Biomedical engineers grow cardiac patches to help people recover from heart attacks A little goes a long way. Tiny blood vessels are essential for regenerative engineering and a team led by engineers has detailed innovative methods to ensure highly aligned, dense and mature microvasculature in engineered tissue that can be used for cardiac patches.

Computer program predicts risk of deadly irregular heart beats Combining a wealth of information derived from previous studies with data from more than 500 patients, an international team led by researchers has developed a computer-based set of rules that more accurately predicts when patients with a rare heart condition might benefit — or not — from lifesaving implanted defibrillators.
