Asymptomatic Atherosclerosis in Egyptian Rheumatoid Arthritis Patients and Its Relation to Disease Activity

Table 9

Comparison of endothelial function between group 1A patients and controls.

	Group 1A; ( = 92)	Controls; ( = 40)
	Mean ± SD	Mean ± SD
Pre-FMD (average)	3.7 ± 0.52	3.9 ± 0.49	0.1
Post-FMD (average)	3.43 ± 0.6	5.109 ± 0.52
FMD dilatation %	16.26 ± 7.35	28.52 ± 10.11
Pre-GTN (average)	3.14 ± 0.56	3.91 ± 0.49	0.2
Post-GTN (average)	4.64 ± 0.71	4.89 ± 0.62	0.14
GTN dilatation %	24.33 ± 9.1	25.72 ± 9.67	0.5
Dilatation ratio	0.69 ± 0.25	1.078 ± 0.189

FMD = flow mediated dilatation, GTN = glyceryl trinitrate.
Highly significant.
