Cardiovascular Drugs Flashcards
This is for heart failure drugs that increase the force of myocardial contraction.
Positive Inotropic drugs
A heart failure drugs that increase the rate in which the heart beats.
Positive chronotropic drugs
A heart failure drugs that accelerate conduction.
Positive Dromotropic drugs
This is amount of tension (stretch) applied to a muscle before contraction = force of venous return.
Preload
A load against which a muscle exerts its force = arterial pressure that the left ventricle overcomes to eject blood.
Afterload
Defined as a persistent systolic pressure of greater than 140mmHg and/or a diastolic pressure of greater than 90mmHg.
Hypertension
The resistance to blood flow that is determined by the diameter of the blood vessels and vascular musculature.
SVR
Drugs that accelerate the rate of urine formation that results to the removal of sodium and water from the body.
Diuretics
What do you call an early stage of progressive artery disease characterized by pain increasing in severity and frequency and may even occur at rest.
Unstable Angina
This is type of Angina that is from spasms of the smooth muscle that surrounds the coronary arteries and occur at rest without any triggers but usually occuring at the same time of day.
Vasospastic Angina
Potent vasoconstrictor and can prevent NA And water resorption Causing diuresis.
ACEI
Inhibits the action or formation of clotting factors and prevents clot from forming.
Anti-coagulants
This prevent platelet plugs forming by inhibiting platelet aggregation.
Antiplatelet
Break down clots and thrombi that have already formed.
Thrombolytic
