Background: Adenoid hypertrophy (AH) leads to chronic upper airway obstruction. Upper airway obstruction may cause pulmonary hypertension and right ventricle dysfunction. Mean platelet volume (MPV) may be used as a marker of platelet activation and it is shown that MPV is related to cardiovascular disorders. We investigated in our study if MPV is correlated with adenoid size and can be used as an indicator of obstruction due to adenoid hypertrophy. Methods: 95 children with AH and 99 healthy controls were enrolled in the study. White blood cell, hemoglobin, platelet, Mean platelet volume (MPV) levels were measured before adenoidectomy. Lateral cephalometric graphs were obtained from all patients to measure adenoid/nasopharynx ratio (A/N). The distance between the outermost point of convexity of adenoid shadow and basiocciput was divided to the distance between sphenobasiocciput and posterior end of the hard palate. A/N ratio and MPV levels have been correlated by using Pearson correlation test. Results: There were 45 male and 50 female patients between the ages of 2 and 14 years (mean age: 6.47 ± 2.44). There were no significant differences between children with AH and controls regarding white blood cell, hemoglobin, platelet, MPV and A/N ratio. We didn't detect any correlation between MPV levels and A/N ratio. Conclusion: MPV level was in normal limits in AH children and there was no significant relation between MPV and adenoid severity.

“…Chronic alveolar hypoxia may lead to hypoxemic pulmonary vasoconstriction within time, which may result in hypertension and right ventricular heart failure (6,13,14). Chronic upper airway obstruction will increase the pressure load of the right ventricle and this in turn will lead to hypertrophy and subendocardial ischemia by increasing the RV wall tension, which eventually ends up with RV dysfunction (15).…”

Objective: The aim of this study was to assess the right ventricular functions in patients with nasal polyposis using the strain (S) and strain rate (SR) echocardiography. Methods: A prospective, cross-sectional observational study was performed. The study included 40 patients with nasal polyposis (NP) (Group 1), and 25 healthy controls (Group 2). The study comprised patients with Stage 2 and Stage 3 nasal obstruction and no symptoms that could be associated with right ventricular heart failure. Longitudinal peak systolic strain (PSS) and peak systolic strain rate (PSSR) were measured from the basal-mid and apical segments of the right ventricle free wall. Student's t-test, Pearson's correlation analysis and Bland-Altman test were used for statistical analysis. Results: Pulmonary arterial systolic pressure was significantly higher in group 1 than group 2 (31.2±5.8, 19.7±4.3, respectively, p<0.001). PSS and PSSR values at the basal, mid and apical segments of the right ventricular lateral wall of the group I were significantly lower compared to the control group (p<0.001, p=0.002 and p=0.002 for PSS, p=0.003, p<0.001 and p<0.001 for PSSR, respectively). The comparison of Stage 2 and Stage 3 NP patients revealed a significant difference only in the SR measurement of the right ventricular mid segment (p=0.002). There was a significant correlation between the systolic pulmonary arterial pressure (sPAP) and right ventricular S and SR values (p<0.001). Conclusion: In this study, S/SR echocardiography showed a subclinical deficit of the right ventricular longitudinal functions in patients with NP who are considered to have normal right ventricular functions.

“…Hypoxia may result in respiratory acidosis which in turn may lead to pulmonary artery vasoconstriction and increased RV dysfunction. Pulmonary vascular resistance was clearly increased to maintain cardiac output and resulted in a dialated RV, increased pulmonary pressure and the development of cor pulmonae [2,5]. Symptoms of PH may not be obvious until severe cardiac decompensation [10].…”

“…Conventional Doppler was used in this previous study [29]. TDE provides direct quantitative information on myocardial function and can be a guide for treatment in terms of response and follow up [5]. TDE is minimally affected by cardiac geometry compared to Conventional Doppler and can provide an objective evaluation of RV global functions [5].…”

“…Severe upper respiratory tract obstruction may have an effect on chronic alveolar hypoventilation, which consequently may lead to right ventricle (RV) dysfunction induced by hypoxemic pulmonary vasoconstriction. This RV dysfunction may result in increased pulmonary vascular resistance and pulmonary artery pressure (PAP) [5]. Echocardiography is one of the most important noninvasive methods to diagnose for structural heart disease in children [6].…”
