This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact

This open access book presents a wide portfolio of examples of positron emission tomography coupled with computer tomography (PET/CT) studies in various cardiac conditions in order to provide a rationale for the implementation of this technology in an array of clinical conditions. Cardiovascular diseases are a major contributor to premature morbidity and mortality worldwide. Low- and middle-income countries (LMICs) are particularly affected by cardiovascular diseases (CVDs), with more than 75% of all CVDs deaths occurring in these countries. For this reason, target 3.4 of the United Nations (UN) Sustainable Development Goals (SDGs) agenda aims at a 30% reduction in premature mortality due to non-communicable diseases (NCDs), which include CVDs, by 2030. Among CVDs, ischemic heart disease (IHD) plays an important role and, according to the Institute for Health Metrics and Evaluation (IHME), it was responsible for 15.96% of global deaths in 2017. Between 2000 and 2017, thenumber of IHD deaths worldwide increased by 0.26% per year. Several imaging tools help to non-invasively diagnose, stratify risk and guide management in cardiac disease. They include nuclear cardiology techniques, using either SPECT (single photon emission computed tomography) or PET/CT. While myocardial imaging with SPECT has been fully embraced by the cardiology community and is widely available worldwide, PET/CT introduction has been slower, due not only to its higher costs, but also to the limited availability of PET/VCT scanners, mostly utilized for oncological applications. This book is an invaluable tool for nuclear medicine physicians, cardiologists and radiologists.

Cardiovascular disease is the main cause of death in the West, and vascular disease is the most common cardiovascular clinical problem. The disease results in serious morbidity and mortality, and carries economic cost implications. While conventional risk factors are well established, and their biomarkers regularly monitored, patients may continue to suffer subclinical active disease, even in the absence of risk factors, until they present with sudden cardiac death or stroke. Early disease detection using direct imaging has shown to be more accurate in identifying vulnerable patients and unstable plaques than conventional risk factors. This IJMS issue deals with the current opinion concerning the state-of-the-art imaging technologies available for clinical applications and their unique value over the sole use of conventional risk factor analysis, in identifying vulnerable patients, recommending aggressive treatments, prognosticating, and in assessing related nutritional and environmental issues.

This special issue of JCM ‘The Prevention and Treatment of Atherosclerosis’ will walk the Readers across novel diagnostic achievements in atherosclerosis and contemporary actions towards optimizing therapy.Everything begins with diagnosis. Accurate diagnostic tools and tests are of utmost importance. Contemporary research on microparticles, non-coding RNAs, proteomic characterization, …, offers detailed molecular characteristics of athero-thrombosis.Prevention is equally important as treatment. The impact of eating habits in prophylaxis of many pathologies, including cardiovascular disease has been documented.Then new pharmacological agents. Managing hypercholesterolemia with PCSK9 inhibitors, shown great potential in efficient lipid lowering to achieve LDL-C treatment goals, as well as reduction in cardiovascular mortality and morbidity.However, therapeutic goals accomplishment requires supervision. Arising number of data support that cardiovascular risk prediction can be improved with imaging modalities displaying atheroma: carotid plaque ultrasonography, coronary calcium score, intravascular ultrasonography, and optical coherent tomography or many others.As atherosclerosis is a progressive disease, it comes the time for more radical management, including endovascular and surgical intervention. There is field for new stent and equipment technologies, new surgical and endovascular techniques, supervision of endovascular procedures with IVUS, OCT, functional flow assessment or cell therapy.From diagnosis to risk stratification, elaborated prevention models, finally to modern and optimized therapeutic intervention.
