A Trial Evaluating Vitamin D Normalization on Major Adverse Cardiovascular-Related Events Among Myocardial Infarction Patients (TARGET-D)
Death, Myocardial Infarction, Cerebral Vascular Accident
About this trial
This is an interventional treatment trial for Death
Eligibility Criteria
Inclusion Criteria:
- Patients, both male and female, >18 years old
- Undergone angiography for a MI (troponin positive [>0.04 ng/mL] and ACS diagnosis) within the past month
- Receive follow-up care at an Intermountain Healthcare facility
- Not taking or taking <1000 IU of vitamin D daily within the last 3 months
- Willing to provide informed consent and participate in follow-up visits
Exclusion Criteria:
- Hypersensitivity to vitamin D products
- History of previous vitamin D supplementation of >1000 IU daily within the past 3 months (i.e., >40% of the days during the past 3 months).
- Systemic disease (including terminal cancer, cirrhosis, end stage COPD, etc) with a reduced (<12 months) life expectancy
- Hypercalcemia (calcium levels >10.6 mg/dL)
- Subject participation in previous investigational interventional studies within 30 days of the current study.
- History of psychiatric illness/condition that would interfere with their ability to understand or complete the requirements of the study, a condition that in the opinion of the investigator or their designee places the subject at an unacceptable risk as a participant.
- Pregnant and/or lactating women and women of child bearing potential who are not using acceptable means of contraception as determined by the clinical investigators.

Standard of Care
Treatment
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.
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.
