Identifying men at high risk of heart attacks: strategy for use in general practice
Insights
A new risk score effectively identifies men at high risk for heart attack and sudden cardiac death. This tool aids in early intervention for ischemic heart disease prevention.
Area of Science:
- Cardiology
- Preventive Medicine
- Public Health
Background:
- Ischemic heart disease (IHD) poses a significant health risk.
- Effective identification of high-risk individuals is crucial for prevention.
- Current screening methods may be costly or complex.
Purpose of the Study:
- To develop and validate a practical risk score for identifying men at high risk of acute myocardial infarction (AMI) or sudden ischemic death.
- To assess the predictive value of the devised risk score.
- To evaluate the added benefit of incorporating serum total cholesterol and electrocardiographic data.
Main Methods:
- A risk score was developed using factors: cigarette smoking, mean blood pressure, history of ischemic heart disease or diabetes mellitus, parental history of heart trouble, and angina presence.
- The top quintile of the risk score distribution was analyzed for its ability to identify incident IHD cases.
- The incremental predictive value of adding serum total cholesterol and ECG findings was assessed.
Main Results:
- The top fifth of the risk score identified 53% of men who subsequently experienced major ischemic heart disease events over five years.
- Adding serum total cholesterol and ECG data only marginally improved prediction to 59%, at a higher cost.
- The risk score is proposed for opportunistic use, particularly in general practice.
Conclusions:
- A simple, cost-effective risk score can identify a substantial proportion of men at high risk for IHD.
- This strategy complements population-based approaches to IHD prevention.
- Implementing this risk score can enhance awareness and promote preventive actions for ischemic heart disease.
Abstract:
A strategy was devised for identifying men at high risk of acute myocardial infarction or sudden ischaemic death. A risk score was devised using cigarette smoking, mean blood pressure, recall of ischaemic heart disease or diabetes mellitus diagnosed by a doctor, history of parental death from "heart trouble," and the presence of angina reported on a questionnaire. The top fifth of the score distribution identified 53% of ischaemic heart disease cases--that is, men who subsequently experienced major ischaemic heart disease over the next five years. The addition of serum total cholesterol concentration and electrocardiographic evidence only slightly improved prediction (to 59%) and would have considerably increased the cost and effort of screening. Using this risk score on an opportunistic basis could be particularly valuable in general practice. Management of this high risk group is regarded as appropriate medical care and is complementary to the population approach to preventing ischaemic heart disease. Such a strategy for reducing the incidence of and mortality from ischaemic heart disease in men at high risk would also increase professional and public awareness of the need for preventive action.
