Glycogen Phosphorylase BB: A more Sensitive and Specific Marker than Other Cardiac Markers for Early Diagnosis of Acute Myocardial Infarction.

ABSTRACT: 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 increased in the early hours after AMI. The present study was conducted with the objective to find out the sensitivity and specificity of GPBB over other cardiac markers i.e. myoglobin and CKMB in patients of AMI within 4 h after the onset of chest pain. The study includes 100 AMI patients and 100 normal healthy individuals as controls. In all the cases and controls, serum GPBB and myoglobin concentrations were measured by ELISA where as CK-MB was measured by diagnostic kit supplied by ERBA. The sensitivity and specificity of glycogen phosphorylase BB (GPBB) were greater than CK-MB and myoglobin in patients of AMI within 4 h after the onset of chest pain. Hence, glycogen phosphorylase BB (GPBB) can be used as additional biomarker for the early diagnosis of AMI.

Project description:ObjectiveTo explore the relative association of admission blood glucose levels and antecedent diabetes on early and long-term survival in a contemporary UK population of patients with ST elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI).DesignRetrospective cohort study based on the Myocardial Ischaemia National Audit Project dataset.SettingTertiary care centre.Participants4111 (20.3% known diabetes) consecutive patients admitted with acute myocardial infarction (58.3% STEMI) between October 2002 and September 2008.Primary and secondary outcome measuresAll-cause mortality at 30 days and 1 year. The relative association of admission blood glucose and of antecedent diabetes with mortality was assessed using multivariate Cox regression analysis. Furthermore, we compared these relationships in patients with STEMI to those with NSTEMI.ResultsBy 30 days and 1 year, 409 (9.9%) and 677 (16.5%) of patients died. After adjusting for covariates, diabetes did not show independent association with mortality at any time point, in the entire cohort (HR 30 days 0.93 (95% CI 0.63 to 1.38); 1 year 1.00 (0.77 to 1.30)) or in subgroups of STEMI (HR 30 days 1.03 (0.65 to 1.64); 1 year 1.08 (0.77 to 1.51)) and NSTEMI (HR 30 days 0.62 (0.26 to 1.50); 1 year 0.87 (0.56 to 1.36)). In contrast, after adjusting for covariates, admission glucose showed robust and independent association with mortality in the entire cohort (HR: 30 days 1.07 (1.04 to 1.10); 1 year 1.05 (1.03 to 1.08)), and in the subgroup of STEMI (30 days 1.07 (1.03 to 1.10); 1 year 1.07 (1.04 to 1.10)), and NSTEMI (HR 30 days 1.07 (1.00 to 1.14); 1 year 1.02 (0.97 to 1.06)).ConclusionsAdmission glucose is strongly associated with mortality in all presentations of acute myocardial infarction (AMI), irrespective of established diabetes diagnosis. The increased risk is maintained up to 1 year. Future studies are required to assess the impact of active management of elevated blood glucose in improving mortality in individuals admitted with AMI.
