Hello! Thank you for asking on HCM! Regarding your concern, I would explain that your systolic blood pressure values are really low. I would recommend consulting with your attending physician and performing further tests to investigate for the possible cause of low blood pressure and low pulse pressure: - a cardiac ultrasound and resting ECG to examine your heart function and structure and exclude possible heart failure which could lead to this symptomatology - a chest X ray study - some blood lab tests (complete blood count for anemia, thyroid hormone levels, cortisol and aldosterone plasma levels, blood electrolytes, kidney and liver function tests). Meanwhile, I recommend taking plenty of fluids to remain well hydrated and increase the amount of salt that you take in your diet. Caffeine would also be useful. I would also advise you to avoid straining physical activity and staying in hot places. Hope you will find this answer helpful! Best wishes, Dr. Iliri
