Cardiovascular Disease
A. Palumbo9th Grade HealthSlide2
The Cardiovascular SystemTransports nutrients and removes waste from the body.Supplies blood and oxygen to the body.Slide3
The Cardiovascular SystemHeartArteries VeinsLungs Kidneys Slide4
The HeartSuperior Vena CavaRight and Left atriumRight and left ventricleAortaPulmonary artery Arteries Supply the oxygen to the heart muscleSlide5
Arteries and Veins ArteriesCarry blood away from the heart OxygenatedCarries oxygen all parts of the bodyVeins Carry blood to the heartDeoxygenated Carries carbon dioxide and other wasteSlide6
Lungs and Kidneys Lungs Where the blood picks up oxygen once you inhaleAllows the release of Carbon dioxide once you exhaleKidneysFilters waste out of the bloodSlide7
What is Cardiovascular Disease?Coronary Artery Disease (narrowing the arteries)Heart attacksAbnormal heart rhythms or arrhythmias
Heart failureHeart valve diseaseHeart muscle diseasePericardial diseaseVascular Disease (blood vessels)Slide8
Coronary Artery DiseaseAtherosclerosisHardening of the arteries that provide vital oxygen and nutrients to heartCould eventually cause a part of the heart muscle (myocardium) die off Lack of blood flow. Slide9
Abnormal heart RhythmsSteady heart beats about 60-100 times a minuteHeart can get out of rhythm called arrhythmiaProduce uneven heart beatsCan change rate Cause heart beat to be very slow or very fastSlide10
Heart FailureDoes not mean heart has stopped working Blood is not pumping as well as it shouldLeads to water retention (swelling) and shortness of breath. Slide11
Heart valve and heart muscle A valve lies at each exit of the four chamber of the heartOn wayInsufficiencyCardiomyopathies Disease in heart muscleAlso called enlarged heartAbnormally thick and enlargeCauses weak blood flow Slide12
Pericarditis Inflammation of the lining surrounding the heart Rare condition often caused by infection Slide13
What happens during a heart attack?Myocardial infarctionMyo-muscleCardial-heartInfarction-death of tissue due to lack of blood supplyPlaque builds up in arteries supplying bloodBlood clots form around plaque and totally block the artery This causes part of the muscle to be oxygen deprived and dieCauses permanent damage to heart muscleSlide14
Signs and Symptoms of heart attackShortness of breathChest painsDiscomfort, pressure, heavinessBelow breast boneDiscomfort in arm, back, jaw, or throatSweating, dizzinessNausea, vomiting Extreme weaknessRapid or irregular heart beatsSlide15
Test to diagnose a heart attackECGEKG- can tell how much damage has occurred in heart muscleBlood testLook for Cardiac enzymes to indicate muscle damageCardiac catheterizationCardiac cathCan see direct visual of block arterySlide16
Uncontrollable Risk factors Male SexOlder ageFamily history of heart diseasePost- menopausalSlide17
Controllable risk factorsSmokingHigh cholesterol High LDL “bad cholesterol”HypertensionHigh blood pressurePhysical inactivity Obesity Diabetes (uncontrolled) Uncontrolled Stress and anger Slide18
PreventionDo not smokeControlled diet- EAT RIGHTImprove cholesterol levels Achieve and maintain healthy weight Regular exercise- BE ACTIVE30-60 minutes most days of the weekControl Hypertension Exercise and good dietManage StressSlide19
Statistics Cardiovascular disease is the leading cause of death in both men and women in the US. Heart failure is a major health problem in US affecting 5 million Americans.
The leading cause of hospitalization in people over 65Slide20
Statistics Cont.About eight out of 1,000 children are affected by congenital heart disease.Coronary artery disease cause abut 1.2 million heart attacks each year. About 40 percent will dieSlide21
