Chest Pain Clinical Trial
Official title:
Randomised Controlled Trial of Vericiguat in Patients With Coronary Microvascular Dysfunction Causing Stable Chest Pain (V-COM)
This is a randomised controlled trial to determine the effectiveness of Vericiguat to improve stress myocardial blood flow (MBF) and myocardial perfusion reserve as measured by cardiac magnetic resonance (CMR) imaging.
Stable chest pain is one of the most common complaints by patients. However, about 50% of patients referred for catheter coronary angiograms do not have obstructive coronary artery disease (CAD). In the United Kingdom (UK), one very large population study showed that ~70% of patients did not have a cause for the chest pain diagnosed within 6 months of presentation. Furthermore, the study further showed that this group of patients had a significantly higher risk of major adverse cardiovascular events (MACE) compared to patients without chest pain. It is now understood that the two major causes of cardiac chest pain with non obstructive CAD (also known as Ischaemia with Non Obstructive Coronary Arteries (INOCA)) are coronary microvascular dysfunction (CMD) and the other is coronary vasospasm. CMD and coronary vasospasm have been shown in one randomised controlled study to comprise 52% and 17% of all patients with INOCA. However, therapies for CMD are lacking and has been highlighted as a major area of need. ;
