Summary: This study compared the changes in pressure wave components between pregnancy-associated hypertension (PAH) patients and non-pregnant women and women with normal pregnancies (HP) using Wave Separation Analysis (WSA) and Pulse Wave Analysis (PWA). The results showed that PAH was associated with higher forward wave component (Pf), but not higher backward wave component (Pb), compared to NP and HP. PAH also showed lower reflection magnitude (RM) and index (RIx) compared to NP and HP.

Summary: Aortic blood pressure waveform-derived indexes provide valuable information beyond cardiovascular risk factors, but there are differences between techniques, recording sites, and analysis methods. Gender, body height, and age also affect these indexes. Therefore, specific reference intervals for gender, body height, and age are needed to accurately evaluate waveform-derived indexes.

Summary: This study compared office and ambulatory measurements of PWV and observed the changes in PWV after lifestyle modifications or initiation of antihypertensive medication. The results showed significant differences between office and ambulatory measurements, suggesting that the two methods are not interchangeable.

Summary: This study proposes a novel method for accurately estimating central blood pressure using only a single peripheral pressure measurement, without the need for additional clinical measurements. The method allows for the individualization of transfer functions to better capture changes in patient condition during disease progression and treatment.

Summary: The study evaluated the accuracy of the novel VascAssist 2 in estimating central blood pressure, showing that it is at least as accurate as existing techniques and can even be used in diabetic patients. Automated measurement significantly simplifies the application process without the need for operator training and can be reliably applied even in patients with arrhythmias.

Summary: This study demonstrates the advantages of non-invasive central blood pressure monitoring and validates the accuracy of different devices through comparison with invasive measurements. It also provides a novel method of validation using recognized gold standard transducers and highlights the potential for easily measuring pulse wave velocity during coronary angiography.

Summary: The study found that self-reported long-term water exercise training did not improve central hemodynamic variables in postmenopausal hypertensive women compared to sedentary ones. However, it is worth emphasizing that diastolic blood pressure levels were reduced in the trained group, potentially reducing cardiovascular outcomes.

Summary: Children with a family history of hypertension show higher blood pressure and early signs of hypertensive vascular changes before clinical symptoms appear. This study found that arterial stiffness, pulse wave velocity, and central blood pressure values were higher in normotensive children with hypertensive parents compared to the control group, suggesting potential early markers for hypertensive disease.

Summary: This study investigated the hemodynamic variations associated with the application of positive end-expiratory pressure (PEEP) in healthy subjects. The results showed that low levels of PEEP prolong diastolic phase and reduce systolic work of the heart.

Summary: A prospective randomized comparative placebo-controlled double-blind study was conducted to investigate the effects of a dietary supplement containing Siberian fir terpenes, limonene, alpha-linolenic acid, and vitamin E on arterial health. The study found that the supplement significantly reduced the biological age of the arteries.

Summary: This study compared the parameters, arterial stiffness, target organ damage, and renal profile between central blood pressure (CBP) and peripheral blood pressure (PBP) guided hypertension treatments. The intervention guided by CBP resulted in reductions in central diastolic blood pressure and augmentation index (AIx) compared to the peripheral group (PG). Additionally, the frequency of changed pulse wave velocity (PWV) and left ventricular mass index (LVMI) was lower in the CBP group.

Summary: In this paper, a new discriminant index is proposed to evaluate the wearing condition of a blood pressure pulse wave measurement device with small variability. The index is based on the ratio of the blood pressure pulse wave component to the noise component. The correlation coefficient between the index and the amplitude of the blood pressure pulse wave is 0.879, and the index reduces the coefficient of variation by 12.8%.

Summary: Arterial function and wall mechanical properties play crucial roles in circulation hemodynamics. A novel non-invasive method for determining vessel distensibility and elastic modulus was proposed and validated, showing comparable results to invasive techniques. This new approach holds potential for clinical applications.

Summary: The study revealed that PKARI alpha disulfide formation is significantly increased in response to I/R in both humans and mice, leading to enhanced AKAP binding and preferential localization to the lysosome. This redox-dependent regulation of lysosomal channels by PKARI alpha plays a critical role in protecting the heart from extensive injury and could serve as a novel target for cardioprotective therapeutics.

Summary: Using a mendelian randomisation approach, this study found evidence supporting a causal association between lifelong differences in ECG parameters representing longer atrial conduction times within the normal range and a lower risk of AF. These findings suggest the need for more individualised treatment strategies for AF.

Summary: This study reports the results of a Phase 2 trial using the SAP depleter miridesap and dezamizumab in the treatment of cardiac amyloidosis. The results showed that dezamizumab had no significant effect on improving cardiac function or removing cardiac amyloid deposits. Furthermore, treatment-associated rash and vasculitis were observed in the study.
