Heart failure: New drug could halt disease and improve heart function

-
Heart failure occurs when the heart loses its ability to pump blood effectively. Current treatments can slow or stop the disease getting worse, but they can't regress it. Now, scientists have designed a molecule that could not only curb heart failure but also improve the heart's blood pumping ability.

 The researchers in Brazil and the United States who developed and tested the experimental drug have named it "SAMβA," which is short for "selective antagonist of mitofusin 1-β2PKC association."

When the researchers gave it to rats with heart failure, the molecule not only stopped the disease from progressing but also reduced its severity by improving the ability of heart muscle to contract.

The Truth About Dealing With Heart Failure

-
A guide to reducing risks and living well even if you develop the condition Congestive heart failure is a serious illness. But it does not, as is sometimes thought, mean the heart stops ­altogether. It signifies that the muscle is damaged and can no longer pump enough blood to meet the body’s needs. This condition, which ­affects 1 in 5 adults—usually in the later years—can shorten life. But with proper treatment, people are living longer and better with heart failure. “We have more medications at our disposal today to improve quality of life for people with a weakened heart,” says Guy L. Mintz, M.D., director of cardiovascular health and lipidology at Sandra Atlas Bass Heart Hospital in Manhasset, N.Y. Here’s what to do. Coronary artery disease and heart attacks are major causes of heart failure, says cardiologist Tamara Horwich, M.D., medical director of UCLA’s cardiac rehabilitation program in Los Angeles. Managing your risk for problems—such as hig...

Breaking Down Barriers in the Fight Against Congenital Heart Disease

-
Academic research has long been characterized by silos and protective instincts. A new crop of fresh-thinking physician scientists are turning that model on its head, and the results are saving little hearts. More than 1 in every 110 babies is born with some form of congenital heart disease. CHDs are the most common birth defect, in fact. Clinicians have made great strides in improving care for these children, and even individuals with severe diseases may now live well into adulthood. However, not all survive and many still experience significant complications.   “As a doctor in a pediatric cardiac ICU, we know there are things we want to do better,” says Michael Gaies, M.D., a cardiac intensivist and director of quality at the Congenital Heart Center at Michigan Medicine’s C.S. Mott Children’s Hospital. “We believe we can improve care for kids recovering from heart surgery if we can better control certain parts of the post-operative journey.” The problem...

Cerebrovascular Disease: A Serious Complication After Allogeneic Hematopoietic Stem Cell Transplantation

-
A study published in the  International Journal of Hematology  found that the incidence of cerebrovascular disease (CVD) was approximately 10 times higher in patients after  allogeneic hematopoietic stem cell transplantation (HSCT) compared with the general Taiwanese population. Moreover, CVD was associated with the number of high-dose cytarabine courses given. The researchers retrospectively evaluated clinical data from adult patients who underwent HSCT at an Asian tertiary medical center between January 2003 and December 2015. The study aimed to estimate CVD incidence, identify associated host-related and transplant procedure-related risk factors, and measure clinical outcomes (overall survival [OS] and disease-free survival [DFS]). Data from 459 adult allogeneic HSCT recipients were assessed. Of this patient cohort, 4.4% (20/459) developed post-transplant CVD, 2.4% (11/459) had intracranial hemorrhage (ICH), and 2.2% (10/459) had cerebrovascular infarction. Media...
