Reabilitação cardíaca em doentes coronários com diabetes mellitus tipo 2: Estudo comparativo

Abstract

Introduction and AimsDiabetic patients have a 2‐4 times higher risk of cardiovascular disease than non‐diabetic individuals. The aims of this study are to evaluate the effects of a cardiac rehabilitation program (phase II) in patients with diabetes and coronary disease and to compare the results with regard to control of cardiovascular risk factors and improvement in functional capacity with coronary patients without diabetes. MethodsThis was a prospective study of patients diagnosed with ischemic heart disease referred for a cardiac rehabilitation program between January 2009 and June 2013. The population was divided into two groups: diabetic and non‐diabetic. Patients were assessed at the beginning of phase II and three months later and the following parameters were recorded: body mass index, waist circumference, lipid profile, blood glucose and glycated hemoglobin in diabetic patients, blood pressure, smoking, physical activity level (using the International Physical Activity Questionnaire) and functional capacity (on treadmill stress testing). ResultsThe study population consisted of 682 patients (253 diabetic and 429 non‐diabetic). Diabetic patients were significantly older, had a worse cardiovascular risk profile (higher prevalence of overweight, dyslipidemia, hypertension and sedentary lifestyle) and lower functional capacity. At the end of phase II, there was a statistically significant improvement (p<0.05) in all risk factors and functional capacity, which was similar in both groups, except for body mass index, triglycerides and functional capacity. ConclusionsDiabetic patients may benefit from a cardiac rehabilitation program and achieve comparable results to non‐diabetic patients.
