Left ventricular diastolic dysfunction and arterial occlusion in ischemic stroke related to atrial fibrillation

【Background】Left ventricular diastolic dysfunction lead to left atrial stasis and thus increases a risk of left atrial appendage thrombus in patients with atrial fibrillation. We investigated whether left ventricular diastolic dysfunction is associated with embolic burden in patients with ischem ic stroke related to atrial fibrillation.

Atrial fibrillation is the most common sustained cardiac arrhythmia in the general population. In western countries with aging populations, atrial fibrillation poses a significant health concern, as it is associated with a high risk of thromboembolism, stroke, congestive heart failure, and myocardial infarction. Thrombi are generated in the left atrial appendage, and subsequent embolism into the cerebral circulation is a major cause of ischemic stroke. Therefore, patients have a lifetime risk of stroke, and those at high risk, defined as a CHA2DS2-VASc2 (congestive heart failure, hypertension, age>75 years, diabetes mel...

Abstract Cardiogenic stroke (CS), characteristic causes of which include atrial fibrillation (AF) and right-to-left shunting due to a patent foramen ovale (PFO), has a well-known tendency to be associated with a more extensive ischemic area. This may result in severe neurological damage, and require strict life-long antithrombotic therapy. However, the fact that some patients have problems complying with the requirement for extended oral antithrombotic treatment has motivated the development of alternative approaches for stroke prevention. Heart structures such as the left atrial appendage (LAA) and PFO are potent...

This study assesses the current practices of physicians in Lebanon routinely involved in ischemic stroke (IS) management. We conducted a prospective observational study of patients hospitalized at 8 different Lebanese hospitals in the period August 1, 2015 to July 31, 2016, with a diagnosis of acute stroke. Baseline characteristics and data on diagnostic studies, as well as treatments received during hospitalization and at discharge, were collected and analyzed. Two hundred and three strokes/transient ischemic attacks (TIAs) were recorded but only 173 patients (85%) with ischemic events were included in the study. The pati...

CONCLUSIONS: In patients with kidney failure and nonvalvular atrial fibrillation, treatment with apixaban was not associated with a lower incidence of new stroke, transient ischemic attack, or systemic thromboembolism but was associated with a higher incidence of fatal or intracranial bleeding.

Authors: Zimmermann F, Landmesser U Abstract Atrial fibrillation (AF) is one of the most frequent causes of ischemic stroke. Without treatment the annual risk of ischemic stroke is on average approximately 5-6%/year in patients with atrial fibrillation, depending on the overall cardiovascular risk profile. Oral anticoagulation with new oral anticoagulants (NOAC) or vitamin K antagonists (VKA) is recommended for patients with AF and an elevated risk for stroke (CHA2DS2-VASc score ≥1); however, severe bleeding complications are potential reasons for discontinuation of this treatment. Overall, up to 30 % of the p...

In this study, we aim to quantify global cardiac microcalcification in patients at risk for cardiovascular disease as assessed by NaF uptake on PET/CT and correlate this uptake with CHADS2 and CHA2DS2-VASc scores. We hypothesize that global cardiac microcalcification will correlate positively with CHADS2 and CHA2DS2-VASc scores. Methods: We identified 40 patients at-risk of cardiovascular disease from the CAMONA trial (55±11.9 years, 22 females, 18 males). CHADS2 (0.75±0.19) and CHADS2-VASc (1.8±1.25) scores were calculated for each patient based on relevant clinical parameters pertaining to each scori...

In conclusion, more and more patients who suffer a hematuria while on oral anticoagulant therapy resume NOAC. Patients resuming NOAC have similar risks of ischemic stroke/systemic embolism and major bleeding compared with those resuming VKA.

Authors: Salášek M, Šlechtová J, Pavelk T Abstract Heparin-induced thrombocytopenia is a rare complication of treatment with both unfractionated heparin (UFH) and low molecular weight heparin (LMWH). Antibodies against the complex heparin-platelet factor 4 are the main cause of pathogenesis, resulting in the activation of thrombocytes, coagulation, endothelium, monocytes, neutrophils and subsequent highly prothrombotic state. The prothrombotic state can result not only in venous but also in arterial thrombosis at different locations (which is manifested apart from venous thromboembolic d...
