[Features of individual pain sensitivity of patients with ischemic heart disease during different variants of bicycle ergometry test].

Aim: To assess the significance of individual pain sensitivity in the development of painful and painless episodes of acute myocardial ischemia.

Materials And Methods: Bicycle ergometry test was carried out in 50 patients aged 35-65 years with angina of effort, functional classes II-III. Before bicycle ergometry, tactile and pain sensitivity thresholds and duration of pain tolerance were assessed by SSM-01 sensometer.

Results: Twenty-seven patients showed painful reaction to exercise; 40% of them had a low threshold of pain and 81% poorly tolerated pain. In 11 patients who complained of pain before ECG showed myocardial ischemia, these values were 64 and 91%, respectively. All of 9 patients with painless myocardial ischemia had a high threshold of pain, and 44% of them poorly tolerated pain.

Conclusion: The data indicate significance of individual pain sensitivity in the development of painless episodes of acute myocardial ischemia.
