Background and objectives: Stroke is the rapid onset of neurological symptoms that persist for >24 hours or death due to vascular causes. Biochemical alterations indicate stroke severity and outlook. Serum calcium has an important role in signal transduction pathways and may influence the severity of stroke in the acute stages. Serum uric acid acts as an indicator of tissue infarction. However, serum calcium, albumin and uric acid are rarely tested in acute ischemic stroke for severity and short-term prognosis.
Materials and methods: This is a 1-year, observational cross-sectional study of 65 individuals who experienced an acute ischemic stroke within 24 hours of onset. Patients with hemorrhagic stroke, chronic liver, and renal disease were excluded. At admission, serum calcium, albumin, and uric acid were measured along with the National Institute of Health Stroke Scale (NIHSS) severity. The Modified Rankin scale (MRS) grading done at the end of 1st week determined the short-term prognosis.
Results: In our 65-person study, stroke was common among 50-80-year-old patients. Participants included 45 (69.23%) males and 20 (30.77%) females. Male preponderance of the ratio 2.25:1 was observed. A total of 17 (26.15%) individuals had hypertension, 19 (29.23%) had overlapping comorbidities, six (9.23%) had diabetes, and five (7.69%) had coronary artery disease (CAD). Hypertension and diabetes did not show a significant correlation. Only low serum calcium was found to be positively correlated to NIHSS rating. Serum albumin and uric acid did not affect NIHSS severity. All three signals were unrelated to MRS.
Interpretation and conclusion: Low serum calcium exacerbates NIHSS. NIHSS was unrelated to albumin, uric acid, or demography. MRS grades were unaffected by three lab factors. In order to decrease bias and relate these three lab measures to acute ischemic stroke, large-scale prospective research is required.
