Doppler-derived pulmonary pulse transit time measurements in chronic obstructive pulmonary disease: Reproducibility and cardiopulmonary function.

INTRODUCTION: Doppler-derived pulmonary pulse transit time (pPTT) is an auspicious hemodynamic marker in chronic pulmonary diseases. The aim is to compare four distinct pPTT measurements and its relation to right cardiac and pulmonary function. METHODS: Prospectively, 25 chronic obstructive pulmonary disease (COPD) patients (four patients excluded) and 32 healthy subjects underwent repeated distinct pPTT measurements, standard echocardiography, and pulmonary function testing on the same day. pPTT was defined as the interval from the R or Q-wave in the electrocardiogram to the corresponding pulse wave Doppler peak late systolic (S) 2 or diastolic (D) pulmonary vein flow velocity (pPTT R-S, Q-S, R-D, Q-D). Reproducibility was assessed using Bland-Altman analysis, coefficient of variation (COV), intraclass correlation coefficient (ICC), and power calculations. Associations with right ventricular RV tissue and pulse wave Doppler velocities (RV E', RV S', RV A', RV E, RV A, RV E/E', RV E/A), TAPSE, right ventricular fractional area change, left ventricular systolic and diastolic function (LV ejection fraction, E, A, E/A, E/E', septal E', lateral E'), LA diameters, as well as forced expiratory volume in 1 s, forced vital capacity (FVC) predicted (%), and in liters were analyzed. RESULTS: There was no significant difference and no bias between pPTT measures (p range: .1-.9). COV was in COPD 1.2%-2.3%, in healthy subjects 1.0%-3.1%. ICC ranged from .92 (COPD) to .96 (healthy subjects). In COPD significant correlations were found for pPTT R-S, Q-S and R-D with RV E`, (all > ρ: .49, < p = .0364), pPTT R-S, Q-S with RV E/E` (both > ρ: .49, < p = .0291), pPTT Q-S with RV S´ (ρ: .58, p = .0134), RV A (ρ: .59, p = .0339) and heart rate > ρ: -.39, < p = .0297). pPTT R-S, R-D showed significant correlations with FVC predicted (%) (ρ: .48 p = .0224) and FVC (l) (ρ:.47 p = .0347). CONCLUSIONS: All pPTT measures exhibited high reproducibility. In COPD patients pPTT measures correlate with diastolic right ventricular function. Defining Q as starting point seems clinically advantageous considering electromechanical desynchrony in patients with conduction disorders.

Impact of congenital heart disease on personality disorders in adulthood.

BACKGROUND AND AIMS: Adults with congenital heart disease (ACHD) constitute an ever-growing patient population characterized by high risks for cardiovascular- and mental disorders. Personality disorders (PDs) are associated with adverse physical and mental health. Studies assessing PD prevalence in ACHD are lacking. METHODS: PD point prevalence was assessed in 210 ACHD by Structured Clinical Interview for Axis-II Personality Disorders (SCID-II) and compared to meta-analytical data from the general population. Depression and anxiety were measured by self-report (Hospital Anxiety and Depression Scale, HADS) and clinician-rating (Montgomery-Åsberg depression rating scale, MADRS). Childhood maltreatment was assessed with the Childhood Trauma Questionnaire and quality-of-life (QOL) with the World Health Organization QOL Scale. RESULTS: PD prevalence was markedly higher in ACHD compared to general population (28.1% vs. 7.7%). Particularly borderline (4.8% vs. 0.9%) and cluster C (i.e. anxious or fearful; 17.1% vs. 3.0%) PDs were overrepresented. PD diagnosis was associated with a surgery age ≤12 years (χ²(1)=7.861, φ=.195, p=.005) and higher childhood trauma levels (U=2583.5, Z=-3.585, p<.001). ACHD with PD reported higher anxiety (HADS-A: U=2116.0, Z=-5.723, p<.001) and depression (HADS-D: U=2254.5, Z=-5.392, p<.001; MADRS: U=2645.0, Z=-4.554, p<.001) levels and lower QOL (U=2538.5, Z=-4.723, p<.001). CONCLUSIONS: PDs, particularly borderline- and cluster C, are significantly more frequent in ACHD compared to general population and associated with depression, anxiety and decreased QOL. Data from the general population suggest an association with adverse cardiometabolic and mental health. To ensure guideline-based treatment, clinicians should be aware of the increased PD risk in ACHD.

Adults with congenital heart disease (ACHD) constitute an ever-growing patient population characterized by an increased cardiovascular disease risk. Personality disorders (PDs) are associated with adverse mental and physical, in particular cardiovascular, health in the general population. Studies assessing PD prevalence in ACHD have been lacking to date. PDs, particularly borderline PD and cluster C (anxious or fearful) PDs, are highly prevalent in ACHD. PDs are associated with heightened levels of anxiety and depression and decreased quality of life in ACHD. Heart surgery before puberty and increased levels of childhood maltreatment are associated with PD diagnosis.

Impact of COVID-19 on Medical Supply in Adults With Congenital Heart Disease.

Introduction: In March 2020, the World Health organization declared COVID-19 a global pandemic. One year later, the direct and indirect burden of the COVID-19 pandemic become more visible. In this context, there is concern about the allocation of medical resources and medical treatment of other diseases than COVID-19. Particularly, patients with chronic diseases need constant medical and pharmacological treatment. Therefore, we evaluated a large cohort of patients with adult congenital heart disease (ACHD) regarding postponed medical appointments and their possibilities to receive medical treatment during the COVID-19 pandemic. Methods: This cross-sectional study included 559 patients with ACHD (mean age 37.32 ± 11.98; 47% female). Clinical characteristics, answers to questionnaires concerning lifestyle, psychological well-being, addictive behavior and adherence were related to postponed medical appointments and limited access to medical care. Results: One hundred and nine patients (19.5%) reported problems getting necessary medical treatment or visiting a physician. Higher anxiety levels (p = 0.004) emerged as the main factor associated with medical undertreatment. The main risk factors for postponement of least one medical appointment (n = 91) were higher depression (p = 0.013) and anxiety (p = 0.05) symptoms as well as female sex (p ≤ 0.0001) and documented arrhythmias (p = 0.007) indicating a particular risk group of cardiovascular complications. In contrast, frequent physical activity identified patients at lower risk. Conclusion: In ACHD anxiety and depressive symptoms handicap patients to receive medical care. Postponement of medical appointments additionally relates to female sex and documented arrhythmias. The latter indicates that patients at high risk of adverse cardiac outcome avoid routine medical care. Our data may lead policy makers to develop strategies for the provision of medical services to particular vulnerable patient groups, and to optimize management of both future pandemics and daily routine.

Validation of Phase-Resolved Functional Lung (PREFUL) Magnetic Resonance Imaging Pulse Wave Transit Time Compared to Echocardiography in Chronic Obstructive Pulmonary Disease.

BACKGROUND: Phase-resolved functional lung (PREFUL) magnetic resonance imaging (MRI) pulmonary pulse wave transit time (pPTT) is a contrast agent free, vascular imaging biomarker, but has not been validated in chronic obstructive pulmonary disease (COPD). PURPOSE: To validate PREFUL with echocardiographic pPTT as a reference standard and to compare arterial/venous pPTT mapping with spirometry and clinical parameters. STUDY TYPE: Prospective. POPULATION: Twenty-one patients (62% female) with COPD and 44 healthy participants (50% female). FIELD STRENGTH/SEQUENCE: 1.5 T; 2D-spoiled gradient-echo sequence. ASSESSMENT: Three coronal PREFUL MRI slices, echocardiography, and spirometry including forced expiratory volume in 1 second (FEV1, liter) and predicted defined as FEV1 in% divided by the population average FEV1%, were performed. Pulmonary pulse transit time from the main artery to the microvasculature (PREFUL pPTT), to the right upper lobe vein (PREFUL pPTTav , echo pPTTav ), from microvasculature to right upper lobe vein (PREFULvein ) and the ratio of PREFUL pPTT to PREFUL pPTTvein were calculated. Body mass index (BMI), Global Initiative for COPD (GOLD) stage 1-4, disease duration, and cigarette packs smoked per day multiplied by the smoked years (pack years) were computed. STATISTICAL TESTS: Shapiro-Wilk-test, paired-two-sided-t-tests, Bland-Altman-analysis, coefficient of variation, Pearson ρ were applied, pPTT data were compared between 21 subjects from the 44 healthy subjects who were age- and sex-matched to the COPD cohort, P < 0.05 was considered statistically significant. RESULTS: PREFUL pPTTav significantly correlated with echo pPTTav (ρ = 0.95) with 1.85 msec bias, 95% limits of agreement: 55.94 msec, -52.23 msec in all participants (P = 0.59). In the healthy participants, PREFUL and echo pPTTav significantly correlated with age (ρ = 0.81, ρ = 0.78), FEV1 (ρ = -0.47, ρ = -0.34) and BMI (ρ = 0.56, ρ = 0.51). In COPD patients, PREFUL pPTT significantly correlated with FEV1 predicted (ρ = -0.59), GOLD (ρ = 0.53), disease duration (ρ = 0.54), and pack years (ρ = 0.49). DATA CONCLUSION: Arteriovenous PTT measured by PREFUL MRI corresponds precisely to echocardiography and appears to be feasible even in severe COPD. EVIDENCE LEVEL: 1 TECHNICAL EFFICACY: Stage 2.

Factors That Influence Adherence to Medication in Adults With Congenital Heart Disease (ACHD).

Objective: Innovative operative and interventional procedures have improved survival in congenital heart disease (CHD), and today more than 90% of these children reach adulthood. Consequently, adherence and psychosocial issues are becoming increasingly important because non-adherence to treatment recommendations worsens morbidity and mortality. This study aimed to identify factors modifying adherence to medication in adult congenital heart disease (ACHD). Methods: This cross-sectional study included 451 outpatients (female 47.9%, average age ± SD: 37.9 ± 12 years) from the ACHD department, who completed a questionnaire assessing medication non-adherence and individual barriers to treatment. Further assessments included psychological well-being (Hospital Anxiety and Depression scale; HADS), childhood traumatization, sociodemographic, and clinical data. Binary logistic regression analysis calculated the impact of these factors on drug adherence. Results: Of the 451 patients 162 participants (35.9%) reported to be non-adherent. In univariate analysis non-adherence to treatment was associated with smoking (P = < 0.001) and internet addiction (P = 0.005). Further factors negatively influencing adherence were the presence of depressive symptoms (P = 0.002), anxiety (P = 0.004), and childhood traumatization (p = 0.002). Factors positively associated with adherence were older age (P = 0.003) and more advanced heart disease as indicated by NYHA class (P = 0.01), elevated NT-proBNP (P = 0.02), device therapy (P = 0.002) and intermittent arrhythmias (P = 0.01). In multivariate analysis especially psychopathological factors such as depression (P = 0.009), anxiety (P = 0.032) and childhood traumatization (P = 0.006) predicted non-adherence. Conclusion: Adherence is a critical issue in the long-term management of ACHD. Identifying modifiable factors that worsen adherence offers the opportunity for targeted interventions. Depressive symptoms, anxiety, and adverse childhood experiences are amenable to psychosocial interventions, as well as cigarette smoking. Our study suggests that a multimodal and interdisciplinary treatment concept for the long-term management of adults with congenital heart disease could be beneficial. Whether it will further improve morbidity and mortality, should be assessed in prospective interventions.
