Cigarette smoking and health of the heart
1Medical Division Pontremoli, City Hospital, Castelnuovo Magra (SP), Italy.
Insights
Cigarette smoking, both active and passive, damages the cardiovascular system. Active smoking causes chronic issues like atherosclerosis, while passive smoking acutely impairs heart function, especially in those with existing heart disease.
Area of Science:
- Cardiovascular Science
- Public Health
Background:
- Cigarette smoking is strongly linked to cardiovascular damage.
- Both active and passive smoking negatively impact heart health.
- Cardiovascular diseases represent a significant portion of excess deaths in smokers.
Purpose of the Study:
- To review findings on the relationship between smoking and cardiovascular damage.
- To highlight the specific effects of active versus passive smoking on the heart.
- To present data from an Italian population study.
Main Methods:
- Review of previous research findings.
- Analysis of data from an Italian population.
- Comparison of effects between active and passive smoking.
Main Results:
- Active smoking leads to chronic cardiovascular impairment, primarily coronary atherosclerosis.
- Passive smoking causes transient cardiac performance impairment after acute exposure.
- Passive smoking's effects are more pronounced in individuals with pre-existing ischaemic heart disease.
Conclusions:
- The heart is a target organ for cigarette smoking.
- Smoking cessation is crucial for preventing smoking-related cardiovascular diseases.
- Understanding the differential impacts of active and passive smoking is vital for public health strategies.
Abstract:
A large series of studies relate cigarette smoking to the development of cardiovascular damage. Both active and passive smoking seem to act negatively on the heart, although with different results. Active smoking impairs the cardiovascular system chronically causing mainly coronary atherosclerosis, whereas passive smoking impairs cardiac performance transiently after acute exposure, and to a greater extent in those with established ischaemic heart disease. Evidence indicates that the heart is a target organ for cigarette smoking (Leone, 1992). Diseases of the heart and blood vessels account for over one-third of all the excess deaths in smokers (follow-up report of the Royal College of Physicians, 1983). The purpose of this report is to demonstrate some of the links between cardiovascular damage and smoking by reviewing our previous findings based on an Italian population.
