By 2030, global stroke fatalities might reach roughly 5 million 2023
According to a study, the global mortality toll from ischemic stroke increased from 2 million in 1990 to more than 3 million in 2019 and is projected to reach nearly 5 million by 2030.
Ischemic stroke is the most common form of stroke and is caused by a blockage in the blood supply to the brain.
Lize Xiong from Tongji University in Shanghai, China, stated, “This increase in the global death toll from ischemic stroke and the predicted further increase in the future is concerning, but ischemic stroke is highly preventable.”
Xiong added, “Our results suggest that a combination of lifestyle factors, such as smoking and a high-sodium diet, along with other factors, such as high blood pressure and body mass index, can increase the risk of stroke.”
The investigation was published in Neurology, a medical journal.
Researchers analyzed Global Health Data Exchange data from 1990 to 2019 for the study.
As the global population increased, the number of fatalities from ischemic stroke rose from 2.04 million in 1990 to 3.29 million in 2019.
Nevertheless, the rate of stroke decreased from 66 per 100,000 people in 1990 to 44 per 100,000 people in 2019.
“This decrease in the stroke incidence rate suggests that the global increase in the number of strokes is primarily due to population growth and aging,” said Xiong.
Researchers discovered that seven significant risk factors, including smoking, a high-sodium diet, high blood pressure, high cholesterol, kidney dysfunction, high blood sugar, and a high BMI, contributed to the increased incidence of strokes.
The database was then used to predict the number of fatalities for 2020-2030.
They discovered that the mortality toll due to ischemic stroke is projected to rise to 4,9 million by 2030.
Researchers estimated that the total number of stroke fatalities could reach 6,4 million if these risk factors are not controlled or eliminated.
A limitation of the study was that the quality and veracity of disease data from some countries could not be guaranteed because many lacked reliable data on strokes.
