title: [Coronary characteristics of young smokers with coronary heart disease and the effects of tobacco control on smoking cessation].
abstract: OBJECTIVE
  Coronary features of young smokers and non-smokers with coronary heart disease were compared and the effect of tobacco control education was analyzed.
  
  
  METHODS
  A total of 160 young patients (14 - 35 years old) diagnosed with coronary heart disease by coronary angiography were included in this study, patients were followed up for 3 months. There were 118 smokers and 42 non-smokers, smokers were further divided to psychological counseling intervention group (68 cases) and control group (50 cases), non-smokers were also divided into psychological counseling intervention group (22 cases) and control group (20 cases).
  
  
  RESULTS
  Incidence of single-vessel lesion (50.84% vs. 66.67%) was significantly lower, acute coronary syndrome (75.42% vs. 50.00%), double-vessel lesions (24.58% vs. 19.05%), three-vessel lesions (11.86% vs. 4.74%) as well as coronary artery ectasias (12.71% vs. 9.52%) was significantly higher in smokers than in non-smokers. Gensini scores (61.94 ± 40.35 vs. 45.08 ± 28.97) was significantly higher in smokers than in non-smokers (all P < 0.05). At the end 3-months follow up, smoking cessation rate was significantly higher in psychological counseling intervention group than in control group (61.76% vs. 30.00%, P < 0.05). New smokers was zero in psychological counseling intervention group and 1 in control group among previous non-smokers.
  
  
  CONCLUSIONS
  Smoking is linked with severe coronary artery lesion in young patients with coronary heart disease and psychological counseling intervention could significantly increase the short-term successful smoking cessation rate in these patients.
