“…Indeed, in such a population, physiological heat strain may have serious health consequences ( Kenney et al, 2014 ). Despite several epidemiological studies ( Basu and Samet, 2002 ; Gasparrini et al, 2015 ; Amorim et al, 2017 ; Ioannou et al, 2018 ; Tsoutsoubi et al, 2021 ) investigating this issue, the increased cardiovascular morbidity and mortality, particularly in working populations, remains unresolved.…”

IntroductionDuring heatwaves, it is important to monitor workers’ cardiovascular health since 35% of those working in hot environments experience symptoms of heat strain. Wearable technology has been popularized for monitoring heart rate (HR) during recreational activities, but it can also be used to monitor occupational heat strain based on core and skin temperatures and HR. To our knowledge, no devices estimate the cardiovascular strain directly based on stroke volume (SV) or cardiac output (CO). In addition to the hardware, there are limitations regarding the lack of suitable algorithms that would provide such an index based on relevant physiological responses. The validation of the formulae already existing in literature was the principle aim of the present study.MethodsWe monitored the cardiovascular responses of our participants to a supine and 60° head-up tilt at the same time each day. During the test, we measured blood pressure derived by finger photoplethysmography, which also provided beat-by-beat measures of SV and CO. Afterwards, we compared the SV derived from the photoplethysmography with the one calculated with the different equations that already exist in literature.ResultsThe evaluation of the formulae was based on comparing the error of prediction. This residual analysis compared the sum of the squared residuals generated by each formula using the same data set.ConclusionOur findings suggest that estimating SV with existing formulae is feasible, showing a good correlation and a relatively small bias. Thus, simply measuring workers’ blood pressure during breaks could estimate their cardiac strain.

“…For instance, the increase in mortality rate during the summer can be as high as 400% [5]. The association between mortality and ambient temperature is cause-specific, as some studies have reported that both cold and hot ambient temperatures increases mortality rates due to cardiovascular causes [1,[5][6][7][8][9][10]. Furthermore, the relationship between ambient temperature and all-cause mortality rate is not the same in all age groups; the daily number of heat-related deaths is more prevalent among elderly individuals [6,11].…”
