Heart failure occurs when a permanent obstacle in the blood circulation is located in the body. This can be located inside or outside the heart muscle, which causes an increase in blood pressure. There are two types of heart failure: systolic, when the myocardium can not pump blood and expel it from the heart; And diastolic, when the heart muscles are rigid and not filled with blood. Both have treatment. First, any work-overloading work on the heart should be avoided, and then administering drugs that provide vitality to the exhausted heart muscle. In addition, when the obstacle is inside the coronary arteries it is spoken of coronary insufficiency.
