About the INTERHEART Study
The INTERHEART study was a landmark global case-control study that identified nine modifiable risk factors accounting for over 90% of the population-attributable risk for a first heart attack.
Key Finding
Over 90% of heart attacks are preventable by addressing these nine modifiable risk factors.
The Nine Risk Factors
Harmful Factors (Increase Risk)
- Smoking: Current or former smoking
- Abnormal Blood Lipids: High LDL or low HDL cholesterol
- Hypertension: High blood pressure
- Diabetes: History of diabetes
- Abdominal Obesity: Measured by waist-to-hip ratio
- Psychosocial Factors: Stress, depression, life events
Protective Factors (Decrease Risk)
- Regular Fruit and Vegetable Consumption
- Regular Physical Activity
- Moderate Alcohol Consumption
Global Applicability
The INTERHEART study was conducted in 52 countries and found that these nine factors were consistent across all geographic regions, ethnic groups, and both sexes.
Clinical Significance
The INTERHEART Risk Score provides a simple, actionable tool for clinicians and individuals to assess heart attack risk and focus prevention efforts on modifiable lifestyle factors.
