The Lethality of Strokes: An Overview

Stroke Mortality Rates

Strokes are a significant cause of death globally. In 2019, strokes were responsible for approximately 6.55 million deaths, making it the second-leading cause of death worldwide. This high mortality rate underscores the severe impact strokes have on global health. In the United States alone, strokes account for around 150,000 deaths annually, ranking as the third leading cause of death after coronary heart disease and cancer. Similarly, in Korea, strokes cause over 26,000 deaths each year, which translates to one death every 20 minutes.

Stroke Types and Their Impact

There are different types of strokes, each with varying degrees of lethality. Ischemic strokes, which account for about 80% of all strokes, are more common but generally less fatal than hemorrhagic strokes . Hemorrhagic strokes, although less frequent, result in higher mortality and disability-adjusted life years (DALYs) lost. In Korea, the 90-day mortality rate for ischemic stroke ranges from 3-7%, while it is significantly higher at 17% for intracerebral hemorrhage.

Global Disparities in Stroke Mortality

The burden of stroke mortality is not evenly distributed across the globe. Low- and middle-income countries bear a disproportionate share of stroke deaths. In 2005, 87% of stroke deaths occurred in these regions, and this trend is expected to continue. The age-standardized stroke-related mortality rate is significantly higher in low-income countries compared to high-income countries, being 3.6 times higher in the former. This disparity highlights the need for targeted interventions in resource-limited settings to reduce stroke mortality.

Risk Factors and Prevention

Several risk factors contribute to the high mortality rate associated with strokes. High systolic blood pressure, high body-mass index, high fasting plasma glucose, ambient particulate matter pollution, and smoking are the leading risk factors. Effective primary prevention strategies, such as controlling hypertension, managing diabetes, and reducing smoking rates, are crucial in mitigating these risks and lowering stroke mortality .

Conclusion

Strokes are a leading cause of death globally, with significant variations in mortality rates across different regions and types of strokes. While ischemic strokes are more common, hemorrhagic strokes are more deadly. The burden of stroke mortality is particularly high in low- and middle-income countries, necessitating urgent and effective prevention strategies. Addressing key risk factors can significantly reduce the global stroke mortality rate and improve outcomes for stroke patients.
