Preventing Adverse Cardiac Events in COPD

January 15, 2024 updated by: The George Institute

Preventing Adverse Cardiac Events in Chronic Obstructive Pulmonary Disease

A double-blind, randomised controlled trial in participants with COPD to assess the efficacy of proactive treatment of cardiac risk in people with COPD. We hypothesise that treating known and undiagnosed CVD in COPD participants will improve both cardiac and respiratory outcomes.

Study Overview

Detailed Description

Chronic Obstructive Pulmonary Disease (COPD) is the third leading cause of global health-related morbidity and mortality. Heart disease in COPD is a known but neglected comorbidity and cardiovascular disease (CVD) accounts for 30-50% of deaths in COPD participants. Studies repeatedly show that CVD in COPD participants is under-recognised and under-treated yet participants with COPD are frequently excluded from clinical trials of drugs which reduce cardiac morbidity and mortality. This has led to under-treatment of CVD in COPD participants. A particular concern is low use of β-blockers. These have previously been considered to be contra-indicated in COPD and no RCTs have been conducted in this population. There is now observational evidence that cardioselective β-blockers are safe and may improve mortality, but this data is limited to retrospective analyses of cohorts of COPD participants. Contrary to previous concerns, retrospective analyses also suggest that cardioselective β-blockers may reduce the risk of COPD exacerbations. The proposed study will focus on treating CVD in COPD participants to reduce mortality and morbidity.

The study will be conducted in approximately 20 sites in Australia and New Zealand, and possibly 1-2 international sites. Participants with COPD will be randomised to one of two treatment arms in addition to receiving usual care for their COPD over the study duration of 24 months.

  3. Unstable left HF (i.e. symptomatic and/or necessary change in management in the last 12 weeks, or in clinicians' opinion)

  6. 2nd or 3rd degree heart block
  7. Currently using or have been prescribed LTOT or resting saturated oxygen level <90% when stable
  8. Expected survival is less than 12 months, or in the investigator's opinion, the person has such unstable disease (of any type) that maintaining 12 months' participation would be unlikely
  9. Clinical instability since a MACE in the previous 12 weeks
  10. Lower respiratory tract infection or AECOPD within the last 8 weeks
  11. COPD not clinically stable as determined by the investigator
  12. In the clinician's view, have asthma-COPD overlap or co-existent asthma are present; or an improvement in FEV1 ≥400mL post-bronchodilator is observed on two occasions
  13. Females of child-bearing age and capability who are pregnant or breastfeeding or those in this group not using adequate birth control
  14. Coexistent illness which precludes participation in the study (poorly controlled diabetes, active malignancy)
  15. Severe end-stage liver disease defined by INR>1.3 and albumin<30g/L or portal hypertension/ascites
  16. High chance in the view of the treating physician that the potential participant will not adhere to study requirements

Quality of life assessed by St George's Respiratory Questionnaire (SGRQ)
Time Frame: Baseline to 24 months

The SGRQ is a 50-item questionnaire developed to measure health status (quality of life) in patients with diseases of airways obstruction.

Scores are calculated for three domains:

Symptoms, Activity and Impacts (Psycho-social) as well as a total score.

Psychometric testing has demonstrated its repeatability, reliability and validity. Sensitivity has been demonstrated in clinical trials.

A minimum change in score of 4 units was established as clinically relevant after patient and clinician testing. The SGRQ has been used in a range of disease groups including asthma, chronic obstructive pulmonary disease (COPD) and bronchiectasis, and in a range of settings such as randomised controlled therapy trials and population surveys.

Baseline to 24 months
EuroQoL Group 5-5 Dimension self-report questionnaire (EQ-5D-5L) to assess health state utilities
Time Frame: Baseline to 24 months

EQ-5D-5L consists of 2pg: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).

Five dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression.

Each dimension 5 levels: no problems, slight problems, moderate problems, severe problems, extreme problems.

Patient indicates their health state by ticking most appropriate statement in each of the five dimensions.

This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.

EQ VAS records patient's self-rated health on a vertical visual analogue scale. Endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement.

Baseline to 24 months
Healthcare utilisation costs and Quality Adjusted Life Years (QALYs) evaluation of the treatment intervention
Time Frame: Baseline to 24 months

Mean differences in healthcare utilisation costs and Quality Adjusted Life Years between both treatment groups will be estimated.

Costs will be ascertained from participants and study records. Health care utilisation will be on the basis of self-reported GP and hospital attendances and changes in concomitant medication. Health state utilities will be estimated via the EQ-5D-5L and will be used to weight survival up to 24 months to determine Quality Adjusted Life Years.
