Does left atrial volume affect exercise capacity of heart transplant recipients?

Table 3 Exercise measurements

Variables	N = 50
Baseline heat rate (bpm)	89 ± 14
Baseline systolic blood pressure (mmHg)	125 ± 18
Baseline diastolic blood pressure (mmHg)	78 ± 11
Baseline pressure rate product (bpm·mmHg·10³)	1.09 ± 0.20
Peak exercise heart rate (bpm)	134 ± 18*
Peak exercise systolic blood pressure (mmHg)	161 ± 27*
Peak exercise diastolic blood pressure (mmHg)	81 ± 14
Peak exercise pressure rate product (bpm·mmHg·10³)	2.16 ± 0.49*
Peak respiratory exchange ratio	1.13 ± 0.09
Peak exercise oxygen consumption (ml O_2·min^-1·kg^-1)	17.7 ± 6.0
Peak exercise VE/VCO₂ slope	38.7 ± 7.5

Data are mean ± SD. *P < 0.01 vs. baseline measurements. bpm denotes beat per minute. The comparison of measurements between at baseline and at peak exercise was performed with a paired Student t-test.
