Abstract

Objectives: To know the frequency of obstructive pattern on spirometry in asymptomatic chronic smokers. Study Design: Cross-sectional study. Settings: Department of Pulmonology, Sahiwal Medical College Sahiwal. Period: 1st Nov, 2019 to 1st May 2020. Materials & Methods: A total of 205 chronic smokers aged 30-60 years were included. Patients with history of Ischemic heart disease, previously diagnosed cases of COPD and asthma were excluded. Spirometry was done by using portable spirometer by consultant pulmonologist (at least 2 years of post-fellowship experience) and obstructive pattern (COPD) was noted. Results: Majority males with ages between 41 to 50 years( mean age 47.78 ± 4.90 years)  out of the 205 patients, 137 (66.83%) were male and 68 (33.17%) were females with male to female ratio of 2:1. Mean duration of smoking was 8.81 ± 4.67 years. Mean height was 161.81 ± 9.23 cm. Mean weight was 78.81 ± 5.67 kg. Mean BMI was 26.21 ± 5.39 kg/m2. In this study, frequency of obstructive COPD on spirometry in asymptomatic chronic smokers was found in 29 (14.15%) patients. Conclusion: This study established that frequency of obstructive pattern on spirometry in asymptomatic chronic smokers is high.
