Cardiovascular Drugs

Cardiovascular medication, any agent which affects heart and blood vessel function. Drugs which affect the cardiovascular system are among the most widely used in medicine. Examples of conditions where these medications may be useful include hypertension ( high blood pressure), angina pectoris (chest pain arising from insufficient blood flow through the coronary arteries to the heart muscle), heart failure (insufficient heart muscle production compared to the needs of the rest of the body), and arrhythmias (cardiac rhythm disturbances). Drugs affect the heart function in three principal ways. They may affect the force of heart muscle contraction (inotropic effects); they may affect heart beat frequency, or heart rate (chronotropic effects); or they may affect heart beat regularity (rhythmic effects).
