Hello! Thank you for asking on HCM ! I understand your concern, and would like to explain that your clinical scenario is more compatible with your spondilities problem. If you haven t cardiac ischemic symptomatology, and no any abnormal changes on your vital parameters (BP, heart rate, no dyspnea, etc) or any other clinical signs at all, there is not any reasons to worry for the moment. Nevertheless, I recommend you to perform a medical check up, for a careful physical exam, resting ECG, and some blood tests (complete blood count, complete urine test, liver and renal function tests, blood electrolytes, a cervical X ray, etc). Regarding your next RCA angioplasty it depend on your coronary lesions anatomy; on ho severe is the remaining coronary stenosis, and on the intensity of clinical signs it may probably produce. A review of your coronary angiography report, and a cardiac stress test would be necessary to decide the right time to intervene. Hope to have been helpful to you! Greetings! Dr. Iliri
