Calcium Levels: A New Risk Factor for Heart Disease?
This study sheds light on the relationship between serum calcium and CMVD among individuals training at high altitudes, revealing that higher calcium levels are linked to increased disease prevalence. This could pave the way for new screening methods in these unique environments.
What they found: The study found that higher serum calcium levels are significantly associated with an increased prevalence of coronary microvascular disease among high-altitude trainees. Specifically, individuals with CMVD had an average calcium level of 2.42 mmol/L, compared to 2.37 mmol/L in those without the disease. The odds of developing CMVD increased by 39% for each 1 mmol/L rise in calcium.

From the abstract
Coronary microvascular disease (CMVD) is an emerging concern under high-altitude hypoxia, but data on modifiable correlates are scarce. Serum calcium regulates vascular tone and coagulation, making it a plausible candidate marker.
