What was a significant finding from the InterSTROKE study?

The significant finding from the InterSTROKE study is that ten modifiable risk factors account for 90% of strokes. This landmark study from a large, multinational cohort of patients provided valuable insights into the primary risk factors that contribute significantly to the occurrence of strokes. By identifying these factors, which include hypertension, smoking, and physical inactivity, healthcare professionals can focus on prevention strategies that target these key areas effectively. This finding emphasizes the importance of lifestyle modifications in reducing stroke risk on a global scale, aiding public health initiatives and individual patient care alike.

The other options do not reflect the crucial insights provided by the study; for example, while it is true that risk factors for strokes can vary geographically, the main takeaway emphasized the overwhelming impact of the identified risk factors collectively. The assertion that current smoking is not a risk factor directly contradicts the study's findings, as smoking was noted as a significant contributor to stroke risk. Lastly, stating high cholesterol as the only risk factor oversimplifies the complex nature of stroke risks, ignoring the multifactorial aspect highlighted by the study’s research.
