Hello. Thank you for asking on HCM. I carefully read your query and will try yo be thorough with my answer. The above described symptoms could be of various origins. As a cardiologist, I would like to clear the cardiac origin first. Chest pain with coronary artery origin is called angina and it is described as a chest tightness, heaviness which starts in the midchest region, radiates to both sides of the chest, throat, jaw and left arm, start with physical activity and ceases with the cessation of this physical activity. People with high blood pressure are prone to have these symptoms and, adding your age, are in risk for cardiovascular events. I would recommend you to be put on a 24-hour blood pressure monitor to see if your hypertension is properly controlled, and further adjustment should be made. As for the episodes with losing memory and not remembering what where you doing, I am not sure if these are fainting episodes. Anyway, I would recommend a 24-hour Holter rhythm monitor and a colour Doppler echo of the carotid (neck) arteries. Then, it would also be advisable you consult with a neurologist. At the end, I would also recommend some blood tests: cholesterol, LDL-fraction, triglycerides, urea, creatinine, liver function tests and fasting and 2 hours after the meal glucose. It is after this body of exams are done, when we can further discuss for further properly treating the main and side problems. Feel free to ask again. I hope I was helpful. Take care.
