Accumulated creatine kinase MB isoenzyme release (sigma CK-MB) during acute myocardial infarction was correlated with biplane left ventricular (LV) angiographic estimates of percent abnormally contracting segment (%ACS) and ejection fraction (EF) in 35 patients who underwent diagnostic angiography at a mean of 33 +/- 4 days post myocardial infarction (MI). Of the 35 patients, 18 had no evidence...

BACKGROUND Characteristics of the ventricular fibrillation (VF) waveform reflect arrest duration and have been incorporated in studies on algorithms to guide resuscitative interventions. Findings in animals indicate that VF characteristics are also affected by the presence of a previous myocardial infarction (MI). As studies in humans are scarce, we assessed the impact of a previous MI on VF ch...

Background: Analog recordings of data are used in many fields and it is often important to determine if portions of a recording deviate from normal. In many cases, the accurate interpretation of analog recordings is time-consuming and requires considerable skill and experience. The present paper describes a statistics-based method for quickly detecting possible abnormalities in analog tracings ...

This study provides data on a consecutive series of 179 survivors of acute myocardial infarction (MI) who had symptom-limited treadmill exercise testing, coronary angiography and left ventriculography within 6--8 weeks after infarction. No patient died. The prevalence of multivessel disease was higher in the symptomatic survivors (79%) (p less than 0.001). The prevalence of multivessel disease ...

BACKGROUND Early diagnosis of right ventricle (RV) involvement in inferior myocardial infarction (Inf MI) is very critical. This study was performed to evaluate the clinical findings of Inf MI with or without RV infarction. METHODS From September 2010 to September 2012, 195 patients with definite diagnosis of Inf MI were evaluated in the Department of Cardiology, in Babol, north of Iran. The ...

⎯Brain activation during motor imagery (MI) has been studied extensively for years. Based on studies of brain activations of MI, in present study, a complex finger tapping imagery and execution experiment is designed to test the brain activation during MI. The experiment results show that during MI, brain activation exists mainly in the supplementary motor area (SMA) and precentral area where t...

Background—Mitral regurgitation (MR) generally accompanies inferobasal myocardial infarction (MI), with leaflet tethering by displaced papillary muscles. Mitral regurgitation is also reported with anteroapical MI without global dilatation or inferior wall motion abnormalities. We hypothesized that anteroapical MI extending to the inferior apex displaces the papillary muscles, tethering the mitr...
