A study from UT Southwestern researchers found that recently introduced cholesterol guidelines would significantly reduce new cardiovascular events, when compared to treatment based on previous cholesterol guidelines. The research identified Dallas Heart Study participants in the 30 to 65 age range who would have newly qualified for statin use under the new cholesterol guidelines introduced in 2013 by the American College of Cardiology (ACC) and the American Heart Association (AHA).

It is widely accepted that heart muscle cells in mammals stop replicating shortly after birth, limiting the ability of the heart to repair itself after injury. A study published by Cell Press May 8th in the journal Cell now shows that heart muscle cells in mice undergo a brief proliferative burst prior to adolescence, increasing in number by about 40% to allow the heart to meet the increased circulatory needs of the body during a period of rapid growth. The findings suggest that thyroid hormone therapy could stimulate this process and enhance the heart's ability to regenerate in patients with heart disease.

It’s about the size of a large vitamin pill and, for the first time in Ohio, the smallest heart pacemaker available is being tested at The Ohio State University Wexner Medical Center. Doctors at Ohio State’s Richard M. Ross Heart Hospital recently implanted the tiny device in a Columbus woman as part of a global clinical trial to test its safety and effectiveness.  Unlike conventional pacemakers, which require a chest incision and electrical leads that run through a vein to the heart, this device is wireless and is threaded through a catheter, then attached directly to the heart muscle.

Numerous studies have suggested a relationship between cardiovascular disease risk factors and prostate cancer. A new study by researchers at the University of California, San Diego School of Medicine, with colleagues in Norway, significantly refines the association, highlighting genetic risk factors associated with low density lipoprotein (LDL) cholesterol and triglycerides as key players and identifying 17 related gene loci that make risk contributions to levels of these blood lipids and to prostate cancer.

Scientific research at UT Southwestern Medical Center previously discovered that the newborn animal heart can heal itself completely, whereas the adult heart lacks this ability. New research by the same team today has revealed why the heart loses its incredible regenerative capability in adulthood, and the answer is quite simple – oxygen.

Motor neuron disease or central nervous system injury can lead to loss of essential voluntary muscle activity such as speaking, walking, breathing, and swallowing due to defects in motor neurons. A new study published on 4th April in the journal Science describes a method for bypassing the defective central motor circuit using engrafted, light-activated motor neurons. The study in mice was led by researchers in University College London (UCL) and King’s College London and offers hope for treatment of paralysis and breathing difficulties in these devastating conditions.
