Molecular Imaging of Fibroblast Activity After Myocardial Infarction Using a 68Ga-Labeled Fibroblast Activation Protein Inhibitor, FAPI-04

Conclusion: 68Ga-FAPI-04 represents a promising radiotracer for in vivo imaging of post-MI fibroblast activation. Noninvasive imaging of activated fibroblasts may have significant diagnostic and prognostic value, which could aid clinical management of patients after MI.

The field of medical AI is buzzing. More and more companies set the purpose to disrupt healthcare with the help of artificial intelligence. Given how fast these companies come and go, it can prove to be hard to stay up-to-date with the most promising ones. Here, I collected the biggest names currently on the market ranging from start-ups to tech giants to keep an eye on in the future. To further help you keep up with what A.I. brings to medicine, The Medical Futurist team made an easy-to-digest e-book about just that. I highly encourage you to read it and would love to hear about your thoughts! Artificial Intelligence has ...

In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple inter...

Discussion, “Top 5 Things You Need to Know about the Implantable Internet of Things." Brian Chapman, partner and leader of ZS’s medtech practice of ZS, attributes today’s focus on data to the intersection of two important things: "A general recognition that understanding more and connecting actions with outcomes will provide feedback and understanding that will drive standards of care. This is not new, but as capabilities rise in data collection, aggregation, and synthesize rise, and coupled with machine learning, the promise of data in healthcare is becoming ...

Abstract Background: Cardiac dysfunction and cardiovascular (CV) events are prevalent among patients with chronic kidney disease (CKD) without overt obstructive coronary artery disease (CAD) but the mechanisms remain poorly understood. Coronary microvascular dysfunction (CMD) has been proposed as a link between abnormal renal function and impairment of cardiac function and CV events. We sought to investigate the relationships between CKD, CMD, cardiac dysfunction and adverse CV outcomes. Methods: Patients undergoing cardiac stress positron emission tomography (PET), echocardiogram and renal function ascertainment ...

This study clearly goes against what has been the common wisdom for the last 30, 40 years” and may lead to less testing and invasive treatment for such patients in the future, said Dr. Glenn Levine, a Baylor College of Medicine cardiologist with no role in the research. Some doctors still may quibble with the study, but it was very well done “and I think the results are extremely believable,” he said. About 17 million Americans have clogged arteries that crimp the heart’s blood supply, which can cause periodic chest pain. Cheap and generic aspirin, cholesterol-lowering drugs and blood pressure medic...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

This study aimed to investigate the effects of exercise training at different intensities in rats with HF. Methods. Rats underwent myocardial infarction or sham operations and were divided into three subgroups: sedentary, moderate intensity, or high intensity. The impact of HF and 6 weeks of exercise training on energy metabolism was evaluated by 31P magnetic resonance spectroscopy and mitochondrial respirometry. The concentrations of PCr, ATP, and Pi were quantified by magnetic resonance spectroscopy. VO2max was measured by treadmill respirometry. Results. Exercise training increased VO2max in sham and HF. PCr/ATP ratio w...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

AbstractPurpose of ReviewDespite advances in medical and surgical therapy, some patients after a myocardial infarction still develop heart failure, a devastating disease that has a high rate of morbidity and mortality. Differences in the immune response to the myocardial damage may affect the healing process. Molecular imaging enables the interrogation of immune cell subsets that can aid or impair left ventricular recovery post-myocardial infarction. Visualization of patient-specific differences in the cellular and molecular process among patients post-myocardial infarction may lead to the development of personalized thera...
