Angina Pectoris, Variant Clinical Trial
Official title:
Stepwise Treatment and Acetylcholine Rechallenge in Vasospastic Angina to Guide Patient-tailored Treatment
The goal of this clinical trial is to assess the feasibility and clinical value of acetylcholine (ACH) rechallenge after intracoronary verapamil +- nitroglycerine in a patient cohort with angina and non-obstructive coronary arteries (ANOCA). The main questions it aims to answer are: - to determine the efficacy of these drugs in treating ACH-induced coronary artery spasm - to determine the efficacy of these drugs in preventing ACH-induced coronary artery spasm The ACH rechallenge will take place during the index coronary function tests in patients with proven ACH-induced vasospastic angina. The study is considered a feasibility study, no control arm is included.
