Cardiac Imaging and Nuclear Medicine for Structural Heart Disease
This community focuses on the diagnosis and characterization of structural heart conditions using advanced imaging techniques, specifically cardiac magnetic resonance and nuclear perfusion scans, to assess myocardial health and coronary artery disease.
The work centers on the application of magnetic resonance imaging (MRI) and computed tomography (CT) to evaluate specific pathologies such as hypertrophic cardiomyopathy, dilated cardiomyopathy, and cardiac amyloidosis. Recurring themes include the assessment of myocardial perfusion, the detection of myocardial fibrosis via late gadolinium enhancement, and the quantification of coronary artery calcium. The research also addresses the management of arrhythmias, including atrial fibrillation and premature ventricular contractions, and the technical aspects of cardiac lead extraction. These methods are used to determine prognostic value and guide clinical decision-making for patients with acute myocardial infarction, heart failure, and other chronic cardiovascular conditions.
The community represents a significant share of research involving specific imaging agents, accounting for 16.8% of all thallium research and 13.8% of technetium research. It also constitutes 11.2% of gadolinium research, reflecting the heavy reliance on these contrast agents in the imaging protocols described.
The community comprises 74,102 papers, primarily published in the Journal of Nuclear Cardiology, the Journal of the American College of Cardiology, and JACC: Cardiovascular Imaging.
Recent work includes the use of opportunistic coronary artery calcium detection on noncardiac chest CT scans for disease prevention, the application of digital twin-guided ablation for ventricular tachycardia, and updated consensus statements on multi-modality imaging for hypertrophic cardiomyopathy.
