A study of 2nd to 4th digit ratio (2D: 4D) in relation to hypertension in north Indian males and its implications for risk factors in coronary heart disease

The index finger to ring finger ratio (2D: 4D) of the hands are affected by prenatal sex steroids. Furthermore, 2D: 4D ratio is related to myocardial infarction and coronary artery diseases, however no research has reported the relationship between the 2D: 4D ratio and hypertension in Indian male. In this study, we examined 2D: 4D finger length ratio in 100 Indian male with history of hypertension and 100 controls without history of hypertension. The 2D: 4D ratio was more in hypertensive group and p value was statistically significant in control & hypertensive group. It was higher in left hand among both the groups. This finding supports the suggestion of 2D: 4Dratio to serve as a predictor for hypertension which is the major risk factor for cardiovascular diseases.
