Impact of Histidine-Tryptophan-Ketoglutarate Cardioplegia on Perioperative Prognosis in Surgery Patients for Combined Valvular and Coronary Heart Disease: A Retrospective Study.
Article in Reviews in cardiovascular medicine, 2025. 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
Background: Combined valve and coronary surgery is technically complex, and the prognosis for such patients remains poor. This study aimed to analyze the short-term prognostic effects of histidine-tryptophan-ketoglutarate (HTK) cardioplegia versus 1:4 cold blood (CB) cardioplegia in patients requiring combined valve and coronary surgery. Methods: This retrospective cohort study categorized patients undergoing valve surgery combined with coronary artery bypass grafting (CABG) into two groups: the HTK group (n = 504) and the CB group (n = 188), based on the type of cardioplegia used. Propensity score matching (PSM) was employed to adjust for baseline differences between the groups. The primary endpoints included operative mortality, postoperative myocardial infarction (PMI), postoperative acute kidney injury (AKI), and postoperative atrial fibrillation (POAF). Secondary endpoints included stroke incidence, ventilation time, aortic cross-clamp time, and intensive care unit (ICU) length of stay (LOS). Results: After PSM, patients with HTK experienced significantly lower rates of AKI and POAF ( Conclusions: HTK cardioplegia reduced postoperative ventilation time, ICU LOS, and the incidence of AKI and POAF compared with CB cardioplegia in patients undergoing valve surgery combined with CABG. HTK cardioplegia is effective, safe, and superior to CB cardioplegia in improving short-term outcomes in these patients.
