Abstract
Background: Among patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary
intervention (PCI), those with multivessel disease have worse prognosis, mainly due to a higher frequency of cardiogenic shock (CS) at
admission. The aim of this study was to identify clinical and angiographic characteristics of patients with STEMI, multivessel disease and CS
at admission referred to primary PCI.
Methods: We studied 630 patients with STEMI treated with primary PCI within 12 h after symptoms onset. Multivessel disease was defined
as the presence of ≥ 50% stenosis in ≥ 2 major epicardial arteries. Multivessel disease was documented in 276 patients (44%), these patients
comprising the study population. Clinical, angiographic and procedural variables were compared between those with and without CS. A
logistic regression analysis was performed to identify the independent predictors of CS among patients with multivessel disease.
Results: Among patients with multivessel disease, 45 (16%) had CS at admission. The independent predictors of CS in patients with
multivessel disease were: STEMI anterior [OR 2.05; 95% CI 1.0 to 4.1; p = 0.044], female gender [odds ratio (OR) 2.49; 95% confidence
intervals (CI) 1.1 to 5.3; p = 0.021], proximal culprit lesion [OR 3.8; 95% CI 1.7 to 8.5; p b 0.001], and chronic occlusion of other coronary
arteries [OR 4.48; 95% CI 2.1 to 9.1; p b 0.001].
Conclusions: Among patients with STEMI and multivessel disease, CS is especially frequent in STEMI anterior, female gender, proximal
culprit lesion, and chronic occlusion of other vessels.

1. Introduction
Cardiogenic shock (CS) is a serious complication and the
leading cause of in-hospital mortality in patients with ST-
segment elevation myocardial infarction (STEMI). It affects
approximately to 7–10% of patients with STEMI, and occurs
mainly within the 48 h after symptoms onset [1,2]. In these
patients, a strategy of early revascularization is associated with
better outcomes than intensive medical therapy [3–5], but
mortality rate remains very high (N 50%) [6–8].
Multivessel disease is present in 40–60% of patients with
STEMI referred to primary percutaneous coronary interven-
tion (PCI). These patients have worse prognosis, with a
worse clinical outcome mainly due to a higher frequency of
CS at admission [9–12]. The aim of this study was to identify
