We present a case of true spontaneous cholesterol embolisation causing acute renal failure. There was no history of vascular procedural interventions or thrombolytic therapy prior to her presentation, but the patient did have a history of difficult hypercholesterolemia and atherosclerosis. This case highlights the importance of remembering cholesterol embolisation as a potential cause of acute renal failure despite no apparent precipitant, especially with the presence of unexplained eosinophilia.

Background: About 30% of ischemic strokes do not have a clear cause, which is called cryptogenic stroke (CS). Increasing evidence suggests a potential link between CS and right-to-left shunt (RLS). RLS may lead to CS via paradoxical embolic mechanism.

In recent years, large amounts of researches showed that pulmonary embolism (PE) has become a common disease, and PE remains a clinical challenge because of its high mortality, high disability, high missed and high misdiagnosed rates. To address this, we employed an artificial intelligence-based machine learning algorithm (MLA) to construct a robust predictive model for PE. We retrospectively analyzed 1480 suspected PE patients hospitalized in West China Hospital of Sichuan University between May 2015 and April 2020.

Atherogenic Dyslipidemia Is Critically Related to Aortic Complicated Lesions in Cryptogenic Stroke.

Aims: Atherogenic dyslipidemia (AD) is regarded as a residual risk of cardiovascular diseases characterized by low high-density lipoprotein cholesterol (HDL-C) and high triglyceride (TG) levels and related to the intracranial stenosis of atheromatous thrombotic brain infarction (ATBI). Further, atherosclerosis is possibly related to another stroke subtype, including cryptogenic stroke (CS). In particular, an aortic complicated lesion (ACL) is a notable embolic source of CS, since recurrence of aortogenic brain embolism is not rare.
View Article and Find Full Text PDFBackground: Evaluated values of body mass index (BMI), waist circumeference (WC) and waist-to-hip ratio (WHR) increase the risk of stroke, but the extent to which this is mediated by hypertension, diabetes, lipid status, smoking and alcohol consumption is not fully understood.
Objective: The aim of this research is to examine the influence of modifying and non-modifying factors as well as obesity defined through BMI, WC and WHR on the occurrence of stroke.
Methods: A total of 440 subjects were included in the cohort divided in to two groups.
