Blood Lactate AUC Is a Sensitive Test for Evaluating the Effect of Exercise Training on Functional Work Capacity in Patients with Chronic Heart Failure

Table 2

Difference from baseline to 12 weeks, all exercise modalities pooled.

	Baseline	12 weeks follow up	P
VO2peak (n = 22) (ml/kg/min)	18.8 ± 4.0	19.6 ± 4.8	0.049
6 MWT (n = 21) (meters)	514 ± 66	545 ± 106	0.035
Lactate AUC(n = 21) (mmL x minutes)	132 ± 60	91 ± 25	0.002

Data are presented as mean ± standard deviation. P- values calculated by paired student-t test for the three different test modalities. VO2_peak: peak oxygen uptake. Lactate AUC: Lactate under the curve. 6 MWT: 6-minute walk test.
