Diagnostic Pathology

Table 1 Patient characteristics and S100A1 immunostaining results in 10 human heart samples of group 3

Case	Sex	Age (years)	Duration of symptoms	Postmortem interval (h)	Coronary atherosclerosis (% of narrowing)^☆	loss of S100A1^★

^☆Grade of coronary atherosclerosis: Grade I: 0–25% of narrowing; Grade II: 25–50%; Grade III: 50–75%; Grade IV: >75%.
^★Loss of staining is scaled as: massive loss (++); patchy loss (+); loss in a few disseminated cells (±).
