Conclusion
Subclinical magnesium deficiency is a common and under-recognised problem throughout the world. Importantly, subclinical magnesium deficiency does not manifest as clinically apparent symptoms and thus is not easily recognised by the clinician. Despite this fact, subclinical magnesium deficiency likely leads to hypertension, arrhythmias, arterial calcifications, atherosclerosis, heart failure and an increased risk for thrombosis. This suggests that subclinical magnesium deficiency is a principal, yet under-recognised, driver of cardiovascular disease.
