“…Previous report has shown that the maximal age-predicted HR depends on optimization of b-blocker dosing in HF patient [2,25]. In our study, the HR in maximal effort evaluation was 93.8 ± 4.9% of the predicted in the whole sample, estimated by the specific equation to predict HR max in patients receiving this therapy [18].…”

“…This neurohormonal axis has become one of the biggest targets in heart failure interventions 10,11,12,13,14,15. It is well known that beta-blockers provide survival improvement and, because of this, have become one of the main drugs for treating heart failure 16…”

OBJECTIVE:We sought to evaluate the neurohormonal activity in heart transplant recipients and compare it with that in heart failure patients and healthy subjects during rest and just after a 6-minute walking test.INTRODUCTION:Despite the improvements in quality of life and survival provided by heart transplantation, the neurohormonal profile is poorly described.METHODS:Twenty heart transplantation (18 men, 49±11 years and 8.5±3.3 years after transplantation), 11 heart failure (8 men, 43±10 years), and 7 healthy subjects (5 men 39±8 years) were included in this study. Blood samples were collected immediately before and during the last minute of the exercise.RESULTS:During rest, patients’ norepinephrine plasma level (659±225 pg/mL) was higher in heart transplant recipients (463±167 pg/mL) and heathy subjects (512±132), p<0.05. Heart transplant recipient’s norepinephrine plasma level was not different than that of healthy subjects. Just after the 6-minute walking test, the heart transplant recipient’s norepinephrine plasma level (1248±692 pg/mL) was not different from that of heart failure patients (1174±653 pg/mL). Both these groups had a higher level than healthy subjects had (545±95 pg/mL), p<0.05.CONCLUSION:Neurohormonal activity remains increased after the 6-minute walking test after heart transplantation.

“…Heart rate is a cardiovascular variable easily and cheaply measured by a simple heart rate monitor [9]. The advantage of using the heart rate as a variable to monitor and prescribe the exercise training is the close relation with VO 2 in both healthy people and in heart failure patients [10].…”

“…The %VO 2 R was calculated as %VO 2 R = submaximalVO 2 − restVO 2 ÷VO 2 reserve × 100. Resting and peak effort values of both %VO 2 R and %HRR were by definition 0 and 100, respectively [9].…”
