Flashcards in Cardiovascular System Deck (41)
More common in men. More common over 40.
Has high cholesterol content.
LDL (low density lipoprotein)
HDL (high density lipoprotein)
There is insufficient oxygen for the needs of the heart muscle.
Coronary Artery Disease (CAD)
Degeneration in small arteries and arterioles. Loss of elasticity, walls thick and hard, lumen narrows.
Decrease risk for blood clot formation, decrease platelet adhesion, and blocks coagulation process.
Anticoagulant (Heparin, Coumadin, ASA)
Decrease LDL and cholesterol by blocking synthesis in the liver.
Cholesterol or lipid reducing drugs. Lipitor and Zocor.
Chest pain that occurs when there is a deficit of oxygen for the heart muscle.
Coronary artery is obstructed.
Myocardial Infarction (MI). Heart Attack.
Blood clot that goes throughout the body.
ACE Inhibitors treat?
Remove excess water, sodium ions, block reabsorption in kidneys, and treat high BP, CHF.
Decrease BP to normal levels.
Treats angina, hypertension, arrhythmias, prevent SNS from increasing heart activity, SLOWS HEART RATE.
Deviation from normal HR or rhythm.
Cardiac Arrhythmias (Dysrhthmias)
Block movement of calcium ions into cardiac and smooth muscle fibers.
Calcium ion channel blockers (Verapamil)
Provide better balance of xylem supply and demand in heart muscle.
Heart sounds using stethoscope.
Assess general cardiovascular function.
Exercise stress test
Shows size, shape of heart.
Visualization of blood flow in coronary artery.
Passes catheter through a vein in the arm or leg.
PNS - Parasympathetic
Rest and digest system.
Heart rate goes up in this system, fight or flight.
HR 100-160 beats per minute
HR 160-350 beats per minute
HR over 350 beats per minute
Extra contraction of ectopic beats of atria.
Premature Atrial Contraction (PAC)
Heart unable to pump sufficient blood to meet metabolic needs of body.
Congestive Heart Failure (CHF)
