Electrocardiographic Changes in Patients with Type 2 Diabetes Multicenttic Cross Sectional and Descriptive Study in Dakar

摘要

Introduction: The resting electrocardiogram is generally called upon in the evaluation of cardiovascular risk in diabetics. Thus we proposed in this work to evaluate electrocardiographic changes in patients with type 2 diabetes. Methods: This was a cross-sectional and descriptive observation that took place from 1 January 2014 to 1 October 2014 in the Internal Medicine/Endocrinology Departments of Pikine National Hospital and Cardiology National Hospital of Grand-Yoff. Results: One hundred (100) patients consisted of 43 male and 57 female diabetics. The sex ration male/female ratio was 0.7. The average age was 58.3 years. Men were twice as likely to be active as women. Rhythm disorders were noted in 20% of patients, 13% of whom were women. Right atrial hypertrophy was found in 11% of patients and left hypertrophy in both men and women (25%). Wolf-Parkinson White syndrome was present in 2% of patients. A complete right bundle block was present in 11% of patients. Primary repolarization disorders were noted in 17% of patients and secondary in 18% of patients, postero-diaphragmatic necrosis in 14% of patients, real posterior necrosis in 2% of patients, extensive anterior necrosis in 15% of patients. The QT interval was lengthened in 21% of patients including 14 women. Left ventricular hypertrophy was present in 33% of patients and right ventricular hypertrophy was found in 10% of patients. The bivariate analysis showed that electrocardiographic abnormalities were more correlated with the association of certain risk factors such as hypertension and dyslipidemia, the feminine gender, but also the poor glycemic balance. On the other hand, physical activity and treatment had a protective effect. Conclusion: The ECG is certainly insufficient for an exhaustive exploration of the heart of the diabetic patient, but still very useful in our conditions of exercise to improve the care of our patients.
