Prevalencia de cardiopatía isquémica asintomática en pacientes con diabetes mellitus tipo 2

Abstract

IntroductionCardiovascular disease is the main cause of death in patients with diabetes mellitus. The prevalence of asymptomatic ischaemic heart disease is higher in diabetic patients than in non-diabetic ones, and is associated with a worse prognosis. ObjectiveTo determine the prevalence of asymptomatic ischaemic heart disease in patients with type 2 diabetes mellitus in a third level of care hospital in Guatemala, as well as to analyse the possible relationship of this disease with epidemiological, clinical, and metabolic characteristics. MethodsA cross-sectional study was conducted on a sample of 92 randomly selected diabetic patients. An electrocardiogram was performed, which when it was negative for ischaemia, an exercise stress test or a dobutamine stress echocardiogram was performed. ResultsThe mean age of the participants was 57 years, 88% of whom were women. The mean duration of the diabetes was 7 years. Asymptomatic ischaemic heart disease was found in 22.8% of case. No significant associations were found between ischaemic heart disease and age, gender, peripheral arterial disease, body mass index, ankle-brachial index, arterial hypertension, dyslipidaemia, active smoking, sedentarism, overweight/obesity, alcoholism, fasting glucose, glycosylated haemoglobin, total cholesterol, HDL-cholesterol, LDL-cholesterol, uric acid, creatinine, glomerular filtration rate, and urine microalbumin. ConclusionsThe prevalence of asymptomatic ischaemic heart disease was 22.8% in the population studied with type 2 diabetes mellitus. No significant associations were found between ischaemic heart disease and the variables studied.
