Five years’ Epidemiological study of aortic dissection in 2017-2021 in Shahid Madani Hospital, Tabriz

Abstract

A comprehensive analysis of the epidemiological features of aortic dissections in Azerbaijan Province, Iran, and their influence on patient survival remains unexplored. This study aimed to determine the incidence of aortic dissection and identify the associated factors of mortality in these patients. Materials and Method this cross-sectional study was conducted using hospital records of patients diagnosed with aortic dissection between 2017 and 2021. The 3-month mortality was followed up via telephone calls. Then, independently associated factors of mortality were identified using a multivariate stepwise logistic regression analysis. Results: The overall incidence proportion of aortic dissections was 2.35 per 100000 populations. The mean hours of symptom onset to hospital arrival interval, diagnosis to treatment interval, and hospital admission to death interval were 73.3, 13.77, and 87.42. The all-cause mortality rate at 3 months was 52.5% 47 males (54%) and 26 females (50%). Multivariate analysis showed that higher age was independently associated with increased mortality. In contrast, patients with DeBakey Type III classification, hypothyroidism, and those who received either surgical treatment or medical treatment had a lower chance of mortality. Gender was not found to be associated with the outcome.
