NCT ID: NCT06197256 Completed - COVID-19 Clinical Trials

Cardiac Dysfunction in Critically Ill Covid-19 Patients

Start date: May 7, 2020
Phase:
Study type: Observational

We conducted an observation sub-study of the prospective randomized controlled trial "High Dose Inhaled Nitric Oxide in Acute Hypoxemic Respiratory Failure", in which we analysed the echocardiographic data collected both at baseline when patients where included and 3-5 days later for followup.

NCT ID: NCT05939089 Completed - Heart Failure Clinical Trials

Cardiovascular Assessment of Pediatric Cancer Survivors

CASPER
Start date: January 1, 2023
Phase:
Study type: Observational

The goal of this observational study is to evaluate cardiac and vascular health status of pediatric cancer survivors.

NCT ID: NCT05861115 Completed - Clinical trials for Left Ventricular Systolic Dysfunction

A Study to Evaluate Accuracy and Validity of the "Chang Gung" Ventricular Systolic Dysfunction Screening Software

Start date: April 15, 2023
Phase: N/A
Study type: Interventional

The purpose of this research is to test a software tool called the "Chang Gung" Ventricular Systolic Dysfunction screening software, which uses a 12-lead electrocardiogram to determine if a patient has left ventricular systolic dysfunction. The goal is to determine if the software can accurately identify patients with this condition, which would help doctors diagnose and treat it more effectively. The trial will involve using the software on patients and comparing its results to those obtained through echocardiograms, which are currently the gold standard for diagnosing left ventricular systolic dysfunction. Only patients who meet specific eligibility criteria will be able to participate in the trial, and the software will be administered by trained healthcare professionals. The study will help determine if the software is a useful tool for diagnosing left ventricular systolic dysfunction, which could lead to earlier diagnosis and better outcomes for patients. The research team will collect and analyze data on the accuracy of the software and its usability in clinical practice. Overall, this study will provide important information for doctors and patients about a new tool for diagnosing left ventricular systolic dysfunction.

NCT ID: NCT05650008 Completed - Clinical trials for Left Ventricular Dysfunction

Effects of Intrathecal Local Anesthetics on Left Ventricular Global Longitudinal Strain

Start date: February 1, 2023
Phase:
Study type: Observational

The objective of this study is to assess the effects of intrathecal local anesthetics on left ventricular global longitudinal strain (LVGLS) using transthoracic echocardiography (TTE).

NCT ID: NCT05630170 Completed - Clinical trials for Left Ventricular Systolic Dysfunction

The SMART-LV Pilot Study

Start date: September 13, 2023
Phase: N/A
Study type: Interventional

The goal of this pilot study is to evaluate the prospective performance of an image-based, smartphone-adaptable artificial intelligence electrocardiogram (AI-ECG) strategy to predict and detect left ventricular systolic dysfunction (LVSD) in a real-world setting.

NCT ID: NCT05317286 Completed - Clinical trials for Acute Coronary Syndrome

LVEF Prediction During ACS Using AI Algorithm Applied on Coronary Angiogram Videos

CathEF
Start date: June 1, 2022
Phase:
Study type: Observational

Left ventricular ejection fraction (LVEF) is one of the strongest predictors of mortality and morbidity in patients with acute coronary syndrome (ACS). Transthoracic echocardiography (TTE) remains the gold standard for LVEF measurement. Currently, LVEF can be estimated at the time of the coronary angiogram but requires a ventriculography. This latter is performed at the price of an increased amount of contrast media injected and puts the patients at risk for mechanical complications, ventricular arrhythmia or atrio-ventricular blocks. Artificial intelligence (AI) has previously been shown to be an accurate method for determining LVEF using different data sources. Fur the purpose of this study, we aim at validating prospectively an AI algorithm, called CathEF, for the prediction of real-time LVEF (AI-LVEF) compared to TTE-LVEF and ventriculography in patients undergoing coronary angiogram for ACS.

NCT ID: NCT05010655 Completed - Clinical trials for Cardiovascular Diseases

Low Ejection Fraction in Single Lead ECG

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

The purpose of this research is to prospectively test and validate the single-lead Low EF algorithm in outpatients in order to test the performance of a single-lead ECG based algorithm to identify people with decreased left ventricular EF.

NCT ID: NCT05010642 Completed - Clinical trials for Cardiovascular Diseases

Low Ejection Fraction in Single Lead ECG- Ochsner

Start date: August 19, 2021
Phase:
Study type: Observational

The purpose of this research is to prospectively test and validate the single-lead Low EF algorithm in outpatients in order to test the performance of a single-lead ECG based algorithm to identify people with decreased left ventricular EF.

NCT ID: NCT04957004 Completed - Clinical trials for Left Ventricular Dysfunction

Evaluation of Left Ventricular Function and Therapeutic Effect of CPAP in Patients With OSAS by 3D STE

Start date: July 22, 2018
Phase:
Study type: Observational

The changes of left ventricular function in patients with sleep apnea were studied by three-dimensional speckle-tracking echocardiography to evaluate the changes of left ventricular function after CPAP treatment

NCT ID: NCT04942353 Completed - Heart Failure Clinical Trials

Effects of Home-based Exercise Rehabilitation on Healthcare Utilization in HeartMate 3 Patients

MOVE-LVAD
Start date: October 19, 2020
Phase: N/A
Study type: Interventional

To demonstrate that home-based exercise rehabilitation (HER) compared to usual care (UC) results in a significant reduction in healthcare utilization in HeartMate 3 (HM3) left ventricular assist device (LVAD) patients.(defined as rehospitalization, VAD Clinic visits, and ER visits during the 1st year after index discharge following LVAD implantation).
