BACKGROUND The relation between left ventricular (LV) remodeling and ventricular arrhythmias after myocardial infarction is poorly documented. We investigated the relations between LV size, hypertrophy, and function and ventricular arrhythmias in 263 patients from the Survival and Ventricular Enlargement (SAVE) study, using quantitative 2D echocardiography and ambulatory ECG monitoring after my...
Acute myocardial infarction is a frequent and disabling disease. Ischemic postconditioning, consisting of repeated brief cycles of ischemia-reperfusion performed immediately after reperfusion following a prolonged ischemic insult, dramatically reduces infarct size in experimental models. A recent clinical study demonstrated that repeated brief episodes of inflation-deflation of the angioplasty ...
Background It has been reported that hyperintensity on T2W-CMR represents the area-at-risk. This conclusion is based upon the observation that the region of T2-hyperintensity is always larger than region of infarction. However, differences in measured size may be due to many factors, including the choice of different image intensity thresholds (Nat Rev Cardiol. 2010 Oct;7(10):547-9.). Additiona...
BACKGROUND Studies on the impact of time to treatment on myocardial infarct size have yielded conflicting results. In this study of ST-Elevation Myocardial Infarction (STEMI) treated with primary percutaneous coronary intervention (PCI), we set out to investigate the relationship between the time from First Medical Contact (FMC) to the demonstration of an open infarct related artery (IRA) and f...
OBJECTIVE To evaluate the differences between three methods for the measurement of experimental infarction in rats in comparison to the traditional method. METHODS Histological analysis of the infarction area (AREA), histological analysis of the internal cavity perimeter (PER) and echocardiogram analysis of the internal perimeter (ECHO) were compared to the traditional method (histological an...
Effects of Doxycycline on Cx43 Distribution and Cardiac Arrhythmia Susceptibility of Rats after Myocardial Infarction Abstract: This study aimed to observe the effects of doxycycline (DOX) on gap junction remodeling after MI and the susceptibility of rats to cardiac arrhythmia. The proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal...
