Predicting Hemorrhagic Transformation of Acute Ischemic Stroke: Prospective Validation of the HeRS Score

Abstract: Hemorrhagic transformation (HT) increases the morbidity and mortality of ischemic stroke. Anticoagulation is often indicated in patients with atrial fibrillation, low ejection fraction, or mechanical valves who are hospitalized with acute stroke, but increases the risk of HT. Risk quantification would be useful. Prior studies have investigated risk of systemic hemorrhage in anticoagulated patients, but none looked specifically at HT. In our previously published work, age, infarct volume, and estimated glomerular filtration rate (eGFR) significantly predicted HT. We created the hemorrhage risk stratification (HeRS) score based on regression coefficients in multivariable modeling and now determine its validity in a prospectively followed inpatient cohort. A total of 241 consecutive patients presenting to 2 academic stroke centers with acute ischemic stroke and an indication for anticoagulation over a 2.75-year period were included. Neuroimaging was evaluated for infarct volume and HT. Hemorrhages were classified as symptomatic versus asymptomatic, and by severity. HeRS scores were calculated for each patient and compared to actual hemorrhage status using receiver operating curve analysis. Area under the curve (AUC) comparing predicted odds of hemorrhage (HeRS score) to actual hemorrhage status was 0.701. Serum glucose (P

AbstractPatients with atrial fibrillation (AF) who suffer an acute ischemic stroke are at risk for both hemorrhagic transformation and recurrent ischemic stroke in the acute post ‐stroke period. Oral anticoagulants are recommended for secondary stroke prevention in patients with AF. The optimal time to initiate anticoagulant therapy after acute ischemic stroke in patients with AF is uncertain. There is concern that early initiation increases the risk of hemorrhagic transfo rmation, whereas delayed initiation leaves the patient at risk for recurrent ischemic stroke. In this article, we provide a review of the risk of hemo...

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...

This study evaluated and compared the safety outcomes of DOACs versus warfarin in patients with non-valvular AF and concomitant CKD. Patients in our health system with AF prescribed oral anticoagulants during 2010 to 2017 were identified. All-cause mortality, bleeding, and hemorrhagic and ischemic stroke were evaluated based on degree of renal impairment and method of anticoagulation.

The management of atrial fibrillation and deep venous thrombosis has evolved with the development of direct oral anticoagulants (DOAC), and oral anticoagulant (OAC) might influence the development or clinical course in both ischemic and hemorrhagic stroke. However, detailed data on the differences between the effects of the prior prescription of warfarin and DOAC on the clinical characteristics, neuroradiologic findings, and outcome of stroke are limited.

AbstractThe role of non-vitamin K antagonist oral anticoagulants (NOACs) in stroke prevention remains unclear in Asian patients with atrial fibrillation (AF). Therefore, we performed a meta-analysis to compare the efficacy and safety outcomes of NOACs in Asian patients with AF from the real-world settings. The PubMed and Embase databases were systematically searched to identify eligible observational studies until June 2019. The odds ratios (OR) and 95% confidence intervals (CIs) were calculated and then pooled by a random-effects model. A total of 18 observational studies were included. Compared with warfarin, dabigatran ...

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]
