Predicting coronary heart disease in middle-aged and older persons. The Framington study
Insights
A new risk function accurately predicts coronary heart disease (CHD) in adults. The model identifies individuals at high risk, enabling targeted prevention strategies for better cardiovascular health outcomes.
Area of Science:
- Cardiovascular Medicine
- Epidemiology
- Biostatistics
Background:
- Coronary heart disease (CHD) remains a leading cause of mortality worldwide.
- Accurate risk prediction is crucial for effective primary prevention strategies.
- Existing risk models may not fully capture risk across diverse adult populations.
Purpose of the Study:
- To develop and validate a novel risk function for predicting incident coronary heart disease (CHD).
- To assess the predictability of this risk function across different age groups and sexes.
- To compare the performance of the new risk function against established CHD risk profiles.
Main Methods:
- A prospective cohort study involving 1,025 men and 1,445 women aged 49-82 years, initially free of CHD.
- Development of a risk function incorporating high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, systolic blood pressure, left ventricular hypertrophy, and diabetes.
- Analysis of subsequent CHD events and assessment of risk prediction across deciles.
Main Results:
- The novel risk function demonstrated significant predictability for incident CHD.
- Less than 2% of subsequent CHD cases occurred in the lowest risk decile.
- The highest risk decile accounted for 25% of male and 37% of female CHD cases.
- Predictability was consistent across specific age groups and comparable to traditional risk profiles at younger ages.
Conclusions:
- The developed risk function provides a robust tool for identifying individuals at high risk of developing coronary heart disease.
- This model offers improved risk stratification, particularly for older adults.
- The findings support the integration of this enhanced risk assessment into clinical practice for personalized CHD prevention.
Abstract:
Of 1,025 men and 1,445 women, aged 49 to 82 years, who were free of coronary heart disease (CHD), 79 men and 63 women subsequently had CHD. Using a risk function based on cholesterol in the high density and low density lipoproteins, systolic blood pressure, left ventricular hypertrophy, and diabetes, less than 2% of the subsequent CHD cases were found in the lowest decile of risk, whereas 25% of the cases for men and 37% for women were found in the highest decile. Predictability held for each specific age group. This predictability was at least as good as that obtained by the usual CHD risk profile at younger ages.
