Why the study?
Does switching to an electrically heated cigarette smoking system or no smoking improve prognostic heart rate and rate-pressure-product parameters in adult male smokers?
Does switching to an electrically heated cigarette smoking system or no smoking improve prognostic heart rate and rate-pressure-product parameters in adult male smokers?
Reducing tobacco smoke exposure for 3 days by switching to an electrically heated system or abstaining from smoking improves prognostic heart rate and rate-pressure-product parameters in a dose-dependent manner.

Reducing smoke exposure improves prognostic HR and RPP parameters within days; confirms rapid benefits and extends RCT evidence for harm reduction.
Reduced cigarette smoke exposure in adult smokers switching from a conventional cigarette (CC) to a potential exposure-reduced electrically heated cigarette smoking system (EHCSS) and no smoking (NS) improved exercise performance. The effects of reduced smoke exposure on the prognostic parameters heart rate (HR) and rate-pressure-product (RPP) were investigated. A total of 18 male adult CC-smokers were randomized in a 3-period cross-over study to CC, EHCSS, or to NS for 3 days each before performing spiroergometry. Exposure parameters declined from CC to EHCSS and to NS. Resting HR and RPP increased from NS to EHCSS and to CC. Chronotropic response/HR recovery were more pronounced in NS than in EHCSS and CC. RPPmax was similar in NS and EHCSS and lowest during CC. Reduced tobacco smoke exposure for 3 days improved the prognostic parameters HR and RPP in an apparently dose-dependent manner.
