BackgroundTo assess the prevalence trend and contributing factors of heart failure (HF) impairment with thalassemias at global, regional and national levels.MethodsData on HF impairment with thalassemias was collected from the Global Burden of Disease study. The absolute number and prevalence of the disease were systematically collected for each year, and the estimated annual percentage changes (EAPC) in HF impairment were calculated by gender, region and country to measure temporal trends.ResultsThalassemias have caused a significant global burden since 1990, and the case number of HF related to thalassemias has been steadily increasing. The highest case number of HF impairments with thalassemias is observed in China (7739 cases) and the highest prevalence is in Pakistan (1.61 per 100,000) currently. Besides, the middle sociodemographic index (SDI) region carries the highest burden of comorbid disease yet exhibits the most evident trend for improvement across the five regions (EAPC = -.98). The burden of thalassemias and comorbid HF is generally higher in males than females with the gender gap growing chasm in the future. Besides, the hotspots of HF impairment with thalassemias have gradually shifted to low SDI regions, though middle SDI regions still hold a relatively higher prevalence (.37 per 100,000) across different regions.ConclusionsThe burden of thalassemias and accompanying HF, as well as their temporal trends, vary greatly across countries and regions. These findings can improve understanding of these conditions and guide policymakers in developing appropriate policies to address disparities between countries.© 2023 Stichting European Society for Clinical Investigation Journal Foundation.
