Chest X-rays can show your doctor if you have any fluid in your lungs that can be caused by heart failure. X-rays can also show changes to the size and shape of your heart.
Your doctor may ask that you undergo a catheterization (or “cath”). A “cath” is a procedure performed while you are sleepy/sedated. A doctor will use a long IV to measure the pressures inside your heart and lungs that you can’t measure with just a blood pressure cuff. A cath will give you a better understanding of how well your blood is moving around your body. The information taken from a “cath” can be very useful in helping your doctor figure out how best to treat your heart failure.
