Prognostic Analysis for Cardiogenic Shock in Patients with Acute Myocardial Infarction Receiving Percutaneous Coronary Intervention.

Cardiogenic shock (CS) is uncommon in patients suffering from acute myocardial infarction (AMI). Long-term outcome and adverse predictors for outcomes in AMI patients with CS receiving percutaneous coronary interventions (PCI) are unclear. A total of 482 AMI patients who received PCI were collected, including 53 CS and 429 non-CS. Predictors for AMI patients with CS including recurrent MI, cardiovascular (CV) mortality, all-cause mortality, and repeated-PCI were analyzed. The CS group had a lower central systolic pressure and central diastolic pressure (both < 0.001). AMI patients with hypertension history were less prone to develop CS ( < 0.001). Calcium channel blockers and statins were less frequently used by the CS group than the non-CS group (both < 0.05) after discharge. Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score, CV mortality, and all-cause mortality were higher in the CS group than the non-CS group (all < 0.005). For patients with CS, stroke history was a predictor of recurrent MI ( = 0.036). CS, age, SYNTAX score, and diabetes were predictors of CV mortality (all < 0.05). CS, age, SYNTAX score, and stroke history were predictors for all-cause mortality (all < 0.05). CS, age, and current smoking were predictors for repeated-PCI (all < 0.05).
