Cardiovascular Drugs Flashcards
It has two primary functions, delivery of oxygen, nutrients, hormones, electrolytes, and other essentials to cells and removal of carbon dioxide and metabolic wastes from cells. In addition, the system helps fight infection.
Circulatory System
The _____ is the pump that moves blood through the
arterial tree.
Heart
Transport blood under high pressure to tissues.
Arteries
Control valves that regulate local blood flow.
Arterioles
Controlled by the ANS
Heart rate
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
Acts on the ascending LoH, blocks Cl and Na resorption, activate prostaglandins leading to vasodilation.
Bumetanide, Furosemide,
Torsemide
Acts on the ascending LoH, blocks Cl and Na resorption, activate prostaglandins leading to vasodilation.
Bumetanide, Furosemide, Torsemide
A non-absorbable solute that works on the entire nephron esp. LoH and PCT. Increases osmotic pull the filtrate which produces a rapid diuresis.
Mannitol
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
From 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
Early stage of progressive artery disease characterized by pain increasing in severity and frequency and may even occur at rest.
Unstable Angina
Occurs due to a reduced ratio of ejection fraction to left-ventricular end-diastolic volume.
Heart Failure
Potent vasodilator and decreases systemic vascular resistance.
ARB
