[Clinical characteristics and diagnosis of stenocardia in persons with normal coronary vessels].

To date, the clinical pattern and electrocardiographic diagnosis of only one variant of coronary heart disease (CHD) with unchanged coronarogram, Prinzmetal's angina, have been worked out, while the diagnosis of other variants remains undeveloped. Clinical symptoms and possibilities of CHD diagnosis in the presence of intact coronary arteries have been evaluated in 67 coronary patients, the coronarograms being normal in 46 of those. The diagnosis of CHD was verified by means of various instrumental methods, including electrocardiographic tests and myocardial metabolic studies in conditions of frequent atrial stimulations.

The questionnaire comprises five sections, each corresponding to a certain type of pain. A diagnostic statement is made after each section.
