{"title":"Impact of COPD on cardiovascular risk factors and outcomes in people with established cardiovascular disease","authors":"Eunice Eunae Cho, Laura C Maclagan, Anna Chu, Ruth Croxford, Don D Sin, Jacob A Udell, Douglas Lee, Peter C Austin, Andrea S Gershon","doi":"10.1136/thorax-2023-220991","DOIUrl":"https://doi.org/10.1136/thorax-2023-220991","url":null,"abstract":"Background Little is known about the association between chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) in people with established CVD. Knowing if COPD is associated with a higher risk of cardiovascular events would guide appropriate secondary prevention. Objective To examine the risk of COPD on major adverse cardiac events (MACEs, acute myocardial infarction, stroke and cardiovascular death) in a complete real-world population of a large province, with known CVD. Methods We conducted a retrospective population cohort study using health administration, medication, laboratory, electronic medical record and other data from Ontario, Canada. All people with a history of CVD with and without physician-diagnosed COPD as of 2008 were followed until 2016 and cardiac risk factors, sociodemographic factors, comorbidities and other factors were compared. Sequential cause-specific hazard models adjusting for these factors determined the risk of MACE in people with COPD. Results Of 496 056 individuals with CVD in Ontario on 1 January 2008, 69 161 (13.9%) had COPD. MACE occurred more frequently among those with CVD (45.3 per 1000 person-years) and COPD compared with those with CVD alone (28.6 per 1000 person-years) (HR 1.24, 95% CI 1.21–1.26) after adjustment for cardiac risk factors, comorbidities, socioeconomic status and other factors. People with COPD were less likely to receive preventive CVD medications or see a cardiologist. Conclusion In a large, real-world population of people with established CVD, COPD was associated with a higher rate of cardiovascular events but a lower rate of preventive therapy. Strategies are needed to improve secondary CVD prevention in the COPD population. Data are available upon reasonable request. The dataset from this study is held securely in coded form at ICES.

A clinical diagnosis of congestive heart failure was confirmed after echocardiography showed a left ventricular (LV) ejection fraction of 15%.

Current recommendations assumes two behaviours (adherence and non-adherence) and days 7–90 follow-up post-CPAP initiation mitigates against non-adherence. Objectives To investigate associations between early CPAP-usage behaviours and (1) CPAP adherence at month 3 of treatment and (2) sleep centres’ treatment pathways (the procedures patients undergo that may affect barriers or facilitators of CPAP adherence). Methods We conducted growth mixture modelling (GMM) on retrospective data from 1000 patients at 5 UK sleep centres. Night 1 to month 3 telemonitored CPAP-usage data were downloaded from 200 patients per centre who started CPAP in 2019 (100) or 2020 (100). Adherence was defined using accepted criteria (mean CPAP-usage ≥4 hours/night for ≥70% of nights). Results GMM identified six distinct CPAP-usage behaviour patterns over month 1. In four (54% of patients), CPAP-usage increased or decreased, in two (remaining 46%), CPAP-usage/non-usage was consistent. 62% of the cohort were non-adherent by month 3, despite pathways following current recommendations. 98% of patients who were non-adherent by month 3 were already non-adherent by month 1. Regression analysis with a separate dataset demonstrated that early CPAP-usage behaviour explained 86% of the variance in CPAP non-adherence at month 3. Conclusions These data, supported by previous work, indicate that recommended day 30–90 follow-up is too late to prevent CPAP non-adherence. Determining CPAP-usage behavioural pattern in week 2 identifies risk of CPAP non-adherence at month 3 and permits the possibility of tailored interventions.

An obstructive pattern is defined as an impaired ratio of forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) (ie, FEV1/FVC less than the lower limit of normal (LLN)) (figure 1). It may be caused by asthma and/or chronic obstructive pulmonary disease (COPD) and warrants further testing including bronchodilator responsiveness. Spirometry is essential for diagnosing asthma and COPD, but also for monitoring the course of these highly prevalent chronic airway diseases, including the response to treatment, the level of short-term asthma control and the occurrence of long-term clinical remission. However, there is a second spirometric pattern which is important to discern in clinical practice: preserved ratio impaired spirometry (PRISm), defined as a preserved FEV1/FVC ratio but impaired FEV1 (ie, FEV1 less than 80% predicted). Only recently, PRISm has attracted more attention. Figure 1 The main spirometric patterns encompass an obstructive pattern, a normal spirometry and preserved ratio impaired spirometry (PRISm).
