Factors associated with coronary heart disease in COPD patients and controls.

ABSTRACT:

Background

COPD and coronary heart disease (CHD) frequently co-occur, yet which COPD phenotypes are most prone to CHD is poorly understood. The aim of this study was to see whether COPD patients did have a true higher risk for CHD than subjects without COPD, and to examine a range of potential factors associated with CHD in COPD patients and controls.

Methods

347 COPD patients and 428 non-COPD controls, were invited for coronary computed tomography angiography (CCTA) and pulmonary CT. Arterial blood gas, bioelectrical impedance and lung function was measured, and a detailed medical history taken. The CCTA was evaluated for significant coronary stenosis and calcium score (CaSc), and emphysema defined as >10% of total area <-950 Hounsfield units.

Results

12.6% of the COPD patients and 5.7% of the controls had coronary stenosis (p<0.01), whereas 55.9% of the COPD patients had a CaSc>100 compared to 31.6% of the controls (p<0.01). In a multivariable model adjusting for sex, age, body composition, pack-years, CRP, cholesterol/blood pressure lowering medication use and diabetes mellitus, the OR (95% CI) for having significant stenosis was 1.80 (0.86-3.78) in COPD patients compared with controls. In a similar model, the OR (95% CI) for having CaSc>100 was 1.68 (1.12-2.53) in COPD patients compared with controls. Examining the risk of significant stenosis and CaSc>100 among COPD patients, no variable was associated with significant stenosis, whereas male sex [OR 2.85 (1.56-5.21)], age [OR 3.74 (2.42-5.77)], statin use [OR 2.23 (1.23-4.50)] were associated with CaSc>100, after adjusting for body composition, pack-years, C-reactive protein, use of angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), diabetes, emphysema score, GOLD category, exacerbation frequency, eosinophilia, and hypoxemia.

Conclusion

COPD patients were more likely to have CHD, but neither emphysema score, lung function, exacerbation frequency, nor hypoxemia predicted presence of either coronary stenosis or CaSc>100.

Project description:BackgroundStudies suggest that up to 70% of chronic obstructive pulmonary disease (COPD) cases globally are undiagnosed worldwide. Some of these undiagnosed patients may present with severe exacerbation and factors associated with underdiagnosis in this population are unknown. We investigated the key factors associated with underdiagnosis in two cohorts of patients hospitalised for severe COPD exacerbation at different time points.MethodsThis retrospective, multicentre study analysed data from patients hospitalised for COPD exacerbation at two independent centres during two distinct time periods: between 1 January 2017 and 31 December 2018 in the Aquitaine region and between 1 January and 31 December 2022 in Paris. Undiagnosed COPD was defined as the absence of pulmonary function testing before the index exacerbation. Multivariate logistic regression was used to evaluate associations between underdiagnosis and patient characteristics.ResultsAmong the 424 patients, 93 (21.9%) were undiagnosed before hospitalisation, with a stable rate over time (22% in 2017-2018 and 21% in 2022). Multivariate analysis revealed that underdiagnosis was related to higher forced expiratory volume in one second (FEV1; adjusted OR (aOR)=1.02, p=0.043) and female sex (aOR=1.91, p=0.015). Patients with undiagnosed COPD had significantly lower rehospitalisation and mortality rates. After the initial severe exacerbation, higher mortality was associated with a higher Charlson Comorbidity Index (HR=1.24, p=0.007) and older age (HR=1.05, p=0.008).ConclusionThis retrospective, multicentre study demonstrated that about 20% of patients admitted with severe exacerbation were undiagnosed for COPD. Higher FEV1 and female sex were associated with underdiagnosis, emphasising the need for special attention to this population. These findings highlight the need to improve training and access to spirometry and develop new diagnostic tools that facilitate earlier detection and management of COPD.

Project description:BackgroundPrimary care for chronic illness varies across European healthcare systems. In patients suffering from coronary heart disease (CHD), factors associated with patients' experiences of receiving structured chronic care and counselling at the patient and practice level were investigated.MethodsIn an observational study comprising 140 general practices from five European countries (Austria, Germany, the Netherlands, Switzerland and the United Kingdom), 30 patients with Coronary Heart Disease (CHD) per practice were chosen at random to partake in this research. Patients were provided with a questionnaire and the Patient Assessment of Chronic Illness Care (PACIC-5A) - instrument. Practice characteristics were assessed through a practice questionnaire and face to face interviews. Data were aggregated to obtain two practice scores representing quality management and CHD care, respectively. A hierarchical multilevel analysis was performed to examine the impact of patient and practice characteristics on PACIC scores.ResultsThe final sample included 1745 CHD-patients from 131 general practices with a mean age of 67.8 (SD 9.9) years. The overall PACIC score was 2.84 (95%CI: 2.79; 2.89) and the 5A score reflecting structured lifestyle counselling was 2.75 (95% CI: 2.69; 2.79). At the patient level, male gender, more frequent practice contact and fewer related or unrelated conditions were associated with higher PACIC scores. At the practice level, performance scores reflecting quality management (p = 0.013) and CHD care (p = 0.009) were associated with improved assessment of the structured chronic care and counselling received.ConclusionsPatients' perceived quality of care varies. However, good practice management and organisation of care were positively reflected in patients' assessments of receiving structured chronic illness care. This highlights the importance of integrating patient experiences into quality measurements to provide feedback to health care professionals.
