Coronary Heart Disease (cont.)
IN THIS ARTICLE
Medical Treatment: Medications
Coronary artery disease decreases blood supply to the heart from the blocked coronary artery. The lower blood flow may fail to meet the heart's demand for oxygen. Treatment aims to balance blood supply to the heart with heart oxygen demand, and prevent worsening of coronary heart disease.
Aspirin: When taken daily or every other day, aspirin reduces the risk of developing angina or heart attack by reducing the tendency of your blood to clot.
Beta-blockers: Beta-blockers decrease your heart rate and blood pressure, thus reducing your heart's demand for oxygen. Clinical trials have shown prevention of future heart attacks and sudden death.
Nitroglycerin: This medication reduces chest pain both by decreasing your heart's oxygen demand and by dilating the coronary arteries, increasing the oxygen supply.
Calcium channel blockers: Calcium channel blockers dilate the coronary arteries to improve blood flow. They also reduce blood pressure, and slow heart rate.
ACE inhibitors: Angiotensin-converting enzyme (ACE) inhibitors work by dilating blood vessels, increasing blood flow.
