Abstract

INTRODUCTION: The entire human body is clothed with the skin which happens to be the largest and most important organ of the body. It performs many vital functions in the life of an individual, viz, it protects and safeguards the body from the vagaries of the weather, maintains the body temperature and saves the internal organs of body from injuries. However, the skin on the ventral sides of hands and plantar sides of feet is exclusively designed and is corrugated with the ridges and configurations which are functionally useful as they help in grasping without which the objects would easily slip away from hands. AIMS AND OBJECTIVES: 1. To study the finger and palmar dermatoglyphic pattern in MI patients. 2. To establish sexual and digital differences in dermatoglyphic patterns of MI patients. 3. To compare the dermatoglyphic configurations of MI with the controls. 4. To find out whether a specific dermatoglyphic trait/feature exists in MI and whether it is significant. 5. To observe the usefulness of dermatoglyphic patterns in serving as predictor of MI. MATERIALS AND METHODS: The present study was conducted in the Institute of Anatomy, Madras Medical College, Chennai-3. The palm prints of the patients admitted in the Institute of Cardiology, Madras Medical College, Chennai-3 with myocardial infarction were taken. Of them 120 were Males and 30 were females. Similarly the palm prints of equal number from the normal healthy individuals in and around Chennai were taken as controls. The individuals with systemic hypertension, dyslipidemia and previous history of coronary heart disease were excluded from controls. The study group (Cases) included the persons admitted in the Institute of Cardiology with chest pain, in whom the diagnosis of myocardial infarction was confirmed by E.C.G and some of them by Coronary Angiography. Patients and controls were informed about the procedure in detail and their consent was obtained to conduct the study. CONCLUSION: The dermatoglyphic features of the patients with Myocardial Infarction has been studied from the dermatoglyphic prints taken by “Ink Method” and subjected to analysis to find out variations between patients and controls. • The percentage of loop, arch and whorls is 54.9%, 8.3% and 36.8% respectively in MI and 59.4%, 13.2% and 27.4% respectively in controls. Thus, there is decrease in loops and arches with increase in whorls in most of the digits of both hands in MI. • There is significant decrease in loops in middle finger of both hands (p<0.05) and arches in thumb and index finger of both hands (p<0.05) in MI. • There is significant increase in whorls in thumb (p<0.05) and little finger (p<0.05) of both hands in MI. • The mean value of TFRC is 127.5 and 103 in MI and controls respectively. The increase in the mean value of total finger ridge count (TFRC) in MI patients as compared to controls is statistically significant in the present study (p< 0.01). • The mean value of AFRC is 185 in MI and 170 in controls. Thus, there is increase in the mean value of absolute finger ridge count (AFRC) with statistically significant increase in female patients of MI (p<0.005). • There is decrease in the frequency of axial triradii near wrist (t) with increase in the frequency of t’, t” and tt” in both sexes and in both hands and distal displacement of axial triradii in M+F and in left hand but not statistically significant. • There is significant increase in the frequency of ‘4’ palmar triradii (p<0.05) with significant decrease in the frequency of ‘8’ palmar triradii (p<0.05). • The mean value of ab ridge count in MI is 39 and in controls it is 40 and there is no significant decrease in the mean value of ab ridge count in male patients of MI, but significant decrease is observed in female patients (p<0.05) when compared to controls. • There is significant increase in the mean value of atd angle in both hands of MI patients (p<0.01) and the mean value of atd angle is 41 in MI and 39 in controls. Thus from the present study, it appears that there do exist variations in the dermatoglyphic patterns in Myocardial Infarction. The specific features of dermatoglyphic patterns present in it raise the possibility of using dermatoglyphic study as a mass screening program for prevention of MI.
