International Initiatives of the American Heart Association: Original Concepts, Present Programs, and Future Focus: A Science Advisory From the American Heart Association.

The American Heart Association (AHA), founded in 1924, is anchored in the core belief that scientific research can lead the way to better prevention, treatment, recovery, and ultimately a cure for cardiovascular disease. Historically, the association's involvement in international efforts centered on scientific cooperation. Activities mostly involved AHA leadership presenting at international scientific meetings and leaders from other countries sharing scientific and medical information at AHA meetings. Although the AHA's and American Stroke Association's international efforts have expanded substantially since those early days, global knowledge exchange remains the bedrock of its international endeavors. As the AHA turns 100, we reflect on the successful global efforts in prevention, resuscitation, global advocacy, quality improvement, and health equity that have guided the organization to a place of readiness for "advancing health and hope, for everyone, everywhere." Motivated by the enormous potential for population health gains in an aging world, the AHA is entering its second century with redoubled commitment to improving global cardiovascular and cerebrovascular health for all.

Myocardial infarction with nonobstructive coronary arteries: a single-center retrospective study by sex and race.

BACKGROUND: In myocardial infarction with nonobstructive coronary arteries (MINOCA), there are limited patient-level data on outcomes by sex and race. OBJECTIVE: The aim of this study was to assess baseline demographics and 3-year outcomes by sex and race for MINOCA patients. METHODS: Patients admitted to a single center with acute myocardial infarction (MI) between 1 January 2012 and 31 December 2018, were identified by chart and angiographic review. The primary outcome was nonfatal MI with secondary outcomes including nonfatal cerebrovascular accident (CVA), chest pain readmission, and repeat coronary angiography. RESULTS: During the study period, 304 patients were admitted with MINOCA. The cohort was predominantly female (66.4%), and women were significantly older (64.6 vs. 59.2). One-sixth of the total population were Black patients, and nearly half of Black patients (47.2%) were male. Prior CVA (19.7%) and comorbid anxiety, depression, or post-traumatic stress disorder (41.1%) were common. Rates of nonfatal MI were 6.3% without difference by sex or race. For secondary outcomes, rates of CVA were 1.7%, chest pain readmission was 22.4%, and repeat angiography was 8.9%. Men were significantly more likely to have repeat angiography (13.7 vs. 6.4%), and Black patients were more likely to be readmitted for angina (34.0 vs. 19.1%). Over one-quarter of patients underwent repeat stress testing, with 8.9% ultimately undergoing repeat angiograms and low numbers (0.7%) undergoing revascularization. Men were more likely to be referred for a repeat angiogram (13.7 vs. 6.4%, P = 0.035). In multivariate analysis, Black race [odds ratio (OR), 2.31; 95% confidence interval (CI), 1.06-5.03] was associated with an increased risk of readmission for angina, while female sex was associated with decreased odds of repeat angiography (OR, 0.36; 95% CI, 0.14-0.90) and current smoking was associated with increased odds of repeat angiography (OR, 4.07; 95% CI, 1.02-16.29)] along with hyperlipidemia (OR, 4.65; 95% CI, 1.22-17.7). CONCLUSION: White women presented more frequently with MINOCA than White men, however, Black men are equally as affected as Black women. Rates of nonfatal MI were low without statistical differences by sex or race.

TAVR in Older Adults: Moving Toward a Comprehensive Geriatric Assessment and Away From Chronological Age: JACC Family Series.

Calcific aortic stenosis can be considered a model for geriatric cardiovascular conditions due to a confluence of factors. The remarkable technological development of transcatheter aortic valve replacement was studied initially on older adult populations with prohibitive or high-risk for surgical valve replacement. Through these trials, the cardiovascular community has recognized that stratification of these chronologically older adults can be improved incrementally by invoking the concept of frailty and other geriatric risks. Given the complexity of the aging process, stratification by chronological age should only be the initial step but is no longer sufficient to optimally quantify cardiovascular and noncardiovascular risk. In this review, we employ a geriatric cardiology lens to focus on the diagnosis and the comprehensive management of aortic stenosis in older adults to enhance shared decision-making with patients and their families and optimize patient-centered outcomes. Finally, we highlight knowledge gaps that are critical for future areas of study.

Cardiovascular Disease in the Older Adult: Where Are We 4 Decades Later?

The 1986 Bethesda Conference on Cardiovascular Disease (CVD) in the Elderly, co-chaired by Drs. Nanette Wenger, Frank Marcus, and Robert O'Rourke, delineated the anticipated social, political, ethical, economic and technological impact of an aging population on the incidence, prevalence, and management of CVD in the US and worldwide. In the ensuing 4 decades, older patients have come to comprise an increasingly large proportion of the CVD population, and there has been an explosion of research in all aspects of CVD affecting older adults. Correspondingly, Geriatric Cardiology is now an established field within cardiovascular medicine. In this communication, we provide a focused update on intersections between CVD and geriatrics from basic science to clinical practice, a review of major advances in diagnosis and treatment of older adults with CVD, and a preview of future research directions in the still evolving field of geriatric cardiology.

Valve-in-Valve Transcatheter Aortic Valve Replacement During Second Trimester of Pregnancy.

Critical bioprosthetic aortic valve stenosis is a rare finding in the second trimester of pregnancy. We present the case of a successful valve-in-valve transcatheter aortic valve replacement in a 16-weeks-pregnant patient. We describe the significant role of the multidisciplinary heart team during preconception and pregnancy.

Effects of a patient-centered digital health intervention in patients referred to cardiac rehabilitation: the Smart HEART clinical trial.

BACKGROUND: Cardiac rehabilitation (CR) improves outcomes in heart disease yet remains vastly underutilized. Remote CR enhanced with a digital health intervention (DHI) may offer higher access and improved patient-centered outcomes over non-technology approaches. We sought to pragmatically determine whether offering a DHI improves CR access, cardiac risk profile, and patient-reported outcome measures. METHODS: Adults referred to CR at a tertiary VA medical center between October 2017 and December 2021 were offered enrollment into a DHI alongside other CR modalities using shared decision-making. The DHI consisted of remote CR with a structured, 3-month home exercise program enhanced with multi-component coaching, a commercial smartphone app, and wearable activity tracker. We measured completion rates among DHI participants and evaluated changes in 6-min walk distance, cardiovascular risk factors, and patient-reported outcomes from pre- to post-intervention. RESULTS: Among 1,643 patients referred to CR, 258 (16%) consented to the DHI where the mean age was 60 ± 9 years, 93% were male, and 48% were black. A majority (90%) of the DHI group completed the program. Over 3-months, significant improvements were seen in 6MWT (mean difference [MD] -29 m; 95% CI, 10 to 49; P < 0.01) and low-density lipoprotein cholesterol (MD -11 mg/dL; 95% CI, -17 to -5; P < 0.01), and the absolute proportion of patients who reported smoking decreased (10% vs 15%; MD, -5%; 95% CI, -8% to -2%; P < 0.01) among DHI participants with available data. No adverse events were reported. CONCLUSIONS: The addition of a DHI-enhanced remote CR program was delivered in 16% of referred veterans and associated with improved CR access, markers of cardiovascular risk, and healthy behaviors in this real-world study. These findings support the continued implementation of DHIs for remote CR in real-world clinical settings. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov: NCT02791685 (07/06/2016).

Redefining the Roles of Aspirin across the Spectrum of Cardiovascular Disease Prevention.

Even before its role in platelet inhibition was fully characterized in the 1980s, aspirin had been incorporated into the cardiovascular disease care algorithm. Early trials examining its use in unstable angina and acute myocardial infarction revealed evidence of its protective role in the secondary prevention of atherosclerotic cardiovascular disease (ASCVD). Large trials assessing use in the primary prevention setting and optimal dosing regimens were studied in the late 1990s and early 2000s. As a cornerstone of cardiovascular care, aspirin was incorporated into primary and secondary ASCVD prevention guidelines in the United States and mechanical heart valve guidelines. However, in recent years, with significant advances in medical and interventional ASCVD therapies, scrutiny has been placed on the bleeding profile of aspirin, and guidelines have adapted to new evidence. Updates in primary prevention guidelines reserve aspirin only for patients at higher ASCVD risk and low bleeding risk - though questions remain in ASCVD risk assessment as risk-enhancing factors have proven difficult to incorporate on a population level. New thoughts regarding aspirin use in secondary prevention - especially with the concomitant use of anticoagulants - have altered recommendations as additional data accrued. Finally, a recommendation for aspirin and vitamin K antagonists with mechanical heart valves has been modified. Despite aspirin losing a foothold in cardiovascular care, new evidence has strengthened claims for its use in women at high risk for preeclampsia.

Leadless Pacemakers: State of the Art and Selection of the Ideal Candidate.

The field of cardiac pacing has been defined by constant development to provide efficacious, safe, and reliable therapy. Traditional pacing utilizes transvenous leads, which dwell in the venous system and place patients at risk for complications, including pneumothorax, bleeding, infection, vascular obstruction, and valvular compromise. Leadless pacemakers have been developed to overcome many of the challenges of transvenous pacing while providing safe and effective pacing therapy for an increasing population of patients. The Medtronic Micra transcatheter pacing system was approved by the FDA in April of 2016 and the Abbott Aveir pacemaker was approved in April of 2022. Several additional leadless pacemakers are in various stages of development and testing. There exists limited guidance on the selection of the ideal candidate for leadless pacemakers. Advantages of leadless pacemakers include decreased infection risk, overcoming limited vascular access, and avoidance of interaction with the tricuspid valve apparatus. Disadvantages of leadless pacemakers include right ventricular-only pacing, unclear lifecycle management, cost, perforation risk, and lack of integration with defibrillator systems. This review aims to provide an overview of the current state of the art of leadless pacemakers, currently approved systems, clinical trials and real-world evidence, considerations for patient selection, and future directions of this promising technology.

Patient-centered care in geriatric cardiology.

Geriatric cardiology involves providing cardiovascular care to older adults in relation to aging. Although cardiovascular diseases are the most common diseases faced by older adults, they often co-occur with numerous aging-related challenges, such as multimorbidity, frailty, polypharmacy, falls, functional and cognitive impairment, which present challenges to implementing standard disease-based treatment strategies. Faced with these complexities, patient-centered care in geriatric cardiology strives to direct all management toward the achievement of an individual's prioritized health and life goals by employing shared decision-making to align treatment with goals, utilizing stated goals to navigate situations of treatment uncertainty, and pro-actively mitigating aging-related risks. This fundamental change in cardiovascular medicine from disease-centered management to patient-centered goal-directed care is necessary to facilitate wellness, independence, and favorable quality of life outcomes in the older adult population.

Sex-specific disparities in patients undergoing isolated CABG.

Study objective: Examine sex-specific characteristics in patients undergoing coronary artery bypass grafting (CABG) at our institution. Design: Retrospective chart review was performed utilizing our institutional Society of Thoracic Surgeons (STS) database. Setting: An academic, quaternary care center from 2010 to 2021. Participants: 3163 females and 9573 males underwent isolated CABG. Interventions: The institutional STS database was queried for preoperative, intraoperative, and postoperative variables. Main outcome measures: Univariate comparisons between female and male groups were performed using chi-squared tests or fisher exact tests. Multivariate logistic regression was used to assess risk factors for 30-day mortality. Results: Females had more preoperative comorbidities than males, including hypertension, diabetes, peripheral arterial disease, cerebrovascular disease, renal failure, and prior myocardial infarction. Females more frequently underwent urgent (61 % vs. 58 %) or emergent CABG (5.8 % vs. 4.3 %) compared to males (p < 0.0001). Females experienced longer total intensive care unit (ICU) hours (48.3 h vs. 43.5 h) (p < 0.0001), were more frequently discharged to an extended care facility (13 % vs. 6.4 %) (p < 0.0001) and prescribed less aspirin and beta blocker therapy at discharge than males. In-hospital mortality was higher in females (1.9 % vs. 1.2 %, p = 0.002), as was 30-day mortality (2.7 % vs. 1.6 %, p = 0.0001). Female sex was an independent risk factor for 30-day mortality (odds ratio = 1.46, 95 % CI: 1.06, 2.03, p = 0.02). Conclusion: Over the past decade, females undergoing CABG had more preoperative comorbidities, urgent and emergent operations, longer postoperative ICU stay and a higher risk of mortality than their male counterparts. Further studies must investigate these disparities to improve outcomes for females undergoing CABG.
