Impact of cancer history on coronary calcification and clinical outcomes in intravascular ultrasound-guided percutaneous coronary intervention.

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
backgroundCancer survivors have an elevated cardiovascular disease burden, yet the influence of cancer history on coronary calcification and outcomes following percutaneous coronary intervention (PCI) is not well characterized. This study investigated the association between cancer history and coronary calcification assessed by intravascular ultrasound (IVUS), and examined outcomes after IVUS-guided PCI.
methodsWe retrospectively evaluated 450 patients with stable angina who underwent IVUS-guided PCI between January 2020 and March 2024 and stratified them into cancer ( n = 110) and non-cancer ( n = 340) groups. Coronary calcification was graded using an IVUS-derived calcium score. Major adverse cardiac and cerebrovascular events (MACCEs) were assessed during follow-up. Multivariate logistic and Cox regression analyses identified predictors of severe calcification (IVUS-calcium score ≥2) and MACCEs excluding cancer-related deaths. Furthermore, outcomes of rotational atherectomy for severely calcified lesions were examined.
resultsPatients with a history of cancer had a high prevalence of moderate-to-severe calcification. Cancer history was independently associated with severe calcification (adjusted odds ratio: 2.32; 95% confidence interval: 1.43-3.77; P < 0.001), but not with MACCEs excluding cancer-related deaths. An IVUS-calcium score ≥2 and impaired renal function were independently associated with MACCEs excluding cancer-related deaths. Among patients undergoing rotational atherectomy, clinical outcomes including MACCEs and target lesion revascularization were comparable between groups.
conclusionCancer history was associated with a greater coronary calcification burden; however, clinical outcomes following IVUS-guided PCI showed no significant difference between patients with and without cancer. These findings suggest that appropriate IVUS-guided lesion assessment enable safe revascularization in this high-risk population.
