Hello! Thank you for asking on HCM! I read yuor question and understand your concern. I would like to explain that foot pain is not a symptom of heart attack and neither a cause of it. I would recommend you to consult with your GP and perform some tests to establish the cause of this pain and find the proper therapy : - routine blood test - inflammation tests, PCR, fibrinogen, sedimentation -blood electrolytes, blood calcium levels, uric acid levels -foot x ray - Doppler ultrasound of the vessels of the legs -nerve conduction study for the nerves of the leg Hope to have been helpful! Greeting! Dr. Iliri
