AbstractDigit ratio shows sexual dimorphism and is influenced by oestrogen and testosterone while in womb. This digit ratio can be used as biomarker to know about the age of occurrence of MI. we conducted digit ratio study on 25 men and 25 women both in case and control. In the normal healthy men the average 2D:4D ratio was 0.94 and in women it was 0.95. While in cases we found that 2D:4D ratio in men with MI was 0.98 and that in women it was 0.97 The average age of occurrence of MI was 58 in men and 53 in women. Hence, we are of opinion that digit ratio can be used as an non-invasive and inexpensive biometric screening procedure for early detection of MI.
