Is it possible to cure artery blockage by pranayam?

Hello Vishal, Bypass surgery (CABG) is the choice of treatment in case of your father. Kindly consult a cardiologist who on complete evaluation of the patient will suggest you the entire line of treatment. Yoga is good to keep a person fit but there is no documentation of pranayam curing major heart blockage. It is advised to consult a cardiologist and take a wise decision. Hope my answer helps you.
