Researchers find Cell that Replenishes Heart Muscle

2015 28 Jun

Researchers at UT Southwestern Medical Center have identified a cell that replenishes adult heart muscle by using a new cell lineage-tracing technique. The study is published online in Nature. Most cardiomyocytes don’t replenish themselves after a heart attack or other significant heart muscle damage but these researchers have identified a cell that... Read more

First 6 Months Best for Stimulating Heart Growth

2015 06 May

A Boston Children's Hospital study, published in Science Translational Medicine, shows that the first six months of life is the best time to stimulate heart muscle cell regeneration (cardiomyocyte proliferation)."Our results suggest that early administration of neuregulin may provide a targeted and multipronged approach to prevent heart failure in infants...

Long-Term Use of LVADs Induces Heart Muscle Regeneration

2015 24 Jan

Researchers at UT Southwestern Medical Center have found that long-term use of a left ventricular assist device (LVAD) by patients with heart failure may induce regeneration of heart muscle by preventing oxidative damage to a cell-regulator mechanism. Their study appears online in the Journal of the American College of Cardiology.The study looked at... Read more

Heart Muscle Inflammation Peaks Twice after MI

2014 21 Nov

A new study provides evidence challenging the current consensus in cardiology that peak myocardial oedema (heart muscle swelling) only occurs immediately after a myocardial infarction (MI) or heart attack. In the study, researchers discovered a second wave of swelling and inflammation which occurs within a week of a heart attack.The discovery of this... Read more

'Heart Disease-on-a-Chip' Modelled From Patient Stem Cells

2014 14 May

By merging stem cell and 'organ-on-a-chip' technologies Harvard scientists have, in a world premiere, successfully grown functioning human heart tissue that carries an inherited cardiovascular disease.A major development for personalised medicine, this research, which was published in Nature Medicine, provides working proof that laboratory-based replication...

Cardiac Hypertrophy: Preventable via Protein

2014 13 May

As cardiovascular disease remains the Western world’s leading cause of death, heart failure is the category registering the fastest incidence increase over the past ten years.Pathological hypertrophy, defined as the heart muscle’s growth as its attempt to increase its output, is the stage that precedes heart failure, yet not all hypertrophy is pathological....
