AbstractBackgroundLung cancer survivors are at increased risk for autonomic dysfunction. We aimed to identify determinants of parasympathetic nervous system (PNS) function as reflected by heart rate recovery (HRR) and heart rate variability (HRV) in lung cancer survivors eligible for long-term cure.MethodsWe performed a cross-sectional study of consecutive lung cancer survivors who completed curative-intent therapy for stage I-IIIA ≥1 month previously. We tested a comprehensive list of variables related to baseline demographics, comorbidities, lung cancer characteristics, and physiological/functional measures using univariable and multivariable (MVA) linear regression analyses. We defined HRR as the difference in heart rate (HR) at 1-minute following and the end of the six-minute walk test (6MWT), and HRV the standard deviation of normal-to-normal R-R intervals (SDNN) and root-mean-square-of-successive-differences (rMSSD) from routine single 10-s electrocardiographs (ECGs).ResultsIn 69 participants, the mean (standard deviation, SD) HRR was -10.6 (6.7) beats. In MVAs, significant independent determinants of HRR [β (95% confidence interval)] were: age [0.17 (0.04, 0,30) for each year] and HR change associated with the 6MWT [0.01 (0.007, 0.02) for each beats/min. In 41 participants who had ECGs available for HRV measurements, the mean (SD) SDNN and rMSSD were 19.1 (15.6) and rMSSD 18.2 (14.6) ms, respectively. In MVAs, significant determinants of HRV were: total lung capacity [0.01 (0.00, 0.02), p=0.047 for each % predicted] and HRR [-0.04 (-0.07, -0.003) for each beat] for natural logarithm (Ln-)SDNN; and [0.01 (0.00, 0.02)] and [-0.04 (-0.07, -0.01)] for Ln-rMSSD, respectively.ConclusionsWe measured determinants of HRR and HRV in lung cancer survivors eligible for long-term cure. HRR and/or HRV may be useful as indicators to stratify patients in interventional studies aimed at improving PNS function in lung cancer survivors, including through exercise training.

Concussion History

Context Concussion may negatively influence cardiovascular function and the autonomic nervous system, defined by alteration in heart rate variability (HRV). Differences in HRV most commonly emerge during a physical challenge, such as the final steps of the return-to-sport progression. Objective To assess the effect of concussion history on aspects of cardio-autonomic function during recovery from a bout of submaximal exercise in adolescent male hockey athletes. Design Case-control study. Setting Research laboratory. Patients or Other Participants Thirty-three male athletes participating in Midget-AAA hockey were divided into those with (n = 15; age = 16 ± 1 years, height = 1.78 ± 0.06 m, mass = 73.9 ± 7.4 kg, 10.5 ± 1.6 years of sport experience, 25.2 ± 18.3 months since last injury) or without (n = 18; age = 16 ± 1 years, height = 1.78 ± 0.05 m, mass = 74.8 ± 7.6 kg, 10.6 ± 1.9 years of sport experience) a concussion history. Those with a concussion history were binned on total count: concussion) or 2 or more concussions. Intervention(s) All athletes underwent 5 minutes of resting HRV assessment, followed by 20 minutes of aerobic exercise at 60% to 70% of their maximal target heart rate and a 9-minute, postexercise HRV assessment. Main Outcome Measure(s) Heart rate variability measures of mean NN interval, root mean square of successive differences, and standard deviation of NN interval (SDNN). Results Group demographic characteristics were not different. When the control and concussed groups were compared, group and time main effects for heart rate recovery, root mean square of successive differences, and SDNN (P values < .01), and an interaction effect for SDNN (P < .05) were demonstrated. Recovery trends for each group indicated that a history of 2 or more concussions may negatively affect cardio-autonomic recovery postexercise. Conclusions Our findings suggest that those with more than 1 previous concussion may be associated with a greater risk for long-term dysautonomia. Future use of HRV may provide clinicians with objective guidelines for concussion-management and safe return-to-participation protocols.
