- Abstract
Background: Aortic dissection is a rare but potentially lethal disorder and may be associated with electrocardiogram (ECG) changes. In this study, we aim to investigate ECG-related parameters alongside clinical presentations of type A aortic dissection to come up with the predictive factors for the severity of the disease and its mortality rate., Methods: In this retrospective study, 201 patients with type A aortic dissection were studied between March 2015 and March 2020. Two expert cardiologists blinded to the diagnosis studied former and new patients' ECGs and recorded changes., Results: Two-hundred and one patients, including 143 (71.1%) men and 58 (28.9%) women, presented with acute dissection of the aorta, were studied. Forty-four (21.8%) and 84 (41.7%) patients had ST-segment elevation and depression in ECG, respectively. Bivariate analysis revealed that higher heart rate (p = 0.006), longer QTc (p = 0.044), and ST-segment elevation in aVR lead (p = 0.044) were associated with mortality in the patients. Multivariate regression showed higher heart rate (OR = 1.022, CI = 1.003-1.041, p = 0.012) and ST-segment elevation in aVR (OR = 4.854, CI = 2.255-10.477, p < 0.001) were independently associated with increased odds of mortality in aortic dissection patients. ROC curve analysis showed heart rate equal to or >60 per minute (AUC = 0.625, sensitivity = 86%, specificity = 10%, p = 0.019) and ST-segment elevation in aVR >0.5 mm (AUC = 0.854, sensitivity = 75%, specificity = 92%, p < 0.001) were associated with a higher mortality rate., Conclusion: Heart rate equal or >60 and ST-segment elevation >0.5 mm in aVR lead can be used as predictive factors for mortality of patients with type A aortic dissection., Competing Interests: Declaration of Competing Interest The authors declare no competing interests., (Copyright © 2023 Elsevier Inc.
