A new meta-analysis of six studies, published in the British medical journal BMJ Open, has found a linkage between balding at the crown and coronary heart disease. While the top-line result of the study may be alarming, let us look first at some of the key facts.
- While the study showed a modest link between crown balding and heart disease, the link was not as strong as for other heart disease indicators such as smoking, obesity, cholesterol levels and blood pressure.
- There was no link established for men with a receding hair line.
- Key indicators of heart disease — high blood pressure, high LDL cholesterol, and smoking — are present in about half of Americans, according to the Center for Disease Control in America. So this is a health issue faced by many Americans, hair loss or not.
- Importantly, the most appropriate response if you have balding at the crown (and particularly crown balding at an early age), is not to worry first and foremost about your hair, but to concentrate on basic heart health and maintaining a healthy lifestyle. Discuss these issues and any concerns with your primary care physician.
Researchers at the University of Tokyo in Japan compiled information from six different studies with a combined total of almost 37,000 male participants. The studies were published between 1993 and 2008. Although one of the six studies did not find a link between baldness and coronary heart disease, the other five studies did find a link with the strength of the association differing in each study. In general, the more severe the balding at the crown, the more likely there was an association with heart disease. In addition, early onset of vertex balding — i.e. early balding at the crown — was found to be associated with the early development of more significant heart disease.
More research needs to be done to investigate the actual medical causes of the linkages shown.
An article on the BBC News website quotes a cardiac nurse from the British Heart Foundation discussing the findings:
“Although these findings are interesting, men who’ve lost their hair should not be alarmed by this analysis. Much more research is needed to confirm any link between male pattern baldness and an increased risk of coronary heart disease. In the meantime, it’s more important to pay attention to your waistline than your hairline.”
