Abstract
Background:: Calcium is known to be major mediator in ischemic neuronal cell death. Recent studies have shown that elevated serum calcium levels at admission in patients with stroke have been associated with less severe clinical deficits and with better outcomes. Aim:: The aim of this to determine the correlation between serum calcium (total, corrected, and ionized) and infarct size (IS) in patients with acute ischemic stroke. Materials and Methods:: Data were collected from 61 patients presenting with acute ischemic stroke from May 2015 to April 2016 at a tertiary care institute in Northeast India. Only patients aged 40 years and diagnosed as having acute ischemic cerebrovascular stroke with clinical examination and confirmed by a computed tomography scan were included in the study. Serum calcium levels (total, albumin corrected, and ionized) were collapsed into quartiles, and these quartile versions were used for calculating correlation. Pearson's correlation coefficient was used for comparing calcium levels with IS. Results:: Total calcium, albumin-corrected calcium, and ionized calcium had a statistically significant negative correlation with IS with r = 0.578, 0.5396, and 0.5335, respectively. Total and ionized calcium showed a significant negative correlation with IS across all four quartiles. Albumin-corrected calcium levels showed a significant negative correlation with IS only across the lowest and highest quartiles. Conclusion:: The findings in our study suggest that serum calcium can be used as a prognostic indicator in ischemic stroke as its levels directly correlates with the IS.
