| Popis: | To evaluate the relationship between angina pectoris caused by dynamic exercise and the time course of heart rate (HR) and hemodynamics during dynamic exercise in 15 patients with hypertrophic cardiomyopathy (HCM) with normal epicardial coronary arteries, the supine ergometer exercise test was performed during cardiac catheterization. The HCM patients were divided into a chest pain group (n = 6) and a no chest pain group (n = 9) based upon the results of the ergometer exercise test. There was no significant difference in the level of ST-segment depression after exercise in both the chest pain and no chest pain groups (-2.1 +/- 0.6 mm vs -2.6 +/- 1.1 mm, NS). Increase in heart rate (HR) and left ventricular end-diastolic pressure (LVEDP) in the early phase of the exercise test was significantly greater in the chest pain group compared with the no chest pain group. These observations suggest that in HCM patients, the occurrence of exertional chest pain has a close relationship with the rapid increase in HR and LVEDP in the early phase of dynamic exercise, but does not have a relationship with the gradual increase in these parameters. |
