Abstract:
Smoking habits represent a cardiovascular risk factor with a tremendous impact on health. Other than damaging differentiated and functional cells of the cardiovascular system, they also negatively affect reparative mechanisms, such as those involved in cardiac fibrosis and in endothelial progenitor cell (EPC) activation. In recent years, alternative smoking devices, dubbed modified tobacco risk products (MRPs), have been introduced, but their precise impact on human health is still under evaluation. Also, they have not been characterized yet about the possible negative effects on cardiovascular reparative and regenerative cells, such as EPCs or pluripotent stem cells. In this perspective, we critically review the still scarce available data on the effects of MRPs on molecular and cellular mechanisms of cardiovascular repair and regeneration.
Insights
Modified tobacco risk products (MRPs) may harm cardiovascular health by impairing cell repair mechanisms. Further research is needed to understand their impact on endothelial progenitor cells and cardiovascular regeneration.
Area of Science:
- Cardiovascular Science
- Regenerative Medicine
- Toxicology
Background:
- Smoking is a major cardiovascular risk factor, damaging cells and impairing repair processes like cardiac fibrosis and endothelial progenitor cell (EPC) activation.
- Modified tobacco risk products (MRPs) are emerging alternatives, but their health effects, particularly on cardiovascular regenerative capacity, remain largely unevaluated.
- Understanding MRPs' impact on cardiovascular repair is crucial given their potential to influence heart health and recovery.
Purpose of the Study:
- To critically review existing data on the effects of MRPs on cardiovascular repair and regeneration at the molecular and cellular levels.
- To assess the potential negative impacts of MRPs on crucial reparative cells, including EPCs and pluripotent stem cells.
- To highlight the current knowledge gaps regarding MRPs' influence on cardiovascular health and recovery mechanisms.
Main Methods:
- Literature review of scarce available data on MRPs and cardiovascular cellular mechanisms.
- Critical analysis of studies investigating MRPs' effects on endothelial progenitor cells (EPCs) and pluripotent stem cells.
- Evaluation of molecular and cellular pathways involved in cardiovascular repair and regeneration affected by MRPs.
Main Results:
- Current data on MRPs' effects on cardiovascular repair and regeneration is limited.
- Potential negative impacts on EPC activation and other reparative mechanisms are suggested but not fully characterized.
- Further research is required to elucidate the specific cellular and molecular consequences of MRP use on cardiovascular health.
Conclusions:
- The impact of modified tobacco risk products (MRPs) on cardiovascular repair and regeneration is not well-understood.
- MRPs may pose risks to cardiovascular regenerative capacity, affecting cells like EPCs.
- More research is urgently needed to characterize these risks and inform public health strategies.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases.
