J Card Fail 2024; 30:14-22. [PMID: 37543186 PMCID: PMC10838360 DOI: 10.1016/j.cardfail.2023.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 05/30/2023] [Accepted: 07/13/2023] [Indexed: 08/07/2023]
Abstract
BACKGROUND This study compared the predictive value of the race-independent creatinine- and cystatin C-based estimated glomerular filtration rate (eGFRcr-cys) and the race-dependent creatinine-based eGFR (eGFRcr) for incident heart failure (HF). METHODS This study combined the participant-level data from ARIC (Atherosclerosis Risk in Communities) (visit 4) and MESA (Multi-Ethnic Study of Atherosclerosis) (visit 1) to calculate eGFRcr-cys and eGFRcr. The primary outcome of the study was adjudicated incident HF over a follow-up period of 10 years. Multivariable Cox models were used to assess the risk of incident HF with the quartiles of eGFRcr-cys and eGFRcr. RESULTS Among 15,615 individuals (median age: 62 [57-68] years; 55.0% females; 23.9% Black), the median eGFRcr-cys and eGFRcr were 91.4 (79.4, 102.0) mL/min/1.73m2 and 84.7 (72.0, 94.7) mL/min/1.73m2, respectively. Compared with the fourth quartile of eGFRcr-cys, the hazard ratio for incident HF was 1.02 (95% CI:0.80-1.30) in the third quartile, 1.02 (95% CI:0.80-1.30) in the second quartile, and 1.47 (95% CI:1.16-1.86) in the first quartile. Compared with the 4th quartile of the eGFRcr, the risk of incident HF was similar in the 3rd (HRadj:0.90 [95% CI:0.73-1.12]), 2nd (HRadj: 0.96 [95% CI:0.77-1.20]), and 1st (HRadj:1.15 [95% CI:0.93-1.44]) quartiles. C-statistics were similar for the multivariable-adjusted Cox models for incident HF using eGFRcr (0.80 [0.79-0.81]) and eGFRcr-cys (0.80 [0.79-0.82]). CONCLUSION The eGFRcr and eGFRcr-cys had comparable predictive values for incident HF.

High-Dose Inhaled Nitric Oxide in Acute Hypoxemic Respiratory Failure Due to COVID-19: A Multicenter Phase II Trial. Am J Respir Crit Care Med 2023; 208:1293-1304. [PMID: 37774011 PMCID: PMC10765403 DOI: 10.1164/rccm.202304-0637oc] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 09/28/2023] [Indexed: 10/01/2023] Open
Abstract
Rationale: The effects of high-dose inhaled nitric oxide on hypoxemia in coronavirus disease (COVID-19) acute respiratory failure are unknown. Objectives: The primary outcome was the change in arterial oxygenation (PaO2/FiO2) at 48 hours. The secondary outcomes included: time to reach a PaO2/FiO2.300mmHg for at least 24 hours, the proportion of participants with a PaO2/FiO2.300mmHg at 28 days, and survival at 28 and at 90 days. Methods: Mechanically ventilated adults with COVID-19 pneumonia were enrolled in a phase II, multicenter, single-blind, randomized controlled parallel-arm trial. Participants in the intervention arm received inhaled nitric oxide at 80 ppm for 48 hours, compared with the control group receiving usual care (without placebo). Measurements and Main Results: A total of 193 participants were included in the modified intention-to-treat analysis. The mean change in PaO2/FiO2 ratio at 48 hours was 28.3mmHg in the intervention group and 21.4mmHg in the control group (mean difference, 39.1mmHg; 95% credible interval [CrI], 18.1 to 60.3). The mean time to reach a PaO2/FiO2.300mmHg in the interventional group was 8.7 days, compared with 8.4 days for the control group (mean difference, 0.44; 95% CrI, 23.63 to 4.53). At 28 days, the proportion of participants attaining a PaO2/FiO2.300mmHg was 27.7% in the inhaled nitric oxide group and 17.2% in the control subjects (risk ratio, 2.03; 95% CrI, 1.11 to 3.86). Duration of ventilation and mortality at 28 and 90 days did not differ. No serious adverse events were reported. Conclusions: The use of high-dose inhaled nitric oxide resulted in an improvement of PaO2/FiO2 at 48 hours compared with usual care in adults with acute hypoxemic respiratory failure due to COVID-19.

Abstract
Background Marfan syndrome is a potentially fatal inherited autosomal dominant condition impacting the cardiovascular and the skeletal system with an estimated 25% cases caused by sporadic genetic variations. Given the genetic inheritance pattern, an autopsy of probands with Marfan syndrome-associated mortality is critical to establish the phenotypic expression and clinical implications of the particular genetic variant, especially for first-degree relatives. We present the findings of a Marfan syndrome proband decedent presenting with sudden onset abdominal pain and unexplained retroperitoneal abdominal hemorrhage. Methods An autopsy was performed to inform the blood relatives of the phenotypic expression and penetrance of the potentially heritable condition. A clinical laboratory improvement amendment (CLIA)-certified clinical grade genetic sequencing was performed to identify pathogenic variants in genes associated with aortopathy. Results The autopsy showed intra-abdominal and retroperitoneal hemorrhage due to infarction of the right kidney caused by dissection of the right renal artery. Genetic testing identified a heterozygous pathogenic FBN1 gene variant. The specific variant is FBN1 NM_000138.4 c.2953G > A p.(Gly985Arg). Conclusions We report a case of a previously undiagnosed Marfan syndrome death due to a de novo FBN1 variant, c.2953G > A.

Sex-Associated Differences in the Clinical Outcomes of Left Ventricular Assist Device Recipients: Insights From Interagency Registry for Mechanically Assisted Circulatory Support. Circ Heart Fail 2023; 16:e010189. [PMID: 37232167 PMCID: PMC10421565 DOI: 10.1161/circheartfailure.122.010189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Accepted: 02/20/2023] [Indexed: 05/27/2023]
Abstract
BACKGROUND Sex-associated differences in clinical outcomes among left ventricular assist device recipients in the United States have been recognized. However, an investigation of the social and clinical determinants of sex-associated differences is lacking. METHODS Left ventricular assist device receiving patients enrolled in Interagency Registry for Mechanically Assisted Circulatory Support between 2005 and 2017 were included. The primary outcome was all-cause mortality. Secondary outcomes included heart transplantation and postimplantation adverse event rates. The cohort was stratified by the social subgroup of race and ethnicity (non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, and Hispanic), and clinical subgroups of device strategy (destination therapy, bridge to transplant, and bridge to candidacy), and implantation center volume (low [≤20 implants/y], medium [21-30 implants/y], and high [>30 implants/y]). A multivariable-adjusted Cox proportional hazard model was used to assess the risk of death and heart transplantation with prespecified interaction testing. Poisson regression was used to estimate adverse events by sex across the various subgroups. RESULTS Among 18 525 patients, there were 3968 (21.4%) females. Compared with their male counterparts, Hispanic (adjusted hazard ratio [HRadj], 1.75 [1.23-2.47]) females had the highest risk of death followed by non-Hispanic White females (HRadj, 1.15 [1.07-1.25]; Pinteraction=0.02). Hispanic (HRadj, 0.60 [0.40-0.89]) females had the lowest cumulative incidence of heart transplantation followed by non-Hispanic Black females (HRadj, 0.76 [0.67-0.86]), and non-Hispanic White females (HRadj, 0.88 [0.80-0.96]) compared with their male counterparts (Pinteraction<0.001). Compared with their male counterparts, females on the bridge to candidacy strategy (HRadj, 1.32 [1.18-1.48]) had the highest risk of death (Pinteraction=0.01). The risk of death (Pinteraction=0.44) and cumulative incidence of heart transplantation (Pinteraction=0.40) did not vary by sex in the center volume subgroup. A higher incidence rate of adverse events after left ventricular assist device implantation was also seen in females compared with the males, overall, and across all subgroups. CONCLUSIONS Among left ventricular assist device recipients, the risk of death, the cumulative incidence of heart transplantation, and adverse events differ by sex across the social and clinical subgroups.

Complications Associated With Transesophageal Echocardiography in Transcatheter Structural Cardiac Interventions. J Am Soc Echocardiogr 2023; 36:381-390. [PMID: 36610496 PMCID: PMC10079559 DOI: 10.1016/j.echo.2022.12.023] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 12/22/2022] [Accepted: 12/30/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND Transesophageal echocardiograms (TEEs) performed during transcatheter structural cardiac interventions may result in greater complications than those performed in the nonoperative setting or even those performed during cardiac surgery. However, there are limited data on complications associated with TEE during these procedures. We evaluated the prevalence of major complications among these patients in the United States. METHODS A retrospective cohort study was conducted using an electronic health record database (TriNetX Research Network) from large academic medical centers across the United States for patients undergoing TEE during transcatheter structural interventions from January 2012 to January 2022. Using the American Society of Echocardiography-endorsed International Statistical Classification of Diseases and Related Health Problems Clinical Modifications (10th edition) codes, patients undergoing TEE during a transcatheter structural cardiac intervention, including transaortic, mitral or tricuspid valve repair, left atrial appendage occlusion, atrial septal defect closure, patent foramen ovale closure, and paravalvular leak repair, were identified. The primary outcome was major complications within 72 hours of the procedure (composite of bleeding and esophageal and upper respiratory tract injury). The secondary aim was the frequency of major complications, death, or cardiac arrest within 72 hours in patients who completed intraoperative TEE during surgical valve replacement. RESULTS Among 12,043 adult patients (mean age, 74 years old; 42% female) undergoing TEE for transcatheter structural cardiac interventions, 429 (3.6%) patients had a major complication. Complication frequency was higher in patients on anticoagulation or antiplatelet therapy compared with those not on therapy (3.9% vs 0.5%; risk ratio [RR] = 8.09, P < .001). Compared with those patients <65 years of age, patients ≥65 years of age had a higher frequency of major complications (3.9% vs 2.2%; RR = 1.75, P < .001). Complication frequency was similar among male and female patients (3.5% vs 3.7%; RR = 0.96, P = .67). Among 28,848 patients who completed surgical valve replacement with TEE guidance, 728 (2.5%) experienced a major complication. CONCLUSIONS This study found that more than 3% of patients undergoing TEE during transcatheter structural cardiac interventions have a major complication, which is more common among those on anticoagulant or antiplatelet therapy or who are elderly. With a shift of poor surgical candidates to less invasive percutaneous procedures, the future of TEE-guided procedures relies on comprehensive risk discussion and updating practices beyond conventional methods to minimize risk for TEE-related complications.

Associations of atrial natriuretic peptide with measures of insulin and adipose depots. Physiol Rep 2023; 11:e15625.

Abstract
Low concentrations of natriuretic peptides (NPs) have been associated with greater risk for Type 2 diabetes (T2D). African American individuals (AA) have lower NP levels and are disproportionately burdened by T2D. The purpose of this study was to test the hypothesis that higher post-challenge insulin in AA adults is associated with lower plasma N-terminal pro-atrial natriuretic peptide (NT-proANP). A secondary purpose was to explore associations between NT-proANP and adipose depots. Participants were 112 AA and European American (EA) adult men and women. Measures of insulin were obtained from an oral glucose tolerance test and hyperinsulinemic-euglycemic glucose clamp. Total and regional adipose depots were measured from DXA and MRI. Multiple linear regression analysis was used to assess associations of NT-proANP with measures of insulin and adipose depots. Lower NT-proANP concentrations in AA participants was not independent of 30-min insulin area under the curve (AUC). NT-proANP was inversely associated with 30-min insulin AUC in AA participants, and with fasting insulin and HOMA-IR in EA participants. Thigh subcutaneous adipose tissue and perimuscular adipose tissue were positively associated with NT-proANP in EA participants. Higher post-challenge insulin may contribute to lower ANP concentrations in AA adults.

Abstract
Objective This study assessed cardiovascular health (CVH) in young adults using the 2022 AHA Life's Essential 8 (LE8) score and compared it with the Life's Simple 7 (LS7) score. Methods Individuals aged 18 to 44 years without a history of cardiovascular disease in the National Health and Nutrition Examination Survey (NHANES) cycles were included. Data from 2007-2008 to 2017-2018 were combined to create 3 groups (2007-2010, 2011-2014, and 2015-2018) for analysis. The LE8 score and its components were computed in the overall population and stratified by sex and race/ethnicity. Trends for the LE8 score were analyzed using adjusted linear regression models. Results Among 12,197 young adults, representing an estimated 89.4 million individuals, from the NHANES 2007-2018, the CVH in the overall population and across all subgroups was stable (Ptrend >0.05). The blood lipid score improved across all subgroups (Ptrend:<0.05). The mean LE8 score was 69.2±0.3. Females (71.4±0.4) had better CVH compared with males (67.2±0.4). Non-Hispanic Black individuals (65.1± 0.3) had the lowest CVH compared with Non-Hispanic White individuals (69.9±0.5), Mexican American individuals (67.3±0.3), and other race individuals (71.2±0.4). Of the 46.1 million individuals categorized as intermediate CVH by the LS7 score, 8.1 million (17.6%) and 2.3 million (5.0%) were reclassified to poor and ideal CVH by the LE8 score, respectively. Of the 40.1 million individuals categorized as ideal CVH by the LS7 score, 18.9 million (47.1%) and 0.1 million (0.2%) were reclassified to poor CVH and intermediate CVH by the LE8 score, respectively. Conclusion Among US young adults, there has been no improvement in CVH over the last decade with notable sex and race/ethnicity-associated differences in the LE8 score. Nearly 1 in 4 young adults had ideal CVH using the LE8 score compared with 1 in 2 individuals using the LS7 score.

Abstract
Background:
Polygenic risk scores (PRS) have shown promise in complementing existing clinical risk factors and improving early diagnosis of cardiovascular disease. Recently, several studies have developed PRS for blood pressure traits; however, few have examined to what extent these PRS predict antihypertensive (AHT) efficacy.
Hypothesis:
We hypothesize that applying a systolic blood pressure (SBP) PRS developed and trained in multi-ancestral observational studies will predict response to chlorthalidone (CHL), as well as non-response to AHT treatment (apparent treatment resistant hypertension, aTRH), among African Americans (AA).
Methods:
We applied an optimized multi-ancestry PRS generated in a pooled Trans-Omics for Precision Medicine (TOPMed) cohort of >21,000 adults for SBP (PRS
SBP
) to 4,297 AA Genetics of Hypertension Associated Treatment (GenHAT) participants randomized to CHL as part of the Antihypertensive and Lipid Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) with genome wide association study data. We then used linear regression to test the association of PRS
SBP
quintiles with CHL response (6 month BP - baseline BP) adjusting for age, sex, genetic ancestry, and baseline SBP. For the analysis of aTRH, cases were defined as individuals (a) treated with 3 different AHT classes, with average BP ≥140/90 mmHg at year 3 follow-up or (b) ≥4 AHT classes regardless of BP (cases, n=286). Treated controls were defined as individuals with BP <140/90 mmHg and on trial drug monotherapy at year 3 (n=2,391). Logistic regression models adjusting for age, sex, and genetic ancestry were used to calculate the odds ratio for aTRH comparing the highest and lowest quintile (Q5 and Q1, respectively).
Results:
The PRS
SBP
was associated with reduced SBP response in Q5 (-5.01 [-6.15, -3.87] mmHg) versus Q1 (-8.24 [-9.39, -7.09] mmHg) and Q2 (-7.25 [-8.39, -6.11] mmHg). In regard to aTRH, Q5 was nominally associated with higher odds of aTRH compared to Q1 (1.48 [1.00, 2.20]).
Conclusions:
We found that a general SBP PRS was associated with BP response in AAs from GenHAT. On average, a greater SBP reduction was found in participants at low genetic risk (Q1 or Q2) compared to the high risk (Q5) taking the same AHT. Similarly, when compared to participants in the bottom 20% of the distribution, those in the top 20% had increased odds of aTRH. Additional work using the PRS
SBP
in other ancestral populations, as well as developing novel AHT class treatment response PRS, is warranted and in progress to determine whether we can identify individuals who would benefit the most from specific AHT classes.

Temporal lipid profiling in the progression from acute to chronic heart failure in mice and ischemic human hearts. Atherosclerosis 2022; 363:30-41.

Abstract
BACKGROUND AND AIMS Myocardial infarction (MI) is a leading cause of heart failure (HF). After MI, lipids undergo several phasic changes implicated in cardiac repair if inflammation resolves on time. However, if inflammation continues, that leads to end stage HF progression and development. Numerous studies have analyzed the traditional risk factors; however, temporal lipidomics data for human and animal models are limited. Thus, we aimed to obtain sequential lipid profiling from acute to chronic HF. METHODS Here, we report the comprehensive lipidome of the hearts from diseased and healthy subjects. To induce heart failure in mice, we used a non-reperfused model of coronary ligation, and MI was confirmed by echocardiography and histology, then temporal kinetics of lipids in different tissues (heart, spleen, kidney), and plasma was quantitated from heart failure mice and compared with naïve controls. For lipid analysis in mouse and human samples, untargeted liquid chromatography-linear trap quadrupole orbitrap mass spectrometry (LC-LTQ-Orbitrap MS) was performed. RESULTS In humans, multivariate analysis revealed distinct cardiac lipid profiles between healthy and ischemic subjects, with 16 lipid species significantly downregulated by 5-fold, mainly phosphatidylethanolamines (PE), in the ischemic heart. In contrast, PE levels were markedly increased in mouse tissues and plasma in chronic MI, indicating possible cardiac remodeling. Further, fold change analysis revealed site-specific lipid biomarkers for acute and chronic HF. A significant decrease in sulfatides (SHexCer (34:1; 2O)) and sphingomyelins (SM (d18:1/16:0)) was observed in mouse tissues and plasma in chronic HF. CONCLUSIONS Overall, a significant decreased lipidome in human ischemic LV and differential lipid metabolites in the transition of acute to chronic HF with inter-organ communication could provide novel insights into targeting integrative pathways for the early diagnosis or development of novel therapeutics to delay/prevent HF.

Association of a Multiancestry Genome-Wide Blood Pressure Polygenic Risk Score With Adverse Cardiovascular Events. CIRCULATION. GENOMIC AND PRECISION MEDICINE 2022; 15:e003946.

Abstract
BACKGROUND Traditional cardiovascular risk factors and the underlying genetic risk of elevated blood pressure (BP) determine an individual's composite risk of developing adverse cardiovascular events. We sought to evaluate the relative contributions of the traditional cardiovascular risk factors to the development of adverse cardiovascular events in the context of varying BP genetic risk profiles. METHODS Genome-wide polygenic risk score (PRS) was computed using multiancestry genome-wide association estimates among US adults who underwent whole-genome sequencing in the Trans-Omics for Precision program. Individuals were stratified into high, intermediate, and low genetic risk groups (>80th, 20-80th, and <20th centiles of systolic BP [SBP] PRS). Based on the ACC/AHA Pooled Cohort Equations, participants were stratified into low and high (10 year-atherosclerotic cardiovascular disease [CVD] risk: <10% or ≥10%) cardiovascular risk factor profile groups. The primary study outcome was incident cardiovascular event (composite of incident heart failure, incident stroke, and incident coronary heart disease). RESULTS Among 21 897 US adults (median age: 56 years; 56.0% women; 35.8% non-White race/ethnicity), 1 SD increase in the SBP PRS, computed using 1.08 million variants, was associated with SBP (β: 4.39 [95% CI, 4.13-4.65]) and hypertension (odds ratio, 1.50 [95% CI, 1.46-1.55]), respectively. This association was robustly seen across racial/ethnic groups. Each SD increase in SBP PRS was associated with a higher risk of the incident CVD (multivariable-adjusted hazards ratio, 1.07 [95% CI, 1.04-1.10]) after controlling for ACC/AHA Pooled Cohort Equations risk scores. Among individuals with a high SBP PRS, low atherosclerotic CVD risk was associated with a 58% lower hazard for incident CVD (multivariable-adjusted hazards ratio, 0.42 [95% CI, 0.36-0.50]) compared to those with high atherosclerotic CVD risk. A similar pattern was noted in intermediate and low genetic risk groups. CONCLUSIONS In a multiancestry cohort of >21 000 US adults, genome-wide SBP PRS was associated with BP traits and adverse cardiovascular events. Adequate control of modifiable cardiovascular risk factors may reduce the predisposition to adverse cardiovascular events among those with a high SBP PRS.

Arachidonate 5-lipoxygenase is essential for biosynthesis of specialized pro-resolving mediators and cardiac repair in heart failure. Am J Physiol Heart Circ Physiol 2022; 323:H721-H737. [PMID: 36018758 PMCID: PMC9529265 DOI: 10.1152/ajpheart.00115.2022] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 08/17/2022] [Accepted: 08/19/2022] [Indexed: 11/22/2022]
Abstract
Arachidonate 5-lipoxygenase (ALOX5)-derived leukotrienes are primary signals of leukocyte activation and inflammation in response to ischemic cardiac injury (MI; myocardial infarction). Using risk-free male C57BL/6J and ALOX5-null mice (8-12 wk), we quantitated leukocytes and ALOX5-derived bioactive lipids of the infarcted left ventricle (LV) and spleen to measure the physiological inflammation and cardiac repair. Our results showed that ALOX5 endogenously generates specialized pro-resolving mediators (SPMs) that facilitate cardiac repair post-MI. Deficiency of ALOX5 leads to increase in cyclooxygenase gene expression, 6-keto prostaglandin F1α, and delayed neutrophil clearance with signs of unresolved inflammation post-MI. Consequently, ALOX5 deficiency impaired the resolution of inflammation and cardiac repair, including increased myocardium rupture post-MI in acute heart failure. On-time ALOX5 activation is critical for leukocyte clearance from the infarcted heart, indicating an essential role of ALOX5 in the resolution of inflammation. In addition, to balance the inflammatory responses, ALOX5 is also necessary for fibroblast signaling, as the ALOX5-deficient fibroblast are prone to fibroblast-to-myofibroblast differentiation leading to defective scar formation in post-MI cardiac repair. Consistent with these findings, ALOX5-null mice showed an overly inflammatory response, defective fibrotic signaling, and unresolved inflammation. These findings are indicative of a critical role of ALOX5 in myocardium healing, inflammation-resolution signaling, cardiac repair, and fibroblast pathophysiology.NEW & NOTEWORTHY Arachidonate 5-lipoxygenase (ALOX5) is critical in synthesizing specialized pro-resolving mediators that facilitate cardiac repair after cardiac injury. Thus, ALOX5 orchestrates the overlapping phases of inflammation and resolution to facilitate myocardium healing in cardiac repair postmyocardial infarction.

Risk of Postdischarge Bleeding From Dual Antiplatelet Therapy After Percutaneous Coronary Intervention Among US Black and White Adults. J Am Heart Assoc 2022; 11:e024412. [PMID: 36073636 PMCID: PMC9683679 DOI: 10.1161/jaha.121.024412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 07/07/2022] [Indexed: 11/16/2022]
Abstract
Background Dual antiplatelet therapy after percutaneous coronary intervention reduces myocardial infarctions but increases bleeding. The risk of bleeding may be higher among Black patients for unknown reasons. Bleeding risk scores have not been validated among Black patients. We assessed the difference in bleeding risk between Black and White patients along with the performance of the Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Anti Platelet Therapy, Patterns of Nonadherence to Antiplatelet Regimens in Stented Patients, and Academic Research Consortium for High Bleeding Risk scores among both groups. Methods and Results This was a single-center prospective study of patients who underwent percutaneous coronary intervention (2014-2019) and were followed for 1 year. The outcome was postdischarge Bleeding Academic Research Consortium 2 to 5 bleeding. Incidence rates were reported. Cox proportional hazards models measured the effect of self-reported Black race on bleeding and determined the predictors of bleeding among 19 a priori variables. The 3 risk scores were assessed among Black and White patients separately using the Harrell concordance index. Of 1529 included patients, 342 (22.4%) self-reported as being Black race. Unadjusted bleeding rates were 22.7 per 100 person-years among Black patients versus 16.3 among White patients (hazard ratio, 1.41 [95% CI, 1.00-2.00], P=0.052). Predictors of bleeding were age, glomerular filtration rate <30 mL/min per 1.73 m2, prior bleeding, ticagrelor or prasugrel use, and anticoagulant use. Among Black and White patients, respectively, the C-indexes were the following: 0.644 versus 0.600 for Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Anti Platelet Therapy (P<0.001 for both), 0.620 versus 0.612 for Patterns of Nonadherence to Antiplatelet Regimens in Stented Patients (P=0.003 and P<0.001, respectively), and 0.600 versus 0.598 for Academic Research Consortium for High Bleeding Risk (P=0.006 and P<0.001, respectively). Conclusions The risk of dual antiplatelet therapy-associated postdischarge Bleeding Academic Research Consortium 2 to 5 bleeding was not significantly different between self-reported Black and White patients. Bleeding risk scores performed similarly among both groups.

Abstract
Background Corin enzyme contributes to the processing of inactive natriuretic peptides to bioactive hormones. In Black individuals, Corin gene variants (rs111253292 [Q568P] and rs75770792 [T555I]) have been previously reported to have a modest association with blood pressure (BP) and hypertension. Methods and Results We evaluated the association of Corin genotype with BP traits, prevalent hypertension, and incident hypertension among self‐identified 11 322 Black Americans in the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study and the JHS (Jackson Heart Study) using multivariable‐adjusted regression modeling. Multivariable‐adjusted genotype‐stratified differences in NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) and BNP (B‐type natriuretic peptide) levels were assessed. Genotype‐stratified NPPA and NPPB expression differences in healthy organ donor left atrial and left ventricular heart tissue (N=15) were also examined. The rs111253292 genotype was not associated with systolic BP (β±SE, 0.42±0.58; −1.24±0.82), diastolic BP (0.51±0.33; −0.41±0.46), mean arterial pressure (0.48±0.38; −0.68±0.51), and prevalent hypertension (odds ratio [OR], 0.93 [95% CI, 0.80–1.09]; OR, 0.79 [95% CI, 0.61–1.01]) in both REGARDS and JHS, respectively. The rs75770792 genotype was not associated with systolic BP (0.48±0.58; −1.26±0.81), diastolic BP (0.52±0.33; −0.33±0.45), mean arterial pressure (0.50±0.38; −0.63±0.50), and prevalent hypertension (OR, 1.02 [95% CI, 0.84–1.23]; OR, 0.87 [95% CI, 0.67–1.13]) in both cohorts, respectively. The Corin genotype was also not associated with incident hypertension (OR, 1.35 [95% CI, 0.94–1.93]; OR, 0.95 [95% CI, 0.64–1.39]) in the study cohorts. The NT‐proBNP levels in REGARDS and BNP levels in JHS were similar between the Corin genotype groups. In heart tissue, the NPPA and NPPB expression was similar between the genotype groups. Conclusions Corin gene variants observed more commonly in Black individuals are not associated with differences in NP expression, circulating NP levels, and BP or hypertension as previously reported in candidate gene studies. Understanding the genetic determinants of complex cardiovascular traits in underrepresented populations requires further evaluation.

Abstract
IMPORTANCE A genetic variant in the TTR gene (rs76992529; Val122Ile), present more commonly in individuals with African ancestry (population frequency: 3%-4%), causes misfolding of the tetrameric transthyretin protein complex that accumulates as extracellular amyloid fibrils and results in hereditary transthyretin amyloidosis. OBJECTIVE To estimate the association of the amyloidogenic Val122Ile TTR variant with the risk of heart failure and mortality in a large, geographically diverse cohort of Black individuals. DESIGN, SETTING, AND PARTICIPANTS Retrospective population-based cohort study of 7514 self-identified Black individuals living in the US participating in the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study with genetic data available and without heart failure at baseline. The participants were enrolled at the baseline visit (2003-2007). The end of follow-up for the majority of outcomes was on December 31, 2018. All-cause mortality data were available through December 31, 2020. EXPOSURES TTR Val122Ile (rs76992529) genotype. MAIN OUTCOME AND MEASURES The primary outcome was incident heart failure (first hospitalization for heart failure or death due to heart failure). The secondary outcomes were heart failure mortality, cardiovascular mortality, and all-cause mortality. The multivariable Cox proportional hazards regression analyses were adjusted for genetic ancestry and demographic, clinical, and social factors. RESULTS Among 7514 Black participants (median age, 64 years [IQR, 57-70 years]; 61% women), the population frequency of the TTR Val122Ile variant was 3.1% (232 variant carriers and 7282 noncarriers). During a median follow-up of 11.1 years (IQR, 5.9-13.5 years), incident heart failure occurred in 535 individuals (34 variant carriers and 501 noncarriers) and the incidence of heart failure was 15.64 per 1000 person-years among variant carriers vs 7.16 per 1000 person-years among noncarriers (adjusted hazard ratio [HR], 2.43 [95% CI, 1.71-3.46]; P < .001). Deaths due to heart failure occurred in 141 individuals (13 variant carriers and 128 noncarriers) and the incidence of heart failure mortality was 6.11 per 1000 person-years among variant carriers vs 1.85 per 1000 person-years among noncarriers (adjusted HR, 4.19 [95% CI, 2.33-7.54]; P < .001). Deaths due to cardiovascular causes occurred in 793 individuals (34 variant carriers and 759 noncarriers) and the incidence of cardiovascular death was 15.18 per 1000 person-years among variant carriers vs 10.61 per 1000 person-years among noncarriers (adjusted HR, 1.69 [95% CI, 1.19-2.39]; P = .003). Deaths due to any cause occurred in 2715 individuals (100 variant carriers and 2615 noncarriers) and the incidence of all-cause mortality was 41.46 per 1000 person-years among variant carriers vs 33.94 per 1000 person-years among noncarriers (adjusted HR, 1.46 [95% CI, 1.19-1.78]; P < .001). There was no significant interaction between TTR variant carrier status and sex on incident heart failure and the secondary outcomes. CONCLUSIONS AND RELEVANCE Among a cohort of Black individuals living in the US, being a carrier of the TTR Val122Ile variant was significantly associated with an increased risk of heart failure.

Abstract
BACKGROUND Black individuals have high incident diabetes risk, despite having paradoxically lower triglyceride and higher HDL (high-density lipoprotein) cholesterol levels. The basis of this is poorly understood. We evaluated the participants of SPRINT (Systolic Blood Pressure Intervention Trial) to assess the association of estimated European genetic ancestry with the risk of incident diabetes in self-identified Black individuals. METHODS Self-identified non-Hispanic Black SPRINT participants free of diabetes at baseline were included. Black participants were stratified into tertiles (T1-T3) of European ancestry proportions estimated using 106 biallelic ancestry informative genetic markers. The multivariable-adjusted association of European ancestry proportion with indices of baseline metabolic syndrome (ie, fasting plasma glucose, triglycerides, HDL cholesterol, body mass index, and blood pressure) was assessed. Multivariable-adjusted Cox regression determined the risk of incident diabetes (fasting plasma glucose ≥126 mg/dL or self-reported diabetes treatment) across tertiles of European ancestry proportion. RESULTS Among 2466 Black SPRINT participants, a higher European ancestry proportion was independently associated with higher baseline triglyceride and lower HDL cholesterol levels (P<0.001 for both). European ancestry proportion was not associated with baseline fasting plasma glucose, body mass index, and blood pressure (P>0.05). Compared with the first tertile, those in the second (hazard ratio, 0.64 [95% CI, 0.45-0.90]) and third tertiles (hazard ratio, 0.61 [95% CI, 0.44-0.89]) of the European ancestry proportion had a lower risk of incident diabetes. A 5% point higher European ancestry was associated with a 29% lower risk of incident diabetes (hazard ratio, 0.71 [95% CI, 0.55-0.93]). There was no evidence of a differential association between the European ancestry proportion tertiles and incident diabetes between those randomized to intensive versus standard blood pressure treatment. CONCLUSIONS The higher risk of incident diabetes in Black individuals may have genetic determinants in addition to adverse social factors. Further research may help understand the interplay between biological and social determinants of cardiometabolic health in Black individuals.

Abstract
BACKGROUND The burden of insulin resistance (IR) among young American adults has not been previously assessed. We evaluated (1) the prevalence and trends of IR and cardiometabolic risk factors and (2) the association between measures of adiposity and IR among adults 18 to 44 years of age without diabetes and preexisting cardiovascular disease. METHODS Cross-sectional survey data from six consecutive National Health and Nutrition Examination Survey (2007-2008 to 2017-2018) cycles were analyzed. IR was defined by the homeostatic model assessment for IR (HOMA-IR) of ≥2.5. The temporal trends of IR, cardiometabolic risk factors, and the relationship between IR and measures of adiposity were assessed using multivariable-adjusted regression models. RESULTS Among 6247 young adults 18 to 44 years of age, the prevalence of IR was 44.8% (95% CI: 42.0%-47.6%) in 2007-2010 and 40.3% (95% CI: 36.4%-44.2%) in 2015-2018 (P for trend = 0.07). There was a modest association of HOMA-IR with higher body mass index (BMI), waist circumference, total lean fat mass, and total and localized fat mass (all Ps < 0.001). Participants with IR had a higher prevalence of hypertension [31.3% (95% CI: 29.2%-33.5%) vs 14.7% (95% CI: 13.2%-16.2%)], hypercholesterolemia [16.0% (95% CI: 12.4%-19.5%) vs 7.0% (95% CI: 5.8%-8.5%)], obesity [56.6% (95% CI: 53.9%-59.3%) vs 14.7% (95% CI: 13.0%-16.5%)], and poor physical activity levels [18.3% (95% CI: 16.4%-20.2%) vs 11.7% (95%CI: 10.3-13.1%)] compared to participants without IR (all Ps < 0.05). CONCLUSIONS Four-in-10 young American adults have IR, which occurs in a cluster with cardiometabolic risk factors. Nearly half of young adults with IR are nonobese. Screening efforts for IR irrespective of BMI may be required.

Relation of Abdominal Obesity to Risk of Atrial Fibrillation (From the Reasons for Geographic and Racial Differences in Stroke [REGARDS] Study). Am J Cardiol 2022; 162:116-121. [PMID: 34903337 DOI: 10.1016/j.amjcard.2021.08.065] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 08/23/2021] [Accepted: 08/24/2021] [Indexed: 11/29/2022]
Abstract
Our knowledge of the association between abdominal obesity (AO) and the risk of atrial fibrillation (AF) after adjusting for body mass index (BMI) is limited. We included 11,617 Black and White participants (mean age 63.0 ± 8.4 years) from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) national cohort study who were free of AF at baseline. A multivariable logistic regression model was used to estimate the odds ratio (OR) with 95% confidence interval (CI) of incident AF associated with AO. We also evaluated the association between waist circumference (WC) and incident AF. Over a median follow-up of 9.4 years, 999 participants developed AF. AO was associated with an increased risk of AF in a multivariable model adjusted for sociodemographic, lifestyle, and cardiovascular risk factors (OR 1.43, 95% CI 1.24 to 1.65, p <0.001). The association was attenuated after adjusting for BMI (OR 1.13, 95% CI 0.95 to 1.35, p = 0.16). There was no evidence of interaction between AO and incident AF by age category (age >65 vs age ≤65), gender, race, obesity, or BMI category. Conversely, a 10cm increase in WC was associated with a higher incidence of AF after controlling for BMI (OR 1.18 95% CI 1.09 to 1.29, p <0.001), in both nonobese (OR 1.14, 95% CI 1.03 to 1.28, p = 0.02) and obese (OR 1.26, 95% CI 1.11 to 1.42, p <0.001) people. In conclusion, there was an association between AO and incident AF, but the association was weakened after adjusting for BMI. There was a significant association between WC and incident AF, after taking other AF risk factors and BMI into account. WC is a potentially modifiable risk factor for AF, and further research is warranted to explore the effect of decreasing WC on the population AF burden.

Abstract
Background:
Among patients receiving percutaneous coronary intervention (PCI), the role of a genotype-guided approach for antiplatelet therapy compared with usual care is unclear. We conducted a Bayesian analysis of the entire TAILOR-PCI (Tailored Antiplatelet Initiation to Lessen Outcomes Due to Decreased Clopidogrel Response After Percutaneous Coronary Intervention) randomized clinical trial population to evaluate the effect of the genotype-guided antiplatelet therapy post-PCI compared with the usual care on the risk of major adverse cardiovascular events (MACE).
Methods:
The primary outcome for our study was the composite of MACE (myocardial infarction, stroke, and cardiovascular death). Secondary outcomes included cardiovascular death, stroke, myocardial infarction, stent thrombosis, and major/minor bleeding. Bayesian modeling was used to estimate the probability of clinical benefit of genotype-guided therapy using (1) noninformative priors (ie, analyzing the TAILOR-PCI trial) and (2) informative priors derived from the ADAPT, POPular Genetics, IAC-PCI, and PHARMCLO trials (ie, analyzing TAILOR-PCI trial in the context of prior evidence). Risk ratio (RR: ratio of cumulative outcome incidence between genotype-guided and conventional therapy group) and 95% credible interval (CrI) were estimated for the study outcomes, and probability estimates for RR <1 were computed.
Results:
Using noninformative priors, in TAILOR-PCI the RR for MACE was 0.78 (95% CrI, 0.55–1.07) in genotype-guided therapy after PCI, and the probability of RR <1 was 94%. Using noninformative priors, the probability of RR <1 for cardiovascular death (RR, 0.95 [95% CrI, 0.52–1.74]), stroke (RR, 0.68 [95% CrI, 0.44–1.06]), myocardial infarction (RR, 0.84 [95% CrI, 0.37–1.89]), stent thrombosis (RR, 0.75 [95% CrI, 0.37–1.45]), and major or minor bleeding (RR, 1.22 [95% CrI, 0.84–1.77]) were 57%, 96%, 67%, 81%, and 15%, respectively. Using informative priors, the posterior probability of RR <1 for MACE, from genotype-guided therapy, was 99% (RR, 0.69 [95% CrI, 0.57–0.84]). Using informative priors, the posterior probability of RR <1 for cardiovascular death (RR, 0.86 [95% CrI, 0.61–1.19]), stroke (RR, 0.69 [95% CrI, 0.48–0.99]), myocardial infarction (RR:0.56 [95% CrI, 0.40–0.78]), stent thrombosis (RR, 0.59 [95% CrI, 0.38–0.94]), and major or minor bleeding (RR, 0.84 [95% CrI, 0.70–0.99]) were 81%, 99%, 99%, 99%, and 99%, respectively.
Conclusions:
Bayesian analysis of the TAILOR-PCI trial provides clinically meaningful data on the posterior probability of reducing MACE using genotype-guided P2Y

Abstract
Sphingosine-1-phosphate (S1P) is a bioactive mediator in inflammation. Dysregulated S1P is demonstrated as a cause of heart failure (HF). However, the time-dependent and integrative role of S1P interaction with receptors in HF is unclear after myocardial infarction (MI). In this study, the sphingolipid mediators were quantified in ischemic human hearts. We also measured the time kinetics of these mediators post-MI in murine spleen and heart as an integrative approach to understand the interaction of S1P and respective S1P receptors in the transition of acute (AHF) to chronic HF (CHF). Risk-free 8-12 wk male C57BL/6 mice were subjected to MI surgery, and MI was confirmed by echocardiography and histology. Mass spectrometry was used to quantify sphingolipids in plasma, infarcted heart, spleen of mice, and ischemic and healthy human heart. The physiological cardiac repair was observed in mice with a notable increase of S1P quantity (pmol/g) in the heart and spleen significantly reduced in patients with ischemic HF. The circulating murine S1P levels were increased during AHF and CHF despite lowered substrate in CHF. The S1PR1 receptor expression was observed to coincide with the respective S1P quantity in mice and human hearts. Furthermore, selective S1P1 agonist limited inflammatory markers CCL2 and TNF-α and accelerated reparative markers ARG-1 and YM-1 in macrophages in the presence of Kdo2-Lipid A (KLA; potent inflammatory stimulant). This report demonstrated the importance of S1P/S1PR1 signaling in physiological inflammation during cardiac repair in mice. Alteration in these axes may serve as the signs of pathological remodeling in patients with ischemia.NEW & NOTEWORTHY Previous studies indicate that sphingosine-1-phosphate (S1P) has some role in cardiovascular disease. This study adds quantitative and integrative systems-based approaches that are necessary for discovery and bedside translation. Here, we quantitated sphinganine, sphingosine, sphingosine-1-phosphate (S1P) in mice and human cardiac pathobiology. Interorgan S1P quantity and respective systems-based receptor activation suggest cardiac repair after myocardial infarction. Thus, S1P serves as a therapeutic target for cardiac protection in clinical translation.

Abstract
OBJECTIVE To evaluate the contemporary geographic trends in cardiovascular health in the United States and its relationship with geographic distribution of cardiovascular mortality. METHODS By use of a retrospective cross-sectional design, the 2011-2017 Behavioral Risk Factor Surveillance System (BRFSS) was queried to determine the age-adjusted prevalence of cardiovascular health index (CVHI) metrics (sum of ideal blood pressure, blood glucose concentration, lipid levels, body mass index, smoking, physical activity, and diet). Cardiovascular health was estimated as both continuous (0 to 7 points) and categorical (ideal, intermediate, poor) variables from the BRFSS. Age-adjusted cardiovascular mortality for 2017 was obtained from the Centers for Disease Control and Prevention WONDER database. RESULTS Among 1,362,529 American adult participants of the BRFSS 2011-2017 and all American residents in 2017, the CVHI score increased from 3.89±0.004 in 2011 to 3.96±0.005 in 2017 (Ptrend<.001) nationally, with modest improvement across all regions (Ptrend<.05 for all). Ideal cardiovascular health prevalence improved in the northeastern (Ptrend=.03) and southern regions (Ptrend=.002). In 2017, the prevalence of coronary heart disease (6.8%; 95% CI, 6.5% to 7.1%) and stroke (3.7%; 95% CI, 3.4% to 3.9%) was highest in the southern region. The CVHI score (3.81±0.01) and the prevalence of ideal cardiovascular health (12.2%; 95% CI, 11.7% to 12.7%) were lowest in the southern United States. This corresponded to the higher cardiovascular mortality in the southern region (233.0 [95% CI, 232.2- to 33.8] per 100,000 persons). CONCLUSION Despite a modest improvement in CVHI, only 1 in 6 Americans has ideal cardiovascular health with significant geographic differences. These differences correlate with the geographic distribution of cardiovascular mortality. An urgent unmet need exists to mitigate the geographic disparities in cardiovascular morbidity and mortality.

Abstract
Children and adolescents account for ~ 13% of total COVID-19 cases in the United States. However, little is known about the nature of the illness in children. The reopening of schools underlines the importance of understanding the epidemiology of pediatric COVID-19 infections. We sought to assess the clinical characteristics and outcomes in pediatric COVID-19 patients. We conducted a retrospective cross-sectional analysis of pediatric patients diagnosed with COVID-19 from healthcare organizations in the United States. The study outcomes (hospitalization, mechanical ventilation, critical care) were assessed using logistic regression. The subgroups of sex and race were compared after propensity score matching. Among 12,306 children with lab-confirmed COVID-19, 16.5% presented with respiratory symptoms (cough, dyspnea), 13.9% had gastrointestinal symptoms (nausea, vomiting, diarrhea, abdominal pain), 8.1% had dermatological symptoms (rash), 4.8% had neurological (headache), and 18.8% had other non-specific symptoms (fever, malaise, myalgia, arthralgia and disturbances of smell or taste). In the study cohort, the hospitalization frequency was 5.3%, with 17.6% needing critical care services and 4.1% requiring mechanical ventilation. Following propensity score matching, the risk of all outcomes was similar between males and females. Following propensity score matching, the risk of hospitalization was greater in non-Hispanic Black (RR 1.97 [95% CI 1.49–2.61]) and Hispanic children (RR 1.31 [95% CI 1.03–1.78]) compared with non-Hispanic Whites. In the pediatric population infected with COVID-19, a substantial proportion were hospitalized due to the illness and developed adverse clinical outcomes.

Geographic Inequalities in Cardiovascular Mortality in the United States: 1999 to 2018. Mayo Clin Proc 2021; 96:1218-1228. [PMID: 33840523 DOI: 10.1016/j.mayocp.2020.08.036] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 08/24/2020] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To evaluate the trends in cardiovascular, ischemic heart disease (IHD), stroke, and heart failure mortality in the stroke belt in comparison with the rest of the United States. PATIENTS AND METHODS We evaluated the nationwide mortality data of all Americans from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database from 1999 to 2018. Cause-specific deaths were identified in the stroke belt and nonstroke belt populations using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes. The relative percentage gap was estimated as the absolute difference computed relative to nonstroke belt mortality. Piecewise linear regression and age-period-cohort modeling were used to assess, respectively, the trends and to forecast mortality across the 2 regions. RESULTS The cardiovascular mortality rate (per 100,000 persons) was 288.3 (95% CI, 288.0 to 288.6; 3,684,273 deaths) in the stroke belt region and 251.2 (95% CI, 251.0 to 251.3; 13,296,164 deaths) in the nonstroke belt region. In the stroke belt region, age-adjusted mortality rates due to all cardiovascular causes (average annual percentage change [AAPC] in mortality rates, -2.4; 95% CI, -2.8 to -2.0), IHD (AAPC, -3.8; 95% CI, -4.2 to -3.5), and stroke (AAPC, -2.8; 95% CI, -3.4 to -2.1) declined from 1999 to 2018. A similar decline in cardiovascular (AAPC, -2.5; 95% CI, -3.0 to -2.0), IHD (AAPC, -4.0; 95% CI, -4.3 to -3.7), and stroke (AAPC, -2.9; 95% CI, -3.2 to -2.2) mortality was seen in the nonstroke belt region. There was no overall change in heart failure mortality in both regions (PAAPC>.05). The cardiovascular mortality gap was 11.8% in 1999 and 15.9% in 2018, with a modest reduction in absolute mortality rate difference (~7 deaths per 100,000 persons). These patterns were consistent across subgroups of age, sex, race, and urbanization status. An estimated 101,953 additional cardiovascular deaths need to be prevented from 2020 to 2025 in the stroke belt to ameliorate the gap between the 2 regions. CONCLUSION Despite the overall decline, substantial geographic disparities in cardiovascular mortality persist. Novel approaches are needed to attenuate the long-standing geographic inequalities in cardiovascular mortality in the United States, which are projected to increase.

Chronobiology of Natriuretic Peptides and Blood Pressure in Lean and Obese Individuals. J Am Coll Cardiol 2021; 77:2291-2303. [PMID: 33958126 DOI: 10.1016/j.jacc.2021.03.291] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/16/2021] [Accepted: 03/16/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Diurnal variation of natriuretic peptide (NP) levels and its relationship with 24-h blood pressure (BP) rhythm has not been established. Obese individuals have a relative NP deficiency and disturbed BP rhythmicity. OBJECTIVES This clinical trial evaluated the diurnal rhythmicity of NPs (B-type natriuretic peptide [BNP], mid-regional pro-atrial natriuretic peptide [MR-proANP], N-terminal pro-B-type natriuretic peptide [NT-proBNP]) and the relationship of NP rhythm with 24-h BP rhythm in healthy lean and obese individuals. METHODS On the background of a standardized diet, healthy, normotensive, lean (body mass index 18.5 to 25 kg/m2) and obese (body mass index 30 to 45 kg/m2) individuals, age 18 to 40 years, underwent 24-h inpatient protocol involving ambulatory BP monitoring starting 24 h prior to the visit, controlled light intensity, and repeated blood draws for assessment of analytes. Cosinor analysis of normalized NP levels (normalized to 24-h mean value) was conducted to assess the diurnal NP rhythm and its relationship with systolic BP. RESULTS Among 52 participants screened, 40 participants (18 lean, 22 obese; 50% women; 65% Black) completed the study. The median range spread (percentage difference between the minimum and maximum values) over 24 h for MR-proANP, BNP, and NT-proBNP levels was 72.0% (interquartile range [IQR]: 50.9% to 119.6%), 75.5% (IQR: 50.7% to 106.8%), and 135.0% (IQR: 66.3% to 270.4%), respectively. A cosine wave-shaped 24-h oscillation of normalized NP levels (BNP, MR-proANP, and NT-proBNP) was noted both in lean and obese individuals (prhythmicity <0.05 for all). A larger phase difference between MR-proANP BP rhythm (-4.9 h vs. -0.7 h) and BNP BP rhythm (-3.3 h vs. -0.9 h) was seen in obese compared with lean individuals. CONCLUSIONS This human physiological trial elucidates evidence of diurnal NP rhythmicity and the presence of an NP-BP rhythm axis. There exists a misalignment of the NP-BP diurnal rhythm in the obese, which may contribute to the disturbed diurnal BP pattern observed among obese individuals.

Abstract
BACKGROUND Despite numerous advances in the understanding of the pathophysiology, progression, and management of acute respiratory failure (ARF) and ARDS, limited contemporary data are available on the mortality burden of ARF and ARDS in the United States. RESEARCH QUESTION What are the contemporary trends and geographic variation in ARF and ARDS-related mortality in the United States? STUDY DESIGN AND METHODS A retrospective analysis of the National Center for Health Statistics' nationwide mortality data was conducted to assess the ARF and ARDS-related mortality trends from 2014 through 2018 and the geographic distribution of ARF and ARDS-related deaths in 2018 for all American residents. Piecewise linear regression was used to evaluate the trends in age-adjusted mortality rates (AAMRs) in the overall population and various demographic subgroups of age, sex, race, urbanization, and region. RESULTS Among 1,434,349 ARF-related deaths and 52,958 ARDS-related deaths during the study period, the AAMR was highest in older individuals (≥ 65 years), non-Hispanic Black people, and those living in the nonmetropolitan region. The AAMR for ARF-related deaths (per 100,000 people) increased from 74.9 (95% CI, 74.6-75.2) in 2014 to 85.6 (95% CI, 85.3-85.9) in 2018 (annual percentage change [APC], 3.4 [95% CI, 2.2-4.6]; Ptrend = .003). The AAMR (per 100,000 people) for ARDS-related deaths was 3.2 (95% CI, 3.2-3.3) in 2014 and 3.0 (95% CI, 3.0-3.1 in 2018; APC, -0.9 [95% CI, -5.4 to 3.8]; Ptrend = .56). The observed increase in rates for ARF mortality was consistent across the subgroups of age, sex, race or ethnicity, urbanization status, and geographical region (Ptrend < .05 for all). The AAMR (per 100,000 people) for ARF (91.3 [95% CI, 90.8-91.8]) and ARDS-related mortality (3.3 [95% CI, 3.2-3.4]) in 2018 were highest in the South. INTERPRETATION The ARF-related mortality increased at approximately 3.4% annually, and ARDS-related mortality showed a lack of decline in the last 5 years. These data contextualize important health information to guide priorities for research, clinical care, and policy, especially during the coronavirus disease 2019 pandemic in the United States.

Abstract
Objective There has been a substantial decline in patients presenting for emergent and routine cardiovascular care in the United States after the onset of the coronavirus disease 2019 (COVID-19) pandemic. We sought to assess the risk of adverse clinical outcomes among patients undergoing coronary artery bypass graft (CABG) surgery during the 2020 COVID-19 pandemic period and compare the risks with those undergoing CABG before the pandemic in the year 2019. Methods A retrospective cross-sectional analysis of the TriNetX Research Network database was performed. Patients undergoing CABG between January 20, 2019, and September 15, 2019, contributed to the 2019 cohort, and those undergoing CABG between January 20, 2020, and September 15, 2020, contributed to the 2020 cohort. Propensity-score matching was performed, and the odds of mortality, acute kidney injury, stroke, acute respiratory distress syndrome, and mechanical ventilation occurring by 30 days were evaluated. Results The number of patients undergoing CABG in 2020 declined by 35.5% from 5534 patients in 2019 to 3569 patients in 2020. After propensity-score matching, 3569 patient pairs were identified in the 2019 and the 2020 cohorts. Compared with those undergoing CABG in 2019, the odds of mortality by 30 days were 0.96 (95% confidence interval [CI], 0.69-1.33; P = .80) in those undergoing CABG in 2020. The odds for stroke (odds ratio [OR], 1.201; 95% CI, 0.96-1.39), acute kidney injury (OR, 0.76; 95% CI, 0.59-1.08), acute respiratory distress syndrome (OR, 1.01; 95% CI, 0.60-2.42), and mechanical ventilation (OR, 1.11; 95% CI, 0.94-1.30) were similar between the 2 cohorts. Conclusions The number of patients undergoing CABG in 2020 has substantially declined compared with 2019. Similar odds of adverse clinical outcomes were seen among patients undergoing CABG in the setting of COVID-19 compared with those in 2019.

Abstract
Background Obese patients have lower NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) levels. The prognostic implications of achieving NT‐proBNP levels ≤1000 pg/mL in obese patients with heart failure (HF) receiving biomarker‐guided therapy are not completely known. We evaluated the prognostic implications of obesity and having NT‐proBNP levels (≤1000 pg/mL) in the GUIDE‐IT (Guiding Evidence‐Based Therapy Using Biomarker‐Intensified Treatment in HF) trial participants. Methods and Results The risk of adverse cardiovascular events (HF hospitalization or cardiovascular mortality) was assessed using multivariable‐adjusted Cox proportional hazard models based on having NT‐proBNP ≤1000 pg/mL (taken as a time‐varying covariate), stratified by obesity status. The study outcome was also assessed on the basis of the body mass index at baseline. The predictive ability of NT‐proBNP for adverse cardiovascular events was assessed using the likelihood ratio test. Compared with nonobese patients, obese patients were mostly younger, Black race, and more likely to be women. NT‐proBNP levels were 59.0% (95% CI, 39.5%–83.5%) lower among obese individuals. The risk of adverse cardiovascular events was lower in obese (hazard ratio [HR], 0.48; 95% CI, 0.29–0.59) and nonobese (HR, 0.32; 95% CI, 0.19–0.57) patients with HF who had NT‐proBNP levels ≤1000 pg/mL, compared with those who did not. There was no interaction between obesity and having NT‐proBNP ≤1000 pg/mL on the study outcome (P>0.10). Obese patients had a greater risk of developing adverse cardiovascular events (HR, 1.39; 95% CI, 1.01–1.90) compared with nonobese patients. NT‐proBNP was the strongest predictor of adverse cardiovascular event risk in both obese and nonobese patients. Conclusions On‐treatment NT‐proBNP level ≤1000 pg/mL has favorable prognostic implications, irrespective of obesity status. NT‐proBNP levels were the strongest predictor of cardiovascular events in both obese and nonobese individuals in this trial.

Abstract
Aims We sought to compare the generalizability and prognostic implications of heart failure with preserved ejection fraction (HFpEF) scores (HFA‐PEFF and H2FPEF score) in Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) and Phosphodiesterase‐5 Inhibition to Improve Clinical Status and Exercise Capacity in Heart Failure with Preserved Ejection Fraction (RELAX) trial participants and matched controls from the Atherosclerosis Risk in Community (ARIC) study. Methods and results Based on the respective scores, the study participants from the TOPCAT (N = 356), RELAX (N = 216), and ARIC (N = 379) studies were categorized as having a low, intermediate, or high likelihood of HFpEF. Age, sex, and race matched controls free of cardiovascular disease who had unexplained dyspnoea were used to evaluate the diagnostic performance. The prognostic value of scores was assessed using multivariable‐adjusted Cox regression analyses. The median HFA‐PEFF scores in the TOPCAT, RELAX, and ARIC studies were 5.0 [interquartile range (IQR): 5.0–6.0], 4.0 (IQR: 2.0–4.0), and 3.0 (IQR: 2.0–4.0), respectively. The median H2FPEF scores in the three studies were 5.5 (IQR: 4.0–7.0), 6.0 (IQR: 4.0–7.0), and 3.0 (IQR: 2.0–5.0), respectively. A low HFA‐PEFF and H2FPEF score can rule out HFpEF with high sensitivity (99.5% and 99.6%, respectively) and negative predictive value (95.7% and 98.3%, respectively). A high HFA‐PEFF and H2FPEF score can rule‐in HFpEF with good specificity (82.8% and 95.6%, respectively) and positive predictive value (79.9% and 90.4%, respectively). Among TOPCAT participants, the hazard for adverse cardiovascular events per point increase in HFA‐PEFF and H2FPEF score was 1.26 (95% confidence interval: 0.98–1.63) and 1.01 (95% confidence interval: 0.88–1.15), respectively. A higher H2FPEF score was associated with lower peak oxygen intake in RELAX trial participants (adjusted P = 0.01). Conclusions The HFA‐PEFF and the H2FPEF scores are reliable diagnostic tools for HFpEF. The prognostic utility of HFpEF scores requires further validation in larger rigorously phenotyped populations.

Abstract
Supplemental Digital Content is available in the text. The 2017 American College of Cardiology/American Heart Association high blood pressure (BP) guidelines recommend risk assessment of atherosclerotic cardiovascular disease to inform hypertension treatment in adults with elevated BP or low-risk stage I hypertension. The use of coronary artery calcium (CAC) score to guide hypertension therapy has not been adequately evaluated. Participants free of cardiovascular disease were pooled from Multi-Ethnic Study of Atherosclerosis, Coronary Artery Risk Development in Young Adults, and Jackson Heart Study. The risk for incident cardiovascular events (heart failure, stroke, coronary heart disease), by CAC status (CAC-0 or CAC>0) and BP treatment group was assessed using multivariable-adjusted Cox regression. The 10-year number needed to treat to prevent a single cardiovascular event was also estimated. This study included 6461 participants (median age 53 years; 53.3% women; 32.3% Black participants). Over a median follow-up of 8.5 years, 347 incident cardiovascular events occurred. Compared with those with normal BP, the risk of incident cardiovascular event was higher among those with elevated BP/low-risk stage I hypertension and CAC>0 (hazard ratio, 2.4 [95% CI, 1.7–3.4]) and high-risk stage I/stage II hypertension (BP, 140–160/80–100 mm Hg) with CAC>0 (hazard ratio, 2.9 [95% CI, 2.1–4.0]). A similar pattern was evident across racial subgroups and for individual study outcomes. Among those with CAC-0, the 10-year number needed to treat was 160 for elevated BP/low-risk stage I hypertension and 44 for high-risk stage I or stage II hypertension (BP, 140–160/80–100 mm Hg). Among those with CAC>0, the 10-year number needed to treat was 36 and 22, respectively. Utilization of the CAC score may guide the initiation of hypertension therapy and preventive approaches to personalize cardiovascular risk reduction among individuals where the current guidelines do not recommend treatment.

Abstract
OBJECTIVE To evaluate the nationwide trends in mortality due to mitral regurgitation (MR) among American adults from 1999 to 2018. PATIENTS AND METHODS Trends in mortality due to MR were assessed using retrospective cross-sectional analyses of nationwide mortality data from death certificates of all American residents between January 1, 1999, and December 31, 2018, using the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Piecewise linear regression was used to evaluate the trends in the overall population and in subgroups. RESULTS Among 45,982 deaths due to MR during the study period, higher mortality rates were seen in older White females from the western United States. In 1999, the crude and age-adjusted mortality rates were 27.4 (95% CI, 26.3 to 28.4) and 27.5 (95% CI, 26.4 to 28.5) per 1,000,000 persons, respectively. By 2018, these rates declined to 18.0 (95% CI, 17.3 to 18.7) and 17.7 (95% CI, 17.0 to 18.4) per 1,000,000 persons, respectively (P<.001 for trend for both). Crude mortality rates declined from 1999 to 2012 (annual percentage change [APC], -4.1 (95% CI, -4.6 to -3.6) but then increased after 2012 (APC, 2.6 [95% CI, 0.8 to 4.4; P<.001 for change in trend]). The age-adjusted mortality rates declined from 1999 to 2012 (APC, -3.9 [95% CI, -4.4 to -3.4]) but subsequently increased after 2012 (APC, 1.4 [95% CI, -0.4 to 3.2; P<.001 for change in trend]). The observed decrease was consistent across age, sex, race, geographic region, and urbanization subgroups (P<.05 for all). CONCLUSION Mortality due to MR in American adults declined at an annual rate of approximately 4% until 2012 and has since then increased by about 1.5% annually. These mortality trends warrant further investigation.

Objective To evaluate the race-stratified state-level prevalence of health determinants and the racial disparities in coronavirus disease 2019 (COVID-19) cumulative incidence and mortality in the United States. Patients and Methods The age-adjusted race-stratified prevalence of comorbidities (hypertension, diabetes, dyslipidemia, and obesity), preexisting medical conditions (pulmonary disease, heart disease, stroke, kidney disease, and malignant neoplasm), poor health behaviors (smoking, alcohol abuse, and physical inactivity), and adverse socioeconomic factors (education, household income, and health insurance) was computed in 435,139 American adult participants from the 2017 Behavioral Risk Factor Surveillance System survey. Correlation was assessed between health determinants and the race-stratified COVID-19 crude mortality rate and infection-fatality ratio computed from respective state public health departments in 47 states. Results Blacks had a higher prevalence of comorbidities (63.3%; 95% CI, 62.4% to 64.2% vs 55.1%; 95% CI, 54.7% to 55.5%) and adverse socioeconomic factors (47.0%; 95% CI, 46.0% to 47.9% vs 30.9%; 95% CI, 30.6% to 31.3%) than did whites. The prevalence of preexisting medical conditions was similar in blacks (30.4%; 95% CI, 28.8% to 32.1%) and whites (30.8%; 95% CI, 30.2% to 31.4%). The prevalence of poor health behaviors was higher in whites (57.2%; 95% CI, 56.3% to 58.0%) than in blacks (50.2%; 95% CI,46.2% to 54.2%). Comorbidities and adverse socioeconomic factors were highest in the southern region, and poor health behaviors were highest in the western region. The cumulative incidence rate (per 100,000 persons) was 3-fold higher in blacks (1546.4) than in whites (540.4). The crude mortality rate (per 100,000 persons) was 2-fold higher in blacks (83.2) than in whites (33.2). However, the infection-fatality ratio (per 100 cases) was similar in whites (6.2) and blacks (5.4). Within racial groups, the geographic distribution of health determinants did not correlate with the state-level COVID-19 mortality and infection-fatality ratio (P>.05 for all). Conclusion Racial disparities in COVID-19 are largely driven by the higher cumulative incidence of infection in blacks. There is a discordance between the geographic dispersion of COVID-19 mortality and the regional distribution of health determinants.

Prevalence, Awareness, Treatment, and Poor Control of Hypertension Among Young American Adults: Race-Stratified Analysis of the National Health and Nutrition Examination Survey. Mayo Clin Proc 2020; 95:1390-1403. [PMID: 32622447 DOI: 10.1016/j.mayocp.2020.01.041] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/25/2019] [Revised: 01/25/2020] [Accepted: 01/31/2020] [Indexed: 12/24/2022]
Abstract
OBJECTIVE To evaluate the race-stratified trends for prevalence, awareness, treatment, and control of hypertension in young American adults aged 18 to 44 years. PATIENTS AND METHODS The National Health and Nutrition Examination Survey data from 2005-2016 for adults aged 18 to 44 years was used to calculate age-adjusted (using 2005, 2010, and 2015 US Census population proportions) weighted trends in prevalence, awareness, treatment, and control of hypertension among non-Hispanic white, non-Hispanic black, and Mexican-American participants as per the 2017 American College of Cardiology/American Heart Association guidelines. Trends were estimated by logistic regression models including demographic, socioeconomic, health care access, and Bonferroni correction for multiple comparisons as covariates. RESULTS Among 15,171 young American adults, stable trends for the prevalence, awareness, treatment, and control of hypertension was seen in all racial groups (Plinear trend>.05 for all). The prevalence from 2013 to 2016 was highest in non-Hispanic blacks (30.7%; 95% CI, 27.3 to 34.0%), followed by non-Hispanic whites (21.9%; 95% CI, 19.6 to 24.1%), and Mexican Americans (21.9%; 95% CI, 18.6 to 25.1%). The awareness was stable at ∼43.2% in non-Hispanic blacks, ∼34.8% in non-Hispanic whites, and ∼28.4% in Mexican Americans from 2005 to 2008 through 2013 to 2016. The stable treatment rates at nearly 34.4%, 23.7%, and 20.6%, were seen in non-Hispanic black, non-Hispanic white, and Mexican-Americans, respectively. The optimal control of hypertension was seen in 14.5% (95% CI, 12.1 to 17.0%) non-Hispanic blacks, 12.2% (95% CI, 10.3 to 14.0%) non-Hispanic whites, and 10.3% (95% CI, 7.1 to 13.5%) Mexican Americans from 2013 to 2016. CONCLUSION Nearly one in every three non-Hispanic young black and one in every five young Mexican American and non-Hispanic white adults have hypertension. Our race-stratified analyses highlight the categorical need to improve the abysmal control of hypertension which is approximately 1 in 10 young adults.

Clinical, Demographic, and Imaging Correlates of Anemia in Heart Failure With Preserved Ejection Fraction (from the RELAX Trial). Am J Cardiol 2020; 125:1870-1878. [PMID: 32307089 DOI: 10.1016/j.amjcard.2020.03.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Revised: 03/01/2020] [Accepted: 03/03/2020] [Indexed: 01/14/2023]
Abstract
Anemia is a commonly occurring comorbidity among patients of heart failure with preserved ejection fraction (HFpEF) but limited data exists on the cardiovascular phenotype of anemia in HFpEF. We sought to characterize the clinical features, exercise capacity, and outcomes in patients with HFpEF to elucidate the phenotype and pathophysiology of anemia in HFpEF. Post hoc analyses of participants enrolled in the RELAX (Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in Diastolic Heart Failure) trial was performed. Anemia was defined as hemoglobin <13 g/dL in men and <12 g/dL in women. Multivariate adjusted regression modeling was done to assess for differences in peak oxygen uptake. Adjusted hazard ratios were generated to assess difference in hospitalization events using a Cox proportional hazards model. Anemic HFpEF patients were more likely to be older, male, and have worse renal function (p <0.05 for all). N-terminal pro-B-type natriuretic peptide, troponin I, pro-collagen III N-terminal peptide, C-telopeptide for type I collagen, uric acid, cystatin-c, and galectin-3 (p <0.05 for all) levels were higher in anemic HFpEF patients. In adjusted models, anemic HFpEF patients had worse exercise capacity (peak oxygen uptake: 11.3 vs 12.1 mL/kg/min; p = 0.004). The hazard for cardiac or renal cause of hospitalization in those with anemia was 2.0 (95% confidence interval: 0.9 to 4.3). Anemic HFpEF patients have worse exercise capacity and are more likely to be hospitalized. A better understanding of the physiologic phenotypes of HFpEF patients may allow for greater personalization of treatment and prognostication in HFpEF patients.

Implications of Atrial Fibrillation Among Patients With Atherosclerotic Cardiovascular Disease Undergoing Noncardiac Surgery. Am J Cardiol 2020; 125:1836-1844. [PMID: 32331712 DOI: 10.1016/j.amjcard.2020.03.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 03/08/2020] [Accepted: 03/10/2020] [Indexed: 11/25/2022]
Abstract
Atrial fibrillation (AF) is a common perioperative arrhythmia. However, its occurrence and implications remain poorly defined in the setting of noncardiac procedures. We sought to define the incidence, prevalence, and prognostic implications of AF among patients with atherosclerotic cardiovascular disease (ASCVD) undergoing noncardiac surgery. Using a previously validated approach that employed unique patient-linked variables in the New York State Inpatient Database from January 1, 2012, to December 31, 2014, the frequency of new-onset and pre-existing AF was determined in adults with ASCVD aged ≥18 years undergoing noncardiac surgery. The secondary outcomes were stroke within 1 month and all-cause mortality. Using multivariable logistic regression models, the factors and outcomes associated with new-onset AF after noncardiac surgery were assessed. Nine surgical subgroups of major noncardiac surgery served as exposure. A total of 184,775 patients were identified during the study period. Age ≥65, anemia, history of heart failure, valvular heart disease, and thoracic surgery were predictors of new-onset AF after noncardiac surgery. Among 3,806 patients (2.5%) developed new-onset AF and 31,603 (17.5%) patient had pre-existing AF. After multivariable-adjusted modeling, new-onset AF was associated with increased odds of stroke within 1 month (odds ratio: 1.31, 95% confidence interval: 1.12 to 1.53; p < 0.001)], mortality (odds ratio: 3.74; 95% confidence interval: 3.30 to 4.24; p < 0.001) and longer length of stay in the hospital (10 days; interquartile range: 6 to 16 days; p < 0.001). New-onset AF portends a poor prognosis in patients with ASCVD undergoing noncardiac surgeries. The risk profile of patients that develop new-onset AF differs across patient phenotypes and by surgical procedure.

Abstract
We evaluated the impact of intensive blood pressure control on the incidence of new-onset atrial fibrillation/flutter (AF) and the prognostic implications of preexisting and new-onset AF in SPRINT (Systolic Blood Pressure Intervention Trial) participants. New-onset AF was defined as occurrence of AF in 12-lead electrocardiograms after randomization in participants free of AF at baseline. Poisson regression modeling was used to calculate incident rates of new-onset AF. Multivariable-adjusted Cox proportional hazard models were used to evaluate the risk of adverse cardiovascular events (composite of myocardial infarction, non-myocardial infarction acute coronary syndrome, stroke, heart failure, or cardiovascular death). In 9327 participants, 8.45% had preexisting AF, and 1.65% had new-onset AF. The incidence of new-onset AF was 4.53 per 1000-person years, with similar rates in the standard and intensive treatment arms (4.95 versus 4.11 per 1000-person years; adjusted P=0.14). Participants with preexisting AF (adjusted hazard ratio, 1.83 [95% CI, 1.46-2.31]; P<0.001) and new-onset AF (adjusted hazard ratio, 2.45 [95% CI, 1.58-3.80]; P<0.001) had a greater risk for development of adverse cardiovascular events compared with those with no AF. Participants with preexisting AF who achieved blood pressure <120/80 mm Hg at 3 months continued have a poor prognosis (adjusted hazard ratio, 1.88 [95% CI, 1.32-2.70]; P=0.001) compared with those with no AF. Intensive blood pressure control does not diminish the incidence of new-onset AF in an older, high-risk, nondiabetic population. Both preexisting and new-onset AF have adverse prognostic implications. In participants with preexisting AF, residual cardiovascular risk is evident even with on-treatment blood pressure <120/80 mm Hg.

Abstract
Introduction:
Improvements in therapy and prevention have led to declining cardiovascular mortality in the United States, but it is not clear whether these improvements have narrowed geographic disparities in cardiovascular outcomes. We sought to compare mortality due to cardiovascular disease, heart failure, stroke, and ischemic heart disease in the stroke belt cluster of 11 states versus the rest of the United States.
Methods:
A retrospective cross-sectional analysis of the CDC WONDER database was done to evaluate the nationwide mortality trends derived from the death certificates of all American residents from 1999 to 2017. Mortality trends for death due to heart failure, stroke, ischemic heart disease or any cardiovascular cause, were identified in the stroke belt and non-stroke belt populations using ICD-10 codes. Piecewise linear regression was used to assess the change in mortality trends.
Results:
Among 16,111,775 deaths due to cardiovascular causes during the study period, the age-adjusted mortality rates (AAMR) were highest among non-Hispanic Black, males from non-metropolitan areas, living in the stroke belt. In the stroke belt, AAMR due to all cardiovascular causes [Average Annual Percentage Change (AAPC): -2.5 (95% CI:-2.9 to -2.0); p<0.001], stroke [AAPC: -2.9 (95% CI: -3.7 to -2.1); p<0.001] and ischemic heart disease [AAPC: -3.9 (95% CI: -4.3 to -3.5); p<0.001] declined from 1999 to 2017. Similarly, a decrease in cardiovascular [AAPC: -2.6 (95% CI:-3.1 to -2.1); p<0.001], stroke [AAPC:-2.9 (95% CI: -3.2 to -2.2); p<0.001] and ischemic heart disease [AAPC: -4.1 (95% CI: -4.5 to -3.6); p<0.001] mortality was seen in the non-stroke belt region from 1999 to 2017. There was no overall change in heart failure mortality in either regions (p for AAPC >0.05). The gap in age-adjusted mortality estimates for cardiovascular cause of death was 11.8% in 1999 and was 16% in 2017 across the two regions (
Figure 1
). The mortality gaps were persistent across sub-groups of age, sex, race, and level of urbanization.
Conclusions:
Despite the overall decline in cardiovascular mortality, significant geographic disparities in cardiovascular mortality persist. Preventive efforts targeting risk factors and improved disease management may attenuate the longstanding geographical heterogeneity in cardiovascular mortality.
