tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute st elevation myocardial infarction (stemi). the primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly f...

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 the consequence o...

Myocardial necrosis can be result from a number of causes including nutritional deficiencies, chemical and plant toxins, ischemia and metabolic disorder. The outcome of myocardial necrosis varies depending on the extent of the damage (Donald 2001, Jubb 1993, Radostits 1994, Vanvaleet 1986). Myocardial infarction without demonstrable of atherosclerosis were reported in a rhesus macaque (Gonder 1...

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...

in the present study,cardioprotective effect of aqueous extract of garcinia indica linn. fruit rinds in isoprenaline-induced myocardial infarction in wistar albino rats was evaluated. in vitro total phenolic, total flavonoid content and 2, 2’-diphenyl-1-picrylhydrazyl hydrate radical scavenging activity was measured. in vivo effect of aqueous extract of g. indica was evaluated in wistar albino ...

Cardiac diseases are common post-stroke and are associated with increased morbidity and mortality. One possible mechanism of acute cardiac injury is the neurogenic myocardial damage, where the cerebral injury is disturbing the normal sympathetic and parasympathetic neuronal outflow to the heart leading to cardiac damage including myocardial infarctions. The exact mechanism is not completely und...

Introduction: Regarding the association between climate, seasons and myocardial infarction, a cross-sectional study was carried out in Shiraz and Bandar Abbas in Iran. Methods: All patients with diagnosis of acute myocardial infarction living in Shiraz and Bandar Abbas were included in the study during 2011-2013. Demographic data were extracted from the patients’ hospital records. Data w...

Background: Cardiac complications due to iron overload are the most common cause of death in patients with thalassemia major. The aim of this study was to compare iron chelation effects of deferoxamine, deferasirox, and combination of deferoxamine and deferiprone on cardiac and liver iron load measured by T2* MRI. Methods: In this study, 108 patients with thalassemia major aged over 10 years...

conclusions there was no meaningful relationship between the mortality rate of patients with mi who were either opium-dependent or non-opium-dependent. the number of re-hospitalizations due to heart problems was meaningfully higher in the opium-dependent patients; hence, educating people and training them on the destructive effects of opium, specifically in patients with heart conditions is hig...
