Heart Bypass Surgery Rate Is Declining

David’s Quadruple Bypass Story–Success!

Study Shows Drop in the Number of Heart Bypass Surgeries Performed in the U.S.

May 3, 2011 — There has been a dramatic drop in the rate of heart bypass procedures performed in the U.S. over the last decade, even though more hospitals are offering the open-heart surgery.

One-third fewer coronary artery bypass graft surgeries were performed in 2008 compared to 2001, while the rate of less invasive angioplasty procedures remained largely unchanged, according to a study in the Journal of the American Medical Association.

More than a million coronary revascularizations, involving either CABG or angioplasty with or without stenting, are performed in the U.S. each year to fix blocked arteries that supply blood to the heart.

In 2008, three out of four revascularization patients had angioplasties instead of CABG, compared to two out of three patients a decade ago, Peter W. Groeneveld, MD, of the University of Pennsylvania School of Medicine tells WebMD.

âThis is a problem, because it does actually matter which of these surgeries patients get,â he says, adding that many patients who would be expected to have better outcomes with CABG may not be offered the surgery.

Newborn Cardiac Surgery Survival

Performing heart surgery on newborn babies is more challenging due to the young age and small size of the patients. By comparing newborn survival rates along with STAT category, parents can get an idea of how well the surgeons perform in the most challenging cases.

What we measure:

We compare our survival rates for newborn patients with national averages by the complexity of the surgery.

What it means:

At Childrens Colorado, our surgeons have extensive experience correcting heart defects in even the youngest patients some just a few hours old. Our survival rates for STAT 1, STAT 2 and STAT 5 cases are higher than the national averages.

Risks Of Heart Bypass Surgery

Any Heart Bypass Surgery carries risk, given the fact that the body functions on an artificial machine while the surgery takes place. However, in the last few decades, with the innumerable technological advancements in the medical sector, certain improvements have been made which ensure a remarkable success rate of the Heart Bypass Surgery.

So How Long Does Heart Bypass Surgery Last

Lets summarize the article so far. If a patient has a LIMA bypass, it is almost 90% likely to remain open, even 10 years after the operation, and that is just great. For the other blockages where an SVG graft is used, the bypasses are about 50% likely to remain open at 10 years. If grafts go down its not necessarily a disaster, there are often good treatment options.

One Of The Central Questions

Igarni: Triple Bypass Open Heart Surgery Survival Rates

This has been one of the central questions of cardiovascular medicine for a long time: Is medical therapy alone or medical therapy combined with routine invasive procedures the best treatment for this group of stable heart patients? said study co-investigator Robert Harrington, MD, professor and chair of medicine at Stanford and the Arthur L. Bloomfield Professor of Medicine. I do see this as reducing the number of invasive procedures.

Robert Harrington

The study was designed to reflect current clinical practice, in which patients with severe blockages in their arteries often undergo an angiogram and revascularization with a stent implant or bypass surgery. Until now, there has been little scientific evidence to support whether these procedures are more effective in preventing adverse heart events than simply treating patients with medications such as aspirin and statins.

If you think about it, theres an intuitiveness that if there is blockage in an artery and evidence that that blockage is causing a problem, opening that blockage is going to make people feel better and live longer, said Harrington, who regularly sees patients with cardiovascular disease at Stanford Health Care. But there has been no evidence that this is necessarily true. Thats why we did this study.

Ischemia, which is reduced blood flow, often causes symptoms of chest pain known as angina. About two-thirds of those heart patients enrolled in the study suffered symptoms of chest pain.

Operations Performed At The Right Time Have Success Rates Of 98 Per Cent Or More Said Dr Upendra Bhalerao Consultant Cardiothoracic And Transplant Surgeon

If you have been advised a bypass surgery and are worried ahead of the procedure, do not. We are here to help you with some basic information that will surely make you comfortable and at ease.

Do not be afraid or panic. Remember, correct procedure performed by experts will improve your quality of life significantly. This surgery will only enhance your cardiac health, said Dr Upendra Bhalerao, consultant cardiothoracic and transplant surgeon, Wockhardt Hospital.

When is bypass surgery necessary?

One has to undergo bypass surgery when the coronary arteries develop multiple blockages due to accumulation of cholesterol. The surgery allows to restore the blood supply to ones heart.

However, many people refrain from undergoing the surgery owing to certain myths surrounding it. Dr Bhalerao busts some of them.

Myth 1 Cardiac surgery is very risky

Fact: With upgraded technology and medical practices, the risk associated with cardiac surgeries, like valve replacement surgery or coronary bypass surgery, is very less. Operations performed at the right time have the success rates of 98 per cent or more, he said.

Myth 2 Stents are safer than bypass surgery

Overall Mortality Rates And Survival

In total data on 33 094 interventions were extracted from the NVT national database. The study population is described in Table . The total follow-up time after intervention was 90 386.6 years and the mean follow-up time was 996.9 days. Early mortality rates using the different measures are presented in Fig. . Mortality after discharge from the primary hospital was doubled after 1 year: from 972 deaths to 2052 deaths . In-hospital and 30-day mortalities were nearly identical. However, in Table the difference between these outcome measures is shown. Approximately 20% of all deaths during admission occur after 30 days. The other way around holds true as well: 20% of all deaths within 30 days occur at home or at another care facility.

Your doctor will give you medications to help manage your pain, such as ibuprofen or acetaminophen . You may also receive a narcotic for extreme pain.

Your doctor will also give you medications to help you throughout your recovery process. These will include antiplatelet drugs and other drugs prescribed by your doctor.

Talk to your doctor about what medication plans are best for you. This is especially important if you have existing conditions such as diabetes or conditions affecting the stomach or liver.

Why Do I Need Heart Bypass Surgery

Bypass surgery treats symptoms of coronary artery disease. That happens when a waxy substance called plaque builds up inside the arteries in your heart and blocks blood and oxygen from reaching it.

Your doctor may suggest heart bypass surgery if:

  • You have severe chest pain that your doctor thinks happens because several of the arteries that supply blood to your heart are blocked.
  • At least one of your coronary arteries has disease that’s causing your left ventricle — the chamber that does most of your heart’s blood pumping — to not work as well as it should.
  • There’s a blockage in your left main coronary artery, which gives your left ventricle most of its blood.
  • You’ve had other procedures, and either they haven’t worked or your artery is narrow again.
  • You have new blockages.

Coronary artery disease can lead to a heart attack. It can cause a blood clot to form and cut off blood flow. Bypass surgery can give your ticker a big health boost.

Immediately After Heart Bypass Surgery

You should talk to the medical staff if you have any fears or anxieties over the few days immediately after the operation, as emotional stress can make demands on your heart.Following the operation:

  • You spend a day or two in the intensive care unit. You have numerous monitors attached to you that are located by your bed.
  • You have a couple of intravenous lines to keep your body fluids and electrolyte levels in balance.
  • The medical and nursing staff are trained to look out for any complications or potential complications. They keep an expert eye on your heart tracings, and treat any irregularities if they arise.
  • You have a nasogastric tube to drain any excess stomach fluids, and a tube into your bladder to drain off and measure your urine output.
  • You are shown how to care for your wounds. Often, washing with soap and water is enough.
  • You are given advice on angina , such as how to treat it and when to get medical help.
  • Your doctor advises on when you can return to work, resume driving, and exercise strenuously.
  • You are shown breathing exercises and other exercises by a physiotherapist.
  • Before you leave hospital, your doctor should provide guidelines about restarting sexual activity. You should be given advice on positions that reduce exertion during sex, and what to do if you experience angina.

Routinely Performed Coronary Artery Bypass Surgeries

  • Pumped CABG is more commonly called traditional bypass surgery.
  • During the procedure, a heart-lung machine takes over the heartâs pumping and oxygenation functions, and medicines are administered to temporarily paralyze the heart .
  • The heart is entirely at rest while the surgeon performs the bypass operation in this manner.
  • Off-pump or beating heart
  • Off-pump CABG or beating heart bypass surgery is done when a heart-lung machine is not employed, and drugs are not used to stop the heart.
  • Instead, the heart continues to pump blood and oxygenate the body as the surgeon works.
  • The surgeon stabilizes only the segment of the heart that requires the bypass, whereas the rest of the heart continues to function normally.
  • Off-pump bypass is as safe and successful as on-pump coronary bypass surgery in the right individuals according to the Journal of the American Heart Association. Many healthcare practitioners feel it may lower the risk of stroke, bleeding, and kidney failure.

    He considers it telling that off-pump coronary bypass surgeries in the U.S. dropped from 23 percent in 2002 to 17 percent in 2012.

    The vast majority of cardiac surgeons dont want to hurt their patients, and while they want to be innovative, I think when they stop doing this operation, you know that theres got to be a problem, he said.

    What Do We Mean By Survival Statistics

    The NHS monitors childrens heart surgery in the UK by reviewing each hospitals 30-day survival rate. The 30-day survival rate is the percentage of operations where the child survived to at least 30 days after their heart surgery. Ireland also submits its data to the same audit body, NCHDA.

    Approximately 3500 children under the age of 16 have heart surgery each year in the United Kingdom and Republic of Ireland.

    You May Experience Sleep Issues

    Many people complain of having trouble sleeping for some time after heart surgery. You may experience insomnia because of:

    • Effects of anesthesia

    • Changes in your daily routine

    • Stress from personal concerns

    Normal sleeping patterns typically return in two to three weeks. Until then, try these tips:

    • Take enough rest breaks in between your normal daily activities but avoid a daytime nap longer than 20 minutes.

    • If you have pain, take your pain medication about 30 minutes before bedtime.

    • Arrange the pillows so you can maintain a comfortable position and decrease muscle strain.

    • If you feel anxious or nervous, talk to your spouse, partner or a trusted friend. Get your troubles off your mind.

    • Avoid caffeine in the evenings.

    • Listen to relaxing music or a guided imagery audio program.

    • Ask your partner to give you a back rub.

    • Take a relaxing shower.

    • Follow a bedtime routine to let your body know its time to relax and get to sleep.

    • Its OK to sleep on your back, side or stomach. You will not hurt your incisions.

    Once Scary Heart Bypass Surgery Has Become Common And Safer

    Frank Vignuli couldnt be having a heart attack, could he?

    He wasnt short of breath. His chest didnt feel tight. But on the morning of Aug. 4, 2004, the 47-year-old from Wilmington, Del., didnt feel normal. His jaw was burning, his shoulder was in pain. But he didnt want to wake up his family. The port operations manager wasnt in the habit of going to the doctor or asking for help about his health.

    Finally, concerned about the ongoing sensation in his jaw, Vignuli woke his wife. Soon, he was in an emergency room, where a doctor told him he had just had a heart attack and needed quadruple bypass surgery immediately.

    Hours later, he awoke in the cardiac intensive care unit at Christiana Hospital in Newark, Del. Since then, Vignuli has lived a successful and active life once thought impossible for people with clogged arteries, which can lead to stroke, infections and heart attacks.

    He has done so thanks to a procedure once considered risky: More than 9 percent of the first 150 patients to receive the procedure at one hospital in 1966 and 1967 died before they were able to be sent home. That figure went down to 3 percent in 1999 for a large comparable group of American and Canadian patients. Today, 14 years after Vignulis surgery, deaths before being discharged from the hospital are between 1 and 3 percent, and surgeons have refined the procedure and the rehab that follows even more.

    It would take 50 more years for the surgery to succeed in a human.

    What Are The Four Types Of Heart Valves

    Cardiothoracic Surgery

    The heart is made up of four pumping chambers:

    • Two atria: Upper chambers of the heart
    • Two ventricles: Lower chambers of the heart

    There are valves between each of the heartâs pumping chambers that open and close in coordination with each other. Their action keeps blood flowing forward through the heart. There are four valves in the heart:

    • Tricuspid valve: Between the right atrium and the right ventricle
    • Pulmonary valve: Between the right ventricle and the pulmonary artery
    • Aortic valve: Between the left ventricle and the aorta

    In total, 27 articles reported on process factors of in-hospital mortality after CABG. Factors in these articles were grouped to pre-operative care , intraoperative management , and postoperative care . Of the 12 identified factors, we synthesized 11 mechanisms from 22 articles for their effect on mortality .

    What Is Recovery Like After Open

    Recovery time varies depending on the surgery type, complications and your overall health before surgery. It can take 6 to 12 weeks to recover from an open-heart procedure.

    Your surgeon will let you know when you can return to work and other activities. Typically, you shouldnt drive or lift anything heavy for the first six weeks.

    Some people need to take blood thinners after heart surgery to prevent blood clots. Your healthcare provider may also recommend cardiac rehabilitation. This medically supervised program can help you regain strength and stamina and improve overall heart health.

    What Is The Recovery Time

    Most people who have CABG will need several weeks to fully recover from this procedure. During that time, your provider will likely have you avoiding any strenuous activities or situations that might put too much stress on your heart and incisions.

    Your healthcare provider is the best person to tell you how long it will probably take you to recover and what you should expect. Theyll also tell you when you can start resuming your regular activities like work, exercising, driving, etc.

    What Conditions Does Cardiac Ablation Treat

    Survival After Coronary Artery Bypass Grafting in Patients With ...

    Cardiac ablation treats heart arrhythmias that cant be controlled with medication. Heart ablation procedures can treat all types of irregular or abnormal heart rhythms, including:

    • Atrial fibrillation : Afib is the most common reason for heart ablation. When you have Afib, the upper chambers of your heart beat irregularly. The atria quiver instead of contracting. Without strong contractions, your heart cant pump blood. When your blood doesnt move through your heart properly, it increases your risk of forming blood clots within your heart and the risk of stroke if the clot travels to your brain.
    • Atrial flutter: With this condition, the atria contract to pump blood, but they do it too quickly. Atrial flutter results in a heartbeat thats faster than normal and like Afib, increases your risk for blood clots and stroke.
    • Supraventricular tachycardia : If you have SVT, your heart still pumps blood normally. But youll experience episodes of racing heartbeats . If SVT occurs frequently or for long periods, the arrhythmia can lead to heart damage and severe symptoms.
    • Ventricular tachycardia : The ventricles are the two lower chambers of your heart. An arrhythmia in those chambers causes your heart to beat too quickly, not allowing enough time for blood to fill and pump to your body, leading to a dangerous drop in blood pressure.
