Abstract

Abstract : This study tracked 4134 patients post burn injury and found that dying from a cardiovascular cause in males 15 to 60 years is 10 times higher than similarly aged males. These findings indicate that screening for cardiac disease should become standard practice post burn injury. Abstract : BACKGROUND: Burn injury is responsible for both acute and ongoing inflammation, resulting in systematic changes impacting the cardiovascular, hepatobiliary, endocrine, and metabolic systems, but there is minimal investigation into long-term clinical outcomes. This study aimed to investigate mortality due to cardiovascular related long-term postburn injury. METHODS: This was a retrospective cohort study linking a burns unit database with mortality outcomes from a Registry of Births, Deaths and Marriages. Data were extracted from the Australian Institute of Health and Welfare and stratified into three age groups: 15 to 44 years, 45 to 64 years, and 65+ years. Mortality rate ratios (MRRs) and 95% confidence interval (CI) were calculated to compare the burns cohort mortality incidence rates with the national mortality incidence rates for each of the three age groups. Logistic regression was used to identify demographic and clinical factors associated with cardiovascular mortality. RESULTS: A total of 4, 134 individuals in the database were analyzed according to demographic and clinical variables. The 20-year age-standardized cardiovascular mortality rate for the burns cohort was significantly higher compared with the Australian population (250.6 per 100, 000 person-years vs. 207.9 per 100, 000 person-years) (MRR, 1.21; 95% CI, 1.001–1.45). Cardiovascular mortality was significantly higher in males aged 15–44 and 45–64 years had a cardiovascular mortality rate significantly higher than the Australian population (MRR = 10.06, 95% CI 3.49–16.63), and (MRR = 2.40, 95% CI 1.42–3.38) respectively. Those who died of cardiovascular disease were more frequently intubated postburn injury ( p = 0.01), admitted to intensive care ( p < 0.0001), and had preexisting comorbid physical conditions (60.9% vs. 15.0%, p < 0.0001). CONCLUSION: Survivors from burn injury, especially young males, are at increased long-term risk of death from cardiovascular disease. Increased screening and counseling pertaining to lifestyle factors should be standard management postburn injury. Longitudinal observation of physiological changes, investigation of mechanistic factors, and investigation of interventional strategies should be instituted.
