Primary versus facilitated percutaneous coronary intervention in acute myocardial infarction complicated by cardiogenic shock
Folia Cardiol 2006;13(5):384-389.
Abstract
Background: Mortality in patients with cardiogenic shock (CS) due to acute myocardial
infarction (MI) may be decreased by fibrynolytic therapy combined with intraaortic balloon
counterpulsation or by invasive treatment, either with percutaneous coronary intervention (PCI)
or coronary artery bypass grafting (CABG). The aim of the study was to compare in-hospital
and long-term outcomes in patients with acute MI complicated by CS who were treated with
primary or facilitated PCI.
Methods: Among 98 consecutive patients with acute MI complicated by CS, 93 patients were treated with PCI and 5 patients underwent CABG. Patients treated with PCI were divided into two groups: group I included 59 patients treated with facilitated PCI and group II included 34 patients treated with primary PCI. Patients in group II were older, had higher systolic and diastolic blood pressure, and more often presented with 1-vessel disease and previous MI, while 3-vessel disease was more common in group I (all p < 0.05).
Results: Immediate PCI success rate was similar in both groups (83% in group I vs. 74% in group II, p = NS), as was in-hospital mortality (41% vs. 36%, respectively, p = NS) and mortality rate in the cardiac cathetherization laboratory (20% vs. 15%, respectively, p = NS). The need for repeated PCI was significantly more common in group I (22% vs. 3%, p = 0.02). The two groups did not differ with respect to the need for CABG or the rate of hemorrhagic complications. During one year follow-up, three deaths occurred in every group, including two patients in each group who died suddenly.
Conclusions: Comparable immediate PCI success rate, in-hospital mortality, and long-term mortality were seen in patients with acute MI complicated by CS treated with primary or facilitated PCI. More coronary reinterventions were needed in patients treated with facilitated PCI compared to those treated with primary PCI.
