Hypertension develops with increasing age primarily due to a disastrous feedback loop of increased arterial stiffness and maladaptive hemodynamics; this is compounded by age-related changes in physiology. The risk of adverse hypertension-related outcomes concurrently increases with age, and optimal blood pressure (BP) control in older adults thus becomes increasingly important each year. The results of several randomized clinical trials (RCTs) evaluating antihypertension strategies in older adults have concluded that the potential benefits of intensive BP management outweigh the risks of harm. However, the exclusion of frail, multimorbid, and institutionalized individuals limits the generalizability of such findings to the broader population of older patients with hypertension. Secondary analyses and external studies have continued to support intensive BP control strategies in older adults with frailty or sarcopenia. Therefore, based on available evidence, clinicians should continue practicing intensive BP control strategies in the older population, yet careful consideration of functional status, life expectancy, medication side effects, polypharmacy, and multimorbidity must take place to avoid unnecessary harm. Strategies must then be tailored to accommodate modifiers such as frailty and sarcopenia in older adults with hypertension. Knowledge gaps underscore the need for future studies evaluating BP management in older adults that incorporate greater proportions of multimorbid and institutionalized individuals with frailty, assess personalization of treatment, and identify subgroups in which optimal BP levels exist or the permissibility of higher BP levels is safer than BP reduction.</p>","PeriodicalId":74009,"journal":{"name":"Journal of vascular diseases","volume":"4 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12282481/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144692635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As arterial stiffness and endothelial injury are risk factors for coronary artery disease (CAD), these two indexes are therefore expected to predict and evaluate the future risk of CAD and cardiovascular events before clinical manifestations. Methods: A total of 90 consecutive patients with coronary angiography (CAG) were enrolled. After excluding normal patients and acute coronary syndrome patients, forty-seven patients with CAD and thirty-two patients with coronary atherosclerosis, and baseline characteristics data were collected. A multifunctional blood pressure monitoring device, AVE-1500 (Shisei Datum, Tokyo, Japan), was used to measure the AVI and API before CAG, and immediately and 2 h, 24 h, and 48 h after CAG and (or) PCI in all the selected participants. Results: After adjusting for various variables using stepwise multiple linear regression analyses, we found that the AVI in the CAD subjects was significantly higher than that in the coronary atherosclerosis subjects before CAG (p = 0.02), immediately after CAG/PCI (p = 0.01), and 48 h after CAG/PCI (p = 0.01), whereas the AVI decreased 24–48 h rather than immediately after CAG/PCI in the CAD group. Moreover, we also found that the API clearly changed in both groups during the periprocedural period of CAG (p = 0.01).

We investigated post-hospital-discharge arterial function at short- and mid-term intervals using pulse wave velocity. We assessed associations between arterial function, left ventricular diastolic and systolic function and left ventricular mass. Materials and methods: Retrospective data collection was carried out on 28 patients with MIS-C with at least two outpatient pediatric cardiology clinic visits post hospital admission. The patients underwent assessment of systemic arterial function and cardiac function. Data included pulse wave velocity between carotid and femoral arteries and echocardiographic assessment of left ventricular systolic function (shortening and ejection fraction, longitudinal strain), diastolic function and left ventricular mass. Results: Pulse wave velocity significantly decreased from visit 1 to visit 2 (5.29 ± 1.34 m/s vs. 4.51 ± 0.91 m/s, p = 0.009). Left ventricular mass significantly decreased from visit 1 to visit 2 (42 ± 9 g/m2.7 vs. 38 ± 7 g/m2.7, p = 0.02). There was a significant negative correlation between the pulse wave velocity and E/A mitral inflow (−0.41, p < 0.05).

Over time, plaque buildup narrows the coronary arteries, reducing blood flow to the heart muscle and resulting in myocardial ischemia. Timely diagnosis and intervention are crucial for restoring the blood flow to the heart muscle and preventing myocardial infarction. Given the limited availability of screening and diagnostic tests, the early diagnosis of myocardial ischemia remains challenging. While cardiac troponin is considered the gold standard for detecting myocardial injury, its effectiveness in identifying myocardial ischemia is limited. Ischemia-modified albumin (IMA) is a modified albumin variant that serves as a sensitive and early marker for ischemia. Despite extensive research on diagnostic applications of IMA as a biomarker for ischemia, significant gaps remain in understanding its formation, sensitive and specific detection, and precise clinical utility. This review aims to address these gaps by compiling literature on IMA discussing the latest findings on structure and formation, and detection methods. Further research is required to enhance understanding of the structure and formation of IMA, aiming to develop novel detection techniques or improve existing ones. However, currently, available sophisticated methods are associated with higher expenses and require specialized equipment and qualified personnel.","PeriodicalId":74009,"journal":{"name":"Journal of vascular diseases","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141668639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recognizing the systemic nature of atherosclerosis and its link with major cardiovascular events in coronary disease, this study evaluated PVAT attenuation in the peripheral arteries using CT imaging to expand the understanding of its diagnostic and prognostic potential. Methods: a retrospective analysis of 53 consecutive patients who underwent CT angiography, examining PVAT density across five primary peripheral arterial segments. A 5 mm region of interest adjacent to the vascular wall was analyzed by two blinded readers, with reproducibility coefficients calculated to determine the reliability of the measurements. For the statistical analyses, mean values were derived from these measurements. The patients were stratified into four groups based on the degree of arterial stenosis: <25%, 25–50%, 50–70%, and >70%. PVAT density comparisons between these groups were performed using the Kruskal–Wallis test and the pairwise Mann–Whitney U test with Holm–Bonferroni correction for multiple comparisons. Results: the Kruskal–Wallis test revealed statistically significant disparities in PVAT density across the categorically differentiated stenosis groups (p < 0.001), indicating an association between PVAT density and arterial stenosis severity. This association was especially pronounced in the external iliac, common femoral, superficial femoral, and popliteal arteries, where the p-values were consistently below 0.05. Subsequent pairwise analyses utilizing the Mann–Whitney U test with Holm–Bonferroni correction affirmed these findings, in particular for the external iliac, common femoral, superficial femoral and popliteal arteries (p < 0.05).
