Key result
Male RCMP cadets exhibit higher myocardial and diastolic performance indices and relaxation times than females.
Why the study?
RCMP cadets experience high volumes of potentially psychologically traumatic events, creating a need for normal cardiac cycle interval data for comparison.
Do baseline cardiac cycle intervals differ between male and female incoming RCMP cadets?
Cross-Sectional
Do baseline cardiac cycle intervals differ between male and female incoming RCMP cadets?
p-value: p=<0.05
Establishing baseline cardiac cycle intervals in RCMP cadets reveals significant sex differences, providing a reference for monitoring occupational cardiac changes.
Sex differences in cardiac indices among cadets may inform sex-specific norms; leaves open whether they affect occupational monitoring or require longitudinal confirmation.
Royal Canadian Mounted Police (RCMP) cadets experience high volumes of potentially psychologically traumatic events, suggesting a need of normal cardiac cycle interval data on the cadets for comparison. We characterize the cardiac cycle of incoming RCMP cadets starting the 26-week training program. The cadets collected their cardiac data using the LLA Recordis™ device. Male RCMP cadets had higher ( p < 0.05) myocardial and diastolic performance indices, aortic valve open to aortic twist time, and isovolumic relaxation time than female RCMP cadets. Monitoring the cardiac cycle intervals in RCMP cadets can provide insights into changes in their heart function from their occupational demands.

Singh et al. (2024) conducted a cross-sectional in Healthy RCMP cadets. Male sex vs. Female sex was evaluated on Myocardial and diastolic performance indices, aortic valve open to aortic twist time, and isovolumic relaxation time (p=<0.05). Male RCMP cadets had higher myocardial and diastolic performance indices, aortic valve open to aortic twist time, and isovolumic relaxation time than female RCMP cadets (p < 0.05).
