Abstract: The aim of this study is to determine the effects of dermatoglyphic patterns in inherited Essential hypertension disease which could be useful for early diagnosis and preventive care. The sample studied for this research was obtained from 40 patients with inherited Essential hypertension disease and 20 normal subjects without any symptoms of Essential hypertension disease until 2 generations ago. Print of their palm and fingers was obtained in two groups by printing ink. Patterns of finger tips, ATD angles, A-B ridge and the different types of minutiae were located, identified and quantified visually inside of four sectors of fingerprints. The result of this study showed two patterns of finger tips; Whorl and arch in diseases are more than normal people. The most common tips in normal people is loop. In average the number of the A-B ridge in female illnesses and male normal are respectively more on average than female normal and male illnesses. The ATD angle is lower in patients than in normal. Results of the survey on minutiae showed that frequency of the ridge Ending (E) is between 32-52.52 with the highest frequency. Frequency of Bifurcation (B) is lower than the ridge ending which it is between 17.39-35% in left hand, but in right hand the second most patterns is convergence (C) which is between 14.13-38.66%. The third most patterns in left hand was observed in pattern convergences (C) with a percentage between 8.62-32.6, but in right hand the third most patterns is bifurcations (B), which is between 3.57-24.81%. Also in some sector of fingers significant difference was found.
