Smoking status effects on common carotid arteries peak systolic velocity and end diastolic velocity in current sudanese smokers

This study intended to determine the effects of smoking status (number of cigarettes smoked per day) in common carotid arteries peak systolic velocity (PSV) and end diastolic velocity (EDV), in current Sudanese smokers. A prospective study was performed with a group of 900 healthy adults who categorized after scanning to (26.7% smoked 1-4 Cigarettes/day, 16% smoked 5-9 Cigarettes/day, 53.3% smoked 10-more Cigarettes/day and 4% were non smokers) and aged 18 to 50 years (12 women, 888 men; mean age of all patients, 28±11). In all cases, carotids ultrasound scanning protocol should meet or exceed the standards established by the American Institute of Ultrasound in Medicine (AIUM) to measure PSV and EDV. For the statistical analysis, Microsoft Excel Software and Statistical Package for the Social Sciences (SPSS) were used. Increase cigarettes' consumption per day in current smokers increases the PSV (P value < 0.0001) and it decrease the EDV (P value < 0.0001) which considered to be extremely statistically significant for the right and left common carotid arteries, when compared to values obtained from the non smokers group. Findings indicate that Smoking status in current Sudanese smokers effectively influenced common carotid arteries PSV and EDV with a positive and negative linear correlation manner respectively.
