Abstract 183: Life-Threatening Arrhythmias in Patients Hospitalized with Acute Coronary Syndrome: Data from Latvian Registry 2008-2010
Purpose. Despite the major improvements in the care of patients with acute coronary syndrome (ACS), life - threatening arrhythmia (LTA) remains a common complication of myocardial infarction (MI). We have analyzed the rate of LTA in first hours after hospitalization in patients presenting with acute coronary syndrome and receiving different treatment strategies. Materials and methods. The data from Latvian registry of ACS in years 2008-2010 were analyzed. LTA was defined: complete AV block, unsustained/ sustained ventricular tachycardia (VT), ventricular fibrillation (VF).
Results. In STEMI cohort, the incidence of LTA was significantly lower in PCI group after six hours (p<0.05) than in patients receiving thrombolysis. In first two hours LTA incidence was higher in PCI patients, what we can be explained with earlier reperfusion changes and electrical instability. In non-STEMI cohort, the incidence of LTA was significantly lower than in STEMI patients (p<0.01), but it was higher in non-invasive group compared to invasive treatment group. LTA rate was significantly
reduced in statin users (p<0.05).
Conclusions. Despite the more aggressive treatment strategy, incidence of LTA remains high in ACS patients. Arrhythmias are often observed earlier in patients after PCI and later after thrombolysis. Earlier PCI can decrease late complication rate and potentially improve
survival in STEMI patients.
