ABSTRACT
Stress electrocardiography and echocardiography using atrial pacing together with the right-sided heart catheterization were performed in 21 patients with stable angina pectoris. Peak velocity of transmitral flow in early diastole (E) and in atrial contraction (A), deceleration time of early filling, and pulmonary artery wedge pressure were measured simultaneously at rest and immediately after each pacing frequency. Patients were divided according to their stress pulmonary artery wedge pressure changes into Group A (14 patients with an increase in pulmonary artery wedge pressure > or = 3 mmHg during stress) and into Group B (6 patients with a change in pulmonary artery wedge pressure < or = 2 mmHg during stress). One patient, T.L., with an increase in pulmonary artery wedge pressure > or = 5 mmHg after each pacing frequency was evaluated separately. In Group A patients, the non-linear course of the E/A ratio changes (from 0.78 +/- 0.06 to 0.66 +/- 0.05, P < 0.01; to 0.72 +/- 0.05, P = NS; and to 0.93 +/- 0.06, P < 0.01) and deceleration time changes (from 188.9 +/- 7.2 ms to 195.3 +/- 8.9 ms, P = NS; to 188.8 +/- 9.9 ms, P = NS; and to 154.2 +/- 6.7 ms, P < 0.01) was seen.(ABSTRACT TRUNCATED AT 250 WORDS)
