Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that in your clinical situation, it is important excluding possible secondary causes of high blood pressure. For this reason, I would recommend consulting with your attending physician for a careful physical exam and some lab tests: - a resting ECG - a chest Xray study - blood work (complete blood count, thyroid hormone levels, blood electrolytes, kidney and liver function tests, fasting glucose). I would also recommend performing a fibrogastroscopy as the pain in the middle of the chest after eating could also be related to hiatal hernia or fibrogastro-esophageal reflux. Hope to have been helpful! Kind regards, Dr. Iliri
