  5. FREQUENCY • CDA isthemostcommontype of heartdisease • Dueto CDA more than 385,000 people die annually • CDA costs North Americans 108.9 billioneachyear • AfricanAmericanshave a higherpercentage (25%) of getting CDA comparedto American Indians’ probability (18%) • In a surveyfrom 2005, only 27% werecoignizant of themajor CDA symptoms • Men are more pronetoget CDA

  6. RISK FACTORS • Age: increasestherisk of narrowedarteries • Cholesterol: itbuilds up atherosclerosis • Familyhistory: if a fatherdevelopedthediseasebeforeage 55 hischildrenhave a higherprobabiity of gettingthedisease • Smoking: Nicotine and carbonmonoxidedamagebloodvessels • HighBloodPressure: thickensthearteries and narrowsthepassageforblood

  7. DIAGNOSIS/TESTS • Electrocardiogram: monitorselectricalsignals and detectsif a heartattack has happened • Echocardiogram: depictsanimage of theheart. It shows ifalltheparts and muscles are normallypumpingblood • CardiacCatheterizationorangiogram: a dyeisinjected in thearteries, and it shows blockagesonthe x-rayimages.

  8. DIAGNOSIS/TESTS • CT Scan: computerizedtomography shows images of theheart. EBCT is a type of CT scan and itdetectshighamount of calcium • MagneticResonanceAngiography: it uses MRI tocheckforareas of blockages • StessTests: measurebloodflowwhentheheartis at rest and during stress

  9. TREATMENTS FOR CAD • Medications-modifyingCholesterol: control of cholesterolpreventsthecreation of plaques • Beta Blockers: decreasetheheart’sneedforoxygenorblood • Calciumchannelblockers: control bloodpressure and relax themusclesaroundthecoronaryarteries • CoronaryArtery Bypass Surgery: A vein is removed from the legs, arms or chest and is connected to the affected artery and to the aorta. • Dailyhabits: Stop smoking, drog and alcohol abuse, exerciseregularly, eathealthy
