Abstract :

Background: Acute coronary syndrome (ACS) is a major health problem and represents a large number of hospitalizations annually. Myosin light chain (MLC2) is a sensitive early marker (within four hours) of ACS that can be used to confirm or exclude a diagnosis of acute cardiac condition. The present study was undertaken for rapid diagnosis ACS with the help of elevated MLC–2 and its relation with troponin I and ventricular ejection fraction. Method: In this cross sectional study, 60 patients of ACS were enrolled from coronary care unit (CCU), Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) as case and 25 apparently healthy people from cardiac point of view also from BIRDEM as control. Selection of patients was done according to the inclusion and exclusion criteria. MLC–2was measured (within 3–4 hours) by ELISA method and level of ventricular dysfunction and troponin I (in ACS group) was taken from hospital records. Results: The mean ± SEM of MLC–2 was higher in the ACS group (88.02±18.0 pgm/ml) compared to the healthy control group (41.4±2.2 pgm/ml) and difference was statistically significant (p<0.05). The inverse correlation between MCL–2 and ejection fraction was highly significant (r=–0.647, p=0.001). The correlation with MLC–2 and troponin I was also significant (r=0.831, p=0.01). Conclusion: Statistically significant MLC2 level was found in the ACS group than the healthy control group. Positive correlation was also observed between MLC–2 with troponin I and ventricular dysfunction. Therefore, MLC 2 may be used as a biomarker for early diagnosis of ACS with troponin I and ejection fraction.
