3.step one. Standard properties
The fresh people throughout the AF classification integrated 21 guys (77.8%) with an indicate age 68.4 ± 8.0 decades ( Desk 1 ). The latest cSR class provided 80 people (75.5%) which have an indicate age 65.dos ± 8.cuatro age. As the clients from the AF category were more mature an average of in contrast to new cSR category, the real difference wasn’t statistically high. Concerning your aerobic history, the newest proportion of patients having ischemic cardiovascular illnesses was filled up with the new cSR class, while the fresh new proportion out-of people which have valvular situation try full of the fresh new AF classification. Calcium supplements channel blockers, renin–angiotensin program blockers, beta blockers, and you will statins was basically recommended so you’re able to people regarding the AF classification just like the better on people about cSR class. not, non-dihydropyridine calcium station blocker, diuretics and you will digoxin were utilized seem to from the AF category ( Dining table step 1 ). Amiodarone is recommended to just one diligent for the cSR group.

Data try displayed while the mean ± SD otherwise number (%) off customers.
The HR at Rest, Wu, AT, Rc, and at Peak were not significantly different between the AF and cSR groups ( Desk 2 and Fig. 2 ). The systolic blood pressure at AT and Peak in the AF group were significantly lower than those in the cSR group. Peak watts in the AF group were lower than that in the cSR group, but the difference was not significant. In terms of VO2/kg, the values of VO2/kg increased during exercise in both groups; however, there was a significantly different trend between AF and cSR. In addition, VO2/kg at Rest, Wu and AT were not significantly different between the AF and cSR groups, whereas VO2/kg at Peak was significantly impaired in the AF group. Similarly, there was a significant difference between the AF and cSR groups in the relative O2 pulse, which is exemplified by VO2 per HR standardized by body weight.

According to the time course of VO2/kg and relative O2 pulse during exercise, the values of VO2/kg were increased during exercise in both groups. In contrast, relative O2 pulse was increased in accordance with the exercise time in the cSR group, whereas relative O2 pulse at Rc and Peak in the AF group had no difference. Therefore, the slope of relative O2 pulse along the increase of exercise was blunted for the AF group compared with that of the cSR group.
Besides CPET parameters, brand new BNP top is somewhat high regarding the AF classification than just throughout the cSR class ( Dining table 2 ). Leftover atrial dimensions (LAD) and RVSP was indeed significantly large regarding AF group compared to the newest cSR group. There had been zero differences in LVEF within AF and cSR communities.
