Definition

In heart failure, the heart is unable to pump the right amount of blood throughout the body. This causes blood to back up in the veins. Depending on which part of the heart is affected, this can lead to a buildup of excess fluid in the lungs, feet, and elsewhere. Heart failure can worsen with time, which may lead to the use of many treatments. Because of this, doctors are aggressive in treating heart failure to try to prevent it from worsening.

The study supports proper prenatal care advice which advocates for mothers to exercise during pregnancy if allowed by the physician.
