Circulation, Volume 150, Issue Suppl_1, Page A4141438-A4141438, November 12, 2024. Background:Catheter ablation is a well-established treatment for atrial fibrillation (AF). Left atrial low-voltage areas (LVAs) is associated with atrial remodeling following the progression of atrial cardiomyopathy, and poor rhythm outcome after catheter ablation. However, the predictors of LVAs presence have not been fully elucidated in different age groups.Purpose:The purpose of this study was to investigate predictors of the prevalence of LVAs in different age groups.Methods:1,488 (age, 69 ± 10 years; female, 501 [34%]) consecutive patients who underwent initial ablation were included. Age groups were divided into three groups, namely

INTRODUCTION:Coronary CT angiography (CCTA) is a powerful noninvasive tool for identifying high-risk plaque, such as low-density non-calcified plaque (LD-NCP). Though, the optimal treatment of patients with LD-NCP remains unclear. This study explored the association of revascularization in the setting of LD-NCP with the occurrence of acute coronary syndrome (ACS).Methods:This was a post-hoc analysis of the ICONIC study. A subset of 234 patients that underwent CCTA with subsequent ACS were matched to 234 control patients who also underwent CCTA but did not have ACS during follow-up. Patients were also followed for occurrence of revascularization, either coronary artery bypass graft or percutaneous coronary intervention. Atherosclerosis imaging-enabled quantitative CT (AI-QCT) was used to measure diameter stenosis, and LD-NCP, non-calcified plaque, and calcified plaque volumes from each CCTA. LD-NCP was defined as plaque with -190 to 30 Hounsfield Units. Patients were stratified based on the presence of LD-NCP. Subgroup analysis was conducted to compare the occurrence of ACS with the rate of revascularization. Kaplan-Meier survival curves and extended Cox regression analysis were used to evaluate the effect size of revascularization and LD-NCP on occurrence of ACS.Results:AI-QCT was completed in 448/468 subjects (follow-up time [MEAN±SD] 2.44±2.48 years). The median of LD-NCP was 1.2 mm3for patients with >0 mm3LD-NCP. There were 85 patients with LD-NCP >1.2 mm3and 363 patients with LD-NCP ≤1.2 mm3. In patients with LD-NCP >1.2 mm3, the rate of revascularization in patients with and without ACS was 3/52 (5.8%) versus 14/33 (42.4%) (p1.2 mm3and revascularization were less likely to have ACS during follow-up (adjusted HR: 0.20 [0.07, 0.61]; p=0.005). Additionally, patients with LD-NCP >1.2 mm3who did not undergo revascularization were more likely to have ACS (adjusted HR: 1.47 [1.03, 2.12]; p=0.036). Hazard ratios were adjusted for diameter stenosis, and non-calcified and calcified plaque volume. Time-dependent coefficients were included for diameter stenosis.Conclusion:Revascularization of patients with LD-NCP >1.2 mm3identified on CCTA with AI-QCT was associated with less risk for ACS.

Background:Invasive coronary reactivity testing (CRT) is the gold standard for comprehensive assessment of coronary endothelial and microvascular dysfunction in patients with angina and non-obstructive CAD (ANOCA). Non-invasive imaging modalities (PET and CMR) have emerged as potential alternatives. However, due to the inability to systemically administer acetylcholine, patients with normal coronary flow reserve (CFR) but abnormal endothelial function on invasive Ach testing are systemically missed on non-invasive testing. We aimed to assess the prevalence of coronary endothelial dysfunction in ANOCA patients with normal CFR.Methods:Consecutive patients undergoing CRT at our institution were included. Those with normal adenosine-based CFR ( >2.5), were further stratified as having normal coronary endothelial function (NEF, 50% increase in coronary blood flow in response to ACh) vs abnormal endothelial function (AEF, >20% epicardial coronary diameter constriction and/or

Introduction:Anomalous Left Coronary Artery Arising from the Pulmonary Artery (ALCAPA), also known as Bland-White-Garland syndrome, is a rare congenital anomaly(incidence:1 in 300,000 live births) typically presenting during infancy. Adult presentations are even rarer due to a high mortality rate of nearly 90% in the first year of life without surgical intervention. This report examines an adult patient with exercise-induced chest pain who received a delayed diagnosis of ALCAPA via multimodal imaging.Case Summary:A 21-year-old male presented to the emergency department(ED) with severe retrosternal chest pain radiating to both shoulders and arms, which began during exercise 30 minutes prior. He had a history of similar, milder episodes during exercise, previously treated as musculoskeletal pain and gastroesophageal reflux disease in the ED. His medical, social, and family histories were unremarkable. Physical examination revealed a soft, continuous murmur along the left sternal border. During this visit, An EKG done showed sinus tachycardia at 110 bpm and deep T-wave inversions in the anterolateral leads, a dynamic ST-T changes from his baseline.Serial Cardiac biomarkers and a lipid profile were within normal ranges. Initially managed for acute coronary syndrome-unstable angina with antithrombotic therapy, beta-blockers, and nitrates, he underwent urgent coronary angiography. This revealed a dilated right coronary artery (RCA) with retrograde flow to the left coronary artery (LCA) into the main pulmonary artery (PA) via collaterals, with no evidence of atherosclerosis (Figure 1).Echocardiography (Figure 2) and coronary CT angiography (Figure 3) confirmed the diagnosis of ALCAPA. The patient underwent successful surgical repair with aortic reimplantation of the LCA and was discharged in good health.Discussion:In adult ALCAPA patients, good collateral circulation may develop; however, myocardial ischemia can occur due to the “coronary steal phenomenon” and poor collateral flow regulation, leading to angina, arrhythmias, and sudden cardiac death. ALCAPA should be considered a differential diagnosis in adults presenting with exercise intolerance, as most sudden cardiac death cases occur by the fourth decade. A high index of clinical suspicion and a multimodality imaging approach is essential for the early diagnosis of this rare coronary anomaly, underscoring the critical role of early surgical intervention in preventing catastrophic, life-threatening events.

Introduction:Despite early mitigation efforts, the opioid pandemic in the United States has persisted and affected many Americans. A public health emergency was declared urging all prescribers to use caution in prescribing opioids. Alternative approaches to postoperative pain management during transvenous cardiac device implants (TCDI) in adults have not been described.Methods:We report a single-center retrospective analysis of 612 consecutive patients that underwent TCDI between January 2021 and January 2024 with ultrasound guided pectoral nerve block (PNB) using liposomal bupivacaine prior to implant for postoperative pain management. Pain scores (0-10) were recorded systematically in the postoperative period, at discharge, and at wound check follow-up. Any need for opioid use in the postoperative period was recorded as well.Results:A total of 612 patients were evaluated, 50% female with a mean age of 71.2 years. All patients received PNB successfully with no device site infection or hematomas. The mean Visualized Analog Scale (VAS) pain scores at 1, 3, and 5 hours after the procedure, at discharge, and at the follow-up visit were 1.93, 1.22, 1.10, 1.05, and 0.13 respectively. During follow-up, no patients required opioids for pain control throughout the entire postoperative period of 14 days.Conclusion:Pectoral nerve block with liposomal bupivacaine can be performed safely preoperatively during TCDI and provides adequate pain control without need for opioid use postoperatively. Further research is needed to assess broad scale implications of this approach to larger patient populations.

Circulation, Volume 150, Issue Suppl_1, Page A4127919-A4127919, November 12, 2024. Intro:DSP-encoded desmoplakin is implicated in a distinct form of arrhythmic cardiomyopathy (ACM), often involving the LV and characterized by myocardial inflammation. Conventional ACM diagnostic criteria has poor sensitivity forDSP-associated ACM, thus highlighting the need to identify the full spectrum of phenotypic risk associated with disease-associatedDSPvariants.Objective:To analyze the genotypic and phenotypic spectrum ofDSP-mediated disease at a large population level.Methods:UK Biobank participants with exome sequencing (ES) were included. Variants were filtered by gene evidence category, yielding 3 groups: predicted deleterious (pDel); subset with predicted loss of function (LOF); and ultra-filtered subset by ClinVar 2* pathogenic/likely pathogenic (P/LP). Phenotypic penetrance was analyzed withDSP-neg individuals as control. Variant location analysis assessed LOFs by susceptibility to nonsense mediated decay region and missenses by amino acid sequence to identify mutational hotspots where P/LPs localize.Results:Out of 200,580 with ES, 1407DSPcarriers had pDel, 168 with LOF, and 44 with ClinVar 2* P/LP.DSPcarriers had higher burden of myocarditis, cardiomyopathy (CM), and heart failure. A progressive enrichment in myocarditis and CM was observed by more stringent variant filtering inDSPcarriers compared to control. A higher proportion ofDSPcarriers had myocarditis – 0.28% (4) of the pDels, 1.8% (3) of LOFs, and 4.5% (2) compared to control 0.07% (p

Circulation, Volume 150, Issue Suppl_1, Page A4147079-A4147079, November 12, 2024. Introduction:Observational studies in heart failure (HF) patients have shown that low levels of the thyroid hormone triiodothyronine (T3) with otherwise normal thyroid testing (‘low T3 syndrome’) is a risk factor for adverse clinical outcomes. Preclinical studies have shown beneficial effects from T3 therapy on myocardial contractility, myocardial relaxation, and vascular resistance, but human studies are lacking.Research Question:In patients with HF and low T3 syndrome, is oral liothyronine (LT3) safe, and does it impact cardiovascular clinical and physiologic phenotypes?Aims:Primary aim: To evaluate the safety of oral LT3 therapy in HFrEF and HFpEF. Secondary aim: To evaluate the feasibility and preliminary efficacy of oral LT3 therapy in HFrEF and HFpEF.Methods:A total of 28 participants with HFrEF and 28 with HFpEF aged 18+ years enrolled in a single-center, randomized, double-blind, placebo-controlled, crossover trial and were prescribed LT3 or placebo for 8 weeks with a 2-week washout period. Primary outcomes were safety as assessed by T3 level; arrhythmic events by EKG, 14-day adhesive patch monitoring, and ICD (HFrEF only); and adverse events. Secondary efficacy outcomes included Kansas City Cardiomyopathy Questionnaire, NT-proBNP level, peak O2 consumption during a cardiopulmonary exercise test, and actigraphy. Secondary mechanistic outcomes included non-invasive assessments of cardiac and arterial function measured via echocardiography and arterial tonometry.Results:Low T3 syndrome was present in 20% of screened participants. After LT3 treatment, T3 levels markedly increased compared with placebo. Heart rate was higher on LT3 (mean difference 2.4 beats per minute, p

Background:Social isolation and loneliness have been found to be associated with many chronic diseases including cardiovascular disease (CVD) and those with both CVD and social isolation may have a worse prognosis. Cardiac rehabilitation (CR) has been shown to improve outcomes following cardiac events. We hypothesize that CR may have beneficial impacts on quality of life, social support, depression, and pain rated via Dartmouth COOP Charts (COOP).Research Question:What is the impact of cardiac rehabilitation on quality of life, perceived social support, depression, and chronic pain?Methods:Data from Penn State Hershey Medical Center’s CR program was extracted pre-and post-CR, including Body Mass Index (BMI), Metabolic Equivalents (METs) performed, and components of COOP (social support, quality of life (QoL), depression, pain), with impairment rated from 1 to 5, with 5 representing worse impairment. Analysis was performed with paired t-test. Sensitivity analysis was performed including only high-risk participants (pre-rehab COOP score ≥ 3) for social support, depression, and pain as well as BMI ≥ 30 kg/m2.Results:A total of 743 participants were included with a mean (±SD) age of 66.3 (±11.3) years. CR improved METs performed, QoL, depression, and pain (Table 1). When analyzing all participants, CR did not improve social support or BMI. However, when only analyzing those with higher social support needs at baseline (n= 78) as well as elevated BMI ≥30kg/m2, CR was associated with improved social support and BMI. QoL, depression and pain also improved among the higher risk groups (Table 2).Conclusion:CR programs have demonstrated benefits for cardiovascular mortality and may have powerful impacts on patients’ mental health, pain, and social support. Further studies are needed to further elucidate the role CR may have in improving outcomes in participants with social isolation and loneliness.

Circulation, Volume 150, Issue Suppl_1, Page A4136277-A4136277, November 12, 2024. Introduction:The most common acute coronary syndrome (ACS) symptom is chest pain. Chest pain is an umbrella term more precisely described using words like pressure or tightness. Previous studies have not explored the lay public’s conceptions of ACS-related chest pain. Misconceptions about chest pain make it difficult for individuals to recognize this symptom if they were to experience it, delaying care seeking.Research Question:How does the lay public conceive of ACS-related chest pain?Methods:Participants from across the U.S. were recruited in May and June 2023. Participants completed an online survey including the Chest Pain Conception Questionnaire. Descriptive statistics were used to characterize conceptions of chest pain quality, timing, intensity, and distress. Conceptions of men and women were compared using the independent-samplest-test and Chi-square test.Results:Participants (n=597) were mostly women (n=355; 59.5%) with a mean age of 54.0 years (SD = 11.5). The sample was diverse: White (n=414, 69.2%), Black (n=101; 16.9%), Hispanic or Latina/o/e/x (n=96; 16.1%), and Asian (n=67; 11.2%). Participants often thought of pressure (78.9%), tightness (77.4%), squeezing (75.5%), gripping (72.9%), and heaviness (72.5%) as possible descriptors of ACS-related chest pain. They less often thought of discomfort (48.7%), fullness (16.8%), and indigestion (13.4%). Participants expected ACS-related chest pain to be “intense” and to bother them “a lot,” both with median scores of 4.0 on a 5-point Likert scale. Participants felt that ACS-related chest pain would “often” (median 4.0) occur with activity and “sometimes” (median 3.0) occur at rest. Women were more likely to rate specific descriptors of chest pain (i.e., pressure, tightness) and general descriptors of chest pain (i.e., discomfort, pain) as more likely ACS-related chest pain descriptors than men, (allps≤ .05). Women (n=58; 16.3%) were about twice as likely as men (n=22; 9.2%) to endorse indigestion as a possible descriptor of ACS-related chest pain, (p= .013, OR = 0.52 [95% CI = 0.31-0.87]).Conclusions:As many as 1 in 5 participants did not endorse common descriptors such as pressure and tightness as potentially characterizing ACS-related chest pain. Most believed this symptom would be intense and bother them a lot. They also more often associated ACS-related chest pain with activity than with rest. Clinical and research interventions can target the misconceptions identified in this study.

Circulation, Volume 150, Issue Suppl_1, Page A4138273-A4138273, November 12, 2024. Background:Rheumatic heart disease (RHD) causes 305,000 premature annual deaths, and education is one of the strategies to diminish disease burden. International RHD foundations aim do provide preventive and control efforts for RHD. We aimed to assess the acceptability and gain of knowledge of a series of education flipcharts presented during screening programs in high-burden areas of Brazil.Methods:Four flipcharts (“Introduction to rheumatic fever (RF) and RHD”, “RHD and pregnancy”, “RHD and surgery” and “RHD community awareness”) were developed over 3 years and taught during 36 months to patients, community, health and education professionals in Minas Gerais state. Training included in-person interactions and virtual workshops. Pre and post-training questionnaires were applied through an online and printed surveys in 2021 and 2022, and post-education evaluations were conducted from January 2023 to April, 2024.Results:Flipchart training was successfully delivered to 112 education professionals, 574 health providers and 598 community members (N=1284): 899 (70%) were enrolled in primary care, and 1109 (86%) responded the surveys. Among respondents of the survey for health and education professionals (N=589), 240 (41%) had been educated about RHD in the previous year. 569 (96%) learned any new information; the content was all new for 21 (4%). Nearly all professionals reported that flipcharts could improve patients’ lives (571, 97%) and felt confident to use the tool with someone with no knowledge about RHD (533, 91%); 86% of the teachers said they would use flipcharts as educational tools. In the survey for community / schoolchildren (N=520) only 128 (25%) respondents had previous education on RHD, 510 (98%) reported that learned new information, and content was completely new for 242 (47%). A total of 430 (83%) individuals reported that they will discuss RHD with families and community. All qualitative written reports were positive. In 2021/2022, 218/485 (45%) health and education professionals responded the pre/post questionnaire. Knowledge about RHD increased after training: RF as the cause of RHD (56% vs 86%), use of Benzathine Penicillin G (50% vs 97%), frequency of antibiotic prophylaxis (32% vs 90%) and overall moderate or expert understanding of RF or RHD (30% vs 82%).Conclusion:Flipchart educational sessions about RHD had a very positive acceptability in high-risk Brazilian populations, with remarkable gain of knowledge for health professionals.

Circulation, Volume 150, Issue Suppl_1, Page A4141710-A4141710, November 12, 2024. Background:Stress perfusion CMR has excellent diagnostic and prognostic values in assessing chest pain syndromes. AI-guided methods may overcome complex scanning and increase clinical adaptation of stress CMR.Aim:To assess the benefits of AI-guided stress perfusion CMR.Methods:Consecutive patients with stable chest pain underwent stress CMR using either a standard scanning method (SOC) or an AI-assist (AIA) machine learning protocol to automate scan planning, plane prescription, sequence tuning, and image reconstruction. Scan duration, the ratio of scan preparation time over the entire scan duration, and scan quality using a 5-point scale were compared between AIA and SOC. Cox regression models were constructed to associate evidence of ischemia on stress CMR, by either scanning method, with composite endpoints including cardiovascular death, non-fatal MI, unstable angina hospitalization, and late CABG. A second composite endpoint included the performance of additional cardiac imaging tests (stress imaging and CCTA) and invasive coronary procedures after CMR.Results:Among 594 patients (62.8 ± 14 years), 29% underwent stress CMR with AIA. 26% had stress-perfusion ischemia, and 39% had LGE present. AIA stress CMR had lower scan duration (median 44.0 [IQR 40-47] vs. 52.5 min [IQR 46-60]; p

Circulation, Volume 150, Issue Suppl_1, Page A4147770-A4147770, November 12, 2024. Background:Randomized control trials (RCTs) have compared transcatheter aortic valve replacement (TAVR) with surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis (AS) at low-intermediate surgical risk.Objective:To compare TAVR vs. SAVR for AS in low-intermediate surgical risk patients.Methods:We systematically searched PubMed, Scopus, and Cochrane Central databases for studies comparing TAVR with SAVR for AS in low-intermediate surgical risk. Outcomes included composite death or stroke, death, stroke, myocardial infarction (MI), cardiac death, new atrial fibrillation (AF), new pacemaker implantation, acute kidney injury (AKI), bleeding, major vascular complications, endocarditis, aortic valve reintervention, and rehospitalization at 1 year. Random effects models were used to generate risk ratios (RRs) with 95% confidence intervals (CIs). Heterogeneity was assessed using I2statistics.Results:The systematic review identified 8 RCTs including 9,239 patients (TAVR n=4,695, 50.8%). Death or stroke (RR 0.78; 95%CI 0.62-0.98; p=0.033; I2=52%), cardiac death (RR 0.79; 95%CI 0.63-0.98; p=0.029; I2=1%), bleeding (RR 0.39; 95%CI 0.25-0.60; p

Circulation, Volume 150, Issue Suppl_1, Page A4140003-A4140003, November 12, 2024. Background:Hypertension is a major preventable risk factor for cardiovascular (CV) disease. Emerging evidence suggests that in addition to blood pressure (BP) levels, controlling the consistency of BP is a key determinant of clinical outcomes. We aimed to assess the effects of consistency of BP control on adverse CV and renal outcomes using two metrics: long-term variability of systolic BP (LT-BPV) and the degree at which BP control is achieved, known as cumulative systolic BP load (CBPL).Methods:We collected clinic systolic BP (SBP) measurements from UK Biobank primary care records in those diagnosed with hypertension (N=39,816), chronic kidney disease (CKD, N=8,062), and neither of these (N=17,702), including a per-participant mean of 21 SBP values over 6 years. Instances of the primary outcome, 4-point major adverse cardiovascular events (MACE; stroke, acute myocardial infarction, heart failure hospitalization, and cardiovascular-related death), were collected from hospital records. Per-standard deviation (SD) and per-quartile hazard ratios (HR) were used to estimate LT-BPV, CBPL, and mean SBP separately using adjusted Cox regression. Sensitivity analyses were used to determine the independence of BP consistency effects from mean BP levels.Results:In those with hypertension, each per-SD increase in LT-BPV was associated with increased risk for MACE (HR=1.12, p=4.4E-11), specifically CV-related death, stroke, and HF hospitalization. LT-BPV effect estimates were strongest in those with controlled SBP and the strongest predictors for all events in those without high-risk comorbidities (coronary artery disease, CKD, peripheral vascular disease, and diabetes). CBPL was similarly associated with MACE (HR=1.13, p=8.1E-13), specifically stroke and acute myocardial infarction, but not with fatal events or HF. In those with CKD, both LT-BPV and CBPL were associated with progression to renal failure (HR=1.31-1.33, p

Circulation, Volume 150, Issue Suppl_1, Page A4140323-A4140323, November 12, 2024. Introduction:Individuals with low socioeconomic status (SES) have a higher risk of CVD events yet are less likely to utilize outpatient cardiac rehabilitation (OCR), which is an evidence-based secondary prevention strategy. Understanding barriers and facilitators to the implementation of OCR among individuals with low SES is critical to design targeted interventions to improve attendance.Aims:To identify barriers and facilitators to OCR attendance among individuals with low SES using the Capability, Opportunity, Motivation, and Behavior (COM-B) theoretical model.Methods:We purposefully recruited patients for in-depth interviews who had: a recent CVD event (≤ 3 months); documented referral to OCR; low SES (Medicaid eligible, or in the top quartile of area deprivation index); those who attended ≥ 1 session of OCR and those who did not. Semi-structured interviews were recorded and transcribed verbatim. Codes were identified using a phenomenological approach guided by the COM-B model.Results:Participants (N=26) were 54% women, 58% Black, with mean age of 67.1 (12.7 years). Barriers and facilitators identified fit the COM-B model.Capabilitythemes included knowledge and awareness of OCR. OCR attendees (n=12) recalled discussing OCR, the benefits, and their physicians encouraging participation pre-discharge. Non-attendees (N=14) reported no, or very little knowledge about OCR, or weak recommendations by their physician.Opportunitythemes included social support from caregivers/family, peers, and their healthcare team. OCR attendees described a strong support network of caregivers who helped with logistics and motivation to participate, wanting to be with peers, and outreach of the healthcare team after discharge. Non-attendees described lack of social support, logistical barriers, and no outreach.Motivationthemes reflected the strong belief in the benefits of CR to improve physical and mental health, quality of life, and prevent future events among attendees. Non-attendees generally lacked a perceived need for OCR particularly if they had returned to baseline after their CVD event.Conclusions:Non-attenders of CR were distinguishable from attendees using the COM-B model, which can be used to guide intervention development. Our findings support a multi-level strategy that includes tailored education, social support, motivational enhancement, implemented by a trained health navigator, to overcome barriers to CR attendance among patients with low SES.

Circulation, Volume 150, Issue Suppl_1, Page A4124323-A4124323, November 12, 2024. Background:Atrial fibrillation (AF) is a leading cause of stroke. However, predictors of stroke after AF ablation have not been well clarified, therefore, evidences of anticoagulation therapy after the procedure have been limited. Although left atrial low-voltage areas (LVAs) reflects atrial cardiomyopathy, which is a potential cause of thromboembolism, there are few reports of an association between LVAs and stroke. The purpose of this study was to investigate the association between atrial cardiomyopathy assessed by LVAs and stroke in patients undergoing AF ablation.Methods:The study design was a single center, retrospective observational study. This study included 1,486 (age, 68 ± 10 years; female, 501 [34%]; persistent AF, 905 [61%]) consecutive patients who underwent initial AF ablation from December 2014 to March 2022. The definition of LVAs were areas with a bipolar voltage of

Circulation, Volume 150, Issue Suppl_1, Page A4130314-A4130314, November 12, 2024. Background:Diets high in sodium and low in potassium are associated with increased blood pressure level but associations with cardiovascular disease (CVD) remain controversial. Few studies have evaluated this relationship among Hispanic/Latino adults.Objective:To assess whether dietary sodium and potassium are associated with incident CVD among diverse US Hispanics/Latino adults.Methods:The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) is a cohort of 16,415 self-identifying Hispanic/Latino adults aged 18-74 four US urban communities in 2008-2011 (visit 1; V1). V1 included a comprehensive examination with in-person measurement of health information and interviewer administered questionnaires. Dietary sodium (mg/day) and potassium (mg/day) intakes were assessed from the average of two 24-hour dietary recall surveys administered by bilingual registered dietitians. CVD events occurring from V1 through 2019 were adjudicated by an expert panel of clinicians. We used Poisson regression to determine the association (incidence rate ratio, IRR) between sodium, potassium, and the sodium-to-potassium ratio, with CVD, using time to CVD as an offset. Models accounted for HCHS/SOL complex survey design and were adjusted for demographic, including Hispanic/Latino background, socioeconomic, and behavioral factors along with energy consumption, body mass index, cholesterol, and family history of CVD.Results:Among 15,291 participants without self-reported CVD at V1, mean age was 40 years, with 53% female. Mean daily intakes of sodium and potassium were 3,040 mg/day and 2,422 mg/day, respectively. Molar ratio of sodium to potassium was 1.33. Over 9.7 years of follow-up, there were 311 CVD events (2.0 events per 1,000 person years, 95% CI: 1.6, 2.5). In adjusted models, nutrients were associated with increased risk of CVD: by 17% for each 1g/day increment of sodium (IRR: 1.17, 95% CI: 1.03, 1.33); by 29% for each 1g/day decrement of potassium (IRR: 1.29, 95% CI: 1.01, 1.64); and by 112% for each 0.5 molar increment of sodium to potassium ratio (IRR: 2.12, 95% CI: 1.13, 4.11).Conclusions:In a large diverse sample of Hispanic/Latino adults, high dietary sodium and low dietary potassium were independently associated with an increased risk of CVD. Results underscore the importance of intensifying public health interventions to improve nutrient quality, by reducing dietary sodium and increasing dietary potassium consumption as a means of preventing CVD.
