Heart disease remains one of the greatest killers. In addition to genetics and traditional lifestyle risk factors, we now understand that adverse conditions during pregnancy can also increase susceptibility to cardiovascular disease in the offspring. Therefore, the mechanisms by which this occurs and possible preventative therapies are of significant contemporary interest to the cardiovascular community. A common suboptimal pregnancy condition is a sustained reduction in fetal oxygenation. Chronic fetal hypoxia results from any pregnancy with increased placental vascular resistance, such as in preeclampsia, placental infection, or maternal obesity. Chronic fetal hypoxia may also arise during pregnancy at high altitude or because of maternal respiratory disease. This article reviews the short- and long-term effects of hypoxia on the fetal cardiovascular system, and the importance of chronic fetal hypoxia in triggering a developmental origin of future heart disease in the adult progeny. The work summarizes evidence derived from human studies as well as from rodent, avian, and ovine models. There is a focus on the discovery of the molecular link between prenatal hypoxia, oxidative stress, and increased cardiovascular risk in adult offspring. Discussion of mitochondria-targeted antioxidant therapy offers potential targets for clinical intervention in human pregnancy complicated by chronic fetal hypoxia.

Hutchinson-Gilford progeria syndrome (HGPS) is a rare disorder characterized by premature aging and death mainly because of myocardial infarction, stroke, or heart failure. The disease is provoked by progerin, a variant of lamin A expressed in most differentiated cells. Patients look healthy at birth, and symptoms typically emerge in the first or second year of life. Assessing the reversibility of progerin-induced damage and the relative contribution of specific cell types is critical to determining the potential benefits of late treatment and to developing new therapies.

Vascular homeostasis is maintained by the differentiated phenotype of vascular smooth muscle cells (VSMCs). The landscape of protein coding genes comprising the transcriptome of differentiated VSMCs has been intensively investigated but many gaps remain including the emerging roles of noncoding genes.

Brugada syndrome (BrS) is considered a purely electrical disease with variable electrical substrates. Variable rates of mechanical abnormalities have been also reported. Whether exists a link between electrical and mechanical abnormalities has never been previously explored. This investigational physiopathological study aimed to determine the relationship between the substrate size/location, as exposed by ajmaline provocation, and the severity of mechanical abnormalities, as assessed by cardiac magnetic resonance in patients with BrS.

Engagement in healthy lifestyle behaviors is suboptimal. The vast majority of the US population does not meet current recommendations. A healthy lifestyle is defined by consuming a healthy dietary pattern, engaging in regular physical activity, avoiding exposure to tobacco products, habitually attaining adequate amounts of sleep, and managing stress levels. For all these health behaviors there are well-established guidelines; however, promotion in clinical settings can be challenging. It is critical to overcome these challenges because greater promotion of heathy lifestyle practices in clinical settings effectively motivates and initiates patient behavior change. The 5A Model (assess, advise, agree, assist, and arrange) was developed to provide a framework for clinical counseling with requisite attention to the demands of clinical settings. In this science advisory, we present strategies, based on the 5A Model, that clinicians and other health care professionals can use for efficient lifestyle-related behavior change counseling in patients at all levels of cardiovascular disease risk at every visit. In addition, we discuss the underlying role of psychological health and well-being in lifestyle-related behavior change counseling, and how clinicians can leverage health technologies when providing brief patient-centered counseling. Greater attention to healthy lifestyle behaviors during routine clinician visits will contribute to promoting cardiovascular health.

We sought to investigate temporal trends in patient characteristics, waitlist, and posttransplant outcomes after heart transplantation in the United States.

Animal models implicate FGF-23 (fibroblast growth factor-23) as a direct contributor to adverse cardiorenal interactions such as sodium avidity, diuretic resistance, and neurohormonal activation, but this has not been conclusively demonstrated in humans. Therefore, we aimed to evaluate whether FGF-23 is associated with parameters of cardiorenal dysfunction in humans with heart failure, independent of confounding factors.

At a population level, engagement in healthy lifestyle behaviors is suboptimal in the United States. Moreover, marked disparities exist in healthy lifestyle behaviors and cardiovascular risk factors as a result of social determinants of health. In addition, there are specific challenges to engaging in healthy lifestyle behaviors related to age, developmental stage, or major life circumstances. Key components of a healthy lifestyle are consuming a healthy dietary pattern, engaging in regular physical activity, avoiding use of tobacco products, habitually attaining adequate sleep, and managing stress. For these health behaviors, there are guidelines and recommendations; however, promotion in clinical settings can be challenging, particularly in certain population groups. These challenges must be overcome to facilitate greater promotion of healthy lifestyle practices in clinical settings. The 5A Model (assess, advise, agree, assist, and arrange) was developed to provide a framework for clinical counseling with consideration for the demands of clinical settings. In this science advisory, we summarize specific considerations for lifestyle-related behavior change counseling using the 5A Model for patients across the life span. In all life stages, social determinants of health and unmet social-related health needs, as well as overweight and obesity, are associated with increased risk of cardiovascular disease, and there is the potential to modify this risk with lifestyle-related behavior changes. In addition, specific considerations for lifestyle-related behavior change counseling in life stages in which lifestyle behaviors significantly affect cardiovascular disease risk are outlined. Greater attention to healthy lifestyle behaviors during every clinician visit will contribute to improved cardiovascular health.

The prognostic implications of biomarker elevation following percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) lesions remain controversial. This study assessed the association of periprocedural myocardial injury and clinically relevant definition of periprocedural myocardial infarction with subsequent outcomes after CTO-PCI.

Bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) and laceration of the anterior mitral leaflet to prevent outflow obstruction (LAMPOON) reduce the risk of coronary and left ventricular outflow obstruction obstruction during transcatheter aortic valve replacement and transcatheter mitral valve replacement. Despite successful laceration, BASILICA or LAMPOON may fail to prevent obstruction caused by inadequate leaflet splay in patients having challenging anatomy such as very small valve-to-coronary distance, diffusely calcified, rigid leaflets, or undergoing transcatheter aortic valve replacement inside existing transcatheter aortic valve replacement. We describe a novel technique of balloon-augmented (BA) leaflet laceration to enhance leaflet splay.

Quantitative flow ratio (QFR) has been introduced as a novel angiography-based modality for fast hemodynamic assessment of coronary artery lesions and validated against fractional flow reserve. This study sought to define the prognostic role of pancoronary QFR assessment in patients with acute coronary syndrome (ACS) including postinterventional culprit and nonculprit vessels.

Progression of nontarget lesions (NTLs) after percutaneous coronary intervention (PCI) has been reported. However, it remains unknown whether progression of NTLs was causally related to stenting. This study was undertaken to test the hypothesis that stent implantation triggers acute phase response and systemic inflammation which may be associated with progression of NTLs.

Most patients with congenital heart disease survive into adulthood; however, residual abnormalities remain and management of the patients is life-long and personalized. Patients with surgical repair of transposition of the great arteries, for example, face the risk to develop neoaortic valve regurgitation. Cardiologists update the prognosis of the patient intuitively with updated information of the cardiovascular status of the patient, for instance from echocardiographic imaging.

Polypharmacy is associated with a poor prognosis in the elderly, however, information on the association of polypharmacy with cardiovascular outcomes in heart failure with preserved ejection fraction is sparse. This study sought to investigate the relationship between polypharmacy and adverse cardiovascular events in patients with heart failure with preserved ejection fraction.

Diuretics are a mainstay therapy for the symptomatic treatment of heart failure. However, in contemporary US outpatient practice, the degree to which diuretic dosing changes over time and the associations with clinical outcomes and health care resource utilization are unknown.

Hypertrophic cardiomyopathy (HCM) is a complex disease partly explained by the effects of individual gene variants on sarcomeric protein biomechanics. At the cellular level, HCM mutations most commonly enhance force production, leading to higher energy demands. Despite significant advances in elucidating sarcomeric structure-function relationships, there is still much to be learned about the mechanisms that link altered cardiac energetics to HCM phenotypes. In this work, we test the hypothesis that changes in cardiac energetics represent a common pathophysiologic pathway in HCM.
