Hello,

It is necessary to know his LVEF(left ventricualr ejection fraction) after by-pass surgery by 2-D Echocardiography. Low BP may be due to low LVEF.

Also, it is necessary to know his serum electrolytes particular serum sodium level as elderly people often suffer from chronic hyponatremia. and correction of sodium level may restore normal BP.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
Dr Tushar Kanti Biswas, Internal Medicine Specialist
