Summary box
Prevention of coronary heart disease is most effective if targeted at people with high overall risk
First degree relatives of patients with premature myocardial infarction have double the risk of the condition
In the UK, about 20% of all admissions for myocardial infarction occur in patients with premature myocardial infarction
More than a third of admissions for premature myocardial infarction could be prevented by screening and treating first degree relatives
First degree relatives of patients with premature coronary heart disease are at increased risk of the disease. Compared with the general population, siblings have at least double the risk, because of shared lifestyle risk factors and genetic predisposition. Offspring and partners are also at increased risk. Relatives have an increased prevalence of modifiable risk factors including hypertension, dyslipidaemia, and smoking. Some guidelines recommend screening of relatives, but surveys indicate that this does not occur in practice. We propose that first degree relatives of patients admitted for premature myocardial infarction should be identified and then offered screening and treatment for risk factors of coronary heart disease.
Sources and selection
We searched OVID, Medline, and PubMed databases using combinations of the terms “family history”, “coronary heart disease”, “sibling”, “relative”, “premature coronary heart disease”, and “cardiovascular risk factors”. We cross checked the reference lists of papers identified as relevant. We undertook a web search using the same terms and searched the publication lists of relevant organisations such as the British Heart Foundation, European Society of Cardiology, and American Heart Association.
Increased risk of coronary heart disease
Coronary heart disease aggregates in families.1 In a cross sectional European survey (Euroaspire II), 10% of the siblings of 1289 patients with premature coronary …
