[Clinical characteristics of angina pectoris in relation to disease of the coronary arteries].
Clinical and coronary angiographic comparison conducted in 164 patients with typical angina pectoris demonstrated that the nature of the pains may serve as a criterion of the degree of stenosis and the number of diseased arteries. The development of typical anginal seizures indicates the presence of clear changes in the coronary arteries. A daily intake of over 10 pills of nitroglycerine is a sign of a narrowing of the diameter of the coronary arteries exceeding 75%. A growing number of daily taken pills of nitroglycerine indicates an increase in number of diseased coronaries. Pains occurring during or after meals, when lying down, awakening the patient at night are typical for coronary narrowings exceeding 75% of their diameter. Usually such pains are observed in patients with 2 and more cornary arteries affected by the disease. Rightward irradiation and especially strictly localized pains are often associated with the lesion of the right coronary artery.
