Dermatoglyphic studies of myocardial infarction patients
Insights
Dermatoglyphic traits, like fingerprint patterns, were linked to myocardial infarction (MI) risk in Japanese men. Higher whorl patterns and ridge counts may indicate increased susceptibility to heart disease, suggesting prenatal origins.
Area of Science:
- Genetics
- Cardiology
- Dermatoglyphics
Background:
- Dermatoglyphic traits are genetically determined and established early in development.
- Coronary heart disease, including myocardial infarction (MI), is a leading cause of mortality.
- Previous research has explored potential links between dermatoglyphic variations and various diseases.
Purpose of the Study:
- To investigate the association between dermatoglyphic patterns and myocardial infarction (MI) in a cohort of Japanese men.
- To compare digital dermal pattern types and ridge counts between MI patients and controls.
Main Methods:
- Analysis of dermatoglyphic traits (pattern types and ridge counts) in 834 Japanese men from a long-term heart disease study.
- Comparison of dermatoglyphic data between 100 MI patients and the remaining subjects.
- Statistical analysis of digital, hand, and individual pattern and ridge count variations.
Main Results:
- MI patients exhibited a significantly higher frequency of true whorls and double loops.
- Ulnar loops and tented arches were less common in MI patients.
- Total and absolute ridge counts were significantly higher in MI patients across all digits.
Conclusions:
- Specific dermatoglyphic patterns and higher ridge counts are associated with an increased risk of myocardial infarction.
- These findings suggest a potential antenatal origin for certain types of coronary heart disease.
- Dermatoglyphics may serve as a potential, non-invasive marker for predisposition to heart disease.
Abstract:
Dermatoglyphic traits were studied in a sample of 834 subjects selected from a cohort of some 8,000 living Japanese men, under a long-term study of heart disease in Hawaii. All of them were born between 1900 and 1919. Among them, 100 subjects had had positive diagnosis of myocardial infarction (MI). The present study included comparisons between the MI patients and the remaining group of all digital dermal pattern types and ridge counts by digit, by hand, and by individual. The MI patients had significantly higher frequency of true whorls, double loops and less ulnar loops and tented arches. Total and absolute ridge counts were significantly higher (less than 0.05) in all digits in favor of the MI patients. Similar trends were observed in analyses by digit and by hand. These observations suggest an antenatal origin of certain types of coronary disease.
