Filter by:The purpose of this study is to determine whether administration of a pecto-intercostal fascial plane block (PIFB) with bupivacaine is a more effective therapy for postoperative analgesia after cardiac surgery as compared to patients who receive a sham block of normal saline.
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.
The SYNTAX-score has been proposed as a tool for risk stratification and guiding revascularization therapy in patients with complex coronary artery disease. There are limited data on the prognostic value of the SYNTAX-score among elderly patients. Aim of this study was to investigate whether age modifies the impact of the SYNTAX-score on all-cause mortality at 2 years after percutaneous coronary intervention (PCI).
The primary objective of the Sleep and Stent II is to determine the prevalence of REM-OSA in DM versus non-DM patients undergoing clinically indicated PCI. The secondary objectives are to investigate the association between REM-AHI and (1) cardiac arrhythmia based on ambulatory ECG monitoring, (2) excessive daytime sleepiness, and (3) glycemic control in patients with DM. In addition, we will determine the prevalence of REM-OSA based on alternative definitions, including (a) overall AHI at least 5 with AHI REM/AHI NREM ratio at least 2; (b) overall AHI at least 5 with AHI REM/AHI NREM ratio at least 2 and with AHI NREM < 15; (c) overall AHI at least 5, AHI REM/AHI NREM ratio at least 2 and with AHI NREM < 8.
Background: Exercise-based cardiac rehabilitation (CR) is the gold-standard in tertiary prevention of coronary artery disease (CAD), yet average CR attendance is only 67%. Patient education is commonly delivered during CR to impart information about CAD and its risk factors. An underlying assumption is that knowledge will enhance patients' attitudes toward CR, promote better program adherence, and improve clinically relevant cardiovascular outcomes. However, more formative work is needed to characterize the impact of patient education delivered in a CR setting on purported mechanisms-of-action in order to optimize efficacy. Few cardiac patient education interventions have been empirically validated, and it is unclear whether knowledge gains from education translate to improved CR attitudes and program adherence. Objective: This study aims to 1) examine the association between cardiac patient education and changes in knowledge about CAD, and; 2) explore whether changes in knowledge correspond to (a) improved attitudes about CR (perceived necessity, concerns about exercise, practical barriers, perceived personal suitability), and (b) increased CR adherence. Hypothesis: It is expected that 1) knowledge will increase from pre- to post-patient education, and 2) knowledge gains will be associated with improved CR attitudes and better CR adherence. Methods: 100 adults with CAD referred to outpatient CR will be recruited prior to attending four, mandatory 2.5-hour-long group-based education classes. Patients will subsequently attend supervised CR exercise sessions twice-weekly for 12 weeks. Validated questionnaires assessing knowledge about CAD and attitudes toward CR (i.e., perceived necessity, exercise concerns, barriers, perceived suitability) will be completed pre- and post-cardiac education classes, and 12-weeks post-CR. Adherence (# of CR exercise sessions attended) will be obtained by chart review. Implications: This study will help identify whether patient education delivered in a CR setting impacts hypothesized treatment targets and inform future efforts to optimize behavioral interventions for increasing CR utilization
The investigators present an interesting co-incidence of Gated wall abnormality in the inferolateral wall in normal sestamibi myocardial perfusion images with J wave in the inferior derivations of the ECG in a patient. The subsequent coronary angiography demonstrated 80% mid right coronary artery (RCA) stenosis, which was intervened with a drug-eluting stent. The investigators conclude that even though the myocardial perfusion is normal, the association of gated wall abnormality with J wave presentation within the same location should be further evaluated.
How safe and effective are CD34+ cell intracoronary injections for treating coronary endothelial dysfunction (CED)?
Prospective, multicenter, single arm registry to monitor post-market clinical outcomes of patients treated with Inspiron Sirolimus-Eluting Stent with Biodegradable Polymer.
The purpose of this trial is to investigate the relationship between DNA methylation and hydroxymethylation and the expression of DNMTs, TET family gene and the degree of coronary heart disease.
