Omega-3 and vitamin D supplements tied with lesser hospitalizations in HF patients
A study published in JACC: Heart Failure suggested that patients with and without type 2 diabetes who took omega-3 and vitamin D supplements were less likely to be hospitalized for heart failure, compared with those who took placebos.
The primary aim was to evaluate whether prevalent type 2 diabetes (T2D) modifies the effects of omega-3 supplementation on heart failure (HF) hospitalization. The secondary aim was to examine if race modifies the effects of omega-3 supplements on heart failure (HF) risk.
It is unclear whether race and type 2 diabetes (T2D) modify the effects of omega-3 supplementation on the incidence of HF. In this ancillary study of the parent VITAL (Vitamin D and Omega-3 Trial)—a completed randomized trial testing the efficacy of vitamin D and omega-3 fatty acids on cardiovascular diseases and cancer, we assessed the role of type 2 diabetes (T2D) and race on the effects of omega-3 supplements on the incidence of heart failure (HF) hospitalization (adjudicated by a review of medical records and supplemented with a query of Centers for Medicare and Medicaid Services data).
The results of the study are:
- When omega-3 supplements were compared with placebo, the HR for first HF hospitalization was 0.69 in participants with prevalent type 2 diabetes (T2D) and 1.09 in those without type 2 diabetes (T2D)
- Furthermore, prevalent type 2 diabetes (T2D) modified the effects of omega-3 fatty acids on the incidence of recurrent heart failure (HF) hospitalization
- In their secondary analysis, omega-3 supplementation reduced recurrent heart failure hospitalization only in Black participants
Thus, the data show beneficial effects of omega-3 fatty acid supplements on the incidence of heart failure (HF) hospitalization in participants with type 2 diabetes (T2D) but not in those without type 2 diabetes (T2D), and such benefit appeared to be stronger in Black participants with type 2 diabetes (T2D).
