Cardiovascular System Flashcards
More common in men. More common over 40.
Atherosclerosis
Has high cholesterol content.
LDL (low density lipoprotein)
Good 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.
Arteriosclerosis
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.
Angina Pectoralis
Coronary artery is obstructed.
Myocardial Infarction (MI). Heart Attack.
Blood clot that goes throughout the body.
Embolus
ACE Inhibitors treat?
Hypertension, CHF
Remove excess water, sodium ions, block reabsorption in kidneys, and treat high BP, CHF.
Diuretics
Decrease BP to normal levels.
Antihypertensive drugs
Treats angina, hypertension, arrhythmias, prevent SNS from increasing heart activity, SLOWS HEART RATE.
Beta-blockers
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.
Vasodilators (Nitroglycerin)
Heart sounds using stethoscope.
Auscultation
Assess general cardiovascular function.
Exercise stress test
Shows size, shape of heart.
Chest X-Ray
Visualization of blood flow in coronary artery.
Angiography
Passes catheter through a vein in the arm or leg.
Cardiac Catheterization
PNS - Parasympathetic
Rest and digest system.
CNS- Sympathetic
Heart rate goes up in this system, fight or flight.
