NCT ID: NCT05583786 Recruiting - Clinical trials for Chronic Coronary Syndrome

Intracoronary ECG ST-segment Shift Remission Time During Reactive Coronary Hyperemia

t-icECG
Start date: June 1, 2022
Phase:
Study type: Observational

This study evaluates a new diagnostic approach based on intracoronary electrocardiogram (icECG) ST-segment shift remission time, denoted as τ-icECG (τ=tau, i.e., the remission half-time fitted by an exponential function to the disappearing ST-segment shift), to be used for PCI guidance.

NCT ID: NCT04914455 Recruiting - Fluid Overload Clinical Trials

Transhepatic Echography for Fluid Responsiveness After Cardiovascular Surgery

THEFRACS
Start date: December 8, 2020
Phase:
Study type: Observational

Fluid expansion in critically ill patients following high risk surgery may induce fluid overload and worse outcome. Several tools have been developped to predict fluid responsiveness in such situation in order to avoid inappropriate fluid administration but with several limitations. Inferior vena cava (IVC) distensibility is one of those tools which has the advantage to be non-invasive, dynamic and safe, is usually measured by subcostal (SC)approach. In post surgical setting this acess is limited du to practical reasons (scar, dressing...), therefore a transhepatic (TH) approach is used but has not been validated as a fluid responsiveness prediction tool. The correlation between SC approach with the TH approach vary according to studies. Therefore the performances, the threshold identified for SC approach can not be translated to the TH approach. Further, fluid congestion status measured before IVC analyses, may be a useful confounder and safety endpoint for fluid responsiveness interpretation. The primary objective of this study is therefore to study the performance of the IVC measured using TH approach (IVCth) in predicting of fluid responsiveness defined as an increased of 10% and over of stroke volume. Secondary objectives intend to analyse the correlation between TH and SC approaches, to compared their performances for fluid responsiveness prediction, and to analyse the weight of venous congestion on fluid responsiveness prediction.

NCT ID: NCT04019535 Recruiting - Clinical trials for Coronary Artery Disease

Diastolic Hyperemia Free Index for Assessment of Moderate Coronary Stenoses

DFRiFR
Start date: August 22, 2019
Phase:
Study type: Observational

A total of 106 subjects will be enrolled at up to 3 sites. Initial enrollment will occur at Washington University only. After 15 subjects have been enrolled at the primary site and no serious adverse events or protocol events have occurred the additional sites will be trained and added to enrollment.

NCT ID: NCT03230760 Recruiting - Breast Engorgement Clinical Trials

Acupuncture for Breast Engorgement During Lactation

Start date: July 18, 2017
Phase: N/A
Study type: Interventional

Breast engorgement which may manifest swell, throb, and cause mild to extreme pain is the common difficulty for breast feeding woman. It occurs in the mammary glands due to expansion and pressure exerted by the synthesis and storage of breast milk and it usually happens when the breasts switch from colostrums to mature milk. However, engorgement can also happen if lactating women miss several nursing and not enough milk is expressed from the breasts. It can be exacerbated by insufficient breastfeeding and/or blocked milk ducts. Engorgement may lead to mastitis and untreated engorgement puts pressure on the milk ducts, often causing a plugged duct. According the meridian theory, the investigators propose the acupuncture treatment for patients of breast engorgement. The investigators will include 60 patients and measure the acupuncture effect. The inclusion criteria are women with breast engorgement and 20 years old or older. Exclusion standards are patients with: 1. diabetes mellitus 2. Psychological disease or mental illness 3. Fever > 38 degrees Celsius 4. Mastitis 5.analgetics or anti - inflammatory agents used 6. ultrasound therapy applied

NCT ID: NCT02183779 Recruiting - Cold Clinical Trials

PORH and Response to Cold in Raynaud's Phenomenon.

REFRAIN
Start date: June 2014
Phase: N/A
Study type: Interventional

The main objective of the study is to determine if implication of epoxy-eicosatriénoïc acids (EETs) and NO during cutaneous post-occlusive hyperemia differs between patients with Raynaud phenomena and healthy volunteers, by studying hyperaemic postocclusive response after microinjection of fluconazole and L-NMMA at the dorsal side of the fingers.
