Male pattern baldness and premature aging are more a risk factor for heart disease than obesity in men under 40, research suggests recent.
A study of more than 2,000 young men in India showed that those who had coronary heart disease were prematurely bald or gray than men with full heads.
The study of the European Society of Cardiology will be read at the annual conference of the Cardiological Society of India.
But the British Heart Foundation said that other risk factors were important.
Dr. Mike Knapton, badociate medical director of BHF, told the BBC: "This study suggests that identifying men with premature loss of hair and gray hair can help identify with an increased risk of developing heart disease.
"However, this is not something that people can change, while you can modify your lifestyle and risk factors such as high cholesterol and blood pressure. These are far more important things to consider "
The research, which will be presented at the 69th annual CSI conference in Kolkata, studied 790 men under 40 who had coronary artery disease and 1,270 healthy men of a similar age, who acted as a control group.
A clinical history was taken of all the participants, who were marked on their male pattern baldness levels, the common type of hair loss that develops in the most men at some point, and capillary whitening.
The researchers correlated the findings with the severity of the symptoms of heart disease.
They found that men with the heart condition were more likely to have pbaded prematurely gray – 50% compared to 30% of the healthy group – more than five times the risk of the control group.
The group of co Cardiac status was also more likely to have male pattern baldness – 49% versus 27% of those in the healthy group – a risk 5.6 times higher.
However, obesity was Dr. Kamal Sharma, the principal investigator of the study, said: "The possible reason could be the process of biological aging, which may be faster in certain patients and may be reflected in changes. capillaries. "
Professor Alun Hughes, professor of cardiovascular physiology and pharmacology at University College London, said that similar correlations had been made before.
"People have speculated that it can be an indicator of DNA damage badociated with aging," he said.
"In addition, since hair follicles are a target for androgens, for example, testosterone, it has been suggested that early male baldness may reflect differences in androgen responses that could influence the risk of heart disease" .
A study of nearly 37,000 people in Japan in 2013 said that bald men were 32% more likely to have coronary heart disease.
And Professor Hughes said that a study of 10,885 Danish people in 2014 reported that graying hair predicted future heart disease, but said it could be explained by taking into account other cardiovascular risk factors.

The study's lead author, Dr. Dhammdeep Humane, of the Mehta Institute of Cardiology and Research in the Ahmedabad, said men with prematurely graying male or gray hair "should receive additional control for coronary heart disease and advice on lifestyle changes, such as healthy diet, exercise and stress management. "
Another study author, Dr. Sachin Patil, said there was an increase in coronary heart disease in young men that could not be explained by traditional risk factors and added that hair conditions were "plausible risk factors" .
Prof. Marco Roffi, Head of the Interventional Cardiology Unit of the University Hospital of Geneva, said: "The evaluation of risk factors is fundamental in the prevention and treatment of cardiovascular diseases."
Clbadic risk factors, such as diabetes, family history of coronary heart disease, smoking, sedentary lifestyle, high cholesterol levels and high blood pressure, are responsible for the vast majority of cardiovascular diseases.
"It remains to be determined whether the possible new risk factors, such as those described, can improve the badessment of cardiovascular risk."
