Atherosclerosis › Hardening of the arteries that provide vital oxygen and nutrients to heart Could eventually cause a part of the heart muscle (myocardium) die off › Lack of blood flow.
Steady heart beats about 60-100 times a minute Heart can get out of rhythm called arrhythmia Produce uneven heart beats Can change rate › Cause heart beat to be very slow or very fast
Does not mean heart has stopped working Blood is not pumping as well as it should › Leads to water retention (swelling) and shortness of breath.
A valve lies at each exit of the four chamber of the heart › On way › Insufficiency Cardiomyopathies › Disease in heart muscle › Also called enlarged heart › Abnormally thick and enlarge Causes weak blood flow
Inflammation of the lining surrounding the heart Rare condition often caused by infection
Myocardial infarction › Myo-muscle › Cardial-heart › Infarction-death of tissue due to lack of blood supply Plaque builds up in arteries supplying blood Blood clots form around plaque and totally block the artery This causes part of the muscle to be oxygen deprived and die Causes permanent damage to heart muscle
Shortness of breath Chest pains › Discomfort, pressure, heaviness › Below breast bone Discomfort in arm, back, jaw, or throat Sweating, dizziness Nausea, vomiting Extreme weakness Rapid or irregular heart beats
ECG › EKG- can tell how much damage has occurred in heart muscle Blood test › Look for Cardiac enzymes to indicate muscle damage Cardiac catheterization › Cardiac cath Can see direct visual of block artery
Male Sex Older age Family history of heart disease Post- menopausal
Smoking High cholesterol › High LDL “bad cholesterol” Hypertension › High blood pressure Physical inactivity Obesity Diabetes (uncontrolled) Uncontrolled Stress and anger
Do not smoke Controlled diet- EAT RIGHT › Improve cholesterol levels › Achieve and maintain healthy weight Regular exercise- BE ACTIVE › 30-60 minutes most days of the week Control Hypertension › Exercise and good diet Manage Stress
