Relation between severity of magnesium deficiency and frequency of anginal attacks in men with variant angina.

Abstract Objectives . We evaluated whether the severity of magnesium deficiency was correlated with the frequency of attacks of variant angina. Background . Magnesium deficiency may be associated with the development of variant angina. However, the relation between the activity of variant angina and magnesium deficiency remains to be elucidated. Methods . We assessed the body magnesium status of 18 men with variant angina: Group 1 (≥4 attacks/week, n = 7) and Group 2 ( Results . Group 1 showed a higher 24-h magnesium retention rate (mean ± SEM 63.5 ± 7.6% vs. 24.9 ± 2.7%, p Conclusions . Data suggest that the magnesium status of men with variant angina is closely related to disease activity.
