Cardiac Denial and Psychological Predictors of Cardiac Care Adherence in Adults With Congenital Heart Disease.

The current study examined cardiac denial and psychological predictors (i.e., depression, anxiety) of health outcomes including medical nonadherence and physical health in a sample of 80 adults with congenital heart disease (ACHD). Results indicated that denial of impact was elevated in this patient group compared with reference groups, and denial was negatively associated with depression and anxiety at ps < .01. Results indicated that depression, anxiety, and denial predicted unique variance in medical nonadherence, and gender moderated the relationships between these psychological factors and nonadherence. For depression, men and women showed similar relationships between depression and nonadherence at high levels of depression; however, at low levels of depression (i.e., a more normal mood state), men were less adherent compared with women. For anxiety, men and women did not differ in adherence at low levels of anxiety; however, men experiencing high anxiety were less adherent compared with women experiencing high anxiety. Implications of this study are discussed including the role of gender and denial and the impact of denial functioning to reduce negative affect. Depression was the only significant predictor of physical functioning. Results of this study suggest that psychological interventions aimed at depression and anxiety may function differently across gender to improve patient medical adherence and improve physical functioning in ACHD.

Clinical and Psychological Drivers of Perceived Health Status in Adults With Congenital Heart Disease

The factors having the greatest impact on self-reported health status in adults with congenital heart disease (ACHD) remain incompletely studied. We conducted a single-site, cross-sectional study of ACHD patients followed at the Center for ACHD at Washington University School of Medicine, including retrospectively gathered clinical data and psychometric and health status assessments completed at the time of enrollment. To identify primary drivers of perceived health status, we investigated the impact of the demographic, clinical, and psychological variables on self-reported health status as assessed using the Rand 36-Item Short Form Health Survey. Variables with significant associations within each domain were considered jointly in multivariable models constructed via stepwise selection. There was domain-specific heterogeneity in the variables having the greatest effect on self-reported health status. Depression was responsible for the greatest amount of variability in health status in all domains except physical functioning. In the physical functioning domain, depression remained responsible for 5% of total variability, the third most significant variable in the model. In every domain, depression more strongly influenced health status than did any cardiac-specific variable. In conclusion, depression was responsible for a significant amount of heterogeneity in all domains of self-perceived health status. Psychological variables were better predictors of health status than clinical variables.

Effects of eplerenone on markers of myocardial fibrosis, 6-minute walk distance, and quality of life in adults with tetralogy of Fallot and complete transposition of the great arteries

ABSTRACT Ventricular dysfunction is common among patients with repaired cyanotic congenital heart disease. To date, no pharmacologic intervention has been demonstrated to be beneficial in this setting. To begin addressing this knowledge gap, we conducted a single-center prospective, randomized, open-label pilot study to investigate the effects of eplerenone on serologic markers of collagen turnover and inflammation, 6-minute walk distance, and quality of life in patients with tetralogy of Fallot (TOF) or transposition of the great arteries with a systemic right ventricle (transposition of the great arteries [TGA]). Patients were randomized to a 3-month drug-free period at the beginning of the treatment period or at the end. All patients received 12 months of eplerenone therapy during the treatment period. Twenty-six patients were enrolled in the trial; 17 completed the study protocol: 8 with TOF and 9 with TGV. Eplerenone had no effect on serum levels of procollagen 1 N-terminal peptide (PINP), procollagen 3 N-terminal peptide (PIIINP), or galectin-3 (G3). Similarly, eplerenone had no effect on 6-minute walk distance or quality of life. In conclusion, PINP and PIIINP levels are as high as or higher in patients with TOF and TGA than in patients with normal cardiac anatomy and heart failure, whereas G3 levels are lower. Eplerenone is well tolerated by adults born with congenital heart disease.

Primary Prevention of Sudden Cardiac Death in Adults with Transposition of the Great Arteries: A Review of Implantable Cardioverter-Defibrillator Placement.

Transposition of the great arteries encompasses a set of structural congenital cardiac lesions that has in common ventriculoarterial discordance. Primarily because of advances in medical and surgical care, an increasing number of children born with this anomaly are surviving into adulthood. Depending upon the subtype of lesion or the particular corrective surgery that the patient might have undergone, this group of adult congenital heart disease patients constitutes a relatively new population with unique medical sequelae. Among the more common and difficult to manage are cardiac arrhythmias and other sequelae that can lead to sudden cardiac death. To date, the question of whether implantable cardioverter-defibrillators should be placed in this cohort as a preventive measure to abort sudden death has largely gone unanswered. Therefore, we review the available literature surrounding this issue.

RACIAL DIFFERENCES IN RATES OF AORTIC VALVE REPLACEMENT IN PATIENTS WITH SEVERE AORTIC STENOSIS

Racial disparities exist in treatment of various cardiovascular diseases. Aortic valve replacement (AVR) is the only treatment for aortic stenosis (AS) shown to improve symptoms and survival. To date, no studies have evaluated the rate of AVR among different races. We propose that African Americans
