“…Differences in myocardial contractility can occur in the absence of detectable changes in left ventricular volumes or function (Hopp et al., ). Global longitudinal strain has been shown to be the most sensitive marker for detecting an increased contractile state (Merchant, Reichek, Kadiyala, Gliganic, & Young, ), which is in line with the current results where PSLS showed the highest increase of all strain parameters following 24‐hr shift and partial sleep deprivation. PSCS was also significantly increased following partial sleep deprivation, while the strain rate parameters (PSCSR and PDCSR) showed no significant increase.…”

Fatigue and sleep deprivation are common phenomena, especially among medical professionals and shift workers. Studies have proven that short episodes of sleep deprivation can lead to sympathetic hyperactivity with an elevation in blood pressure, heart rate, and an increased secretion of stress hormones (e.g. cortisol, noradrenaline, thyroid hormones). In this study investigating cardiac strain in 20 healthy subjects undergoing short-term sleep deprivation, it could be shown for the first time that 24-hr-shift-related short-term sleep deprivation leads to a significant increase in cardiac contractility, blood pressure, heart rate and stress hormone secretion. These findings may help better understand how workload and shift duration affect public health, and lay the foundation for further investigations.
