Angioplasty is a procedure to improve blood flow in coronary arteries that have become narrow or blocked. Your coronary arteries supply oxygen-rich blood to the heart. If you have coronary artery disease, a sticky material called plaque builds up in the coronary arteries. Plaque is made of cholesterol, calcium, and other substances in your blood. Over time, it can narrow your arteries or fully block them. When this happens, some parts of your heart don't get enough blood.

Angioplasty widens the blocked part of the artery so more blood can get through. It is also called percutaneous coronary intervention (PCI).

Doctors use angioplasty to:

• Reduce chest pain from blockages in the coronary arteries. This type of pain is called angina. There are different types of angina. Angioplasty treats certain types.
• Limit damage to the heart during or right after a heart attack. In this case, angioplasty is an emergency treatment.

Angioplasty does not cure coronary artery disease. To help prevent more plaque blockages, you'll need to take any prescribed medicines, eat healthy foods, and get regular exercise.

Most people have angioplasties in a hospital in a special room called a cardiac catheterization, or cath, lab. You will be awake and lying down. You'll get medicine to help you relax through an intravenous (IV) line. This is a small tube that goes into a vein in your hand or arm.

Angioplasty is done through a blood vessel in your arm, wrist, or groin. Your doctor will:

• Make a small opening in that area to insert a thin tube (a catheter) into a blood vessel.
• Thread the tube through the vessel to your heart, using x-rays as a guide.
• Inject contrast dye inside your arteries. The dye highlights your heart and blood vessels in the x-rays.
• Replace the first tube with another one that has a small, deflated balloon on the end.
• Guide the balloon inside the blockage and inflate it to push the plaque flat against the artery wall. This makes the artery wider and improves blood flow.
• Sometimes put a small, mesh tube into the artery to help keep it open. The tube is called a stent. Some stents have a coating of medicine that helps prevent blood clots from forming.

If you had an angioplasty for chest pain, you'll go to a recovery room for a few hours. You may stay in the hospital overnight. Your doctor will probably prescribe medicines to prevent blood clots. Most people can return to their usual activities after a week.

If you had an emergency angioplasty for a heart attack, you'll need to stay in the hospital for about a few more days.

Angioplasty is very safe. You may get a bruise, feel sore, or have some bleeding where the tubes were inserted. More serious problems don't happen very often, but they are possible. They can include serious bleeding, blood clots, and narrowing of the artery again.

A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen.

There are several types of hernias, including:

• Inguinal, in the groin. This is the the most common type.
• Umbilical, around the belly button
• Incisional, through a scar
• Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest.
• Congenital diaphragmatic, a birth defect that needs surgery

Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia.

Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.

The pelvic floor is a group of muscles and other tissues that form a sling or hammock across the pelvis. In women, it holds the uterus, bladder, bowel, and other pelvic organs in place so that they can work properly. The pelvic floor can become weak or be injured. The main causes are pregnancy and childbirth. Other causes include being overweight, radiation treatment, surgery, and getting older.

Common symptoms include:

• Feeling heaviness, fullness, pulling, or aching in the vagina. It gets worse by the end of the day or during a bowel movement.
• Seeing or feeling a "bulge" or "something coming out" of the vagina
• Having a hard time starting to urinate or emptying the bladder completely
• Having frequent urinary tract infections
• Leaking urine when you cough, laugh, or exercise
• Feeling an urgent or frequent need to urinate
• Feeling pain while urinating
• Leaking stool or having a hard time controlling gas
• Being constipated
• Having a hard time making it to the bathroom in time

Your health care provider diagnoses the problem with a physical exam, a pelvic exam, or special tests. Treatments include special pelvic muscle exercises called Kegel exercises. A mechanical support device called a pessary helps some women. Surgery and medicines are other treatments.
