Smoking is associated with increased plasma homocysteine levels, and both are associated with an increased risk of cardiovascular disease. However, little information is available on the effects of passive smoking on the level of homocysteine in nonsmokers. We analyzed the data of self-reported never-smokers (aged ≥ 20 years, n = 3,232), who were from the Third National Health and Nutrition Examination Survey. We quantified the passive nicotine exposure by dividing the never-smokers into quartiles as based on the serum cotinine values. Multiple linear and logistic regression models were used to determine any independent relationships between serum cotinine concentration and levels of homocysteine, vitamin B12, and folate. An elevated homocysteine level was defined as a concentration greater than the 80th percentile. A reduced folate or vitamin B12 level was defined as a concentration less than the 20th percentile.After adjusting for age, gender, body mass index, race, folate and vitamin B12 levels, increased cotinine levels (quartile III and IV) were found to be associated with hyperhomocysteinemia. There was a strong nonlinear increase in the serum homocysteine levels across the quartiles of cotinine. Multivariate analysis showed that age, male gender, non-Caucasian, low levels of folate and vitamin B12, and increased serum cotinine (quartile II-IV) were independently associated with elevated homocysteine levels. In conclusion, these findings indicate that passive smoke exposure in never-smokers is positively and independently associated with plasma homocysteine levels in a dose-dependent manner. These findings may help further determine the link between passive smoking and cardiovascular events.

The clinical outcome of patients with acute myocardial infarction (MI) with unprotected left main coronary artery (LMCA) stenosis is not fully understood. We sought to assess the outcomes of patients with acute MI who underwent percutaneous coronary intervention (PCI) for unprotected LMCA stenosis. A total of 587 patients enrolled in the Korea Acute Myocardial Infarction Registry with LMCA stenosis were analyzed. Patients with culprit LMCA had higher inhospital mortality than patients with non-culprit LMCA (16.0% versus 8.9%, P = 0.008), but had similar clinical outcomes during a 12-month follow-up. Compared to CABG, PCI using drug-eluting stents (DES) was more frequently performed with similar early and 12-month clinical outcomes. The efficacy of sirolimus-eluting stents, paclitaxel-eluting stents, and zotarolimus-eluting stents were comparable at 12-month clinical follow-up. Predictors of 12-month mortality included mechanical ventilation, cardiogenic shock, age > 65 years, and ejection fraction < 40%. Patients with acute MI and culprit LMCA have higher early mortality than patients with non-culprit LMCA. PCI with DES is frequently performed and the clinical outcome is similar between the 3 types of first-generation DES.
