Filter by:The ability and timely selection of severe heart failure (HF) patients for cardiac transplantation and advanced HF therapy is challenging. Peak VO2 by cardiopulmonary exercise test (CPET) was used for transplant listing. This study aimed to reassess the prognostic significance of peak VO2 and to compare that with the Heart Failure Survival Score in the current optimized novel guideline-directed medical therapy (GDMT).
A quasi-experimental and comparative study will be conducted in two different geographical areas (Europe-France and Africa-Cameroon) on a period of 18 months. All eligible adults aged 50 years and older presenting to one of the investigative centers (for HIV care) will be included in the study. The patients will be randomized in two parallel groups according to the 1:1 ratio, namely a control group A where patients continue the usual HIV management, and an intervention group B where in addition to the usual HIV management, patients will benefit from an adapted physical activity (APA) program for three months. An evaluation of heart rate variability, response to current treatment, gut microbiota profile and quality of life will be performed at the end of the APA session. Comparison between control group A and intervention group B will be performed. The acceptability of this program will also be evaluated.
Background: In non-invasive cardiopulmonary exercise testing (CPET), oxygen pulse (O2P) is defined as oxygen uptake divided by heart rate and is equal to the product of stroke volume and oxygen extraction by cells. As per, the O2P indicates the capability of oxygen consumption of whole body tissues and cells per heart beat. During exercise, the O2P changes can be deemed as the stroke volume changes as the oxygen extraction by muscle cells are normal. Hence, CPET-O2P can be non-invasively and continuously used to monitor the stroke volume changes during exercise. O2P value (i.e., % of predicted) is related to the severity and prognosis of heart failure and to the severity of constraint of the heart caused by exercise-induced hyperinflation or air trapping in patients with chronic obstructive pulmonary disease (COPD). However, O2P plateau pattern is not uncommonly encountered in the daily practice. Hypothesis and aims: O2P patterns during incremental exercise are seldom investigated although they have been hypothesized that the plateau or decreasing patterns are related to myocardial failure or ischemia. In this proposal, the O2P patterns are to be thoroughly investigated: (1) the patterns in norms, patients with heart failure and COPD, (2) the relationship between the O2P pattern and cardiac function and/or myocardial ischemia in patients with heart failure and COPD. As yet there are no relative reports on the O2P pattern and its possible mechanisms in the literature, the results of the proposal might tremendously impact the interpretation strategy of CPET reports. Methods: Multidisciplinary, prospective, comparative cross-sectional study is designed. Subjects aged from 40-85 years with the BMI of 18-28kg/m2 are to be enrolled: sample sizes of the norms, heart failure and COPD groups are 10, 20, and 20, respectively, equally distributed in two years. The definitions of COPD and heart failure with NYHA class I-III are according to the GOLD and ESC guidelines, respectively。All the three groups undergo CPET-NIRS, echocardiography, and the first pass and myocardial perfusion studies using Tc-99. The primary measurements are the O2P patterns and the cardiac function measured with echocardiography, the first pass and myocardial perfusion studies and air trapping in the lungs.。 Statistical analysis: For normal continuous data, t-test or ANOVA is used. For non-normal data, the Mann-Whitney test is used. The chi-square test or Fisher's exact test is used to compare the proportion of categorical variables between the two groups. A p value of less than .05 is considered to be statistically significant. Statistical procedures are performed using the SAS software package version 9.3.
Left ventricular failure (LVF) is a common cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This association is frequently underestimated with regard to the difficulty of clinical diagnosis . The investigators expect that the application of pressure support under NIV could be useful in this issue.
Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). On May 5, 2020, the US Food and Drug Administration (FDA) announced the approval of dapagliflozin for heart failure with reduced ejection fraction (HFrEF), regardless of whether the patient has diabetes. Subsequently, there have been additional approvals for this indication by regulatory authorities across the globe." Real-world observational data are necessary to describe dapagliflozin use in real-world settings with detailed clinical data on heart failure symptoms, outcomes, and HRQoL
China National Heart Failure Registration Study (CN-HF) is a nationwide, hospital-based, multicentre, prospective registry study sponsored by Ministry of Science and Technology of the People's Republic of China. It is aimed to understand the etiology, clinical features and treatments of in-hospital HF patients in China [3]. At present, there are few studies to describe the clinical outcomes of HF patients with different sK levels in China. Utilizing the CN-HF database, this study is aimed to describe the sK levels of hospitalized HF patients and its impact to the clinical outcomes of patients.
The AWARENESS HF-PD is a cross-sectional, multicenter, survey-based study. Cases who were admitted to the outpatient clinic and hospitalized with the diagnosis of Heart Failure (Acute and Chronic) will be included in the study.
ADAPTATION HF is a prospective, observational, cross-sectional, multicenter, survey-based study. Patients who applied to the cardiology outpatient clinic with a preliminary diagnosis of HF or were hospitalized for HF and had a diagnosis of HF for at least 6 months will be included in the study.
There is an increasing interest in the use of metformin in CV diseases and there is an increasing interest in studying its potential new roles in heart failure patients. There were some concerns related to the safety of metformin in such diabetic patients due to the risk of lactic acidosis. However, recent studies showed that metformin was safe or even beneficial in HF patients. We hypothesized that metformin might improve morbidity, mortality, cardiac function, and HR-QoL in non-diabetic patients with HFrEF.
This study is a virtual, remote, decentralized pragmatic clinical trial comparing the efficacy of medically tailored meals alone or medically tailored meals with remote nutritional counseling compared with usual standard of care in adults with a targeted, nutrition-sensitive chronic medical condition (heart failure, diabetes mellitus, chronic kidney disease).
