Are Women Surgeons Better Than Men?

Posted 8 days ago by Drugs.com

TUESDAY, Oct. 10, 2017 – The gender of a surgeon appears to have little to do with the outcome of an operation. A Canadian study found that patients operated on by women had no more complications or problems after surgery than did patients whose surgeons were men. "Our findings have important implications for supporting sex equality and diversity in a traditionally male-dominated profession," the study authors wrote. The researchers, led by Dr. Raj Satkunasivam, a Houston Methodist Hospital surgeon previously at the University of Toronto, investigated whether gender plays a role in surgical skills and outcomes. The team analyzed the link between surgeons' gender and the results of 25 common surgical procedures over an eight-year span. The investigators compared the outcomes of over 104,000 procedures performed by 774 female surgeons with the outcomes of the same surgeries performed at ... Read more

Which Heart Bypass Surgery Works Best?

Posted 17 Aug 2017 by Drugs.com

THURSDAY, Aug. 17, 2017 – Five years after heart bypass surgery, patients whose operation was done using a heart-lung pump lived longer than those whose surgeons didn't use the device, a new study finds. Since the 1990s, two different approaches have been commonly used by heart surgeons to perform coronary artery bypass graft operations. Coronary artery bypass creates new routes for blood to flow to the heart because old routes are blocked by plaque in the artery. A piece of blood vessel is taken from another area of the body (often the leg) and used to "bypass" a blocked vessel going to the heart, according to the U.S. National Heart, Lung, and Blood Institute. The two different ways to do this surgery have been referred to as "on-pump," assisted by a heart-lung machine, or "off-pump." Which procedure produces better results has been controversial, the researchers said. "The ... Read more

Obesity Slows Recovery for Heart Surgery Patients: Study

Posted 10 Aug 2017 by Drugs.com

THURSDAY, Aug. 10, 2017 – Obese heart surgery patients spend more time in intensive care and take longer to recover than those who aren't obese, a new Canadian study finds. Researchers examined data from nearly 5,400 patients who had heart surgery at the New Brunswick Heart Center between January 2006 and December 2013. Of those, 36 percent were obese. After heart surgery, obese patients were four times more likely to need extra time in the ICU; three times more likely to need extra time on mechanical ventilation; and three times more likely to be readmitted to the ICU, the study showed. Obese patients also had longer overall hospital stays and were more likely to be discharged with home care. It all adds up to more labor-intensive and costly care for these patients, according to the researchers. The study was published online Aug. 10 in The Annals of Thoracic Surgery. "Obesity is a ...

Angioplasty Outcomes Almost Equal Among Hospitals

Posted 7 Aug 2017 by Drugs.com

MONDAY, Aug. 7, 2017 – Patients who have an artery-opening procedure called percutaneous coronary intervention (PCI) have similar outcomes whether they're treated at so-called safety-net or non-safety-net hospitals, researchers say. Safety-net hospitals, which provide care to low-income Americans who are uninsured or underinsured, tend to have fewer resources than other hospitals, the researchers said. In this study, at least 10 percent of patients who underwent PCI – also known as angioplasty – at safety net hospitals did not have insurance. California researchers analyzed data from 3.7 million patients who underwent PCI at 282 safety-net hospitals and 1,134 non-safety-net hospitals between 2009 and 2015. The risk of in-hospital death was only slightly higher (4 more per 1,000 PCI procedures) at safety-net hospitals than at non-safety-net hospitals. Patients treated at safety-net ... Read more

Geneticists Repair Mutation in Human Embryo

Posted 2 Aug 2017 by Drugs.com

WEDNESDAY, Aug. 2, 2017 – In a first-ever experiment, geneticists have successfully modified a human embryo to remove a mutation that causes a life-threatening heart condition. This is the first study to demonstrate that a gene-editing technique can be used in human embryos to convert mutant genes back to their normal version, the researchers said. The new procedure tackled a genetic mutation in human embryos that causes hypertrophic cardiomyopathy, an inherited condition in which the heart muscle becomes abnormally thick. The mutation was successfully repaired in 72 percent of 18 embryos that were created in a lab using sperm from a male donor who carries the hereditary heart condition, said team member Dr. Paula Amato. She is an adjunct associate professor of obstetrics and gynecology at Oregon Health & Science University (OHSU) in Portland. The procedure also might work in other ... Read more

Study Spots Cause of Global Outbreak of Infections Tied to Heart Surgeries

Posted 13 Jul 2017 by Drugs.com

THURSDAY, July 13, 2017 – Factory contamination of medical devices likely caused potentially fatal infections in 33 open-heart surgery patients in several countries, investigators say. The patients were sickened with Mycobacterium chimaera bacteria, which can cause infection of the inner lining of the heart and spread to the rest of the body. Genetic examination of M. chimaera samples suggests that heater-cooler units produced by LivaNova in a factory in Germany were the likely source of infection, according to the study. The devices help keep a patient's circulating blood and organs at a set temperature during heart bypass procedures, according to the U.S. Centers for Disease Control and Prevention. Patients became ill in the United States, Australia, Switzerland, Germany, the Netherlands, and the United Kingdom, according to the study. The results appear online July 12 in The Lancet ...

Viagra Might Make for a Safer, More Effective Stent

Posted 11 Jul 2017 by Drugs.com

MONDAY, July 10, 2017 – It's worked wonders for men battling erectile dysfunction, and now early research suggests that Viagra – when added to artery-opening stents – might cut a patient's odds for clots. Stents are tiny mesh tubes surgically inserted to prop up failing blood vessels. But as South Korean researchers explained, these devices can become less effective over time as the growth of tissue around the metal device narrows the artery again. But in their new study in rats, the researchers found that coating stents with Viagra (sildenafil) might help prevent this re-closure from happening. "If similar results are found in clinical trials, sildenafil could be an ideal drug for coating drug-eluting [emitting] stents or to give orally after stent implantation," study lead author Dr. Han-Mo Yang said in a news release from the American Heart Association. Yang is an associate ... Read more

Implantable Defibrillator May Not Mean End to Sports

Posted 5 Jun 2017 by Drugs.com

MONDAY, June 5, 2017 – Competitive sports may be safe for many athletes who have an implantable cardioverter defibrillator (ICD), new research suggests. The four-year study followed 440 athletes with ICDs who participated in vigorous sports such as running, basketball, soccer, tennis, volleyball, skiing and snowboarding. An ICD is a battery-powered device placed under the skin. When it detects an abnormal heart rhythm (arrhythmia), it delivers an electric shock to restore normal rhythm. In 2015, the American Heart Association said participating in competitive sports may be considered for athletes with ICDs. That advice was based on a study that followed hundreds of athletes with the devices for two years. This longer study of 10- to 60-year-olds followed competitive athletes at the national and international level, high school and college athletes, and others. During the study period, ... Read more

Busiest Docs Get Best Results With Heart Valve Surgery

Posted 2 May 2017 by Drugs.com

TUESDAY, May 2, 2017 – Patients who have heart valve surgery get better results and are more likely to survive if their surgeon does a lot of the operations, a new study. Researchers from Mount Sinai Health System in New York City studied New York state data on patients who had a type of heart operation called mitral valve surgery between 2002 and 2013. Damaged mitral valves can be either repaired or replaced. Mitral valve repair has several important advantages over valve replacement, including better life expectancy and quality of life, according to background information with the study. However, among heart surgeons, there is a great deal of variability over their choice of surgery, the researchers noted. In the study, those patients whose surgeons did more than 25 of the operations a year were more likely to get valve repair than replacement, and their repair was more durable than ... Read more

Blood Test May Gauge Death Risk After Surgery

Posted 25 Apr 2017 by Drugs.com

TUESDAY, April 25, 2017 – A highly sensitive blood test can identify patients with a raised risk of death in the month after surgery, a large study suggests. On average, 1 percent of patients die within 30 days after noncardiac surgery – most from a heart attack, said researcher Dr. P.J. Devereaux, a professor at McMaster University in Ontario, Canada. Testing for a protein called troponin that's found in heart muscle can help identify those post-op patients most at risk, Devereaux and an international team of researchers reported. However, the study could not prove a direct cause-and-effect relationship between troponin levels and death risk. Surgery is a major stress to the body's organs. Troponin is released into the blood when the heart muscle has been damaged, Devereaux explained. "Most of the heart injuries happen in the first day-and-a-half after surgery, when most patients are ... Read more

Pump Implants May Rejuvenate Heart Failure Patients

Posted 18 Apr 2017 by Drugs.com

TUESDAY, April 18, 2017 – Implanted pumps may be more than a "bridge" to a heart transplant – they might also restore healthy heart function for some heart failure patients, a new British study suggests. As the researchers explained, these battery-operated left ventricular assist devices (LVADs) are often used to support patients with severe heart failure while they await a heart transplant. But this new clinical trial is the first to show that an LVAD, combined with medication, can restore heart function completely, researchers said. "We talk about these devices as a bridge-to-transplant, something which can keep a patient alive until a heart is available for transplantation," said study lead author Djordje Jakovljevic. "However, we knew that sometimes patients recover to such an extent that they no longer need a heart transplant," noted Jakovljevic, a senior research fellow in ... Read more

Baseball Great Rod Carew Owes His Life to NFL Player's Transplanted Organs

Posted 17 Apr 2017 by Drugs.com

MONDAY, April 17, 2017 – When Baseball Hall of Famer Rod Carew received a new heart and kidney last December, he and his family had no idea who they had to thank for the lifesaving organs. But some good sleuthing by Carew's wife and the mother of the anonymous donor unearthed a startling discovery: The organs had come from former National Football League tight end Konrad Reuland, who was only 29 when he died after suffering a brain aneurysm. Carew, 71, needed the new organs because of a massive heart attack he had in 2015, which was followed by subsequent complications. He received the new organs in an operation performed at Cedars-Sinai Medical Center in Los Angeles. After the transplant, a number of Carew's family and friends asked Carew's wife, Rhonda, if the new organs might have come from Reuland. That prompted her to begin investigating. She learned the donor was a healthy local ... Read more

Taking Statins May Boost Heart Surgery Outcomes

Posted 16 Mar 2017 by Drugs.com

THURSDAY, March 16, 2017 – Heart surgery patients taking statins should keep taking those cholesterol-lowering drugs, even on the day of their operation, because doing so may improve their chances of survival, a new study suggests. "Based on our findings, we would advise patients to continue taking their statin medication all the way up to and including the day of surgery," said study author Dr. Wei Pan. Statins are one of the most widely prescribed drugs in the United States. One in four Americans 40 or older takes a statin, according to the U.S. Centers for Disease Control and Prevention. In the new study, Pan's team looked at more than 3,000 patients who underwent coronary artery bypass graft surgery. Pan is a cardiovascular anesthesiologist at the Texas Heart Institute in Houston. The findings showed that the rate of death from all causes within 30 days was about 2 percent for ... Read more

Stent Patients Face Higher Risk of Death After Bleeding, Clots

Posted 15 Mar 2017 by Drugs.com

WEDNESDAY, March 15, 2017 – More than a year after getting stents to prop open their clogged arteries, some patients are still at increased risk of death if they suffer either blockages or bleeding events, researchers report. The researchers added that their findings highlight the need to identify which patients are more likely to benefit from prolonged anti-clotting treatment after stenting – and which are not. "Since our analysis found that the development of both ischemic [decreased blood flow] and bleeding events portend a particularly poor overall prognosis, we conclude that we must be thoughtful when prescribing any treatment... that may include bleeding risk," said study lead author Dr. Eric Secemsky. He is a fellow at Massachusetts General Hospital's division of cardiology. For the study, the researchers tracked long-term risks among people who had ischemia or bleeding events ... Read more

Learning Issues Common in Kids With Heart Defects: Study

Posted 22 Feb 2017 by Drugs.com

TUESDAY, Feb. 21, 2017 – Children born with heart defects seem to be at increased risk of learning problems in elementary school, a new study suggests. And those with less severe heart abnormalities may not receive needed assistance, the study of third graders from North Carolina found. Among more than 9,000 students, children born with a heart defect were 24 percent more likely to not meet end-of-year standards in reading or math, compared to those with healthy hearts, the researchers determined. "Schools should be aware that children with heart defects can have learning difficulties, even many years after their heart defect is supposedly 'fixed,' " said study lead author Dr. Matthew Oster. He's a pediatric cardiologist at Children's Healthcare of Atlanta. Examining education records and birth data, the researchers compared more than 2,800 children born with heart defects – so-called ... Read more
