- Laboratory results for patients younger and older than 45 years. A) Mean white blood cell count (WBC) among patients younger than 45 years of age in comparison to that among patients aged 45 years or older at presentation. B-C) Mean neutrophil and lymphocytic count in patients younger and older than 45 years at presentation B) Mean hemoglobin (Hgb) level among patients younger than 45 years in comparison to that among patients aged 45 years or older. E) Mean creatinine level in patients younger than 45 years in comparison to that among patients aged 45 years or older. F-H) The cardiac markers creatine kinase (CK), creatine kinase-MB (CK-MB), and troponin among patients younger than 45 years in comparison to that among patients aged 45 years or older. *p<0.05, **p<0.01, and error bars represent the 95% confidence interval.
