Abstract

The Studies of Left Ventricular Dysfunction (SOLVD) comprises 2 double-blind, randomized clinical trials to test improved survival by angiotensin-converting enzyme inhibitor in patients with left ventricular dysfunction, with or without congestive heart failure. Patients entering the trials may be a highly selected subset of the population of such patients; those with the worst and best prognosis are likely to be excluded. To obtain the clinical history of a broader group, a registry of 6,273 patients included a relatively unselected cohort of patients with heart failure or left ventricular dysfunction, or both, from SOLVD hospitals. Registry data were obtained from hospital records. Because data collection from medical records may lead to incomplete data and more investigations in "sicker" patients, 898 randomly chosen subjects from different disease strata were seen in clinic where neurohumoral measures, echocardiograms, x-rays and electrocardiograms were obtained, and a 6-minute walking test was performed. The design and methodologic features, and the baseline characteristics of the participants in this 2-tiered registry are described, and its use in complementing the results and interpretation of the SOLVD trials is discussed.
