Insights
High arsenic levels in drinking water may be linked to myocardial infarction in young men lacking traditional risk factors. Arterial wall analysis revealed significant thickening, suggesting a novel cause for heart attacks in the young.
Area of Science:
- Cardiovascular Medicine
- Environmental Toxicology
- Pathology
Background:
- Myocardial infarction (MI) typically presents in older individuals with established risk factors.
- Coronary artery disease (CAD) is often associated with atherosclerosis, characterized by plaque buildup.
- Younger individuals experiencing MI often lack typical CAD risk factors, necessitating investigation into alternative etiologies.
Abstract:
Examination was made of the clinical history, the results of laboratory tests, of coronary arteriography, and of a histological study of the coronary arterial walls in two young men who had a myocardial infarction. The two men lived in a district where the drinking water had a very high level of arsenic (0.8 parts per million). Neither of the patients presented the risk factors which are usually associated with coronary arteriosclerosis. Neither of the patients presented the risk factors which are usually associated with coronary arteriosclerosis. A histological study of the pathological left ventricular wall, which was removed at operation, showed very characteristic features of fibrous thickening of the intima, with preservation of the internal elastic lamina, of the medial and of the adventitia. Such an arterial abnormality may effect the larger coronary arteries just as well as the medium and small ones. Clinical presentation of this condition is often in young subjects.
