Giving injections of an anticoagulant directly into the heart instead of infusing intravenously appears to boost short term survival among patients suffering a severe type of heart attack.

A study has confirmed that faster treatment for severe heart attack patients results in better clinical outcomes.

A type of inhaled asthma medication appears to slightly increase the risk that children or young adults will develop a potentially deadly heart arrhythmia.
