Summary

This trial will test whether raising vitamin D levels in people who have had a heart attack can reduce the risk of having another heart-related problem.

Who is the study for?
This trial is for adults over 18 who've had a heart attack in the past month, are not on high doses of vitamin D, and can follow up at an Intermountain Healthcare facility. It's not for those with certain psychiatric illnesses, pregnant or breastfeeding women without contraception, recent other trial participants, or people with terminal illnesses.
What is being tested?
The study tests if normalizing Vitamin D levels (>40 ng/mL) in heart attack patients reduces cardiovascular events. Participants will be randomly divided into two groups: one receiving standard care and the other managed to achieve targeted Vitamin D levels.
What are the potential side effects?
Vitamin D3 supplementation may cause side effects like hypercalcemia (high calcium levels), which could lead to kidney stones or bone pain. However, these are generally rare when Vitamin D is taken as directed.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: TreatmentExperimental Treatment1 Intervention
Patients randomized to the treatment arm will have a 25\[OH\] Vit D test performed, a sample taken and stored for future tests, and completion of a PHQ-9 depression survey. If at baseline a patient has a 25\[OH\] Vit D \>40 ng/mL then follow-up testing will occur 1 year from baseline and the patient will continue current treatment strategy (no supplementation or current supplementation dosage). If baseline 25\[OH\] Vit D levels are \<40 ng/mL then the patient will initiate or increase dose and return in 3 months (±15 days) to determine 25\[OH\] Vit D level. At 3 months, if 25\[OH\] Vit D \>40 ng/mL then current dose should be kept and the patient will return in 1 year for follow-up testing. However, if 25\[OH\] Vit D \<40 ng/mL then patients should double current dose and test again in 3 months. This should occur until 25\[OH\] Vit D reaches a level \>40 ng/mL and once achieved, the patient will return in 1 year for follow-up 25\[OH\] Vit D testing.
Group II: Standard of CareActive Control1 Intervention
Patients randomized to the standard of care arm will have a 25\[OH\] Vit D test performed, a sample taken and stored for future tests, and completion of a PHQ-9 depression survey at baseline and at study conclusion. No other contact is planned with the standard of care patients. Follow-up will be done by the querying of electronic records, which includes any 25\[OH\] Vit D testing, use of vitamin D supplementation, and outcomes.
