Table 3 Comparison of MPI results in the three groups.

	Mild AS (n = 27)	Moderate-to-severe AS (n = 15)	Prior AVR/TAVI (n = 5)	P value
SSS ≥ 4	4 (14.8%)	7 (46.7%)	2 (40%)	0.07
LHRs	0.35 ± 0.05	0.37 ± 0.07	0.39 ± 0.06	0.2
LHRr	0.37 ± 0.05	0.38 ± 0.07	0.36 ± 0.08	0.74
Marked RV uptake after stress	0 (0%)	2 (13.3%)	0 (0%)	0.18

Values are presented as mean ± SD or N (%) as appropriate.
SSS, summed stress score; LHRs or r, lung/heart ratio after stress or at rest; RV, right ventricular.
