Key result
Patients ≥75 years with STEMI had higher 30-day mortality than younger patients (13% vs 6.4%, P=0.03), but mortality was not significantly higher after successful PCI (7.4% vs 3.9%, P=0.23).
Why the study?
Does percutaneous coronary intervention yield similar mortality outcomes in patients ≥75 years of age with STEMI compared to younger patients?
Population
504 consecutive patients who underwent angiography for acute STEMI, including 115 patients ≥75 years of age.

Successful PCI may equalize 30-day STEMI mortality in patients ≥75 years; extends observational support but leaves open randomized confirmation.

Absolute Event Rate: 13% vs 6.4%
p-value: p=0.03
Successful PCI in STEMI patients ≥75 years old yields 30-day mortality rates comparable to younger patients, highlighting the benefit of revascularization in the elderly.
Zimmermann et al. (2009) conducted a cohort in ST elevation infarction (STEMI) (n=504). Age ≥ 75 years vs. Younger patients was evaluated on 30-day mortality (p=0.03). Patients ≥75 years with STEMI had higher 30-day mortality than younger patients (13% vs 6.4%, P=0.03), but mortality was not significantly higher after successful PCI (7.4% vs 3.9%, P=0.23).
