Filter by:This observational study aims to learn about the preliminary exploration of 99mTc-FAPI imaging in heart diseases and its potential application. Participant involves patients with myocarditis, pulmonary hypertension, arrhythmia, myocardial infarction, dilated cardiomyopathy, and cardiac tumors, health conditions may also studied as control. The main questions it aims to answer are 1, radionuclide 99mTc labeled fibroblast-activated protein inhibitors (99mTc-FAPI) imaging in the use of cardiac diseases and its limitations. 2, the performance in subjects with different control of hypertension to evaluate myocardial injury and fibrosis for providing a molecular biological basis for the study of diseases and mechanisms. Participants will undergo 99mTc-FAPI imaging by Single-photon emission computed tomography (SPECT) and record their cardiac disease characterization and treatment.
This is a prospective, randomized, open-label, active drug controlled clinical trial that aims to compare the effects of henagliflozin or metformin on myocardial tissue level characteristics in type 2 diabetes patients with obesity. Eligible subjects with type 2 diabetes before randomisation and fulfilling all of the inclusion criteria and none of the exclusion criteria will be randomised in a 1:1 ratio to henagliflozin 10 mg once a day or metformin 1000 mg twice a day and treated for 24 weeks. The study includes five visits.
Elucirem (Gadopiclenol) is a new macrocyclic gadolinium-based contrast agent (GBCA) with high relaxivity indicated for use in adults and children aged 2 years and older for contrast-enhanced magnetic resonance imaging. The product was approved in 2022 by FDA to be used to detect and visualize lesions with abnormal vascularity in the central nervous system (brain, spine and associated tissues) and the body (head and neck, thorax, abdomen, pelvis, and musculoskeletal system). However, given its at least twofold higher relaxivity than other GBCAs, the performance of Elucirem in cardiac MR (CMR) has yet to be demonstrated. The hypothesis for the study: Half dose (0.05mmol/kg) Elucirem is not inferior to double dose (0.2 mmol/kg) Dotarem in the myocardial scar assessment. All participants will be selected from the investigators previous CMR study cohort with double-dose Dotarem T1 mapping and LGE images. Ten participants without scars will be recruited for the Phase I dose evaluation. Five for 0.05 mmol/kg and five for 0.075 mmol/kg. The investigators have identified 15 participants with LGE findings from double-dose Dotarem CMR acquired in the years 2021, 2022, or earlier years. This study was performed in August 2022. The same protocol will be used for single-dose Elucirem.
Injury to the heart, which may occur following a heart attack or owing to the mechanical effect of high blood pressure, leads to scarring (fibrosis) of the heart muscle. Fibrosis of the muscle can cause impaired pumping of the heart, which can lead to heart failure, and the abnormal conduction of electrical signals through the heart. This may in turn lead to abnormal, potentially fatal, heart rhythms. Currently, scarring of the heart muscle cannot be reversed and is generally progressive. A previous clinical study found that participants who received injections of immunomodulatory progenitor cells (iMP cells, "Heartcel") showed a reversal of heart muscle scarring when the cells were injected into heart muscle during coronary artery bypass graft (CABG) surgery. However, the previous trial was a small scale study and did not have a control group. The aim of this study is to perform a larger scale investigation with 50 participants compared to the previous trial of 11, and split the 50 participants into two groups - a test group and a control group, so that a direct comparison may be made between the two groups.
