Invasive management of NSTEMI in patients aged ≥75 was associated with shorter hospital stay and lower 6-month mortality compared to non-invasive management, though findings should be interpreted cautiously given the retrospective design and possible selection bias.
The majority of elderly NSTEMI patients in this audit underwent invasive management.
Invasive management was associated with lower 6-month mortality compared to non-invasive management.
Invasive management was associated with a shorter hospital length of stay.
Complication and readmission rates were similar between the invasive and non-invasive management groups.
Frailty was infrequently documented using formal assessment tools in this elderly NSTEMI cohort.
The local findings were considered consistent with both ESC guidelines and the SENIOR-RITA trial results.
This research examined how older patients (aged 75 and above) with a type of heart attack called NSTEMI were treated at a hospital in Dublin, Ireland, between 2020 and 2024. The study compared patients who received an invasive approach — meaning they had procedures such as coronary angiography to examine and potentially open blocked heart arteries — with those who were managed with medications alone. Of the 50 patients studied, just over half (58%) received the invasive treatment. This research suggests that patients who received invasive treatment had shorter hospital stays and a notably lower rate of death within 6 months (14.3% vs 85.7%). However, the authors emphasize that these results must be interpreted carefully. Because this was a retrospective audit rather than a controlled trial, there is a risk of selection bias — meaning that doctors may have been more likely to choose invasive treatment for patients who were already healthier or less frail, which could explain the better outcomes in that group rather than the treatment itself being the sole reason. Notably, formal frailty assessments were rarely documented, making it difficult to fully account for this factor. The findings are particularly relevant in light of the SENIOR-RITA trial, a major recent study that found no clear mortality benefit from invasive management in older NSTEMI patients. The authors note their local results do not contradict SENIOR-RITA and that their hospital's practice aligns with European cardiology guidelines. This research highlights the ongoing complexity of treating heart attacks in elderly patients and underscores the need for better documentation of frailty and larger, well-controlled studies to guide treatment decisions in this population.
