Introduction
Theword “heart attack”with reference to any person having suffered it,makes one sit up.Heartattackoccursdue toblockageornarrowingof thearteries, that supplyblood to theheartmuscles.Every person thinks it cannot affect him. It can only occur to the person next door. A famouscardiologistoncesaid that ifanymansuffers froma“heartattack”before theageof80years,hislifestylehas tobeblamed.Man should survive till 100years ifhedoesnot abusehisphysical andmentalhealth.

Like other parts of the body, the heart receives its food (oxygen and nutrients, e.g. glucose)throughasystemofarteries,knownascoronaries.Thechancesofasmokersufferingfromaheartattackare three timesmoreascomparedtoanon-smoker.Onquitting,theriskiscuttohalfinaboutayear ’stime.After10yearsyouroddsnearlyreturntonormal.
CoronaryArteries

PlaqueFormation
Plaque is a fatty substance in the blood (like cholesterol)which often builds up in and around thesmootharterialmuscles.Clotformingplateletscanaccumulateonthis.Duetotheformationof theplaque,blockageofthevesselsstarts,restrictingthebloodflow.
