Burden of ischemic heart disease in the Middle East and North Africa (MENA) and attributable risk factors: An epidemiological analysis from 1990 to 2019

Introduction: Despite the burden of ischemic heart disease (IHD), there remains a paucity of research on the incidence, mortality, and burden of this condition in the Middle East and North Africa (MENA) regions. This study aimed to evaluate the epidemiology and the risk factors associated with IHD in the MENA region. Methods: This study was performed based on the GBD study 2019 data. We retrieved the data related to the epidemiology and burden of IHD, including prevalence, incidence, years of life lost due to premature death (YLLs), years lived with disability (YLDs), and mortality at the global level and in MENA countries across years and sexes. Results: IHD accounted for approximately 2.55 million (95 % UI 2.29-2.83) incident cases in MENA in 2019, with an age-standardized incidence rate of 613.87 (95 % UI 555.84-675.16) per 100 000 people, which has decreased by 9 % between 1990 and 2019. IHD accounted for 11.01 % of DALYs causes in MENA in 2019, an increase of 68 % compared to 1990. The DALYs rate from IHD increased with age in both men and women and was higher in men than in women in all age groups, except 85-89 years age-group, in 2019. Conclusion: The age-standardized prevalence and incidence of IHD are decreasing in MENA. However, this reduction is lower than the global level, which can be due to a weaker performance of the countries in the region in reducing the prevalence and incidence of the disease compared to the global average.
