Filter by:The purpose of this study is to demonstrate that the strength of agreement between single photon emission computed tomography (SPECT) imaging with regadenoson following inadequate exercise stress testing and SPECT imaging with regadenoson alone is not inferior to the strength of agreement between two sequential regadenoson SPECT images without exercise.
The main aim of this study will evaluate differences in serum levels of tryptase in study population. Will be selected a number of 350 patients hospitalized for coronary heart disease.
Physical rehabilitation is a key element in the treatment of patients with cardiovascular diseases, and recent evidence has shown that supervised exercise programmes can prevent cardiovascular events, improve physical function and quality of life. Individualized exercise prescription based on appropriate frequency, intensity and duration is recommended. Furthermore, recent studies have shown that physical cardiac exercise training can influence inflammation of the vessel wall and hence reduce development of arteriosclerosis in coronary vessels. In the literature are divergent conclusions on appropriate frequency and duration of physical rehabilitation programs in order to improve physical function and reduce arteriosclerosis. The purpose of this study is to investigate the efficacy of an optimized physical rehabilitation programme compared to a conventional programme on physical fitness, health related quality of life and vascular inflammation.
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 23 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 aim of the study is to evaluate platelet function variations according to the delay since last aspirin intake (12 vs 24 hours)in a population of diabetic patients with previous Coronary Artery Disease.
During cardiac displacement for off-pump coronary artery bypass(OPCAB) surgery, the presence of air underneath the displaced heart compromises the transgastric (TG) window for transoesophageal echocardiography(TOE). The investigators hypothesised that placing a saline-filled glove would enhance TG transmission of ultrasound and facilitate TOE imaging for monitoring left-ventricular regional wall motion (LV-RWM). For left circumflex coronary artery (LCX) grafting in OPCAB surgery (n=13), mid-oesophageal (ME) and TG TOE images are recorded before cardiac displacement (T control), after displacing and stabilising the heart (T-displaced), and after placing a saline bag (saline-filled surgical glove) underneath the displaced heart (T-saline bag). Following data are determined by integrated TG and ME TOE views (ME+TG) at T-control, T-displaced and T-saline bag: number of readable segments (NRS) in a 17-segment model; NRSs in basal and mid-TG short axis views; NRS in 5-LV segments of the LCX territory; the incidence of inadequate monitoring of LV-RWM (NRS < 14/16 except for the apex in 17-segment model).
In this study, typical cases of blood stasis syndrome of coronary heart disease are selected, by using microRNA chip, cDNA microarray and other bioinformatics technologies to filter and verify related miRNA and its target gene of Coronary Heart disease. Meanwhile, intervene by Xuesaitong soft capsules to investigate related miRNA and its target gene of Coronary Heart disease.
Personalized treatment approaches and antiplatelet drug choice have been proposed to optimize safety of coronary stenting by reducing heart attacks and repeat interventions while simultaneously minimizing adverse bleeding events. This study compares the efficacy of two laboratory guided treatment algorithms to personalize antiplatelet medication choice after coronary stenting
Registry of cilotax stent(Dual drug eluting stent) implantation for CAD patients
The purpose of this study is to demonstrate the safety and efficacy of the investigational BIOTRONIK PRO-Kinetic Energy stent in subjects with atherosclerotic disease of native coronary arteries.
