Myocardial Injury After Lung Cancer Surgery: Incidence, Characteristics, Risk Factors, and Prognosis: A Retrospective Cohort Study.
Article in Annals of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to investigate the incidence, characteristics, risk factors, and prognostic implications of myocardial injury after non-cardiac surgery (MINS) in patients with lung cancer undergoing pulmonary resection. MATERIALS AND
methodsWe conducted a retrospective analysis of 1314 consecutive patients with lung cancer undergoing elective pulmonary resection between June and November 2023 at a tertiary cancer referral center. Univariate and multivariate logistic regression analyses were used to identify independent risk factors. Kaplan-Meier survival analysis with log-rank tests were adopted to evaluate the 30 day mortality and major adverse cardiovascular events (MACE). Subgroup analyses according to the extent of lung resection were also conducted.
resultsThe overall incidence of MINS following lung cancer surgery was 10.4%. The majority of cases (92.7%) occurred within the first postoperative day and demonstrated predominantly asymptomatic presentation (78.1%). Independent preoperative risk factors for MINS included male sex, coronary artery disease, creatinine, high-sensitivity cardiac troponin T, thoracotomy, lobectomy, and duration of tachycardia. Although MINS showed no association with 30 day postoperative mortality, it significantly increased the risk of MACE at 30 days in the overall (7.3% vs. 0.2%, p < 0.001), lobectomy (7.0% vs. 0.3%, p < 0.001), and sublobar resection (9.1% vs. 0, p = 0.002) cohorts.
conclusionsMINS is a common postoperative complication following lung cancer surgery, and typically occurs in the early postoperative period. Although it is predominantly asymptomatic, it was significantly associated with increased 30 day MACE.
