Impact of Asthma Phenotypes on Myocardial Performance and Pulmonary Hypertension in Children and Adolescents With Moderate to Severe Persistent Asthma.

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
backgroundAsthma is characterized by chronic inflammation and remodeling of pulmonary vessels and airway wall resulting in pulmonary hypertension (PH). Increased afterload on right ventricle (RV) myocardium leads to RV diastolic dysfunction (RVDD). Echocardiography is an excellent tool to detect these changes early. Using echocardiography, we assessed the impact of clinical asthma phenotypes on myocardial performance and PH in children with asthma. MATERIALS AND
methodsSixty children with moderate or severe persistent asthma and 60 age and gender-matched healthy controls were enrolled. As per clinical phenotypes, children with asthma were classified into early wheezers (n = 30) and late wheezers (n = 30). Pulmonary function tests (PFT) and echocardiography, both conventional and pulse wave (PW), were performed.
resultsChildren with asthma had significant RVDD and higher incidence (33%) of PH. Myocardial performance index (MPI) was poor in asthmatics, 0.41 (0.04) compared to controls, 0.38 (0.03). Measures for PH such as tricuspid regurgitation (TR) gradient, TR velocity, and pulmonary artery pressure (PAP) were significantly higher in cases. Among clinical asthma phenotypes, there was no difference in left ventricular ejection fraction (LVEF) between early 64.3% (4.6) and late wheezers 65.6% (4.4). MPI was better in late wheezers at 0.41 (0.05) than in early wheezers at 0.40 (0.03). TR gradient, TR velocity, and PAP were significantly higher in early wheezers. The odds ratio for the development of PH was 0.74 (CI 0.25 - 2.17), and for the development of RVDD was 3.2 (CI 0.77 - 13.8), both in favor of early wheezers.
conclusionChildren with asthma, particularly early-onset wheezers are at increased risk of developing PH and RVDD. We suggest annual screening by conventional echocardiography and pulse wave Doppler imaging for early diagnosis and timely initiation of management.
