Hello! Welcome and thank you for asking on HCM! I read your question carefully and understand your concern. Regarding your concern, I would explain that hemophilia is not relate to heart attacks (which are thrombotic events) but to repeated episodes of hemorrhage. This disorder affects coagulation factors, resulting in an imbalance of coagulation, leading to spontaneous hemorrhages in all the parts fo the body. Some studies have suggested that hemophilia is a protecting factor against coronary artery disease, but many studies have concluded that hemophilic patients have the same cardio vascular risk as other healthy persons. So there is nothing to worry about a heart attack at your age. Your symptoms may be related to anxiety. But I recommend consulting with the GP for a careful physical examination, to exclude other possible complications of hemophilia ( internal hemorrhage or brain hemorrhage). Further tests may need to be performed if suspicions are raised. Hope to have been of help! Best wishes, Dr. Iliri
