The goal of this registry is to collect data on patients referred for clinically indicated coronary vasomotor function test (CFT) and answer different questions on prevalence, safety and outcomes. The registry is observational. Patients receive yearly online questionnaires on their anginal complaints for 5 years after their CFT.
The goal of this clinical trial is to learn about the effect of a booster program aiming to lower daily sitting time (SIT LESS Booster program) compared to usual care in patient with coronary heart problems. The main question it aims to answer is: What is the effect of the SIT LESS Booster on sedentary time and physical activity levels in patient with coronary artery disease who participated in cardiac rehabilitation. Participants will be randomized into 2 groups: 1. Control group who receives usual care; 2. SIT LESS Booster group who receives usual care + a remote 3-week SIT LESS Booster program. Objectively measured changes in daily sitting time from pre- to post SIT LESS Booster will be compared between groups to see if participants in the SIT LESS Booster group are able to reduce daily sedentary time more compared to participants in the control group.
A long-term evaluation of the impact of intensive diet and lifestyle intervention on coronary plaque dynamics in patients with coronary atherosclerosis diagnosed in computed tomography angiography (CCTA). 92 patients who completed the Dietary Intervention to Stop COronary Atherosclerosis in Computed Tomography study (DISCO-CT, NCT02571803) will be followed-up.
The goal of this observational study is to develop an automatic whole-process AI model to detect, quantify, and characterize plaques using coronary CT angiography in coronary artery disease patients. The main questions it aims to answer are: 1. Whether the AI model enables to detect and quantify coronary plaques compared with intravascular ultrasound or expert readers; 2. Whether the AI model enables to identify vulnerable plaques using intravascular ultrasound or optical coherence tomography as the reference standard. 3. Whether the AI model enables to predict future adverse cardiac events in a large cohort of 10,000 patients with non-obstructive CAD.
This is a long-term follow-up of a completed clinical trial which compared percutaneous coronary intervention (PCI) using sirolimus-eluting stents and coronary artery bypass grafting (CABG) in patients with unprotected left main coronary artery disease. The purpose of the study is to obtain retrospective long-term data on clinical outcome of the study population.
This study aims to evaluate the effects of cardiotoxic cancer therapies on myocardial blood flow (MBF) and perfusion in a prospective sample of VA patients.
This pragmatic clinical trial embedded in an accountable care organization will determine the comparative effectiveness of two approaches for assigning care coordinators to older adults at risk for cardiovascular outcomes. The hypothesis is that assigning care coordinators to older adults based on perceived need will be more effective at preventing emergency department visits and hospitalizations compared to usual care.
To describe the prevalence and clinical features of patients with severe aortic stenosis undergoing TAVI and concomitant clinically indicated, complex and/or high-risk PCI
The use of pre-test probability (PTP) and coronary artery calcium (CAC) scores is guideline-recommended in the evaluation of coronary artery disease (CAD) and stable chest pain. The utility of these scores is population dependent. Previous studies have predominantly been limited to Western populations, despite Asia forming 60% of the global population. However, Asian populations have differing coronary artery phenotypes and may therefore have different PTPs with varying implications for risk stratification. Known difference in CAC implications support a global approach. Hence, this study aims to evaluate a contemporary PTP in diverse real-world Asian, Western and other cohorts and to evaluate the incremental value of CAC in predicting CAD and events. Primarily, the study will compare population specific PTPs and CAC for prediction of coronary computed tomography angiography (CTA) CAD. This could be compared with existing guideline-recommended PTPs alone or with consideration of risk factors or CAC. The study will also evaluate the accuracy of the prediction of major adverse cardiovascular events (MACE) using PTP models, risk factors and/or CAC. Lastly, the study will investigate the accuracy of zero CAC and other minimal risk tools to de-risk cardiovascular disease (CVD) in various populations. The study will investigate multiple international cohorts of patients referred for noninvasive testing using coronary CTA or other non-invasive imaging modalities. Locally-calibrated PTP models in consideration of risk factors or CAC will be separately tailored to each different cohort, and will be evaluated.
The goal of this randomized controlled clinical trial in asymptomatic individuals with risk factors for cardiovascular disease is to investigate whether a preventive treatment strategy guided by computed tomography coronary angiography (CTCA) provides a patient-centered approach, which ensures optimal protection against serious cardiovascular disease. The main question it aims to answer is: Does preventive treatment guided by CTCA reduce the risk of heart attacks or cardiovascular death as compared to using conventional cardiovascular risk scores. Participants will be randomized to preventive medical therapy and/or invasive intervention guided by either CTCA (intervention group) or Systematic COronary Risk Evaluation (SCORE) 2 model for cardiovascular risk prediction (control group).
