Insertion/deletion polymorphism in the angiotensin-converting-enzyme gene and blood pressure during ergometry in normal males.
A sample of 66 healthy, unrelated males with normal blood pressure were studied for a possible association between an insertion/deletion polymorphism in the gene coding for the angiotensin converting enzyme and blood pressure response to physical exercise. No association was found between the polymorphism and systolic blood pressure at rest and during stress. Statistically significant associations between the polymorphism and diastolic blood pressure were observed during exercise and post-stress. At maximal workload, among homozygotes for the deletion, the mean diastolic blood pressure was 93 (+/- 10) mmHg, among homozygotes for the insertion it was 82 (+/- 8) mmHg, among heterozygotes it was 85 (+/- 10) mmHg. The difference was still statistically significant 3 minutes post-stress. The angiotensin converting enzyme polymorphism may be a marker for genetically determined differences in the response of the cardiovascular system to physical stress.
