IJERPH, Vol. 17, Pages 731: Coronary Artery Disease Diagnosis; Ranking the Significant Features Using a Random Trees Model
In this study, we propose an integrated method using machine learning. The machine learning methods of random trees (RTs), decision tree of C5.0, support vector machine (SVM), and decision tree of Chi-squared automatic interaction detection (CHAID) are used in this study. The proposed method shows promising results and the study confirms that the RTs model outperforms other models.
Objective To investigate the association between non–high-density lipoprotein cholesterol/apolipoprotein A-I and monocyte/high-density lipoprotein cholesterol ratio and degree of coronary artery stenosis proven by coronary angiography. Methods A total of 1867 patients were enrolled into this study and analyzed retrospectively. Three hundred eighty-five non-coronary artery disease hospitalized patients were selected as control group, 1482 patients diagnosed as coronary artery disease were classified into three subgroups according to the tertiles of their SYNTAX score. We compared the level of non–high-densi...

Conclusion: The serum PDGF concentration in patients with acute coronary syndrome was significantly increased, especially in the local coronary artery. The serum Ang-1 in the coronary artery was significantly increased in patients with acute myocardial infarction and was related to the degree of coronary artery stenosis. Coronary sinus PDGF and Ang-1 levels can reflect the severity of lesions in patients with acute coronary syndrome. PMID: 32963822 [PubMed]
Conclusion: Through clinical research data, the study will help to provide guidance for the prevention and treatment of CHD angina pectoris complicated with diseases and promote further research.
CONCLUSION: Smoking cessation mitigates the increase in percent diameter stenosis of coronary non-target lesions, meanwhile, smokers are associated with increased risk for all-cause myocardial infarction compared with non-smokers. PMID: 32925280 [PubMed - as supplied by publisher]
Abstract Eosinophilic esophagitis (EoE) is an immune or antigen-mediated chronic inflammatory esophageal disorder that is relatively rare in Asian countries. The main symptoms of EoE are dysphagia and food impaction. Although chest pain is a symptom of EoE, it is also a symptom of coronary heart disease. This paper reports a case of EoE with angina pectoris in a 45-year-old male who was referred to the authors' hospital for chest pain. He was diagnosed with angina pectoris because of mild stenosis in the left coronary artery on coronary angiography. On the other hand, the symptoms did not improve with angina medic...
CONCLUSION: Nonagenarian patients are subject to more complications when undergoing coronary invasive procedures compared to patients under 75. PMID: 32800321 [PubMed - as supplied by publisher]
Conclusion: An elevated FFA level is an independent risk factor and independent diagnostic marker for AMI. PMID: 32648769 [PubMed - as supplied by publisher]
(Institute for Quality and Efficiency in Health Care) Non-invasive diagnostic procedures for suspected CHD: search reveals informative evidence Informative study results are available on diagnostic procedures using computed tomography angiography (CTA) and magnetic resonance imaging (MRI) for suspected coronary heart disease (CHD).
Abstract OBJECTIVE: To evaluate the value of epicardial adipose tissue (EAT) thickness combined with serum ischemic modified albumin (IMA) concentration in the diagnosis of coronary heart disease. METHODS: A total of 180 patients with coronary heart disease from May 2017 to December 2018 were selected as the case group. After the examination of Judkins coronary angiography, they were grouped according to the results of angiography, including 60 patients in a single-vessel group, 60 patients in a double-vessel group, and 60 patients in a multi-vessel group. Sixty healthy people with physical examinations at ou...
