Stents used to open Heart artery. Heart blockage is 80 to 85%?
what is risk in stents used to open heart artery. what actually is stent. what are the advantages and disadvantage of using stent ? is there any other better option? Blockage of artery is 80% and 85%.
If there is 80-85% blockage, either CABG or angioplasty/stenting is needed. If an artery is blocked, there will be reduced blood flow to the heart and most people with 80-85% blockage experience regular episodes of angina. Stents are basically a wire metal mesh tube which is used to open an artery with angioplasty. This is what it looks like:-http://www.ipadrblog.com/stents1.jpg
And this is how it’s used in an artery:-

The procedure is done during angioplasty, a catheter will be inserted into a blood vessel in the groin or arm, the stent is collapsed and placed over a balloon catheter. It’s then passed to the blocked artery, where they will inflate the balloon and expand the stent in the artery. The main aim is to improves blood flow to the heart which will reduce episodes of angina. The stent stays in the artery forever and will hold it open.
The risks are rare and the benefits outweigh the risks. Serious complications include an allergic reaction to the dye which is used during angioplasty (to highlight the arteries on x-ray). In about 1 in 100 cases, the stent can completely block the artery, if this happens you will require an immediate CABG.
In less than 100 cases a heart attack or stroke can occur and in less than 1 in 200 cases the stent can damage the artery. This is quite rare but would require emergency surgery.
The main pros of having stenting as opposed to a CABG is obviously that there are far less risks involved. Open chest surgery carries far higher risks and the recovery time is much longer. Other factors come into it too. In some cases, a CABG might not be the best option. Age and overall health are taken into consideration.
One long term problem with stenting is that the plaque build up in the artery (which has initially caused the narrowing) can return inside the stent and cause narrowing again. This is less likely to happen if you make appropriate lifestyle changes. Soon all stents will be coated with a chemical to prevent growth of atheroma.
A CABG does offer better survival rates compared to other therapy, but as I mentioned above, the procedure carries more risks and the benefits may not outweigh the risk if only one or two arteries are blocked. Also, with CABG, the degree of improvement decreases after five years.
The use of coronary stents reduces the need for repeat revascularisation when compared with previous studies that used balloon angioplasty, though the rate remains significantly higher than in patients managed with CABG. Coronary stenting for multivessel disease offers the same degree of protection against cardiovascular events as CABG, but stenting is associated with a greater need for repeated revascularisation.
To sum up, If you have single-vessel coronary artery disease, angioplasty/stenting offers better relief of angina than drug therapy and carries less risks than the CABG

Those are good questions which you should ask your cardiologist or cardiac surgeon. I can tell you that stents are usually made of metal with some sort of coating. They act like drainpipes which carry rainwater away from low spots in gutters. They hold the artery open and you may have to take some drugs for a while while your body heals around them. Eventually, you should be able to stop the drugs and live a normal life. The advantage is that they’re easy to insert most of the time, require only a slight opening, and allow you to continue a normal life in most ways. A good place to look for more information is WebMD.com

In medicine, a stent is a man-made ‘tube’ inserted into a natural passage/conduit in the body to prevent, or counteract, a disease-induced, localized flow constriction. The term may also refer to a tube used to temporarily hold such a natural conduit open to allow access for surgery.
A coronary stent is a stent placed in a coronary artery to treat coronary heart disease as part of a procedure called percutaneous coronary intervention (PCI).
If the blockage is in the left main coronary arery, open heart surgery is preferable in the long run even though it is costly.

Stenting of coronary arteries is a very common and very safe procedure. In adults this is often performed under local anaesthesia. A tube is passed often from your femoral vessels (groin) in to your heart. It is then placed into the blocked vessel, the cardiologist will then pass a guidewire across the narrowing and may use a balloon to open it up first prior to inserting the stent.
Once the stent is positioned it is released depending on the severity of the problem etc will determine they type of stent used. Most likely it will be a drug eluting stent.
Often the cardiologist will not decide the stent he will use until during the procedure. The procedure is likely to last 1-2 hours on average.
Stents are made from a range of materials including titanium, nickel and platinum.
Stenting offers a low risk high success rate to the management of coronary heart disease, the alternative being open heart surgery.

I believe that there are better options, when I had horrible painful chest pains I took 3 plastic spoons of Cayenne red chilli pepper with 2-3 spoons of honey & drank it down with a mug of Green tea. I ate blueberries too. I haven’t had chest pains since (9years) but I try to avoid eating all those bad things as below. So Cayenne pepper, green tea & blueberries must of been good for my heart. I also drank charcoal water which seemed to help very much.

Have you read about Chinese or Indian Herbal Medicine?
Often you can make food your medicine & fix yourself.
I like -
hyperhealth.com – type in the problem & see all the food & herbs that may help health problems / sickness
alternativescentral.com – wonderful gemstone & herbal elixirs
vitalityplusaustralia.com – has the best & fastest detox – an ionic foot bath, it is shocking to see the yukky toxins come out of the feet
Some of my favourite books are -
The Cure for All Diseases by Hulde Clark which recommends a herbal parasite detox & avoidance of all chemicals. I had to do this programme to get better & improve my health.
Back to Eden by Jethro Kloss
The Complete Book of Ayurvedic Home Remedies by Vasant Lad
Healing by God’s Natural Methods by Al Wolfsen
The World’s Greatest Treasury of Health Secrets
You will get better much faster if you avoid these things -
cheese, pig meat, no soy milk or foods, yeast bread & beer, cold fizzy drinks, fried food, canola oil or margarine, ice-cream, milk, chlorinated pools / shower / drinking water, homogenised milk, white flour / rice / sugar / salt, microwaved foods, non stick cookware, metal cutlery.
Also try to avoid any chemical product like shampoo, dish detergent, after shave, shave foam, air freshener , bleach etc
I use baking soda mixed with apple cider vinegar or filtered water with 10 drops of Lavender or Tea Tree oil for a shampoo.
Investigate & decide for yourself!
Cheers!
