TI  - Ischemic changes in lead aVR is associated with left ventricular thrombus or high-grade spontaneous echocontrast in patients with acute anterior myocardial infarction
AB  - Objective: The aim of this study was to investigate the relationshipbetween ischemic changes in the lead aVR and leftventricular thrombus (LVT) or high-grade spontaneous echocontrast (SEC) in patients with acute anterior myocardial infarction(MI).Methods: Quantitative T wave polarity in lead aVR (TPaVR)and ST segment deviation in the lead aVR (STaVR) measuredfrom a surface electrocardiogram (ECG), as well as theabsolute numerical values, were recorded. The ST/TPaVRratio was obtained by dividing the larger absolute value bythe smaller. The presence of LVT or high-grade SEC wasrecorded using echocardiograpy. The SYNTAX score (SS),clinical SS (cSS), and residual SS (rSS) were calculated fromangiography results.Results: A total of 34 patients with LVT or high-grade SECwere included in Group 1. Group 2 comprised 170 patients whodid not have any LVT or high-grade SEC. The P wave duration,V2 ST-segment elevation, TPaVR, cSS, and ST/TPaVR ratiowere significantly higher in Group 1. The ejection fraction (EF)and STaVR were significantly higher in Group 2. The EF (Oddsratio [OR]: 0.9, 95% confidence interval [CI]: 0.833–0.973;p=0.008), TPaVR (OR: 1.454, 95% CI: 1.074–1.967; p=0.015),and ST/TPaVR ratio (OR: 1.6, 95% CI: 1.307–1.959; p<0.001)were determined to be independent predictors for Group 1.Conclusion: Ischemic changes in the lead aVR are closelyassociated with LVT or high-grade SEC in anterior MI patients.
