Contrast RISK (Reducing Injury Sustained by Kidneys)

Contrast RISK
Start date: January 22, 2018
Phase: N/A
Study type: Interventional

Diagnostic and therapeutic cardiac catheterization procedures are important interventions to reduce the risk of death, avoid future cardiovascular events, and improve quality of life of people with heart disease. However, exposure to the radiocontrast dyes required for these procedures can lead to contrast-induced acute kidney injury (CI-AKI); a common and costly complication. There are accurate ways to identify patients at increased risk of this complication and strategies to prevent CI-AKI. This involves ensuring that patients who are at risk have procedures done with the minimum amount of X-ray contrast dye required, and that they receive optimal intravenous fluids at the time of the procedure. This study will evaluate the implementation of a strategy where computerized decision support tools are used to help doctors identify patients at risk of CI-AKI, as well as make decisions about how much contrast dye to use and how much intravenous fluid to provide to patients who are identified at risk of CI-AKI in cardiac catheterization.

NCT ID: NCT03447938 Enrolling by invitation - Clinical trials for Coronary Artery Disease

The Minimally Invasive Coronary Surgery Compared to STernotomy Coronary Artery Bypass Grafting Trial

Start date: May 18, 2018
Phase: N/A
Study type: Interventional

MICS CABG (Minimally invasive coronary surgery), where coronary artery bypass grafting (CABG) is completed through a small incision over the left chest, has evolved to become a safe and less invasive alternative to conventional sternotomy CABG. Several observational studies have suggested significantly shorter time to return to physical activity for MICS CABG patients compared to sternotomy CABG patients. A randomized study is warranted to validate these findings, provide higher level of evidence, and potentially lead to changes in practice. The MIST Trial is a multi-centre, prospective, open label, randomized control trial comparing quality of life and recovery in the early post-operative period, between patients undergoing MICS CABG versus patients undergoing sternotomy CABG. Patients referred for isolated CABG for multi-vessel coronary artery disease and deemed technically suitable for sternotomy CABG as well as for MICS CABG are considered for enrollment into the trial. Quality of life questionnaires (The SF-36, Seattle Angina Questionnaire and EQ-5D-5L) will be used to assess the quality of life and recovery in patients undergoing sternotomy CABG or MICS CABG at 1 month, 3 months, 6 months and 12 months follow up.

NCT ID: NCT03437616 Enrolling by invitation - Clinical trials for Coronary Heart Disease

Cardiovascular Rehabilitation - Effectiveness of the Tulppa Program

Start date: February 2018
Phase: N/A
Study type: Interventional

This study investigates the effectiveness of a Finnish Tulppa outpatient rehabilitation program. Tulppa is a group-based secondary prevention program for patients with vascular diseases. The program is developed by the Finnish Heart Association. The intervention is implemented at the local primary health care centers in 12 health districts in Finland. A longitudinal controlled study is used to investigate the effects of the intervention on participants' level of cardiovascular risk factors (e.g. lipids, blood pressure, body mass index), functional capacity (e.g. 6 minute walk test), life style as well as psychosocial factors (e.g. smoking, diet, physical activity, health-related quality of life and depression). The data will be collected at baseline (i.e. before the intervention), and 6 and 12 months after the intervention started. The participants (n = 300) are patients diagnosed with coronary heart disease. The study group (n = 150) is recruited from participants of Tulppa rehabilitation in two health care districts (Pirkanmaa and Southern Karelia). The control group (n = 150) is recruited from two health care districts (Turku and Hyvinkää) that do not provide Tulppa rehabilitation.

NCT ID: NCT03329469 Enrolling by invitation - Clinical trials for Coronary Artery Disease

The Value of CT-FFR Compared to CCTA or CCTA and Stress MPI in Low to Intermediate Risk ED Patients With Toshiba CT-FFR

Start date: April 18, 2018
Phase: N/A
Study type: Interventional

Coronary Computed Tomography Angiogram (CCTA) is a non-invasive imaging modality that has high sensitivity and negative predictive value for the detection of coronary artery disease (CAD). The main limitations of CCTA are its poor specificity and positive predictive value, as well as its inherent lack of physiologically relevant data on hemodynamic significance of coronary stenosis, a data that is provided either by non-invasive stress tests such as myocardial perfusion imaging (MPI) or invasively by measurement of the Fractional Flow Reserve (FFR). Recent advances in computational fluid dynamic techniques applied to standard CCTA are now emerging as powerful tools for virtual measurement of FFR from CCTA imaging (CT-FFR). These techniques correlate well with invasively measured FFR [1-4]. The primary purpose of this study is to evaluate the incremental benefit CT-FFR as compared to CCTA in triaging chest pain patients in emergency settings who are found to have obstructive CAD upon CCTA (generally >= 30% stenosis). Invasive FFR and short term clinical outcomes (90 days) will be correlated with each diagnostic modality in order to evaluate positive and negative predictive value of each. Patients will undergo a CCTA, as part of routine emergency care. If the patient consents to participate in the study, the CCTA study will be assessed by Toshiba Software, to provide a computerized FFR reading, based on the CCTA study. If the noninvasive FFR diagnosis indicates obstructive disease, the patient will undergo cardiac catheterization with invasive FFR. As CCTA utilization increases, the need to train additional imaging specialists will increase. This study will assess the capability of FFR-CT to enhance performance on both negative and positive predictive value for less experienced readers by providing feedback based on CT-FFR evaluation. If the use of CT-FFR improves accuracy of CCTA, as compared to the gold standard, (Invasive FFR), use of CT-FFR can potentially enhance performance for less experienced readers.

NCT ID: NCT03096158 Enrolling by invitation - Clinical trials for Coronary Artery Disease

Cardiac and Endothelial Function Response to Early Exercise Training After Coronary Artery Bypass Surgery

Start date: April 1, 2017
Phase: N/A
Study type: Interventional

Background: Coronary artery bypass grafting (CABG) due to coronary artery disease (CAD) is one of the main surgical procedures performed in the area of cardiology. Individuals undergoing CABG present sarcopenia, decreased muscle strength of the lower limbs, decreased respiratory muscle strength and dyspnea due to immobility in the bed and the inherent conditions of the disease itself. Cardiorespiratory rehabilitation techniques are rarely used with measurement in hospitals and can greatly favor an early and effective reestablishment to this population in several parameters. Objective: To evaluate the effect of functional electrical stimulation (FES), ventilatory muscle training (TREMVEN), early aerobic training (AERO) and isometric handgrip training (ISO) on the functional capacity, endothelial function and cardiac parameters of individuals undergoing CABG. Methods: In a randomized clinical trial, volunteers will be allocated into four groups: EEF, TREMVEN, AERO or ISO in the preoperative period of CABG. After 48 hours (postoperative midway) of the surgery, the protocol will begin until after hospital discharge. The endpoints evaluated will be: functional capacity, respiratory muscle strength, systolic and diastolic function, arterial endothelial function, inflammatory profile and plasma levels of vascular endothelial growth factor (VEGF). Scientific contributions: Phase 1 cardiorespiratory rehabilitation with alternative interventions may provide an increase in functional capacity, strengthening of respiratory muscles, improvement in cardiac and endothelial functions, as well as increased systemic VEGF levels (myocardial revascularization) and improvement of the inflammatory profile, effectively forwarding the individuals to the rehabilitation phase 2.
