Cardiac rehabilitation (CR) is strongly recommended for patients with coronary heart disease. However, patient enrollment and completion of cardiac rehabilitation is low. This study will examine if a mobile phone intervention that uses a text messaging program can successfully promote participation in cardiac rehabilitation.
Purpose. The aim of this study is to evaluate whether lung ultrasound, in addition to physical examination, leads to a reduction of the admission rate for acute decompensated heart failure of patients with chronic heart failure (HF) followed in the outpatients heart failure clinic. Methods. This is a prospective randomized study. The planned sample size consists of 440 patients with chronic HF. The inclusion criteria are: (1) male and female aged between 18 and 90 years (2) signed written informed consent (3) history of HF for at least six months, (4) left ventricular ejection fraction < 45%, (5) adequate medical therapy for HF for at least two months. The exclusion criteria are: (1) concomitant enrollment in other clinical studies, or treatment with experimental drugs or devices within 30 days of clinical assessment, (2) inability to undergo to the planned follow-up and procedures (3) documented pulmonary infections (3) interstitial lung disease and class 4 chronic obstructive pulmonary disease according to GOLD classification. Patients are randomized in two groups: group A, patients undergoing to lung ultrasound and physical examination; and group B, patients undergoing to physical examination only. Patients are evaluated at baseline and after three months with medical history, Quality of Life test, physical examination, blood sample for hematochemical (creatinine, electrolytes, BNP/NTpro-BNP). The diuretic therapy is then optimized according to the presence and severity of B-lines in group A and physical examination in group B. Only patients enrolled in group A undergo to a lung ultrasound examination to assess the extent of pulmonary congestion, through its evidence of B-lines. B-lines originate from the contrast between air-filled structures and water-thickened pulmonary interlobular septa. This leads to linear echogenic vertical artefacts that spread from the pleural layers downwards in the screen. The ultrasound examination is performed with a handheld echocardiography device. The physician carries out a scan of the pulmonary fields, from basal towards mid and apical fields, through the midaxillary line while the patient lies supine. The quantification of B-lines is performed according to their extent over the lung fields. All the information are recorded in dedicated forms. The results are evaluated according to the following criteria. The primary end-point is a significant reduction of hospitalizations for acute decompensated HF in group A during the follow-up period. The secondary end-points are changes of NT-proBNP values, quality of life test (QLT) score and cardiac mortality.
Cardiac Resynchronisation Therapy (CRT) is a specialist pacemaker procedure that aims to improve the efficiency of the heartbeat. This treatment is used routinely in patients with heart failure and a delay in electrical conduction across the heart seen on the surface ECG (heart tracing). Also CRT has been seen to improve some heart failure patients with a normal electrical conduction (seen on the ECG as a narrow QRS complex). The investigators aim to see if cardiac MRI can be used to select patients with normal electrical conduction for CRT, therefore expanding the number of people who would stand to benefit from this treatment.
This study is designed to demonstrate feasibility of study conduct and that acceptable adherence to adaptive servo-ventilation (ASV) therapy can be achieved in recently hospitalized HFpEF patients with moderate to severe sleep apnea. All subjects meeting the criteria will receive ASV therapy.
The main objective is to evaluate the pronostic value of endothelial dysfonction in acute heart failure on a combined criteria associating cardiovascular mortality, nex hospitalisation for decompensated heart failure, cardiac graft or ventricular assistance 2 month and 1 year before acute heart failure.
The study is designed to substantiate the efficacy of Cardiac Contractility Modulation (CCM) in the heart failure population with ejection fraction ranging between 25 and 45%. The study is designed in an adaptive manner to ensure proper statistical significance and power of the primary efficacy evaluation.
A single-center, prospective, non-randomized, clinical and first-in-human study. Each patient will be studied during a single treatment session of ten hours. The device will be connected to an existing, standard PD catheter that the patient will be using routinely prior to the study (i.e. a peritoneal dialysis catheter will not be specifically inserted for the study). The patient will be hospitalized for observation during the test day and during the night following the study session. Ultrafiltration volume, dialysate glucose concentrations, blood glucose concentrations as well the patient's acceptability and tolerance of the wearable device will be evaluated.
Peri-menopausal women will be randomized to hormone replacement therapy or placebo for 12 weeks to determine if markers of systolic and diastolic function change by echocardiography as well as laboratory markers of heart failure, including b-type natriuretic peptide (BNP).
This is a multicenter, randomized, double-blind, crossover, placebo-controlled, Phase II clinical study to evaluate the effect of serelaxin versus placebo (both in addition to SoC) on the release of hs-cTnI, in patients with CHF after an exercise testing session.
The purpose of this study is to evaluate whether vepoloxamer can provide a blood chemical marker and functional benefit to damaged heart muscle cells. This will be evaluated by measurement of blood-based laboratory markers, exercise tolerance, and echocardiograms. In addition, the safety and blood levels of vepoloxamer in subjects with chronic heart failure will be evaluated.
