Filter by:The study aims to evaluate clinical characteristics and prognostic of a contemporary population of patients with UA defined using T hs-cTn measurements The study includes all patients admitted in 2 French university centers with the confirmed diagnostic of UA defined with clinical ischemic symptoms and T hs-cTn concentrations < 99 percentile (undetectable: <5ng/l or non-elevated: <14ng/l), or ≥ 99 percentile but mildly elevated (14-50ng/l) .The primary end-point included major events at 1-year follow-up (total mortality, new ACS, hospitalization for cardiac causes).
Calcification of the coronary arteries is a direct sign of atherosclerotic disease of the coronary arteries and has been shown to be a strong predictor of the risk of cardiovascular diseases, including myocardial infarction and/or cardiac death, especially in patients with Diabetes Mellitus type 2. Therefore, there is great interest in pharmacotherapies that improve the rates of cardiovascular complications, and modify the outcomes of this group of patients. Large randomized controlled trials with SGLT2 inhibitors in patients with DM2 have shown a clear reduction in cardiovascular events among individuals with atherosclerotic disease. Atherosclerosis imaging allows measurable assessments of disease progression and activity, revealing early signs of potential drug effects. Noninvasive methods are preferred for serial imaging in drug trials due to the potential risks associated with invasive procedures. The coronary artery calcium quantification using the Agatston score is the most widely used method
To determine change of QTc interval during intravenous argatroban infusion in patients undergoing percutaneous coronary intervention (PCI)
The study includes two parts: Part 1: - 100 examinations of patient referred for echo evaluation, containing clips that were acquired from the 4CH apical view were collected retrospectively. Each study includes 10 clips that represent typical user scanning errors - Offline evaluation of the system (by batch processing) shall be performed by comparing the system output to preliminary quality tagging by experienced sonographers Part 2: - Live scans of apical 4CH clips of patients with indication for POCUS examination will be performed by POC physicians - LVivo IQS shall be used (on Lumify) during the scan for patients that meet inclusion criteria until 50 exams will be collected. 3 sec of each scan shall be saved, and Image quality score (IQS) shall be documented - Saved scans shall be reviewed by an expert physician to determine whether they are clinically interpretable
The Global Cardiovascular Risk Consortium (GCVRC) comprises harmonized data from nearly 1.7 Mio individuals of 126 cohorts across 43 countries and aims to elucidate the distribution of five major cardiovascular risk factors (body mass index, systolic blood pressure, non-high-density lipoprotein cholesterol, current smoking, and diabetes) and their impact on cardiovascular disease (CVD) by geographical region and sex.
Radial approach is widely established in cardiac diagnostic and therapeutic treatments. It has been shown to decrease bleeding, vascular problems, and mortality rates when compared to the femoral approach. It also offers better comfort to patients through early mobility and lowers hospital expenses. Previously, there were no specific devices for radial artery hemostasis. Many different types of dressings were used in various hospitals with no standardization. This raises the question of whether specific devices surpass dressings in terms of patient comfort, time required to maintain hemostasis, and vascular complications. The primary goal of this study was to examine the effectiveness of compression dressings and hemostatic wristbands on patients undergoing cardiac procedures via radial approach in terms of patient comfort, time required to maintain hemostasis, and vascular problems. The hemostatic wristband TR BandR (Terumo Corporation, Tokyo, Japan) was utilized in one group, while compressive elastic dressing, standardized as 13 threads gauze overlapped, opened, longitudinally pleated once and wrapped, making a 5-cm long cylinder, 1-cm in height, was used in the other.
With the Emergency Medical Services (EMS), no prehospital risk stratification and triage is performed for patients suspected of having an Non-ST-segment elevation Acute Coronary Syndrome (NSTE-ACS). While the latest ESC Guidelines recommend an early invasive strategy within 24 hours for all high risk NSTE-ACS patients and same-day transfer to a PCI (Percutaneous Coronary Intervention) center. With the potential emerging logistical problem surrounding this, prehospital risk stratification and triage can have great benefits in this population as well, especially in patients with a high risk of having an NSTE-ACS. The recently validated PreHEART score makes it possible to stratify patients in a low-risk and high-risk group for having a NSTE-ACS and gives the EMS the opportunity to make triage decisions in the prehospital setting. Patients with a high risk for having an NSTE-ACS are transferred directly to an PCI-center for further diagnostic work-up. Patients with a low risk for having NSTE-ACS and transferred to the ED of the nearest hospital without PCI facilities (non-PCI center) for further diagnostic work-up, resulting in an optimization of the regional care utilization. This is the first study to focus on patients who are at a high risk of having an NSTE-ACS and to assess if whether prehospital triage using the PreHEART score is able to significantly reduce time to final invasive diagnostics and revascularization in patients in need of coronary revascularization.
Cardiac rehabilitation after an acute coronary syndrome is recognised in the latest guidelines and recommendations published by the major scientific societies as a class I indication. Despite this evidence, the number of patients entering such programmes in Europe is still around 30%. The present study aims to validate a new comprehensive Telerehabilitation System to provide support for cardiac rehabilitation, to optimize it and to test its usefulness in terms of improving adherence to physical exercise and cardiovascular risk parameters.
The global burden and threat of non-communicable diseases (NCDs) have become a major health challenge that undermines social and economic development throughout the world. Cardiovascular disease including acute coronary syndromes (ACS) currently accounts for 17.9 million deaths a year. Low and middle-income countries such as those in sub-Saharan Africa (SSA) have undergone a rapid epidemiological transition over the last few decades and now have a burden of disease increasingly dominated by NCDs. The global burden of disease report for 2017 revealed a 71.4% increase in cardiovascular disease in SSA, predicting a large increase in mortality. Unfortunately, reliable population-level data regarding the incidence, prevalence and demographics of ACS in SSA are limited. The investigators propose to set up and conduct a multi-centre, prospective, observational registry to describe the demographics, clinical characteristics, presentation, management and outcomes of patients admitted with ACS in Cape Town and the Garden Route Health District, Western Cape Province, South Africa. The registry is designed to shed insight on the current burden and impact of atherosclerotic cardiovascular disease in the Western Cape.
Prospective (analysis of retrospective data), multi-center, observational, single-arm study. This structure was selected as the "worst case" due to the fact that it represents real life usage of invasive FFR measurement is performed mostly in "gray zone" cases, which are that their severity cannot be determined intuitively and based on the physician eyeball. By using real-world historical data of invasive FFR, the analysis of the obtained data can ensure that the study results are expected to include invasive FFR results that are in the grey zone, when invasive FFR is used in real life and represent the real expected use of the product. Furthermore, the analysis of the data obtained in the studies with these similar devices measuring FFR obtained from angiograms was actually performed in a retrospective manner. That is, although the angiographic images and pressure wire recordings were obtained in real-time, due to the need to mark the vessel in real-time and obtain specific projections during the procedure without which the FFR cannot be calculated, the primary endpoint (sensitivity and specificity) and accuracy were determined in all studies by a post-hoc review by a similar independent QCA core laboratory. The invasive FFR data, as well as the software generated FFR data were reviewed post-hoc by a core laboratory or even at the company.
