Cigarette smoking and chest pain.

Area of Science:

• Cardiology
• Public Health
• Epidemiology

Background:

• Cigarette smoking is a major risk factor for cardiovascular disease.
• Chest pain is a common symptom with diverse etiologies.
• The relationship between smoking and various types of chest pain requires further elucidation.

Purpose of the Study:

• To investigate the association between cigarette smoking and the prevalence of nine distinct types of chest pain.
• To explore potential confounding factors and mediating mechanisms in the smoking-chest pain relationship.

Main Methods:

• Analysis of questionnaire data from 70,208 individuals undergoing multiphasic health checkups.
• Comparison of chest pain prevalence between smokers and nonsmokers, stratified by demographics and other health complaints.
• Statistical assessment to rule out alternative explanations for the observed association.

Main Results:

• Smokers reported a significantly higher proportion of chest pain compared to nonsmokers (1.6-fold excess in white men, 1.3-fold in white women).
• The excess chest pain in smokers was more pronounced in younger age groups and affected both anginalike and nonanginalike pain.
• The association persisted after accounting for alcohol/coffee consumption, pain tolerance, reliability, cough, shortness of breath, coronary disease, and musculoskeletal complaints.

Conclusions:

• Cigarette smoking is independently associated with an increased reporting of chest pain across multiple types.
• The findings challenge the broad application of the "tobacco angina" concept, advocating for individualized assessment.
• Further research may be needed to understand the specific mechanisms linking smoking to chest pain in the absence of established coronary heart disease.
