Sympathectomy, as an emerging treatment method for cardiovascular diseases, has received extensive attention in recent years. Stereotactic radiotherapy (SRT), a precise and noninvasive therapeutic technique, has gradually been introduced into interventions targeting the sympathetic nervous system and has shown promising prospects in the management of cardiovascular conditions. Using three-dimensional imaging, SRT can accurately localize sympathetic ganglia and deliver high-energy radiation to disrupt nerve fibers, thereby achieving effects similar to conventional sympathectomy while reducing surgery-related complications and shortening recovery time. It also offers the advantages of being noninvasive and causing fewer adverse effects, and thus holds potential as an alternative to traditional approaches in the future. The integration of SRT with sympathectomy opens new avenues for the treatment of cardiovascular diseases and presents broad clinical application prospects.

Vascular aging refers to the degenerative changes in vascular wall structure and vasodilatory function, forming the pathophysiological basis for the onset and progression of cardiovascular disease (CVD). Pulse wave velocity (PWV), a non-invasive method for evaluating and detecting early vascular aging, has achieved significant results in predicting CVD risk and evaluating the efficacy of pharmacological treatments. PWV can effectively predict CVD risk across various populations, including healthy individuals, patients with hypertension, diabetes, and chronic inflammatory diseases. In patients with comorbidities such as hypertension, pharmacological interventions, such as anti-inflammatory, lipid-lowering, anti-hypertensive, and anti-diabetic treatments, can effectively reduce PWV and thus slow down vascular aging. Therefore, PWV is not only a vital tool for assessing early vascular aging but also an important indicator for evaluating treatment outcomes. Regular monitoring of PWV levels is of great significance in predicting CVD risk, evaluating therapeutic efficacy, and guiding clinical decision-making.

Clinical trials and animal experimental studies have demonstrated an association of arterial baroreflex impairment with the prognosis and mortality of cardiovascular diseases and diabetes. As a primary part of the arterial baroreflex arc, the pressure sensitivity of arterial baroreceptors is blunted and involved in arterial baroreflex dysfunction in cardiovascular diseases and diabetes. Changes in the arterial vascular walls, mechanosensitive ion channels, and voltage-gated ion channels contribute to the attenuation of arterial baroreceptor sensitivity. Some endogenous substances (such as angiotensin II and superoxide anion) can modulate these morphological and functional alterations through intracellular signaling pathways in impaired arterial baroreceptors. Arterial baroreceptors can be considered as a potential therapeutic target to improve the prognosis of patients with cardiovascular diseases and diabetes.

Circadian rhythms widely exist in living organisms, and they are regulated by the biological clock. Growing evidence has shown that circadian rhythms are tightly related to the physiological function of the cardiovascular system, including blood pressure, heart rate, metabolism of cardiomyocytes, function of endothelial cells, and vasoconstriction and vasodilation. In addition, disruption of circadian rhythms has been considered as one of the important risk factors for cardiovascular diseases, such as myocardial infarction. This review summarizes the recent research advances in the relationship between circadian clock and cardiovascular diseases, hoping to improve treatment strategies for patients with cardiovascular diseases according to the theory of biological clock.

OBJECTIVETo clarify the role of waist circumference (WC) in estimating organ damage and assessing the prognosis in young and middle-aged patients with cardiovascular disease undergoing cardiac rehabilitation program (CRP).

METHODSWe recruited 147 young and middle-aged patients with cardiovascular disease to participate in the CRP for 4 or 5 weeks. The baseline clinical data and results of routine fasting blood test and ultrasonic cardiography were evaluated for these patients.

RESULTSWC had a linear correlation with the indices reflecting cardiac structure alteration (LVSd and LVPWd) of the patients after CRP but showed a negative correlation with their HDL-C levels. The fasting blood glucose (FBG) and serum uric acid (UA) levels showed a positive correlation with WC before CRP but not after CRP.

CONCLUSIONWC monitoring allows accurate assessment of organ damage in patients undergoing CRP after cardiovascular disease and has special value in evaluating the changes in cardiac structure and function.

INTRODUCTIONWe assessed the local prevalence, characteristics and 10-year outcomes in a heart failure (HF) cohort from the emergency room (ER).

MATERIALS AND METHODSPatients presenting with acute dyspnoea to ER were prospectively enrolled from December 2003 to December 2004. HF was diagnosed by physicians' adjudication based on clinical assessment and echocardiogram within 12 hours, blinded to N-terminal-pro brain natriuretic peptide (NT-proBNP) results. They were stratified into heart failure with preserved (HFPEF) and reduced ejection fraction (HFREF) by left ventricular ejection fraction (LVEF).

RESULTSAt different cutoffs of LVEF of ≥50%, ≥45%, ≥40%, and >50% plus excluding LVEF 40% to 50%, HFPEF prevalence ranged from 38% to 51%. Using LVEF ≥50% as the final cutoff point, at baseline, HFPEF (n = 35), compared to HFREF (n = 55), had lower admission NT- proBNP (1502 vs 5953 pg/mL, P <0.001), heart rate (86 ± 22 vs 98 ± 22 bpm, P = 0.014), and diastolic blood pressure (DBP) (75 ± 14 vs 84 ± 20 mmHg, P = 0.024). On echocardiogram, compared to HFREF, HFPEF had more LV concentric remodelling (20% vs 2%, P = 0.003), less eccentric hypertrophy (11% vs 53%, P <0.001) and less mitral regurgitation from functional mitral regurgitation (60% vs 95%, P = 0.027). At 10 years, compared to HFREF, HFPEF had similar primary endpoints of a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, and rehospitalisation for congestive heart failure (CHF) (HR 0.886; 95% CI, 0.561 to 1.399; P = 0.605), all-cause mortality (HR 0.663; 95% CI, 0.400 to 1.100; P = 0.112), but lower cardiovascular mortality (HR 0.307; 95% CI, 0.111 to 0.850; P = 0.023).

CONCLUSIONIn the long term, HFPEF had higher non-cardiovascular mortality, but lower cardiovascular mortality compared to HFREF.

The aim of the study was to examine lipid profiles, arterial stiffness (AS), carotid intima-media thickness (cIMT), in 55 women with RA without overt cardiovascular disease (capital ES, CyrillicVD) treated with rituximab (RTX).The following parameters were recorded before and 24 weeks after RTX therapy (2 infusions of 500 or 1,000 mg RTX intravenously, fortnightly): plasma total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides, DAS 28-ESR, serum C-reactive protein (CRP), RF IgM, AS (SI - stiffness index, RI - reflection index) by digital volume pulse contour analysis (Micro Medical, UK), and common cIMT by high-resolution B-mode carotid ultrasound. Based on the European League Against Rheumatism (EULAR) criteria, patients were divided into two groups: 1) moderate/good response to RTX therapy after 24 weeks (41 patients, 75%), 2) no response to RTX therapy (14 patients, 25%). Effective RTX therapy resulted in 9% increase in TC, 23% increase in HDL-C and 14% decrease in atherogenic index, 57% decrease in SI and 24% decrease in RI. We observed a 9% decrease of cIMTmax at 24 weeks. The improvement of cardiovascular parameters was accompanied by statistically significant decreases of CRP, ESR, RF IgM and DAS 28 in group 1 (P < 0.05). There were not significant changes in lipid profile, AS parameters, and cIMT in group 2. Two infusions of RTX in case of moderate/good EULAR effect of therapy exerted favorable effects on lipid profile, AS and cIMT in women with RA without overt CVD.

By studying the relationship between fingertip temperature changes and arterial function during vascular reactivity test, we established a new non-invasive method for detecting vascular function, in order to provide an assistance for early diagnosis and prevention of cardiovascular diseases. We customized three modules respectively for blood occlusion, measurement of finger temperature and blood oxygen acquisition, and then we established the hardware of data acquisition system. And the software was programmed with Labview. Healthy subjects [group A, n = 24, (44.6 ± 9.0) years] and subjects with cardiovascular diseases [group B, n = 33, (57.2 ± 9.9) years)] were chosen for the study. Subject's finger temperature, blood oxygen and occlusion pressure of block side during and after unilateral arm brachial artery occlusion were recorded, as well as some other regular physiological indexes. By time-domain analysis, we extracted 12 parameters from fingertip temperature signal, including the initial temperature (Ti), temperature rebound (TR), the time of the temperature recovering to initial status (RIt) and other parameters from the finger temperature signal. We in the experiment also measured other regular physiological body mass index (BMI), systolic blood pressure (SBP), diastiolic blood pressure (DBP) and so on. Results showed that 8 parameters difference between the two group of data were significant. based on the statistical results. A discriminant function of vascular function status was established afterwards. We found in the study that the changes of finger temperature during unilateral arms brachial artery occlusion and open were closely related to vascular function. We hope that the method presented in this article could lay a foundation of early detection of vascular function.
