10,000 IU of Vitamin D daily for 6 months raised levels by 49 ng
Cardiovascular category starts with the following
- Overview Cardiovascular and vitamin D
- Hypertension and vitamin D
- Overview Metabolic Syndrome and vitamin D
- Overview Stroke and vitamin D
- Peripheral arterial disease risk is 1.5X higher if low vitamin D – meta-analysis March 2018
- Peripheral Arterial Disease 3.7 X more likely in diabetics with low vitamin D – June 2019
- Heart attack ICU costs cut in half by Vitamin D – Oct 2018
- Heart Failure and Vitamin D meta-analyses - 2016, 2019
- Cardiovascular death 1.5X more likely if less than 20 ng of Vitamin D – 22nd meta-analysis Nov 2019
- Vitamin D supplementation reduces many Cardiovascular Disease markers– meta-analysis July 2018
- Cardiovascular Prevention with Omega-3 (finally using high doses) – Sept 2019
- Higher Omega-3 index (4 to 8 percent) associated with 30 percent less risk of coronary disease (10 studies) July 2017
A poor Vitamin D Receptor can block Vitamin D in blood from getting to tissues
- Heart Failure 15X more likely if poor VDR, even if good level of vitamin D (China) – March 2019
- Coronary Artery Disease without diabetes 5 times more likely if VDR gene problems – meta-analysis May 2016
- Cholesterol is needed to produce both Vitamin D and Cortisol
- Overview Cholesterol and vitamin D
- Statins and vitamin D statins often reduce levels of vitamin D
- Statin side-effects are reduced by Vitamin D – US patent Application – April 2019
Note: Kansas City Cardiomyopathy Questionnaire ranges from 0 (worst, with poor chance of survival) to 100
Vitamin D status may influence heart failure (HF) patient outcomes by affecting b-type natriuretic peptide (BNP), parathyroid hormone (PTH), and enhancing cardiac contractility. Vitamin D deficiency is associated with morbidity and mortality in HF patients. The objective of this study was to determine if vitamin D3 at a comparatively high dose would replete 25-hydroxyvitamin D (25(OH)D) stores, improve BNP, PTH, cardiopulmonary function, reduce inflammatory markers, and improve quality of life (QOL) in HF patients.
This was a 6 month, parallel group, double-blind, placebo-controlled, single clinic center, randomized trial of supplemental vitamin D3 using a dose of 10,000 IU daily or placebo in 40 vitamin D deficient or insufficient (25(OH)D level ≤ 32 ng/ml) patients with stable New York Heart Association Class II-III HF in a specialty cardiology clinic. All variables were measured at baseline and 6 months. Values between the two treatment groups were assessed using Student's t-test or Mann-Whitney Test. Univariate analysis of covariance was conducted to adjust for variance in baseline 25(OH)D.
All results were adjusted for baseline 25(OH)D. The change in BNP from baseline was ∆ +30 ± 950 pg/ml for treatment vs. placebo ∆ +400 ± 1900 pg/ml, p = 0.003. 25(OH)D serum levels rose by 49 ± 32 ng/ml in the treatment group vs 4 ± 10 ng/ml in the placebo group, p < 0.001. PTH and exercise chronotropic response index improved in the treatment group vs placebo group, respectively, but both were attenuated by adjustment ( (∆-20 ± 20 pg/ml vs ∆ + 7 ± 53 pg/ml respectively (p = 0.01, adjusted p = 0.07)) and (∆ + 0.13 ± 0.26 vs. ∆-0.03 ± 02.9 respectively, p < 0.01, adjusted p = 0.17)). Other measured cardiopulmonary parameters remained unchanged. High sensitivity C-reactive protein (hsCRP) remained unchanged for women, but improved for men (∆-2 ± 4 treatment versus ∆2 ± 5 mg/L placebo, p = 0.05).
QOL scores, including composite overall and clinical summary scores significantly improved in treatment compared to placebo (∆ + 10 ± 15 versus -6 ± 15, p < 0.01 and ∆ + 8 ± 14 versus -8 ± 18, p = 0.01, respectively).
Repletion of 25(OH)D may improve QOL in HF patients and may help to normalize BNP, PTH, and hsCRP.
