The high 2D:4D finger length ratio effects on atherosclerotic plaque development.
BACKGROUND
The index finger to ring finger length ratio (2D:4D) of the right hand are affected by prenatal testosterone levels in male. To date, it has been determined that the high 2D:4D ratio is related to the myocardial infarction, however no research has revealed the relationship between the high 2D:4D ratio whose coronary artery shows atherosclerotic plaque development.


OBJECTIVE
The aim of this study was to display the relationship between the 2D:4D ratio and atherosclerosis formation in male autopsy cases.


METHODS
We designed a study in 100 heterosexual male autopsies whose mean age was 21.4+/-2.47 (range between 17 and 25). The 2nd and 4th digits were measured on the palmar surface of the right hand and taken the right coronary artery to show the atherosclerotic plaque development.


CONCLUSIONS
Grade 3 group had significantly higher 2D:4D ratio compared to Grade 1 and Grade 2 groups (p=0.02 for both).
