Baldness could indicate a risk of heart disease

IN a double blow, bald men may be at higher risk of coronary heart disease, according to a new study, but only if the hair is lost at the crown.
Men who bald from the front appear to carry no significant added risk for the clogged artery disease that can cause heart attacks, a report in online journal BMJ Open has said.
University of Tokyo researchers analyzed six studies on male pattern baldness and coronary heart disease conducted between 1993 and 2008 involving nearly 40,000 men in Europe and the US.
They showed that men who had lost most of their hair were more than a third more likely to develop coronary artery disease than those with hair.
The degree of baldness influenced the degree of risk, but again, only if the balding was at the crown, or vertex.
"These findings suggest that vertex baldness is more closely associated with systemic atherosclerosis (coronary heart disease) than with frontal baldness," said the study.
"Thus, cardiovascular risk factors should be reviewed carefully in men with vertex baldness, especially younger men, and they should probably be encouraged to improve their cardiovascular risk profile."
They urged further studies to confirm the findings.
The study said about 30-40 percent of adult men suffered from male-pattern baldness - and up to 80 percent by the age of 80.
The reasons for the association were unclear, but the study pointed to previous links between baldness and insulin resistance, diabetes, chronic inflammation or sensitivity to testosterone - all of which may lead to cardiovascular disease.
