COPD = chronic obstructive pulmonary disease; LMCA = left main coronary artery disease; LV = left ventricular; PCI = percutaneous coronary intervention; TIA = transient ischemic attack.

  • Parameters included in the Parsonnet classification.

  • Resulting in functional disability, hospitalization, requiring chronic bronchodilator therapy or FEV1 <75% of predicted (10).
