Cardiac function was studied in 30 patients with insulin-dependent diabetes mellitus. Three groups, matched for age and diabetes duration, were defined as: group I (n = 10), normal urinary albumin excretion less than 30 mg 24 h-1; group II (n = 10), incipient diabetic nephropathy (urinary albumin excretion in the range of 30-300 mg 24 h-1); and group III (n = 10), clinical diabetic nephropathy (urinary albumin excretion greater than 300 mg 24 h-1). Ten non-diabetic subjects matched for sex and age served as controls. The left-ventricular end-diastolic volume measured by radionuclide cardiography was, at rest and during exercise, lower in group II and III compared with controls (p less than 0.05), while intermediate values were found in group I. The cardiac output was similar in the control group and group I; it was reduced, but not significantly so (p = 0.10), in group III and was significantly lower in group II (p less than 0.05). Stroke volume was also lower in group II and III than in controls (p less than 0.05), but not so in group I. These differences could not be explained by differences in metabolic control, blood pressure, blood volume status, degree of autonomic neuropathy or frequency of coronary heart disease. Our results might suggest that insulin-dependent diabetic patients with slightly but persistently elevated urinary albumin excretion have reduced diastolic compliance of the left-ventricle leading to impaired cardiac performance.(ABSTRACT TRUNCATED AT 250 WORDS)
