Relationship Between Cardiorespiratory Fitness, Baseline Blood Pressure and Hypertensive Response to Exercise in the Ferrari Corporate Population

Aim To evaluate the incidence and clinical signifcance of impaired cardiorespiratory ftness (CRF) and the association with baseline blood pressure (BP) levels and hypertensive response to exercise (HRE). Methods A cross-sectional study was conducted on a total sample of 2058 individuals with a mean age of 38 ± 9 years, enrolled for the frst time at the Ferrari corporate wellness program “Formula Benessere”, including a maximal exercise stress testing (EST). BP and heart rate (HR) values were obtained from EST at rest, during exercise and recovery time. CRF was arbitrarily classifed according to estimated VO2 max in optimal, normal, mildly and moderately reduced. Results One-hundred and thirty-nine individuals of 2058 (6.7%) showed a moderate CRF reduction assessed by EST. Subjects with elevated resting and/or exercise BP showed a worse CRF than those with normal BP levels, also after the adjustment for age, sex, body mass index, smoking habits, peak SBP and DBP. Seventy-seven individuals (3.7%) showed an HRE during EST, with normal baseline BP levels. Conclusion About 7% of a corporate population showed a signifcantly reduced CRF, assessed by EST. Individuals with lower levels of CRF have higher resting and/or peak exercising BP values after adjusting for co-variables. This study expands the role of EST outside of traditional ischemic CVD evaluation, towards the assessment of reduced CRF and HRE in the general population, as a possible not evaluated CV risk factor
