Filter by:This is a post-market, standard of care, real-world observational study to assess the clinical outcomes of the SYNERGY XLV (MEGATRON) Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) ≤ 28 mm in length (by visual estimate) in native coronary arteries ≥3.50 mm to ≤5.00 mm in diameter (by visual estimate). This Post Approval study is a cohort associated with the Evolve 4.5/5.0 (SYNERGY LV) Post Approval Study, which is registered under ClinicalTrials.gov ID: NCT03875651.
The study was a multicenter, two-arm, parallel, open label, prospective study intended for to compare effect of offline community hospital intervention on adherence to drugs and risk factors control in patients with stable coronary artery disease compared with tertiary A-level hospital WeChat-based intervention.
Infants with congenital heart disease (CHD) are usually born with a normal weight but develop malnutrition over time, and about 20-50% of these children are usually malnourished. Malnutrition in these patients is multifactorial. To compensate for the increased need for infants and children with CHD, an increase in their caloric intake has been suggested. However, these patients may not be able to receive enough to meet the increased needs and catch-up growth. One of the suggested solutions in these patients to compensate for inadequate food intake is to increase the caloric density of milk or formula. For this purpose, the use of special formulas with higher calorie density or enrichment of normal formula or breast milk using special enrichment formula could be suggested. In the present study, the effect of increasing calorie intake by increasing the concentration of normal formula in comparison with formula with standard concentration on weight gain and other anthropometric indices of CHD patients with malnutrition will be compared.
Coronary heart disease (CHD) is a leading cause of premature death in Canadian women. Women who suffer an acute coronary event are more likely than men to be physically inactive, have lower exercise capacity, and die in the next year. The standard cardiac rehabilitation (CR) programs do not meet women's needs. There is a need to address these issues to increase participation in CR. The main purpose of this project is to evaluate the effects of high-intensity interval training (HIIT) compared to moderate-intensity continuous exercise training (MICE) on exercise capacity and quality of life in women with CHD. Positive results of this study will fill the gap in knowledge in exercise training, levels of motivation, self-efficacy and enjoyment following HIIT vs. MICE in women with CHD.
A multicentre, post-marketing, observational trial in 450 patients, whose standard diagnostic workup for chronic coronary syndromes provided for Invasive Coronary Angiography (ICA). Medical records of a potential subject of the trial before their enrolment contain a good quality result of at least 128-slice CCTA performed up to 3 months before the elective ICA. CCTA should find at least one ≥50% stenosis in at least one big coronary artery of ≥ 2 mm diameter. At one hour before ICA in the latest the patient should have a resting Continuous Non-Invasive Blood Pressure (CNBP) taken with a certified device delivered by LifeFlow. The last criterion before including a patient in the final analysis is at least one significant (≥50%) stenosis in one or two coronary arteries of ≥ 2 mm diameter visually confirmed by ICA with a FFR measurement taken in these arteries. The data collection period will cover time from admission for the elective ICA to discharge from the hospital (evaluation of possible adverse events related to invasive procedures). After initial qualification of available data by the attending physician, selected patients will be asked for a consent to participation in the trial no later than upon admission for the elective ICA and before CNBP measurement.
The purpose of this study is to understand the impact of beta-blockers on physical function in older adults with heart failure. We will achieve this objective by conducting N-of-1 trials. N-of-1 trials are personalized experiments that test different treatment options in an individual patient.
Microcirculatory disturbance occurs most seriously during cardiopulmonary bypass (CPB) in cardiac surgery. If microvascular reactivity compensates for microcirculatory disturbance during CPB, tissue hypoxemia may be minimized. On the other hand, tissue hypoxemia may develop and lead to poor clinical outcomes. The primary aim of this study was to assess whether microvascular reactivity during CPB can predict major adverse events (MAE) within 30 days after cardiac surgery. This prospective, observational, single-center study was conducted on 115 patients who underwent elective on-pump cardiac surgery. The vascular occlusion test (VOT) with near-infrared spectroscopy was performed five times for each patient, before the induction of general anesthesia (baseline, T0), 30 min after the induction of general anesthesia (T1), 30 min after applying CPB (T2), 10 min after injection of protamine (T3), and after sternal closure (T4). Sequential Organ Failure Assessment (SOFA) and Acute Physiologic and Chronic Health Evaluation (APACHE) II scores and the length of ventilator care, intensive care unit stay, and hospital stay were recorded. Postoperative MAE within 30 days after surgery was also recorded.
In this study, we will test the feasibility of N-of-1 trials for deprescribing beta-blockers in patients with Heart Failure with Preserved Ejection Fraction. To achieve this objective we will conduct 16 4-period N-of-1 trials (on vs. off) and subsequently interview participants to better understand feasibility and pragmatism. The N-of-1 trials will be iteratively refined in real-time based on this feedback.
The purpose of this research is to investigate whether patients who previously had endoprosthesis surgery experience memory, thinking, or heart problems. It will also help determine how often these problems occur.
The study aims to examine how noradrenaline in combination with venous return influences the energy transmission from heart to central circulation and arteries - also called arterio-ventricular coupling.
