Filter by:Background and objectives Heart failure is a leading cause of morbidity and mortality worldwide and it is a major cause of emergency department access for cardiovascular disease patients. Aim of this study is to identify the markers, based on short-term temporal repolarization dispersion, capable to individuate decompensated chronic heart failure (CHF) patients at high mortality risk. Method: We will obtain the following variables from ECG monitor, via mobile phone, during 5-minute recordings in decompensated CHF patients: RR, QT end (QTe), QT peak (QTp) and T peak to T end (Te) and we calculated mean, standard deviation (SD) and normalized index (N).
The present study will recruit 40 symptomatic heart failure patients with left ventricular ejection fraction (LVEF) below 35% and complete left bundle branch block(QRSd≥130 ms). Each patient was randomized to either left bundle branch pacing(LBBP) or biventricular pacing(BivP) and was followed up for at least 6 months. The objective is to compare the effects of LBBP and BivP on cardiac resynchronization in the treatment of heart failure by measurable clinical parameters.
Medtronic is sponsoring the Apogee International registry to further confirm safety and efficacy of the HVAD™ System when used as intended, in "real world" clinical practice and to enhance scientific understanding of the implant procedure, optimized blood pressure management, anticoagulation/ antiplatelet therapies, logfile analysis and acoustic spectrum analysis in patients receiving a Medtronic HeartWare™ HVAD™ for bridge to transplant and destination therapy indications.
This study characterizes heart failure patients who attended the University Hospital Würzburg. The primary aim is a better understanding of the relationships and differences between the subgroups HFrEF (EF < 40%), HFmrEF (EF 40-49%), and HFpEF (EF>50%), contributing to an improved diagnosis, prognosis and therapy of patients with heart failure.
Heart failure (HF) is currently considered a common pathology, with 15 million adults in Europe and 26 million worldwide. The American Heart Association (AHA) estimates that their number will increase by 25% by 2030. In France, HF affects more than one million people. Because of the repeated hospitalizations of this disease, it is considered a costly pathology and with a high mortality rate (23.000 deaths per year in France). Moreover, HF is a severe pathology that affects the quality of life of patients and their families. Treatment and medical follow-up are required. A cardiac rehabilitation program is also a primary indication according to the latest recommendations and repositories in Cardiology. Various studies show that "Interval Training" exercise program improves VO2 peak compared to a "continuous" program, which constitutes a major prognostic factor in the population of heart failure. However, it is sometimes a difficult program to offer to more deconditioned patients as it requires reaching powers around 80% - 95% of its maximum exertion capacity. So, a variant of the interval training is offered, called Progressive Interval Training (PIT), based on the same model as the conventional interval training (CIT), but with an increasing power and breathing threshold, so that the patient can adapt gradually. The hypothesis is that PIT could improve VO2 peak better than CIT in cardiac rehabilitation program. Therefore, study the benefits of PIT training to improve the conditioning and quality of life of patients with chronic heart failure will be studied.
Health literacy (HL) is the ability to access, understand, evaluate and apply information in order to communicate with health professionals and understand health instructions but also, promote, maintain and improve health throughout life. Health literacy is known as a health determinant. An association has been shown between low health literacy and low health outcomes such as increased number of unscheduled hospitalization or emergency visits, low medication adherence and poor health status. These have been particularly demonstrated with cardiovascular diseases, which combine risk factors (emergency hospitalization, reduction in the length of hospital stays, and complex secondary preventive drug treatments). Despite many scientific international literature about health literacy and health outcomes, no information is available in France on the prevalence of low health literacy level of patients, notably cardiovascular patients. The investigating team's hypothesis is that knowing the prevalence of low HL levels in cardiovascular patients would help to better tailored a communication intervention dedicated to the needs of these low-HL patients with the final aim of increasing their adhesion to preventive drugs and behavioural recommendations. The first aim of the present study is to estimate the prevalence of low HL level among patients discharged after acute myocardial infarction or acute decompensation of chronic heart failure. Secondary aims are to assess factors associated with the level of HL and identify barriers and facilitators of low HL patients to understand medical information on their disease. The results of this study will guide the design of the intervention of an interventional study on HL of cardiovascular patients.
Study is conducted to assess the prevalence and structure of comorbidity among patients undergoing abdominal surgery and produce the stratification of the risk of postoperative complications by identifying independent predictors for its development.
The main objective of the study is to determine if a diuretic adaptation protocol in the decompensation of chronic heart failure is more effective but also safer than the current non-protocolized practice.
This study recruited patients diagnosed with heart failure by cardiologists and cardiac outpatients whose cardiac functions were graded from 1 to 4 according to the New York Heart Association as the study participants. The participants were provided active nutrition intervention including diet optimization,specific recommendations and nutritional supplement prescriptions in cases in which nutritional goals were not reached.In addition, this study offered advice by referencing lifestyle change advice provided by the American Heart Association for patients with heart failure. The Mini Nutritional Assessment Short-Form was used to assess malnutrition indicator values. The participant water, nutrient (i.e., carbohydrates, protein, and fat), and calorie intake data were collected using their recollection of their dietary intake and food intake frequency over a 24-hour dietary recall. The amount of fluid and sodium administered was provided according to the cardiac function grades indicated by the New York Heart Association.In addition, dietary assessments and nutritional advice were offered on the basis of the patients' conditions (i.e., age, activity, and comorbidity). Finally, instrumental activities of daily living, EQ-5D (an instrument for measuring quality of life), grip performance, and 6-minute walk test data were utilized to analyze the changes in the participants before and after intervention, identifying the correlation between using nutrition education as an intervention measure and improvement in the participants' nutritional status, quality of life, and self-care behavior.
It has been shown retrospectively that participation and even the willingness improves the survival of patients after myocardial infarction or heart failure. We aimed to prospectively analyse the role of participation in cardiology trials on the survival of patients in a high volumen tertiary center.
