The CRISP AMI trial

The CRISP AMI trial found that intra-aortic balloon counterpulsation does not reduce infarct size in patients with ST segment elevation myocardial infarction (STEMI) without cardiac shock. The study showed no significant difference in infarct size between the groups, but IABC was associated with lower mortality rates.

Discovery in cardiology: A medication reduces heart volume

A new medication, ivabradine, has been shown to reduce both heart rate and volume in patients with cardiac insufficiency, leading to a significant reduction in mortality and hospitalizations. This discovery holds promise for a new approach to treating this condition.

Marathons damage the hearts of less fit runners for up to 3 months

A new study from the Heart and Stroke Foundation of Canada found that marathon runners who are not adequately prepared can experience heart damage due to inadequate aerobic fitness. The study used MRI measurements to determine who is at risk of cardiac injury, highlighting the importance of proper training and cardiovascular testing.
