Objectives: Coronavirus disease-19 (COVID-19) is caused by severe acute respiratory distress syndrome-coronavirus-2 (SARS-CoV-2) -that can affect the cardiovascular system. The aim of our study was to assess the cardiovascular manifestations and its effect on the overall mortality among patients with severe COVID-19 who were admitted in the intensive care units (ICU).

Methods: This is a retrospective, multicenter cohort study that included all adult patients admitted to the ICU with laboratory-confirmed COVID-19 in three major hospitals in Oman between March 1, 2020, and August 10, 2020.

Results: A total of 541 patients (mean age of 50.57 ± 15.57 years; 401 [74.1%] male) were included in the study of which 452 (83.5%) were discharged and 89 (16.5%) died during hospitalization.Evidence of cardiac involvement was found in 185 (34.2%) patients, which included raised troponin (31.6%), arrhythmias (4.3%), myocardial infarctions (2.6%), or drop in ejection fraction (0.9%). High troponin of >100 ng/l was associated with higher mortality (odds ratio [OR] = 7.98; 95% confidence interval [CI]: 4.20-15.15); < 0.001). Patients with any cardiovascular involvement also had a high risk of dying (OR = 8.8; 95% CI: 4.6-16.5; < 0.001).

Conclusion: Almost a third of patients in our study had evidence of cardiovascular involvement which was mainly myocardial injury. This was associated with increased mortality.

Purpose Of Review: The present review aims to address systemic sclerosis (SSc)-associated myocardial disease, a significant cause of morbidity and mortality, by examining the mechanisms of inflammation, microvascular dysfunction, and fibrosis that drive cardiac involvement. The objective is to elucidate critical risk factors and explore advanced diagnostic tools for early detection, enhancing patient outcomes by identifying those at highest risk.

Recent Findings: Recent studies underscore the importance of specific autoantibody profiles, disease duration, and cardiovascular comorbidities as key risk factors for severe cardiac manifestations in SSc.

Nuclear Cardiology Surrogate Biomarkers in Clinical Trials.

J Nucl Med

Departments of Medicine (Division of Artificial Intelligence in Medicine), Imaging, and Biomedical Sciences, Cedars-Sinai Medical Center, Los Angeles, California;

Nuclear cardiology offers a diverse range of imaging tools that provide valuable insights into myocardial perfusion, inflammation, metabolism, neuroregulation, thrombosis, and microcalcification. These techniques are crucial not only for diagnosing and managing cardiovascular conditions but also for gaining pathophysiologic insights. Surrogate biomarkers in nuclear cardiology, represented by detectable imaging changes, correlate with disease processes or therapeutic responses and can serve as endpoints in clinical trials when they demonstrate a clear link with these processes.

Clinic of Cardiovascular Diseases named after Most Holy John Tobolsky, Moscow, Moscow, Russia.

Background: Dementia aggravates most cerebrovascular lesions, which requires differentiating the developed microcirculatory changes when making a diagnosis. We consider the features of cerebral microcirculation disorders in Alzheimer's disease (AD), distal cerebral atherosclerosis, Binswanger's disease (BD), and vascular parkinsonism (VP).

Method: The study included 1024 patients who underwent: assessment of CDR, TDR, MMSE, cerebral MRI, MRA, CT, MSCTA, scintigraphy (SG), rheoencephalography (REG), cerebral multi-gated angiography (MUGA).

Background: Small vessel disease (SVD) is a disorder of the brain's microvessels and a common cause of dementia and stroke. Evidence links normal ageing features to SVD progression, involving endothelial activation, pericyte dysfunction, BBB failure, and microglia response. Here, we aim to examine this relationship through a series of translational investigations.

Background: Cerebrovascular injury is a common pathological feature of a spectrum of neurological disorders, including traumatic brain injury (TBI), stroke, Alzheimer's disease (AD), and aging. Vascular manifestations among these conditions are similar indeed, including the breakdown of the blood-brain barrier (BBB). However, whether there is a unique molecular mechanism underlying the vascular changes among these conditions remains elusive.
