Cardiac rehabilitation may influence leptin and VEGF A crosstalk in patients after acute coronary syndrome

The Role of Carotid-Femoral Pulse Wave Velocity in a Metabolic Syndrome Patient with Sudden Cardiac Arrest: A Case Report

INTRODUCTION

Carotid-femoral pulse wave velocity reflecting aortic stiffness could be used as an independent predictor of future cardiovascular events for an individual with metabolic syndrome. However, the routine use of carotid-femoral pulse wave velocity is suboptimized in clinical practice. We report a case of metabolic syndrome with increased carotid-femoral pulse wave velocity and subsequently developed myocardial infarction and sudden cardiac arrest.

CASE PRESENTATION

A Polish man of an age between 40 and 50 years previously diagnosed with metabolic syndrome with essential hypertension, obesity, dyslipidaemia, and impaired glucose level. He developed myocardial infarction, ventricular fibrillation, and was successfully resuscitated with defibrillation. The patient showed high-normal traditional cardiovascular risk factors but an increased carotid-femoral pulse wave velocity. The increased carotid-femoral pulse wave velocity is associated with an increased arterial stiffness, which altered the myocardial perfusion and induced the anterior-lateral ST elevation myocardial infarction. The patient actively participated and completed the phase II cardiac rehabilitation programme. To the best of our knowledge, there have been few studies on carotid-femoral pulse wave velocity screening for patients with metabolic syndrome. Pulse wave velocity screening by a physician appears to be helpful in identifying the potential high-risk population with borderline traditional cardiovascular risk factors.

CONCLUSION

This trajectory highlights the clinical relevance of using carotid-femoral pulse wave velocity as an adjunct marker to assess the risk of cardiovascular event for patients with metabolic syndrome.

The Long-Term Effect of Maternal Obesity on the Cardiovascular Health of the Offspring-Systematic Review

Maternal obesity may affect offspring's cardiovascular health. Our literature search using PubMed, Web of Sciences included original English research and Google Scholar articles published over the past ten years, culminating in 96 articles in this topic. A mother's obesity during pregnancy has a negative impact on the cardiovascular risk for their offspring. Dependence was observed in relation to hypertension, coronary artery disease, stroke, and heart failure. The adverse impact of an abnormal diet in pregnant mice on heart hypertrophy was observed, and was also confirmed in human research. Pregnant women with obesity were at greater risk of having a child with innate heart disease than pregnant women with normal mass. To conclude: mother's obesity has a negative impact on the long-term cardiovascular consequences for their offspring, increasing their risk of high blood pressure, coronary heart disease, stroke and heart failure. It also increases the probability of heart hypertrophy and innate heart defects.

The driving mechanism and targeting value of mimicry between vascular endothelial cells and tumor cells in tumor progression

The difficulty and poor prognosis of malignant tumor have always been a difficult problem to be solved. The internal components of solid tumor are complex, including tumor cells, stromal cells and immune cells, which play an important role in tumor proliferation, migration, metastasis and drug resistance. Hence, targeting of only the tumor cells will not likely improve survival. Various studies have reported that tumor cells and endothelial cells have high plasticity, which is reflected in the fact that they can simulate each other's characteristics by endothelial-mesenchymal transition (EndMT) and vasculogenic mimicry (VM). In this paper, this mutual mimicry concept was integrated and reviewed for the first time, and their similarities and implications for tumor development are discussed. At the same time, possible therapeutic methods are proposed to provide new directions and ideas for clinical targeted therapy and immunotherapy of tumor.

The Effect and Possible Mechanism of Cardiac Rehabilitation in Partial Revascularization Performed on Multiple Coronary Artery Lesions

Purpose

To observe the effect of cardiac rehabilitation (CR) in patients with partial revascularization performed on multiple coronary artery lesions and explore its possible mechanism.

Patients and Methods

A total of 400 patients with multiple coronary artery lesions were enrolled and randomly divided into a complete revascularization group and a CR group, with 200 cases in each group. Target lesion revascularization was performed radically in the complete revascularization group, while it was partially completed in the CR group, and postoperative CR was performed. All the patients were put under conventional treatment. Left ventricular end diastolic dimension (LVEDD), left ventricular ejection fraction (LVEF), 6-minute walking distance (6-MWD), quality-of-life scores, safety and levels of serum nitric oxide (NO), nitric oxide synthase (NOS), superoxide dismutase (SOD), and vascular endothelial growth factor (VEGF) were evaluated and compared between two groups before and after training.

Results

There was no significant difference in LVEDD, LVEF, 6-MWD, quality-of-life scores, levels of serum NO, NOS, SOD, and VEGF between two groups before training (p>0.05). 1 year later, compared with the complete revascularization group, the occurrence of major adverse events in the CR group declined (p>0.05); the measurements of LVEDD decreased and LVEF increased (p>0.05), 6-MWD increased significantly (p<0.05), quality-of-life scores were higher (p<0.05), the levels of serum NO, NOS, and SOD increased noticeably, and the levels of serum VEGF decreased significantly in the CR group (p<0.05). There were significant differences within the same group, before and after training (p<0.05).

Conclusion

Cardiac rehabilitation training, not increase in the incidence of adverse events, is effective and safe after partial revascularization in patients with multiple coronary artery lesions, which has notable clinical advantages in promoting patients' exercise endurance and quality-of-life by improving the nitric oxide synthase system and antioxidant system and reducing the level of VEGF.
