Integrating the STOP-BANG score and clinical data to predict cardiovascular events after infarction: A machine learning study.

Integrating the STOP-BANG score and clinical data to predict cardiovascular events after infarction: A machine learning study. Chest. 2020 Apr 25;: Authors: Calvillo-Argüelles O, Sierra-Fernández CR, Padilla-Ibarra J, Rodriguez-Zanella H, Balderas-Muñoz K, Arias-Mendoza MA, Martínez-Sánchez C, Selmen-Chattaj S, Dominguez-Mendez BE, van der Harst P, Juarez-Orozco LE Abstract BACKGROUND: Obstructive sleep apnea (OSA) conveys worse clinical outcomes in coronary artery disease patients. The STOP-BANG score is a simple tool that evaluates the risk of OSA and can be added to the large number of clinical variables and scores obtained during the management of myocardial infarction (MI) patients. Currently, machine learning (ML) is able to select and integrate numerous variables to optimize prediction tasks. RESEARCH QUESTION: Can the integration of STOP-BANG score with clinical data and scores through ML better identify patients who suffered an in-hospital cardiovascular event after acute MI? STUDY DESIGN AND METHODS: This is a prospective observational cohort study of 124 acute MI patients in which the STOP-BANG score classified 34 low-(27.4%), 30 intermediate-(24.2%), and 60 high-(48.4%) OSA-risk patients who were followed during hospitalization. ML implemented feature selection and integration across 47 variables (including STOP-BANG score, Killip-class, GRACE score and LVEF) to identify those patients who developed ...

AbstractA new outpatient non-surgical method using Er:YAG laser for snoring has been demonstrated. The aim of this systematic review and meta-analysis was to investigate the effects of this treatment on snoring. Relevant 1548 articles were searched from various databases from 1 January 2000 to September 2018 including PubMed, MEDLINE, EMBASE, Cochrane Library, Web of Science, and Scopus and reference lists. Meta-analysis was performed with RevMan software. Cochran ’sQ andI2 statistics were used to assess heterogeneity. The overall effect was evaluated using z-tests. Seven studies and two hundred forty-seven participa...

CONCLUSIONS: Mandibular appliances are not a homogeneous entity. Common use includes only appliances designed for propulsion (with rods and jacks) and retention. However, the few comparative studies available do not identify which are the most effective types or the types with an optimal efficacy/tolerance ratio. PERSPECTIVES: Further appliance comparison studies are needed to determine the most effective type or with an optimal efficacy/tolerance ratio. PMID: 32636050 [PubMed - as supplied by publisher]

CONCLUSIONS: Extracting from the group of genes related to coronary atherosclerosis and cardiac failure: MMP-9, TGF-β1 and TIMP-1 differentiating patients with heart failure on the basis of myocardial ischemia in varying degrees of severity from healthy people may indicate their significant contribution to disease development. Also increased expression of the metalloproteinase gene 9 (MMP-9) with a simultaneous decrease in the expression of its tissue inhibitor 1 (TIMP-1) in the studied group of patients with ischemic heart failure differing in left ventricular ejection fraction (LVEF) makes them the markers of progre...

Authors: Stepien K, Furczynska P, Zalewska M, Nowak K, Wlodarczyk A, Owsianka I, Skorek P, Zalewski J, Nessler J Abstract BACKGROUND: Recently heart failure (HF) has been found to be a new dementia risk factor, nevertheless their relations in patients following HF decompensation remain unknown. We sought to investigate whether a screening diagnosis for dementia (SDD) in this high-risk population may predict unfavorable long-term clinical outcomes. METHODS: 142 patients following HF decompensation requiring hospitalization were enrolled. Within a median time of 55 months all patients were screened for dementia w...

Authors: Ueno H, Imamura T, Kinugawa K Abstract Patients with advanced heart failure often accompany severe function mitral regurgitation refractory to optimal medical therapy. Degenerative mitral regurgitation also develops due to various degeneration of mitral valve. Surgical intervention to the mitral valve might be effective in some cases, but it is challenging for the high-risk cases. Recently, percutaneous edge-to-edge mitral valve repair using the MitraClip system, which enables us to approach the mitral valve at relatively low risk, has developed. Two major prospective randomized control trials have been co...

Authors: Su W, Wang M, Zhu J, Li W, Ding X, Chen H, Li HW, Zhao XQ Abstract Increased body mass index (BMI) is a well-established risk factor for cardiovascular disease; however, patients with elevated BMI, in comparison to those with low BMI, seem to have better survival, a phenomenon reported as "obesity paradox," which remains controversial. We investigated the effect of BMI on cardiac mortality post acute myocardial infarction (AMI).In this analysis, 3562 AMI patients were included and classified into four groups based on BMI values. The primary endpoint was cardiac death. Compared to normoweight grou...
