Increase by more than a million deaths from ischemic strokes from 1990 to 2019, and scientists predict that these deaths are expected to increase to nearly five million by 2030.

Specifically, according to study published in the American Academy of Neurology’s online medical journal Neurology, worldwide deaths from ischemic stroke, the most common type of stroke, were 2.04 million in 1990 and rose to 3.29 million in 2019. The scientists they predict that the increase will be dramatic by 2030.

Study author Liz Xiong, from Tongji University in Shanghai, calls this increase “alarming, but ischemic stroke is largely preventable”. “Our results demonstrate that the combination of lifestyle factors, such as smoking and a high-sodium diet, together with other factors, such as high blood pressure and a high body mass index, can lead to an increased risk of stroke.” , he adds.

The researchers found that seven risk factors have contributed to the increased number of strokes: smoking, high sodium diet, high blood pressure, high cholesterol, kidney dysfunction, high blood sugar and high body mass index. In fact, they estimated that if these risk factors are not controlled or prevented, then the total number of deaths could reach 6.4 million by 2030.

However, the stroke rate decreased from 66 strokes per 100,000 people in 1990 to 44 strokes per 100,000 people in 2019. population and ageing,” he explains.

For the study, researchers analyzed data from the Global Health Data database
