[Does routine angiographic control make sense after percutaneous coronary intervention?].

Background And Purpose: Is it possible to avoid routine coronary angiography after previous coronary intervention, if angiography is done only on patients with pathologic or questionable results in noninvasive diagnostic tests (recent medical history, exercise electrocardiography)?

Patients And Methods: During the period from January 1996 until December 2000, all patients who underwent interventional treatment of coronary vessels (n = 509) were routinely reexamined by coronary angiography within 3-6 months. Out of the total group as well as out of the patients with normal exercise electrocardiography, all patients with significant restenosis or new stenosis were identified. Patients with pathologic exercise electrocardiography and patients who could not tolerate exercise electrocardiography were marked.
