No wonder I'm short of breath

My stress test results came today: coronary artery disease. I need to see a cardiologist for a full explanation but evidently I have "1 vessel disease" and on the report the cardiologist who read my scan stated "moderate severity inferior completely reversible defect consistent with ischemia" Well - completely reversible sounds good to me. Guess that's why I've been having pain in my left ribcage....must not have been the ribs, but the heart underneath them. I am so glad to finally be getting some answers!
