Vitamin D and acute myocardial infarction

Area of Science:

• Cardiology
• Endocrinology
• Nutritional Science

Background:

• Vitamin D deficiency is widespread, affecting 30%-50% of the global population across all demographics.
• Beyond calcium homeostasis, vitamin D deficiency is increasingly recognized as a risk factor for cardiovascular disease.
• Hypovitaminosis D (low vitamin D levels) has been associated with acute myocardial infarction (AMI).

Purpose of the Study:

• To review the evidence linking vitamin D deficiency to acute myocardial infarction (AMI).
• To discuss the prevalence, prognostic impact, and potential mechanisms of this association.
• To highlight the need for further research into vitamin D supplementation for AMI risk reduction.

Main Methods:

• Review of existing clinical investigations and observational studies.
• Analysis of mechanistic data exploring the link between vitamin D and cardiovascular health.
• Discussion of controversial findings from interventional trials on vitamin D supplementation.

Main Results:

• Vitamin D deficiency is associated with both the incidence of AMI and increased morbidity and mortality.
• Low vitamin D levels may predispose patients to recurrent cardiovascular events and post-infarction complications.
• Mechanisms underlying the vitamin D-AMI association are being explored, but interventional trial results are inconclusive.

Conclusions:

• A significant association exists between vitamin D deficiency and acute myocardial infarction (AMI) in terms of prevalence and prognosis.
• Understanding the mechanisms is crucial for developing strategies to mitigate AMI risk.
• Further research, particularly well-designed interventional trials, is warranted to establish the efficacy of vitamin D supplementation in preventing AMI.
