Rationale: Takayasu arteritis (TAK) is an autoimmune disease that causes chronic inflammation targeting the aortic wall. Since many patients are resistant to steroid treatment, multiple immunosuppressants or interleukin-6 (IL-6) suppression therapy have served as treatment alternatives. However, there are very few reports on the effectiveness of biologics against inflammatory cytokines upstream of IL-6.

Patients with genetically-based hyperlipidemias exhibit a wide phenotypic variability. Investigation of clinical and biochemical features is important for identifying genetically-based hyperlipidemias, determining disease prognosis, and initiating timely treatment. We analyzed genetic data from 3374 samples and compared clinical data, lipid levels (low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol, triglycerides, and lipoprotein (a)), frequency, age at onset of coronary heart disease (CHD), and the severity of carotid and femoral atherosclerosis (plaque number, maximum stenosis, total stenosis, maximum plaque height, and plaque score) among patients with familial hypercholesterolemia (FH), familial dysbetalipoproteinemia (FD), polygenic hypercholesterolemia (HCL), severe HCL, and those without lipid disorders (n = 324).

Visual detection of pulselessness by carotid artery sonography - A prospective observational study among medical students.

Resuscitation

December 2024

Department of Anesthesiology and Intensive Care Medicine, University Hospital of Giessen and Marburg, Campus Marburg, Marburg, Germany. Electronic address:

Aim: This cross-sectional study aimed to determine whether medical students with little to no ultrasound experience could correctly distinguish between 'pulsation present' and 'no pulsation present' after a short introductory video on the subject using ultrasound videos of the common carotid artery (CCA).

Methods: Ultrasound videos (B-mode, M-mode, and Color Doppler) of pulsatile (systolic blood pressure 70-80 mmHg) and non-pulsatile (cardiopulmonary bypass surgery, clamped aorta) CCA were created. These were demonstrated to the medical students for a period of ten seconds - corresponding to the duration of the manual pulse palpation during cardiopulmonary resuscitation (CPR).

Background: In recent years, there have been numerous studies using Quality Intima-Media Thickness (QIMT) and Quantitative Arterial Stiffness (QAS) technology to evaluate various related factors and disease-induced changes in carotid artery (CA) elasticity. However, there is still a lack of research on the relationship between non-alcoholic fatty liver disease (NAFLD) and various indicators related to the CA. This study aimed to investigate the clinical significance of using QIMT and QAS techniques for comprehensive evaluation of CA intima-media thickness (IMT) and elasticity changes in NAFLD patients, and to analyze various factors influencing these variables.

Hibernating mammals experience severe hemodynamic changes over the torpor-arousal cycle, with oxygen consumption reaching peaks during the early stage of torpor to re-enter arousal. Melatonin (MT) can improve mitochondrial function and reduce oxidative stress and inflammation. However, the regulatory mechanisms of MT action on the vascular protective function of hibernators are still unclear.

To investigate the relationship between different obesity metabolic phenotypes and the incidence of new carotid artery plaque. The present study is a retrospective cohort study, collecting individuals from the Health Management Center of the Second Affiliated Hospital of Dalian Medical University who had two or more cervical vascular color ultrasound examinations and met the inclusion criteria from 2014 to 2022, and collected their baseline clinical data. According to whether the subjects were obese and had metabolic syndrome, they were divided into metabolically healthy non-obese group, metabolically unhealthy non-obese group, metabolically healthy obese group, and metabolically unhealthy obese group.

Background: The Anomalous Origin of the Right Coronary Artery from the Left Coronary Sinus (ARCA-LCS) is a rare congenital cardiac condition where the right coronary artery emerges from the left sinus instead of the right coronary sinus of Valsalva. The clinical significance of ARCA-LCS lies in its potential to cause myocardial ischemia or sudden cardiac death, particularly under physical exertion. In this case, a patient experienced sudden cardiac arrest during sexual activity, which has not previously been reported.

Long-term changes in carotid intima-media thickness according to baseline blood pressure level: J-STARS Echo study.

J Neurol Sci

December 2024

Department of Clinical Neuroscience and Therapeutics, Hiroshima University Graduate School of Biomedical and Health Sciences, Hiroshima, Japan; Department of Neurology, Iseikai Hospital, Osaka, Japan.

Background And Aims: We aimed to investigate long-term changes in carotid intima-media thickness (IMT) based on baseline blood pressure (BP) levels in non-cardioembolic stroke patients.

Methods: Patients aged 45-80 years with dyslipidemia who were not on statins before enrollment and had experienced a non-cardioembolic stroke were assigned to either the pravastatin group or the control group in a randomized trial. Patients were classified into three groups according to BP levels: normal BP (N-group: systolic BP [sBP] <140 mmHg and diastolic BP [dBP] <90 mmHg), highly elevated BP (G2 group: sBP ≥160 mmHg or dBP ≥100 mmHg), and mildly elevated BP (G1 group: the remaining patients).

Objectives: To evaluate the combination of novel colour Doppler ultrasound (CDUS), greyscale ultrasound (GSUS), and oscillometric indices of macroangiopathy in patients with idiopathic inflammatory myopathies (IIM). Second, to explore the associations between these imaging markers and both patient-related and disease-related characteristics, as well as traditional cardiovascular (CV) risk factors.

Methods: We conducted CDUS to evaluate arterial compliance markers, specifically the resistance (RI) and pulsatility (PI) indices, both in the common (CCA) and internal carotid arteries (ICA) of patients with IIM and healthy controls.

Background: Rheumatoid arthritis (RA) increases the risk of premature mortality, primarily due to cardiovascular diseases (CVD). While Systematic Coronary Risk Evaluation (SCORE) and its updated version SCORE2 are used to estimate CVD risk, these tools may not adequately capture the full cardiovascular risk profile in RA patients.

Objectives: This study aims to compare the effectiveness of SCORE2 versus SCORE in predicting the presence of carotid plaques or increased intima-media thickness (IMT), as detected by ultrasound, in RA patients.

Background: Changes in blood vessel properties have been identified with confinement, spaceflight, bedrest, and dry immersion. Subsequently, it was suspected that other organs may also be affected in these extreme environments. The purposes of the current study were to determine the effects of head-down bedrest (HDT) on cardiovascular and organ measurements made using ultrasound imaging similar to that currently available on the International Space Station, and to evaluate the efficacy of two different countermeasure protocols in preventing any observed changes in the ultrasound measurements with HDT.

Children requiring veno-arterial extracorporeal membrane oxygenation (VA ECMO) or cardiac surgery often undergo cervical cannulation or carotid artery clamping, which can interrupt cerebral circulation. Inadequate collateral flow through the circle of Willis (CoW) may lead to cerebral ischaemia within the vascular territory and/or watershed regions. Pre-cannulation survey of the CoW using transcranial Doppler (TCD) ultrasound may be performed to predict and plan neuroprotection.

Atherosclerotic plaque rupture is a major cause of cardiovascular events. Plaque destabilization is associated with extracellular matrix (ECM) modification involving proteases which generate protein fragments with new N-termini. We hypothesized that rupture-prone plaques would contain elevated fragment levels, and their sequences would allow identification of active proteases and target proteins.
