Pneumonia After Heart Surgery: Can AI Predict It?

Official title: Hospital-acquired Pneumonia After Cardiovascular Surgery (CS): the Prediction and Assessment of Long-term Cardiovascular and Pulmonary Outcomes With Artificial Intelligence (AI) - (PNEUMONIA-CS-AI)

Run by Tomsk National Research Medical Center of the Russian Academy of Sciences · NCT07745491 · Data updated 2026-11-12

This study tests whether artificial intelligence can predict hospital-acquired pneumonia after heart surgery and whether pneumonia can indicate higher risk of future heart and lung problems.

Is this trial a fit for you?

Likely a good fit

Adults (18+) undergoing current hospitalization for cardiac or vascular surgery who consent to anonymized data use.

Probably not a fit

Patients who do not develop pneumonia or who do not experience the composite outcomes may see no direct benefit from the predictive tools.

What this trial studies

This multicenter, prospective observational study will collect data from adults undergoing cardiac or vascular surgery to develop personalized AI-based risk calculators for post-surgical pneumonia and for a 1-year composite cardiovascular and pulmonary outcome. It will apply machine learning methods to identify risk factors and predict pneumonia development, aiming to support clinical decision-making with individualized risk estimates. No experimental treatments will be used; data analysis will be performed on anonymized patient records in accordance with approved medical care standards. The study involves three centers in Tomsk, Russia, and does not include interventional protocols beyond standard care.

Why it matters

Potential benefit: If successful, clinicians could tailor preventive strategies and post-operative care based on individual risk, potentially reducing pneumonia rates and improving long-term cardiovascular and pulmonary outcomes.

How similar studies have gone: Prior research in AI-based prediction for post-surgical complications has shown promise in some settings, but this specific pneumonia-after-cardiac-surgery and 1-year composite outcomes approach is not yet established.
