{"title":"Development and Validation of Nomograms for predicting Coronary Artery Calcification and Severe Coronary Artery Calcification: a retrospective cross-sectional study","authors":"Peng Xue, Ling Lin, Peishan Li, Zhengting Deng, Xiaohu Chen, Yanshuang Zhuang","doi":"10.1101/2024.09.12.24313598","DOIUrl":"https://doi.org/10.1101/2024.09.12.24313598","url":null,"abstract":"Background: There is a significant lack of effective pharmaceutical interventions for treating coronary artery calcification (CAC). Severe CAC (sCAC) poses a formidable challenge to interventional surgery and exhibits robust associations with adverse cardiovascular outcomes. Therefore, it is imperative to develop tools capable of early-stage detection and risk assessment for both CAC and sCAC. This study aims to develop and validate nomograms for the accurate prediction of CAC and sCAC. Methods: This retrospective cross-sectional study was conducted in Taizhou, Jiangsu Province, China. CAC assessment was performed using non-gated thoracic CT scans. Demographic data and clinical information were collected from patients who were then randomly divided into a training set (70%) or a validation set (30%). Least absolute shrinkage and selection operator (LASSO) regression as well as multiple logistic regression analyses were utilized to identify predictive factors for both CAC and sCAC development. Nomograms were developed to predict the occurrence of CAC or sCAC events. The models' performance was evaluated through discrimination analysis, calibration analysis, as well as assessment of their clinical utility. Results: This study included 666 patients with an average age of 75 years, of whom 56% were male. 391 patients had CAC, with sCAC in 134 cases. Through LASSO and multiple logistic regression analysis, age increase, hypertension, carotid artery calcification, CHD, and CHADS2 score were identified for the CAC risk predictive nomogram with an area under the receiver operating characteristic (ROC) curve (AUC) of 0.845(95%CI 0.809-0.881) in the training set and 0.810(95%CI 0.751-0.870) in the validation set. Serum calcium level, carotid artery calcification, and CHD were identified for the sCAC risk predictive nomogram with an AUC of 0.863(95%CI 0.825-0.901) in the training set and 0.817(95%CI 0.744-0.890) in the validation set. Calibration plots indicated that two models exhibited good calibration ability. According to the decision curve analysis (DCA) results, both models have demonstrated a positive net benefit within a wide range of risks. Conclusions: The present study has successfully developed and validated two nomograms to accurately predict CAC and sCAC, both of which have demonstrated robust predictive capabilities.","PeriodicalId":501297,"journal":{"name":"medRxiv - Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142258374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Left ventricular concentric remodeling (LVCR) is a pathological process of adaptive myocardial change that may represent a precursor state for systolic and diastolic dysfunction and left ventricular hypertrophy. Given that potentially cardiotoxic airborne hazards, such as those produced by open burn pits, have been found to occur in excess in active military combat zones, deployed veterans may be at increased risk for adverse cardiac remodeling, but this has not been thoroughly investigated.\u0000Methods:\u0000139 veterans of Southwest Asia Theater of Military Operations underwent transthoracic echocardiography, cardiopulmonary exercise testing (CPET), and health questionnaires. Two-dimensional echocardiography was used to quantify relative wall thickness (RWT) to classify left ventricular (LV) geometry as normal, concentric/eccentric hypertrophy, or LVCR. Observed rates of LVCR were compared to those reported in the Framingham Heart Study, and CPET results were compared between those with and without LVCR. We examined the association between RWT and select CPET outcomes via an adjusted multivariate regression model.\u0000Results:\u0000The prevalence of LVCR in the veteran sample (30.2%) was elevated compared to the Framingham Heart Study cohort (6-16%). Demographics and risk factors were similar between veterans with LVCR and normal geometry; however, veterans with LVCR had reduced exercise capacity (VO2, 23.7 vs 26.2 ml/kg/min, p<0.05), more inefficient exercise ventilation (VE/V?CO2 nadir: 26.8 vs 25.2, p<0.05), and increased heart rate (HR) reserve (24.7 vs 17.4, p<0.05). RWT was independently associated only with peak HR attained and HR reserve. Conclusions:\u0000In our sample of deployed veterans without significant risk factors, the observed rates of LVCR are 2- to 5-fold greater than those reported in a historical civilian cohort. Further, veterans with LVCR also had impaired exercise performance relative to those with normal LV geometry despite otherwise appearing similar. These findings underscore the importance of cardiovascular assessments as part of a dyspnea evaluation for deployed veterans with airborne hazards exposure and raise concerns about their long-term cardiovascular health.","PeriodicalId":501297,"journal":{"name":"medRxiv - Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142218923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This is a prospective-analytical epidemiological study, of a quantitative nature, carried out on 226 employees, in two stages: collection of self-declared data and measurement of anthropometric data. Results: Risk factors such as family history of CVD (82.7%), alcoholism (57.1%), sedentary lifestyle (49.1%), insufficient sleep time (27.9%), high consumption of processed meals (98.2%) and sugary beverages (81.7%) were observed, among others. From anthropometric data, it was identified that 69.4% of participants are overweight (38.7%) or obese (30.6%) - evidenced by high waist circumference (48.6%) and a high waist-to-hip ratio (64.0%) - in addition to 17.1% who had blood pressure levels indicative of arterial hypertension. The majority reported not having a diagnosis of CVDs (76.1%), however, among those who do, more than half (53.7%) do not treat them properly. Conclusion: It is observed that the prevalence of CVDs is not irrelevant in the group evaluated and that there is the presence of risk factors indicating a tendency for participants to develop new CVDs or worsen existing ones, due to the presence of harmful habits associated with an unhealthy lifestyle and lack of adherence to treatments. This study suggests the implementation of multidisciplinary action programs with employees, so that the main areas identified as deficient are addressed.","PeriodicalId":501297,"journal":{"name":"medRxiv - Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142218966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of this study were: 1) to describe population trends for outcomes, risk factors, and medication prescribing patterns post-ACS and 2) to identify factors associated with recurrent MACE.\u0000Methods: A retrospective cohort study of 4,884 post-ACS patients admitted at a large integrated healthcare system between 2015-2021 was performed to investigate the relationship between recurrent MACE (ACS, cerebrovascular events, all-cause mortality, and unplanned revascularization), modifiable risk factor trends, and medical therapy prescribing patterns. Patients were separated into 2 cohorts based upon whether they experienced recurrent MACE following the initial hospitalization. Data were obtained via programmatic extraction from the electronic health record. Descriptive statistics were performed. Generalized linear models were used to assess risk factor trends and pairwise comparisons were performed between time points. Results: Median length of follow-up after ACS was 31.2 months. Recurrent MACE occurred in 28% of patients. Despite 95.9% of all patients receiving prescriptions for high-intensity statins, >40% did not achieve LDL-C goal of <70 mg/dL, and only 11.6% and 2.6% of all patients were prescribed ezetimibe or proprotein convertase subtilisin kexin type 9 inhibiting monoclonal antibodies, respectively. Although >30.0% of patients had triglycerides ≥150 mg/dL at all time points, ≤6% were prescribed any non-statin triglyceride lowering therapy and 0.6% were prescribed icosapent ethyl. Persistent hypertriglyceridemia (≥150 mg/dL) was associated with recurrent MACE at 6-, 12-, and 24-months post-ACS (p<0.05), and the relative risk ranged between 1.20-1.35 at those timepoints. Conclusions: This study demonstrates the need for more comprehensive post-ACS care to address residual cardiometabolic risk factors and suboptimal prescribing patterns for indicated therapies. Targeted strategies are needed to address hypertriglyceridemia for cardiovascular risk reduction.","PeriodicalId":501297,"journal":{"name":"medRxiv - Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142218924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its roles in the occurrence and progression of acute coronary syndrome (ACS) following COVID-19 infection has not been fully studied.\u0000Methods: Firstly, we used the 5hmC-Seal technique to obtain genome-wide 5hmC profiles from plasma cfDNA of 24 ACS2N patients (individuals experiencing ACS onset within 2 months after COVID-19 infection), 28 ACS2W patients (individuals experiencing ACS onset beyond 2 months after COVID-19 infection), and 16 ACS patients (patients with ACS without COVID-19 infection). Secondly, we performed GO, KEGG analysis on the differentially expressed genes and identified a series of immune and inflammation related genes. Thirdly, the distribution of immune cells in different groups of patients was studied by immune infiltration analysis. Finally, we performed PPI network analysis on these genes to identify potential key target genes.\u0000Results: In this study, we firstly found that there was a significant difference in 5hmC levels between ACS2N patients and ACS patients, while the difference between ACS2W and ACS was not significant. Secondly, it was found that neutrophils were abnormally activated in the ACS2N group. Finally, a target gene phosphodiesterase 4D (PDE4D) was found to be highly expressed in the ACS2N group by PPI network analysis of the differential genes and validated with external datasets.\u0000Conclusions: Our study suggested that 5hmC markers extracted from plasma cfDNA could differentiate between ACS2N and ACS patients. In addition, we observed that neutrophils exhibited abnormal activation in ACS2N patients. Further analysis showed that COVID-19 infection may affect the occurrence and development of ACS by abnormally up-regulating PDE4D gene expression.","PeriodicalId":501297,"journal":{"name":"medRxiv - Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142218925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to explore the acceptability of WAterS from the stroke survivors perspective. Semi structured interviews were conducted with twelve stroke survivors who received WAterS. The interview schedule was informed by theorised components of acceptability, including understanding, burden and perception of effectiveness. The data were analysed inductively and deductively using Template Analysis. Six qualitative themes were generated. Results indicate the intervention was mostly understandable and participants were able to engage with ACT and apply it to life. Online delivery reduced burden in accessing the intervention, and was acceptable when supported by live facilitation and a physical handbook. Group cohesion and understanding was facilitated by practitioners. The social aspect of the group was beneficial. Attending WAterS supported some participants to seek further support; others were left feeling unsupported when the intervention ended. To conclude: Stroke survivors valued attending an online, group ACT informed intervention, delivered by practitioners.
