Review of Digitalized Patient Education in Cardiology: A Future Ahead?

INTRODUCTION: An increased focus on shared decision-making and patient empowerment in cardiology and on patient outcomes such as quality of life (QoL), depression, and anxiety underline the importance of high-quality patient education. Studies focusing on digital means of patient education performed in other disciplines of medicine demonstrated its positive effect in these areas. Therefore, a review of the current literature was performed to (i) evaluate the status of innovative, digitalized means of patient education in cardiology and (ii) assess the impact of digital patient education on outcome parameters (i.e., patient knowledge (or health literacy), QoL, depression, anxiety, and patient satisfaction). METHOD: A review of the current literature was performed to evaluate the effect of digitalized patient education for any purpose in the field of cardiology. Medline and EMBASE were searched for articles reporting any digital educational platform used for patient education up to May 2020. The articles were compared on their effect on patient knowledge or health literacy, QoL, depression or anxiety, and patient satisfaction. RESULTS: The initial search yielded 279 articles, 34 of which were retained after applying in, and exclusion criteria. After full-text analysis, the total number of articles remaining was 16. Of these, 6 articles discussed the use of smartphone or tablet applications as a means of patient education, whereas 3 reviewed web-based content, and 7 evaluated the use of video (2 three-dimensional videos, from which one on a virtual reality headset). CONCLUSION: This review demonstrates that digital patient education increases patient knowledge. Overall, digital education increases QoL and lowers feelings of depression and anxiety. The majority of patients express satisfaction with digital platforms. It remains important that developers of digital patient education platforms remain focused on clear, structured, and comprehensible information presentation.

Diagnostic Accuracy of the Standing Test in Adults Suspected for Congenital Long-QT Syndrome.

Background An elegant bedside provocation test has been shown to aid the diagnosis of long-QT syndrome (LQTS) in a retrospective cohort by evaluation of QT intervals and T-wave morphology changes resulting from the brief tachycardia provoked by standing. We aimed to prospectively determine the potential diagnostic value of the standing test for LQTS. Methods and Results In adults suspected for LQTS who had a standing test, the QT interval was assessed manually and automated. In addition, T-wave morphology changes were determined. A total of 167 controls and 131 genetically confirmed patients with LQTS were included. A prolonged heart rate-corrected QT interval (QTc) (men ≥430 ms, women ≥450 ms) at baseline before standing yielded a sensitivity of 61% (95% CI, 47-74) in men and 54% (95% CI, 42-66) in women, with a specificity of 90% (95% CI, 80-96) and 89% (95% CI, 81-95), respectively. In both men and women, QTc≥460 ms after standing increased sensitivity (89% [95% CI, 83-94]) but decreased specificity (49% [95% CI, 41-57]). Sensitivity further increased (P<0.01) when a prolonged baseline QTc was accompanied by a QTc≥460 ms after standing in both men (93% [95% CI, 84-98]) and women (90% [95% CI, 81-96]). However, the area under the curve did not improve. T-wave abnormalities after standing did not further increase the sensitivity or the area under the curve significantly. Conclusions Despite earlier retrospective studies, a baseline ECG and the standing test in a prospective evaluation displayed a different diagnostic profile for congenital LQTS but no unequivocal synergism or advantage. This suggests that there is markedly reduced penetrance and incomplete expression in genetically confirmed LQTS with retention of repolarization reserve in response to the brief tachycardia provoked by standing.

Safety and effectiveness of home-based, self-selected exercise training in symptomatic adults with congenital heart disease: A prospective, randomised, controlled trial.

BACKGROUND: The purpose of this prospective randomised controlled trial was to assess whether home-based, self-selected exercise training is safe, results in high compliance and improves exercise capacity in symptomatic adults with congenital heart disease (CHD). METHODS: Forty adults with moderate or severe CHD (40 ±â€¯12 years, 56% male, New York Heart Association [NYHA] II/III 37/3) were randomly assigned, stratified by CHD complexity, either to home-based exercise training or usual care. The exercise training protocol consisted of three exercise sessions per week for six consecutive months. Patients were free to choose any sports of their preference. RESULTS: Thirty-four patients (each randomisation group n = 17) completed the protocol and were analysed. The majority was involved in high-dynamic sports (76%); none had to discontinue the training programme due to exercise-related adverse events. More than 70% adhered to the exercise programme at or above the target training level. Peak VO2 increased significantly in the exercise group by +1.7 ±â€¯2.7 ml∙kg∙min-1 (p = 0.025), whereas it remained unchanged in the control group by +0.8 ±â€¯2.2 ml∙kg∙min-1 (p = 0.184). No significant changes were found in serum N-Terminal pro-brain natriuretic peptide levels or quality of life in either randomisation group or between groups. CONCLUSIONS: In symptomatic adults with moderate or severe CHD, home-based exercise training of their preference appeared safe, with good compliance and favourable effects on exercise capacity. Our results demonstrate that it is appropriate to stimulate our patients to regularly perform moderate to vigorous physical activities, in absence of medical restrictions.

The effect of exercise training in symptomatic patients with grown-up congenital heart disease: a review.

INTRODUCTION: The number of grown-up congenital heart disease (GUCH) patients is steadily increasing. Unfortunately, the majority of these patients suffer from late sequelae, with heart failure being the most common cause of death. Exercise training is beneficial and safe in patients with acquired heart failure, as well as in asymptomatic GUCH patients. However, its effect remains unknown in symptomatic GUCH patients. This could cause reticence on positive sports advice, with possible counterproductive effects. Areas covered: A review of current literature was performed to evaluate the effect of exercise training in symptomatic (NYHA≥2) GUCH patients. The search yielded a mere three studies including symptomatic patients, and another six studies including also patients in NYHA 1 without making clear distinction between the NYHA subgroups. Expert commentary: Suboptimal trial designs, low patient numbers, and homogeneity of investigated cardiac anomalies make this review insufficient to draw definite conclusions. However, all studies describe overall positive effects of exercise training in symptomatic GUCH patients in terms of exercise capacity and quality of life. There were no safety concerns. Larger-scaled, randomized controlled trials are needed to obtain certainty.
