An elderly female cruise ship passenger developed chest pain shortly after an emotionally charged incident involving shipboard authorities. The electrocardiogram and cardiac enzyme profile were indicative of myocardial infarction but the final diagnosis, established after aeromedical evacuation, was stress-related cardiomyopathy. This case is an example of a relatively unknown clinical entity t...

I n 1954, LaDue et al' first noted rises in serum glutamic oxaloacetic transaminase (SGOT) enzyme levels following myocardial infarction. This important observation led to the evaluation of this and other serum enzyme systems as specific and sensitive mdi-cators of myocardial infarction. Elevation of serum creatine phosphokinase (CPK) appeared to be a more sensitive conventional serum enzyme cr...

Myocardial infarction is one potential outcome after an electric shock though it is seen relatively rarely. Nonetheless, an increased death rate because of cardiopulmonary arrest is of concern and merits careful scrutiny. Here, we report a man with myocardial infarction following electrical shock. Although he had frankly normal coronary arteries by coronary angiography, myocardial infarction wa...

Isoproterenol (ISPH) induced myocardial infarction was confirmed by disturbances in serum and heart tissue marker enzymes such as lactate dehydrogenase (LDH), creatine phospho kinase (CPK), aspartate transaminase (AST) and alanine transaminase (ALT), increased level of lipid peroxidation and histopathological changes in the heart of ISPH administered rats. Pretreatment with mangiferin (10 mg/10...

Periprocedural myocardial infarction is a potential problem of percutaneous coronary intervention. Even after seemingly uncomplicated, straightforward elective coronary interventions, elevation of cardiac enzymes can be observed and occur in approximately one-third of cases (1). Such enzyme elevations have been shown to be associated with myocardial injury, for example, by magnetic resonance st...

introduction: inhibition of renin angiotensin system represents an important approach in the management of cardiovascular diseases. the aim of this study was to explore the effects of pretreatment with non-hypotensive dose of angiotensin converting enzyme (ace) inhibitor, ramiprilat and angiotensin type 1 (at1) receptor blocker, losartan on myocardial infarct size and arrhythmias in a rat model...

Background Angiotensin converting enzyme-2 (ACE2) is an analogue of the ACE that cleaves Angiotensin II to Angiotensin 1-7, a peptide with vasodilatory properties. Previous studies showed increased ACE2 activity among patients with chronic heart failure. ACE2 activity has been shown to correlate with the NYHA functional class in this setting, suggesting a compensatory role in advanced heart fai...

We examined for myocardial ischemia induced by continuous inhalation of fenoterol in children with severe acute asthma. Thirty children with severe acute asthma were evaluated for signs of myocardial ischemia when treated with 0.5 mg kg dose (maximum 15 mg) of inhaled fenoterol for one hour. The heart rate was measured before and after inhalation. Cardiac enzymes (creatine kinase, creatine kina...

OBJECTIVES A myocardial calcium-independent PLA2 has been described that is activated during myocardial ischemia and this enzyme may modulate ATP-sensitive potassium channels (KATP). The aim of this study was to determine the effect of an inhibitor of this enzyme, a bromoenol lactone, in isolated globally ischemic rat hearts. METHODS Isolated rat hearts were treated for 10 min with 0.3-6 micr...
