Leading cardiovascular societies release new guidance on use of heart pumps

Expert consensus statement addresses expanding options for percutaneous mechanical support devices

2015-04-07
(Press-News.org) Washington, DC (April 7, 2015) - Greater availability of percutaneous mechanical circulatory support (MCS) devices for treatment of heart failure is helping expand treatment options for a rapidly growing number of acutely and chronically ill cardiac patients who could benefit from the devices. An expert consensus statement released today by the Society for Cardiovascular Angiography and Interventions (SCAI), American College of Cardiology (ACC), Heart Failure Society of America (HFSA) and The Society of Thoracic Surgeons (STS) provides new guidance to help physicians match the right device with the right patient. The statement has been endorsed by the American Heart Association (AHA), Cardiological Society of India (CSI) and the Latin American Society of Interventional Cardiology (SOLACI). The Canadian Association of Interventional Cardiology (CAIC) has affirmed the value of the statement.

"Percutaneous mechanical circulatory support is revolutionizing the treatment of high-risk cardiac patients," said Charanjit S. Rihal, MD, FSCAI, FACC, chair of the Division of Cardiovascular Diseases at the Mayo Clinic, Rochester, Minn., and lead author of the paper. "In certain patients, these devices can mean the difference between recovery and the need for heart transplant or death, and they may be used to maintain hemodynamic stability during interventional procedures and as a bridge to longer-term treatment. The new consensus statement will help physicians select devices for the patients who are most likely to benefit."

To develop the new recommendations, a panel of experts reviewed scientific data on all of the available devices, including intraaortic balloon pumps (IABP), left atrial to aorta assist devices (TandemHeart), left ventricle to aorta assist devices (Impella), extracorporeal membrane oxygenation (ECMO) as well as methods for right-sided heart support. The expert panel also reviewed indications for percutaneous MCS, including complications of heart attack, high-risk angioplasty and stenting (also known as percutaneous coronary intervention, or PCI), and advanced heart failure and cardiogenic shock.

Based on the available data and anticipated benefits and risks, the panel determined percutaneous MCS provides superior circulatory support compared to medical therapy, especially when using left ventricular assist devices. Early placement of MCS can benefit patients in cardiogenic shock when initial interventions fail to stabilize the patient. MCS may also benefit high-risk PCI patients and certain patients with acute decompensated heart failure whose symptoms are worsening despite treatment. MCS may also be used in patients who failed to wean off a heart-lung bypass machine. The evidence does not support routine use of MCS in heart attack patients.

"MCS utilization is clearly increasing, and this document should assist clinicians in recognizing when early support is needed, and what that support should look like," said Srihari S. Naidu, MD, FSCAI, FACC, FAHA, director of the cardiac cath lab at Winthrop University Hospital and vice chair of the consensus document's writing committee.

The expert consensus statement also highlights emerging treatment opportunities, such as for patients undergoing percutaneous valve replacement who have severe, non-operable valve disease, and some patients undergoing electrophysiological procedures. Currently, most percutaneous MCS devices cannot be used in children due to size limitations, but the authors note this is an important area for future development. Registries and randomized controlled trials are also critically needed to compare different devices and treatment strategies across patient populations.

Only a limited number of surveillance drug-resistance mutations (SDRMs) are responsible for most instances of non-nucleoside reverse transcriptase inhibitor (NNRTI)- and nucleoside reverse transcriptase inhibitor (NRTI)-associated resistance, and most strains of HIV-1 transmitted drug resistance (TDR) in sub-Saharan Africa (SSA) and south/southeast Asia (SSEA) arose independently, according to a study published this week in PLOS Medicine. The study, led by Soo-Yon Rhee of Stanford University, and colleagues, came to these conclusions after analyzing individual virus sequences ...

Mortality and blood pressure directly linked to relationship quality

2015-04-07
While other studies have shown that stress and negative marital quality can influence mortality and blood pressure, there has not been research that discussed how it might affect married couples over time. Using systolic blood pressure as a gauge, researchers assessed whether an individual's blood pressure is influenced by their own as well as their partner's reports of chronic stress and whether there are gender differences in these patterns. The Journals of Gerontology, Series B®: Psychological Sciences published these findings in the article titled, "Stress and ...

Common birds bring economic vitality to cities, new study finds

2015-04-07
Is it worth having birds in the city? If you live in Seattle or Berlin, the answer is yes, to the tune of $120 million and $70 million a year for each city, respectively. A new study published last month in the journal Urban Ecosystems tries to determine what economic value residents in two comparable cities place on having birds in their backyards and parks. Researchers at the University of Washington and Humboldt State University compared two types of common birds - finches and corvids - in both cities, asking residents how much they would pay to conserve the species ...

Why daring to compare online prices pays off offline

2015-04-07
This news release is available in French. The sudden closures of big-box stores like Future Shop and Target may make it seem like online shopping is killing real-world stores. But shoppers are actually engaging in "web-to-store" shopping -- buying offline after comparing prices online. New research from Concordia University's John Molson School of Business shows this consumer behaviour has important implications for retailers. When setting in-store prices or offering price-matching guarantees, offline retailers should focus more on online retailer ratings than on ...

Subtle discrimination is easier to acknowledge when self-esteem is high

2015-04-07
BUFFALO, N.Y. - Identifying discrimination is a necessary first step toward confronting and ultimately eliminating the stain of prejudice, yet victims may be unlikely to recognize some types of discrimination unless they have higher self-esteem, according to the results of a new study by two University at Buffalo psychologists. The study's results highlight the density of the discrimination target's burden, faced first with bigotry and then with the onus of pointing out that behavior. Attributing personal fate to another person's prejudice, however, is not easy and significant ...

2015-04-07
NEW YORK, NY (April 6, 2015) --A cellular defect that can impair the body's ability to handle high glucose levels and could point the way to a potential new treatment for diabetes has been identified by Columbia University Medical Center (CUMC) researchers. The CUMC team found that ryanodine receptor type 2 (RyR2) calcium channels in insulin-producing cells play an important and previously underappreciated role in glucose balance. RyR2 channels control intracellular calcium release. When leaky, they were found to reduce insulin release from the pancreas, resulting in ...

Stroke classification system called TOAST is easy to use and effective

2015-04-07
MAYWOOD, IL - In 1993, neurologists Harold P. Adams Jr., MD, and Jose Biller, MD, and colleagues proposed a new way to classify strokes. It became known as the TOAST classification. Twenty-two years later, the TOAST classification remains an effective and easy-to-use system that is routinely employed in stroke studies around the world, Drs. Adams and Biller report in the journal Stroke, published online ahead of print. Dr. Adams is a professor of neurology and director of Cerebrovascular Disease at the University of Iowa Carver College of Medicine. Dr. Biller is chair ...

Obesity in children: Breastfeeding is best, but...

2015-04-07
Yes, while breastfeeding is the optimal first food for a baby, it's not as simple to say that it will protect all children from becoming obese. Recent studies show that factors such as whether a child's mother is obese, the quality of her milk and the socio-economic conditions a baby is born into also have an influence. This is according to Jessica Woo and Lisa Martin of the Cincinnati Children's Hospital Medical Center in the US, who reviewed relevant breastfeeding studies in Springer's journal Current Obesity Reports. Because it is notoriously difficult to treat obesity, ...

Tunneling across a tiny gap

2015-04-07
Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea on a hot stove, while thermal radiation describes heat flow across large distances, such as heat emitted by the sun. These two fundamental heat-transfer processes explain how energy moves across microscopic and macroscopic distances. But it's been difficult for researchers to ascertain how heat flows across intermediate gaps. Now researchers at MIT, the University ...

UM study finds fast food just as effective for recovery as sports supplements
