Your doctor may recommend cardiac catheterization to find out what is causing signs or symptoms of a heart problem or to treat or repair a heart problem.

RDS is a type of neonatal respiratory disease that is caused most often by a lack of surfactant in the lungs. A fetus's lungs start making surfactant during the third trimester of pregnancy, or weeks 26 through labor and delivery. Surfactant coats the insides of the air sacs, or alveoli, in the lungs. This helps keep the lungs open so breathing can occur after birth.

Taking steps to ensure a healthy pregnancy might prevent your newborn from being born before his or her lungs have fully developed. Your doctor may also give you injections of a corticosteroid medicine if he or she thinks you may give birth too early. This medicine can speed up development of the lungs, brain, and kidneys in your baby and surfactant production.

Angina happens when your heart muscle does not get enough oxygen-rich blood. Medical conditions, particularly ischemic heart disease, or lifestyle habits can cause angina. To understand the causes of angina, it helps to understand how the heart works.

Your doctor will check your medical history, perform a physical exam, and do tests and procedures to diagnose cardiogenic shock. Tests are usually done after you have been admitted to a hospital for a possible heart attack or symptoms of shock. If the reason for the shock is that the heart is not pumping strongly enough, then the diagnosis is cardiogenic shock.

Signs, symptoms, and complications may differ depending on the type of bleeding disorder, its cause, and whether the disorder is mild or more serious. Signs and symptoms may be obvious soon after a child is born or not until adulthood. People who have a mild bleeding disorder may not have any signs or symptoms until they are injured or have a medical procedure.

The respiratory system helps you breathe. The main parts of the respiratory system are the lungs, the airways, and the muscles that enable breathing. The circulatory system, which is made up of the heart, veins, arteries, and capillaries, brings blood to and from the lungs and delivers nutrients and oxygen to tissues of the body while removing carbon dioxide and waste products. Other body systems that work with the respiratory system include the nervous system, lymph system, and immune system.
