Patients aged ≥ 80 years with ST–elevation myocardial infarction (STEMI) are often underrepresented in major percutaneous coronary intervention (PCI) trials. The proportion of patients aged ≥ 80 years receiving PCI for STEMI and their outcomes over the past 10 years needed investigation.
We examined the temporal trends (2001–2010) in STEMI, use of PCI for STEMI and outcomes (average length of stay and in–hospital mortality) among patients aged ≥ 80 years in the United States using the Nationwide Inpatient Sample (NIS) database.
During 2001–2010, among 1,704,385 patients aged ≥ 80 years admitted for acute myocardial infarction, 570,824 (33.5%) had STEMI. There was a 19% decrease (Ptrend <0.001) in the prevalence of STEMI among these patients over the 10–year period. The proportion of patients aged ≥ 80 years undergoing PCI for STEMI increased from 9.2% in 2001 to 31.2% in 2010 (Ptrend <0.001). Among these patients, a significant decrease in the average length of stay (5.6 ± 5.5 days in 2001 versus 4.9 ± 4.6 days in 2010; Ptrend <0.001) and in–hospital mortality (age–adjusted mortality rate per 1,000 of 150 in 2001 versus 116 in 2010; Ptrend =0.020) was observed.
Although the percentage of patients aged ≥ 80 years presenting with STEMI has decreased during the past decade, the percentage of patients receiving PCI for STEMI has increased. This is also associated with a decrease in the duration of hospitalization and in–hospital mortality over the past 10 years.
