Medicines for Heart Disease

You will likely take several types of medicine for your heart disease. Some of the medicines reduce the chance of heart attack and stroke. Others control blood pressure and cholesterol. You may also take medicines for other heart problems, such as heart failure or irregular heart rhythm (arrhythmia). And other health conditions such as diabetes likely also need medicines. Keeping track of your medicines and knowing what each does can get confusing.
