In the current study, effects of acute short term administration of fructose on cardiac arrhythmias and myocardial infarction size following ischemia/reperfusion were investigated in isolated rat heart. The hearts were subjected to 30 min zero flow global ischemia followed by 120 min reperfusion. In the control group, the hearts were perfused by normal drug free Krebs-Henseleit (K/H) solution t...

left ventricular free wall rupture is responsible for up to 10% of in-hospital deaths following myocardial infarction. it is mainly associated with posterolateral myocardial infarction, and its antemortem diagnosis is rarely made. one of the medical complications of myocardial infarction is the rupture of the free wall, which occurs more frequently in the anterolateral wall in hypertensives, wo...

conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...

introduction: in the present study, potential differences between the effects of l-carnitine (lc) and acetyl-lcarnitine (alc) on ischemia/reperfusion (i/r)-induced myocardial infarction size were investigated. methods: male wistar rats were randomly divided into five groups and then anesthetized by sodium pentobarbital. hearts of the animals were removed and quickly mounted on a langendorff app...

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...

abstract most pheochromocytomas are not suspected clinically while a high percentage of them are curable with surgery. we present the case of an adult cocaine-addicted male patient with an underlying pheochromocytoma and repeated myocardial infarctions. computed tomography showed a left round adrenal mass, also high 24-hour urine levels of catecholamines and metanephrines were detected from uri...

background: increased estimated body iron stores have been recently suggested to be associated with increased risk of acute myocardial infarction (ami); however the question of whether serum ferritin level as an indicator for estimating body iron is an independent risk factor for cardiac events is still questioned. in the present study, we assessed whether serum ferritin was associated with the...

conclusions supervised in-hospital exercise training was associated with improvements in saecg-measured electrical activity post-mi. results cardiac rehabilitation led to significant improvements in qrs duration (p < 0.001), square root of amplitude in the last 40 ms (p < 0.001) and duration of terminal signal with low amplitude (p < 0.001). cardiac rehabilitation also resulted in amelioration ...
