Cardiovascular Medications Prepared by: Angela Kate L. Garcia, RN Hemostasis - “hem-” means blood and “- stasis” means to stop - is the stopping of blood flow. It is an essential mechanism that protects the body from both external and internal injury - is achieved once a blood clot is formed and the body is protected from excessive hemorrhage - involves a number of clotting factors that are activated in a series of sequential steps Basic steps in hemostasis: o Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. o Coagulation Cascade is a series of steps in response to bleeding caused by tissue injury, where each step activates the next and ultimately produces a blood clot. o Intrinsic Pathway is activated in response to o Extrinsic Pathway injury. is activated when blood leaks out of a vessel and enters tissue spaces. o Fibrinogen, also known as clotting factor I, forms fibrin that binds together platelets and some plasma proteins in a hemostatic plug. o Prothrombin, also known as clotting factor II, activates thrombin. Anticoagulants - are drugs used to prolong bleeding time and thereby prevent blood thrombi from forming or growing larger. - impart a negative charge to the surface of the platelets, which inhibits the clumping action or aggregation of these cells. - The process of clot removal is called fibrinolysis.  Heparin Sodium - acts by enhancing actions of antithrombin III. Antithrombin III is a protein in plasma that inactivates thrombin, and several other procoagulant enzymes, and inhibits coagulation. - Within minutes after IV administration, the loss of activated clotting factors prevents the formation of fibrin clots. - Heparin molecules have been shortened and modified to create a newer class of drugs called low- molecular-weight heparins (LMWHs). - Heparin is also called unfractionated heparin to distinguish it from the LMWHs.  Enoxaparin Sodium - low-molecular-weight heparin (LMWH) - The mechanism of action and use are similar to that of heparin, except their inhibition is more specific to active Factor X and has a longer half-life than heparin. - Duration of action is two to four times longer than that of heparin. - LMWH produces a more stable response than heparin—fewer follow-up laboratory tests are needed. - preferred drugs for a number of clotting disorders, including the prevention of DVT following surgery—less likely to cause thrombocytopenia Name: Heparin Sodium NURSING INTERVENTION Therapeutic Class: Anticoagulant (Parenteral)  Monitor aPPT (activated partial Pharmacologic Class: Indirect thrombin thromboplastin time) inhibitor  Monitor platelet count  When administering heparins via SC, inject ACTIONS AND USES into abdomen with a 25-28 G needle at a 90º Heparin is a natural substance found in the liver angle.

It is also approved for thrombi prophylaxis in patients with unstable angina, including those who are receiving vascular bypass procedures or PCI. It may be given off-label Positive Inotropic and Cardiotonic Medications A change in contractility of the heart is called inotropic effect. Drugs that increase contractility are called positive inotropic agents. Examples of positive inotropic drugs: epinephrine, norepinephrine, thyroid hormones, and dopamine Drugs that decrease contractility are called negative inotropic agents. Examples include quinidine and beta-adrenergic antagonists such as propranolol.  These are used for short-term management of Dopamine advanced heart failure—the increase in  used as a short-term rescue myocardial contractility improves cardiac, measure for clients with severe, peripheral, and kidney function by increasing acute heart failure cardiac output, decreasing preload, improving  increases myocardial blood flow to the periphery and kidneys, contractility, thereby improving decreasing edema, and increasing fluid retention. cardiac performance As a result, fluid retention in the lungs and extremities is decreased.
