Background: Vitamin D deficiency has been associated with cardiovascular mortality and sudden cardiac death in heart failure patients. Vitamin D may influence parathyroid hormone, the renin-angiotensin axis, natriuretic peptide gene expression, cardiac contractility, and cardiopulmonary function. Heart Failure (HF) studies using vitamin D to date have typically not used adequate repletion doses. Objectives: The primary objectives of this research were to determine if vitamin D repletion over a six month period in New York Heart Association (NYHA) Class II-III HF patients would result in a change in neurohormonal markers, cardiopulmonary exercise parameters, circulating 25- hydroxyvitamin D, and quality of life. Methods: A randomized, double-blinded, placebo-controlled trial assessing adjunctive Vitamin D3 supplementation in the treatment of NYHA Class II-III HF patients was conducted. Patients received 10,000 International Units (IU) per day of vitamin D3 or placebo for 6 months. Inclusion Criteria: 1) 25-hydroxyvitamin D level ≤32 ng/ml 2) stable medical regimen for 3 months. Exclusion Criteria: 1) any clinically unstable medical disorder 2) supplementation of vitamin D3 or D2 of greater than or equal to 2,000 IU/day. Study endpoints were: 1) B-type Natriuretic Peptide (BNP), 2) cardiopulmonary exercise parameters using Shape HF, 3) 25-hydroxyvitamin D, 4) intact parathyroid hormone (PTH), and 5) quality of life with the Kansas City Cardiomyopathy Questionnaire (KCCQ). Statistical analysis included independent samples t-test and multivariate regression. Results: A total of 34 patients completed the study. When adjusted for baseline 25-hydroxyvitamin D, the difference between groups for BNP was significant ([[Unable to Display Character: &#8710;]]540 ±1928 pg/ml placebo vs [[Unable to Display Character: &#8710;]] 35 pg/ml ±1054 pg/ml treatment p=0.009). 25-hydroxyvitamin D was [[Unable to Display Character: &#8710;]]48.9 ±32 ng/ml treatment vs [[Unable to Display Character: &#8710;]]3.6 ± 9.4 ng/ml placebo, p<0.001 (mean 68 ng/ml treatment vs 23 ng/ml placebo). No toxicity was observed with treatment. PTH and exercise chronotropic response index trended towards improvement in the treatment group vs placebo group, respectively (([[Unable to Display Character: &#8710;]]-20 ±20 pg/ml vs [[Unable to Display Character: &#8710;]]7 ±54pg/ml (p=0.06)) and ([[Unable to Display Character: &#8710;]]0.13±0.26 versus [[Unable to Display Character: &#8710;]]-0.03 ± 0.23, p=0.12)). KCCQ quality of life total symptom ([[Unable to Display Character: &#8710;]]16 ±16 treatment vs [[Unable to Display Character: &#8710;]]-12 ±15 placebo, p< 0.001) and individual scores significantly improved from baseline in the treatment group. Conclusions: Preliminary results show that vitamin D3 treatment of 10,000 IU/day in heart failure patients is safe, results in adequate circulating 25-hydroxyvitamin D levels, and achieves improvement in surrogate endpoint markers of HF outcomes.

Background: Heart failure is a leading cardiac morbidity prevalent across the globe. Its incidence is rising in direct proportion to increasing longevity all over the world. Demographic variables are important predictors of quality of life, morbidity, rehospitalization, and mortality due to systolic heart failure. The objective of our study was to assess the association of demographic variables with quality of life of systolic heart failure in patients presenting at Cardiology Out Patient Department, Hayatabad Medical Complex, Peshawar. Our study aims to inform policy making as it highlights some important demographics factors associated with quality of life. Methods: A cross sectional method was employed in the study to examine systolic heart failure and its prevalence across various demographic variables such as age, gender, marital status, activity, number of children, education, employment status, and BMI at cardiology OPD of a medical teaching institution in Peshawar. Consecutive sampling was used and data were collected through a structured questionnaire from 368 Systolic Heart Failure patients. Data were analyzed using SPSS version 22. Results: We had 368 participants, a majority of whom (n=290; 78.8%), were in NYHA class III. The rest (n=78; 21.2%) were in class IV. Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to categorize quality of life into ‘Good’, ‘Moderate’ and ‘Poor’. Most participants were in the ‘poor’ category with MLHFQ scores >45 (n=193; 52.4%). Those who had scores between 25 -45 were categorized as ‘moderate’ (n=116; 31.5%), and participants who scored < 24 were categorized as having a ‘good’ quality of life (n=59; 16%). Reliability of tools was checked by Cronbach alpha which was 0.86 Conclusion: It was concluded that demographic variables have a significant effect on the overall morbidity of heart failure patients and heart failure related quality of life.

Background: The management of Heart Failure (HF) is the cornerstone for the appropriate therapy and the knowledge obtained concerning the disease is known to affect self-care behaviours. Aim: The aim was to test the association between self-care management, knowledge, self-efficacy for medication and quality of life in chronic HF patients.Material and Method: A cross-sectional study was conducted and four questionnaires were used: Atlanta Heart Failure Knowledge Test (AHFK), Minnesota Living with Heart Failure (HMLHFQ), Self-Efficacy for Appropriate Medication Use Scale (SEAMS), European Heart Failure Self-care Behaviour Scale (EHFScBS-9). Multiple linear regression analysis was performed to identify independently associated variables with study subscales.Results: The sample consisted of 122 Heart Failure patients (102 men-20 women) with mean age 67.1 years (SD=12.3). Scores on Fluid and sodium management, Physical activity and recognition of deteriorating symptoms were  significantly greater  as compared with scores on Adhering to recommendations (p<0.001), indicating that the needs concerning Adhering to recommendations were greater.  Linear regression analyses showed that score on knowledge-test and New York Heart Association (NYHA) class were predictive of medication adherence factors. Better knowledge was associated with better medication adherence, while worse scores were found in subjects with NYHA class III or IV as compared to those with NYHA class I or II. Additionally, Knowledge and years of Education were associated with Self-care behaviour factors (β=0.44, SE=0.08, p<0.001). Conclusions: Patients at a higher level of HF knowledge show better adherence to the Medication. Self-care behavior and life quality are improved.

Introduction The * Equal contributors. health-status of heart failure patients can be improved to some extent by disease self-management. One method of developing such skills is telephone-based health coaching. However, the effects of telephone-based health coaching remain inconclusive. The aim of this study was to evaluate the effects of telephone-based health coaching for people with heart failure. Methods A total sample of 7186 patients with various chronic diseases was randomly assigned to either the coaching or the control group. Then 184 patients with heart failure were selected by International Classification of Diseases (ICD)-10 code for subgroup analysis. Data were collected at 24 and 48 months after the beginning of the coaching. The primary outcome was change in quality of life. Secondary outcomes were changes in depression and anxiety, health-related control beliefs, control preference, health risk behaviour and health-related behaviours. Statistical analyses included a per-protocol evaluation, employing analysis of variance and analysis of covariance (ANCOVA) as well as Mann-Whitney U tests. Results Participants’ average age was 73 years (standard deviation (SD) = 9) and the majority were women (52.8%). In ANCOVA analyses there were no significant differences between groups for the change in quality of life (QoL). However, the coaching group reported a significantly higher level of physical activity ( p = 0.03), lower intake of non-prescribed drugs ( p = 0.04) and lower levels of stress ( p = 0.02) than the control group. Mann-Whitney U tests showed a different external locus of control ( p = 0.014), and higher reduction in unhealthy nutrition ( p = 0.019), physical inactivity ( p = 0.004) and stress ( p = 0.028). Discussion Our results suggest that telephone-based health coaching has no effect on QoL, anxiety and depression of heart failure patients, but helps in improving certain risk behaviours and changes the locus of control to be more externalised.
