Background There are conflicting data about the efficacy of aggressive trea
tment and early intervention among highrisk patients with acute myocardial
infarction (AMI), such as elderly patients. This study sought to determine
the short- and long-term outcome of octogenarian and older patients after p
rimary percutaneous transluminal coronary angioplasty (PTCA).
Methods In our tertiary referral center a program of primary PTCA was begun
in 1995, and the systematic care for AMI included primary PTCA in all pati
ents with AMI, with no age restriction. Over a period of 3 years, 55 octoge
narian or older patients underwent primary PTCA.
Results Between January 1995 and July 1998, 719 patients with AMI underwent
primary PTCA. OF these, 55 patients were octogenarians or order (mean age,
84 +/- 3 years). Primary PTCA failure occurred in 3 (5%) patients. An opti
mal acute angiographic result was achieved in 51 (93%) patients. Stenting o
f the infarct vessel was accomplished in 33 (60%) patients. The 30-day mort
ality rate was 16%. The mortality rate was 4% in patients without cardiogen
ic shock on presentation and 70% in patients with cardiogenic shock. The re
current ischemia rate was 13% and resulted in nonfatal reinfarction in 2 pa
tients and repeat PTCA in 5 patients. As determined by multivariate analysi
s, an optimal acute angiographic result and cardiogenic shock were signific
antly related to mortality. The 1-year survival rate was 77%.
Conclusions The results of this study suggest that the benefits of primary
PTCA apply to the very elderly and support on early aggressive strategy for
this high-risk patient subset.
