They credited this to high levels of testosterone, the male sex hormone, in those who go bald earlier.
Research from the University of Texas found large waist measurements, relative to hip size, were linked to early signs of heart disease.
This confirms other research that waist size, rather than overall body weight, is a key indicator of heart disease.
The study of 2,744 people suggests that a waist size of 32ins (81cm) for a woman and 37ins (94cm) for a man represents a "significant" raised risk.
Having a bad heart doesn't mean you can skip exercise, doctors said Wednesday. In fact, it may even help your heart to repair itself. Research presented at the European Society of Cardiology meeting showed that exercise sparks the creation of new heart vessels.
In a small study of 37 people at Leipzig University in Germany, Dr. Robert Hollriegel found that people with serious heart failure who rode a bike for up to 30 minutes a day for four months produced new stem cells in their bones.
