Effects of intima stiffness and plaque morphology on peak cap stress

Table 3 Percentage changes in the peak cap stress due to alterations in the geometric features for all intima models

Intima stiffness	Cap thickness	Necrotic core thickness	Necrotic core angle	Intima thickness behind necrotic core	Adventitia thickness
	0.25→0.05 mm	0.6→1.4 mm	10°→40°	0.3→0.7 mm	0.1→0.2 mm
Stiff	+200%	+60%	- 6%	-22%	-1%
Intermediate	+205%	+90%	- 7%	-29%	-1%
Soft	+ 55%	+100%	-55%	+27%	-5%

The baseline values of the geometric features were: cap thickness = 0.05 mm, necrotic core thickness = 1.2 mm, necrotic core angle = 30°, intima thickness behind the necrotic core = 0.5 mm, media thickness = 0.25 mm and adventitia thickness = 0.15 mm. The range and direction of the variation are displayed for each feature.
