Evaluation of the relationship between the level of addiction and exhaled carbon monoxide levels with QT dispersion in smokers

Introduction
Smoking increases the risk of arrhythmia. QT dispersion (QTd) is
an important indicator for the determination of ventricular arrhythmia. In this
study, we aimed to determine the arrhythmia risk by evaluating QTd in smokers
and to assess the relationship between the level of nicotine addiction and carbon
monoxide (CO) level in the expiratory air.
Methods
This study was designed as a single-center, cross-sectional study. Among
the chronic smokers referred to the Smoking Cessation Clinic of a tertiary
hospital between October 2019 and January 2020, all those who had no risk
factors for cardiac arrhythmias, except smoking, were included in the study.
Sociodemographic data and smoking characteristics of the participants were
collected and exhaled CO levels were measured. QT intervals were measured in
all leads by using a 12-lead standard electrocardiogram (ECG), and heart rate
corrected QT (QTc) intervals, QT dispersion (QTd), and corrected QT dispersion
(QTcd) were calculated.
Results
The mean age of the 250 patients was 37.2±9.3 years and the majority
of patients (65%) were male. The mean amount of smoking was 25.74±16.03
packs/year and the mean value of CO was 12.36±7.06 ppm. The mean QTd
was 23.83±13.12 ms, and the mean QTcd was 26.63±15.02 ms. A statistically
significant relationship was found between QTd and QTcd and level of addiction,
consumption of sticks/day and packs/year, and exhaled CO values (all p<0.001).
Conclusions
It was found that as the level of addiction, cigarette use amount,
exhaled CO levels, and BMI increased in smokers, QT dispersion and arrhythmia
risk increased. |
