phosphorylase/infarction

The activity of glycogen phosphorylase (GP) and creatine phosphokinase isoenzyme MB (CPK MB) was measured in patients with myocardial infarction over 72 hours after the anginal attack. In most clinical observations, CPK MB and GP patterns were similar, however, the GP activity reached its peak 4-6

Distinct differences in activity of glycogen phosphorylase were not observed in various parts of an intact human myocardium. This enzymatic activity vas considerably decreased in the left ventricle of the myocardium impaired by infarction; with prolongation of the infarction period the enzymatic

Methods are described (a) for the estimation of glycogen phosphorylase activity (EC 2.4.1.1) in human blood serum based on the chemical determination of liberated orthophosphate or on the enzymic determination of glucose 1-phosphate in a coupled assay system and (b) for the electrophoretic

Early experimental and clinical reports on glycogen phosphorylase BB (GPBB) kinetics following myocardial ischemic injury suggested that it could be a useful diagnostic marker for early detection of acute myocardial infarction (AMI). After more than two decades of investigation, there is now

Cardiac markers are used to evaluate functions of heart. However, there are no satisfactory cardiac biomarkers for the diagnosis of acute myocardial infarction (AMI) within 4 h of onset of chest pain. Among novel cardiac markers, glycogen phosphorylase BB (GPBB) is of particular interest as it is

This review deals with glycogen phosphorylase (GP) and its isoenzyme BB in the diagnosis of ischaemic myocardial injury. Early identification and confirmation of acute myocardial infarction is essential for correct patient care and disposition decision in the emergency department. In this respect,

OBJECTIVE To investigate the association between methylthioadenosine phosphorylase (MTAP) gene single nucleotide polymorphisms (SNP) and myocardial infarction (MI) in the Chinese Han ethnicity. METHODS 432 patients suffered from myocardial infarction and 430 controls were involved for case and

BACKGROUND This study aimed to assess whether heart fatty acid-binding protein (H-FABP) and glycogen phosphorylase isoenzyme BB (GPBB) could be used for the accurate diagnosis of acute myocardial infarction (AMI) in acute coronary syndrome (ACS) patients. METHODS The study included 108 ACS patients

BACKGROUND Early diagnosis is crucial for management of patients with suspected acute myocardial infarction (AMI). Among innovative and promising biomarkers, the recent interest raised on glycogen phosphorylase isoenzyme BB (GPBB) has prompted us to perform a meta-analysis of published

On the basis of a small number of patients with the tentative diagnosis acute myocardial infarction the diagnostic valency of the glycogen phosphorylase was tested. A separation between severe stenocardia and myocardial infarction is possible. After simplification of the methodology the glycogen
