The present study was designed to investigate the modulatory effects of rottlerin on ischemia reperfusion induced myocardial injury. Isolated rat hearts were exposed to 30 min of global ischemia followed by 120 min of reperfusion using Langendorff apparatus. Myocardial injury was assessed in the terms of infarct size, release of lactate dehydrogenase (LDH), creatine kinase (CK) enzymes. Rottler...

The preventive effects of (-) epicatechin on oxidative stress, cardiac mitochondrial damage, altered membrane bound adenosine triphosphatases and minerals were reported previously in isoproterenol-induced myocardial infarction model. Leakage of lysosomal glycohydrolases and cathepsins play an important role in the pathology of myocardial infarction. This study was aimed to evaluate the preventi...

Myocardial Infarction (MI) is a term which is used for defining the necrosis in the heart muscle due to the lack of the oxygen need of myocardium which cannot be supplied by the coronaries. It is characterized by chest pains or discomfort which may travel into the shoulder, arm, back, neck or jaw [1,2]. Acute myocardial infarction (AMI) is considered more appropriately part of a spectrum referr...

No definitive method of myocardial preservation has been established and conclusions based on experimental data may not be applicable to patients with coronary artery disease. Fifty patients undergoing coronary bypass grafting were randomly assigned to one of two groups for myocardial preservation. In group A cold cardioplegia with external cardiac cooling was used and in group B ischaemic arre...

D iabetes is not only a predisposing factor for cardiovascular disease but once diabetic patients develop coronary artery disease (CAD) they have significantly worse outcomes compared to non-diabetic patients. 2 Diabetes is an independent risk factor for a worse outcome after presentation with acute coronary syndrome (ACS). Prior studies have demonstrated that diabetic patients without previous...

UNLABELLED A 78-year-old women with a recent diagnosis of primary hyperparathyroidism presented with vague chest pain, and new onset left bundle block (LBBB) on the electrocardiogram (ECG) mimicking acute myocardial infarction (AMI). LBBB resolved without abnormal Q waves only after correction of hypercalcemia. The cardiac enzymes, including creatine kinase, creatine kinase-MB, and troponin-I w...

The pathogenesis of acute myocardial infarction is known to be mediated by systemic, intraplaque and myocardial inflammatory processes. Among different immune cell subsets, compelling evidence now indicates a pivotal role for neutrophils in acute coronary syndromes. Neutrophils infiltrate coronary plaques and the infarcted myocardium and mediate tissue damage by releasing matrix-degrading enzym...

The aim of this study was to investigate gamma radiation-induced oxidative damage in erythrocytes after 201Tl myocardial perfusion scintigraphy. Twenty patients (8 women and 12 men) who performed 201Tl myocardial perfusion scintigraphy were included in this study. The blood samples were taken from patients just before, 1 hour after and three hours after injection of the radiopharmaceutical. Mal...

Indigofera cassioides Rottl. Ex. DC. is a large shrub, distributed throughout the hills of India. Because its reported robust antioxidant potential and phytoconstituents content, we were interested in investigating vitro thrombolytic vivo cardioprotective effect methanolic leaves extract cassioides. An model was used to evaluate clot lysis different concentrations along with streptokinase as po...

20(S)-protopanaxadiol (PPD) is an active natural product which transformed from protopanaxadiol-type ginsenosides. The present study was conducted to evaluate the effects of PPD on myocardial ischemia/reperfusion (I/R) injury in a rat model. (20mg/kg) or positive-control drug Diltiazem (10mg/kg) administered daily for 7 days before left anterior descending I/R operation. After 2-hour reperfusio...
