If your doctor finds a blockage during your coronary angiogram, he or she may decide to perform angioplasty and stenting immediately after the angiogram while your heart is still catheterized. Your doctor will give you instructions to help you prepare.
By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said.
A completely blocked coronary artery will cause a heart attack. The classic signs and symptoms of a heart attack include crushing chest pain or pressure, shoulder or arm pain, shortness of breath, and sweating. Women may have less typical symptoms, such as neck or jaw pain, nausea and fatigue.
For most people, angioplasty greatly improves blood flow through the coronary artery and the heart. It may help you avoid the need for coronary artery bypass surgery (CABG). Angioplasty does not cure the cause of the blockage in your arteries.
In some cases, a clogged artery can cause serious symptoms and require emergency care. This primarily applies when the clogged artery is one that is supplying blood to a vital organ like the brain or heart. Call 911 or seek emergency medical care immediately if you or someone you are with has any of these symptoms.
The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.
After angiography
After the test, you'll be taken to a recovery ward where you'll be asked to lie still for a few hours to prevent bleeding from the cut. You'll usually be able to go home the same day, although sometimes you may need to stay in hospital overnight.

Through angioplasty, our cardiologists are able to treat patients with blocked or clogged coronary arteries quickly without surgery. During the procedure, a cardiologist threads a balloon-tipped catheter to the site of the narrowed or blocked artery and then inflates the balloon to open the vessel.
Many times people live happily with a blocked artery. But with one blocked artery symptoms are a high chance of reduced life expectancy. Asymptomatic patients live up to 3-5 years.
Small vessel disease signs and symptoms include: Chest pain, squeezing or discomfort (angina), which may get worse with activity or emotional stress. Discomfort in the left arm, jaw, neck, back or abdomen along with chest pain. Shortness of breath.
Heart block may resolve on its own, or it may be permanent and require treatment. There are three degrees of heart block. First-degree heart block is the mildest type and third-degree is the most severe.
What should you expect? The procedure may take place right after the arteriogram, which is used to find the blockage, or it may occur the next day. You may need to stay in the hospital two or three days.
If you had a planned (non-emergency) coronary angioplasty, you should be able to return to work after a week. However, if you've had an emergency angioplasty following a heart attack, it may be several weeks or months before you recover fully and are able to return to work.
A moderate amount of heart blockage is typically that in the 40-70% range, as seen in the diagram above where there is a 50% blockage at the beginning of the right coronary artery. Usually, heart blockage in the moderate range does not cause significant limitation to blood flow and so does not cause symptoms.
Stenting is a minimally invasive procedure, meaning it is not considered major surgery. Stents can be made of metal mesh, fabric, silicone, or combinations of materials. Stents used for coronary arteries are made of metal mesh. Fabric stents, also called stent grafts, are used in larger arteries such as the aorta.
Myth: The angioplasty procedure and stent fixed my heart problems. Fact: You should feel better immediately after your angioplasty because it opened your blocked blood vessel and blood started to flow freely.
How long will a stent last? It is permanent. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months. If it does, it can potentially be treated with another stent.
Time-in-bed standards vary widely, from 3 to 12 hours after cardiac catheterization to more than 24 hours of bed rest after angioplasty. Bed rest with restricted movement causes patient discomfort, increases nursing workload, and prolongs length of hospital stay.
Avoid playing sport, excessive activity or lifting anything heavy for about 2 days.
But, this procedure has its acute problems like bleeding and formation of hematoma in the removal place of the sheet. Based on researchers' clinical experiences, patients need a time of 8-12 hours for bed rest after coronary angioplasty.
Lower back pain: The arteries leading to the lower back are among the first in the body to accumulate plaque and show signs of blockage. In fact, 10 percent of Americans already experience advanced blockages in these arteries by age 20.
A heart attack is particularly dangerous when it's caused by blockage in the left anterior descending artery, which supplies blood to the larger, front part of the heart, earning it this scary-sounding nickname.
