The American Heart Association at 100: A Century of Scientific Progress and the Future of Cardiovascular Science: A Presidential Advisory From the American Heart Association.

In 1924, the founders of the American Heart Association (AHA) envisioned an international society focused on the heart and aimed at facilitating research, disseminating information, increasing public awareness, and developing public health policy related to heart disease. This presidential advisory provides a comprehensive review of the past century of cardiovascular and stroke science, with a focus on the AHA's contributions, as well as informed speculation about the future of cardiovascular science into the next century of the organization's history. The AHA is a leader in fundamental, translational, clinical, and population science, and it promotes the concept of the "learning health system," in which a continuous cycle of evidence-based practice leads to practice-based evidence, permitting an iterative refinement in clinical evidence and care. This advisory presents the AHA's journey over the past century from instituting professional membership to establishing extraordinary research funding programs; translating evidence to practice through clinical practice guidelines; affecting systems of care through quality programs, certification, and implementation; leading important advocacy efforts at the federal, state and local levels; and building global coalitions around cardiovascular and stroke science and public health. Recognizing an exciting potential future for science and medicine, the advisory offers a vision for even greater impact for the AHA's second century in its continued mission to be a relentless force for longer, healthier lives.

Clinical Outcomes in Hypertensive Emergency: A Systematic Review and Meta-Analysis.

Background To study the prevalence and types of hypertension-mediated organ damage and the prognosis of patients presenting to the emergency department (ED) with hypertensive emergencies. Methods and Results PubMed was queried from inception through November 30, 2021. Studies were included if they reported the prevalence or prognosis of hypertensive emergencies in patients presenting to the ED. Studies reporting data on hypertensive emergencies in other departments were excluded. The extracted data were arcsine transformed and pooled using a random-effects model. Fifteen studies (n=4370 patients) were included. Pooled analysis demonstrates that the prevalence of hypertensive emergencies was 0.5% (95% CI, 0.40%-0.70%) in all patients presenting to ED and 35.9% (95% CI, 26.7%-45.5%) among patients presenting in ED with hypertensive crisis. Ischemic stroke (28.1% [95% CI, 18.7%-38.6%]) was the most prevalent hypertension-mediated organ damage, followed by pulmonary edema/acute heart failure (24.1% [95% CI, 19.0%-29.7%]), hemorrhagic stroke (14.6% [95% CI, 9.9%-20.0%]), acute coronary syndrome (10.8% [95% CI, 7.3%-14.8%]), renal failure (8.0% [95% CI, 2.9%-15.5%]), subarachnoid hemorrhage (6.9% [95% CI, 3.9%-10.7%]), encephalopathy (6.1% [95% CI, 1.9%-12.4%]), and the least prevalent was aortic dissection (1.8% [95% CI, 1.1%-2.8%]). Prevalence of in-hospital mortality among patients with hypertensive emergency was 9.9% (95% CI, 1.4%-24.6%). Conclusions Our findings demonstrate a pattern of hypertension-mediated organ damage primarily affecting the brain and heart, substantial cardiovascular renal morbidity and mortality, as well as subsequent hospitalization in patients with hypertensive emergencies presenting to the ED.

Impact of Diabetes and Hypertension on Left Ventricular Structure and Function: The Jackson Heart Study.

Background Diabetes and hypertension have been associated with adverse left ventricular (LV) remodeling. While they often occur concurrently, their individual effects are understudied. We aimed to assess the independent effects of diabetes and hypertension on LV remodeling in Black adults. Methods and Results The JHS (Jackson Heart Study) participants (n=4143 Black adults) with echocardiographic measures from baseline exam were stratified into 4 groups: neither diabetes nor hypertension (n=1643), only diabetes (n=152), only hypertension (n=1669), or both diabetes and hypertension (n=679). Echocardiographic measures of LV structure and function among these groups were evaluated by multivariable regression adjusting for covariates. Mean age of the participants was 52±1 years, and 63.7% were women. LV mass index was not different in participants with only diabetes compared with participants with neither diabetes nor hypertension (P=0.8). LV mass index was 7.9% (6.0 g/m2) higher in participants with only hypertension and 10.8% (8.1 g/m2) higher in participants with both diabetes and hypertension compared with those with neither (P<0.001). LV wall thickness (relative, posterior, and septal) and brain natriuretic peptide levels in participants with only diabetes were not significantly higher than participants with neither (P>0.05). However, participants with both diabetes and hypertension demonstrated higher LV wall thickness and brain natriuretic peptide levels than participants with neither (P<0.05). Conclusions In this cross-sectional analysis, diabetes was not associated with altered LV structure or function in Black adults unless participants also had hypertension. Our findings suggest hypertension is the main contributor to cardiac structural and functional changes in Black adults with diabetes.

Managing Atherosclerotic Cardiovascular Risk in Young Adults: JACC State-of-the-Art Review.

There is a need to identify high-risk features that predict early-onset atherosclerotic cardiovascular disease (ASCVD). The authors provide insights to help clinicians identify and address high-risk conditions in the 20- to 39-year age range (young adults). These include tobacco use, elevated blood pressure/hypertension, family history of premature ASCVD, primary severe hypercholesterolemia such as familial hypercholesterolemia, diabetes with diabetes-specific risk-enhancing factors, or the presence of multiple other risk-enhancing factors, including in females, a history of pre-eclampsia or menopause under age 40. The authors update current thinking on lipid risk factors such as triglycerides, non-high-density lipoprotein cholesterol, apolipoprotein B, or lipoprotein (a) that are useful in understanding an individual's long-term ASCVD risk. The authors review emerging strategies, such as coronary artery calcium and polygenic risk scores in this age group, that have potential clinical utility, but whose best use remains uncertain. Finally, the authors discuss both the obstacles and opportunities for addressing prevention in early adulthood.

Management of Stage 1 Hypertension in Adults With a Low 10-Year Risk for Cardiovascular Disease: Filling a Guidance Gap: A Scientific Statement From the American Heart Association.

High blood pressure (BP) is the leading cause of worldwide cardiovascular disease morbidity and mortality. Patients and clinicians dealing with hypertension have benefited from the evidence of event-based randomized controlled clinical trials. One result from those trials has been the development of evidence-based guidelines. The commitment to using evidence from these event-based randomized trials has been a cornerstone in the development of guideline treatment recommendations. However, in some situations, evidence from event-based trials is not available to guideline writers or clinicians for assistance in treatment decision making. Such is the case for the management of many patients with stage 1 hypertension. The purpose of this scientific statement is to provide information complementary to the 2017 Hypertension Clinical Practice Guidelines for the patient with untreated stage 1 hypertension (systolic BP/diastolic BP, 130-139/80-89 mm Hg) with a 10-year risk for atherosclerotic cardiovascular disease <10% who fails to meet the systolic BP/diastolic goal (<130/80 mm Hg) after 6 months of guideline-recommended lifestyle therapy. This statement provides evidence from sources other than event-based randomized controlled clinical trials and offers therapy options for consideration by clinicians.

Sociodemographic Determinants of Life's Simple 7: Implications for Achieving Cardiovascular Health and Health Equity Goals.

Background: Life's Simple 7 (LS7; nutrition, physical activity, cigarette use, body mass index, blood pressure, cholesterol, glucose) predicts cardiovascular health. The principal objective of our study was to define demographic and socioeconomic factors associated with LS7 to better inform programs addressing cardiovascular health and health equity. Methods: National Health and Nutrition Examination Surveys 1999-2016 data were analyzed on non-Hispanic White [NHW], NH Black [NHB], and Hispanic adults aged ≥20 years without cardiovascular disease. Each LS7 variable was assigned 0, 1, or 2 points for poor, intermediate, and ideal levels, respectively. Composite LS7 scores were grouped as poor (0-4 points), intermediate (5-9), and ideal (10-14). Results: 32,803 adults were included. Mean composite LS7 scores were below ideal across race/ethnicity groups. After adjusting for confounders, NHBs were less likely to have optimal LS7 scores than NHW (multivariable odds ratios (OR .44; 95% CI .37-.53), whereas Hispanics tended to have better scores (1.18; .96-1.44). Hispanics had more ideal LS7 scores than NHBs, although Hispanics had lower incomes and less education, which were independently associated with fewer ideal LS7 scores. Adults aged ≥45 years were less likely to have ideal LS7 scores (.11; .09-.12) than adults aged <45 years. Conclusions: NHBs were the least likely to have optimal scores, despite higher incomes and more education than Hispanics, consistent with structural racism and Hispanic paradox. Programs to optimize lifestyle should begin in childhood to mitigate precipitous age-related declines in LS7 scores, especially in at-risk groups. Promoting higher education and reducing poverty are also important.

Hypertension (Blood Pressure) and Lifetime Risk of Target Organ Damage.

PURPOSE OF REVIEW: The purpose of this review is to describe the long-term or lifetime relationship between blood pressure and target organ damage. The use of the term "blood pressure" as opposed to hypertension is purposeful. The risk of cardiovascular disease from blood pressure begins below the levels of blood pressure defined as hypertension by contemporary definitions. RECENT FINDINGS: An important recent publication that bears on this topic was the 2017 ACC/AHA Blood Pressure Management Guidelines. The redefinition of hypertension and blood pressure treatment goal to 130/80 mmHg and the decision to rely almost exclusively on data from event-based randomized controlled clinical trials, which led to a recommendation for lifestyle therapy only for most with stage 1 hypertension, were important. A report from the CARDIA study demonstrated significant risk for cardiovascular disease at 20 years for stage 1 hypertension. Based on all evidence, clinicians should consider the use of medication for stage 1 hypertension in those uncontrolled on lifestyle therapy.

Recruitment, Retention, and Engagement Strategies for Exercise Interventions With Rural Antenatal Adolescents: Qualitative Interviews With WIC Providers.

Public health stakeholder engagement is integral to developing effective public health interventions. The perspectives of women enrolled in the Special Supplemental Nutritional Program for Women, Infants, and Children (WIC) have often been sought when designing WIC-based interventions; however, the perspectives of WIC providers are underrepresented. The goal of this investigation was to explore the experiences of WIC providers who counsel adolescent clients and to identify strategies for recruitment, retention, and engagement of adolescents in an antenatal exercise intervention. Qualitative interviews were conducted with WIC providers (N = 9) in the Mississippi Delta, a rural, predominantly African American region in northwest Mississippi. From our data emerged 4 themes and 4 hypothesized strategies for recruitment, retention, and engagement of adolescent WIC clients and their parents in a future antenatal exercise intervention that will be implemented through WIC. Engaging the perspectives of WIC providers was a critical first step in understanding the context for this intervention.

Salt, No Salt, or Less Salt for Patients With Heart Failure?

Restricting dietary sodium is a common recommendation given by clinicians to patients with heart failure and is one supported by current guidelines. However, the quality of evidence for this recommendation is suboptimal, and there is no consensus on the optimal level of sodium intake. Though excessive sodium intake is associated with left ventricular hypertrophy and hypertension, recent data have suggested that very low sodium intake is paradoxically associated with worse outcomes for patients with heart failure. This is possibly explained by the association between low sodium intake and activation of the sympathetic and renin-angiotensin-aldosterone systems. Nevertheless, sodium restriction is routinely recommended and remains a cornerstone of heart failure and blood pressure therapy. In this review we discuss the pros and cons of sodium restriction for patients with heart failure from the current literature.

Population-Attributable Risk for Cardiovascular Disease Associated With Hypertension in Black Adults.

Importance: The prevalence of hypertension and the risk for hypertension-related cardiovascular disease (CVD) are high among black adults. The population-attributable risk (PAR) accounts for both prevalence and excess risk of disease associated with a risk factor. Objective: To examine the PAR for CVD associated with hypertension among black adults. Design, Setting, and Participants: This prospective cohort study used data on 12 497 black participants older than 21 years without CVD at baseline who were enrolled in the Jackson Heart Study (JHS) from September 26, 2000, through March 31, 2004, and cardiovascular events were adjudicated through December 31, 2015. The Reasons for Geographic and Racial Differences in Stroke (REGARDS) study participants were enrolled from July 1, 2003, through September 12, 2007, and cardiovascular events were adjudicated through March 31, 2016. Data analysis was performed from March 26, 2018, through July 10, 2019. Exposures: Normal blood pressure and hypertension were defined using the 2017 American College of Cardiology/American Heart Association blood pressure guideline thresholds. Main Outcomes and Measures: The PAR for CVD associated with hypertension, calculated using multivariable-adjusted hazard ratios (HRs) for CVD, coronary heart disease, heart failure, and stroke associated with hypertension vs normal blood pressure. Prevalence of hypertension among non-Hispanic black US adults 21 years and older without CVD was calculated using data from the National Health and Nutrition Examination Survey, 2011-2014. Results: Of 12 497 participants, 1935 had normal blood pressure (638 [33.0%] male; mean [SD] age, 53.5 [12.4] years), 929 had elevated blood pressure (382 [41.1%] male; mean [SD] age, 58.6 [11.8] years), and 9633 had hypertension (3492 [36.3%] male; mean [SD] age, 62.0 [10.3] years). For a maximum 14.3 years of follow-up, 1235 JHS and REGARDS study participants (9.9%) experienced a CVD event. The multivariable-adjusted HR associated with hypertension was 1.91 (95% CI, 1.48-2.46) for CVD, 2.41 (95% CI, 1.59-3.66) for coronary heart disease, 1.52 (95% CI, 1.01-2.30) for heart failure, and 2.20 (95% CI, 1.44-3.36) for stroke. The prevalence of hypertension was 53.2% among non-Hispanic black individuals. The PAR associated with hypertension was 32.5% (95% CI, 20.5%-43.6%) for CVD, 42.7% (95% CI, 24.0%-58.4%) for coronary heart disease, 21.6% (95% CI, 0.6%-40.8%) for heart failure, and 38.9% (95% CI, 19.4%-55.6%) for stroke. The PAR was higher among those younger than 60 years (54.6% [95% CI, 37.2%-68.7%]) compared with those 60 years or older (32.0% [95% CI, 11.9%-48.1%]). No differences were present in subgroup analyses. Conclusions and Relevance: These findings suggest that a substantial proportion of CVD cases among black individuals are associated with hypertension. Interventions to maintain normal blood pressure throughout the life course may reduce the incidence of CVD in this population.
