Cardiovascular Drugs Flashcards
The _________________is composed of the heart and blood vessels.
Circulatory System
It is the amount of tension (stretch) applied to a muscle before contraction = force of venous return
Preload
It is the amount of tension (stretch) applied to a muscle before contraction = force of venous return
Preload
The load against which a muscle exerts its force = arterial pressure that the left ventricle overcomes to eject blood
Afterload
It is controlled by the ANS
Heart Rate
It is determined by myocardial contractility (force with which the ventricles contract),
Stroke Volume
Major risk factor for Coronary Artery Disease (CAD) Cardiovascular Disease (CVD) and death
Hypertension
Determined by the product of cardiac output and systemic vascular resistance
Bloop Pressure
Drugs that accelerate the rate of urine formation that results to the removal of sodium and water from the body
Diuretics
The spasms of the smooth muscle that surrounds the coronary arteries and occurs at rest without any triggers but usually occurring at the same time of day
Vasospastic Angina
It is the intense but subsides within 15 mins of rest or medication and 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
An early stage of progressive artery disease characterized by pain increasing in severity and frequency and may even occur at rest
Unstable Angina
The amount of blood ejected with each contraction (65% of total ventricle volume)
Ejection Fraction
Occurs due to a reduced ratio of ejection fraction to left-ventricular end-diastolic volume
Heart Failure
It is the total amount of blood in the ventricle before contraction
LV End-diastolic volume (EDV)
