Regional Disparities Emerge in Global Stroke and Ischemic heart disease Trends
Updated June 25, 2025
While global rates of stroke and ischemic heart disease are generally on the decline, a new study in PLOS Global Public Health reveals concerning increases in specific regions. The research, led by Wanghong Xu at Fudan University, highlights a growing incidence of ischemic heart disease in East and West Sub-Saharan Africa, East and Central Asia, and Oceania.
Cardiovascular disease remains a leading cause of death and disability worldwide. Ischemic heart disease and stroke accounted for 16% and 11% of all deaths in 2019, respectively. Even though overall incidence has decreased, the distribution of this decline is uneven, with some regions experiencing an upward trend.
analyzing global data from 1990 to 2019, Xu’s team examined the incidence of both conditions and exposure to 87 potential contributing factors. They found that ischemic heart disease rates were higher than stroke rates. Over three decades, ischemic heart disease decreased from 316 to 262 per 100,000 people, while stroke declined from 181 to 151 per 100,000. However, the rise in ischemic heart disease in certain regions may be linked to factors such as diets high in trans-fatty acids, low calcium intake, high BMI, household air pollution from solid fuels, lack of exclusive breastfeeding, ergonomic factors in the workplace, vitamin A deficiency, and occupational exposure to particulate matter, gases, and fumes.
The study suggests that socioeconomic advancement and rapid lifestyle changes in some countries might potentially be contributing to higher rates of cardiovascular disease and stroke. These findings offer insights into potential mechanisms and opportunities for targeted interventions to address ischemic heart disease and stroke.
“This study profiles the significantly different incidence trends of ischemic heart disease and stroke across countries, identifies eight potential contributors to the disparities, and reveals the pivotal role of socioeconomic development in shaping the country-level associations of the risk factors with the incidences of the two cardiovascular diseases,” the authors said.
What’s next
Further research is needed to fully understand the complex interplay of factors driving these regional disparities in ischemic heart disease and stroke. Public health initiatives focused on modifiable risk factors could help mitigate the rising rates in vulnerable regions.
