If you have diastolic heart failure, your left ventricle has become stiffer than normal. Because of that, your heart can't relax the way it should. When it pumps, it can't fill up with blood as it's supposed to. Because there's less blood in the ventricle, less blood is pumped out to your body.
What Causes It?
