Lancet Neurology: Stroke may become the "top killer" of world health

"Stroke", also known as "Stroke", according to the "Guiding Standards for the Prevention and Treatment of Stroke in China (2021 Edition)" issued by the National Health Commission, stroke is one of the major diseases that endanger the health of our nationals, with a high incidence and high incidence.
The characteristics of disability rate, high mortality rate and high recurrence rate
.

Data show that in 2019, the incidence of ischemic stroke in China is 1700/100,000, and the incidence of hemorrhagic stroke is 306/100,000.

Recently, the GBD 2019 Stroke Cooperation Organization published a new study in the Lancet Neurology, which investigated and analyzed the burden of stroke and its risk factors in various countries and regions around the world from 1990 to 2019.
The title is "Global, regional, and national burden ofstroke and its risk factors, 1990–2019: a systematic analysis for the Global Burden of Disease Study 2019"
.

This study surveyed 204 countries and regions from 1990 to 2019, and analyzed the incidence, morbidity, mortality, disability-adjusted life years (DALY) and DALY associated with 19 risk factors.
Population attributable score (PAF), etc.
, and based on this, through the grouping of gender, age, and World Bank country income level, further explored stroke-related diseases such as ischemic stroke, cerebral hemorrhage, and subarachnoid hemorrhage
.

The results of the study show that in 2019, there were 12.
2 million stroke cases, 101 million stroke cases, 143 million disability-adjusted life-year (DALY) stroke cases, and 6.
55 million stroke deaths
.

Globally, stroke is still the second leading cause of death, accounting for 11.

In addition, if divided according to World Bank income standards, most of the global stroke medical burden is in low-income and low-middle-income countries
.

Globally, in the past 30 years, the total number of stroke-related DALYs due to risk factors has increased significantly.

Starting from the risk factors, researchers found that from 1990 to 2019, risk factors such as high BMI, high fasting blood sugar, high LDL cholesterol, renal dysfunction, high red meat diet, alcohol consumption, and second-hand smoke were associated with stroke.
The total number of DALYs has increased.
In 2019, the five main specific risk factors for death and disability from stroke include high blood pressure, high BMI, high fasting blood sugar, environmental particulate pollution and smoking
.

At the same time, it is worth paying attention to the relationship between age and incidence trend.
Researchers have found that the incidence of stroke tends to be younger
.

Although the absolute numbers increased during the study period, the age-standardized rate decreased between 1990 and 2019.

In summary, the study shows that from 1990 to 2019, although the age-standardized rate dropped sharply, especially among the elderly over 70, the number of deaths caused by strokes and strokes continued to increase sharply each year
.

In addition, between 1990 and 2019, the risk factor with the fastest increase in stroke was the BMI index
