Filter by:Because of its availability, non-invasiveness, and high diagnostic performance, myocardial perfusion tomoscintigraphy has become a standard tool for the detection, characterization and monitoring of coronary artery disease. Standard analysis, based on the reversibility of regional myocardial hypoperfusion between stress (physiological or pharmacological) and rest, has good sensitivity and negative predictive value in the search for myocardial ischemia. However, two major obstacles persist. First, because of the relative nature of the normalization of cardiac activity, this approach may underestimate the extent of the damage, especially when the territory with the most activity is itself pathological. Thus myocardial perfusion scintigraphy can only detect 40 to 50% of tri-truncal patients. To overcome these disadvantages, several indexes have been proposed to improve the diagnostic performance of perfusion scintigraphy in multi-truncal patients based in particular on kinetic analysis. Secondly, the review does not provide any guarantee as to the quality and reproducibility of use of the coronal reserve during stress, in particular during submaximal stress tests and pharmacological stress, the latter being easily antagonized by xanthine derivatives contained in tea and coffee in particular (abstinence of at least 12 to 24 hours being recommended). In recent years and thanks to the advent of CZT semiconductor cameras dedicated to cardiology - to perform a dynamic tomographic acquisition - a study of the coronal reserve is feasible by perfusion tomoscintigraphy in current practice. This study of the coronary reserve mainly consists of a computer post-processing of the myocardial perfusion scintigraphy data and does not therefore require any additional irradiation (the only difference with respect to the old protocols is the start of the images at the time of publication. injection of the radiotracer). However, the diagnostic benefit gained from the coronary reserve study compared to conventional stress / rest perfusion scintigraphy has not been clearly studied, particularly in the multi-truncal patients.
Cardiovascular rehabilitation (CVR) has major beneficial effects by improving physical capacity, accelerating return to activities and reinsertion and reducing mortality. It associates reconditioning to effort and therapeutic education for the optimal control of " risk factors ". It corresponds to a global approach to patients, thus counterbalancing the tendency to hyperspecialise in medicine. However, because of the lack of specialised centres, only a small proportion of patients (≈30%) are able to benefit. Numerical tools used in e-health, the deployment of the Internet and certain " connected " devices may provide alternatives outside hospital, by enabling the follow-up of patients and their physiological parameters (heart rate, blood pressure, weigh, physical activity…), and the adaptation - using an interactive web platform - of the physical activity programme, nutrition, compliance with medication and weaning from smoking. This project proposes to evaluate the effects of a so-called " connected " CVR programme, and to show its non-inferiority compared with a conventional CVR.
This study is designed to directly compare Standard Care and CT fractional flow reserve (CTFFR) for diagnosis of chest pain patients with definite coronary artery disease (CAD) on heart computed tomography (CT) scans.
This study evaluates a smartphone-based cardiac rehabilitation program in adults with coronary artery disease. Half of patients will participate in a smartphone-based cardiac rehabilitation program while the other half will receive standard-of-care.
Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).
This study aimed to compare the efficacy and safety of P2Y12 inhibitor monotherapy versus extended dual antiplatelet therapy (DAPT) following 12-month of DAPT in patients undergoing percutaneous coronary intervention (PCI) with bioresorbable scaffold (BRS)
SilverCloud provides internet-delivered interventions for depression and anxiety in NHS Mental Health Services. The interventions have proved successful in the management of depression and anxiety for clients presenting to mental health services, with recovery rates exceeding the national standard. Recently SilverCloud has embarked on tailoring the interventions for patients with long-term conditions including COPD, pain and diabetes. The purpose of the customisation is to make the interventions more meaningful and relevant to patients with LTCs, but all the while having the same goal of addressing depression and anxiety disorders. In doing so it would be expected that individuals might be in a better position to effectively self-manage their LTC. The current study, therefore, seeks to assess the possible effectiveness of implementing customised internet-delivered interventions for depression and anxiety for people with long-term conditions presenting to NHS mental health services.
LEADERS-FREE trial demonstrated the safety and efficacy of polymer-free drug-coated stent (Biofreedom, Biosensors International Technologies, Singapore) in patients with high bleeding risk. But, there are limited clinical evidences for extending these findings to generalized patients who are eligible to PCI. Therefore, the purpose of this registry is to evaluate the safety and efficacy of Biofreedom stent in patients with coronary artery disease.
The study is a single-center, interventional, pilot study to evaluate the improvement of microvascular function by positron emission tomography (PET) after twelve-week treatment of oral nicorandil in female non-obstructive CAD Participants.
The goal of this study is to correlate both plaque and % lipid core content assessed by NIRS-IVUS (Imaging technique) to plaque burden and % lipid core content in coronary computerized tomographic angiography (CCTA) completed at 1 week in non-culprit coronary arteries.
