Hi
Thanks for posting your question on HCM.
I appreciate your concern for your father.
Brief reversible
loss of consciousness in an elderly patient with risk factors such as diabetes and
hypertension are highly suggestive of a condition referred to as
Transient ischemic attack (TIA) or impending stroke.
It develops due to reduced blood supply to the brain either due to
atherosclerosis of the main blood vessels (carotids) supply the brain or it can also occur due to a clot (thrombus).
In view of his age and the risk factors, he should be examined by a physician and he needs the following investigations to find out the cause of this ischemic attack like ECG,
Echocardiography, Carotid doppler study, CT scan, fasting blood glucose, clotting profile,etc.
Hope these suggestions could be useful in getting him treated.
Best regards.
