New-onset angina pectoris: initial characteristics and results of a 6 to 12-month follow-up.

173 patients, aged 46.8 years on the average, were examined in the first 3 months after onset of angina pectoris. 97% of them presented at least one of risk factors (smoking, arterial hypertension, overweight, dyslipoproteinaemia), in 79% two or more risk factors were present simultaneously.

24-hour ECG monitoring was performed in 12 patients with primary vasospastic angina (PVA). Angiography revealed a predominant lesion to a single coronary vessel (83%). There were 64 episodes of ST-segment changes (46 elevations and 18 depressions) during the monitoring that lasted 388 hours and 54 minutes.

A total of 130 patients with angina of new onset were examined within first 3 months of the disease. Macrofocal myocardial infarction survivors were not admitted to the study. The investigation included selective coronaro-angiography and ventriculography, Holter's ECG monitoring over 24 to 48 hours and bicycle ergometry.

The diagnostic value of exercise tests and Holter's ECG monitoring was assessed in 111 patients within the first 3 months since the onset of anginal attacks; 22 of those had a history of large-focal myocardial infarction. Coronaro-angiography was performed in all cases, and its results were compared with those of exercise tests in 107 patients, and of Holter's ECG monitoring, in 104. Bicycle ergometry was positive in 48% of patients.
