Finals: Cardiovascular Drugs Flashcards
It is composed of the heart and
blood vessels.
Circulatory System
2 Primary functions of the Circulatory System
delivery of essentials to cells
Removal of carbon dioxide and
metabolic wastes from cells/ Fights Infection
Determinants of Cardiac Output
HEART RATE
STROKE VOLUME
PRELOAD
AFTERLOAD
Defined as a persistent systolic pressure of
greater than 140mmHg and/or a diastolic pressure
of greater than 90mmHg
Hypertension
Determined by the product of cardiac output and systemic vascular resistance
Blood Pressure
It is the amount of blood ejected from the left ventricle and measured in Lpm
Cardiac Output
It is the resistance to blood flow that is determined by the
diameter of the blood vessels and vascular musculature
Systematic Vascular Resistance (SVR)
GOAL OF ANTIHYPERTENSIVE THERAPY
Reduction of cardiovascular and renal morbidity and mortality
Drugs that accelerate the rate of urine formation
that results in the removal of sodium and water from the body
Diuretics
Acts on the brain by decreasing NE production
Central Acting
Used for the prevention of migraine headaches
and severe dysmenorrhea, mgt of opioid, nicotine
and alcohol withdrawal
Clonidine
Type of Agina that is 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 Agina
Type of Agina is when an early stage of progressive artery disease is characterized by pain increasing in severity and frequency and may even occur at rest
Unstable Agina
type of Agina that is from spasms of the smooth muscle that surrounds the coronary arteries and occurs at rest without any triggers but usually occurs at the same time of day
Vasospastic Angina
Mainstay prophylaxis and treatment for angina
Nitrates and Nitrites
