Improved Prediction of Functional Recovery After Revascularisation Using Combined Assessment of Myocardial Ischaemia and Viability by CMR - Pilot Study

Start date: January 26, 2019
Phase:
Study type: Observational

The study will investigate whether a new high resolution heart Magnetic Resonance Imaging scan, combining assessment of ischemia and viability by perfusion and Late Gadolinium Enhancement -Cardiac Magnetic Resonance is superior to Late Gadolinium Enhacement imaging alone in predicting functional recovery following revascularisation.

NCT ID: NCT03607669 Recruiting - Clinical trials for Dilated Cardiomyopathy

Manganese-Enhanced Magnetic Resonance Imaging of the Myocardium

Start date: June 1, 2018
Phase:
Study type: Observational

Scanning the heart using magnetic resonance imaging (MRI) enables detailed assessment of its structure and function. MRI can give more detailed information about the heart by using a contrast 'dye' that is injected into a vein during the scan. This can highlight abnormal areas within the heart. Current contrast dyes help identify scarring within the heart, which is useful in people who have had heart attacks. The investigators plan to test new contrast dye containing manganese, which works differently to current agents. They believe it will provide unique insight into how the heart works. There are many different causes of heart problems and the investigators plan to use this new contrast agent to scan three patient groups; (i) heart disease caused by heart attacks, (ii) heart disease with abnormal thickening of the heart muscle, and (iii) heart disease where the heart becomes stretched and enlarged. Healthy volunteers will be scanned for comparison. The study will be carried out at the Royal Infirmary of Edinburgh. Adults between 18 and 65 with stable heart failure can be considered. Women who may be pregnant are unable to participate, as is anyone who has some types of metal in their body, as these people can't have an MRI scan safely. All participants will have 2 MRI scans lasting about an hour each, at least 2 days apart. Some participants will be have 4 MRI scans, over a longer time period. The investigators will also take some blood samples and record a tracing of the heart rhythm and will ensure there are no abnormal side-effects by telephone follow up. The investigators believe this new agent has potential to better measure disease in the heart, improve the ability to establish the cause of heart disease and help monitor the disease over time as well as guide future treatment for individual patients.

NCT ID: NCT03590925 Recruiting - Clinical trials for Ischemic Cardiomyopathy

Evaluation of the Improvement of Primary Prevention in Ischemic Cardiomyopathy Patients Using New Screening and Referring System (Advance-ICM)

Start date: March 21, 2018

The patients who undergo ICD(implantable cardioverter defibrillator) implantation for the primary prevention of sudden cardiac death with severe LV(left ventricle) dysfunction (ejection fraction ≤ 40%) by ICM(idiopathic cardiomyopathy). Indications for ICD implantation for primary prevention in accordance with 2016 revised Korean indication guideline on ICD implantation - FU LVEF(Left Ventricular Ejection Fraction) ≤ 30% (at least 40 days post-myocardial infarction) - FU LVEF 31~35%, NYHA(the New York Heart Association) class II, III (at least 40 days post-myocardial infarction) - FU LVEF ≤ 40%, NSVT(non-sustained ventricular tachycardia) (Holter), inducible VF(ventricular flutter) or sustained VT(ventricular tachycardia) at electrophysiological study (at least 40 days post-myocardial infarction)

The Effect of Low LEVel TrAgus STimulation on the Electrophysiological Substrate of Patients With Ischemic CardioMyopathy Substrate of Subjects With Ischemic CardioMyopathy

ELEVATE-ICM
Start date: May 25, 2018
Phase: N/A
Study type: Interventional

Patients with ischemic cardiomyopathy (left ventricular ejection fraction <35%) and heart failure who already have an implantable device with an atrial lead (dual chamber defibrillator or biventricular defibrillator) will undergo sequentially 1. Sham low level tragus stimulation (LLTS) (5min), 2. Active LLTS at 5Hz (15min) and 20Hz (15min) and 3. Active LLTS group with atrial pacing at 100bpm at 5Hz (15min) and 20Hz (15min). The latter is required to examine the effect of LLTS on RA independent of heart rate. Repolarization alternans will be measured by analyzing a regular 12-lead ECG using a custom-made software.

Ablation at Virtual-hEart pRedicted Targets for VT

AVERT-VT
Start date: October 20, 2018
Phase: N/A
Study type: Interventional

The goal of this study is to test the efficacy of the new imaging/simulation ("virtual heart") approach for determining the optimal ablation sites in patients with VT, which render post-infarction VT non-inducible. The study will test both the acute outcome of the ablation procedure, and the effect the use of the predicted targets has upon procedure time.

NCT ID: NCT03531151 Recruiting - Heart Failure Clinical Trials

MRI of Myocardial Infarction

MRIMI
Start date: April 1, 2018
Phase:
Study type: Observational [Patient Registry]

Heart failure (HF) is an enormous health burden affecting approximately 5.1 million people in the US and is the cause of 250,000 deaths each year. Approximately 50% of HF is caused by myocardial ischemia and requires immediate restoration of coronary blood flow to the affected myocardium. However, the success of reperfusion is partly limited by intramyocardial hemorrhage, which is the deposition of intravascular material into the myocardium. Hemorrhagic reperfusion injury has high prevalence and patients have a much greater risk of adverse left ventricular remodeling, risk of fatal arrhythmia, impaired systolic function and are hospitalized at a greater rate. Recent magnetic resonance imaging techniques have improved assessment of reperfusion injury, however, the association between MRI contrasts and reperfusion injury is highly unclear, and lacks specificity to IMH. Improved imaging of IMH and accurate knowledge about its spatial and temporal evolution may be essential for delivery of optimal medical therapy in patients and critical to identify patients most at risk for adverse ventricular remodeling. The overall goal is to investigate the magnetic properties of hemorrhage and develop MRI techniques with improved specificity to hemorrhage. New MRI techniques permit noninvasive assessment of the magnetic susceptibility of tissues and can target tissue iron. Therefore, the investigators hypothesize that MRI imaging of myocardial magnetic susceptibility can map hemorrhagic myocardium. The investigators will perform a longitudinal observational study in patients after reperfusion injury to validate these methods, compare the methods with conventional MR contrasts and develop MR methods for imaging humans.
