Homoarginine-A prognostic indicator in adolescents and adults with complex congenital heart disease?

ABSTRACT: Homoarginine (hArg) has been shown to be of prognostic value in patients with chronic left heart failure. The present study aims to assess the clinical utility and prognostic value of hArg levels in patients with complex congenital heart disease (CHD).Plasma hArg levels were measured in 143 patients with complex CHD and compared to clinical status, echocardiographic and laboratory parameters as well as the occurrence of adverse cardiac events.Median hArg levels were 1.5 ?mol/l in CHD patients as compared to 1.70 ?mol/l in healthy controls (p = 0.051). Median hArg levels were lowest in patients with Fontan palliation (1.27 ?mol/l) and Eisenmenger physiology (0.99 ?mol/l) and decreased with the severity of adverse cardiac events with lowest values found in patients prior to death or overt heart failure (0.89 ?mol/l). According to ROC analysis, the most important predictors of adverse cardiac events were hArg levels (AUC 0.837, p<0.001, CI 0.726-0.947), NYHA class (AUC 0.800, p<0.001, CI 0.672-0.928) and NT-proBNP levels (AUC 0.780, p<0.001, CI 0.669-0.891). The occurrence of overt heart failure or death due to progressive heart failure were best predicted by NYHA class (AUC 0.945, p<0.001, CI 0.898-0.992), hArg levels (AUC 0.911, p<0.001, CI 0.850-0.971) and NT-proBNP levels (AUC 0.877, p<0.001, CI 0.791-0.962), respectively.In patients with complex CHD, hArg levels can predict adverse cardiac events as reliably as or even better than NT-proBNP levels and thus might be of prognostic value in this subset of patients.

Project description:BackgroundThe prognostic role of the congenital heart disease (CHD) anatomic/physiologic classification has not been systematically studied. The purpose of this study was to determine whether CHD physiologic stage provided improvement in prognostic power (to predict all-cause mortality) beyond conventional clinical risk models.MethodsRetrospective study of adults with CHD at the Mayo Clinic (2003-2019). The CHD physiologic stage was assessed at baseline and 36 (24-48) months, and patients were classified into stages A to D at these time points. Clinical stability (remaining in the same stage), clinical improvement (moving to less advanced stage), and clinical deterioration (moving to more advanced stage) were determined at 36 months. We defined conventional clinical risk indices as age/sex, functional class, comorbidities, cardiac procedures, hepatorenal dysfunction, and ventricular/valvular dysfunction.ResultsOf 5321 patients, 1649 (31%), 1968 (37%), 1224 (23%), and 480 (9%) were in stages A, B, C, and D at baseline. Of 5321 patients, 4588 (86%) also had assessments at 36 months, and of these patients, 3347 (73%), 386 (8%), and 855 (19%) had clinical stability, deterioration, and improvement, respectively. Patients with clinical improvement were more likely to have undergone cardiac procedures between both assessments. Both baseline CHD physiologic stage (hazard ratio, 1.13 [95% CI, 1.09-1.17]; P<0.001, per unit increase in stage) and change in CHD physiologic stage (hazard ratio, 1.46 [95% CI, 1.32-1.61]; P=0.007, per unit increase in stage) were associated with mortality after adjustments for conventional risk indices and provided incremental improvement in prognostic power beyond conventional clinical risk models as evidence by an increase in C statistic from 0.702 (0.681-0.724) to 0.769 (0.754-0.787).ConclusionsThe CHD physiologic stage can potentially be used for risk stratification, as well as to monitor disease progression and response to therapy.

Project description:Our purpose was to study psychosocial adjustment and psychiatric morbidity of adolescents and young adults with congenital heart disease (CHD).All assessment measures were obtained on a single occasion. Clinical data was obtained through the patient's clinical records.A teaching and tertiary care facility in Porto, Portugal.We evaluated 110 CHD patients (62 male) aged from 12 to 26 years (mean=18.00±3.617), 58 cyanotic. All assessment measures were obtained on a single occasion in a tertiary hospital. Demographic information and clinical history were collected.Questionnaires regarded topics such as social support, family educational style, self-image and physical limitations, a standardised psychiatric interview Schedule for Affective Disorders and Schizophrenia-Lifetime version (SADS-L), and a self-report questionnaire on psychosocial adjustment, youth self-report or adult self-report. One of the relatives completed an observational version of the same questionnaire (child behaviour checklist (CBCL) or ABCL (adult behaviour checklist)).We found a 21.8% lifetime prevalence of psychopathology, 31.3%, in females, 14.5% in males, showing a somewhat increased proneness in CHD patients. Females also showed worse psychosocial adjustment, with more somatic complaints (u=260 000; p=0.011), anxiety/depression (u=984 000; p=0.002), aggressive behaviour (u=920 500; p=0.001), attention problems (u=1123 500; p=0.027), thought problems (u=1069 500; p=0.010), internalisation (u=869 000; p=0.0) and externalisation (u=1163 000; p=0.05). Patients with severe CHD (u=939 000; p=0.03) and surgical repair (u=719 000; p=0.037) showed worse psychosocial adjustment. Those with poor social support showed more withdrawal (u=557 500; p=0.0) and social problems (u=748 500; p=0.023), and patients with unsatisfactory school performance revealed more anxiety/depression (u=916 000; p=0.02) and attention problems (u=861 500; p=0.007).CHD males with good social support and good academic performance have a better psychosocial adjustment.

Project description:IntroductionAnxiety and depression can worsen outcome in patients with heart disease. We elucidate the prevalence of anxiety and depression in a cohort of adults with congenital heart disease (ACHD).Materials and methodsProspective screening for anxiety or depression was performed in 204 consecutive patients of the outpatient clinic of our tertiary care center using the Hospital Anxiety and Depression Scale (HADS) questionnaire and the distress thermometer (DT) as a potential ultra-short screening test. Functional data were assessed at liberty of the responsible physician. HADS scores ≥ 8 were considered doubtful and scores ≥ 11 as confirmed cases of anxiety or depression, respectively. HADS results were compared with a historical group of 100 patients with non-Hodgkin Lymphoma (NHL) as well as German reference values from the literature.ResultsPatients from the ACHD cohort were 28 ± 10 years old (mean ± SD, 54% male), 34% had a simple, 51% a moderate, including 52 patients with transposition of the great arteries after arterial switch operation, and 15% a heart defect of severe complexity. Prevalence of depression in ACHD was comparable to the German normal population (5.9% ACHD vs. 5.4% control). In contrast, prevalence of anxiety was higher than expected from reference values (12.7% ACHD vs. 5.6% control). There was a positive association between psychological distress and NYHA class [anxiety: OR 2.67 (95% CI, 1.50-4.76) p = 0.001; depression: OR 2.93 (95% CI, 1.60-5.35) p = 0.0005], but not with age, gender, or heart defect severity. Percentages of patients with ACHD with anxiety were significantly higher than in a cohort of patients with indolent non-Hodgkin lymphoma (NHL) but comparable to those with aggressive NHL (HADS-A ≥ 11: ACHD 12.7%, indolent NHL 2.2%, aggressive NHL 13.2%; p = 0.037 ACHD vs. indolent NHL; p = 0.929 ACHD vs. aggressive NHL). The distress thermometer screening test had only a fair discriminatory ability (AUC 0.708; p = 0.002) and is therefore of limited usability.ConclusionAdults with congenital heart disease exhibit an increased risk for anxiety disorders independently of the severity of the underlying heart defect. Anxiety prevalence was comparable to a historical cohort of patients with aggressive NHL underlining the importance of a routine screening for psychosocial distress in adults with congenital heart disease.
