RESUMO
BACKGROUND: Vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) modulate atherosclerosis by promoting leukocyte infiltration, neutrophil recruitment, endothelial cell proliferation, etc., which may directly or indirectly facilitate the occurrence of major adverse cardiac events (MACE). This study intended to investigate the value of VCAM-1 and ICAM-1 for predicting MACE in ST-segment elevation myocardial infarction (STEMI) patients. METHODS: Totally, 373 STEMI patients receiving the percutaneous coronary intervention and 50 health controls (HCs) were included. Serum VCAM-1 and ICAM-1 were detected by ELISA. Meanwhile, MACE was recorded during a median follow-up of 18 (range: 1-46) months in STEMI patients. RESULTS: Vascular cell adhesion molecule-1 and ICAM-1 were raised in STEMI patients compared with HCs (both p < 0.001). VCAM-1 (p = 0.002) and ICAM-1 (p = 0.012) high were linked with raised accumulating MACE rate in STEMI patients. Notably, VCAM-1 high (hazard ratio [HR] = 2.339, p = 0.031), age ≥ 65 years (HR = 2.019, p = 0.039), history of diabetes mellitus (DM) (HR = 2.395, p = 0.011), C-reactive protein (CRP) ≥ 5 mg/L (HR = 2.550, p = 0.012), multivessel disease (HR = 2.561, p = 0.007) independently predicted MACE risk in STEMI patients. Furthermore, a nomogram-based prediction model combining these factors was established, exhibiting an acceptable value for estimating 1, 2, and 3-year MACE risk, with AUC of 0.764, 0.716, and 0.778, respectively, in STEMI patients. CONCLUSION: This study confirms the value of VCAM-1 and ICAM-1 measurement in predicting MACE risk in STEMI patients. Moreover, VCAM-1 plus other traditional prognostic factors (such as age, history of DM, CRP, and multivessel disease) cloud further improve the predictive accuracy of MACE risk in STEMI patients.

BACKGROUND Vitamin D (VD) deficiency and local inflammation of plaque are potential new risk factors and prevention goals for coronary heart disease (CHD). MATERIAL AND METHODS This study included 135 CHD patients and 45 chest tightness or chest pain patients (control group). Basic clinical data and serum 25-OH-VD, TNF-α, IL-6, IL-8, and IL-1ß of the 2 groups were compared by SPSS 25.0. A CHD rat model was used to explore the potential molecular mechanisms. RESULTS The serum 25-OH-VD level in the control group was significantly higher compared to the CHD group, and decreased with the worsening of the CHD condition. Logistic regression found that serum 25-OH-VD was a protective factor in the occurrence of CHD. In CHD patients, the level of serum 25-OH-VD had a negative correlation with serum TNF-α (r=-0.651, P<0.001), IL-6 (r=-0.457, P<0.001), IL-8 (r=-0.755, P<0.001), and IL-1ß (r=-0.628, P<0.001). In animal experiments, VD deficiency enhanced the level of serum TC, TG, and LDL-C. VD deficiency could increase the inflammatory response by upregulating the expression of p65 protein and reducing SIRT1 protein expression in heart tissue, thereby inducing or aggravating the state of CHD. CONCLUSIONS Serum 25-OH-VD was a protective factor in the occurrence of CHD, and VD deficiency could induce or aggravate the state of CHD by enhancing inflammation through the NF-κB pathway.

RESUMO
OBJECTIVE: To explore the influence of CYP2C19 gene combined with platelet function test on clinical prognosis of patients with complex coronary artery disease receiving antiplatelet therapy after PCI. METHODS: A total of 200 patients undergoing PCI in our hospital due to complex coronary artery disease from February 2019 to February 2021 were selected and divided into the control group and the observation group according to whether CYP2C19 gene detection was performed. The control group was treated with dual antiplatelet therapy of classical aspirin combined with clopidogrel, and the observation group was treated with individual antiplatelet therapy. The patients in the two groups were followed up for 1 year after PCI, and their quality of life was assessed using the Seattle Angina Questionnaire (SAQ score). The occurrence of major adverse cardiovascular events (MACE) during the follow-up period was also recorded. RESULTS: The incidence of total MACE events in the observation group was slightly less than that in the control group, and the difference was statistically significant (P = 0.040). In particular, the observation group was superior to the control group in reducing the readmission rate of recurrent unstable angina pectoris, and the difference was statistically significant (P = 0.023). The location of coronary culprit lesions with recurrent ischemic events was commonly seen in non-interventional target lesions (interventional/non-interventional target sites: 12.9%: 77.1%). The SAQ score in the observation group was larger than that in the control group, and the difference was statistically significant (P = 0.012). There was no statistical difference in the incidence of major bleeding between the two groups (P = 0.352). CONCLUSION: Using CYP2C19 genotype combined with platelet function test to guide individualized antiplatelet therapy after complex coronary artery PCI is beneficial to reducing ischemic events in a short period (1 year), mainly due to reducing the risk of readmission for recurrent unstable angina pectoris, and improving the quality of daily life of patients without increasing the risk of massive hemorrhage, which can improve clinical prognosis.
RESUMO
Background: In percutaneous coronary intervention (PCI) era, more clinically valuable risk factors are still needed to determine the occurrence of cardiac rupture (CR). Therefore, we aimed to provide evidence for the early identification of CR in ST-segment elevation myocardial infarction (STEMI). Methods: A total of 22,016 consecutive patients with STEMI admitted to Cangzhou Central Hospital and Tianjin Chest Hospital from January 2013 to July 2021 were retrospectively included, among which 195 patients with CR were included as CR group. From the rest 21,820 STEMI patients without CR, 390 patients at a ratio of 1:2 were included as the control group. A total of 66 patients accepted PCI in the CR group, and 132 patients who accepted PCI in the control group at a ratio of 1:2 were included. The status of first medical contact, laboratory examinations, and PCI characteristics were recorded. Multivariate logistic regression analysis was used to investigate the risk factors related to CR. Results: There was a higher proportion of patients with myocardial infarction (MI) in the high lateral wall in the CR group (23.6% vs. 8.2%, P<0.001). The proportion of single lesions was lower in the CR group (24.2% vs. 45.5%, P=0.004). Female (OR =2.318, 95% CI: 1.431-3.754, P=0.001), age (OR =1.066, 95% CI: 1.041-1.093, P<0.001), smoking (OR =1.750, 95% CI: 1.086-2.820, P=0.022), total chest pain time (OR =1.017, 95% CI: 1.000-1.035, P=0.049), recurrent acute chest pain (OR =2.750, 95% CI: 1.535-4.927, P=0.001), acute myocardial infarction (AMI) in the high lateral wall indicated by ECG (OR =5.527, 95% CI: 2.798-10.918, P<0.001), acute heart failure (OR =3.585, 95% CI: 2.074-6.195, P<0.001), and NT-proBNP level (OR =1.000, 95% CI: 1.000-1.000, P=0.023) were risk factors for CR in all patients. In patients who accepted PCI, single lesion (OR =0.421, 95% CI: 0.204-0.867, P=0.019), preoperative thrombolysis in myocardial infarction (TIMI) grade (OR =0.358, 95% CI: 0.169-0.760, P=0.007), and postoperative TIMI grade (OR =0.222, 95% CI: 0.090-0.546, P=0.001) were risk factors for CR. Conclusions: Non-single lesions and preoperative and postoperative TIMI grades were risk factors for CR in patients who accepted PCI. In addition to previously reported indicators, we found that AMI in the high lateral wall maybe helpful in early and accurate identification and prevention of possible CR.
RESUMO
The present study investigated whether the protective effect and mechanism of astragaloside IV (AS-IV) on heart failure (HF) involves small ubiquitin-like modifier (SUMO)-specific protease 1 (Senp1). Mouse HF was established by aortic constriction, inducing pressure overload. The model was confirmed by echocardiography 6 weeks after surgery. Mice were randomly divided into control, HF, HF+AS-IV, and AS-IV groups. Ventricular function was examined by echocardiography. Morphological changes of myocardial tissues were examined by H&E staining. The protein levels of the apoptosis-related proteins, cleaved caspase-3, caspase-3, Bcl2, Bax, and SUMO-Senp1 were determined by Western blotting. H2O2 in isolated mitochondria and cells was determined by Amplex Red. A reactive oxygen species (ROS) detection kit determined ROS levels in isolated mitochondria and HL-1 cells. JC-1 reagent measured mitochondrial membrane potential (ΔΨm). Apoptosis of HL-1 cells was examined by terminal deoxynucleotidyl transferase dUTP nick end labeling. Compared with the control group, the heart weight and heart mass/body weight ratio increased in the HF group (P<0.05). Furthermore, the ejection fraction and left ventricular shortening fraction decreased (P<0.05), while the left ventricular end-diastolic diameter (LVID;d) and end-systolic diameter (LVID;s) increased (P<0.05). Finally, mitochondrial ROS and H2O2 increased (P<0.05), while the ΔΨm decreased (P<0.05). However, AS-IV improved the cardiac function of HF mice, decreased the level of ROS and H2O2 in the myocardium, suppressed the decrease in ΔΨm, and decreased the apoptosis of myocardial cells (P<0.05). AS-IV also decreased the Senp1-overexpression. Furthermore, in HL-1 cells, Senp1-overexpression significantly inhibited the protective effects of AS-IV. AS-IV decreased oxidative stress in cardiomyocytes, decreased mitochondrial damage, inhibited ventricular remodeling, and ultimately improved cardiac function by inhibiting HF-induced Senp1-overexpression. This mechanism provides a novel theoretical basis and clinical treatment for HF.
RESUMO
OBJECTIVES: To compare the effectiveness and safety of the Braidin® slender 7 Fr sheath with a standard 6 Fr sheath for treating left main bifurcation disease. METHODS: From January 2017 to March 2019, 277 patients with left main bifurcation disease who underwent the transradial approach for percutaneous coronary intervention were divided into the slender 7 Fr sheath group (Braidin® slender 7 Fr sheath, n = 154) and standard 6 Fr sheath group (n = 123). Pathological features, surgical effect, and complications were evaluated. RESULTS: The rate of using the classic crush technique was significantly higher in the slender 7 Fr sheath group than in the standard 6 Fr sheath group. The slender 7 Fr sheath group had a significantly shorter operation time than the standard 6 Fr sheath group. There were no significant differences in the radial artery occlusion rate after surgery and at 1 month of follow-up between the groups. Multivariate logistic regression analysis showed that 6 Fr and Braidin slender 7 Fr sheaths did not predict radial artery occlusion. CONCLUSION: The Braidin slender 7 Fr sheath has a superior operative process and similar safety for the radial artery as that of the standard 6 Fr sheath for treating left main bifurcation disease.
