Disfunción ventricular izquierda subclínica en diabéticos tipo I con 10 o más años de evolución de la diabetes Subclinical left ventricular dysfunction in type 1 diabetics with 10 or more years of diabetes progression. Rev Cubana Endocrinol [online]. 2001, vol.12, n.2. ISSN 1561-2953.

A cross-sectional study of 32 type 1 diabetics aged 17-40 years, with 10 or more years of diabetes profession was conducted to find out the frequency of subclinical left ventricular dysfunction (LVD) and its associated factors. Those patients presenting with valvulopathy, ischemic heart disease, blood hypertension and other diseases leading to myocardiopathy, were excluded. Their complete medical histories were made and they were indicated the following: glycemia in fasting conditions, glycosylated hemoglobin, total cholesterol, total triglycerides, high density lipoprotein, urine excretion of albumin, speed of motor and sensitive nerve conduction in lower limbs, electrocardiogram and pulsed Doppler bidimensional M mode echocardiography. For the echocardiographic diagnosis of left ventricular dysfunction, the criteria submitted by the American Society of Echocardiography were adopted. LVD was confirmed in 34.3 % of patients. Structural cardiac abnormalities were observed in 18.75% of cases; peripheral neuropathy was found in 8 of 11 patients with LVD (72.7%); the levels of urine excretion of albumin were significantly higher in those affected by LVD(233.4±176 mg/L).The thickening of the interventricular septum and the posterior wall was markedly greater in patients with LVD. It was concluded that LVD is a frequent complication in type 1 diabetics, which makes it necessary to systematically look for this disorder in this group of patients
