MYOCARDIAL INFARCTION AND TOBACCO SMOKING: RISK OF HEART RHYTHM AND CONDUCTION DISORDERS

Smoking increases risk of myocardial infarction and its complications. In
addition, it increases blood pressure, heart rate and vasoconstriction. The purpose of this research was
to determine the relationship between smoking and heart rhythm in patients with myocardial
infarction.
Materials & Methods: This cross sectional study included 40 patients consuming cigarettes, 40
patients bubble and tobacco and 40 non-smoker patients with acute myocardial infarction. The
samples were selected randomly. The occurrence of heart rhythm disorders and heart conduction were
compared. The data were analyzed with statistical methods.
Results: In smokers the prevalence of sinus tachycardia was 12.5%, sinus bradycardia 60%, atrial
fibrillation 17.5%, PVC 45%, RBBB 22.5%, and LBBB 37.5%. In bubble and tobacco using patients
the prevalence of sinus tachycardia 5%, sinus bradycardia 35%, atrial fibrillation 5%, PVC 47.5%,
RBBB 10% and LBBB 42.5% and in nonsmoker patients: sinus tachycardia 5%, sinus bradycardia
45%, atrial fibrillation 7.5%, PVC 20%, RBBB 7.5% and LBBB 32.5%. It was distinguished that there
was a significant relationship between cigarette smoking and heart rhythm disorders (P<0.05) and
there was not a significant relationship between bubble and smoking and heart disrrhythmia and heart
conduction disorders (P>0.05).
Conclusions: Active smoking can lead to heart rhythm disorders and its complications. Further studies
are recommended to compare the form of cardiac rhythm between people who smoke actively and
those exposed to smoke
