Blood Viscosity and its Clinical Implications in Ischemic Stroke and Chronic Heart Failure: Insights from a Case Report

Background: Blood viscosity has received increased attention as a potential predictor of ischemic stroke risk, particularly in patients with chronic heart failure (CHF). Despite the importance of this link, there has been a notable paucity of comprehensive research on the subject. Hence, the major goal of this study was to shed light on the potential importance of blood viscosity in individuals with ischemic stroke and CHF. Case Presentation: An 85-year-old male was presented to the emergency department after three days of gradually decreasing consciousness. His medical history included hypertension and CHF. His Glasgow Coma Scale (GCS) was determined to be E2M5V3, and he displayed evidence of upper motor neuron facial palsy as well as right hemiparesis. The clinical assessment scores, which included the NIHSS and mRS, were 10 and 4, respectively. MRI imaging confirmed the existence of several acute infarctions. Other diagnostic procedures, including an x-ray, revealed cardiomegaly and echocardiographic findings were compatible with grade I diastolic dysfunction. His blood viscosity was 8.19 cP, which was much higher than normal. The patient was diagnosed with ischemic stroke, CHF, and hyperviscosity based on these findings. Despite a small increase in blood viscosity to 8.16 cP after a six-day treatment session, the patient showed significant clinical improvement. Unfortunately, he was readmitted immediately after being discharged and died three days later. Conclusion: This case demonstrates the importance of blood viscosity in the evaluation and prognosis of patients with ischemic stroke and CHF.
