Table 2. Clotting times after exposure to myocardial matrix.

The prothrombin time (PT) and the activated partial thromboplastin time (APTT) were obtained for human plasma samples after the addition of saline (control), the myocardial matrix at a standard concentration (1:10,000), and the myocardial matrix at a high concentration (1:2,500). Data are means +/− SEM (n = 2).

ECM:plasma	PT (s)	APTT (s)
Control (saline)	11.65 ± 0.071	26.3 ± 0.0
1:10,000	11.75 ± 0.071	25.7 ± 0.141
1:2,500	11.75 ± 0.071	27.5 ± 0.566
