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...

Conclusions: Our results suggest that in this community-dwelling population, a higher CAA score is related to cognitive impairment and a higher risk of stroke, dementia, and death. The composite CAA score can be used to practically quantify the severity of vascular brain injury.

Written by Meyers, edits by SmithA 50-ish year old man was working construction when he suddenly collapsed. Coworkers started CPR within 1 minute of collapse. EMS arrived within 10 minutes and continued CPR and ACLS, noting alternating asystole and sinus bradycardia during rhythm checks. He received various ACLS medications and arrived at the ED with a perfusing rhythm.Initial vitals included heart rate around 100 bpm and BP 174/96. Here is his initial ECG, very soon after ROSC:What do you think?Sinus tachycardia.  There is incomplete RBBB (QRS duration less than 120 ms).  There is diffuse STD, maximal in V4-V5 a...

CONCLUSIONS: This study provides significant evidence of the association between circulating NLR and R-DWILs in spontaneous ICH patients. Patients with NLR > 6.01 at 24-48 hours after ICH ictus should be paid more attention to when evaluating R-DWILs. PMID: 31651093 [PubMed - as supplied by publisher]

Authors: Inoue T, Suematsu Y Abstract Background: In atrial fibrillation (AF) patients, the left atrial appendage (LAA) is the major source of thrombi. We assessed the hypothesis that poor contrast enhancement in the LAA during the early phase of cardiac computed tomography (CT) predicts a high risk of thrombus formation, leading to cardiogenic stroke. Methods: We studied 147 consecutive patients with chronic AF who underwent cardiac CT. Three different patterns of medium contrast enhancement in the LAA were used to categorize the stroke risk: poor, intermediate, and good enhancement pattern. Results: The C...

Conclusions. Certain types of arrhythmias such as APC, VPC, SVT and paroxysmal AF have been shown to be independently associated with the presence of ASA. PMID: 31544553 [PubMed - as supplied by publisher]

ConclusionThese results illustrate areas in which we can improve education post-stroke, including ensuring patients receive individualised information about the aetiology of their stroke, risk factors and the importance of new medications. It also highlights the importance of ensuring advice regarding driving is clearly explained and documented.

ConclusionPatients admitted to AMU with suspected TIAs had relevant imaging and tests completed as per guidelines. 89 % had US Carotid Dopplers which were on average done 33h from admission. 58% of patients had inpatient heart monitoring. The average length of stay was 3 days but three patients stayed in AMU for up to 5 days. Protected imaging slots for AMU would expedite investigations and reduce inpatient stay.

Background: Previous studies have investigated the association between a single marker of cerebral small vessel disease (SVD) and hemorrhagic transformation (HT). However, the effect of the total SVD burden on HT has not been evaluated yet. We aimed to investigate the association between the total SVD score and HT in ischemic stroke patients with atrial fibrillation (AF) and/or rheumatic heart disease (RHD). Methods: Ischemic stroke patients with AF and/or RHD admitted within 7 days after onset were enrolled at two hospitals in China. The total SVD score was based on the presence of lacunes, extensive white matter hyperin...
