Improved treatment and management of acute myocardial infarction have led to significant reductions in 30-day mortality, from 12.9% to 3.9%, and in-hospital complications. The analysis suggests that the declines are due to both increased use of recommended interventions and earlier use of medications.
A new algorithm using high-sensitivity cardiac troponin T values can quickly classify patients as either likely to have a heart attack or not, reducing the need for prolonged monitoring.

A study found that US patients treated for acute heart attacks were more likely to be readmitted within 30 days due to shorter hospital stays. This may be attributed to the US healthcare system's episodic care approach, which can lead to inadequate management of patients after discharge.
A new study conducted by Duke University Medical Center researchers found that inserting intra-aortic balloon pumps prior to angioplasty in patients with acute myocardial infarction does not reduce the scope of heart muscle damage, also known as infarct size. The study's findings were published online and presented at the European Soci...
Acute myocardial infarction (AMI) is a leading cause of death in the Western world, with prevalence expected to rise in developing countries. Primary PCI can open more vessels than thrombolytic therapy, saving more lives but requiring specialized facilities and collaboration.
