hi I wud like to share some useful knowledge abt heart attack & bypass surgery Heart attack is the condition due to lack of oxygen to heart muscles which becomes dead.This lack occuars due to blockage in coronary arteries which is due to deposiiton of plaques formed of cholestrol & platlets mostly & cut down the blood supply to heart muscles. The block may be in single vessel or multiple like two or three . Now a days in acute heart attack treatment is immediate angioplasty or dissolving of clot by medication ( in injection for ) Angioplasty is the term used when the blocked arteries are open up by putting a catheter ( hollow tube ) through leg artey guided in blocked artery by direct visulization on Tv screen & then by very small microscopic rotter blades cutting of block & clearing the blocked artery within few hours of attack & thus preventing the heart muscle to get damaged permanently. This is followed by medical treatment. But this is like clearing the choked pipe we do in kitchen but to keep it patent w have to stop things which wud block it again. This is by changing life style - reducing anxiety & stress. Change in food habits eating lots of fresh fruits & saalds ,high fiber diet & stopping smoking ,excessive consumption of alcohal . Daily walking briskly for atleat 45 mts. control of blood sugar & cholestrol levels . Reducing wt if overwt or obese. Daily yoga definately helps in prevention of reurrence of problam. coronary bypass surgery - is open heart surgery now a days done on beating heart without help of heart lung bypass machine . In this the blocked artery is removed & grafted with artery taken from hand or leg veins preferabbly artey & not veins as veins get reblocked earlier ) This mat be done if two or multiple blocks are present at multople level &angioplasty is not pssible ( angioplasty is done on single or two vessels ) After coronary bypass similar life style modifictions r necessary & one can lead a very normal life. Generally these surgeries are very safe in good centre in expert hands.
