To evaluate the application of radionuclide infarct scintigraphy to diagnose myocardial infarction after revascularization, we obtained postoperative technetium 99m pyrophosphate myocardial scintigrams, serial electrocardiograms and CPK-MB isoenzymes in ten control and 51 revascularized patients. All control patients had negative electrocardiograms and scintigrams, but eight had positive isoenz...

Experimental myocardial infarction was produced in 32 mongrel dogs. The changes in activity of four lysosomal enzymes (acid phosphatase, glucuronidase, deoxyribonuclease, and •y-glutamyl-transpeptidase) were examined in the soluble and the particle-bound fraction. The pattern of changes in free and particle-bound enzyme activity observed was similar for all four enzymes. During the first 48 hou...

objective(s) several studies have reported improved response of exercised hearts to myocardial infarction (mi). this study was aimed to evaluate the preventive role of treadmill exercise and diosgenin on cardiac marker enzymes, thiobarbituric acid reactive substances (tbars), total antioxidant status (tas), lipids, and electrocardiographic (ecg) patterns in isoproterenol (iso)-induced myocardia...

Cardiac diastolic dysfunction has emerged as a growing type of heart failure. The present study aims to explore whether Qiliqiangxin (QL) can benefit cardiac diastolic function in spontaneously hypertensive rat (SHR) through enhancement of cardiac glucose metabolism. Fifteen 12-month-old male SHRs were randomly divided into QL-treated, olmesartan-treated, and saline-treated groups. Age-matched ...

We have read with great interest the recent and interesting contribution by Dr. Francia et al. about a case of late cardiac tamponade due to myocardial contusion. We would like to make certain observations regarding a similar case that we have recently treated. A 70-year-old woman came to our emergency department after having undergone the Heimlich maneuver because of choking. Upon admittance, ...

myocardial infarction (mi) is one of the most important health burdens worldwide. aspirin as an non- steroid anti—inflammatory drug, has been proven to be a protective factor to decrease the incidence, however its effect of mi size is still unknown. we designed this study to compare the biomarkers after mi in patients with and without aspirin intake. 378 patients were enrolled and the results s...

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...

INTRODUCTION Eosinophilic myocarditis is a rare form of myocarditis. It is characterized pathologically by diffuse or focal myocardial inflammation with eosinophilic infiltration, often in association with peripheral blood eosinophilia. We report a case of eosinophilic myocarditis secondary to hypereosinophilic syndrome. CASE PRESENTATION A 74-year-old Caucasian woman with a history of asthma...

AIMS Membrane bound adenosine triphosphatases (ATPases) and lysosomal enzymes play an important role in the pathology of myocardial infarction. This study was aimed to evaluate the combined preventive effects of quercetin and alpha-tocopherol on membrane bound ATPases and lysosomal enzymes in isoproterenol induced myocardial infarcted rats. MAIN METHODS Male Wistar rats were pretreated with a...

Normal rats pre-treated with P. kurroa (200 mg/kg) alone did not showed significant change, however, isoproterenol (ISP) administration resulted in hemodynamic and left ventricular dysfunction, oxidative stress, and lipid peroxidation. Such cardiac dysfunction was significantly prevented by P. kurroa root extract pre-treatment. Pre-treatment significantly attenuated the ISP-induced oxidative st...
