In this issue of theCanadian Respiratory Journal, Almirall and Bégin (pages 195 to 196) make a suggestion aimed at increasing the use of spirometry by primary care physicians, as well as family and general practitioners. The idea is that spirometry should be performed not necessarily to make specific diagnoses, but to rule in or out the possibility of a number of lung diseases, most notably, chronic obstructive pulmonary disease (COPD). If the patient demonstrates normal forced vital capacity and forced expiratory volume in 1 s, then he or she does not have COPD; if the results are not normal, then COPD is a possibility that can be further investigated.

Abstract Objective: To investigate the clinical characteristics between the frequent exacerbator with chronic bronchitis (FE-CB) phenotype and the non-exacerbator (NE) phenotype among patients with chronic obstructive pulmonary disease (COPD). Methods: We searched CNKI, Wan fang, Chongqing VIP, China Biology Medicine disc, PubMed, Cochrane Library, and EMBASE databases for relevant studies published as of April 30, 2019. All studies that investigated COPD patients with the FE-CB and NE phenotypes and which qualified the inclusion criteria were included. Cross-Sectional/Prevalence Study Quality recommendations were used to measure methodological quality. RevMan5.3 software was used for meta-analysis. Results: Ten case-control studies (n=8848) were included. Compared with the NE phenotype, patients with the FE-CB phenotype showed significantly lower forced vital capacity percent predicted (FVC%pred) [mean difference (MD) -6.69, 95% confidence interval (CI) -7.73–-5.65, P<0.001, I2=5%], forced expiratory volume in one second percent predicted (FEV1%pred) (MD -8.50, 95% CI -11.36–-5.65, P<0.001, I2=91%), and forced expiratory volume in one second/forced vital capacity (FEV1/FVC) (MD -3.76, 95% CI -4.58–-2.95,P<0.001, I2=0%); in contrast, the quantity of cigarettes smoked (pack-years) (MD 3.09, 95% CI 1.60–4.58, P<0.001, I2=41%), COPD assessment test (CAT) score (MD 5.61, 95% CI 4.62–6.60, P<0.001, I2=80%), modified Medical British Research Council (mMRC) score (MD 0.72, 95% CI 0.63–0.82, P<0.001, I2=57%), exacerbations in previous year (2.65, 95% CI 2.32–2.97, P<0.001, I2=91%), body mass index (BMI), obstruction, dyspnea, exacerbations (BODEx) (MD 1.78, 95% CI 1.28–2.28, P<0.001, I2=91%), I2=34%), and Charlson comorbidity index (MD 0.47, 95% CI 0.37–0.58, P<0.001, I2=0] were significantly higher in patients with FE-CB phenotype. No significant between-group difference was observed with respect to BMI (MD-0.14, 95% CI -0.70–0.42, P=0.62, I2=75%). Conclusion: COPD patients with the FE-CB phenotype had poorer pulmonary function and higher CAT score, the quantity of cigarettes smoked (pack-years), frequency of acute exacerbations, and mMRC scores than those with the NE phenotype.

Patients With Heart Failure

Background: Comorbid chronic obstructive pulmonary disease is found in approximately one-third of patients with heart failure. Survival in patients with chronic obstructive pulmonary disease generally decreases as lung function declines. However, the association between lung function, hospitalization and survival is less clear for patients with heart failure. Aim: The purpose of this study was to determine the predictive power of spirometry measures for event-free survival (combined all-cause hospitalization and/or mortality) in patients with heart failure. Methods: In this secondary analysis of data from three prospective, longitudinal studies, we selected patients with a confirmed diagnosis of heart failure who completed airflow limitation assessment using spirometry measures ( n=137): forced vital capacity, forced expiratory volume/second, and forced expiratory volume/second/forced vital capacity. Cox proportional hazards modeling was used to determine the relationship between spirometry and all-cause hospitalization/mortality with and without adjusting for demographic and clinical covariates over a four-year follow-up period. Results: A majority (74%) exhibited some degree of airflow limitation (forced expiratory volume/second<80% predicted value) and 26 (19%) met the spirometric criterion for chronic obstructive pulmonary disease (forced expiratory volume/second/forced vital capacity⩽0.70). Cox proportional hazards regression models compared all-cause hospitalization/mortality between those with and without airflow limitation. Patients with airflow limitation were 2.2 times more likely to be hospitalized or die compared to those without airflow limitations (hazard ratio: 2.20, 95% confidence interval 1.06–4.53, p=0.03). Conclusion: Patients with comorbid heart failure and airflow limitation were at more than double the risk for an event. Spirometric measures may be useful to patients with heart failure, as tailored management of airflow limitation may impact event-free survival.

During coronary angiography in 24 chronic smokers with coronary heart disease, cardiac function measurements were taken and correlated with respiratory function tests. Fourteen patients had evidence of chronic obstructive pulmonary disease. Cardiac output had a direct correlation with vital capacity, forced vital capacity [FVC], forced expiratory volume in 1 s [FEV1], and velocity at 25% of FVC [V [max] 25]. Pulmonary artery resistance was inversely correlated with FEV1/FVC, while pulmonary artery oxygen saturation weakly correlated with FEV1 and V [max] 25. The pulmonary artery pressure had a weak correlation with the pulmonary artery resistance and an intermediate correlation with the right atrium and the right ventricular pressures. Early diagnosis and therapy of chronic obstructive pulmonary disease in smokers may be possible without using invasive methods
