Incidence, Clinical Characteristics and Outcomes of Unstable Angina in the contempoRary Area.

ICAR
Start date: November 27, 2022
Phase:
Study type: Observational

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).

NCT ID: NCT05998525 Completed - Clinical trials for Diabetes Mellitus, Type 2

Dapagliflozin Effects on Coronary Calcium and Epicardial Fat Assessed by Cardiotomography

Start date: June 21, 2021
Phase: Phase 3
Study type: Interventional

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

NCT ID: NCT05563701 Completed - Heart Diseases Clinical Trials

Evaluation of the LVivo Image Quality Scoring (IQS)

Start date: September 5, 2022

Study type: Observational

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

NCT ID: NCT05243485 Completed - Unstable Angina Clinical Trials

Prehospital Triage of Patients With Suspected Non-ST-segment Elevation Acute Coronary Syndrome: the TRIAGE-ACS Study

Start date: April 1, 2021
Phase:
Study type: Observational

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.

NCT ID: NCT04887571 Completed - Clinical trials for Acute Coronary Syndrome

the PrEsentation, Rationale and Impact of reperFUSION for Acute Coronary Syndromes in Cape Town and the Garden Route Health District - the PERFUSION Registry

PERFUSION
Start date: February 1, 2021
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT04861519 Completed - Stable Angina Clinical Trials

Pivotal, Single-arm Clinical Trial to Assess the Efficacy and Safety of the MedHub AutocathFFR Software Device

AutocathFFR
Start date: May 9, 2021
Phase:
Study type: Observational

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.
