Patients younger than 45 with ST-elevated MI (STEMI) have a higher risk of mortality after percutaneous coronary intervention (PCI) than those with non-STEMI, Victorian researchers say.

This group needs “intensive secondary prevention measures”, the team writes in the American Journal of Cardiology.

The study examined mortality rates for consecutive patients enrolled in the Melbourne Interventional Group registry of people who underwent PCI in one of six participating Victorian hospitals between 2005 and 2017.

Outcomes for the 27,869 patients were analysed by age group: 1171 young patients (aged 45 or under when they had their PCI), 12,830 middle-aged patients (46-65 years), and 13,328 older patients.
