  • Heart Failure

    Decreased cardiac output

  • Ejection Fraction

    Percentage of blood in heart that is ejected with systole

  • Heart failure PERSERVED ejection fraction (HFpEF)

    EF ≥50%

  • Heart Failure REDUCED ejection fraction (HFrEF)

    EF less than 40%

  • 3 features of fetal circulation

    1. Ductus venosus 2.Foramen ovale 3. Ductus arteriosus

  • Hypoxia

    Lack of oxygen

  • Ischemia

    Lack of blood flow

  • Pulse pressure

    Difference between systolic and diastolic BP

  • Prinzmetal (variant) angina

    Coronary arteries seize during REM sleep

  • Atherosclerosis

    Plaque build up in arteries (subtype of arteriosclerosis), inflammatory disease

  • Arteriosclerosis

    Thickening or hardening of the arteries

  • Laminar Blood Flow

    Uninterrupted, parallel blood flow

  • Eisenmenger syndrome

    Blood flow changes result in deoxygenated blood entering systemic circulation. Symptoms- cyanosis, polycythemia and clubbed fingers

  • Stored cellular energy

    adenosine triphosphate (ATP)

  • Shock

    State of very low BP and flow resulting in syncope, inadequate organ perfusion, and possibly death

  • Types of distributive shock (vasodilation)

    1. anaphylaxis 2. septic 3. neurogenic

  • Vascular changes in older adults

    1. Endothelial dysfunction- inflammaging 2. Systolic HTN- vascular stiffness (arteriosclerosis), production of vasoconstrictors> vasodilators 3. More aneurysms (elastin replaces collagen) 4. More vein disorders

  • Venous Ulcers

    Open sore caused by tissue breakdown d/t fluid accumulation secondary to poor venous return
