[Factors influencing the prognosis in patients with angina pectoris. Significance of dynamic coronary occlusion]. / Faktory, vliiaiushchie na prognoz bol'nykh co stenokardiei. Znachenie dinamicheskoi koronarnoi obstruktsii.

Using the results of a prospective follow-up of 106 patients with angina, the authors examined the factors influencing the prognosis of coronary heart disease, including the prognostic value of dynamic coronary occlusion detected during an intravenous ergometrine test. The indicators that are most typical of patients groups with varying outcomes were identified by using the discriminant analysis. The highest value is shown by the factors associated with the extent of coronary occlusion in the prediction of a fatal outcome. A tendency to vasoconstrictive reactions shown as a high sensitivity to ergometrine is a risk factor of myocardial infarction and acute heart failure in individuals highly tolerant to exercise.
