American Heart Association says Endothelial Cells may contribute to formation of new vessels compensating for inadequate Blood Supply

 

Circulation Research Journal Report

American Heart AssociationDallas, TX – Cells that line the interior surface of blood vessels (endothelial cells) have the capacity to clonally expand and contribute to the development of new vessels due to inadequate blood supply to the heart, known as ischemia, according to a study in mice published in Circulation Research, an American Heart Association journal.

American Heart Association says Neighborhood factors may predict Heart Failure

 

Cardiovascular Quality and Outcomes Journal Report

American Heart AssociationDallas, TX – Neighborhood-level socioeconomic factors in low-income areas may significantly predict heart failure risk beyond individual health factors and socioeconomic status, according to new research in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.

The study compared census tract data on socioeconomic deprivation – a clustering of neighborhood-level variables of wealth, education, occupation and housing patterns – and heart failure rates among 27,078 middle-aged whites and African-Americans from the Southeastern states.

American Heart Association reports Multi-Gene Test predicts early Heart Disease Risk

 

Circulation: Genomic and Precision Medicine Journal Report

American Heart AssociationDallas, TX – A risk score based on multiple genetic differences, or polygenic risk score, predicted significantly more cases of early-onset heart disease than standard tests for single genetic defects, according to new research in the American Heart Association’s journal Circulation: Genomic and Precision Medicine.

“Our results provide convincing evidence that the polygenic risk score could be added to the genetic investigation of patients with very early coronary artery disease,” said study lead author.

The polygenic test predicted a high risk for early-onset heart disease in 1 out of 53 individuals, compared to 1 in 256 for the most frequent single genetic defect. (American Heart Association)

American Heart Association says Middle-Aged Couch Potatoes may reverse Heart Effects of a Sedentary Life with Exercise Training

 

Circulation Journal Report

American Heart AssociationDallas, TX – Middle-aged couch potatoes may reduce or reverse the risk of heart failure associated with years of sitting if they participate in two years of regular aerobic exercise training, according to a new study in the American Heart Association’s journal Circulation.

Study participants who adhered to the aerobic exercise regimen had significant improvements in how their body used oxygen and had decreased cardiac stiffness after two years, both markers of a healthier heart.

Two years of exercise training during middle age may reduce or reverse the cardiac consequences of a sedentary lifestyle.

Nashville Predators Fall To Dallas Stars In Shoot-Out 4-3

 

Nashville PredatorsClarksville, TN – The Nashville Predators had every opportunity to beat the Dallas Stars Saturday night at the American Airlines Center, but couldn’t close the deal during a five on three overtime power play, falling 4-3 in a shoot-out.

Nashville took an early 2-0 lead in the contest when Alexel Emelin opened the scoring just 34 seconds into the game with a bullet from the point to put the Predators on the board first. 

Calle Jarnkrok then laced one top shelf over Ben Bishop, with the Predators short-handed, to make it 2-0, and Nashville was off to the races.

American Heart Association reports Mental Stress-Induced constricted blood vessels more likely in Women

 

American Heart AssociationDallas, TX – In women with heart disease, constriction of peripheral vessels during mental stress affects the heart circulation more than men’s, potentially raising women’s risk of heart-related events and death, according to new research in Arteriosclerosis, Thrombosis and Vascular Biology, an American Heart Association journal.

In most people, mental stress causes peripheral vessels to constrict. In people with heart disease, this effect can cause a reduction in blood supply to the heart muscle called “ischemia.”

American Heart Association reports Unmarried Heart Patients face higher risk of Death

 

Journal of the American Heart Association Report

American Heart AssociationDallas, TX – Compared to married heart disease patients, being unmarried was associated with a higher risk of dying, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

This is the first study to show an association between marital status and death from any cause and heart disease-related death in a high-risk heart patient population. (American Heart Association)

American Heart Association says Abuse and Adversity in Childhood linked to more Cardiovascular Risk in Adulthood

 

American Heart Association Scientific Statement

American Heart AssociationDallas, TX – Children and teens who are abused, witness violence, are bullied or face other adversities are more likely to develop cardiovascular diseases in adulthood, according to a new scientific statement by the American Heart Association published in the Association’s journal Circulation.

The statement is based on a review of existing scientific research published in peer-reviewed medical journals that documents a strong association between adverse experiences in childhood and teen years and a greater likelihood of developing risk factors such as obesity, high blood pressure and type 2 diabetes earlier than those not experiencing adverse experiences.

American Heart Association reports More Cardiac Arrest Victims could Survive with Dispatcher CPR Instruction, Rescue Breaths for Children

 

American Heart Association Moves to Annual Guidelines Update, a First for the Organization

American Heart AssociationDallas, TX – More people will survive cardiac arrest if emergency medical dispatchers give chest compression-only CPR instructions over the phone and if infants and children receive chest compressions with rescue breaths, according to updated CPR guidelines published today by the American Heart Association (Association), the world’s leading voluntary health organization devoted to fighting cardiovascular disease.

The changes in the 2017 American Heart Association Focused Updates on Adult and Pediatric Basic Life Support and Cardiopulmonary Resuscitation Quality also re-emphasize the importance of bystanders starting immediate chest compressions if they see an adult collapse in a suspected cardiac arrest.

More Physical Activity and Higher Intensity Physical Activity may significantly reduce Risk of Death in Older Women in the short term

 

Circulation Journal Report

American Heart AssociationDallas, TX – More physical activity and at higher intensities could lead to a big drop in the risk of death in older women from any cause, according to new research in the American Heart Association’s journal Circulation.

Researchers found the volume of light intensity physical activity or sedentary behavior was not associated with death rate. However, light intensity activity may be beneficial for other health outcomes not studied in this research.
