Risks and Benefits of Medicines for Heart Failure
Heart failure is a very serious illness that can cause life-threatening complications and significantly limit your life span.

Each of these medicines has risks and benefits that you and your doctor will need to weigh when you are deciding whether you should take the medicine.

How do medicines prolong survival?
Several medicines may help increase the life span of people who have heart failure. These include:
The exact mechanism by which these medicines prolong survival is not entirely clear. Each medicine might have several beneficial effects for people with heart failure. In terms of prolonging survival, the most important effects may be the ability of these drugs to prevent both lethal abnormal heart rhythms and their ability to limit ongoing damage to the heart.
Tailor the decisions you make with your doctor to meet your own personal goals of treatment for your heart failure. Some decisions are not always completely right or wrong. What is most important is that you make informed decisions that are right for you and with which you are comfortable.
In fact, your goals of treatment may change over time. Early in the course of your treatment, you may want to do everything possible to extend your life span, even if it means making your symptoms temporarily worse. A good example of this is starting therapy with a beta-blocker, which can make your symptoms worse during the first few weeks or months but eventually may reduce your symptoms and prolong your survival.
But if you develop end-stage heart failure with very severe symptoms that prevent you from doing even simple activities, you may prefer treatments that are most effective at reducing your symptoms, even if they may have some risk of decreasing your survival.
To help you with decision making, the most important things you can do are: first, keep yourself well informed about the risks and benefits of the treatments that are available to you, and second, work closely with a doctor whose advice and opinions you trust.
