Background: Five to 10% of patients with acute myocardial infarction develop cardiogenic shock and the majority of these patients are expected to die within the first few weeks. In this study, we review our recent experience in the management of patients with cardiogenic shock complicating MI and examine the effect of early invasive revascularisation on mortality.
Methods: Thirty-six consecutive patients who developed cardiogenic shock less than 48 h after MI were retrospectively evaluated and divided into two treatment groups. One group received early invasive revascularisation (n=24) and the other group had no early invasive revascularisation, but received similar conventional intensive care medical treatment (n=12).
Results: Baseline characteristics and hemodynamic variables were similar in both groups. Apart from invasive revascularisation and the use of intra aortic balloon counterpulsation (IABP), treatment strategies did not differ between the two groups. Thirty-day mortality was 21% in the revascularised group of patients and 58% in the non-revascularised group (P<0.05).
Conclusions: Our data support previous observations suggesting that an aggressive treatment strategy including early invasive revascularisation and IABP is associated with improved short and long-term survival in patients with cardiogenic shock. Since early revascularisation appears safe with a considerable treatment benefit, this approach must be considered in patients with short shock duration early after MI.
