Rise CKMB and Myoglobin Levels in Non-Cardiac Patients of Ischemic Stroke Presenting to Emergency Department of a Tertiary Care Hospital

Abstract

Objective: To assess the rise in CKMB and Myoglobin levels and associated factors in non-cardiac patients of ischemic stroke presenting to the Emergency Department of a Tertiary Care Hospital.

Study Design: Cross-sectional study.

Place and Duration of Study: Department of Emergency Medicine, Pak Emirates Military Hospital (PEMH), Rawalpindi Pakistan, from Dec 2020 to May 2021.

Methodology: A total of 150 patients with ischemic stroke diagnosed by the consultant Emergency physician or medical specialist based on clinical and neuro-radiological findings were included in this study. Serum CKMB and myoglobin levels were assessed along with other baseline investigations among the study participants. In addition, the relationship of age, gender, the severity of the stroke and the presence of non-cardiac comorbidities was assessed with the rise in CKMB and myoglobin levels among the target population.

Results: Out of 200 patients with ischemic stroke included in the study, 114(67.0%) were males, while 86(43.0%) were females. 75(37.5%) patients had either raised CKMB or Myoglobin levels, while 125(62.5%) patients had both biomarkers within range. On the National Institutes of Health Stroke Scale, 110(55.0%) patients had mild, 55(22.5%) had mild to moderately severe, 25(12.5%) had severe, and 10(5.0%) had very severe symptoms. Statistical analysis revealed that increased stroke severity had a statistically significant relationship (p-value<0.001) with raised CKMB/Myoglobin levels in the target population.

Conclusion: Raised CKMB or myoglobin levels were found in many patients with acute ischemic stroke. The stroke severity was associated with raised levels of these biomarkers.
