New study finds 99% of heart attacks and strokes show early warning signs; Thai prevention urged
A new study reveals that nearly every major cardiovascular event—heart attack or stroke—is preceded by identifiable warning signs and risk factors. The research, which analyzed thousands of cases from South Korea and the United States, shows that more than 99% of heart disease incidents involved at least one measurable risk factor such as high blood pressure, elevated blood sugar, high cholesterol, or smoking. What makes the study notable is that it looked at patients’ medical data across a broad population, not just individuals already flagged as at risk, suggesting there may be fertile ground for earlier intervention and prevention. The implications are profound for health systems in Thailand, where cardiovascular disease remains a leading cause of death and disability, and where prevention and early detection have long been central policy goals.
