Introduction: Regular exercise training improves prognosis in patients with coronary artery disease (CAD). This study investigates whether the beneficial effects of exercise can be partly explained by favourable changes in haemostasis and inflammation. Methods: 150 CAD patients are randomised to a supervised long-term exercise program (3 months) or usual care. Blood samples are obtained at baseline, 1.5 months, and 3 months after randomisation. Results: The investigators will evaluate platelet turnover and aggregation, coagulation, fibrinolysis, and inflammatory markers before and after short- and long-term exercise, and the two randomised groups will be compared. Perspectives: The present study will increase our knowledge of the beneficial mechanisms underlying the effect of exercise in CAD patients, potentially paving the way for improved exercise recommendations.
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).
Drug-coated balloon (DCB) is an alternative choice for patients with coronary artery disease (CAD). This study is to investigate the efficacy and safety of DCB treatment in patients with CAD.
Drug-coated balloon (DCB) is an alternative choice for denovo lesions in coronary artery disease patients with high bleeding risk. Intravascular ultrasound (IVUS) can provide more details of coronary anatomy and stent implantation, overcoming a number of limitations of coronary angiography. However, the benefit of IVUS-guided DCB treatment has not been investigated. This study is designed to compare IVUS-guided and Angiography-guided DCB treatment for coronary denovo lesions in patients with high bleeding risk.
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).
Severely calcified coronary stenoses are difficult to treat with percutaneous coronary intervention (PCI) using current techniques and there is little specific evidence on how to best treat these cases. It is hypothesized that balloon lithoplasty is superior to conventional balloons for lesion preparation of severely calcified coronary lesions before stent implantation in terms of procedural failure and 1-year target vessel failure.
Older patients with co-morbidity are increasingly represented in interventional cardiology practice. They have been historically excluded from studies regarding the optimal management of NSTEACS. Though there are associated risks with invasive treatment, such patients likely derive the greatest absolute benefit from PCI. Small, though highly selective, studies suggest a routine invasive strategy may reduce the risk of recurrent myocardial infarction. The study aims to include, as far as possible, an 'all-comers' population of patients aged 80 and above to define the optimum amount of revascularization required to achieve good outcomes and satisfactory symptom relief for this challenging cohort of patients.
