Multidisciplinary Insights into Perioperative Cardiac Events in Non-Cardiac Surgery: an ECG Holter Monitoring Study.
Article in Maedica, 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: Cardiovascular complications after non-cardiac surgery have a major impact on perioperative morbidity and mortality. Despite several scales and scores for assessing the preoperative cardiovascular status, an individualized assessment focused on each patient is mandatory. Aim: To identify the new cardiac events that occur after non-cardiac surgery. Methods: In 100 patients hospitalized in the general surgery department with acute and chronic surgical pathologies, the perioperative cardiac events were assessed using Holter monitoring along with clinical and biochemical markers, including C reactive protein (CRP) and high-sensitive troponin (hscTnI). Results: Out of the 100 participants with a mean age of 54.5 (43-77.9) years, 54% were men. Ten patients developed paroxysmal postoperative atrial fibrillation (AF), which was related with longer surgery time 165 (150-180) vs 120 (90-150) minutes (p=0.002) and postoperative anaemia [haemoglobin (Hg) 10.4 (9.37-12.6) vs 12.1 (11-13.2) g/dL, (p=0.041)]. Higher CRP levels were also correlated with paroxysmal AF. The AF group correlated with higher values of presurgical CRP: 81 (46.5-186.75) vs 27 (6-102.5) mg/dL, (p=0.041). Higher postsurgical CRP values were also found in the AF group: 76 (47.75-110.75) vs 40.5 (12-82.5) mg/dL (p=0.045). Sinus pauses were present in nine patients and there was a strong association between sinus pauses and age (p = 0.011), history of high blood pressure (HBP) (p = 0.031), intraoperative HBP (p = 0.026) and the preexisting AF (p = 0.028). Postsurgical ST changes were present in 30 patients and ST depression was correlated with age (p < 0.001), prolonged surgery time [150 (120-180) vs 120 (90-150) minutes (p < 0.001)], history of HBP [(33.3% vs 12.2%) (p=0.017)] and intraoperative maximum values of BP (p = 0.007). Conclusions: There is an increased risk of cardiovascular events during the postoperative period of non-cardiac surgery in patients with advanced age, pre-existing diseases (hypertension, preexisting atrial fibrillation, diabetes mellitus), the level of inflammation and longer intraoperative stress. Holter monitoring revealed rhythm and conduction disorders as well as ST segment changes that were associated with the inflammatory status and slightly elevated cardiac enzyme levels. Future studies are needed to see the impact of cardiac complications in the long term.
