“…RV‐PA coupling was calculated according to the following formulas: RV‐PA coupling(mm/mmHg) = TAPSE/MPAP (Prins et al, 2016). PAS (kHz/s) was calculated according to the following formula: PAS = MFS/AT PA (Abacioglu et al, 2021; Görgülü et al, 2003; Öz et al, 2021). Subsequently, the right superior pulmonary vein from the apical four‐chamber view was found by adjusting the position of the transducer, so that the pulmonary vein opening can be clearly displayed.…”

Background: Pulmonary transit time (PTT) and pulmonary pulse wave transit time (pPTT) are useful parameters for the evaluation of cardiopulmonary circulation and vascular alterations, but their relationship remains unknown. The aim of this study was to investigate the correlation between PTT and pPTT.Methods: A total of 60 healthy volunteers were involved in this study. They were divided into two groups (30 participants per group): <50 years and >50 years. They all underwent Doppler echocardiography of pulmonary vein flow and contrast echocardiography with the measurement of pPTT and PTT, respectively. The correlation between PTT and pPTT was deduced.Results: Compared with Group of <50 years, there was a significant increment in left atrial volume index, left atrial pressure and pulmonary artery stiffness but a significant reduction in acceleration times of pulmonary artery flow in Group of >50 years (p < 0.05). Group >50 years had longer PTT and but reduced normalized PTT by R-R interval (NPTT), reduced normalized pPTT by R-R interval (NpPTT) than Group <50 years (p < 0.05), while there was no significant difference in pPTT between the two groups (p > 0.05). PTT and NPTT were all negatively correlated with pPTT and NpPTT. The statistically significant strongest correlation was observed between PTT and NpPTT (r = −0.886, p < 0.0001). The regression equation for them was y = 7.4396-13.095x (R 2 = 0.785; p < 0.001), where x and y represent NpPTT and PTT, respectively. Conclusion:PTT had close relation with pPTT in normal subjects. From the regression equation for them, we can get the value of PTT simply and easily by noninvasively measured pPTT.

Pulmonary hypertension (PH) is a pathophysiological disorder that may involve multiple clinical conditions and complicate most systemic diseases. Systemic Sclerosis (SSc), represents the leading cause of connective tissue disease (CTD) associated with PAH. Although SSc is a rare disease, it is associated with higher morbidity and early mortality than other rheumatological diseases due to developing SSc-associated interstitial pulmonary disease (ILD) and/or pulmonary arterial hypertension (PAH). The impact of the early diagnosis on the prognosis is evident. In this context, in our study, we aimed to investigate the early changes in pulmonary vascular bed by measuring pulmonary arterial stiffness (PAS) in SSc patients without overt PAH. Sixty-two SSc patients and fty-eight gender and agematched, healthy subjects enrolled in this cross-sectional observational study. SSc patients were evaluated in terms of disease duration and severity. Modi ed Rodnan skin score (mRSS) was calculated as disease severity index. Echocardiographic parameters were assessed and compared to the control group. Right Ventricular (RV) diameters, systolic pulmonary artery pressure (sPAP), and right ventricle myocardial performance index (RV-MPI) were signi cantly higher in the SSc group compared to the control group (p < 0.05). Tricuspid annular plane systolic excursion (TAPSE) and right ventricular fractional area change (RV-FAC) were signi cantly lower in the SSc group compared to the control group (p < 0.05). PAS value (25.5 ± 9.2 kHz/ms vs. 18.1 ± 7.4 kHz/ms, p <0.001) was signi cantly higher in the SSc group than in the control group. A statistically signi cant positive correlation relationship was detected between the PAS value and CRP, ESR, disease duration, mRSS. According to these results, in SSc patients, PAS as an inexpensive and easily applicable echocardiographic method might serve as a marker of early detection of PAH.

Purpose of Review The purpose of this paper is to review the results of studies from the last 3 years, presenting the current state of knowledge on the pathophysiological effect of polycystic ovary syndrome (PCOS) on the cardiovascular system, with cardiac involvement using non-invasive cardiovascular investigations. Recent Findings PCOS is a complex endocrine disorder that has a significant impact on the cardiovascular system. Recent studies confirm that PCOS increases the risk of cardiovascular disease (CVD) as well as the occurrence of cardiovascular events (CVE), including myocardial infarction (MI), coronary artery disease, and revascularization. These findings support the need for early screening and implementation of CVD prevention in women with PCOS. Summary Current evidence documents important and previously unrecognized mechanisms by which PCOS may adversely affect the cardiovascular system in affected women. Further studies are needed to in-depth characterisation of the cardiovascular phenotype of patients with PCOS. There is still a lack of studies using advanced cardiac imaging methods, including cardiac magnetic resonance imaging (CMR). Graphical Abstract
