title: [Characteristics of the clinical manifestations of stenocardia in patients with ischemic heart disease, without myocardial infarct, in relation to the state of the coronary bed].
abstract: Mono- and multifactorial discriminant analyses aided by computer were used in 106 patients with coronary disease to compare the clinical and angiographic findings common to different manifestations of angina pectoris. The relationship was discovered between the clinical form of angina pectoris and the gravity of lesions of the coronary artery. Intracardiac hemodynamics and left ventricular contractility at rest did not differ whatever the patients' group. According to the bicycle ergometry test, the physical exercise tolerance was lower in patients with progressive angina pectoris and depended on the gravity of coronary artery lesions. The outcome of the clinical manifestations of angina pectoris during observation at hospital was mainly influenced by the natural course of coronary disease, primarily stipulated by obstruction in the coronary arteries. Using the multifactorial discriminant analysis aided by computer, the classifying signs were outlined, making it possible to differentiate between the groups of angina pectoris patients depending on the duration of angina pectoris attacks (in minutes), irradiation of pain to the shoulder or to both arms, T wave inversion on the ECG, and the gravity of coronary artery obstruction. The given signs enable one to recognize patients with destabilization of the clinical course of angina pectoris.
