Abstract Background Chronic heavy cigarette smoking can affect the right ventriclular function. The standard echocardiography may not show early right ventricular functional changes, and a more sensitive measure is needed. The aim of this work was to evaluate the subtle subclinical effects of chronic heavy cigarette smoking on the right ventricular function. The study included 55 healthy asymptomatic chronic heavy cigarette smokers (smoking history of at least 5 pack-years and a daily cigarette consumption of at least 1 pack) and 35 healthy non-smoking control subjects. Patients underwent a full clinical assessment and a conventional as well as a 2D-speckle tracking transthoracic echocardiography of the right ventricle and data was compared between the 2 groups. Results The mean age was 32.9 ± 7.2 years in smokers and 30.9 ± 7.9 years in non-smokers (p = 0.227). The 2 groups showed comparable conventional right ventricular systolic and diastolic functions. Smokers showed a significantly lower (less negative) right ventricular global longitudinal strain (− 19.0 ± 3.2% vs. − 24.5 ± 3.5%, p < 0.001). Patients with a higher daily cigarette consumption showed a poorer right ventricular global longitudinal strain (p = 0.014). Conclusion Chronic heavy cigarette smoking can adversely affect the right ventricular function, a finding that can be easily missed by conventional echocardiography and can be better detected by the right ventricular speckle tracking.

Introduction: Right ventricle (RV) systolic function is an important determinant of cardiopulmonary outcomes in premature infants. Two-dimensional speckle tracking echocardiography (2DSTE) derived myocardial strain is a reliable measure of RV systolic function in premature infants, but lacks reference values for clinical application in premature infants. We aimed to determine the maturational (age- and weight- related) changes in RV strain to establish reference values in preterm infants from birth to one year corrected age (CA). Methods: RV peak global longitudinal strain (pGLS) and RV free wall longitudinal strain (FWLS) were measured in a prospective longitudinal study in 115 preterm infants (< 29 weeks at birth) at 24 and 72 hours of age (HOA), 32 and 36 weeks postmenstrual age (PMA), and one year (CA) by 2DTSE (GE EchoPac) from a RV-focus apical 4-chamber view using a validated protocol. Premature infants that developed chronic lung disease or had a hemodynamically significant PDA were excluded (n=65) from analysis for the reference values. Results: RV pGLS ranged from -16% at birth to -26% by one year CA and RV FWLS ranged from -18% at birth to -27% to one year CA in healthy preterm infants. RV pGLS and FWLS strain correlated with increasing weight (r=0.87, p < 0.001), PMA in weeks (r=0.85, p < 0.001; r=0.83, p < 0.001), but were independent of gestational age at birth (r=0.4, p=0.38; r=0.3, p=0.5). RV strain was significantly lower in preterm infants with bronchopulmonary dysplasia (p=0.004) at 32 and 36 weeks PMA, and one year CA (Figure). RV strain was independent of gender or need for mechanical ventilation. Conclusions: This study establishes reference values of RV global and free wall longitudinal strain and tracks their postnatal maturational changes in preterm infants. These measures increase from birth to one year CA and are linearly associated with increasing weight reflecting the postnatal cardiac growth as a contributor to the maturation of RV function.
