    Study Notes

    Pathogen 4.1 Vessels

    • Vessels are categorized by their function and morphology
    • Objectives of this section include illustrating fluid distribution, distinguishing causes of edema, analyzing the role of renal pathology in fluid balance, and analyzing hemorrhage.
    • The role of endothelial cells, platelets, and the coagulation proteins in hemostasis is analyzed.
    • Pathogenesis of thrombus, embolus, hypercoagulability, infarction, and shock will be examined.
    • Different forms of aneurysm, arteriosclerosis, and vascular disease will be discussed.
    • The major phenotypic features, inheritance, etiology, incidence, pathogenesis, and clinical course of familial hypercholesterolemia will be dissected.
    • Essential and secondary hypertension and related pathogenesis will be distinguished.
    • Types of aortic dissection and their consequences are investigated.
    • Pathogenesis of vasculitis and vascular tumors is discussed.

    Fluid Balance

    • Fluid balance is governed by two opposing forces: hydrostatic pressure and oncotic pressure.
    • Hydrostatic pressure "wins" but only a little bit.
    • Lymphatics manage the extra fluid.
    • Causes of edema include venous return issues, oncotic pressure (problems with protein), lymphatic obstruction, and sodium retention (too much salt, kidney issues).
    • Edema is the accumulation of fluid in tissues, which may include swollen feet or pulmonary edema.
    • Hyperemia, congestion, hemostasis, thrombosis, embolism, and infarction are defined with associated clinical examples.

    Hemostasis

    • Hemostasis is the process of blood clotting.
    • Arteriolar vasoconstriction, platelet plug formation (primary hemostasis), and fibrin clot formation (secondary hemostasis) are primary components.
    • Clot stabilization and resorption are described, including the roles of tissue plasminogen activator (t-PA) and plasmin.
    • Key tests to assess clotting disorders are presented.
    • Heparin acts as an anticoagulant by activating antithrombin.

    Renin, Angiotensin, Aldosterone

    • The renin-angiotensin-aldosterone system (RAAS) is a hormonal pathway that regulates blood pressure.
    • Blood pressure, distal tubular sodium, renin, angiotensinogen, angiotensin I, angiotensin II, and aldosterone secretion cause vasoconstriction, increased blood pressure, and increased cardiac output.
    • Feedback mechanisms within the system help maintain homeostasis.
    • ACE (angiotensin-converting enzyme) converts angiotensin I to angiotensin II in the lungs.
    • Angiotensin II constricts blood vessels, increases blood pressure, and stimulates the release of aldosterone from the adrenal cortex.

    BP Regulation

    • Blood pressure regulation involves the coordinated actions of kidneys, adrenals, and the heart.
    • Kidneys maintain salt and regulate the renin-angiotensin-aldosterone system.
    • Myocardium releases natriuretic peptides to inhibit sodium reabsorption when volume expansion is detected.
    • Blood pressure regulation maintains homeostasis.

    Thrombi and Emboli

    • Thrombi are blood clots formed inside a blood vessel.
    • Emboli are detached blood clots that travel through the circulatory system.
    • Formation and morphology of arterial/cardiac and venous thrombi is discussed.
    • Embolism, thromboembolism, and different types of emboli (pulmonary, systemic) are detailed.

    Infarct

    • An infarct is an area of tissue death caused by ischemia (lack of blood flow).
    • Different types of infarcts (white and red) as well as factors impacting outcome are presented.
    • Common locations where infarcts develop are discussed.

    Hypercoagulability

    • Factors like Factor V Leiden mutations, antithrombin III deficiency, Protein C and S deficiency, immobility, cancer, surgery, etc. increase risk of clotting.
    • Other factors like tissue injury, prosthetic valves, anti-phospholipid antibody syndrome, smoking, atrial fibrillation, pregnancy, and oral contraceptives increase clotting risk.

    Shock

    • Definition of shock is presented; either decreased cardiac output or decreased circulating blood volume.
    • Types of shock (cardiogenic, hypovolemic, septic) are categorized and associated clinical examples are listed.
    • The associated mechanisms and clinical presentations for different types of shock are described.

    Vasculature

    • Normal vessel structure, including layers (intima, media, and adventitia) and separate layers (internal/external elastic lamina).

    Vascular Disease

    • Clogging the pipe (e.g., atherosclerosis).
    • Weakening the pipe (e.g., aneurysms).
    • Born with bad pipes (e.g., congenital anomalies like Marfan syndrome).

    Aortic Dissection

    • Dissection includes blood splitting the layers of the arterial wall causing massive hemorrhage.

    Atherosclerosis

    • Atherosclerosis involves friable lipid cores with necrotic debris covered by a fibrous cap.
    • Rupture of the fibrous cap leads to thrombus formation, vessel-wall expansion, aneurysm, and potential rupture.

    Hypertension

    • Types of hypertension are differentiated between primary (essential) and secondary hypertension.
    • Blood pressure classifications are shown.
    • Important sequelae (e.g., cardiac hypertrophy, heart failure, CVA) are described.

    Vasculitis and Vascular Tumors

    • Types, presentations, and pathogeneses of different vasculitides are outlined.
    • Classification and examples of vascular tumors are provided, including hemangioma, Kaposi sarcoma, and angiosarcoma.

    Familial Hypercholesterolemia

    • Lipoproteins, including LDL and HDL, are categorized.
    • Disease etiology, incidence, pathogenenesis, phenotype, and natural history and management are detailed.
