Comparative Analysis of Concurrent and Staged Surgical Treatment for Lung Cancer Complicated With Coronary Heart Disease and Its Effect on Prognosis

Objective: To investigate the effect of different surgical methods on the prognosis of 84 patients with lung cancer complicated with coronary heart disease. Methods: Data of patients with lung cancer complicated with coronary heart disease who received surgical treatment in our hospital from January 2018 to November 2024 were collected. The patients were divided into OPCAB 1 simultaneous operation group, PCI 2 postoperative operation group, and non‐revascularization operation group according to the surgical method, and then, the PCI postoperative operation group was divided into two groups according to the two surgical intervals. Clinical data such as the evaluation of surgical safety and the effect of the time of operation after PCI on the prognosis of patients with lung cancer were used to guide the treatment of these patients. Results: The probability of coronary artery complications is higher in patients undergoing pulmonary surgery with PCI indications and no treatment for coronary artery disease. There was no significant difference in the probability of coronary artery complications in lung cancer patients who underwent surgery within 2 months after PCI versus those who underwent surgery within 2–4 months after PCI. However, the time window of surgery after PCI has an impact on the prognosis of patients with lung cancer. Conclusion: There was no significant difference in the duration of intraoperative bleeding, drainage tube removal, and hospital stay between patients undergoing pulmonary surgery after PCI and those without coronary revascularization. Pulmonary surgery after PCI was safe and feasible, and pulmonary surgery within 2 months after PCI was safe and feasible, and the prognosis of patients undergoing pulmonary surgery after PCI was different in different time windows. Pulmonary surgery should be performed as early as possible within the 2‐month time window after PCI. Patients undergoing pulmonary surgery with PCI indications and without prior treatment of coronary artery lesions have a higher probability of postoperative coronary complications. Therefore, lung cancer surgery as soon as possible after PCI can be considered to have a good impact on the prognosis of patients.
