Abstract

Diabetes mellitus (DM) and impaired glucose tolerance (IGT) are important cardiovascular risk factors. The objective of this study was to assess the prevalence of DM and IGT in patients discharged from the CCU without known DM after a myocardial infarction. One hundred and ten patients, men and women aged 31-80 years with a myocardial infarction 1-12 months before inclusion were examined with oral glucose tolerance test. Patients with known DM were excluded. A standard oral glucose test (OGTT) with 75 g of glucose was performed. IGT was observed in 29 (26%) patients and DM in 13 (12%) patients in the OGTT. If only fasting plasma glucose (FPG) was used alone five (38.5%) patients with diabetes subjects and three (10.3%) with IGT were identified. Thus, a FPG test alone identified only 19.0% of the patients with pathological OGTT. The prevalence of DM and IGT in patients discharged from the CCU after a myocardial infarction without known DM diagnosis was high (38%). A fasting glucose alone failed to identify more than 80% of the patients with pathological glucose tolerance in this study. Since pathological glucose tolerance is an important cardiovascular risk factor, oral glucose tolerance test should be considered as a routine te...Continue Reading

Cardiovascular Risk Prediction

Cardiovascular risk prediction models based on classical risk factors identified in epidemiological studies are useful in primary prevention of cardiovascular disease in individuals. Here is the latest research.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
