Pharmacology for Technicians – CH 12

A drug that prevents clot formation by affecting clotting factors.

A drug that reduces the risk of clot formation by inhibiting platelet aggregation.

Beta blocker
A Class II antiarrhythmic drug that competitively blocks response to beta adrenergic stimulation and therefore lowers heart rate, myocardial contracility, blood pressure, and myocardial oxygen demand; used to treat arrhythmias, MIs, and angina.

Blood pressure (BP)
The result of the heart forcing the blood through the capillaries; measured in millimeters of mercury, both when the heart is contracting and forcing the blood (systolic) and when the heart is relaxed and filling with blood (diastolic).

Calcium Channel Blocker
A Class IV antiarrhythmic drug that prevents the movement of calcium ions through slow channels; used for most supraventricular tachyarrhythmias and in angina.

Cardiovascular (CV)
Pertaining to the heart and blood vessels.

An odorless, white, waxlike, powdery substance that is present in all foods of animal origin but not in foods of plant origin; circulates continuously in the blood for use by all body cells.

Congestive Heart Failure (CHF)
A condition in which the heart can no longer pump adequate blood to the body’s tissues; results in engorgement of the pulmonary vessels.

Elevation of the levels of one or more of the lipoproteins in the blood.

Elevated blood pressure, where systolic blood pressure is greater than 140 mm Hg and diastolic pressure is greater than 90 mm Hg.

Myocardial Infarction (MI)
A heart attack; occurs when a region of the heart muscle is deprived of oxygen.

Pulmonary Embolism (PE)
Sudden blocking of the pulmonary artery by a blood clot.

The result of an event (finite, ongoing, or protracted occurrences) that interrupts oxygen supply to an area of the brain; usually caused by cerebral infarction or cerebral hemorrhage.

Transient Ischemic Attack (TIA)
Temporary neurologic change that occurs when part of the brain lacks sufficient blood supply over a brief period of time; may be a warning sign and predictor of imminent stroke.

Unstable angina
A type of angina characterized by chest pain that occurs with increasing frequency, diminishes the patient’s ability to work, and has a decreasing response to treatment; may signal an oncoming MI.
