G. Gimelli et al., Primary versus rescue percutaneous corollary intervention in patients withacute myocardial infarction, ACT CARDIOL, 55(3), 2000, pp. 187-192
Objective - To compare angiographic and clinical outcomes of patients with
acute myocardial infarction (AMI) who underwent primary percutaneous corona
ry intervention (PCI) versus rescue PCI following failed thrombolysis.
Background - Patients presenting with AMI are treated either with primary P
CI or with thrombolysis, When thrombolysis fails, rescue PCI is performed.
Methods and Results - We compared the outcome of 105 consecutive patients w
ith AMI who underwent either primary PCI (60 patients) or rescue PCI (45 pa
tients) between January 1997 and January 1999, The patients were followed f
or up to 6 months. Time delay to reperfusion was significantly longer in th
e rescue PCI group (354 vs. 189 min; p < 0.001), The majority of patients r
eceived a stent (93%). Glycoprotein (GP) IIb/IIIa inhibitors were used in 5
3% of patients in the primary PCI group and in 22% in the rescue group. TIM
I grade 3 flow was achieved in 93.3% of patients in the primary PCI group a
nd in 88.8% in the rescue group (p = 0.08), Post-procedure ejection fractio
n was 53% in the primary PCI group and 47% in the rescue group (p = 0.014),
A composite endpoint of death, recurrent MI, repeat PCI, coronary artery b
ypass grafting (CABG) and recurrent angina at 6 months occurred in 35% of t
he patients in the primary PCI group and 26.7% in the rescue group (p = 0.3
6),
Conclusion - Despite a significant delay to reperfusion and a lower immedia
te post-procedure ejection fraction, the clinical outcome of patients treat
ed with rescue PCI following failed thrombolysis appears to be similar to t
hat of patients treated with primary PCI at 6 months.
