Objective To observe and analysis the features of images of fundus fluorescein angriography (FFA) in low-perfused retinopathy caused by cephalo-cervical peripheral vascular stenosis or occlusion. Methods The results of FFA of 27 patients diagnosed with carotid artery stenosis or occlusion by digital subtraction angiography (DSA) and examination of Doppler and vascular-pulsation were retrospectively analyzed. Result All of the patients had a delayed arm-retinal circulation duration from 20.0 to 81.08 seconds with the mean of 32.1 seconds; a delayed retinal arteriovenous filling duration from 6 to 64.0 seconds with the mean of 24.2 seconds. Delayed arm-retinal circulation duration and retinal a rteriovenous filling duration in 10 cases (37.0%); microangioma, vascular wall staining, nonperfused capillary area in 11 (40.7%); and anterior ischemic syndrome in 6 (22.2%) were found. In the 6 patients with anterior ischemic syndrome, 4 cases had narrow retinal artery, segmental changes of blood stream, vascular atresia, and abnormal arterio-venous anastomosis, and 2 cases had bold vascular loops. Conclusions The main manifestations of FFA in patients with low-perfused retinopathy are malperfusion and retinal ischemia, whose degrees relate to the extend of carotid artery stenosis or atresia, and the process of the disease.Serious retinal ischemia may combined with anterior ischemic syndrome.

Methods By Searching the CBM database in Chinese and Medline database in English, we collected the related articles and picked out the frequency of keywords, authors and core administrations, and built the matrix of keywords and authors. Finally we completed the visualized network by Ucinet. Results We successfully obtained the visualization of this subject. Chinese network contained three parts: evidence-based medicine, therapy and nursing, while English network also contained three parts: evidence-based medicine, therapy and treatment outcome. In the authors′ visualized network, Chinese authors had less cooperation and looser relationship compared with their counterparts overseas. The core administrations in china located in outstanding universities, and developed countries had the dominated roles in the world. Conclusions The development trend of evidence-based cardiovascular medicine in china is good, but still has some limitations compared with overseas studies. More emphasis should be put on strengthening core-area researching and research plan adjustment.
It has been found that the incidence of cardiovascular disease in patients with lower limb amputation is significantly higher than that in normal individuals, but the relationship between lower limb amputation and the episodes of cardiovascular disease has not been studied from the perspective of hemodynamics. In this paper, numerical simulation was used to study the effects of amputation on aortic hemodynamics by changing peripheral impedance and capacitance. The final results showed that after amputation, the aortic blood pressure increased, the time averaged wall shear stress of the infrarenal abdominal aorta decreased and the oscillatory shear index of the left and right sides was asymmetrically distributed, while the time averaged wall shear stress of the iliac artery decreased and the oscillatory shear index increased. The changes above were more significant with the increase of amputation level, which will result in a higher incidence of atherosclerosis and abdominal aortic aneurysm. These findings preliminarily revealed the influence of lower limb amputation on the occurrence of cardiovascular diseases, and provided theoretical guidance for the design of rehabilitation training and the optimization of cardiovascular diseases treatment.
Cardiovascular disease is the leading cause of death worldwide, accounting for 48.0% of all deaths in Europe and 34.3% in the United States. Studies have shown that arterial stiffness takes precedence over vascular structural changes and is therefore considered to be an independent predictor of many cardiovascular diseases. At the same time, the characteristics of Korotkoff signal is related to vascular compliance. The purpose of this study is to explore the feasibility of detecting vascular stiffness based on the characteristics of Korotkoff signal. First, the Korotkoff signals of normal and stiff vessels were collected and preprocessed. Then the scattering features of Korotkoff signal were extracted by wavelet scattering network. Next, the long short-term memory (LSTM) network was established as a classification model to classify the normal and stiff vessels according to the scattering features. Finally, the performance of the classification model was evaluated by some parameters, such as accuracy, sensitivity, and specificity. In this study, 97 cases of Korotkoff signal were collected, including 47 cases from normal vessels and 50 cases from stiff vessels, which were divided into training set and test set according to the ratio of 8 : 2. The accuracy, sensitivity and specificity of the final classification model was 86.4%, 92.3% and 77.8%, respectively. At present, non-invasive screening method for vascular stiffness is very limited. The results of this study show that the characteristics of Korotkoff signal are affected by vascular compliance, and it is feasible to use the characteristics of Korotkoff signal to detect vascular stiffness. This study might be providing a new idea for non-invasive detection of vascular stiffness.
Cardiovascular disease is a leading cause of death in Chinese population. It is of great significance to further explore the pathogenesis of cardiovascular diseases. Ferroptosis is a recently discovered iron-dependent and non-apoptotic form of regulated cell death, which exerts a regulatory role in a variety of biological events. Some studies have shown that ferroptosis plays an important role in the development of cardiovascular diseases. According to newly scientific reports, we summarized the mechanism and regulation in ferroptosis, and reviewed the results of ferroptosis in common cardiovascular diseases such as cardiac ischemia-reperfusion/myocardial infarction, cardiomyopathy, cardiac hypertrophy, atherosclerosis and abdominal aortic aneurysm.
Objective To evaluate the rationality of drug treatment for cardiovascular diseases in aged people and the effects of evidence-based practice. Methods Descriptive study was conducted to compare the therapies for the patients suffering from cardiovascular diseases before and after evidence-based practice by investigating drug use during 1998-1999 (211 cases) and 2002-2003 (211 cases). Results Among antihypertensive drugs, the ACEIs and diuretics played a more important role than before. CCBs and ACEIs were still the most frequently used drugs, and drug combination was more common, comparing to that before evidence-based practice. Lipid lowering drugs and ACEIs were used more common in coronary heart disease. Quality of life of patients was more emphasized and combination use of anti-anxiety drugs was adopted. When treating heart failure, β-receptor blockers, aldadinc and ACEIs were more frequently used. Conclusions After evidence-based practice, drug use is much more based on evidence instead of experience and textbook. As a result, the rate of reaching ideal blood pressure is higher than before. The rate of rational drug use before and after evidence-based practice has increased from 42% to 78%, respectively.
Objective To systematically evaluate anti-platelet effect of clopidogrel influenced by CYP2C192,3 polymorphism in patients with cardiovascular diseases, in order to provide references for its safe medication. Methods Literature was retrieved in electronic databases covering EMbase, PubMed, The Cochrane Library, CBM and CNKI from establishment dates to November, 2011. Observational studies and clinical trials were included, cross-checked, assessed and pooled for meta-analysis. meta-analysis was performed using the software RevMan 5.1. Results A total of 13 articles including 14 trials (n=36 855) were included. The results of meta-analysis showed that: a) there was no significant difference in the incidences of cardiovascular events between CYP2C192,3 carriers and CYP2C191 carriers; b) the risk of stent thrombosis in CYP2C192,3 carriers was significantly higher than that in CYP2C191 carriers (Plt;0.000 1), and the relative risk of CYP2C192,3 carriers increased 92% within one month (Plt;0.000 1); c) as for bleeding events, there were no significant differences between CYP2C192,3 carriers and CYP2C191 carriers. Conclusion Compared with CYP2C191 carriers, CYP2C192,3 carriers have a higher risk of stent thrombosis in clopidogrel-treated patients, but there are few differences in cardiovascular and bleeding events between the two carriers. Therefore, CYP2C192,3 carriers with cardiovascular diseases and ready to receive PCT are suggested to pay more attention to stent thrombosis when using clopidogrel. We propose that patients with cardiovascular diseases and ready to receive PCT should have CYP2C19 tests to determine the use of antiplatelet drug (clopidogrel) to avoid thrombus.
