Analysis of four French registries from 1995 to 2010 shows significant improvements in management and outcomes for acute myocardial infarction (AMI) patients, resulting in a notable decrease in 30-day mortality rates. This improvement is attributed to increased use of coronary angiography/PCI and early adoption of recommended medications.
