PECULIARITIES OF MYOCARDIAL INFARCTION IN SMOKERS
The aim - to determine the peculiarities of myocardial infarction (MI) course in smoking patients. Data on patients with myocardial infarction who were under treatment in the emergency cardiology department (n=681, smokers - 250, nonsmokers - 431) were analyzed. The smokers developed myocardial infarction averagely 12,4 years earlier, than non-smokers. The authors revealed the connection between smoking and posterior and inferior localization of MI. 90 % of smokers developed acute MI, that was largely focal and non-transmural. Smokers received more aggressive treatment of coronary artery thrombosis with systemic thrombolysis and PCI. Smokers received 1 or 2 stents at the PCI in 87,34 % of cases. Coronary atherosclerosis in smokers affects frequently more than 1 artery, it is usually left anterior descending artery or right coronary artery. Smoking contributes to the development of MI at a younger age, despite a less burdensome amnesias for concomitant factors of cardiovascular risk compared to non-smokers. The course of MI in smokers is characterized by a large amount of necrosis and requires more coronary revascularization activities including thrombolytic therapy and stenting.
