Research Update on Coronary Heart Disease
Should You Be Taking a Polypill?
Taking a combination of medications for your heart may be more beneficial than taking a single drug, according to a study in the British Medical Journal. The researchers followed 13,029 men and women diagnosed with coronary heart disease between 1996 and 2003, to look at how the medications they were taking affected their lifespan. They found that individuals who took a combination of aspirin, a statin, and a beta blocker had an 83% lower risk of dying, compared to those not taking any medications. That compared with a 47% reduced risk in those taking a statin alone, 41% with aspirin alone, and 19% with a beta-blocker alone.

How Safe Is Crestor?
When it comes to statin drugs, Crestor is just one choice.
For some people, lifestyle changes are all that are needed to control risk factors for coronary heart disease. However, when these measures fail to produce the desired results, medications can be added. Not only can drugs control blood lipids, but they can also help lower blood pressure as well as decrease the risk of blood clots and bouts of angina. Remember that continuing your lifestyle changes will help make these drugs more effective and may allow you to take a lower dose of medication, reducing your likelihood of experiencing side effects.

Angina is a warning sign that your heart needs more oxygen. In technical terms, the symptoms of angina are the result of myocardial ischemia (a shortage of blood and oxygen to the heart muscle due to the partial blockage of a coronary artery by the buildup of plaque).
