Expression of uPA, tPA, and PAI-1 in Calcified Aortic Valves

Table 1

Characteristics of patients (pts) and calcium content of the valves with AS. Calcium content of the valves was evaluated using biphotonic absorptiometry; results are expressed as mean ± SD.

	Total no.	Female	Male
Number of pts	65	22	43
Mean age (years)	75	80	72
Calcium content (g/g wet weight)	0.21±0.13	0.16±0.12	0.24±0.12
