Influence of Clinician-Related Factors on Adherence to the American Heart Association Guidelines for Acute Coronary Syndrome among Clinicians at Kenya Ports Authority Clinics in Mombasa, Kenya

Purpose: The aim of the study was to assess influence of clinician-related factors on adherence to the American heart association guidelines for acute coronary syndrome among clinicians at Kenya Ports Authority clinics in Mombasa, Kenya. Methodology: A descriptive cross-sectional study involving quantitative methods of data collection was adopted. An interviewer administered questionnaire was used for data collection. The study was carried out in Kenya Ports Authority clinics in Mombasa, Kenya. The target population was 106 clinicians attending to patients who present with Acute Coronary Syndrome at the KPA clinics in Mombasa. A census method was used to determine the study participants. The sample size was made up of a hundred and six participants. The clinicians who consented to participate in the study were included while those who were on sick off, leave or who recently joined the clinic were excluded. Pretesting of the study tool was done at the Kenya Pipeline Clinic Mombasa. Data analysis was done using Statistical Package for Social Sciences version 25 and presented via tables. Findings: The study results showed that at 95% level of confidence (ρ-value = 0.05%), there was a significant association between gender (ᾳ=0.025), work experience (ᾳ=0.016), job cadre (ᾳ=0.014) and training received (ᾳ=0.022) on adherence to the American Heart Association Guidelines for Acute Coronary Syndrome among clinicians at Kenya Ports Authority clinics in Mombasa, Kenya. The association was insignificant between age (ᾳ=0.178), education level (ᾳ=0.439) and specialization (ᾳ=0.489) on adherence to the AHA guidelines. Unique Contribution to Theory, Practice and Policy: The study recommends that the KPA management should increase the medical budget to ensure availability of adequate resources for ACS patient management. These resources include adequate staffing, medication, equipment, and staff training costs. The clinic management should ensure that medications such as aspirin, morphine and nitroglycerine are readily available and accessible at patients care points. The KPA clinic management to formulate a simple algorithm that outlines the steps to be taken when managing ACS patients. The study recommends that the clinics should assess their equipment reqularly for maintenance controls to ensure efficiency. The study further recommends random assessments and post care audits to assess the adherence to ACS guidelines among clinicians. Training associated with adherence to the AHA guidelines and as such, KPA should continue offering training and education on the latest AHA guidelines for ACS to ensure updated guidelines for practice.

Most preoperative stress tests fail to comply with practice guideline indications and do not reduce cardiac events.

There is wide variation in stress test utilization before major vascular surgery and adherence to practice guidelines is unclear. We defined rates of stress test compliance at our institution and led a quality improvement initiative to improve compliance with American Heart Association (ACC/AHA) guidelines. We implemented a stress testing order set in the electronic medical record at one tertiary hospital. We reviewed all patients who underwent elective, major vascular surgery in the 6 months before (Jan 1, 2022 - Jul 1, 2022) and 6 months after (Aug 1, 2022 - Jan 31, 2023) implementation. We studied stress test guideline compliance, changes in medical or surgical management, and major adverse cardiac events (MACE). Before order set implementation, 37/122 patients (30%) underwent stress testing within the past year (29 specifically ordered preoperatively) with 66% (19/29) guideline compliance. After order set implementation, 50/173 patients (29%) underwent stress testing within the past year (41 specifically ordered preoperatively) with 80% (33/41) guideline compliance. In the pre- and postimplementation cohorts, stress testing led to a cardiovascular medication change or preoperative coronary revascularization in 24% (7/29) and 27% (11/41) of patients, and a staged surgery or less invasive anesthetic strategy in 14% (4/29) and 4.9% (2/41) of patients, respectively. All unindicated stress tests were surgeon-ordered and none led to a change in management. There was no change in MACE after order set implementation. Electronic medical record-based guidance of perioperative stress testing led to a slight decrease in overall stress testing and an increase in guideline-compliant testing. Our study highlights a need for improved preoperative cardiovascular risk assessment prior to major vascular surgery, which may eliminate unnecessary testing and more effectively guide perioperative decision-making.

Standard cardiopulmonary resuscitation versus chest compressions only after out-of-hospital cardiac arrest: a protocol for a systematic review and meta-analysis

IntroductionThe 2020 American Heart Association guidelines encourage lay rescuers to provide chest compression-only cardiopulmonary resuscitation to simplify the process and encourage cardiopulmonary resuscitation initiation. However, recent clinical trials had contradictory...

Influenza vaccination coverage and determinants of vaccination in peripheral arterial disease patients.

Background: In the latest American Heart Association guidelines, influenza vaccination is recommended for patients with peripheral arterial disease (PAD). The vaccination coverage in this specific population is currently unknown. This study aims to determine the adherence to influenza vaccination in a PAD population and identify associated determinants. Patients and methods. Hospitalized patients and outpatients with PAD from two university departments of vascular medicine were prospectively included. A questionnaire was administered to collect sociodemographic data, cardiovascular risk factors, influenza vaccination status, history of cardiovascular disease, and perception and knowledge about vaccination. Logistic regression was conducted to assess vaccination determinants. Results: Over a six-month period, 494 patients were included (median age 69.5, IQR [63-77], 78% male). Overall, 60.1% were either vaccinated or intended to be (Group 1). Vaccination was associated with age (odds-ratio [OR]=1.055, 95% confidence intervals [95%CI]: 1.035-1.075, p<0.0001), abdominal aorta aneurysm (OR=0.390, 95%CI: 0.229-0.664, p=0.001), chronic obstructive pulmonary disease (OR=0.545, 95%CI: 0.367-0.810, p=0.003), chronic renal disease (OR=0.630, 95%CI: 0.400-0.993, p=0.046), and valvulopathy (OR=2.444, 95%CI: 1.122-5.326, p=0.025). Only 25.3% received vaccination information mainly from their general practitioners. Among patients against vaccination, 59.9% considered themselves not concerned about potential influenza consequences on their PAD, and 37.6% did not intend to change their decision. Conclusions: This study highlights the low adherence to influenza vaccination in the PAD population of 2 university hospital centers. Vaccination is often related to age, and there is a need for adapted information regarding influenza consequences on cardiovascular disease overall, particularly on PAD. Addressing common information and advice about vaccination will be a challenge.

Association Between High-Sensitivity C-Reactive Protein and Metabolic Syndrome Among Hispanic/Latino Participants of the Hispanic Community Health Study/Study of Latinos.

Purpose: To determine whether high-sensitivity C-reactive protein (hsCRP) is associated with incident Metabolic Syndrome (MetS) among U.S. Hispanic/Latino adults. Patients and Methods: The Hispanic Community Health Study/Study of Latinos is a longitudinal observational cohort assessing cardiovascular health among diverse U.S. Hispanic/Latino adults. hsCRP was measured at visit 1 (2008-2011) and classified as low, moderate, or high, based on the Centers for Disease Control and Prevention and American Heart Association (CDC/AHA) guidelines. All MetS components [abdominal obesity, triglycerides, high-density lipoprotein (HDL) cholesterol, blood pressure, and fasting glucose] were measured at visit 1 and visit 2 (2014-2017). MetS was defined as the presence of three or more components based on the 2005 definition from the modified Third Report of the National Cholesterol Education Program Adult Treatment Panel (modified NCEP ATP III). Participants free of MetS at visit 1 and with complete data on hsCRP and all MetS components were included (n = 6121 participants). We used Poisson regression analysis to determine whether hsCRP was associated with incident MetS after adjusting for demographic, behavioral, and clinical factors. All analyses accounted for the complex survey design of the study. Results: In fully adjusted models, moderate versus low hsCRP was associated with a 33% increased risk of MetS [incidence rate ratio (IRR): 1.33, 95% confidence interval (CI): 1.10-1.61], while high versus low hsCRP was associated with a 89% increased risk of MetS (IRR: 1.89, 95% CI: 1.58-2.25). Conclusions: Greater levels of hsCRP were associated with new onset of MetS in a diverse sample of U.S. Hispanic/Latino adults. Results suggest that hsCRP may be an independent risk factor for MetS.

Association between Life's Essential 8 score and high-sensitivity C-reactive protein: A cross-sectional study from NHANES 2015-2018.

Earlier studies showed a negative correlation between life's simple 7 (LS7) and high-sensitivity C-reactive protein (hs-CRP), but no association has been found between life's essential 8 (LE8), an improved version of LS7, and hs-CRP. This study investigated the association between LE8 and hs-CRP utilizing data from the National Health and Nutritional Examination Survey. A total of 7229 adults were incorporated in our study. LE8 was scored according to American Heart Association guidelines, and LE8 was divided into health behaviors and health factors. Serum samples of the participants were used to measure hs-CRP. To investigate the association between LE8 and hs-CRP, weighted linear regression, and restricted cubic spline were utilized. Among 7229 participants, the average age was 48.03 ± 16.88 years, 3689 (51.2%) were females and the median hs-CRP was 1.92 (0.81-4.49) mg/L. In adjusted weighted linear regression, a negative correlation was observed between the LE8 score and hs-CRP. Compared with the low LE8 score, the moderate LE8 score β was -0.533 (-0.646 to -0.420), and the high LE8 score β was -1.237 (-1.376 to -1.097). Health behaviors and health factors were also negatively associated with hs-CRP. In stratified analyses, the negative correlation between LE8 and hs-CRP remained consistent across subgroups. There was a negative correlation between LE8 as well as its sub-indicator scores and hs-CRP. Maintaining a positive LE8 score may be conducive to lowering the level of hs-CRP.

Incorporation of Drone Technology Into the Chain of Survival for OHCA: Estimation of Time Needed for Bystander Treatment of OHCA and CPR Performance.

Drone-delivered automated external defibrillators (AEDs) hold promises in the treatment of out-of-hospital cardiac arrest. Our objective was to estimate the time needed to perform resuscitation with a drone-delivered AED and to measure cardiopulmonary resuscitation (CPR) quality. Mock out-of-hospital cardiac arrest simulations that included a 9-1-1 call, CPR, and drone-delivered AED were conducted. Each simulation was timed and video-recorded. CPR performance metrics were recorded by a Laerdal Resusci Anne Quality Feedback System. Multivariable regression modeling examined factors associated with time from 9-1-1 call to AED shock and CPR quality metrics (compression rate, depth, recoil, and chest compression fraction). Comparisons were made among those with recent CPR training (≤2 years) versus no recent (>2 years) or prior CPR training. We recruited 51 research participants between September 2019 and March 2020. The median age was 34 (Q1-Q3, 23-54) years, 56.9% were female, and 41.2% had recent CPR training. The median time from 9-1-1 call to initiation of CPR was 1:19 (Q1-Q3, 1:06-1:26) minutes. A median time of 1:59 (Q1-Q3, 01:50-02:20) minutes was needed to retrieve a drone-delivered AED and deliver a shock. The median CPR compression rate was 115 (Q1-Q3, 109-124) beats per minute, the correct compression depth percentage was 92% (Q1-Q3, 25-98), and the chest compression fraction was 46.7% (Q1-Q3, 39.9%-50.6%). Recent CPR training was not associated with CPR quality or time from 9-1-1 call to AED shock. Younger age (per 10-year increase; β, 9.97 [95% CI, 4.63-15.31] s; P<0.001) and prior experience with AED (β, -30.0 [95% CI, -50.1 to -10.0] s; P=0.004) were associated with more rapid time from 9-1-1 call to AED shock. Prior AED use (β, 6.71 [95% CI, 1.62-11.79]; P=0.011) was associated with improved chest compression fraction percentage. Research participants were able to rapidly retrieve an AED from a drone while largely maintaining CPR quality according to American Heart Association guidelines. Chest compression fraction was lower than expected.

An Observational Study on Guideline Mediated Prescribing Pattern in Patients with Acute Decompensated Heart Failure

Introduction: Studies on prescribing patterns are useful investigative instruments for figuring out how drugs function in society. Examining the prescription pattern is a crucial part of gauging the ability of medical professionals to choose a medication that will benefit patients to the fullest. The current study goals were to evaluate, using accepted guidelines, the general medicine department's practice of prescribing in accordance with guidelines in a tertiary care hospital and to assess the inclusion of drugs from essential drug list patients with acute decompensated heart failure. Methodology: Hospital based prospective case observational study was conducted for a period of six months after obtaining the permission from institutional ethical committee. The data was collected and analysed according to the inclusion and exclusion criteria and necessary statistical testing like chi square test and pearson correlation were performed. Results and Discussion: Based on the study, the data of total 100 patients (n=100) were evaluated. Gender distribution of data shows high prevalence rate in males. The most commonly high susceptibility of disease age was found in  40-60 in males and females. The maximum number of patients were hospitalized for 6-7 days, hypertension was the most commonly found precipitating factor. Diuretics were prescribed maximum in the prescription. Out of 650 drugs the maximum number of drugs fall under the category of Anti-hypertensives. Most drugs are given through oral route. The American heart association (AHA) guidelines were assessed for drug prescription using IBM SPSS Statistics.  It was depicted that most of the prescriptions were in compliance with the guidelines. Conclusion: The results of our study conclude that prescribing practices were satisfactory according to the American college of cardiology guidelines.

Effect of resuscitative endovascular balloon occlusion of the aorta in nontraumatic out-of-hospital cardiac arrest: a multinational, multicenter, randomized, controlled trial

BackgroundOut-of-hospital cardiac arrest (OHCA) is a significant public health issue worldwide and is associated with low survival rates and poor neurological outcomes. The generation of optimal coronary perfusion pressure (CPP) via high-quality chest compressions is a key factor in enhancing survival rates. However, it is often challenging to provide adequate CPP in real-world cardiopulmonary resuscitation (CPR) scenarios. Based on animal studies and human trials on improving CPP in patients with nontraumatic OHCA, resuscitative endovascular balloon occlusion of the aorta (REBOA) is a promising technique in these cases. This study aims to investigate the benefits of REBOA adjunct to CPR compared with conventional CPR for the clinical management of nontraumatic OHCA.MethodsThis is a parallel-group, randomized, controlled, multinational trial that will be conducted at two urban academic tertiary hospitals in Korea and Taiwan. Patients aged 20–80 years presenting with witnessed OHCA will be enrolled in this study. Eligible participants must fulfill the inclusion criteria, and written informed consent should be collected from their legal representatives. Patients will be randomly assigned to the intervention (REBOA-CPR) or control (conventional CPR) group. The intervention group will receive REBOA and standard advanced cardiovascular life support (ACLS). Meanwhile, the control group will receive ACLS based on the 2020 American Heart Association guidelines. The primary outcome is the return of spontaneous circulation (ROSC). The secondary outcomes include sustained ROSC, survival to admission, survival to discharge, neurological outcome, and hemodynamic changes.DiscussionOur upcoming trial can provide essential evidence regarding the efficacy of REBOA, a mechanical method for enhancing CPP, in OHCA resuscitation. Our study aims to determine whether REBOA can improve treatment strategies for patients with nontraumatic OHCA based on clinical outcomes, thereby potentially providing valuable insights and guiding further advancements in this critical public health area.Trial registrationClinicalTrials.gov NCT06031623.

Gender, Socioeconomic Status, Race, and Ethnic Disparities in Bystander Cardiopulmonary Resuscitation and Education-A Scoping Review.

Social determinants are associated with survival from out-of-hospital sudden cardiac arrest (SCA). Because prompt delivery of bystander CPR (B-CPR) doubles survival and B-CPR rates are low, we sought to assess whether gender, socioeconomic status (SES), race, and ethnicity are associated with lower rates of B-CPR and CPR training. This scoping review was conducted as part of the continuous evidence evaluation process for the 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care as part of the Resuscitation Education Science section. We searched PubMed and excluded citations that were abstracts only, letters or editorials, and pediatric studies. We reviewed 762 manuscripts and identified 24 as relevant; 4 explored gender disparities; 12 explored SES; 11 explored race and ethnicity; and 3 had overlapping themes, all of which examined B-CPR or CPR training. Females were less likely to receive B-CPR than males in public locations. Observed gender disparities in B-CPR may be associated with individuals fearing accusations of inappropriate touching or injuring female victims. Studies demonstrated that low-SES neighborhoods were associated with lower rates of B-CPR and CPR training. In the US, predominantly Black and Hispanic neighborhoods were associated with lower rates of B-CPR and CPR training. Language barriers were associated with lack of CPR training. Gender, SES, race, and ethnicity impact receiving B-CPR and obtaining CPR training. The impact of this is that these populations are less likely to receive B-CPR, which decreases their odds of surviving SCA. These health disparities must be addressed. Our work can inform future research, education, and public health initiatives to promote equity in B-CPR knowledge and provision. As an immediate next step, organizations that develop and deliver CPR curricula to potential bystanders should engage affected communities to determine how best to improve training and delivery of B-CPR.

Abstract WP279: Stroke in Young Adults With Congenital Heart Disease a Single Center Case Control Study

Introduction: Adults with congenital heart disease (ACHD) are at risk for stroke, but risk factors within this population are not well characterized. Methods: We reviewed medical records of patients evaluated in an ACHD clinic from 8/1/1995- 3/1/2022 who underwent brain imaging for any reason. We categorized patients by anatomical complexity based on American Heart Association guidelines (simple, moderate or high complexity). The primary outcome was ischemic or hemorrhagic stroke. TIA and silent infarcts were excluded. We created logistic regression models to calculate odds ratios (OR) and 95% confidence intervals (CI) for the association between anatomic complexity and stroke. Results: Out of 184 patients, 48 (26.1%) had any stroke (62% ischemic, 38% hemorrhagic). Median age at first stroke was 26.2 years (IQR 19.2-38.5) (Figure). Those with stroke had higher proportion of Black race, more major cardiac surgeries, and more use of antithrombotic medications prior to stroke (see Table). Adjusting for age, sex, race, number of cardiac surgeries, and use of antithrombotic medications, those with highly complex lesions had a trend towards higher odds of any stroke (adjusted OR 2.0, 95% CI 0.89 - 4.4). Effect size was higher for ischemic stroke (adjusted OR 2.6, 95% CI 0.99-6.7). Conclusion: In our sample of 184 ACHD patients who underwent brain imaging, stroke was common with half of strokes occurring before the age of 26 years. High complexity cardiac lesions were associated with more than double the odds of ischemic stroke. Larger studies are needed to develop effective stroke prevention strategies in this growing young adult population.

Abstract TMP63: Blood Pressure (BP) Protocol Violations in IV Tenecteplase Treated Ischemic Stroke Patients is Associated With Early Neurologic Deterioration and Symptomatic Intracranial Hemorrhage

Background: The American Heart Association guidelines recommend BP goal of &lt;180/105 mmHg for the first 24 hours in acute ischemic stroke (AIS) patients treated with IV Alteplase and now adopted for IV Tenecteplase (TNK). Studies suggest increased hemorrhage risk in patients with BP ≥170 mmHg and greater BP variability. Methods: We performed a retrospective study with data from the Get with The Guidelines database and electronic medical record of all adult AIS patients treated with TNK at a Comprehensive Stroke Center from 6/2021 to 6/2023. All BP readings from ED arrival to 24 hours post TNK were queried. We analyzed the temporal trends of BP characteristics and their association with early neurological deterioration (END) and symptomatic intracranial hemorrhage (sICH). The BP characteristics included mean and standard deviation of systolic (SBP) and diastolic (DBP) measurements, intra-patient BP variability and frequency of excessive BP (SBP &gt; 180 mmHg and DBP &gt; 105 mmHg) at each time point. Results: There were 132 TNK treated patients: mean age 68 ± 15 years, 54% male, 73% Caucasian, median admission NIHSS 9, IQR 4-15, 42 (32%) underwent mechanical thrombectomy, 72 (54.5%) treated with IV antihypertensive(s). Of these, 6 (4.5%) developed END and another 6 (4.5%) sICH. Of the 5901 BP measurements, 217 (3.7%) and 99 (1.7%) exceeded systolic of &gt;180 mmHg and diastolic of &gt;105 mmHg respectively. All END and sICH patients had excessive BP within 4 hours post TNK (Figure 1) and during this time there was a strong association of END with excessive SBP (14% vs 4.8%; p=0.05) and DBP (14% vs 1.2%; p &lt; 0.001). sICH had a similar but weaker association: excessive SBP (7.7% vs 4.9%; p=0.3) and excessive DBP (3.8% vs 1.4%; p=0.2). Conclusion: Our findings suggest that excessive BPs within 4 hours of TNK may be associated with patients developing END and sICH. Further exploration of moderate BP parameters deserve further study post thrombolysis, like the BEST II study in post thrombectomy patients.

Dual Antiplatelet Therapy for the Acute Management and Long-term Secondary Prevention of Ischemic Stroke and Transient Ischemic Attack, An Updated Review.

To improve the efficacy over antiplatelet monotherapy, dual antiplatelet therapy (DAPT) has been increasingly adopted in the management of non-cardioembolic stroke. For minor ischemic stroke and high-risk transient ischemic attack, the aspirin-clopidogrel combination is now recommended for acute short-term treatment, whereas aspirin-ticagrelor combination may be considered in selected patients, especially those with resistance to clopidogrel. For long-term stroke prevention, aspirin-dipyridamole combination has been used as an alternative to antiplatelet monotherapy, and aspirin or clopidogrel combined with cilostazole may be prescribed for added protection in high-risk patients. In this paper, we review the development of DAPT from a historical perspective and describe the findings from major clinical trials published up until the end of 2023. Using the 2021 American Heart Association guideline for secondary stroke prevention as a basis for our recommendations, we further discuss areas of controversy and more recent developments to provide an updated review for clinicians to consider in their daily practice.

CT angiography prior to endovascular procedures: can artificial intelligence improve reporting?

CT angiography prior to endovascular aortic surgery is the standard non-invasive imaging method for evaluation of aortic dimensions and access sites. A detailed report is crucial to a proper planning. We assessed Artificial Intelligence (AI)-algorithm accuracy to measure vessels diameters at CT prior to transcatheter aortic valve implantation (TAVI). CT scans of 50 patients were included. Two Radiologists with experience in vascular imaging together manually assessed diameters at nine landmark positions according to the American Heart Association guidelines: 450 values were obtained. We implemented TOST (Two One-Sided Test) to determine whether the measurements were equivalent to the values obtained from the AI algorithm. When the equivalence bound was a range of ± 2mm the test showed equivalence for every point; if the range was equal to ± 1mm the two measurements were not equivalent in 6 points out of 9 (p-value > 0.05), close to the aortic valve. The time for automatic evaluation (average 1min 47s) was significantly lower compared with manual measurements (5min 41s) (p < 0.01). In conclusion, our results indicate that AI-algorithms can measure aortic diameters at CT prior to endovascular surgery with high accuracy. AI-assisted reporting promises high efficiency, reduced inter-reader variabilities and time saving. In order to perform optimal TAVI procedure planning aortic root analysis could be improved, including annulus dimensions.

2023 American Heart Association and American Academy of Pediatrics Focused Update on Neonatal Resuscitation: An Update to the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

This 2023 focused update to the neonatal resuscitation guidelines is based on 4 systematic reviews recently completed under the direction of the International Liaison Committee on Resuscitation Neonatal Life Support Task Force. Systematic reviewers and content experts from this task force performed comprehensive reviews of the scientific literature on umbilical cord management in preterm, late preterm, and term newborn infants, and the optimal devices and interfaces used for administering positive-pressure ventilation during resuscitation of newborn infants. These recommendations provide new guidance on the use of intact umbilical cord milking, device selection for administering positive-pressure ventilation, and an additional primary interface for administering positive-pressure ventilation.

Hypertension and other vascular risk factors in patients with functional seizures

ObjectiveRecent literature has suggested that functional seizures are associated with an elevated risk for vascular disease and mortality. We investigated the prevalence of risk factors for vascular disease in patients who were admitted to the epilepsy monitoring unit. MethodsPatients who were admitted to the epilepsy monitoring unit and received a definitive diagnosis of either functional seizures or epilepsy were identified. Data collected included demographic, clinical characteristics, medication list, comorbidities, and scheduled blood pressure measurements that occurred every 12 h during the admission. The mean blood pressures were calculated and if they were above the American College of Cardiology and the American Heart Association guideline cutoff of 130/80 mm Hg or the patient had a documented history of hypertension the patient was counted as having the condition. A multiple logistic regression model was developed to evaluate the independent association of the patient’s diagnosis (i.e., epilepsy or functional seizures) and vascular risk factors that controlled for the number of blood pressure measurements, age, sex, and if the patient was taking antihypertensive medications. Results270 patients were included in this study of which 147 patients had epilepsy and 123 had functional seizures. Among those with functional seizures, 57.72 % had either a history of hypertension or a mean blood pressure above 130/80 compared to 38.78 % of those with epilepsy (p = 0.0022). In addition, 30.89 % of functional seizures patients had hyperlipidemia and 63.41 % were obese. The logistic regression model indicated that functional seizures were independently associated with high blood pressure (OR: 2.47, 95 % CI 1.10–5.69), hyperlipidemia (OR: 3.38, 95 % CI 1.35–8.86), and obesity (OR: 4.25, 95 % CI 2.22–8.36) compared to those with epilepsy. There was no significant difference in the prevalence of diabetes (OR: 0.81, 95 % CI 0.24–2.77) or current tobacco use (OR: 1.04, 95 % CI 0.48–2.25) between the groups. SignificancePatients with functional seizures had an elevated prevalence of several vascular risk factors. These findings may partially account for complications associated with functional seizures and have implications related to their pathophysiology.

Multicenter exploration of tenecteplase transition factors: A quantitative analysis

BackgroundTenecteplase (TNK) is gaining recognition as a novel therapy for acute ischemic stroke (AIS). Despite TNK offering a longer half-life, time and cost saving benefits and comparable treatment and safety profiles to Alteplase (ALT), the adoption of TNK as a treatment for AIS presents challenges for hospital systems. ObjectiveIdentify barriers and facilitators of TNK implementation at acute care hospitals in Texas. MethodsThis prospective survey used open-ended questions and Likert statements generated from content experts and informed by qualitative research. Stroke clinicians and nurses working at 40 different hospitals in Texas were surveyed using a virtual platform. ResultsThe 40 hospitals had a median of 34 (IQR 24.5–49) emergency department beds and 42.5 (IQR 23.5–64.5) inpatient stroke beds with 506.5 (IQR 350–797.5) annual stroke admissions. Fifty percent of the hospitals were Comprehensive Stroke Centers, and 18 (45 %) were solely using ALT for treatment of eligible AIS patients. Primary facilitators to TNK transition were team buy-in and a willingness of stroke physicians, nurses, and pharmacists to adopt TNK. Leading barriers were lack of clinical evidence supporting TNK safety profile inadequate evidence supporting TNK use and a lack of American Heart Association guidelines support for TNK administration in all AIS cases. ConclusionUnderstanding common barriers and facilitators to TNK adoption can assist acute care hospitals deciding to implement TNK as a treatment for AIS. These findings will be used to design a TNK adoption Toolkit, utilizing implementation science techniques, to address identified obstacles and to leverage facilitators.

Apparent Treatment-Resistant Hypertension in the First Year Associated with CV Mortality in PD Patients.

Few reports have focused on the association between apparent treatment-resistant hypertension (aTRH) and cardiovascular (CV) mortality in peritoneal dialysis (PD) population, thus we conducted this retrospective cohort to explore it.Patients and Methods: This was a retrospective cohort study conducted from January 2011 to January 2020 with PD patients in 4 Chinese dialysis centers. ATRH was defined according to the American College of Cardiology and American Heart Association guidelines. ATRH duration was calculated as the total number of months when patients met the diagnostic criteria in the first PD year. The primary outcome was CV mortality, and the secondary outcomes were CV events, all-cause mortality, combined endpoint (all-cause mortality and transferred to HD), and PD withdrawal (all-cause mortality, transferred to HD and kidney transplantation). Cox proportional hazards models were used to assess the association. A total of 1,422 patients were finally included in the analysis. During a median follow-up period of 26 months, 83 (5.8%) PD patients incurred CV mortality. The prevalence of aTRH was 24.1%, 19.9%, 24.6% at 0, 3, 12 months after PD initiation respectively. Overall, aTRH duration in the first PD year positively associated with CV mortality (per 3 months increment, adjusted HR, 1.29; 95% CI 1.10, 1.53; P=0.002). After categorized, those with aTRH duration more than 6 months presented the highest adjusted HR of 2.92. Similar results were found for secondary outcomes, except for the CV event. Longer aTRH duration in the first PD year is associated with higher CV mortality and worse long-term clinical outcomes. Larger studies are warranted to confirm these findings.

Delayed Prescribing of Non-Vitamin K Antagonist Oral Anticoagulants (NOACs) in Patients with Low Socioeconomic Status

Background/Objective: Atrial fibrillation (AF) and venous thromboembolism (VTE) are conditions with significant morbidity and mortality when left untreated. American Heart Association guidelines changed in 2019 to make non-vitamin K antagonist oral anticoagulants (NOACs) the preferred method for preventing stroke and systemic embolism in patients with AF or history of VTE. NOACs were first introduced to the United States in 2010 and now include dabigatran, apixaban, rivaroxaban, and edoxaban. There is a dearth of research concerning the speed with which new treatments are prescribed to those in different socioeconomic status (SES) groups. We hypothesized that patients with lower SES were prescribed NOACs later than higher SES counterparts following the introduction of NOACs in 2010.&#x0D; Methods: The IU Cardiovascular Research Consortium/Sidus Dataset was mined for AF and VTE patients prescribed a NOAC between 2010 and 2022. The SES groups were determined using 2020 U.S. Census income data that correlated to patients’ zip codes. The yearly number ofpatients in each SES group were compared to assess for proportional uptake of NOAC prescribing. The primary outcome was the proportion of low SES to high SES prescribing over each year between 2010 and 2022.&#x0D; Results: Low SES patients (n=101,945) were prescribed NOACs at an average of 0.65 times the rate of high SES patients (n= 89,130) from 2010 to 2012, the first three years of NOAC market availability. Prescribing rates equilibrated in 2013 and low SES prescribing has outpaced high SES prescribing since 2021.&#x0D; Conclusion/Impact: Low SES patients experienced a three year delay in receiving NOAC prescriptions at the same rate as their high SES counterparts. Systemic changes, like more frequent prescribing guideline updates and improved evidence-based education amongst providers in low-income areas, could prevent a similar delay when introducing similarly transformative treatments in the future.
