Can You Measure Your Heart Attack Risks With Your Finger?
February 22, 2007
The length of a baby boy's fingers could indicate whether he will be at risk of a heart attack in early adulthood.
An analysis of more than 150 male heart attack victims showed that boys with shorter ring fingers could experience heart problems as early as age 35.
This is because these boys tend to have lower levels of the hormone testosterone, which protects against heart attack; genes that affect testosterone production also determine finger development.
The average male tends to have a ring finger about 2 percent longer than the index finger, and the ratio remains the same throughout life. The longer the ring finger, the greater the testosterone production. Short ring fingers did not mean that a heart attack was inevitable, but could serve to alert parents that risk-reduction measurers should be taken.
