(Press-News.org) Chicago, March 17, 2015 - Patients with severe mitral regurgitation (MR) often suffer from psycho-emotional symptoms, such as depression and anxiety, but after undergoing mitral valve repair surgery patients experience a marked improvement in emotional and physical wellbeing, according to an article in the March 2015 issue of The Annals of Thoracic Surgery.
Key points
Patients with severe mitral regurgitation, who had suffered from anxiety and post-traumatic stress symptoms prior to mitral valve surgery, experienced a marked improvement in emotional and physical wellbeing by 6-months after surgery.
No improvement was shown in patients with mitral regurgitation and psycho-emotional issues who did not undergo surgery.
The type of mitral valve surgery (standard vs minimally invasive) did not make a difference in psycho-emotional improvement.
Previous research has shown that one in four patients with severe MR (caused when the heart's mitral valve doesn't close tightly, allowing blood to flow backward into the heart) suffer from poor psycho-emotional status (PES), elevated anxiety, and traumatic stress levels. Other challenging symptoms, such as dyspnea (shortness of breath or breathlessness) and fatigue also have been found in patients with poor PES.
Maurice Enriquez-Sarano, MD, from the Mayo Clinic in Rochester, Minn., and Tali Bayer-Topilsky, PhD, from JDC-Myers-Brookdale Institution in Jerusalem, Israel, led a questionnaire-based analysis to assess PES and health-related quality of life in 131 patients before and 6-months after surgery for MR. Results were compared to 62 patients with MR who did not undergo surgery and to 36 control patients.
In this study, PES was defined by the levels of a patient's emotional distress (depression and anxiety) and by traumatic-stress-related symptoms.
Preoperative questionnaire results showed that PES was poorer among patients who ultimately underwent valve repair surgery, compared with the other two groups. Health-related quality of life showed similar baseline results.
"Interestingly, at the 6-month follow-up examination, psycho-emotional symptoms and quality-of-life measurements in patients who underwent mitral valve correction improved and normalized to levels observed in controls; however, there was no improvement of these symptoms in MR patients who were not referred to surgery," said Dr. Bayer-Topilsky. "Another important finding of our study relates to 'asymptomatic' MR patients, who did not experience any physical symptoms-- like shortness of breath or fatigue--prior to the surgery, yet suffered from elevated psycho-emotional symptoms. Asymptomatic patients indeed improved after the surgical correction, thus exhibiting a better and normalized psycho-emotional status."
Additional results showed that the type of MR repair surgery (standard vs minimally invasive) did not make a difference in patient PES improvement.
"Early surgery in patients without symptoms or left ventricular dysfunction has been previously considered as providing no direct patient benefit, but our study results show how wrong this concept is," said Dr. Enriquez-Sarano. "Patients with a serious valve disease often suffer from the psychological consequences of leaving that disease untreated. Eliminating the valve disease reduces this suffering, further supporting the concept of early MR repair."
Surgical Repair in Asymptomatic Patients
In an invited commentary in the same issue of The Annals, Daniel J. Ullyot, MD, from the University of California in San Francisco, noted the inherent conflict of early surgical intervention among asymptomatic patients, "The admonition 'do no harm' councils restraint, especially in asymptomatic patients for whom the clinical benefit may be far in the future."
However, he said that the survey findings are important and require more investigation, "We need to know if improved mental health is sustained beyond 6 months after surgery, and if the favorable impact of surgery is the result of restoring normal valve function or some other effect of surgical intervention."

Cod liver oil and willow bark extract used in the tanning of skins for clothing and other products offer notable differences in treatment, a study by a team of scientists shows. Their findings show the promise of a technique that may be used to identify the aging behavior of materials and to examine delicate works of art.
The research, which appears in the journal Analytical Chemistry, relies on a method employing nuclear magnetic resonance spectroscopy, or NMR spectroscopy, which reveals the physical and chemical properties of atoms in a given substance, as well as the ...
A research team led by Northwestern University nanomedicine expert Chad A. Mirkin and Sergei Gryaznov of AuraSense Therapeutics is the first to show spherical nucleic acids (SNAs) can be used as potent drugs to effectively train the immune system to fight disease, by either boosting or dampening the immune response. The initial treatment triggers a cell-specific immune response all over the body.
By increasing the body's immune response toward a specific cell type, SNAs could be used to target anything from influenza to different forms of cancer. They also can be used ...
New heart imaging technology to diagnose coronary heart disease and other heart disorders is significantly more accurate, less expensive and safer than traditional methods, according to a new study by researchers from the Intermountain Medical Center Heart Institute in Salt Lake City.
Researchers at the Intermountain Medical Center Heart Institute compared Single Photon Emission Computed Tomography (SPECT), currently the most commonly used imaging diagnostic tool, with a new imaging technology -- coronary-specific Positron Emission Tomography (cardiac PET/CT).

A recently published global genome study that used the data-intensive Gordon supercomputer at the San Diego Supercomputer at the University of California, San Diego, has researchers rethinking how avian lineages diverged after the extinction of the dinosaurs.
The four-year project, called the Avian Genome Consortium and published in the journal Science, resulted in a new family "tree" for nearly all of the 10,000 species of birds alive today by comparing the entire DNA codes (genomes) of 48 species as varied as parrot, penguin, downy woodpecker, and Anna's hummingbird. ...
SAN DIEGO (March 16, 2015) -- Patients who experience the deadliest form of heart attack--ST segment elevation myocardial infarction (STEMI)--and suffer from substantial narrowing in multiple heart arteries may benefit from receiving angioplasty in constricted arteries not affected by the heart attack, thereby reducing the need for future angioplasty, according to research presented at the American College of Cardiology's 64th Annual Scientific Session.
The study is the largest prospective, controlled trial to evaluate whether patients should receive preventive angioplasty, ...
OAKLAND, Calif. -- Specific system-level factors controlled by health care systems - including prescriptions with a medication supply greater than 90 days, mail-order pharmacy use, and lower copayments and out-of-pocket maximums - nearly doubled the likelihood that patients adhered to prescribed heart and diabetes medications, according to a new study published in the journal Medical Care.
"This study is the first to look at all four of these system-level factors at once in the senior population," said Julie A. Schmittdiel, PhD, research scientist with the Kaiser Permanente ...
If you're a fan of food television, it's fine to be entertained by the programming, but if you take recipes for the rich meals the networks favor into your own kitchen, you're at risk of putting on pounds, according to a study just published online by the journal Appetite.
"The message is clear," said Lizzy Pope of the University of Vermont, the study's lead author. "Food TV should be a viewing experience only, not a cooking experience."
The study asked 501 women, aged 20 to 35, where they obtained information about new foods, how frequently they cooked from scratch, ...
Healthy bone is continuously involved in a dynamic process that includes bone deposition and bone resorption. However, when a person has cancer that spreads to the bone and bone marrow, the tissue becomes increasingly fragile, and this process is disrupted, usually leading to increased bone resorption.
In an early online edition in advance of publication in the International Journal of Cancer, investigators at Children's Hospital Los Angeles reported a surprising discovery - when neuroblastoma (NB) cells metastasize to the bone, there initially occurs an increase in bone ...
Berkeley -- Engineers at the University of California, Berkeley, are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers, in collaboration with colleagues at UC San Francisco, have created a new "smart bandage" that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes - and while recovery is still possible.
"We set out to create a type of bandage that could detect bedsores as ...
UNSW Australia scientists have developed a highly efficient oxygen-producing electrode for splitting water that has the potential to be scaled up for industrial production of the clean energy fuel, hydrogen. The new technology is based on an inexpensive, specially coated foam material that lets the bubbles of oxygen escape quickly.
"Our electrode is the most efficient oxygen-producing electrode in alkaline electrolytes reported to date, to the best of our knowledge," says Associate Professor Chuan Zhao, of the UNSW School of Chemistry.
"It is inexpensive, sturdy and simple ...
