An observational study presented at the EuroPrevent 2017 conference of the European Society of Cardiology suggests that the risk of heart disease is high for adult men with more gray hair.
The researchers examined 545 adult men with coronary artery disease and divided them into several groups according to amount of their gray hair.
Level of gray hair is gradeded into four: 1 for pure black hair, 2 for more black hair than white, 3 for equal amount of black and white, 4 for more white than black hair and 5 for pure white hair.
Multivariate regression analyses was used and discovered that age, level of gray hair, high blood pressure, and dyslipidemia predicted atherosclerosis coronary artery disease differently.
Patients with coronary heart disease had greater whitening grade level, hair graying shows real age and indicates cardiovascular risk.
