Engineered Tissue Improves Heart Function after Heart Attack

2017 02 Feb

A proof-of-concept study, published in the journal Circulation Research, describes a novel technique for growing heart cells in a 1-micron-resolution scaffold made using a 3D printer. The mix of human cells organised themselves in the scaffold to create engineered heart tissue that beats synchronously in culture. When the human-derived heart muscle... Read more

Body Temperature Changes Trigger Sudden Cardiac Death

2015 20 Jul

According to a study published in the Journal of Physiology , sudden cardiac death caused by cardiac arrhythmia can be triggered by changes in body temperature.  Sudden cardiac death can have several causes including inheritable mutations in our DNA affecting structure and function of proteins in the heart. During the study, Simon Fraser University... Read more

3D Nano-images of Heart Cells Provide Key Heart Attack Clues

2015 09 Jun

Newly released images from researchers at The University of Manchester's Institute of Cardiovascular Sciences reveal the bicycle spoke structure of a heart cell. This could potentially hold key clues to reducing damage from a heart attack. The research, conducted by Dr. Ashraf Kitmitto and colleagues, provides new information about why some cells...

New Mathematical Model Helps Digitalise Heart Rhythms

2015 11 Mar

A new mathematical model has been developed by a team of scientists at John Hopkins led by cardiologist and biomedical engineer Hiroshi Ashikaga, M.D, PhD. The model can measure and digitally map the beat-sustaining electrical flow between heart cells. The approach has been described in the Journal of the Royal Society Interface. The team believes...
