iCorMicA - Stratified Medicine in Angina

The iCorMicA study is a multicentre, prospective, randomised, double-blind, sham-controlled, parallel-group, end-point trial and registry. The investigators seek to determine whether stratified medical therapy guided by an adjunctive interventional diagnostic procedure (IDP) during the invasive management of patients with known or suspected angina but no obstructive coronary artery disease improves symptoms, wellbeing, cardiovascular risk and clinical outcomes.

The Anti-Anginal Effects of N-Acetylcysteine (NAC) in Patients with Angina and Non-Obstructive Coronary Arteries (ANOCA)

The goal of this clinical trial is to determine if N-acetylcysteine (NAC) can reduce angina frequency in women with Angina with Non-Obstructive Coronary Arteries (ANOCA). It will also assess the impact of NAC on health status and quality of life. The main questions it aims to answer are: (i) Does NAC reduce the number of angina episodes per week? (ii) How does NAC affect quality of life and symptom burden in ANOCA patients? (iii) Does NAC reduce the need for short-acting nitrate use? Researchers will compare NAC to a placebo in a randomized, double-blind, placebo-controlled crossover study to determine its effectiveness. Participants will receive treatment with NAC 600mg twice daily for 4 weeks (28 days) and matched placebo for 4 weeks (28 days) in a computer-generated random order giving a total dosing period of 8 weeks. There will be a 2-week washout between the two treatment periods. The effectiveness of N-Acetylcysteine (NAC) will be assessed using the following measures: Angina Diary: Participants will record the frequency and severity of their angina episodes. Seattle Angina Questionnaire-7 (SAQ-7): Participants will complete this questionnaire to assess physical limitations, angina frequency, and quality of life. EuroQol 5-Dimension (EQ-5D) Questionnaire: Participants will rate their overall health and quality of life.
