Four specific signs of a heart attack or stroke
- A new study debunks the belief that heart attacks and strokes strike without warning, finding that almost all cases are preceded by specific warning signs.
- Researchers from Yonsei University College in South Korea and Northwestern University in the US analysed health records of over nine million people over two decades.
- The study identified four major risk factors: Above optimal levels of blood pressure, cholesterol, glucose, or smoking.
- It found that 99 per cent of individuals who experienced a major cardiac event had at least one non-optimal risk factor, with 93 per cent having two or more.
- High blood pressure was the most prevalent risk factor, affecting over 95 per cent of patients in South Korea and over 93 per cent in the US.
