Hello!
Welcome and thank you for asking on HCM!
I passed carefully through your history and would explain that his blood pressure values are not too low to cause
fainting or
dizziness.
Orthostatic hypotension could be the cause of his symptomatology.
I recommend measuring his blood pressure during sitting and standing up position. If there is a decrease in his blood pressure more than 20mmHg during standing up position, compared to sitting position, this could indicate orthostatic hypotension.
A Head up Tilt test is needed to rule in/out this disorder.
I would also recommend performing some other tests to exclude other possible causes related to his heart:
- a resting ECG and cardiac ultrasound
- some blood lab tests (
complete blood count, kidney and liver function tests, blood electrolytes, fasting
glucose and HbA1C).
If orthostatic hypotension is confirmed some modifications to his actual therapy may be needed.
Hope you will find this answer helpful!
Greetings!
Dr. Iliri
