Cigarette Control Status Between The CAD Patients And The Susceptible CAD Patients After Interventional Diagnosis Or Therapy

[Objective]To investigate smoking cessation rate and smoking cessation success rate of smokerswith Coronary artery disease (CAD) after Coronary angiography(CAG) or Percutaneouscoronary intervention(PCI),and which of smokers presented with chest pain accompanywith other CAD rish factors after CAG. To compare rate of the two groups, and to discussfactors which inpact the obedience of smoking cessation. To observe the influence to theprocess of smoking cessation after follow-up visit.[Methods]Collecting material of469smokers with first diagnosed Coronary artery disease (CAD)after Coronary angiography(CAG) or Percutaneous coronary intervention (PCI) as theCAD group, and which of266smokers presented with chest pain accompany with otherCAD risk factors after CAG as the susceptible to CAD group(the susceptible group),during December of2010and July of2011, carry out questionnaire survey and smokingcessation suggestion separately. Collecting informations then provide propaganda andeducation during in hospital and before discharging from hospital. Follow up aboutcigeratte control behavio（rquit smoking, in process of smoking cessation, relapse smoking,never quit smoking etc）and risk factors control situation every3months within12monthsafter discharge, then provide assessment and advise to patients. Analyse the ratio changeof different cigarette control behavior separately, smoking cessation rate, and compare thesmoking cessation rate of the two group; To analyse factors that impact the cigarettecontrol status in short-term, interim and long-term. To observe the effect of long-termintervention through providing advice on smoking cessation at every follow-up, promotingmotivation, and to help smokers to achieve goal of quit smoking.[Results] Total470first diagnose CAD smokers, with466follow-ups and24lostfollow-ups(5.1%), among which7deaths (1.5%) and17(3.6%) lost contact or unwilling tocontinue being followed up;266susceptible to CAD smokers,4lost (1.5%) with thereason that lost contact or unwilling to continue being followed up. According to the totalfollow-up time, both group are divided into four subgroups:3-month group,6-monthgroup,9-month group and1-year group.1.The CAD group446patients finish3-month follow-up, ultimately165of which quit smoking (37%),80patients are younger than60years-old(48.5%).243patients fail to quit within the period (54.5%) including relapse or in process of smoking cessation;38patients never quitsmoking.126patients finish1-year follow-up,73of which quit smoking (57.9%),30patientsare younger than60years-old(41.1%), and50failed(39.7%)，3of which never quitsmoking(2.4%).2. The susceptible group262patients finish3-month follow-up, ultimately84of which quit smoking (32.1%),45patients are younger than60years-old(53.6%),111fail to quit within the period (42.4%)including relapse or in process of smoking cessation;67patients never quit smoking.63patients finish1-year follow-up,28of which quit smoking (44.4%), and35failed(55.6%).3.Compare the status and smoking cessation rate between the two groupsIn3months after discharge, the ratio of relapse in CAD group is higher than that ofthe susceptible group significantly, the ratio of trying to quit smoking in susceptible groupis higher than that in CAD group (P<0.01);1year after discharge, the ratio of quitting smoking and the ratio of trying to quitsmoking in CAD group is higher than those in susceptible group;After1year follow-up period the rate of smoking cessation in CAD group is higherthan that in the susceptible group, the rate of relapse in susceptible group is higher thanthat in CAD group, but the difference can’t be proved by statistics (P=0.053).4. In1year follow-up subgroup of CAD group, rate of smoking cessation raise6month after CAG(P=0.000). In1-year follow-up subgroup of apt CAD group, rate ofsmoking cessation raise (P=0.000)..5.Factors influence on rate of smoking cessationBinary logistic regression result according to the CAD group shows, smokingcessation attempt before CAG and quantity of oral drugs may influence rate of smokingcessation3month after CAG. Work situation, tobacco consumption per day, lenth of timesmoking, smoking index, knowledge about negative influence of smoking oncardiovascular system may influence rate of smoking cessation6month after CAG. Statusof other risk factor management or disease recovery may impact in6month after CAG.Binary logistic regression result according to the susceptible group shows that, closecontact with other smokers, work situation, degree of education, age of starting smoking,knowledge about negative influence of smoking on cardiovascular system, advice while discharge, coronary artery lesion, length of time smoking may influence rate of smokingcessation.[Conclusion]The up study provides the rate of smoking cessation in CAD patients and susceptibleCAD patients. The clinical study show that, there are variety of factors impact thesmoking control status and influence the intention of smoking cessation, in role of whichthe smoking control status shifts, and difference is significant between the CAD group andthe apt CAD group. To establish a long-term follow-up relationship, and to provide adviseand help to the patients, is used to change the smoking cessation status and behavior, theultimate rate of smoking cesstion show no statistically significant difference afterlong-term intervention. Consequently, to establish longterm follow-up mechanism,contribute to raise the rate of smoking cessation.
