Background Dietary micronutrient deficiencies have been shown to predict event-free survival in other countries but have not been examined in patients with heart failure living in the United States. The purpose of this study was to determine whether number of dietary micronutrient deficiencies in patients with heart failure was associated with shorter event-free survival, defined as a combined end point of all-cause hospitalization and death. Methods and Results Four-day food diaries were collected from 246 patients with heart failure (age: 61.
View Article and Find Full Text PDFBackground: Vitamin C deficiency is prevalent in adults with heart failure (HF). Little is known about the relationship of dietary vitamin C deficiency with health outcomes in adults with HF.
Objective: The study's aim was to determine the relationships of vitamin C deficiency measured at baseline with health-related quality of life (HRQOL) and cardiac event-free survival in patients with HF measured 1 year later.
Background: Low vitamin D intake and poor sleep quality are independently associated with cognitive dysfunction in healthy older adults. However, the relationships among vitamin D intake, sleep quality, and cognitive dysfunction are unknown in older adults with heart failure (HF).
Purpose: The aim of this study was to determine the relationships of vitamin D intake and sleep quality with cognitive dysfunction in older adults with HF.
Background: Heart failure is a chronic, burdensome condition with higher re-hospitalization rates in African Americans than Whites. Higher dietary antioxidant intake is associated with lower oxidative stress and improved endothelial function. Lower dietary antioxidant intake in African Americans may play a role in the re-hospitalization disparity between African American and White patients with heart failure.
View Article and Find Full Text PDFBackground: Depressive symptoms and vitamin D deficiency predict cardiac events in heart failure patients, but whether vitamin D supplements are associated with depressive symptoms and cardiac events in heart failure patients remains unknown.
Purpose: The purpose of this study was to compare the association of vitamin D supplement use with depressive symptoms and cardiac events in heart failure patients with mild or moderate to severe depressive symptoms.
Methods: A total of 177 heart failure patients with depressive symptoms (Patient Health Questionnaire-9 score ≥5) completed a three-day food diary to determine dietary vitamin D deficiency.
Background: Vitamin C is related to lower levels of high-sensitivity C-reactive protein (hsCRP), an inflammatory biomarker that predicts cardiovascular disease. Whether vitamin C deficiency is associated with hsCRP and cardiac events in heart failure (HF) patients has not been examined.
Purpose: The aim of this study is to determine the relationships among vitamin C intake, serum levels of hsCRP, and cardiac events.
Background: Factors that precipitate hospitalization for exacerbation of heart failure provide targets for intervention to prevent hospitalizations.
Objectives: To describe demographic, clinical, behavioral, and psychosocial factors that precipitate admission for exacerbation of heart failure and assess the relationships between precipitating factors and delay before hospitalization, and between delay time and length of hospital stay.
Methods: All admissions in 12 full months to a tertiary medical center were reviewed if the patient had a discharge code related to heart failure.
Background: Poor sleep quality is common and is associated with poor quality of life and health status in patients with heart failure. However, few investigators have focused on the impact of impaired sleep quality on survival in heart failure.
Objective: To examine whether self-reported sleep quality is associated with prognosis in patients with heart failure.
Background: Most clinicians rely on patients' self-report of following a low-sodium diet to determine adherence of patients with heart failure (HF). Whether self-reported adherence to a low-sodium diet is associated with cardiac event-free survival is unclear.
Purposes: To determine (1) whether self-reported is concordant with adherence to a low-sodium diet measured by food diaries and 24-hour urinary sodium excretion and (2) whether self-reported adherence to a low-sodium diet predicts cardiac event-free survival.
Background: Low vitamin D and depressive symptoms are associated with inflammation activation that predicts cardiovascular disease. Little is known about the relationships among vitamin D intake, depressive symptoms, and cardiac events in heart failure (HF).
Purpose: The aim of this study is to determine the relationships among vitamin D deficiency, depressive symptoms, and cardiac events.
Micronutrient Deficiency Independently Predicts Adverse Health Outcomes in Patients With Heart Failure.

Background: Despite growing evidence on the important role of micronutrients in prognosis of heart failure (HF), there has been limited research that micronutrient deficiency predicts health outcomes in patients with HF.
Purpose: The aim of this study was to determine whether micronutrient deficiency independently predicts adverse health outcomes.
Methods: A total of 113 consecutive outpatients with HF completed a 3-day food diary to measure intake of 15 micronutrients.
Background: Depressive symptoms and malnutrition independently predict cardiac events in heart failure (HF) patients. However, the relationships among depressive symptoms, nutritional intake, and cardiac event-free survival have not been examined.
Methods And Results: A total of 232 patients with HF completed the Patient Health Questionnaire 9 (PHQ-9) to measure depressive symptoms and a 3-day food diary to determine the number of micronutrient deficiencies.
Background: Type D personality is associated with medication non-adherence. Both Type D personality and non-adherence are predictors of poor outcomes. Self-efficacy, which is modifiable, is also associated with medication adherence.
View Article and Find Full Text PDFBackground: Depressive symptoms are predictors of shorter cardiac event-free survival, whereas increased body mass index (BMI) is associated with longer cardiac event-free survival in patients with heart failure (HF). However, the impact of BMI on the link between depressive symptoms and cardiac event-free survival is unexplored. The purpose of this study was to determine whether the relationship between depressive symptoms and cardiac event-free survival differs among HF patients stratified by BMI tertiles.
View Article and Find Full Text PDFBackground: Symptom monitoring is considered the first step toward self-care management (actions to manage altered symptom status) to avert worsening heart failure (HF). However, empirical evidence demonstrating that symptom monitoring leads to adequate self-care management is lacking. We examined the relationship of adherence to regular symptom monitoring with adequate self-care management in HF patients.
View Article and Find Full Text PDFBackground: Despite a growing recognition that a strict low sodium diet may not be warranted in compensated heart failure (HF) patients, the link between sodium restriction below 2 g/day and health outcomes is unknown in patients at different levels of HF severity.
Purpose: The purpose of this study was to compare differences in event-free survival among patients with <2 g/day, 2-3 g/day, or >3 g/day sodium intake stratified by New York Heart Association (NYHA) class.
Method: A total of 244 patients with HF completed a four-day food diary to measure daily sodium intake.
Background: Patients with heart failure (HF) commonly have unintentional weight loss, depressive symptoms, and elevated levels of high-sensitivity C-reactive protein (hsCRP). Each of these variables has been independently associated with shorter cardiac event-free survival. However, little data exist on the relationships of unintentional weight loss, hsCRP level, and depressive symptoms to cardiac event-free survival.
View Article and Find Full Text PDFBackground: The antioxidant lycopene may be beneficial for patients with heart failure (HF). Processed tomato products are a major source of lycopene, although they are also high in sodium. Increased sodium intake may counter the positive antioxidant effect of lycopene.
View Article and Find Full Text PDFBackground: The most desirable outcome in heart failure (HF) management is to improve health-related quality of life (HRQoL) as a patient-centred health outcome. Nutrition is assumed to be important in HF management, whereas there is little evidence that nutritional risk affects HRQoL, except for sodium.
Purpose: We aimed to determine whether nutritional risk is associated with worse HRQoL after controlling for daily sodium intake.
The purposes of this study were to explore the prevalence of Type D personality and the impact of Type D personality (the combination of negative affectivity and social inhibition) on health-related quality of life (HRQOL) in end-stage renal disease (ESRD) patients and to determine whether this link of Type D personality to HRQOL is mediated by depressive symptoms. Patients (n = 144) from an outpatient nephrology clinic of a university hospital participated in this cross-sectional study. The prevalence of Type D personality using Type D Personality Scale-14 was 26%.
