Filter by:This study aims to gather information to what extent patients follow the treatment regimen of low-dose aspirin for primary and secondary prevention of diseases of the heart and blood vessels. Researcher will collect information about the percentage of time a patient has access to the medication, how long patients continue with the medication and of the proportion of patients who switch from dual-antiplatelet therapy (including low-dose aspirin) to a single antiplatelet therapy. The study will make use of secondary healthcare data sources converted in to Observational Medical Outcomes Partnership (OMOP) common data model within the Observational Health Data Sciences and Informatics (OHDSI) network.
Microvascular angina (MVA) is caused by abnormalities of the small vessels in the heart. Endothelin is a small chemical that circulates and accumulates in the blood vessel walls, causing them to narrow or go into spasm and thicken in the longer term especially as levels of endothelin increase. As a result, patients experience pain, psychological burden and an inability to carry out daily activities. Originally developed by AstraZeneca for cancer treatment, prior research has confirmed that Zibotentan relaxes the small blood vessels of patients with MVA which lends support to the idea that Zibotentan may bring some benefits to patients with MVA. This trial therefore proposes to look into re-purposing zibotentan as a new treatment for patients with MVA. The primary objective is to assess the effect of add-on treatment with Zibotentan to treadmill exercise times in adult patients with MVA and impaired exercise intolerance. Zibotentan could provide a new treatment pathway for patients, as well as be made available to the NHS at substantially lower cost than the currently used medications. The trial aims to initially invite approx. 356 participants for genetic testing. A minimum of 100 participants will go forward into the main study, receiving either 10mg zibotentan or a dummy matched tablet (placebo) daily over two 12 weeks periods of each, completing their final visit at week 34. The study assessments will involve a health check at each visit, including information on the patient's wellbeing, blood tests, some quality of life questionnaires, and an exercise test. Participants will also have the option to consent to additional sub-study cardiovascular MRI scanning. Finally, participants will be invited to provide consent for long-term follow-up (maximum 20 years) of their electronic medical records (no additional patient contact).
This study, taking stable angina pectoris as a research carrier, aims to explore the preventive value of acupoint sensitization by conducting a double-blind multi-center randomized controlled trial to compare the effect of stimulating acupoints with different sensitivity on the prevention of angina pectoris. After the inclusion of eligible patients, the pressure-pain threshold of disease-related acupoints will be detected by using Von Frey detector. Then, the patients will be randomly divided into experimental group and control group. The patients in experimental group will be given acupoints pressure on the five acupoints with the lowest pressure-pain threshold, while the patients in control group will be given acupoints pressure on the five acupoints with the five acupoints with the highest pressure-pain threshold. The two groups will be treated with acupoints pressure 12 times within 4 weeks. The patients will be evaluated three times at baseline, the end of treatment and four weeks after the end of treatment respectively, including angina attack frequency, CCS classification and SAQ score.
early identification of vulnerable plaques by remodeling index prior to rupture and development of acute event is of considerable importance especially by a reliable non-invasive method as CT coronary angiography.
This study was performed to investigate the anatomical attributes that determine myocardial territory of diagonal branches and to develop a prediction model for clinically relevant branches using myocardial perfusion imaging (MPI) and coronary CT angiography (CCTA).
Stable angina is a cardiac pathology that adversely affects the quality of life of the patient, which develops as a result of narrowing of the coronary vessels developing in atherosclerotic ground and / or impaired oxygen supply-need balance. Studies widely investigated the effects of exercise training in patients with stable angina. No study investigated the effects of inspiratory muscle training in patients with stable angina.Investigators aimed to investigate the effects of inspiratory muscle training on aerobic exercise capacity, quality of life, depression, peripheral and respiratory (MIP, MEP) muscle strength, pulmonary function, dyspnea, fatigue in stable angina patients.
This is a randomized pharmacological study evaluating the effects of ivabradine in patients with residual angina after PCI. The role of ivabradine in patients with angina, without systolic dysfunction, is not yet clear. The investigators performed in all patients an echostress to evaluate the effects of therapy with ivabradine after 30 days in terms of exercise tolerance and diastolic function.
The goal of the ACCURACY study is to assess the differences, if any, in FFR measurements made by the OptoWire Deux FFR guidewire by comparison of simultaneous data of two different OptoWire DeuxTM guidewires (group 1). In addition, the investigators will compare (group 2) the FFR measurements obtained from an OptoWire Deux FFR guidewire and compare it to the FFR measurement by a VERRATA-TM guidewire to assess coronary stenosis in the routine clinical practice.
The study included 511 patients who underwent PCI because of angina during 2010-2011 at three Korean hospitals. Clopidogrel-naïve patients received either a loading dose (LD; 600 mg at 2-24 h before the procedure) or routine maintenance therapy (75 mg/day for ≥5 days) plus either a 300-mg reload (RL) or only the maintenance dose (MD).
ORBITA-2 is a double blinded randomised placebo-controlled trial comparing the effects of coronary angioplasty versus placebo procedure on symptoms of stable angina without background anti-anginal therapy. Follow-up will be at 12 weeks.
