects are transient when it is brief or mild. In view of the evidence that the ischemic process may "hit, run and stun," perhaps our thinking about the consequences of myocardial ischemia should be expanded. According to this formulation, an isc...
متن کاملDetection of stunned myocardium in post-reperfusion cases of acute myocardial infarction.
OBJECTIVE This study was designed to evaluate the correlation between improvements in serial images obtained by SPECT imaging with Tc-99m MIBI (MIBI) and I-123 BMIPP (BMIPP) and the recovery of cardiac function in acute myocardial infarction (AMI) patients after reperfusion therapy. METHODS Twenty five patients who were admitted to the emergency room within 24 hours after the onset of the fir...
متن کاملAcute Anterior Myocardial Infarction Accompanied by Acute Inferior Myocardial Infarction: A Very Rare Coronary Artery Anomaly
Coronary artery anomalies are rare and mostly silent in clinical practice. First manifestation of this congenital abnormality can be devastating as syncope, acute coronary syndrome, and sudden cardiac death. Herein we report a case with coronary artery anomaly complicated with ST segment myocardial infarction in both inferior and anterior walls simultaneously diagnosed during primary percutaneo...
