Sometimes VTE does not cause symptoms until serious complications occur. In other cases, deep vein thrombosis causes swelling or discomfort near the blood clot. Pulmonary embolism can cause chest pain and difficulty breathing. Pulmonary embolism can be a life-threatening condition.

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.

Typically doctors screen for atrial fibrillation only when you have symptoms. However, your doctor may check for signs of atrial fibrillation as part of your regular medical care. Screening tests include checking your pulse or recording your heart’s electrical activity.

There are two types of aortic aneurysms: thoracic aortic aneurysms and abdominal aortic aneurysms.

Causes of cardiogenic shock include heart attack and other heart problems, problems outside of the heart, and medicines or procedures. A heart attack is the most common cause because it can damage the heart’s structure in different ways. Less often, a problem elsewhere in the body blocks blood flow coming into or out of the heart and leads to cardiogenic shock.

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.

Your doctor may use diagnostic tests or procedures before CABG to determine how serious your ischemic heart disease is and where the coronary arteries are narrowed. If you need CABG, talk to your doctor about how to prepare for the procedure.
