Résumé

Cardiovascular mortality, the principal cause of early death in diabetics, is multifactorial. A prospective study was undertaken to analyse the different factors of excess cardiac complications in 40 patients with type 2 diabetes, whatever the symptomatology, by making an inventory of the cardiac abnormalities (systolic and diastolic left ventricular function, left ventricular hypertrophy, abnormalities of myocardial perfusion, heart rate variability and arrhythmias). Patients underwent 24 hour Holter monitoring, high amplification signal averaged electrocardiography, echocardiography, Thallium scintigraphy with a dipyridamole test followed by coronary angiography when positive. Patients were aged 60 +/- 8 years, diabetics for 11.8 +/- 6.8 years, and had associated cardiovascular risk factors: 85% were obese, 75% were hypertensive, 62.5% had hypercholesterolaemia and 60% were smokers. The HbA1C was 9.2 +/- 19%. An increased left ventricular mass was observed in 34.2% of patients. The left ventricular ejection fraction was normal (59.1 +/- 6.8%); 69.7% of patients had left ventricular diastolic dysfunction. Reduced heart rate variability was observed in 51.8% of cases. Late ventricular potentials were recorded on high amplification signal averaging in 39.5% of patients; 25.6% had significant ventricular extrasystoles and 52.2% had atrial extrasystoles. Twelve patients (45%) underwent Thallium myocardial scintigraphy with a positive dipyridamole test, 8 of whom had coronary lesions on angiography. The excess cardiac complications of diabetes is mainly due to ischaemic heart disease aggravated by autonomic neuropathy, left ventricular diastolic dysfunction, arrhythmias and left ventricular hypertrophy. In future, larger series are required to demonstrate that this detection can guide therapeutic intervention and reduce cardiac morbidity and mortality of diabetics.
