Arterial hypertension and age

Pulmonary hypertension (PH) pathogenesis is driven by inflammatory and metabolic derangements as well as glycolytic reprogramming. Induction of both interleukin 6 (IL6) and transglutaminase 2 (TG2) expression participates in human and experimental cardiovascular diseases. However, little is known about the role of TG2 in these pathologic processes. The current study aimed to investigate the molecular interactions between TG2 and IL6 in mediation of tissue remodeling in PH. A lung-specific IL6 over-expressing transgenic mouse strain showed elevated right ventricular (RV) systolic pressure as well as increased wet and dry tissue weights and tissue fibrosis in both lungs and RVs compared to age-matched wild-type littermates...

INTRODUCTION: In the current times, fetal growth monitoring has become readily available with the help of Doppler ultrasound. Identification of pregnancies that are at risk for perinatal morbidity and mortality has been a primary goal of obstetric care. Doppler study is a fast, non-invasive test that provides significant information about the hemodynamic status of the fetus. It is an efficient diagnostic modality to assess fetal compromise, which helps in timely intervention in high-risk pregnancies for better perinatal outcomes...

BACKGROUND: Infra-malleolar disease is present in most diabetic patients presenting with tissue loss. Infra-malleolar (pedal) artery disease and pedal medial arterial calcification (pMAC) are associated with major amputation in patients with chronic limb-threatening ischemia (CLTI). This study aimed to examine the impact of pMAC on the outcomes after isolated infra-malleolar (pedal artery) interventions. METHODS: A database of lower extremity endovascular intervention for tissue loss patients between 2007 and 2022 was retrospectively queried...

BACKGROUND: The risk factor (RF) burden, clinical course, and long-term outcome among patients with atrial fibrillation (AF) aged <65 years is unclear. METHODS: Adult (n=67 221; mean age, 72.4±12.3 years; and 45% female) patients with AF evaluated at the University of Pittsburgh Medical Center between January 2010 and December 2019 were studied. Hospital system-wide electronic health records and administrative data were utilized to ascertain RFs, comorbidities, and subsequent hospitalization and cardiac interventions...

Background: Aortopulmonary window (APW) is a rare anomaly with variable morphology and associated cardiac anomalies. We evaluated impact of patient and operative factors on mid-term outcomes following APW repair. Methods: Twenty-nine patients underwent surgical APW repair at our institution from 1996 to 2022. Eight (28%) had simple APW, accompanied by only atrial septal defect or patent ductus arteriosus; 21 (72%) had complex APW with additional cardiovascular lesions, including nine with interrupted aortic arch...

Background Chemotherapy correlates to acute and long-term cardiotoxicity, is reflected clinically by myocardial and vascular endothelial dysfunction, and can cause cardiovascular complications. Thus, early diagnosis of cardiovascular disease in cancer patients undergoing anti-cancer treatment is necessary to enhance long-term survival. Our principal objective in this study was to discern the impact of specific anti-cancer chemotherapeutics and biologics on arterial stiffness alterations before and after the administration...

METHODS: One of the major COVID-19 centers in the western province of Saudi Arabia, the King Abdullah Medical Complex in Jeddah, was the site of this study. All adult COVID-19 patients who got a CT chest scan between January 2020 and April 2022 were included in the trial...

Objective: To explore the predictive value of pulmonary effective arterial elastance (Ea) in patients with heart failure (HF). Methods: This is a retrospective cohort study, which retrospectively included 284 patients with HF who underwent right heart catheterization at Heart Failure Center in Fuwai Hospital between September 2013 and February 2022. Data regarding baseline clinical characteristics, hemodynamic profiles, and prognosis were collected. Ea was calculated as mean pulmonary arterial pressure/stroke volume...

BACKGROUND: Right ventricular (RV) to pulmonary arterial (PA) coupling describes the ability of the RV to augment contractility in response to increased afterload. Several echocardiographic indexes of RV-PA coupling have been defined; however, the optimal numerator in the coupling ratio is unclear. We sought to establish which of these ratios is best for assessing RV-PA coupling based on their relationships with 6-minute walk distance (6MWD), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and the Kansas City Cardiomyopathy Questionnaire (KCCQ) in aging adults...

A comprehensive evaluation of risk, using multiple indices, is necessary to provide reliable prognostic information and guide therapy in pulmonary arterial hypertension (PAH). The current ESC/ERS guidelines suggest using a three-strata model for incident (newly diagnosed) patients and a four-strata model for prevalent patients with PAH. The four-strata model serves as a fundamental risk-stratification tool and relies on a minimal dataset of indicators that must be considered during follow-up. Nevertheless, there are still areas of vagueness and ambiguity when classifying and managing patients in the intermediate-risk category...

Cerebral microhemorrhages (CMHs, also known as cerebral microbleeds) are a critical but frequently underestimated aspect of cerebral small vessel disease (CSVD), bearing substantial clinical consequences. Detectable through sensitive neuroimaging techniques, CMHs reveal an extensive pathological landscape. They are prevalent in the aging population, with multiple CMHs often being observed in a given individual. CMHs are closely associated with accelerated cognitive decline and are increasingly recognized as key contributors to the pathogenesis of vascular cognitive impairment and dementia (VCID) and Alzheimer's disease (AD)...

UNLABELLED: Cardiovascular diseases and diabetes mellitus, debuting as arterial hypertension (AH) syndrome and prediabetes, are common types of chronic non-communicable processes, that are the leading cause of death in the world. The main treatment method for above mentioned disorders, according to the current guidelines, is pharmacotherapy. However, it is possible to effectively apply non-pharmacological correction methods, aimed at the probable etiological factor and inversive mechanism involved in AH maintenance, in the early stages when no permanent changes are maintaining a high level of blood hypertension (BH) and glycemia...

BACKGROUND: Heart failure with a preserved ejection fraction (HFpEF) is common in the elderly (≥75 years) and associated with arterial stiffness. The mean age of HFpEF presentation is lower (40-55 years) in sub-Saharan Africa. No clinical study has been conducted on HFpEF in identifying and characterising this phenotype at a younger age, moreover in a South African black population where the risk of HFpEF is two times higher than in other ethnic groups. This study investigated the characteristics of HFpEF in a black South African population, the biochemical markers that predict HFpEF and cardiac structural changes in this HF phenotype...

AIM: To determine the prevalence of some retinal pathologies in people over 60y and their association with demographic and ocular factors. METHODS: A cross-sectional study was conducted in Tehran using multistage cluster sampling. After selecting subjects aged 60 and over, optometric, and ophthalmic examinations were done. For retinal examination, a 90 D lens was used and indirect ophthalmoscopy was performed after instilling tropicamide drops. Biometry was done using the IOL Master for all participants...

BACKGROUND: Impaired quality of life (QoL) is prevalent among patients with chronic thromboembolic pulmonary hypertension (CTEPH) despite improved survival due to medical advances. We clarified the physical QoL of patients with CTEPH with mildly elevated pulmonary hemodynamics and evaluated its determinants using a database of patients with CTEPH evaluated for hemodynamics during exercise. METHODS: The QoL was measured in 144 patients with CTEPH (age, 66 (58-73) years; men/women, 48/96) with mildly elevated mean pulmonary artery pressure (< 30 mmHg) at rest after treatment with balloon pulmonary angioplasty and/or pulmonary endarterectomy using the Short-Form 36 (SF-36) questionnaire...

BACKGROUND: Data regarding the risk of atrial fibrillation (AF) during the post-acute phase of COVID-19 are lacking. OBJECTIVE: We assess the risk of incident AF in COVID-19 recovered patients by performing a systematic review and meta-analysis of the available data. METHODS: Following the PRIMSA guidelines, we searched Medline and Scopus to locate all articles published up to December 10, 2023, reporting the risk of AF in patients recovered from COVID-19 infection compared to non-infected patients who developed the arrhythmia over the same follow-up period...

Atherosclerosis, an immunoinflammatory disease of medium and large arteries, is associated with life-threatening clinical events, such as acute coronary syndromes and stroke. Chronic inflammation and impaired lipoprotein metabolism are considered to be among the leading causes of atherosclerosis, while numerous risk factors, including arterial hypertension, diabetes mellitus, obesity, and aging, can contribute to the development of the disease. In recent years, emerging evidence has underlined the key role of mitochondrial dysfunction in the pathogenesis of atherosclerosis...

BACKGROUND: Diabetes can lead to micro and macro-angiopathies. The peripheral arterial disease (PAD) is a serious and an incapacitating disease. It is still under-estimated and under-treated throughout the world, particularly in sub-Saharan Africa. Doppler ultrasound, and in particular ankle brachial index (ABI), can be used to detect it. The aim was to determine the prevalence of PAD to study the clinical and ultrasonographic aspects and to identify the determining factors. PATIENTS AND METHODS: This was a descriptive and analytical study over a period of 5 years, including a total of 782 diabetic patients hospitalised in the diabetology department of the CHU la Reference Nationale...

Scimitar Syndrome is part of a complex spectrum of congenital cardiovascular anomalies related to anomalous pulmonary venous return. Depending on the extent of involvement, treatment can be either expectant or surgical. Prognosis and survival have been controversial, with some results supporting early surgical management. This research aims to disclose the outcomes and describe the management, clinical and imaging characteristics of patients diagnosed with Scimitar Syndrome treated in a tertiary referral healthcare center...

INTRODUCTION: Cerebral blood flow (CBF) declines with age and abnormalities in CBF are associated with age-related cerebrovascular disease and neurodegeneration. Women have higher CBF than men, although this sex-difference diminishes to some extent with age in healthy subjects. The physiological drivers of these age/sex differences are uncertain, but might be secondary to age and sex-differences in haemoglobin (Hb) level. Hb levels are inversely correlated with CBF, are lower in women, and decline with age in men, but the interrelations between these factors have not been explored systematically either in healthy subjects or across the full age-range in patients with vascular risk factors...
