Although left ventricular ejection fraction (LVEF) is commonly used, and identifies patients with poor systolic function, other easily acquired measures of cardiac function are needed, particularly to stratify patients with relatively preserved LVEF. LV relative wall thickness (RWT) has been associated with adverse clinical outcomes in patients with preserved LVEF, but the clinical relevance of this observation is not known. The purpose of this study was to assess whether increased RWT is a marker of subclinical cardiac dysfunction as measured by a surrogate of LV dysfunction and left ventricular ejection time (LVET) and if increased RWT is independently associated with chronic kidney disease (CKD), an important clinical outcome and cardiovascular disease risk equivalent.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This retrospective cohort study enrolled ambulatory patients 18 years and older undergoing routine transthoracic echocardiography (TTE) at Johns Hopkins Hospital from January 2017 to January 2018. Patients with LVEF &lt;50%, severe valvular disease, or liver failure were excluded. Multivariable regression evaluated the relationship between RWT, LVET, and CKD adjusted for demographics, comorbidities, and vital signs.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;We analyzed data from 375 patients with mean age (±SD) 52.2 ± 15.3 years of whom 58% were female. Mean ± SD of RWT was 0.45 ± 0.10, while mean ± SD of LVET was 270 ms ± 33. In multivariable linear regression adjusted for demographics, comorbidities, vital signs, and left ventricular mass, each 0.1 increase in RWT was associated with a decrease of 4.6 ms in LVET, indicating worse cardiac function (β, ± 95% CI) (-4.60, -7.37 to -1.48, p = 0.004). Of those with serum creatinine available 1 month before or after TTE, 20% (50/247) had stage 3 or greater CKD. In logistic regression (adjusted for sex, comorbidities, and medications), each 0.1 unit increase in RWT was associated with an 61% increased odds of CKD (aOR = 1.61, 1.03-2.53, p = 0.037). In multivariable ordinal regression adjusted for the same covariates, each 0.1 unit increase in RWT was associated with a 44% increased odds of higher CKD stage (aOR = 1.44, 1.03-2.02, p = 0.035). There was a trend but no statistically significant relationship between RWT and change in estimated glomerular filtration rate at 1 year.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;In an outpatient cohort undergoing TTE, increased RWT was independently associated with a surrogate of subclinical systolic dysfunction (LVET) and CKD.

However, the causal connection between the two conditions is uncertain. We aimed to investigate the causal association of OSA with HF and its risk factors.METHODSThe OSA summary statistics are derived from the FinnGen database, including 38,998 cases and 336,659 controls. and HF summary statistics come from HERMES, the UK biobank, and the FinnGen database. A two-sample Mendelian randomization (MR) analysis was conducted to examine the causality of OSA on HF risk. Furthermore, the mediator effect of potential risk factors was assessed by a two-step MR.RESULTSThe results of MR analysis demonstrated that genetically determined OSA is causal associated with the higher likelihood of HF (HERME: odds ratio [OR] = 1.222; 95% confidence interval [CI] [1.091, 1.369]; p = 5.19 × 10-4) (FinnGen: OR = 1.233; 95% CI [1.129, 1.346]; p = 3.32 × 10-6) (UK Biobank: OR = 1.002; 95% CI [1.000, 1.003]; p = 0.014). Two-step MR analysis indicated that obesity, blood glucose, depression, and other CVDs have significant mediating effects on the causal effect between OSA and HF.CONCLUSIONThis MR study emphasizes the causal effect of OSA on HF risk. Adiposity traits play a major role in the process of OSA leading to HF. Considering the detrimental impact of OSA on HF, it becomes imperative to prioritize the prevention and management of HF in individuals afflicted with OSA. The foremost intervention strategy should revolve around effective obesity management.","PeriodicalId":9391,"journal":{"name":"Cardiology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142258244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
