ABSTRACT
Background: Diabetes mellitus is one of the most important risk factors of coronary artery disease. Admission hyperglycemia adversely influences the outcome of acute coronary syndrome patients. The study was conducted to compare the various diagnostic methods for the detection of undiagnosed diabetes mellitus in acute coronary syndrome patients with admission hyperglycaemia in Bangladeshi population. Methods: It was a cross sectional comparative study involving 157 patients with admission blood glucose level e”7.8 mmol/l. Fasting plasma glucose, Glycated haemoglobin, pre-discharge oral glucose tolerance test was measured in all subjects and comparison of performance of different methods was done. Results: Oral glucose tolerance test revealed that in spite of admission hyperglycaemia, 57 (36.3%) patients were diabetic and 52 (33.12%) patients had impaired glucose homeostasis and 48 (30.57%) patients had normal glucose metabolism. Undiagnosed diabetes could not be adequately predicted with admission plasma glucose, fasting plasma glucose or HbA1c alone (area under the ROC curve 0.589, 0.825 and 0.852 respectively). Conclusion: Admission hyperglycaemia does not diagnose diabetes reliably in a stressful condition like acute coronary syndrome. Although neither admission plasma glucose, fasting plasma glucose, nor HbA1c level were as good as oral glucose tolerance test in detecting true diabetes, but combined fasting plasma glucose & HbA1c were found to be more sensitive & specific screening tool for detecting unknown diabetes in acute coronary syndrome patients with admission hyperglycaemia.
ABSTRACT
Background: Epidemiological transition which is taking place in every part of the world, among all races, ethnic groups and cultures has resulted in the global rise in cardiovascular disease (CVD). Cardiovascular disease is the leading cause of morbidity and mortality throughout the world. We tried to assess the pattern of cardiac disease at coronary care unit (CCU) of tertiary care hospital. Methods: A cross sectional study conducted among the patients admitted at CCU of Dhaka Medical College Hospital (DMCH) during the period of 1st January 2010 to 31st December 2010. A total of 2415 patients were included in the study. Results: A total 2415 patients in the year 2010, were admitted at CCU of DMCH, among them 56% (n=1346) were male and 44% (n=1069) were female. Out of total admitted patients 220 (9%) were below 30 years of age and 588 ( 24%) & 1607 (67 %) were the age group of 31 to 44 years and 45 years and above age group respectively. Among the disease group ischemic heart disease( IHD) (45%) was the most common cause of hospitalization followed by heart failure (HF) (16%) valvular heart disease (9%), hypertension (7%) and arrhythmia (2%). Acute myocardial infarction (30 %) was the leading cause of IHD followed by unstable angina (15%). Conclusion: This study has found that almost three-quarters of cardiac disease were due to IHD, HF and valvular heart disease in decreasing order of frequency. Countries like Bangladesh can be able to spend very little resources to address those cardiovascular diseases. Along with public as well as private sector efforts, public awareness about the risk factors for cardiovascular diseases should be improved to reduce this sort mortality and morbidity.
