What are some preventative test you can take to prevent congestive heart failure? what are the signs? what is congestive heart failure and how is it caused, and what is the result of the body after congestive heart failure?

Congestive : Congestive heart failure (CHF) is a condition in which the heart is unable to move blood efficiently, and fluid builds up in the lungs and the tissues of the body (especially the legs). It is the common end result of a variety of problems, including direct injury to the heart, kidney failure, and lung disease, among others. The best way to prevent CHF is to eat a healthy diet, avoid tobacco, exercise regularly, and keep your cholesterol and blood pressure under control. If you already have problems with your heart, kidneys, etc, then it's important that you take whatever medications your doctor has prescribed and try to control the other items mentioned as much as possible.
