Why the study?

Does surgical revascularization for angina pectoris (diaphragm graft or modified Beck operation) affect lung function at 1 year postoperatively?

Structured PICO

Does surgical revascularization for angina pectoris (diaphragm graft or modified Beck operation) affect lung function at 1 year postoperatively?

Population

42 patients with ischemic heart disease (IHD) undergoing surgical treatment for angina pectoris (25 diaphragm graft, 17 modified Beck operation), compared with 82 controls (11 healthy men, 15 patients with mitral stenosis, 45 subjects with different lung diseases, and 11 patients thoracotomized for diseases not affecting heart or lungs). Total n=124.

Intervention

Diaphragm graft (G) operation or modified Beck (B) operation for angina pectoris

Comparator

Healthy subjects and patients with other conditions (mitral stenosis, lung diseases, non-cardiopulmonary thoracotomy)

Outcome

Changes in lung function (static and dynamic spirometry, nitrogen washout, PaO2, PaCO2) and chest X-ray findings at 1 year postoperativelysurrogate

Surgical revascularization for angina pectoris via diaphragm graft or modified Beck operations leads to significant postoperative reductions in lung function, suggesting these procedures should be avoided in patients with a baseline FEV1 < 2.0 L.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

These procedures were associated with lung function decline; may warrant caution in low-FEV1 patients but leaves open need for randomized confirmation.
