BACKGROUND Relationship between serum uric acid and cardiovascular system has been recognised since years. High-sensitivity C-reactive protein (hs-CRP) is a known risk factor for cardiovascular and cerebrovascular events. The role of uric acid as a risk factor for vascular disease and acute stroke is controversial and there is little information about it.1 It is unclear as to whether high uric acid concentrations promote or protect against the development of cerebrovascular disease, or simply

As serum hs-CRP is an established risk factor for stroke, its positive correlation with serum uric acid levels would suggest that high serum uric acid could predict stroke risk. Also, it would prove to be a more cost-effective investigative tool in our present set up. METHODS In this cross-sectional study, we assessed 100 patients admitted with acute stroke in Victoria and Bowring and Lady Curzon Hospital from October 2016 to November 2018. Clinical records, routine investigations, radiological imaging, serum uric acid and hs-CRP of the patients were investigated. RESULTS Majority of the patients (33 %) belonged to the age group of > 70 yrs., followed by 61 - 70 yrs. (26 %). 69 % of the patients were males and 31 % were females. 67 % of them were hypertensive and 32 % were diabetic. 91 % had an hs-CRP level of > 3.0 mg / L and 8 % had hs-CRP levels between 1.0 and 3.0 mg / L. None of the female patients had a serum uric acid value > 6.5 mg / dL and none of the male patients had a uric acid level of > 7.0 mg / dL. There was a correlation between serum uric acid levels and serum hs-CRP levels in patients ≤ 50 yrs. of age. There was no correlation between serum hs-CRP levels and serum uric acid levels in patients more than 50 yrs. of age. CONCLUSIONS Our study showed that stroke is most common in persons > 70 yrs. of age and is more common in males compared to females. Hypertension is an independent risk factor for stroke. hs-CRP is a well-established risk marker for stroke, being raised in majority of stroke patients. Serum uric acid is not raised in all patients of acute stroke. So, it cannot be used as a risk marker for stroke. KEY WORDS hs-CRP, Serum Uric Acid, Acute Stroke
