Trends and predictive research on the global burden of ischemic heart disease from 1990 to 2021: an analysis of the Global Burden of Disease study 2021

From 1990 to 2021, the number of IHD cases in the world and its forecast analysis showed an upward trend, mainly affected by population growth and aging. The disparity of medical burden in areas with low, middle and medium development levels is worsening. The importance of regional rankings of risk factors for IHD has also shifted due to global economic changes over the past 30 years. This study highlights the challenges faced in managing IHD and calls for governments and institutions to adopt multidimensional public health strategies encompassing age, risk factors, gender, and predictive models to address the growing number of cases and other health problems. These findings will guide health policies to effectively control clinical stress in IHD by prioritizing regional risk factors for targeted interventions and individualized prevention for high-risk populations, while also ensuring efficient use of health resources.
