Arrhythmias in patients with acute ST elevation myocardial infarction

Purpose: Arrhythmias and conduction disturbances are common during acute myocardial infarction (AMI) and a major cause of death in the pre-hospital phase. The aim of this study was to investigate common predictors for all arrhythmias in patients with ST elevation AMI (STEMI) during in-hospital phase. Materials and Methods: Ninety patients (74 male, 55 ±11 years) with acute STEMI were included. Clinical charesteristics were recorded and laboratory parameters including serum C- reactive protein (CRP), creatinine kinase MB (CKMB) and potassium levels were measured. The patients were divided into two groups according to development of arrhythmias.Results: Group 1 (n=42) patients had new onset arrhythmias and Group 2 (n=48) patients had without arrhythmias. Median baseline CRP levels were significantly higher in group 1 (36.6 (21.8-77) mg/dl vs. 21.8 (24.2-30.7) mg/dl), especially in patients with atrial fibrillation and ventricular arrhythmias. Logistic regression analysis showed that baseline higher CRP level, peak CKMB level and inferior localization of AMI were significantly associated with the development of arrhythmia following AMI. Conclusion: Levels of CRP and CKMB and inferior infarct localization have predictive values for all the arrhythmic events during AMI. CRP levels were found to be associated with both atrial and ventricular arrhythmias. The assessment of CRP levels can be used to detect patients at high risk for arrhythmic events after STEMI.
