Opportunities and challenges for artificial intelligence in clinical cardiovascular genetics.

A combination of emerging genomic and artificial intelligence (AI) techniques may ultimately unlock a deeper understanding of heterogeneity and biological complexities in cardiovascular diseases (CVDs), leading to advances in prognostic guidance and personalized therapies. We discuss the state of AI in cardiovascular genetics, current applications, limitations, and future directions of the field.

Management of patients with heart failure and chronic kidney disease.

Chronic kidney disease (CKD) and heart failure are often co-existing conditions due to a shared pathophysiological process involving neurohormonal activation and hemodynamic maladaptation. A wide range of pharmaceutical and interventional tools are available to patients with CKD, consisting of traditional ones with decades of experience and newer emerging therapies that are rapidly reshaping the landscape of medical care for this population. Management of patients with heart failure and CKD requires a stepwise approach based on renal function and the clinical phenotype of heart failure. This is often challenging due to altered drug pharmacokinetics interactions with various degrees of kidney function and frequent adverse effects from the therapy that lead to poor patient tolerance. Despite a great body of clinical evidence and guidelines that have offered various treatment options for patients with heart failure and CKD, respectively, patients with CKD are still underrepresented in heart failure clinical trials, especially for those with advanced CKD and end-stage renal disease (ESRD). Future studies are needed to better understand the generalizability of these therapeutic options among heart failures with different stages of CKD.

Spontaneous Coronary Artery Dissection with Cardiogenic Shock in the United States.

Background: Spontaneous coronary artery dissection (SCAD) is defined as a non-traumatic separation of the epicardial coronary artery walls that creates a false lumen. SCAD poses a difficult challenge in management, as decisions regarding revascularization and medical management seem to be tailored to the individual patient. We evaluated and compared outcomes based on cardiogenic shock in patients with SCAD utilizing Nationwide Readmissions Database (NRD) between January 1, 2016, to December 30, 2020. Methods: We utilized the NRD 2016-2019 to carry out this study. We evaluated demographics (e.g., age, gender), conventional risk factors, comorbidities present on the index admission, and in-hospital outcomes using their specific ICD-10-CM codes. The primary outcomes were In-hospital mortality and 30-day readmission, and the secondary outcome was to compare the complications in SCAD patient with cardiogenic shock (CS) compared to those without CS. Results: We analyzed 2473 individuals with SCAD, 2199 of these individuals did not have cardiogenic shock whereas 274 of these individuals did have cardiogenic shock. When comparing SCAD with cardiogenic shock to SCAD without cardiogenic shock, there was a statistically significant increased odds ratio (OR) for death (propensity matched OR 24.93 (7.49-83.05), use of mechanical circulatory support (propensity matched OR 15.30 (6.87-34.04), ventricular tachycardia (propensity matched OR 4.45 (1.92-10.34), utilization of blood transfusions (propensity matched OR 3.82 (1.86-7.87), acute kidney injury (propensity matched OR 4.02 (1.45-11.13), need for mechanical ventilation (propensity matched OR 8.87 (3.53-22.31), and respiratory failure (propensity matched OR 4.95 (1.83-13.41)))))))). There was no statistically significant difference in 30-day readmission rates between the two groups. Conclusions: SCAD is a unique condition that can lead to many complications. In our analysis, we showed that SCAD associated with cardiogenic shock compared to SCAD not associated with cardiogenic shock results in greater odds of complications including death, use of mechanical circulatory support, need for blood transfusions, ventricular tachycardia, acute kidney injury, use of mechanical ventilation, and respiratory failure. SCAD with cardiogenic shock represents a significantly critical clinical scenario that requires a multi-disciplinary approach to prevent the many potential complications associated with this disease process.

Left Main Coronary Artery Disease: A Contemporary Review of Diagnosis and Management.

Significant left main coronary artery disease is a very high-risk subgroup of coronary artery disease that is a crucial indicator of heightened morbidity and mortality rates. Despite its clinical significance, uncertainties persist regarding the optimal management strategy for patients, particularly given its phenotypic variations. Existing evidence-based guidelines offer insights into revascularization options, yet questions remain regarding long-term prognoses and clinical outcomes when comparing percutaneous coronary intervention to coronary artery bypass grafting. This comprehensive review aims to provide an in-depth analysis of contemporary strategies for the diagnosis, assessment, and treatment of left main coronary artery disease. By synthesizing current literature and addressing the evolving landscape of revascularization modalities, this review seeks to contribute valuable insights for clinicians and researchers grappling with the complexities of managing left main coronary artery disease.

Pharmacotherapy for Coronary Artery Disease and Acute Coronary Syndrome in the Aging Population.

PURPOSE OF REVIEW: To provide a comprehensive summary of relevant studies and evidence concerning the utilization of different pharmacotherapeutic and revascularization strategies in managing coronary artery disease and acute coronary syndrome specifically in the older adult population. RECENT FINDINGS: Approximately 30% to 40% of hospitalized patients with acute coronary syndrome are older adults, among whom the majority of cardiovascular-related deaths occur. When compared to younger patients, these individuals generally experience inferior clinical outcomes. Most clinical trials assessing the efficacy and safety of various therapeutics have primarily enrolled patients under the age of 75, in addition to excluding those with geriatric complexities. In this review, we emphasize the need for a personalized and comprehensive approach to pharmacotherapy for coronary heart disease and acute coronary syndrome in older adults, considering concomitant geriatric syndromes and age-related factors to optimize treatment outcomes while minimizing potential risks and complications. In the realm of clinical practice, cardiovascular and geriatric risks are closely intertwined, with both being significant factors in determining treatments aimed at reducing negative outcomes and attaining health conditions most valued by older adults.

Efficacy of Diagnostic Testing of Suspected Coronary Artery Disease: A Contemporary Review.

BACKGROUND: Coronary artery disease (CAD) is a highly prevalent condition which can lead to myocardial ischemia as well as acute coronary syndrome. Early diagnosis of CAD can improve patient outcomes through guiding risk factor modification and treatment modalities. SUMMARY: Testing for CAD comes with increased cost and risk; therefore, physicians must determine which patients require testing, and what testing modality will offer the most useful data to diagnose patients with CAD. Patients should have an initial risk stratification for pretest probability of CAD based on symptoms and available clinical data. Patients with a pretest probability less than 5% should receive no further testing, while patients with a high pretest probability should be considered for direct invasive coronary angiography. In patients with a pretest probability between 5 and 15%, coronary artery calcium score and or exercise electrocardiogram can be obtained to further risk stratify patients to low-risk versus intermediate-high-risk. Intermediate-high-risk patients should be tested with coronary computed tomography angiography (preferred) versus positron emission tomography or single photon emission computed tomography based on their individual patient characteristics and institutional availability. KEY MESSAGES: This comprehensive review aimed to describe the available CAD testing modalities, detail their risks and benefits, and propose when each should be considered in the evaluation of a patient with suspected CAD.

The Current State of Coronary Revascularization: Coronary Artery Bypass Graft Surgery Versus Percutaneous Coronary Interventions.

PURPOSE OF REVIEW: The optimal revascularization strategy for coronary artery disease depends on various factors, such as disease complexity, patient characteristics, and preferences. Including a heart team in complex cases is crucial to ensure optimal outcomes. Decision-making between percutaneous coronary intervention and coronary artery bypass grafting must consider each patient's clinical profile and coronary anatomy. While current practice guidelines offer some insight into the optimal revascularization approach for the various phenotypes of coronary artery disease, the evidence to support either strategy continues to evolve and grow. Given the large amount of contemporary data on revascularization, this review aims to comprehensively summarize the literature on coronary artery bypass grafting and percutaneous coronary intervention in patients across the spectrum of coronary artery disease phenotypes. RECENT FINDINGS: Contemporary evidence suggests that for patients with triple vessel disease, coronary artery bypass grafting is preferred over percutaneous coronary intervention due to better long-term outcomes, including lower rates of death, myocardial infarction, and target vessel revascularization. Similarly, for patients with left main coronary artery disease, both percutaneous coronary intervention and coronary artery bypass grafting can be considered, as they have shown similar efficacy in terms of major adverse cardiac events, but there may be a slightly higher risk of death with percutaneous coronary intervention. For proximal left anterior descending artery disease, both percutaneous coronary intervention and coronary artery bypass grafting are viable options, but coronary artery bypass grafting has shown lower rates of repeat revascularization and better relief from angina. The Synergy Between PCI with Taxus and Cardiac Surgery score can help in decision-making by predicting the risk of adverse events and guiding the choice between percutaneous coronary intervention and coronary artery bypass grafting. European and American guidelines both agree with including a heart team that can develop and lay out individualized, optimal treatment options with respect for patient preferences. The debate between coronary artery bypass grafting versus percutaneous coronary intervention in multiple different scenarios will continue to develop as technology and techniques improve for both procedures. Risk factors, pre, peri, and post-procedural complications involved in both revascularization strategies will continue to be mitigated to optimize outcomes for those patients for which coronary artery bypass grafting or percutaneous coronary intervention provide ultimate benefit. Methods to avoid unnecessary revascularization continue to develop as well as percutaneous technology that may allow patients to avoid surgical intervention when possible. With such changes, revascularization guidelines for specific patient populations may change in the coming years, which can serve as a limitation of this time-dated review.

Clinical Update in Heart Failure with Preserved Ejection Fraction.

PURPOSE OF REVIEW: To review the most recent clinical trials and data regarding epidemiology, pathophysiology, diagnosis, and treatment of heart failure with preserved ejection fraction with an emphasis on the recent trends in cardiometabolic interventions. RECENT FINDINGS: Heart failure with preserved ejection fraction makes up approximately half of overall heart failure and is associated with significant morbidity, mortality, and overall burden on the healthcare system. It is a complex, heterogenous syndrome and clinical trials, to this point, have not revealed quite as many effective treatment options when compared to heart failure with reduced ejection fraction. Nevertheless, there is an expanding amount of data insight into the pathogenesis of this disease and the potential for newer therapies and management strategies. Heart failure with preserved ejection fraction pathology has been found to be linked to abnormal energetics, myocyte hypertrophy, cell signaling, inflammation, ischemia, and fibrosis. These mechanisms also intricately overlap with the significant comorbidities often associated with heart failure with preserved ejection fraction including, but not limited to, atrial fibrillation, chronic kidney disease, hypertension, obesity and coronary artery disease. Treatment of this disease, therefore, should focus on the management and strict regulation of these comorbidities by pharmacologic and nonpharmacologic means. In this review, a clinical update is provided reviewing the most recent clinical trials and data regarding epidemiology, pathophysiology, diagnosis, and treatment of heart failure with preserved ejection fraction with an emphasis on the recent trend in cardiometabolic interventions.

Artificial Intelligence, specifically advanced language models such as ChatGPT, have the potential to revolutionize various aspects of healthcare, medical education, and research. In this narrative review, we evaluate the myriad applications of ChatGPT in diverse healthcare domains. We discuss its potential role in clinical decision-making, exploring how it can assist physicians by providing rapid, data-driven insights for diagnosis and treatment. We review the benefits of ChatGPT in personalized patient care, particularly in geriatric care, medication management, weight loss and nutrition, and physical activity guidance. We further delve into its potential to enhance medical research, through the analysis of large datasets, and the development of novel methodologies. In the realm of medical education, we investigate the utility of ChatGPT as an information retrieval tool and personalized learning resource for medical students and professionals. There are numerous promising applications of ChatGPT that will likely induce paradigm shifts in healthcare practice, education, and research. The use of ChatGPT may come with several benefits in areas such as clinical decision making, geriatric care, medication management, weight loss and nutrition, physical fitness, scientific research, and medical education. Nevertheless, it is important to note that issues surrounding ethics, data privacy, transparency, inaccuracy, and inadequacy persist. Prior to widespread use in medicine, it is imperative to objectively evaluate the impact of ChatGPT in a real-world setting using a risk-based approach.

Highlights of Cardiovascular Disease Prevention Studies Presented at the 2023 American College of Cardiology Conference.

PURPOSE OF REVIEW: To summarize selected late-breaking science on cardiovascular (CV) disease prevention presented at the 2023 American College of Cardiology (ACC) conference. RECENT FINDINGS: The CLEAR outcomes randomized control trial (RCT) compared bempedoic acid to placebo in patients at high-risk of cardiovascular disease (CVD) or prevalent CVD and statin intolerance for CV outcomes. The YELLOW III was a single-arm study that evaluated the effect of Evolocumab on coronary plaque characteristics in patients with stable coronary artery disease (CAD). A cohort evaluated the association between a self-reported low-carbohydrate high-fat (ketogenic) diet and serum lipid levels as compared to a standard diet. The LOADSTAR trial compared CV outcomes with targeted low-density lipoprotein cholesterol (LDL-C) approach vs. high-intensity statin in patients with CAD. The PCDS statin cluster randomized trial compared the effectiveness of an electronic reminder to the clinician on a high-intensity statin use among patients with a history of ASCVD as compared to no reminder. A prospective cohort study compared the extent of coronary atherosclerosis among lifelong endurance athletes and healthy non-athletes. A causal artificial intelligence study combined polygenic risk scores with data from large CV prevention RCTs to guide systolic blood pressure and LDL-C reduction targets to reach average CV risk. The ACCESS trial evaluated the impact of eliminating copayment for low-income older adults in Canada with chronic CV diseases on composite CV outcomes. A pooled analysis of 3 large RCTs evaluated the association between residual inflammatory risk and CV outcomes, as compared to residual elevated cholesterol risk in patients receiving statin therapy. A Phase 2B RCT compared the efficacy of an oral PCSK9i, MK-0616, in reducing LDL-C as compared to a placebo. The late-breaking clinical science presented at the 2023 conference of the ACC paves the way for an evidence-based alternative to statin therapy and provides data on several common clinical scenarios encountered in daily practice.

The Clinical Efficacy and Safety of Bempedoic Acid in Patients at Elevated Risk of Cardiovascular Disease: A Meta-Analysis of Randomized Clinical Trials.

PURPOSE: Statins are first-line agents to reduce low-density lipoprotein cholesterol (LDL-C) and cardiovascular risk, however, they are insufficient and/or intolerable in many patients. To that end, we conducted a meta-analysis of Bempedoic Acid (BA), a novel LDL-C lowering agent. METHODS: We retrieved randomized clinical trials (RCTs) of BA by searching Pubmed, the Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov. We used the Mantel-Haenszel method to pool estimates. The I2 measure was used to quantify heterogeneity. Treatment effects are provided as relative risks (RR), absolute risk differences (ARD), and number needed to treat/harm (NNTB/H). Analyses were conducted using R, version 4.1.2. RESULTS: 11 trials enrolling 18,496 patients were included. Compared to placebo, BA reduced the risk of major adverse cardiovascular events (RR: 0.87; 95% CI: 0.80 to 0.95; ARD: -1.63%; NNT: 62), myocardial infarction (RR: 0.76; 95% CI: 0.66 to 0.89; ARD: -1.03%; NNT: 98), unstable angina hospitalization (RR: 0.70; 95%: CI: 0.55 to 0.89; ARD: -0.57%; NNT: 177), revascularization (RR: 0.81; 95% CI: 0.72 to 0.91; ARD: -1.31%; NNT: 77), and myalgia (RR: 0.85; 95% CI: 0.75 to 0.95; ARD: -0.99%; NNT: 102). BA significantly increased the risk of gout (RR: 1.56; 95% CI: 1.27 to 1.91; ARD: 0.99%; NNH: 101), renal impairment (RR: 1.35; 95% CI: 1.22 to 1.49; ARD: 2.54%; NNH: 40), and cholelithiasis (RR: 1.87; 95% CI: 1.43 to 2.44; ARD: 1.01%; NNH: 100). CONCLUSION: BA effectively reduces the risk of cardiovascular events and myalgia but increases the risk of gout, cholelithiasis, and renal impairment.

Celiac Disease and the Risk of Cardiovascular Diseases.

Celiac disease (CD) is a chronic autoimmune disorder that affects the small intestine in genetically predisposed individuals. Previous studies have investigated the potential link between CD and cardiovascular disease (CVD); however, the findings have been inconsistent. We aimed to provide an updated review of the literature on the association between CD and CVD. PubMed was searched from inception to January 2023 using keywords including CD, cardiovascular disease, coronary artery disease, cardiac arrhythmia, heart failure, cardiomyopathy, and myocarditis. We summarized the results of the studies, including meta-analyses and original investigations, and presented them according to the different forms of CVD. Meta-analyses published in 2015 provided mixed results regarding the relationship between CD and CVD. However, subsequent original investigations have shed new light on this association. Recent studies indicate that individuals with CD are at a higher risk of developing overall CVD, including an increased risk of myocardial infarction and atrial fibrillation. However, the link between CD and stroke is less established. Further research is needed to determine the link between CD and other cardiac arrhythmias, such as ventricular arrhythmia. Moreover, the relationship between CD and cardiomyopathy or heart failure, as well as myopericarditis, remains ambiguous. CD patients have a lower prevalence of traditional cardiac risk factors, such as smoking, hypertension, hyperlipidemia, and obesity. Therefore, it is important to discover strategies to identify patients at risk and reduce the risk of CVD in CD populations. Lastly, it is unclear whether adherence to a gluten-free diet can diminish or increase the risk of CVD among individuals with CD, necessitating further research in this area. To fully comprehend the correlation between CD and CVD and to determine the optimal prevention strategies for CVD in individuals with CD, additional research is necessary.

NAFLD in Cardiovascular Diseases: A Contributor or Comorbidity?

Nonalcoholic fatty liver disease (NAFLD) and cardiovascular diseases are both highly prevalent conditions around the world, and emerging data have shown an association between them. This review found several longitudinal and cross-sectional studies showing that NAFLD was associated with coronary artery disease, cardiac remodeling, aortic valve remodeling, mitral annulus valve calcifications, diabetic cardiomyopathy, diastolic cardiac dysfunction, arrhythmias, and stroke. Although the specific underlying mechanisms are not clear, many hypotheses have been suggested, including that metabolic syndrome might act as an upstream metabolic defect, leading to end-organ manifestations in both the heart and liver. Management of NAFLD includes weight loss through lifestyle interventions or bariatric surgery, and pharmacological interventions, often targeting comorbidities. Although there are no Food and Drug Administration-approved nonalcoholic steatohepatitis-specific therapies, several drug candidates have demonstrated effect in the improvement in fibrosis or nonalcoholic steatohepatitis resolution. Further studies are needed to assess the effect of those interventions on cardiovascular outcomes, the major cause of mortality in patients with NAFLD. In conclusion, a more comprehensive, multidisciplinary approach to diagnosis and management of patients with NAFLD and cardiovascular diseases is needed to optimize clinical outcomes.

Correlates of SGLT-2-inhibitiors use among patients with atherosclerotic cardiovascular disease and type 2 diabetes mellitus: Insights from the department of veterans affairs.

This study using data from the Veterans Affairs (VA) administrative and clinical dataset examined determinants of sodium-glucose cotransporter-2 inhibitors (SGLT-2i) use among patients with concomitant atherosclerotic cardiovascular disease (ASCVD) and diabetes mellitus. The aim of the present analysis was to identify barriers and facilitators associated with SGLT-2i in a real-world contemporary patient population in order to improve utilization of these guideline-directed agents.

Outcomes of rotational atherectomy followed by cutting balloon versus plain balloon before drug-eluting stent implantation for calcified coronary lesions: A meta-analysis.

OBJECTIVE: The aim of this study is to compare outcomes of rotational atherectomy and cutting balloon (RACB) versus rotational atherectomy and plain balloon (RAPB) before drug-eluting stent (DES) implantation in calcified coronary lesions. METHODS: Randomized controlled trials (RCT) and observational studies comparing RACB with RAPB were identified through a systematic search of published literature across multiple databases. Random effect meta-analysis was performed to compare the outcome between the two groups. RESULTS: Four studies were included in the meta-analysis (three observational and one RCT) involving a total of 315 patients. 166 patients had RACB, and 149 patients had RAPB before DES placement with a median follow-up of 11.5 months. Compared with patients who had RAPB there was no difference in MACE (composite of death, myocardial infarction, and target vessel revascularization) (odds ratio [OR]: 0.74; 95% confidence interval [CI]: 0.25-2.18], slow flow/no reflow (OR: 0.71; 95% CI: 0.23-2.16), all-cause mortality (OR: 2.02; 95% CI: 0.28-14.60), and device success rate (OR: 1.79; 95% CI: 0.28-11.18) in the RACB approach. There was a benefit towards less target lesion revascularization in the RACB group; however, this outcome was reported in two studies (OR: 0.29; 95% CI: 0.08-0.99). On meta-regression there was no association between age, sex, diabetes, or lesion location with MACE and all-cause mortality. The studies were homogenous across all outcomes. CONCLUSION: RACB, as compared with RAPB, had a similar risk of MACE, all-cause mortality, device success, and complication, but a lower risk of target lesion revascularization.

Significant Facility-Level Variation in Utilization of and Adherence with Secondary Prevention Therapies Among Patients with Premature Atherosclerotic Cardiovascular Disease: Insights from the VITAL (Veterans wIth premaTure AtheroscLerosis) Registry7.

PURPOSE: We investigated facility-level variation in the use and adherence with antiplatelets and statins among patients with premature and extremely premature ASCVD. METHODS: Using the 2014-2015 nationwide Veterans wIth premaTure AtheroscLerosis (VITAL) registry, we assessed patients with premature (age at first ASCVD event: males < 55 years, females < 65 years) and extremely premature ASCVD (< 40 years). We examined frequency and facility-level variation in any statin, high-intensity statin (HIS), antiplatelet use (aspirin, clopidogrel, ticagrelor, prasugrel, and ticlopidine), and statin adherence (proportion of days covered ≥ 0.8) across 130 nationwide VA healthcare facilities. Facility-level variation was computed using median rate ratios (MRR), a measure of likelihood that two random facilities differ in use of statins or antiplatelets and statin adherence. RESULTS: Our analysis included 135,703 and 7716 patients with premature and extremely premature ASCVD, respectively. Across all facilities, the median (IQR) prescription rate of any statin therapy, HIS therapy, and antiplatelets among patients with premature ASCVD was 0.73 (0.70-0.75), 0.36 (0.32-0.41), and 0.77 (0.73-0.81), respectively. MRR (95% CI) for any statin use, HIS use, and antiplatelet use were 1.53 (1.44-1.60), 1.58 (1.49-1.66), and 1.49 (1.42-1.56), respectively, showing 53, 58, and 49% facility-level variation. The median (IQR) facility-level rate of statin adherence was 0.58 (0.55-0.62) and MRR for statin adherence was 1.13 (1.10-1.15), showing 13% facility-level variation. Similar median facility-level rates and variation were observed among patients with extremely premature ASCVD. CONCLUSIONS: There is suboptimal use and significant facility-level variation in the use of statin and antiplatelet therapy among patients with premature and extremely premature ASCVD. Interventions are needed to optimize care and minimize variation among young ASCVD patients.

Facility-Level Variation in Reported Statin-Associated Side Effects Among Patients with Atherosclerotic Cardiovascular Disease-Perspective from the Veterans Affair Healthcare System.

PURPOSE: Statin-associated side effects (SASEs) can limit statin adherence and present a potential barrier to optimal statin utilization. How standardized reporting of SASEs varies across medical facilities has not been well characterized. METHODS: We assessed facility-level variation in SASE reporting among patients with atherosclerotic cardiovascular disease receiving care across the Veterans Affairs (VA) healthcare system from October 1, 2014, to September 30, 2015. The facility rates for SASE reporting were expressed as cases per 1000 patients with ASCVD. Facility-level variation was determined using hierarchical regression analysis to calculate median rate ratios (MRR [95% confidence interval]) by first using an unadjusted model and then adjusting for patient, provider, and facility characteristics. RESULTS: Of the 1,248,158 patients with ASCVD included in our study across 130 facilities, 13.7% had at least one SASE reported. Individuals with a history of SASE were less likely to be on a statin at follow-up compared with those without SASE (72.0% vs 80.8%, p < 0.01). The median (interquartile range) facility rate of SASE reported was 140.5 (109.4-167.7) cases per 1000 patients with ASCVD. Significant facility-level variation in the rate of SASE reported was observed: MRR 1.38 (1.33-1.44) in the unadjusted model and MRR 1.56 (1.47-1.65) in the adjusted model. CONCLUSION: Significant facility-level variation in SASE reporting was found within the VA healthcare system suggesting room for improvement in standardized documentation of SASEs among medical facilities. This has the potential to lead to improvement in statin utilization.

Lipocalin 2: could it be a new biomarker in pediatric pulmonary hypertension associated with congenital heart disease?

The role of lipocalin 2 (LCN2) in pulmonary hypertension (PH) in pediatric patients with congenital heart disease (CHD) remains unclear. We sought to investigate whether LCN2 could be a potential biomarker for PH in pediatric patients who underwent surgery for CHD. From December 2018 to February 2020, patients undergoing surgical repair for congenital defects with and without PH were identified. Healthy children without CHD and PH served as controls. A mean pulmonary artery pressure (mPAP) >20 mmHg was used as the definition of PH. Blood samples and echocardiograms were obtained in all patients and right heart catheterization was performed in 79 patients. Multivariable logistic regression analysis was used to determine potential predictors for PH. Among 102 patients, the median age was 10 [Interquartile range (IQR) 7.0-13] months, and 37.5% were female. Compared to non-PH patients and controls, PH patients showed elevated levels of LCN2 (P < 0.001). In addition, LCN2 levels positively correlated with the invasive haemodynamic indices of PH. In univariate regression, LCN2 (odds ratio = 2.69 [1.06-5.31], P < 0.001), N-Terminal pro Brain Natriuretic Peptide (NT-proBNP) (OR = 1.91 [1.21-7.56], P = 0.03) and high-sensitive troponin T (hsTnT) (OR = 1.36 [1.01-3.57], P = 0.01) were associated with PH; however, only LCN2 (OR = 1.68 [1.04-4.52], P = 0.03) was significantly associated with PH on multivariate analysis. In conclusion, children with PH had increased LCN2 expression. LCN2 levels positively correlated with invasive indices of PH. These results indicate LCN2 could be a useful biomarker for prediction of PH in pediatric CHD cases.

Prevalence and predictors of cost-related medication nonadherence in individuals with cardiovascular disease: Results from the Behavioral Risk Factor Surveillance System (BRFSS) survey.

Medication nonadherence is highly prevalent among patients with chronic cardiovascular disease. Poor adherence has been associated with increased morbidity and mortality. Medication cost is a major driver for medication nonadherence. Utilizing data from the 2016 to 2018 Behavioral Risk Factor Surveillance System (BRFSS) survey, we estimated the prevalence of cost-related medication nonadherence (CRMNA) among the overall population and among individuals who reported a history of diabetes, atherosclerotic cardiovascular disease (ASCVD), or hypertension. We then performed multivariable logistic regression to analyze sociodemographic factors associated with CRMNA. Our study population consisted of 142,577 individuals of whom 24% were older than 65 years, 47% were men, 66% were White, 17% Black, 35% had hypertension, 13% had diabetes mellitus, and 10% had ASCVD. CRMNA was reported in 10% of the overall population, 12% among those with hypertension, 17% among those with diabetes, and 17% among those with ASCVD. Age below 65 years, female gender, unemployment, lower income, lower educational attainment, having at least 1 comorbidity, and living in a state that did not expand Medicaid were independently associated with CRMNA. The prevalence of CRMNA increased with greater number of these high-risk sociodemographic factors. We conclude that the prevalence of CRMNA is 10% among U.S. adults overall and is higher among those with common chronic diseases. Risk factors associated with CRMNA should be addressed in order to improve adherence rates and health outcomes among high-risk individuals.
