Objective(s):To examine the expressions of CD11a, CD11b, and CD11c integrins in the myocardial tissues of rats with isoproterenol-induced myocardial hypertrophy. This study also provided morphological data to investigate the signal transduction mechanisms of myocardial hypertrophy and reverse it. Materials and Methods: A myocardial hypertrophy model was established by subcutaneously injecting i...

it is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ecg-gated is an appropriate method for this purpose. the aim of this study was to compare the results of myocardial perfusion a...

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...

background: standard methods for the measurement of myocardial perfusion are invasive and require cardiac catheterization or the use of radioisotope dyes. the coronary sinus blood flow (csbf) is an appropriate criterion for the efficacy of myocardial perfusion. this study sought to measure csbf via transthoracic echocardiography (tte) in patients with acute myocardial infarction (ami) and to as...

Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be...

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 ...

introduction: the relationship between depression and coronary artery disease is well established; however assessment of this relationship using functional and semi-quantitative imaging (myocardial perfusion scintigraphy) was lacking. the aim of this study was to assess the relationship between the severity of depression and the severity of myocardial perfusion abnormality. methods: patients we...
