Basal body weight and hemodynamic measures for young and aged rats with HF and for young and aged sham HF rats

	YSHAM (n = 16)	YHF (n = 11)	ASHAM (n = 10)	AHF (n = 11)
Body wt, g	368 ± 8	383 ± 9	385 ± 7	389 ± 8
MAP, mmHg	108 ± 4	100 ± 2	85 ± 3†	92 ± 4
HR, beats/min	390 ± 6	347 ± 11*	359 ± 11†	330 ± 9*

Values are means ± SE; n, no. of rats. Y_SHAM and A_SHAM, young and aged rats without heart failure (HF), respectively; Y_HF and A_HF, young and aged rats with HF, respectively; MAP, mean arterial pressure; HR, heart rate. P < 0.05, HF vs. age-matched sham groups (*) and aged vs. young condition-matched groups (†).
