If you or your child has been diagnosed with asthma, work with your doctor to learn how manage it yourself. You can work with your doctor to develop a treatment plan, called an asthma action plan.

Your doctor may recommend a stent to provide support inside an artery that has become narrowed by plaque buildup from atherosclerosis, or for lung airways that have narrowed due to other medical conditions. Your doctor will discuss the risks and benefits of the procedure with you. Sometimes, a stenting procedure is not recommended or another procedure is recommended instead. Learn more about the use of stents in the following conditions.

Having a stent placed is a minimally invasive procedure, meaning it is not a major surgery. Stents for coronary arteries and carotid arteries are placed in similar ways. A stent graft is placed to treat an aneurysm in a procedure called aortic aneurysm repair. Airway stents are placed in a procedure that helps open airways in the lung. For most stents, you will be given medicine to make you sleep during the procedure. The stent procedure may be planned ahead of time or it may be performed in an emergency situation.

It is important that you receive follow-up care, know about the possible complications that may occur after the procedure, and follow the treatment plan that your doctor recommends for your condition.

You may have an increased risk for conduction disorders because of your age, family history and genetics, medical conditions, medicines, race or ethnicity, or sex. These factors can differ by the type of conduction disorder you have.

Signs and symptoms of RDS usually happen at birth or within the first few hours that follow. Depending on the severity of a newborn's RDS, he or she may develop bronchopulmonary dysplasia or other medical problems, such as bleeding in the brain, kidney failure, or lung complications.

Newborns who are born early—usually more than 10 weeks before their due dates—and still need oxygen therapy by the time they reach their original due dates are diagnosed with BPD.

Many people who have conduction disorders, such as first-degree AV block, may have no obvious signs or symptoms. Others may have signs and symptoms that occur in specific situations, such as when you experience physical or emotional stress or when you sleep. Conduction disorders can lead to life-threatening arrhythmias if undiagnosed or untreated.

Many babies who develop BPD are born with serious respiratory distress syndrome (RDS). A first sign of BPD is when premature newborns—usually those born more than 10 weeks early—still need oxygen therapy by the time they reach 36 weeks gestation.

Age, race, gender, certain medical conditions—high blood pressure, diabetes, brain aneurysms, and heart diseases—smoking, and family history can raise your risk for a stroke.
