[A 5-year follow up study on smoking and current smoking cessation status in patients with acute myocardial infarction from a hospital in Xicheng district, Beijing].

OBJECTIVE

To explore the smoking and smoking cessation status in patients with acute myocardial infarction.

METHODS

456 hospitalized patients with acute myocardial infarction in Xicheng district were recorded in CCU ward between October 2003 and October 2008. Personal data and smoking status were collected. The smoking cessation status after discharge was investigated by telephone.

RESULTS

(1) Patients who smoked were still male-dominated (96.3%). The average smoking rate in male patients was 55.9%, and even as high as 87.5% in patients at 29 - 50 years of age. (2) The average age in patients who smoked and with acute myocardial infarction was 58.0 ± 12.3 years old, 16 years advanced the age compared to the groups who never smoked or after stopped smoking. (3) The successful smoking cessation rate in patients with acute myocardial infarction after discharge was 42.5%, and 29 - 50 years old group having the highest rate of successful cessation, while the lowest rate seen in 51 - 65 years old group. (4) The failure rate of smoking cessation was 40.9% with the main reasons as: radical habit on smoking, withdrawal symptoms, stress in work and peer influence etc. The 51 - 65 year-old group was mainly suffered from habitual factors and withdrawal symptoms.

CONCLUSION

The smoking rate and smoking cessation failure rate in adult patients with acute myocardial infarction in Xicheng district in Beijing remained high. The onset age of acute myocardial infarction was significantly in advance among patients who smoked. To actively advocate on smoking cessation was still vital for reducing the occurrence of acute myocardial infarction and to improve the prognosis in patients with myocardial infarction.
