Effects of hypertension on cardiac remodeling at four months after surgery

	2K1C	Sham	P
2-month LAD (mm)	5.13±0.51	4.48±0.36	0.099
3-month LAD (mm)	5.63±0.29	4.32±0.41	0.002
4-month LAD (mm)	6.01±0.29	4.78±0.51	0.002
Heart/body weight (%)	0.33±0.07	0.27±0.02	0.132
IVS; d (mm)	1.83±0.09	1.76±0.13	0.589
EF (%)	62.83±4.53	63.98±8.75	0.818
APD90 (ms)	29.53±9.84	43.5±14.24	0.399
ERP (mm)	56±24	38±14	0.499

N=6 for LAD, Heart weight/body weight ratio, (IVS; d) and EF%. N=4 for 2K1C group and N=3 for sham group for APD90, ERP of LA. Data are expressed as mean±SD. APD90 - action potential duration at 90% repolarization; (EF, %) - left ventricular ejection fraction; ERP - effective refractory period; (IVS; d) - interventricular septal thickness; LAD - left atrial diameter
