[The risk assessment for a fatal outcome in patients with stable angina based on the data from a long-term prospective observation (a comparison of the 5-year survival prognosis with the data at the 6th to 12th years of the observation)].
A rule has been developed to predict coronary death in 377 patients with coronary heart disease and stable angina due to coronary stenotic atherosclerosis. Gravimetric values of various clinical signs, resting ECG changes, and bicycle ergometric testing have been obtained by a computer. A decisive rule has been also derived. According to the values of prognostic indices I1 and I2, groups of low, moderate, and high risks for fatal outcomes for 5 years have been identified and the patient's survival during a subsequent follow-up of 6 to 12 years has been assessed. The developed scheme of prognosis permits its use in practice.
