Assessment of myocardial injury by serum tumour necrosis factor alpha measurements in acute myocardial infarction

European Heart Journal
M M HirschlH Sochor

Abstract

Clinical and experimental data have shown that after acute myocardial infarction there is a significant release of tumour necrosis factor alpha. Therefore, an attempt was made to correlate changes in serum tumour necrosis factor alpha concentrations with indices of infarct extent in patients with acute myocardial infarction. In 50 patients with acute myocardial infarction, blood samples for evaluation of tumour necrosis factor alpha and alpha-hydroxybutyrate-dehydrogenase were collected every 6 h until 120 h after admission. Infarct extent was estimated by clinical parameters such as the occurrence of heart failure and rhythm disturbances, by enzymatic methods such as cumulative release of alpha-hydroxybutyrate-dehydrogenase and imaging techniques, by late resting single photon emission tomography--201 thallium scintigraphy--using an extent score and by echocardiography using a wall motion index. The maximum change in serum tumour necrosis factor alpha after infarction (delta TNF) was calculated by subtracting tumour necrosis factor alpha concentration on admission from peak tumour necrosis factor alpha concentration. The average peak tumour necrosis factor alpha level was observed 84 h after admission (median: 12 pg.ml-1). Bet...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
