Drugs that primarily cause arterial and cenous dilation through their action on peripheral sympathetic neurons

pg. 351

Medications used to treat hypertension

pg. 349

The amount of blood ejected from the left ventricle, measured in liters per minute

pg. 348

Drugs that modify the funciton of the sympathetic nervous system in the brain by stimulating alpha₂ receptors. Alpha₂ receptors are inhibitory in nature and thus have a reverse sympathetic effect and cause decreased blood pressure

pg. 351

Elevated systemic arterial pressure for which no cause can be found; also called primary or idiopathic hypertension

pg. 349

A common, often asymptomatic disorder in which systolic blood pressure persistently exceeds 140mmHg and/or diastolic pressure exceeds 90mmHg

pg. 348

A common adverse effect of adrenergic blocking drugs involving a sudden drop in blood pressure from a seated or horizontal postion

pg. 352

A drug that is inactive it its given form, and which must be metabolized to its active form in the body, generally by the liver, to be effective

pg. 354

High blood pressure caused by another disease such as renal, pulmonary, endocrine, or vascular disease

pg. 349

Chest pain that occurs when the heart's supply of blood carrying oxygen is insufficient to meet the demands of the heart

pg. 369

A common form of arteriosclerosis involving deposits of fatty, cholesterol-containing material (plaques) within arterial walls

pg. 369

Chronic Stable Angina

Chest pain that is primarily caused by the atherosclerosis, which results in a long-term but relatively stable level of obstruction in one or more of the coronary arteries

pg. 369

Arteries that deliver oxygen to the heart muscle

pg. 369

Any one of the abnormal conditions that can affect the arteries of the heart and produce various pathologic effects, especially a reduced supply of oxygen and nutrients to the myocardium

pg. 369

Poor blood supply to an organ

pg. 369

Poor blood supply to the heart via the coronary arteries

pg. 369

Myocardial Infarction (MI)

Necrosis of the myocardium following interruption of blood supply; it is almost always caused by atherosclerosis of the coronary arteries and is commonly called a heart attack

pg. 369

A rapid heartbeat caused by a variety of autonomic nervous system effects, such as blood pressure changes, fever, or emotional stress

pg. 371

Early stage of progressive coronary artery disease

pg. 369

Ischemia-induced myocardial chest pain caused by spasms of the coronary arteries; also referred to as Prinzmetal or variant angina

pg. 369

A common cardiac dysrhythmia with atrial contractions that are so rapid that they prevent full repolarization of myocardial fibers between heartbeats

pg. 387

A property of specialized excitable tissue in the heart that allows self-activation through the spontaneous development of an action potential, such as in the pacemaker cells of the heart

pg. 385

Drugs that influence the rate of the heartbeat

pg. 384

Drugs that influence the conduction of electrical impulses within the tissues
