Objective—We tested the hypothesis that reduced plasma 25-hydroxyvitamin D associates with increased risk of ischemic heart disease, myocardial infarction, and early death.

Methods and Results—We measured baseline plasma 25-hydroxyvitamin D in 10 170 women and men from the Danish general population without vitamin D–fortified food.
During 29 years of follow-up, 3100 persons developed ischemic heart disease, 1625 myocardial infarction, and 6747 died.

Decreasing plasma 25-hydroxyvitamin D levels were associated with increasing risk of ischemic heart disease, myocardial infarction, and early death as a function of seasonally adjusted percentile categories (P for trend, 2×10?5–3×10–53).

Comparing individuals with plasma 25-hydroxyvitamin D levels at the 1st to 4th percentile with individuals with levels at the 50th to 100th percentile, the multivariable adjusted risk was increased by

• 40% (95% CI, 14% – 72%) for ischemic heart disease, by
• 64% (25% – 114%) for myocardial infarction, by
• 57% (38% – 78%) for early death, and by
• 81% (40% – 135%) for fatal ischemic heart disease/myocardial infarction.

In the meta-analyses of 18 and 17 studies, risk of ischemic heart disease and early death were increased by 39% (25% – 54%) and 46% (31% – 64%) for lowest versus highest quartile of 25-hydroxyvitamin D level.

Conclusion—We observed increasing risk of ischemic heart disease, myocardial infarction, and early death with decreasing plasma 25-hydroxyvitamin D levels.
These findings were substantiated in meta-analyses.

This is for people who did not have vitamin D fortified foods
Wonder about vitamin D supplements
Wonder length of delay between the vitamin D measurement and death: months, years, decades?
