Abstract

Background: Cardiovascular disease is the most common cause of death around the world. QT dispersion is one of the parameters that used for evaluation of ventricular arrhythmia. Primary PCI increases probability of coronary artery and reperfusion of the ventricular arrhythmia. The aim of this study was to determine effect of primary percutaneous coronary intervention (PCI) on ventricular repolarization through evaluation of QT dispersion in patient with acute myocardial infarction.

Methods: In this pre-post test study, 77 patients with acute ST with elevated myocardial infarction under primary PCI were investigated. The ECG and ST dispersion before PCI and 24 hours after PCI were determined and then the amount of QTd was calculated. The repeated measurement ANOVA was used to compare QTd of pre- PCI treatment and QTd in 24 hours after PCI. Data analysis was performed using statistical software SPSS ver.17.

Results: From 77 participants, 60 were male and 17 were female. 43 (55.8%) had a MI position in ANT, PRE, and EXT, 33 (42.9%) had in the INF, and only one person (1.3%) had a MI position in LAT. The results showed that mean QT dispersion in ECG, 24h after primary PCI, for most of measured variables was deceased compare to before primary PCI, but the difference was not significant.

Conclusions: The amount of QTd 24 hours after PCI decreased but its decline was not significant. With regards to lack of convenience data, more researches are recommended in this field.
