Atrial FDG uptake linked to ischemic stroke in patients without atrial fibrillation
Source: Journal of Nuclear Cardiology - April 26, 2022 Category: Nuclear Medicine Source Type: research

Association of atrial 18F-fluorodeoxyglucose uptake and prior ischemic stroke in non-atrial fibrillation patients
ConclusionsThis study identified an association between atrial FDG activity and a history of ischemic stroke and atrial cardiomyopathy in non-AF individuals. Further longitudinal study is warranted to demonstrate their causal relationship.

Correlation of Global Cardiac Microcalcification with CHADS2and CHADS2-VASc Scores in Individuals At-risk for Cardiovascular Disease as Assessed by NaF-PET/CT
Conclusions: Global cardiac NaF uptake on PET/CT correlated positively with both CHADS2 and CHA2DS2-VASc scores. Our data provides further evidence to support the association of these scoring systems with cardiac atherosclerotic burden.

FDG atrial uptake is associated with an increased prevalence of stroke in patients with atrial fibrillation
ConclusionsThis study shows a significant correlation between FDG atrial uptake and AF. While inconsistent, this pattern seems to be associated with an increased prevalence of cardioembolic stroke.

Safety of vasodilator stress myocardial perfusion imaging in patients with elevated cardiac biomarkers
Conclusion In the setting of elevated troponin, serious complications associated with either exercise or vasodilator stress testing appear to be relatively rare with no increased risk attributable to a particular vasodilator agent.

Risk stratification for large artery or chronic coronary artery disease-related ischemic stroke in octogenarians undergoing exercise stress myocardial perfusion imaging: A cohort study
Conclusion Exercise-MPI in octogenarians can provide risk stratification markers for LACCIS.

Left atrial enlargement increases the risk of major adverse cardiac events independent of coronary vasodilator capacity
Conclusion LAE and reduced CFR are related but distinct cardiovascular adaptations to atherogenic risk factors. LAE is a risk marker for MACE independent of clinical factors and left ventricular volumes; individuals with LAE may be at risk of MACE despite normal coronary vascular function.
