In this study, dictionary learning and expectation maximization reconstruction (DLEM) was combined to denoise 64-slice spiral CT images, and results of coronary angiography (CAG) were used as standard to evaluate its clinical value in diagnosing coronary artery diseases. 120 patients with coronary heart disease (CHD) confirmed by CAG examination were retrospectively selected as the research subjects. According to the random number table method, the patients were divided into two groups: the control group was diagnosed by conventional 64-slice spiral CT images, and the observation group was diagnosed by 64-slice spiral CT images based on the DLEM algorithm, with 60 cases in both groups. With CAG examination results as the standard, the diagnostic effects of the two CT examination methods were compared. The results showed that when the number of iterations of maximum likelihood expectation maximization (MLEM) algorithm reached 50, the root mean square error (RMSE) and peak signal to noise ratio (PSNR) values were similar to the results obtained by the DLEM algorithm under a number of iterations of 10 when the RMSE and PSNR values were 18.9121 dB and 74.9911 dB, respectively. In the observation group, 28.33% (17/60) images were of grade 4 or above before processing; after processing, it was 70% (42/60), significantly higher than the proportion of high image quality before processing. The overall diagnostic consistency, sensitivity, specificity, and accuracy (88.33%, 86.67%, 80%, and 85%) of the observation group were better than those in the control group (60.46%, 62.5%, 58.33%, and 61.66%). In conclusion, the DLEM algorithm has good denoising effect on 64-slice spiral CT images, which significantly improves the accuracy in the diagnosis of coronary artery stenosis and has good clinical diagnostic value and is worth promoting.

Qi Stagnation

Angina pectoris (AP) with coronary heart disease (CHD) is one of the common cardiovascular diseases in clinical practice, which can be classified as “chest paralysis” in Chinese medicine according to its symptoms, and it is described in many ancient documents. Ancient Chinese medicine believes that the main pathogenesis of the disease is poor blood flow leading to paralysis of the heart and veins, so it is often treated by activating blood and removing blood stasis. In this study, 120 patients with AP of CHD of Qi stagnation and blood stasis type were randomly divided into the observation (n = 60) and the control group (n = 60). In the control group, basic care, conventional treatment, and unselected copper acupuncture scraping were used, while in the observation group, copper acupuncture scraping was performed at the right time of the heart meridian (11 : 00–13 : 00) on the basis of the control group, and all patients received the treatment for a total duration of 4 weeks. We collected data on the traditional Chinese medical (TCM) syndrome score, frequency and duration of angina attacks, nitroglycerin dosage, inflammatory factor levels, and hematological indices pretreatment and posttreatment in both groups. Patients’ adverse effects during treatment were recorded, and the clinical efficacy and ECG efficacy in both groups were evaluated after 4 weeks. We used SPSS.20 statistical software to statistically analyze the above data, and the results showed that the clinical efficacy and ECG efficacy of the observation group were significantly higher than the control group posttreatment. After treatment, the TCM symptom score, angina attack frequency, attack duration and nitroglycerin dosage, serum interleukin-8 (IL-8), hypersensitive C-reactive protein (hs-CRP), and tumor necrosis factor-α (TNF-α) levels, whole blood viscosity (WBV), plasma viscosity (PV), fibrinogen (FIB), and hematocrit (Hct) were significantly lower in both groups compared with those posttreatment. And the observation group showed a greater decrease when compared with the control group. The results also showed that the overall incidence of adverse reactions was lower in both groups during the treatment period. The above results indicate that while ensuring high safety, the copper stone based on theory of midnight-noon ebb-flow can more effectively improve the symptoms and inflammatory response of the body and reduce the viscosity of the blood in AP with CHD of Qi stagnation and blood stasis, and it has better therapeutic effects.

The Relationship

Aim. To study the relationship between the levels of synthesis of reactive oxygen species (ROS) by platelets and neutrophils in patients with coronary heart disease (CHD) before and after coronary artery bypass grafting (CABG), depending on sensitivity to acetylsalicylic acid (ASA).Material and methods. The study included 95 patients with coronary artery disease who are indicated for CABG surgery. The control group consisted of 30 healthy donors. The antiplatelet therapy was stopped for at least 5 days before CABG. In the postoperative period, from the first day, all patients were received 100 mg of an enteric form of acetylsalicylic acid (ASA). Resistance to ASA was determined at the level of platelet aggregation with arachidonic acid ≥20% by optical agregometry at least at one observation point: before CABG, on 1-3 day and on 8-10 day after surgery. We evaluated the spontaneous and induced lucigenin-dependent chemiluminescence (CL) of platelets (ADP induction) and neutrophils (zymosan induction) by the exit time to maximum intensity (Tmax), maximum intensity (Imax) and area (S) under the CL curve.Results. 70.5% sensitive (sASA) and 29.5% resistant (rASA) to ASA patients were revealed. Prior to CABG, in sASA patients, the Imax of spontaneous and zymosan-induced neutrophil CL and CL platelet activity was increased relative to control values. Tmax of spontaneous platelet CL, Imax and S under the ADP-induced platelet CL curve were lower in sASA patients, if to compare with rASA patients. On the 1st and 8-10th day after CABG in sASA patients, the CL indicators of neutrophil and platelet activity also remained elevated compared to control values. On the 1st day after CABG decreased levels of S under the spontaneous CL curve of neutrophils in rASA patients was established compared with sASA patients, and increased levels of Imax and S under the curve of induced neutrophil CL were detected in comparison with the control range. In rASA patients, the values of Tmax of spontaneous platelet CL decreased in relation to the values detected in the control group and sASA patients. On the 8–10th day after CABG, most indicators of spontaneous and zymosan-induced CL neutrophils in rASA patients were also increased compared to control values. In rASA patients a positive correlation of Imax-induced CL was found (r=0.83) on the 1st day after CABG and negative correlations of Tmax of spontaneous CL (r=- 0.75) and S under the curve induced CL (r=-0.70) on the 8-10th day were detected between platelets and neutrophils.Conclusion. In sASA patients with coronary heart disease before and after CABG, a high level of synthesis of superoxide radical by neutrophils and platelets was detected. The relationship between the levels of the synthesis of superoxide radical by neutrophils and platelets was found only after CABG in rASA patients. Increased synthesis of superoxide radical due to metabolic and regulatory relationships in neutrophils and platelets stimulates pro-inflammatory processes in coronary artery disease and determines the sensitivity of platelets to ASA.

Objective. To investigate the characteristics of intestinal flora in patients with gastric cancer complicated by coronary heart disease and heart failure and the guiding value of probiotics intervention for clinical treatment. Methods. (1) One hundred and sixty-eight gastric cancer patients with complications of coronary heart disease and heart failure from August 2017 to December 2020 were selected as the observation group. A total of 125 patients with coronary heart disease treated at the same time were selected as control group 1, and 89 healthy subjects were selected as control group 2. Fecal samples were retained to extract the total RNA, and high-throughput sequencing was applied to complete the analysis of microbial diversity and structure differences, so as to obtain the biological species information of the specimens. (2) Patients in the observation group were randomly divided into two equal groups of 84 patients, namely, group A and group B. Group A was treated with conventional methods, and group B was combined with probiotics intervention on the basis of group A; then, the differences in the intestinal mucosal barrier between the two groups were compared. Results. The Chao, ACE, and Simpson index in the observation group were lower than those in control group 1 ( P < 0.05 ), and the Shannon index was higher than that in control group 1 ( P < 0.05 ). The Chao, ACE, and Shannon index in control group 1 were lower than those in control group 2 ( P < 0.05 ), whereas the Simpson index was higher than in control group 2 ( P < 0.05 ). The abundance of Bacteroidetes in the observation group was lower than that in control group 1 and control group 2 ( P < 0.05 ). The abundance of Firmicutes was higher than that of control group 1 and control group 2 ( P < 0.05 ). Four weeks after treatment, the levels of ET, D-lactic acid, and PCT in the group B were (0.10 ± 0.01), (3.99 ± 0.32), and (0.41 ± 0.10), respectively, which were lower than those in group A (0.19 ± 0.03), (4.51 ± 0.46), and (0.81 0.13). Conclusion. Gastric cancer patients with complications of coronary heart disease and heart failure are associated with intestinal flora disorder, which may be involved in the occurrence and development of the disease. Probiotics intervention is helpful to repair the intestinal mucosal barrier in patients, which is worthy of popularization and application.

Arterial Stiffness Index

Abstract Background Arterial stiffness index (ASI) is closely related to coronary atherosclerosis. This study aims to explore whether ASI can predict coronary heart disease (CHD) and its severity. Methods In this study, a total of 726 patients with suspected CHD were recruited. Based on coronary angiography results, the subjects were assigned into three groups: the control group (without obvious coronary artery disease), single-vessel disease group, and multi-vessel disease group (the number of vessels diseased ≥ 2). At the same time, according to the results of angiography, myocardial enzyme spectrum, electrocardiogram, color Doppler echocardiography and clinical manifestations, these patients were divided into four groups: the control group, stable angina (SA) Group, unstable angina (UA) group, and acute myocardial infarction (AMI) group. We have compared whether there were differences in ASI and related baseline data between groups. Receiver operating curve (ROC) analysis was conducted to determine whether ASI could predict CHD and evaluate the severity. Results ASI was positively correlated with the number of diseased branches of coronary artery. The value of ASI was increased as the number of the diseased branches increased. The ASI value in the SA group was significantly higher compared with the control group. Furthermore, the ASI value in the UA and AMI groups was remarkably increased compared with the control and SA groups. The results of ROC analysis indicated that the sensitivity and specificity of ASI was 71.0% and 85.4% in diagnosing CHD, respectively. While ASI was used in predicting the severity of CHD, the sensitivity was 72.1% and specificity 57.9%. Conclusion ASI is of great value in the diagnosis of coronary heart disease and the prediction of its severity.

Objective: To explore the significance of serum Retinol binding protein 4 (RBP4) and its relationship with coronary artery lesion in patients with senior coronary heart disease accompanying T2DM by determining the level of serum RBP4 and Gensini score.Methods: 30 cases of patients who were 60 years old above with coronary heart disease accompanying T2DM were selected and included in the experimental group, and 30 cases of patients of 60 years old above with coronary heart disease alone were included in the control group. Both groups of patients were given CAG examinations. In addition, Gensini score was calculated according to different degrees and parts of coronary artery lesion. It was required to record each patient’s age, gender, fasting blood glucose (FPG), triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), glycated hemoglobin (HbA1c) and other laboratory examination indexes. ELISA was used to detect the level of serum RBP4 in each group, and statistical analysis was performed to the data in each group.Results: (1) RBP4 level, GS score, FPG and LDL-C in the experimental group were all higher than those in the control group, and the difference was of statistical significance (p < .05). There was no statistically significant difference in age, gender, TC, TG and HDL-C between two groups. (2) RBP4 was positively correlated to FPG and HbA1c. (3) In patients with senior coronary heart disease accompanying diabetes mellitus, HbA1c was positively correlated to GS score, RBP4 and FPG. (4) RBP4 was a risk factor for coronary artery stenosis in patients with senior coronary heart disease accompanying diabetes mellitus.Conclusions: The level of serum RBP4 in patients with senior coronary heart disease accompanying diabetes mellitus is higher than that in patients with coronary heart disease alone, with a deeper degree of coronary artery lesion. The level of serum RBP4 is increased with the degree of lesion deepened in patients with senior coronary heart disease, suggesting that the level of serum RBP4 is expected to be an early predictor of coronary artery lesion for patients with senior coronary heart disease.

<p>Objective: To analyze and explore the clinical observation of coronary artery disease with coronary heart disease and coronary heart disease (CHD) undergoing coronary artery bypass grafting. Methods: From December 2015 to December 2016, 80 patients with coronary heart disease and heart valve were randomly divided into two groups: observation group and control group (40 cases). The observation group was treated with coronary artery bypass grafting combined with simultaneous heart valve replacement. The control group was treated with coronary stent implantation and non-synchronous valve replacement. The improvement of postoperative cardiac function, postoperative hospitalization, adverse events and bridge patency were compared between the two groups. Results: The improvement of cardiac function and the incidence of adverse events were significantly better in the observation group than in the control group (P &lt;0.05). The time of hospitalization and the time of ventilator were significantly shorter than those of the control group (P &lt;0.05). The patency rate of the bridge was significantly higher than that of the control group (P &lt;0.05). Conclusion: Coronary artery bypass grafting combined with heart valve replacement in patients with coronary heart disease complicated with valvular heart disease can achieve significant curative effect, which is more ideal and safer than coronary artery bypass surgery combined with non-synchronous valve replacement.</p>
