 Vaccines have done such a good job of controlling diseases in developed countries, such as the United States, that parents sometimes forget just how important they are and what life would be like without them.You don’t need a time machine to see kids dying of measles, pertussis, Haemophilus influenzae type b disease, rotavirus, or Streptococcus pneumoniae meningitis though, just a few of the vaccine preventable illnesses that kids in the United States are routinely immunized against. Unfortunately, these infections are still killing millions of children around the world. |

The heart is a muscle. It pumps oxygen-rich blood to all parts of the body. When you have heart failure, the heart can’t pump as well as it should. Blood and fluid may back up into the lungs, and some parts of the body don’t get enough oxygen-rich blood to work normally. These problems lead to the symptoms you feel.
When You Have Heart FailureBecause of heart failure, not enough blood leaves the heart with each beat. There are two types of heart failure. Both affect the ventricles’ ability to pump blood. You may have one or both types.  |  | | Systolic heart failure: The heart muscle becomes weak and enlarged. It can’t pump enough blood forward when the ventricles contract. Ejection fraction is lower than normal. | Diastolic heart failure: The heart muscle becomes stiff. It doesn’t relax normally between contractions, which keeps the ventricles from filling with blood. Ejection fraction is often in the normal range. |
How Heart Failure Affects Your BodyWhen the heart doesn’t pump enough blood, hormones (body chemicals) are sent to increase the amount of work the heart does. Some hormones make the heart grow larger. Others tell the heart to pump faster. As a result, the heart may pump more blood at first, but it can’t keep up with the ongoing demands. So, the heart muscle becomes more damaged. Over time, even less blood is pumped through the heart. This leads to problems throughout the body. What Is Ejection Fraction?Ejection fraction (EF) measures how much blood the heart pumps out (ejects). This is measured to help diagnose heart failure. A healthy heart pumps at least half of the blood from the ventricles with each beat. This means a normal ejection fraction is around 50% or more. |

This is now implemented by inserting a Read more... tag (the button is located below the editor area) a dotted line appears in the edited text showing the split location for the Read more.... A new Plugin takes care of the rest. It is worth mentioning that this does not have a negative effect on migrated data from older sites. The new implementation is fully backward compatible. |
