A Case of Infiltrative Cardiomyopathy Secondary to Primary Hyperoxaluria Type 2 - Utilization of Multimodality Imaging.

Primary hyperoxaluria is a rare genetic disorder characterized by oxalate crystal deposition, including in the heart. Hyperoxaluria-associated cardiomyopathy manifests as restrictive infiltrative cardiomyopathy. We present a case of a 52-year-old male with a past medical history of type 2 primary hyperoxaluria, end-stage renal disease on hemodialysis, paroxysmal atrial fibrillation, and hypertension, who presented with dyspnea and lethargy.

Early Apixaban Use Following Stroke in Patients With Atrial Fibrillation: Results of the AREST Trial.

Background And Purpose: It is unknown when to start anticoagulation after acute ischemic stroke (AIS) from atrial fibrillation (AF). Early anticoagulation may prevent recurrent infarctions but may provoke hemorrhagic transformation as AF strokes are typically larger and hemorrhagic transformation-prone. Later anticoagulation may prevent hemorrhagic transformation but increases risk of secondary stroke in this time frame.

Protocol for AREST: Apixaban for Early Prevention of Recurrent Embolic Stroke and Hemorrhagic Transformation-A Randomized Controlled Trial of Early Anticoagulation After Acute Ischemic Stroke in Atrial Fibrillation.

Optimal timing to initiate anticoagulation after acute ischemic stroke (AIS) from atrial fibrillation (AF) is currently unknown. Compared to other stroke etiologies, AF typically provokes larger infarct volumes and greater concern of hemorrhagic transformation, so seminal randomized trials waited weeks to months to begin anticoagulation after initial stroke. Subsequent data are limited and non-randomized.
