Laborértékek

• Clinically important pulmonary disease other than COPD, radiological findings, and/or laboratory findings suggestive of a respiratory disease other than COPD that is contributing to the participant's respiratory symptoms.

  • Chest CT scan findings requiring further investigation or repeat CT surveillance before SV14.
• A LVEF < 45% measured by echocardiogram.

Életkor
