Cardiac troponin I is associated with non-sustained ventricular tachycardia in patients with hypertrophic obstructive cardiomyopathy.

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
As highly sensitive and specific markers of myocardial damage, cardiac troponins were demonstrated to correlate with clinical parameters of patients with hypertrophic cardiomyopathy. However, the relationship between cardiac troponins and presence of non-sustained ventricular tachycardia (NSVT) in hypertrophic cardiomyopathy remains unclear. The aim of our study was to explore the association between serum cardiac troponin I (cTNI) and presence of NSVT in patients with hypertrophic obstructive cardiomyopathy (HOCM). A total of 309 HOCM patients were enrolled in our study. All participants underwent clinical evaluations, including collections of medical history, blood tests, 24-h Holter monitoring, echocardiography, and cardiac magnetic resonance imaging. There were 53 (17.2%) patients with NSVT and 256 patients without it. Compared to patients without NSVT, serum cTNI (P < 0.001) and plasma NT-proBNP (P = 0.042) were significantly higher in patients with NSVT. Moreover, cTNI and NT-proBNP were positively correlated with left atrial diameter, maximum wall thickness (MWT), left ventricular volume index and left ventricular mass index. In multivariable logistic analysis, log cTNI [odds ratio (OR) = 2.408, 95% confidence interval (CI) 1.108-5.325, P = 0.027], left ventricular end-diastole diameter (OR = 0.922, 95%CI 0.856-0.994, P = 0.034), MWT (OR = 1.131, 95%CI 1.035-1.235, P = 0.006) and left ventricular end-systole volume index (OR = 1.060, 95%CI 1.025-1.096, P = 0.001) were independent determinants of NSVT occurrence after adjustment for potential cofounders. Serum cTNI level was elevated in patients with NSVT. And it was independently associated with NSVT in patients with HOCM. Our results suggest that it may be more reasonable for HOCM patients with elevated serum cTNI to extend the time of Holter monitoring.
