The study aims to evaluate the safety and effectiveness comparisons between warfarin, dabigatran, and rivaroxaban in routine clinical practice among Japanese non-valvular atrial fibrillation (NVAF) patients with concomitant coronary artery disease (CAD).
Coronary heart disease (CHD), the major group of cardiovascular disorders, is the leading cause of cardiac-associated mortality, causing >9 million death in 2016. American Heart Association (AHA) and the American College of Cardiology Foundation (ACCF) recognized that lifestyle modification including physical activity is the class one-level recommendation for secondary prevention and risk reduction therapy for patients with CHD. The assessment of physical activity and confidence in performing exercise for patients with CHD will help healthcare professionals to develop and implement the appropriate intervention to enhance patients' confidence in performing exercise and physical activity to promote and maintain their health. With the increasing morbidity and mortality from CHD, especially in low and middle-income countries, secondary prevention including exercise-based cardiac rehabilitation (CR) plays an important role to improve the prognosis of CHD patients. High prevalence of physical inactivity, unhealthy dietary practices, poor control of blood glucose, blood pressure (BP), blood lipid, and body weight (BW) was found among CHD patients in the world as well as in Sri Lanka. Therefore, it is important to design and implement an appropriate intervention to improve the physical activity level, exercise self-efficacy, and cardiovascular risk factors in CHD patients in Sri Lanka. This study aims to develop and examine a culturally specific motivated, action-based intervention for improving physical activity level, exercise self-efficacy, and cardiovascular risk factors of CHD patients in Sri Lanka. The participants will be patients who admitted to the coronary care unit (CCU) and medical wards of the Teaching Hospital Batticaloa, Sri Lanka with CHD for the first time confirmed by electrocardiogram with aged 18 years or above, able to reads and speak Tamil, able to attend clinic follow-up, obtain a medical clearance from a cardiologist to perform the exercise and, able to understand and give informed consent. The medical records of the CHD patients will be reviewed to screen for their eligibility. In addition, the cardiologist of the participants will be consulted for their suitability to perform the exercise of the intervention. The purpose of the study, the data collection procedures, the potential risk and benefits, the maintenance of confidentiality, and the voluntary basis of participation will be clearly explained to the participants, and informed written consent will be obtained before data collection. Ethical approval was obtained from The Joint Chinese University of Hong Kong - New Territories East Cluster Clinical Research Ethics Committee and Ethics Review Committee, Faculty of Health Care-sciences, Eastern University, Sri Lanka. The Statistical Package for Social Science version 22.0 software (SPSS 22.0) will be used to analyze the data and the p-value less than 0.5 will be considered as significant. This study will provide evidence on the effectiveness of a motivated, action-based intervention on the physical activity level, cardiovascular risk factors, and exercise self-efficacy of CHD patients in Sri Lanka. Findings from this study could be useful to promote healthy lifestyle behaviors in CHD patients in a low-resource setting. Furthermore, this study will provide information on which level this intervention could be applied and possible constraints that hinder the outcomes of the results.
This study aims to examine the impact of providing a digital education material to participants of home based cardiac rehabilitation in improving clinical and behavioural outcomes
The objective of this study is to evaluate the effectiveness and safety of Synergy XD stent and Synergy Megatron™ Stent in the "real world" daily practice as compared with the other drug-eluting stents.
Improvement of patients' care and outcome is largely based on development and validation of drugs and technologies, especially in rapidly evolving fields as Interventional Cardiology. In fact, even though the optimal efficiency of a cathlab can be influenced by Interventional Cardiologist's mental workload, stress' accumulation and performance, little if any attention is paid to the monitoring and optimization of his/her mental status. Electroencephalogram (EEG)-based neural-interfaces are able to estimate workload, fatigue and the degree of sleepiness through spectral analysis techniques. In particular, the amplitude of alpha waves is a widely validated indicator of mental engagement's level. Developing a low cost and highly feasible device to monitor and analyze operator's mental engagement level and performance could be extremely appealing, especially considering both the lack of data in literature for interventional disciplines and the recent technology developments.
This study is aimed to evaluate the effect of the optimal heart team implementation protocol on the stability of decision-making for patients with complex coronary artery disease.
Selection of the appropriate administered activity for each patient's body habitus is very important to obtain diagnostic image quality. Current SPECT imaging guidelines suggest "…an effort to tailor the administered activity to the patient's habitus and imaging equipment should be made… [however] strong evidence supporting one particular weight-based dosing scheme does not exist." An increase in body weight leads to higher fractions of attenuated and scattered photons, resulting in lower quality PET images for a given injected activity. Weight-based tracer dosing is commonly recommended as a solution in whole-body PET imaging with F-18-FDG. In contrast, Rb-82 PET imaging has traditionally been performed using a single dose (e.g. 40 mCi) administered for all patients but this is known to result in lower count-density and image quality in larger patients. This effect can be mitigated to some degree by administration of Rb-82 activity as a proportion of body weight while maintaining accuracy for the detection of disease. The objective of this project is to determine whether Rb-82 activity administered as a squared function of patient weight (quadratic dosing) can standardize PET myocardial perfusion image quality over a wide range of body weights. Sequential patients referred for dipyridamole stress Rb-82 PET perfusion imaging at the University of Ottawa Heart Institute. Patients will be divided into 4 weight groups to determine if there are significance differences in image quality or accuracy of injected Rb-82 activity between patients. Twelve (12) patients will be recruited in each of the 4 weight groups (3 in each 10 kg interval) to uniformly sample the full range of patient weights from 30 to 190 kg. Based on the previous oncology PET literature image quality is not expected to change as a function of weight, i.e. SNR and CNR will be proportional to weight0 (no weight-dependence) with quadratic dosing of Rb-82. Two operators will perform the PET image analysis as described above.
Patients with type 2 diabetes mellitus (DM) have higher risk of major cardiovascular events (MACE) and renal disfunction. The Sodium-glucose cotransporter-2 inhibitors (iSGLT2) reduces hyperglycemia in patients with type 2 DM and have multiple metabolic effects, lowering primary composite cardiovascular outcomes and progression to renal failure. 25% of patients with Stable Ischemic Heart Disease (SIHD) undergoing PCI are diabetics being one of the most prevalent and important risk factors for the development of contrast induced nephropathy (CIN). The occurence of CIN is associated with higher rates of death, loss of renal function, necessity of dialysis and increase of health care costs. In this pilot study we sought to evaluate if the iSGLT2 would prevent periprocedural complications - such as periprocedural CIN and MI - in type 2 DM patients undergoing PCI through the assessment of renal and myocardial biomarkers
In this study, quantitative characterization of plaque using coronary computed tomographic angiography (CTA) will be used to determine if women who were treated with intensive medical therapy have a greater reduction in the amount and type of cholesterol plaque compared to women receiving usual care and if this results in beneficial changes in clinical symptoms. The study will provide an understanding of how intensive medical therapy works in providing clinical benefit in women with nonobstructive plaque.
