Hello! Thank you for asking on HCM! Regarding your concern i would recommend her to consult immediately the nearest doctor because when talking about chest pain and shortness of breathing it is very important to pass through a fast and comprehensive differential diagnosis, in order to rule out first the major and life-threatening chest pain syndromes (heart attack, pulmonary embolism, aortic dissection) passing to panic attacks to the end. And this is done the best way by immediate careful physical examination, coupled with resting ECG, eventual cardiac ultrasound, and some lab tests (including cardiac enzymes). Additional imagine chest studies like chest X ray or CT,etc. may be needed. So my only advice is to recommend your friend to visit the doctor immediately. Hope to have been helpful to you. Greetings! Dr. Iliri
