Abstract

Background: Lead aVR provides prognostic information in various settings for patients with cardiovascular diseases. The present study aimed to investigate the prognostic value of a positive T wave in lead aVR (TaVR) for patients with acute pulmonary embolism (APE).Methods: We screened a total of 412 consecutive patients who were hospitalised with a diagnosis of APE between 2008 and 2018. We investigated electrocardiograms (ECGs) for the presence of a positive TaVR and classified other abnormal ECG findings. Additionally, clinical data, such as echocardiographic findings were recorded, and pulmonary embolism severity index (PESI) scores were calculated. The predictors of mortality at 30 days were investigated as the clinical outcome by logistic regression analysis.Results: In our study population, 54 patients (13.1%) died within 30 days. The prevalence of female gender, congestive heart failure, chronic obstructive pulmonary disease, and mean PESI scores were significantly higher in patients with a positive TaVR compared to those without it. Systolic blood pressure of patients with positive TaVR was significantly lower than that of patients without positive TaVR. In multivariate regression analysis; PESI scores (OR: 1.03; 95% CI: 1.01-1.04, p < .01), Right ventricular end-diastolic diameter (RVEDD) (OR: 1.07 95% CI: 1.01-1.13, p = .02), and a positive TaVR (OR: 4.41; 95% CI: 1.63-11.96, p < .01) were independently correlated with mortality.Conclusion: Positive TaVR, PESI scores, and RVEDD at hospital admission may have prognostic value in patients with APE. Positive T wave in lead aVR could be a useful marker in early risk stratification of pulmonary embolism.
