MEDICATIONS: HEART DISEASE AND MEDICATIONS
Sometimes, medications may be needed to help prevent or control coronary
heart disease (CHD) and so reduce the risk of a first or repeat heart attack.
But, if medications are needed, lifestyle changes still must be undertaken.
If prescribed, take medications as directed by your health care provider.
Drugs used to treat CHD include:
· Aspirin — Aspirin helps to lower the risk of a
heart attack for those who have already had one. It also helps to keep arteries
open in those who have had a previous heart bypass or other artery-opening
procedure such as coronary angioplasty. Because of its risks, aspirin is not
approved by the Food and Drug Administration for preventing heart attacks in
healthy individuals. It may be harmful for some persons, especially those with
no risk of heart disease. Patients must be assessed carefully to make sure the
benefits of taking aspirin outweigh the risks. Talk to your doctor about whether
taking aspirin is right for you. Aspirin is now given to all patients who arrive
at the hospital emergency department with a suspected heart attack. Aspirin acts
to thin the blood and lessen the size of a blood clot during a heart attack.
· Digitalis — makes the heart contract harder and
is used when the heart's pumping function has been weakened; it also slows some
fast heart rhythms.
· ACE (angiotensin converting enzyme) Inhibitor —
stops the production of a chemical that makes blood vessels narrow and is used
to help control high blood pressure and for damaged heart muscle. It may be
prescribed after a heart attack to help the heart pump blood better. It is also
used for persons with heart failure, a condition in which the heart is unable to
pump enough blood to supply the body's needs.
· Beta Blocker — slows the heart and makes it beat
with less contracting force, so blood pressure drops and the heart works less
hard. It is used for high blood pressure, chest pain and to prevent a repeat
heart attack.
· Nitrates (including nitroglycerine) — relaxes
blood vessels and stops chest pain.
· Calcium Channel Blocker — relaxes blood vessels
and is used for high blood pressure and chest pain.
· Diuretic — decreases fluid in the body and is
used for high blood pressure. Diuretics are sometimes referred to as "water
pills."
· Blood Cholesterol-Lowering Agents — decrease LDL
cholesterol levels in the blood.
· Thrombolytic Agents — also called "clot busting
drugs," they are given during a heart attack to break up a blood clot in a
coronary artery in order to restore blood flow. The drugs prevent or limit heart
muscle damage by dissolving clots that block an artery. This opens up the artery
and restores the blood flow.
Clot-busting drugs must be given immediately after heart attack symptoms
begin. The sooner they are started, the more good they do — and the greater the
chances are of a full recovery. To be most effective, they need to be given
within 1 hour of the start of heart attack symptoms.
Drugs can cause side effects. If side effects occur, report them to your
doctor. Often, a change in the dose or type of a medication, or the use of a
combination of drugs can stop the side effect.
