Background: Although cigarette smoking is a risk factor for cardiovascular disease (CVD), smoking cessation has considerable effects on the reduction of mortality and incidence of acute myocardial infarction (AMI). This study was done to examine the effect of tobacco smoking status and its short-term outcomes after AMI. Materials and Methods: In this longitudinal study, 96 patients smoking tobacco products (cigarette and waterpipe) within the age range of 30-70 years who had undergone angiography following the first AMI were evaluated. The patients were evaluated at three time points in terms of tobacco smoking status, additional myocardial infarction (MI), hospitalization due to cardiac events, and some other variables. Data collection was done using a checklist and phone calls. Results: The mean age of the patients was 52.99±9.2 years. Six months following the first MI, more than 60% of the patients had ceased their tobacco smoking, but over time and at the end of the study, this value diminished, especially in waterpipe smokers. The chance of hospitalization among the men younger than 54 years who were not smokers at the baseline was 0.801. On the other hand, this chance for men below 54 years who smoked 1-10 cigarettes per day was 4.75 times higher (OR=4.747, P=0.002). In addition, men younger than 54 years who smoked waterpipe twice or more per day were hospitalized 31 times more frequently compared to the men who did not smoke waterpipe (P=0.001, OR=31.112). Conclusion: Not smoking cigarettes or waterpipe over time would considerably reduce the chance of hospitalization due to CVD.

“…Intriguingly, several previous studies have reported the results of reduction in the rates of restenosis or target lesion revascularization after interventions (48,49). However, in recent optical coherence tomography-based studies, tobacco use appears to contribute to neointimal hyperplasia and coronary 10.3389/fcvm.2022.918033 artery remodeling following PCI, ultimately to be involved in the recurrent event of coronary revascularization (50,51). As it remains one of the contentious issues, prospective experimental or clinical studies are necessary.…”

BackgroundWhether the effect of smoking on clinical outcomes following an acute myocardial infarction (AMI) is beneficial or detrimental remains inconclusive. We invesetigated the effect of smoking on the clinical outcomes in patients following an AMI.MethodsAmong 13,104 patients between November 2011 and June 2015 from a nationwide Korean AMI registry, a total of 10,193 participants were extracted then classified into two groups according to their smoking habit: (1) smoking group (n = 6,261) and (2) non-smoking group (n = 3,932). The participants who smoked were further subclassified according to their smoking intensity quantified by pack years (PYs): (1) <20 PYs (n = 1,695); (2) 20–40 PYs (n = 3,018); and (3) ≥40 PYs (n = 2,048). Each group was compared to each other according to treatment outcomes. The primary outcome was the incidence of major adverse cardiac and cerebrovascular events (MACCEs), which is a composite of all-cause mortality, non-fatal MI (NFMI), any revascularization, cerebrovascular accident, rehospitalization, and stent thrombosis. Secondary outcomes included the individual components of MACCEs. The Cox proportional hazard regression method was used to evaluate associations between baseline smoking and clinical outcomes following an AMI. Two propensity score weighting methods were performed to adjust for confounders, including propensity score matching and inverse probability of treatment weighting.ResultsWhile the incidence of all clinical outcomes, except for stent thrombosis, was lower in the smoking group than in the non-smoking group in the unadjusted data, the covariates-adjusted data showed statistical attenuation of these differences but a higher all-cause mortality in the smoking group. For smokers, the incidence of MACCEs, all-cause mortality, cardiac and non-cardiac death, and rehospitalization was significantly different between the groups, with the highest rates of MACCE, all-cause mortality, non-cardiac death, and rehospitalization in the group with the highest smoking intensity. These differences were statistically attenuated in the covariates-adjusted data, except for MACCEs, all-cause mortality, and non-cardiac death, which had the highest incidence in the group with ≥40 PYs.ConclusionSmoking had no beneficial effect on the clinical outcomes following an AMI. Moreover, for those who smoked, clinical outcomes tended to deteriorate as smoking intensity increased.

“…Even though, there is some debate, Huang et al [26] demonstrated that persistent smoking increased the size of the neointimal hyperplasia area (1.04 ± 0.72 mm 2 vs 0.96 ± 0.68 mm 2 ; P = .04) and malapposed struts (3.2% vs 1.6%; P = .004) compared with nonsmokers. In addition, persistent smoking for more than 1-year leads to a high incidence of uncovered struts.…”

A comparison of the impact of current smoking on 2-year major clinical outcomes of first- and second-generation drug-eluting stents in acute myocardial infarction

et al. 2019

There are limited studies comparing the effect of current smoking on first-generation (1G)-drug-eluting stents (DES) and second-generation (2G)-DES in acute myocardial infarction (AMI) patients after successful percutaneous coronary intervention (PCI). We investigated the clinical impact of current smoking on 2-year clinical outcomes between the 1G-DES and the 2G-DES in AMI patients after PCI.A total of 11,812 AMI patients with a history of current smoking who underwent successful PCI with 1G-DES (n = 4622) or 2G-DES (n = 7190) were enrolled. The primary endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent AMI (re-MI) or any revascularization (target lesion revascularization [TLR], target vessel revascularization [TVR], and non-TVR). The secondary endpoint was the incidence of definite or probable stent thrombosis (ST).Two propensity score-matched (PSM) groups (3900 pairs, n = 7800, C-statistic = .708) were generated. After PSM analysis, the 2-year cumulative incidence of MACE was significantly higher in the 1G-DES group compared with the 2G-DES (9.4% vs 7.4%, Log-rank P = .002; hazard ratio, 1.281; 95% confidence interval, 1.097–1.495; P = .002) and this increased incidence of MACE was associated with the increased incidence of any revascularization including TLR, TVR, and non-TVR. However, the incidences of ST, all-cause death, re-MI were not significantly different during 2-year follow-up period.2G-DES was the preferred treatment strategy for AMI patients with a history of current smoking to reduce MACE especially, any revascularization rate rather than 1G-DES in this study.
