Filter by:A growing interest in monitoring cardiac output (CO) non-invasively has emerged, however its determination has been difficult using the standard approaches. The aim of the study is to evaluate the accuracy and precision of pulse contour analysis (PCA) as compared to cardiac magnetic resonance imaging (CMR).
To evaluate the safety and effectiveness of the ALEX stent in a real-world setting of percutaneous coronary interventions in patients with coronary heart disease.
Humidified high flow nasal prong oxygen therapy is a method for providing oxygen and CPAP. The delivery of high flows decreases dilution of the inhaled oxygen and, by matching patient's peak flow, allows accurate delivery of the set FiO2 throughout the whole inspiratory phase. In addition, a flow-dependent effect of continuous positive airway pressure, possibly due to an air entrainment mechanism, has been documented in healthy volunteers and in patients with COPD. The investigators working hypothesis is that the use of post-extubation CPAP delivered via nasal cannulae in infants less than 18 months, post-bypass surgery will have better PaCO2 values than infants extubated on to oxygen therapy.
The freedom of choice in medicine is based on the physician's ability to treat their patients with the best available therapy. The armamentarium for percutaneous intervention is frequently determined on the basis of subjective criteria and the experience of the interventional cardiologist. The evaluation of devices used in coronary intervention, especially angiography and its clinical outcomes, has rarely been investigated; the exceptions are studies on stents. Therefore, the freedom of choice for the interventional cardiologist has been challenged, especially because of cost restrictions. This way this study aims to assess the safety and efficacy of a device of a single brand in performing percutaneous transluminal coronary angioplasty (guide catheters, guidewires, balloons, and stents) in selected patients.
This study is dedicated to determination of the long term effectiveness of coronary heart disease (CHD) treatments - cardiac shock wave therapy (CSWT) in comparison with other kinds of medical and surgical treatment. For that purpose the investigators will observe the patients with CHD who enrolled in this study in their routine course of treatment. But the investigators will not interfere with the patient treatment. Each participant will be followed-up for five years. The collected data will allow to determine if the particular method, CSWT, could really make any additional contribution to the more traditional methods of CHD treatment and if the CSWT is only temporarily effective or could exert the long term effect as well.
The aim of the Atahualpa project is to evaluate the cardiovascular (CVH) status of the inhabitants of a rural village of coastal Ecuador as well as to determine the prevalence and retrospective incidence of stroke and ischemic heart disease. The protocol may be used as a pilot for large-scale studies attempting to evaluate the CVH of rural or even urban centers of Latin America, to implement cost-effective strategies directed to reduce the burden of stroke and cardiovascular diseases in the population at large.
The aims of this prospective, observational study are to assess the current use of depression care in Coronary Heart Disease (CHD) patients, and to provide estimates for the resources needed to implement guideline-oriented depression health care acceptable to CHD patients with comorbid depression.
The objective of this clinical trial is to evaluate whether an anti-inflammatory medication, pentoxifylline, reduces depressive symptoms and improves artery function. Participants in this trial will be older primary care patients (60 years and up) who are depressed but do not have a history of cardiovascular disease. Half of these patients will receive pentoxifylline, and half will receive placebo. In addition, participants in both arms will receive an evidence-based psychological treatment called Beating the Blues®, which is a computerized, cognitive behavioral treatment program for depression. The investigators will use questionnaires to assess change in depressive symptoms and an ultrasound test to measure change in artery function from pre- to post-treatment. It is hypothesized that patients who receive pentoxifylline will show greater improvements in both depression and artery function than patients who receive placebo.
Coronary heart disease (CHD) pose a serious health threaten to population. Optimal revascularization strategy in multiple vessel coronary artery disease patients remains a subject of debate between interventional cardiologists and surgeons. Knowledge about the real-life revascularization pattern and outcomes in China is limited. By consecutively recruiting three vessel coronary heart disease patients in 25 geographically representative highest-rank hospitals, this study will examine revascularization strategy, and various real-life factors, that may affect patients lone-term recovery. Practical guidelines, appropriateness criteria and quality evaluative system for revascularization strategy will be established based on the findings, to improve patients outcomes in future finally.
The CoreValve ADVANCE-II Study is a best practices investigation of patients implanted with the Medtronic CoreValve bioprosthesis.
