Filter by:This study aims to evaluate the use of the chest pain choice (CPC) decision aid as a tool to facilitate discussion between the patient and his/her attending physician with regard to subsequent management plans. Patients aged 21 years and above with low-risk chest pain, as determined by the HEART score (HEART score 0-3), will be included. The investigator's hypothesis is that incorporating the Chest Pain Choice visual aid in shared decision making can help to reduce unnecessary admissions for low risk chest pain to the observation ward, as well as increase patient knowledge with regards to their own condition.
This study aim is to evaluate the additional effect of eicosapentaenoic acid and dose up effect of rosuvastatin for neoatherosclerosis in coronary artery disease patients.
The benefits of cardiac rehabilitation are well known. However, despite center based cardiac rehabilitation (CBCR) representing guideline-based care for patients with cardiovascular disease, most patients do not complete the maximum number of sessions allowed by third party insurance payers. As such, many patients may not be receiving the full clinical benefit ascribed to CR. This study will assess the efficacy of an innovative approach to CR delivery on attendance by combining both center-based and remote- or home-based CR sessions. The intervention group combines center-based CR and remote-/home-based CR and is tailored to the individual needs of each patient, accomplished with the assistance of an easy-to-access telecommunications methodology (telemedicine)
This study aims to evaluate the efficacy and safety of traditional Chinese medicine DaZhu Rhodiola Rosea Capsule for treatment of coronary artery disease by observing angina symptoms, exercise capacity, and quality of life.
The study is to evaluate efficacy and safety of low dose of ticagrelor therapy for Chinese unstable angina patients treated with non-urgent coronary stent implantation, to examine whether lower dose ticagrelor (45 mg twice-daily) is not inferior to standard dose (90 mg twice-daily) for the prevention of major adverse cardiovascular and cerebrovascular events, as well as will reduce the incidence of bleeding during long-term treatment.
The purpose of this study is to verify whether additional administration of Alirocumab exerts a stronger stabilizing effect on the vulnerable plaque in CAD, compared with statin alone administration in patients receiving PCI. Therefore, the change in maxLCBI (4 mm) of the coronary artery 9 months after administration by addition administration of Alirocumab is evaluated as the main evaluation item as compared with statin administration alone for patients who have CAD and received PCI. Also, change of plaque properties is compared with baseline and evaluated. This study is a single-center, randomized, open-label study, using alirocumab, rosuvastatin as test drugs. Based on the findings obtained in this study, it is possible to clarify the mechanism of stabilization of the plaque in a patient with coronary artery disease, which in turn suppresses the progress of plaque in coronary artery disease, resulting in primary or secondary There is a possibility that it can contribute to prevention.
Study aim : To compare a novel strategy of lesion preparation with noncompliant balloons before implantation of BVS. Hypothesis: Predilatation with non-compliant balloons could facilitate optimal deployment of BVS. By achieving good scaffold apposition a need for post-dilatation could be significantly reduced. This is expected to result in better short- and long-term outcomes.
This is a prospective cohort study to examine the efficacy of ESMR application in patients with refractory angina despite optimal medical therapy, not suitable for further PCI or CABG. Characteristics such as angina class scores (CCS class score), nitroglycerin consumption and hospitalization were compared at baseline and 1, 6 and 12 months after ESMR therapy. The effect on cardiac perfusion was assessed at 6 months.
In a cohort of symptomatic patients referred to coronary computed tomography angiography (CCTA), the investigators aim: 1. To investigate and compare the diagnostic precision of Rubidium Positron Emission Tomography (Rb PET) and 3 Tesla Cardiac Magnetic Resonance imaging (3T CMRI) in patients where CCTA does not exclude significant coronary artery disease (CAD) using invasive coronary angiography with fractional flow reserve (ICA-FFR) as reference standard. 2. To evaluate the diagnostic precision of quantitative flow ratio (QFR) and ICA-FFR in patients where CCTA does not exclude significant CAD using Rb PET and 3T CMRI as reference standard. 3. To show superiority for the CADScor®System compared to the Diamond-Forrester score in detection of CAD with CCTA and ICA quantitative coronary angiography (ICA-QCA) as reference standard. 4. To study the diagnostic accuracy of computed tomography fractional flow reserve (CT-FFR) in patients where CCTA does not exclude significant CAD with ICA-FFR as reference standard. 5. To identify and characterize genetic risk variants´ and circulating biomarkers´ importance in developing CAD. 6. To evaluate the bone mineral density in the hip and spine and correlate this to the degree of vascular calcification.
Angina in patients without obstructive coronary artery disease (CAD) is a clinical conundrum and patient management is heterogeneous. Hypothesis: Abnormal coronary function is common and clinically relevant in this population. Design: An observational cohort study and nested randomised controlled diagnostic strategy trial. Methods: 250 patients with known or suspected angina informed by validated questionnaires but without obstructive CAD (<70% stenosis) in an artery >=2.5 mm or structural heart disease, as revealed by CT coronary angiography (CTCA), will be invited to undergo coronary function testing (FFR, CFR, IMR; intra-coronary ACh) during invasive angiography. Patients will be randomised following angiography but before testing coronary function to disclosure of the coronary function test results or not. Treatment decisions by the attending cardiologist will be recorded before and after disclosure of results. Outcomes: Primary: The between-group difference in the reclassification rate of the initial diagnosis using logistic regression, adjusted for baseline factors associated with the likelihood of reclassification of the initial diagnosis. Secondary: Prevalence of microvascular or vasospastic angina; health status reflected by the EuroQol group 5-Dimensions (EQ-5D), Seattle Angina Questionnaire, Illness perception, treatment satisfaction questionnaires and functional status questionnaires; angina medication and adherence. Value: This research will provide new insights into the conundrum of angina in patients without obstructive CAD or structural heart disease.
