Description of intervention(s) / exposure
Single centre prospective observational longitudinal cohort study with 12 months follow up. Hospitalised patients with acute exacerbations of COPD will be recruited, and undergo CT at baseline and after 12 months. This CT will measure a parameter called pulmonary artery pulsatility (a dynamic CT measurement of pulmonary artery diameter).

Statistical methods / analysis
We aim to recruit 152 patients.

The primary analysis will be a Cox proportional hazards regression. In our preliminary cohort (n=58) HR is about 14.0 (95% 1.6-127) and the prevalence is about 30%. Using Schoenfeld's method (Biometrics 1983) for sample size calculations and inputs alpha 0.05, power 0.8, PH prevalence 30%, a conservative estimate for HR of 2.5 with 10% dropout the number required is 152.

Summary
Brief summary
Many patients with Chronic Obstructive Pulmonary Disease (COPD) also have elevated lung blood pressures, or pulmonary hypertension (PH). Having both conditions increases the risk of death. It is difficult to diagnose PH in COPD. We will be using a new Computed Tomography (X-ray imaging) technique to investigate a marker of PH called ‘pulmonary artery pulsatility’. If PH can be diagnosed easily and accurately new treatments can be devised and researched potentially improving outcomes in COPD.
