I have CAD (Coronary Artery Disease) 3 stents in the heart, waiting for a 4th and one in my Thoracic Aorta due to a Aorta Dissection. RA is not the only cause for me of course, CAD can be hereditary which mine is. The RA and Psa inflammation on contributes of course. Diet, exercise when possible and meds, that is the treatment here. Keep regular appointments with Cardiologist, Vascular Surgeon and tested at least once a year via different types of MRI / scans, blood work and more. I feel lucky I am still alive with not heart damage at this time. I wish you much luck with your coronary and RA issues.
