We compared the clinical performance of measuring creatine kinase (EC 2.7.3.2) isoenzyme MB by use of an enzyme immunoassay (Enzygnost CK-MB, Behring Diagnostics) with an immunoprecipitation method (Isomune-CK, Roche Diagnostics) for the diagnosis of acute myocardial infarction. Sera from 80 patients admitted to the coronary care unit because of chest pain were examined: 40 who had this diagnos...

Hydroxypyruvate has been shown to be an alternative substrate for lactate dehydrogenase. The clinical value of this “glycerate dehydrogenase’ has been investigated on 60 patients admitted to the hospital with a provisional diagnosis of myocardial infarction. For comparison, lactate dehyd rogenase, a-hydroxybutyric dehyd rogenase, creatine kinase, aspartate transaminase, and alanine transaminase...

introduction: the aim of this study was to evaluate the effect of successful kidney transplantation (kt) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-spect) in patients suffering from end-stage renal disease. ...

abstract introduction: myocardial ischemia, cerebral ischemia and myocardial infarction are the most important complications of hypertension and atherosclerotic disease in developing countries. angiotensin converting enzyme (ace) inhibitors are among the drugs used to treat hypertension and heart failure. captopril is an ace-inhibitor which also has antioxidant properties. this study was conduc...

Serial plasma determinations of the isoenzymes of CPK were performed in all patients (376) admitted to a coronary care unit during a 12-month period with diagnosis of possible acute myocardial infarction. Results were compared with data from other enzyme studies and from the electrocardiogram. An attempt was made to determine the incidence of falsely positive CPK-MB (myocardial-specific form). ...

We report a case of silent acute ST-elevation myocardial infarction associated with amphetamine use in a 62 years old diabetic man. The patient was devoid of chest pain and had a normal cardiac enzyme analysis at the initial presentation. A routine electrocardiogram demonstrated acute inferior wall ST-elevation myocardial infarction. Coronary angiography confirmed a total occlusion of the poste...

In 15 patients with chronic left ventricular failure caused by ischaemic heart disease, cardiac output and right heart pressures were measured before and after the oral angiotensin-converting enzyme inhibitor, captopril, which was administered in increasing doses. In 12 of 15 patients, coronary blood flow, and in 11 patients myocardial oxygen extraction and consumption and lactate extraction we...

statement of the problem periodontitis is a common infectious disease that can be affected by different factors.periodontal conditions can be influenced by systemic diseases and they also can act as risk factors for some systemic diseases. several studies have been carried out on the relationship between cardiovascular disease and periodontal disease. purpose the purpose of our study was to eva...

Mature male Sprague-Dawley rats were subjected to an isoproterenol-induced myocardial infarction. Animals were sacrificed on a daily basis in order to assess the temporal changes in prolyl hydroxylase activity and collagen metabolism during the acute stages of myocardial necrosis and repair. Total myocardial hydroxyproline, as an indexof collagen content, increased promptly and markedly, beginn...

has led to an appreciation of the clinical importance of achieving regression of cardiac hypertrophy, as well as control of blood pressure, in patients receiving antihypertensive therapy. The superiority of converting enzymeinhibitors compared to other antihypertensive agents in effecting regression of cardiac hypertrophy could be attributable to their characteristic profile of actions. By inhi...
