Purpose: Type 2 diabetes mellitus (T2DM) is known to produce diabetic retinopathy (DR). Pulse wave analysis (PWA) provides arterial stiffness (AS) and central hemodynamic (CH) parameters. We studied the effect of DR on AS and CH parameters in type 2 diabetics (T2D).
Methods: We performed a cross-sectional study on 47 T2Ds attending a private ophthalmology clinic screened for DR by optical coherence tomography angiography and divided into NDR (non-DR), NPDR (non-proliferative DR), and PDR (proliferative DR). Mobil-o-graph (IEM, Germany) based oscillometric PWA yielded AS and CH parameters. They were further compared between groups stratified by DR with P value set at 0.05.
Results: Participants had a mean age 62, mean diabetes duration 9 years, high mean BMI, and high prevalence of physical inactivity, hypertension, and poor diseases control. Significant differences were lacking in NPDR, NDR, and PDR in rate pressure product (mean 112.71 vs 116.06 vs 119.57), central pulse pressure (mean 46.50 vs 43.09 vs 42.72), stroke work (mean 153.36 vs 132.36 vs 146.08), augmentation index (mean 29.43 vs 33.14 vs 31.64), and aortic pulse wave velocity (mean 10.06 vs 9.08 vs 9.06). There was no clear pattern of distribution of most parameters among the three subgroups.
Conclusion: We found a lack of association between DR and cardiovascular ageing studied by AS and hemodynamic parameters. It suggests a possible difference in risk factors for both of these aftermaths of T2DM and calls for further prospective studies with a large sample size.

Background: Use of health applications (apps) to support healthy lifestyles has intensified. Different app features may support effectiveness, including gamification defined as the use of game elements in a non-game situation. Whether health apps with gamification can impact behaviour change and cardiometabolic risk factors remains unknown.

Aim: This study aims to investigate the effects of combining a multifunctional pulse wave sphygmomanometer with constant temperature ice on patients with forearm hematoma following coronary intervention.
Methods: Patients who developed forearm hematoma after undergoing coronary intervention from March 2021 to March 2023 at our hospital were selected as the study cohort. Using a random number table, they were divided into two groups the control group and the research group.

Although the relationships between basic clinical parameters and white matter hyperintensity (WMH) have been studied, the associations between vascular factors and WMH volume in general populations remain unclear. We investigated the associations between clinical parameters including comprehensive vascular factors and WMH in two large general populations. This retrospective, cross-sectional study involved two populations: individuals who underwent general health examinations at the Asan Medical Center (AMC) and participants from a regional cohort, the Korean Genome and Epidemiology Study (KoGES).

Arterial stiffening is a hallmark of chronic kidney disease (CKD) related cardiovascular events and is primarily attributed to the elevated matrix stiffness. Stiffened arteries are accompanied by low-grade inflammation, but the causal effects of matrix stiffness on inflammation remain unknown. For analysis of the relationship between arterial stiffness and vascular inflammation, pulse wave velocity (PWV) and aortic inflammatory markers were analyzed in an adenine-induced mouse model of CKD in chronological order.

Background: Venous waveform analysis is an emerging technique to estimate intravascular fluid status by fast Fourier transform deconvolution. Fluid status has been shown proportional to , the amplitude of the fundamental frequency of the waveform's cardiac wave upon deconvolution. Using a porcine model of distributive shock and fluid resuscitation, we sought to determine the influence of norepinephrine on of the central venous waveform.
