Abstract

Background: Low forced expiratory volume in 1 s (FEV ₁ ) is a risk factor for asthma exacerbations (AEs). We aimed to determine if asthma control could reduce the future risk of AEs in patients with low FEV ₁ . This study was conducted to evaluate the future risks of AEs within six months according to Asthma Control Test™ (ACT) score and FEV ₁ . Methods: A total of 565 patients with asthma were enrolled from the COREA cohort. The ACT score, lung function test, and number of AEs were assessed at baseline, three-month follow-up, and six-month follow-up with conventional asthma treatments by asthma specialists in real clinical settings. Results: Female sex, low ACT score, low FEV ₁ , low FVC, and AE history in the previous three months were related with increased AEs within six months. AEs during six-month follow-up occurred in 24% of patients with ACT <20 and FEV ₁ < 60% at baseline. Among patients with an ACT score ≥20, 3.4% of patients with an FEV ₁ < 2.16 L and 9.8% of patients with FEV ₁ ≥ 2.16 L had experienced AEs (P = 0.01), although no differences were observed in the presence of AEs within six months according to the predicted FEV ₁ (FEV ₁ ≥ 60% vs. FEV ₁ < 60%, 5.66% vs. 8.51%, P = 0.65). Conclusion: Patient with low FEV ₁ seemed to show higher risk of AEs than those with near-normal FEV ₁ despite ACT score ≥20 and asthma treatments. Therefore, treatment strategies that prevent AEs are needed in high-risk asthmatic patients.
