Filter by:Coronary physiologic assessments by the pressure-derived fractional flow reserve (FFR) have become standard methods for identifying hemodynamic deprivation in coronary arterial stenosis for evidence-based percutaneous coronary intervention (PCI). Invasive physiologic indices-guidance enables on-site real time assessment for functional significance of epicardial coronary stenosis and the use of those indices has shown to be effective to guide treatment decision. Several studies further support the role of post-PCI FFR measurement as a functional marker of residual disease after PCI and prognostic indicator of patients. Although optimal cut-off values of post-PCI FFR varied across studies, an inverse relationship between post-PCI FFR and the risk of future clinical events have been reported consistently. Recently, non-hyperemic pressure ratios (NHPRs) have been introduced in clinical practice. Although there are several different NHPRs, previous studies consistently indicated that those NHPRs shares similar diagnostic performance and prognostic implications. Nevertheless, few reports were available for clinical relevance of NHPRs in evaluation of post-PCI status. In this context, we will evaluate the physiologic characteristics and prognostic implication of post-PCI NHPRs and compare with those of post-PCI FFR in patients who underwent angiographically successful PCI with 2nd generation drug-eluting stent implantation (DES).
The overall objectives of the Optima project is to: (1) Compare the effect of standardized group based cognitive therapy and cardiac rehabilitation versus usual cardiac rehabilitation in patients with sign of psychological distress measured by a questionnaire (HADS score), (2) To investigate spontaneous variation in psychological distress with HADS over time in order to optimize time of measuring HADS. (3) To investigate if the intervention can be implemented to other cardiac rehabilitation sites with the same effect as on BFH (that it is not person dependent).
Main objective: To assess the efficacy of a phase III cardiac rehabilitation program (CRP), based on counseling in the maintenance of physical exercise (time of physical exercise per week) for patients with myocardial ischemia (MI), once the supervised physical exercise program of phase II of CRP is completed. Secondary objectives: To assess the efficacy of a phase III program of CRP based on counseling in the maintenance of physical exercise for the patient with MI in: 1) the energy expenditure per week, 2) body mass index and abdominal perimeter, 3) control of cardiovascular risk factors (smoking, high blood pressure, dyslipidemia and diabetes mellitus), 4) quality of life related to health, 5) assess the adherence to cardiac pharmacological treatment. Method: Randomized clinical trial in conglomerates, open and controlled. The intervention group will carry out phase III of CRP based on counseling in the maintenance of physical exercise. The control group will receive the usual care. The main outcome will be the physical exercise time per week after finish the supervised physical exercise program of phase II of CRP and at 6 and 12 month later according to the 7-day Physical Activity Recall.
This is a prospective, multicenter, randomized controlled clinical trial, which plans to enroll 260 subjects.
The purpose is to observe and evaluate the safety and efficacy of Bingo drug-coated balloon in the real world.
The main objective of the study is to demonstrate that the inclusion of eggs to a plant-based diet will not increase the risk for heart disease but will increase the concentration of lutein and zeaxanthin, two important antioxidants and will also increase choline, an important component of membrane phospholipids.
Coronary artery disease (CAD) is the leading cause of death in Trinidad and Tobago. Early detection and management can help improve morbidity and mortality. Retinal artery microvascular disease has been shown to directly correlate with coronary artery disease. Retinal artery calibre screening via the Optic Coherence Tomography (OCT) will provide a non-invasive method of diagnosing CAD.
This observational prospective clinical study is to develop software tools to fuse coronary anatomy data obtained from CT coronary angiography with dynamic PET data to noninvasively measure absolute myocardial blood flow, flow reserve and relative flow reserve across specific coronary lesions. Results will be compared to those obtained invasively in the catheterization laboratory.
The purposes of this study are 1) to explore the variability of decisions between different heart teams in complex coronary artery disease; 2) to evaluate the reasons of the discrepancy in decision making.
The study is a randomized, single-dose, open-label, combined 2x2 dose and 3x3 dose crossover design in fixed sequence. In this study, the relative bioavailability of different formulations of AZD5718 will be assessed in healthy volunteers in order to compare the exposure of Formulations A to D to the AZD5718 film-coated tablet formulation. The overall treatment period will start with a 2-period, 2-dose treatment crossover, followed by a 3-period, 3-dose treatment crossover.
