Cardiovascular Drugs Flashcards
Composition of Circulatory System
Heart and Blood vessels
Transport blood under high pressure to tissues.
Arteries
Amount of tension (stretch) applied to a muscle before contraction
PRELOAD
Load against which a muscle exerts its force
AFTERLOAD
Defined as a persistent systolic pressure of greater than 140mmHg and/or a diastolic pressure of greater than 90mmHg
HYPERTENSION
Drugs that accelerate the rate of urine formation that results in the removal of sodium and water from the body
DIURETICS
Used for prevention of migraine headaches and severe dysmenorrhea, mgt of opioid, nicotine, and alcohol withdrawal
CLONIDINE
What leads to angina pectoris (chest pain) and ischemia
POOR BLOOD SUPPLY
Intense but subsides within 15 mins of rest or medication and is caused mainly by atherosclerosis and can be triggered by exertion or stress (cold, emotions) and exacerbated by smoking, alcohol, coffee, and some drugs.
CHRONIC STABLE ANGINA
The early stage of progressive artery disease is characterized by pain increasing in severity and frequency and may even occur at rest
UNSTABLE ANGINA
From spasms of the smooth muscle that surrounds the coronary arteries and occurs at rest without any triggers but usually occur at the same time of day
VASOSPASTIC ANGINA
