About this Research Topic
Ischemic stroke workup may include brain imaging scans like CT or MRI, laboratory analysis, transcranial and carotid ultrasound and/or CT angiogram/magnetic resonance angiogram, and electrocardiogram and transthoracic echocardiogram or transesophageal echocardiography to evaluate heart embolic sources. However, in cryptogenic stroke, these tests yield no conclusive results about the source of the clot.
Identifying the cause of an ischemic stroke is critical to prevent recurrent strokes, and the estimated risk of recurrence of cryptogenic stroke is 30% at 10 years. Therefore, the treatment strategy in the absence of an identifiable case mainly involves general stroke prevention measures, including antiplatelet drugs, anticoagulants, or statins, in conjunction with lifestyle changes like controlling blood pressure and cholesterol, quitting smoking, and maintaining a healthy diet and regular exercise.
The term 'cryptogenic' implies ambiguity and heterogeneity, prompting researchers to delve deeper to uncover hidden causative factors. It's a dynamic area of investigation, from exploring potential cardiac sources through prolonged cardiac monitoring (Paroxysmal Atrial Fibrillation), detecting embolic atrial cardiopathy and substenotic arterial diseases, to examining hypercoagulable states by occult malignancy. Significant progress is being made in understanding cryptogenic ischemic stroke, and the unveiling of these concealed causes allows for a more targeted treatment approach, ultimately leading to reduced recurrence rates and improved patient outcomes.
