Filter by:The objectives of this pilot RCT are to examine if the Talk Test is an effective and safe tool as compared with CPET for exercise prescription in patients who have undergone CABG or PCI and enrolled in a home-based CR program with virtual exercise training monitoring.
Coronary heart disease (CHD) is a major cause of morbidity, disability, mortality, and health expenditures worldwide. A wealth of studies has demonstrated that people of South Asian ancestry have a higher risk of CHD and particularly premature CHD than most other racial/ethnic groups, and recent research suggests that this risk is higher in Pakistanis than in Indians-the two largest SA groups. Pakistan is the 5th most populous country in the world, and despite these concerning trends, so far there has been a scarcity of large studies evaluating the prevalence of cardiovascular risk factors and subclinical coronary atherosclerosis in young-to-middle-aged Pakistanis. Also, there is currently no cardiovascular risk score specifically tailored to younger Pakistani men and women. The PAKistan Study of prEmature coronary atHerosclerosis in young AdulTs (PAK-SEHAT) aims at addressing these important gaps. PAK-SEHAT is an ongoing prospective cohort study that will enroll 2,000 asymptomatic Pakistani men aged 35 to 60 years and women aged 35 to 65 years from the general population, free of clinically overt cardiovascular disease. Participants will undergo a comprehensive baseline exam including coronary computed tomography angiography, and will be followed for incident events and repeat testing for 5 years. PAK-SEHAT will allow determining the prevalence, severity, determinants, and prognostic significance of early atherosclerosis in apparently healthy young-to-middle-aged Pakistanis. This knowledge can help inform primordial and primary prevention strategies, enhanced cardiovascular risk stratification, and potential plaque-screening approaches in Pakistan, all of which can ultimately help reduce the burden of CHD in the country. In this report investigators describe the rationale, objectives, methods, and discuss the potential implications of the PAK-SEHAT study.
Multidisciplinary team-approach in order to offer personalized treatments represents the emerging mainstream in cardiovascular medicine. "Hybrid operative rooms" allow to offer selected heart-disease patients truly "tailored" operations. This study wants to evaluate the effectiveness and safety of Hybrid Procedures in cardiac patients in three subgroups of patients: - Hybrid coronary revascularization strategy (coronary by-pass + PCI); - Hybrid valve and coronary disease correction (combination of surgical valve replacement and PCI); - Hybrid coronary and carotid artery disease treatment (combination of coronary by-pass and carotid stenting). The investigators hypothesize that morbidity might be reduced by 50% in hybrid procedures group as compared with predicted Society of Thoracic Surgery (STS) score.
This study sought to assess the diagnostic and prognostic values of metabolomics in coronary artery disease(CAD).
This a Phase 3, prospective, open-label, multicenter study of [15-O]-H2O injection for PET imaging of subjects with suspected CAD. Approximately 182 evaluable participants with suspected CAD referred for testing will be included in the study at approximately 10 study sites in the United States and Europe. Approximately 215 participants will be enrolled to account for an estimated 15% drop-out rate. Screening assessments will occur prior to enrollment to confirm eligibility. All participants will receive two doses of [15-O]-H2O as part of a single PET imaging session (one dose at rest and one during pharmacological stress with adenosine). A safety follow-up phone call will occur 24 ± 8 hrs after completion of the [15-O]-H2O scan.
To evaluate the long-term clinical outcomes and prognostic factors in patients with coronary artery disease (CAD) undergoing invasive coronary angiography (ICA), intravascular imaging, or invasive physiologic assessment.
This study is being done to observe the effects of treatment from a device called the Bioboosti which utilizes pulsed electromagnetic waves on its ability to improve blood flow to the heart tissue in individuals with coronary artery disease (CAD).
Today, MRI is the gold standard for the precise assessment of left ventricular volume and function, but presents the drawback of having a long acquisition time and of generating motion artifacts, in particular respiratory artifacts, requiring repeated sequences in apnea to cover the whole cardiac volume. These apneas are difficult to achieve in patients with ischemic heart disease and may lead to degradation of the images, an increase in the duration of the examination by repeated acquisitions and therefore to diagnostic inaccuracies. Artificial intelligence, already used in practice in cardiac MRI for automatic segmentation of the heart chambers, improves radiological interpretation with rapid and precise measurements. Deep-learning, which is part of artificial intelligence, would allow the reconstruction of cine-MRI sequences in free breathing, in order to overcome the artifacts from respiratory motions, and the improvement of diagnostic performance while improving examination conditions for patients. Patients coming for a cardiac MRI for the assessment of ischemic heart disease will be eligible to the protocol. If the patient agrees to participate, a free-breathing cardiac cine-MRI sequence with Deep Learning based image reconstruction will be added to the usual protocol. No follow-up will be required in this study.
In addition, studies have found that indobufen can inhibit coagulation function in rats. Compared with aspirin, the duration of antiplatelet efficacy of indobufen was shorter, and the platelet function recovered completely 24 hours after drug withdrawal. However, there are few studies on the antiplatelet efficacy of indobufen. The investigators' previous study found that the inhibitory effect of indobufen 100 mg Bid on COX system in atherosclerosis or healthy volunteers was equivalent to that of aspirin 100 mg QD, but the inhibitory effect on platelet COX-1 channel was significantly weaker than that of aspirin 100 mg QD. In view of this, this study intends to investigate the antiplatelet effect of indobufen 200 mg Bid in patients with coronary atherosclerosis by comparing it with conventional-dose aspirin 100 mg QD.
Today, 50 % of cardiac patients do not participate in cardiac rehabilitation due difficulties in navigating and accessing rehabilitation activities. HeRTA is a partnership project involving Center for Clinical Research and Prevention (CCRP), Hvidovre Hospital, Rehabilitation Center Albertslund and Copenhagen (municipalities), the Danish Heart Association, and local sports associations. A patient advisory board participate throughout the project to ensure a continued focus on patient interests. The overall aim of HeRTA is to develop and test the feasibility of a new, sustainable model for rehabilitation supporting patients to take part in rehabilitation and promoting life-long activity for all patients with heart disease. To ensure equal access to rehabilitation some activities are open to all patients, while others are tailored specifically to patients with vulnerability. The project unfolds in three phases: Development (1. January 1. 2020 - 14. November 2021): Partners and patients co-create content and procedures; Feasibility (15. November 2021 - 31. July 2023): The feasibility of the model is tested, and promising components are identified; Long-term follow-up and implementation (1. August 2023 - 31. December 2025): Long term effects are investigated and promising components are tested in new settings. During the feasibility phase the investigators will examine whether the intervention activities are feasible, acceptable, and may have positive effects for patients with heart disease. The investigators use qualitative data on implementation and acceptability of intervention among partners and patients. An randomisered controlled trial (RCT) component will assess effects on patient participation rates, health, physical activity level, and life quality. Data is collected from practitioners and patients through focus groups, observations, field notes, questionnaires, and interviews. Results will point to: - innovative ways to organize integrated rehabilitation pathways. - approaches to ensuring rehabilitation targeted at patient needs.
