Combined Monitoring (ECG-MT and CGMS) in the Study of Arrhythmogenic Factors in Patients with Diabetes Mellitus Type 2 Suffering from Chronic Cardiac Failure
The aim of the work is to study the structure of cardiac rhythm disturbances and the possibilities of combined ECG-monitoring and glycemia monitoring to reveal arrythmogenic factors in patients with chronic cardiac failure (CCF) suffering from diabetes mellitus type 2 (DM2).
Materials and Methods. 80 patients with DM2 suffering from CCF of ischemic genesis have been examined. All the patients have undergone physical examination, blood test for cholesterol and creatinine), urinalysis for proteinuria and microalbuminuria. To reveal the severity of heart failure, there have been used a 6-minutes’ walking test and clinical condition scale according to V.Y. Mareev. Echocardiography and daily ECG-monitoring have been carried out. Carbohydrate metabolism has been examined, and in 20 patients a continuous blood glucose monitoring within 3 days has been performed.
Results. Supraventricular extrasystole and paroxysms of unstable supraventricular tachycardia (51%), atrial fibrillation (42,5%) appear to be the most frequent. The disturbances of ventricular rate of high gradations are revealed in 26% of patients. Chronic hyperglycemia is associated with atrial fibrillation. Hypoglycemic conditions among diabetic arrhythmogenic factors of ventricular rate disturbances are foremost.
Conclusion. Optimal glycemia management can be considered as a method of prevention of cardiac rhythm disturbances in patients with chronic cardiac failure suffering from DM2.
