ABSTRACT

Background Coronary artery calcium (CAC) has prognostic value for major adverse cardiovascular events (MACE) in asymptomatic individuals, whereas its role in symptomatic patients is less clear. Purpose To assess the prognostic value of CAC scoring for MACE in participants with stable chest pain initially referred for invasive coronary angiography (ICA). Materials and Methods This prespecified subgroup analysis from the Diagnostic Imaging Strategies for Patients With Stable Chest Pain and Intermediate Risk of Coronary Artery Disease (DISCHARGE) trial, conducted between October 2015 and April 2019 across 26 centers in 16 countries, focused on adult patients with stable chest pain referred for ICA. Participants were randomly assigned to undergo either ICA or coronary CT. CAC scores from noncontrast CT scans were categorized into low, intermediate, and high groups based on scores of 0, 1-399, and 400 or higher, respectively. The end point of the study was the occurrence of MACE (myocardial infarction, stroke, and cardiovascular death) over a median 3.5-year follow-up, analyzed using Cox proportional hazard regression tests. Results The study involved 1749 participants (mean age, 60 years ± 10 [SD]; 992 female). The prevalence of obstructive coronary artery disease (CAD) at CT angiography rose from 4.1% (95% CI: 2.8, 5.8) in the CAC score 0 group to 76.1% (95% CI: 70.3, 81.2) in the CAC score 400 or higher group. Revascularization rates increased from 1.7% to 46.2% across the same groups (P < .001). The CAC score 0 group had a lower MACE risk (0.5%; HR, 0.08 [95% CI: 0.02, 0.30]; P < .001), as did the 1-399 CAC score group (1.9%; HR, 0.27 [95% CI: 0.13, 0.59]; P = .001), compared with the 400 or higher CAC score group (6.8%). No significant difference in MACE between sexes was observed (P = .68). Conclusion In participants with stable chest pain initially referred for ICA, a CAC score of 0 showed very low risk of MACE, and higher CAC scores showed increasing risk of obstructive CAD, revascularization, and MACE at follow-up.

ABSTRACT

In-hospital rehabilitation can improve recovery of patients after surgery, but also contributes to the high costs of the German health system. A telemedicine-based rehabilitation used in the home as an alternative to in-hospital rehabilitation was evaluated in a pilot study. In an open trial, 170 patients performed a 3-month ambulatory rehabilitation after cardiac surgery. There were two groups (group 1 [n = 70] and group 2 [n = 100]). Group 1 participated in conventional in-hospital rehabilitation. Group 2 received ambulant rehabilitation using telemedicine. Physical performance, quality of life, (measured with a questionnaire), complications and costs were assessed and compared between the two groups. Maximal physical performance (MPP) was assessed at 6 and at 12 months after cardiac surgery. It was significantly increased by 46-54 watts in both study groups compared to their baseline value. Moreover, physical and psychological quality of life had increased in both study groups compared to baseline values. However, group 2 was the only group to show statistical significance in all categories. Fewer incidents of angina pectoris were reported within the study interval in group 2 compared to group 1 (p < 0.01). The total cost of rehabilitation was 58% lower in group 2 compared to group 1. Ambulatory rehabilitation using telemedicine improves physical performance, quality of life, is safe, and is inexpensive. Our data indicate that home-based rehabilitation is more effective than in-hospital rehabilitation for patients after cardiac surgery.

ABSTRACT

BACKGROUND AND PURPOSE: In-hospital rehabilitation can improve recovery of patients after surgery, but also contributes to the high costs of the German health system. Therefore, the possibility of a telemedically monitored rehabilitation at home as an alternative to an in-hospital rehabilitation was evaluated in a pilot study. PATIENTS AND METHODS: In an open trial, 100 patients performed an ambulatory rehabilitation after heart surgery under coverage of telemedical monitoring for 3 months. 70 patients performed a regular conventional in-hospital rehabilitation for 3 weeks. Physical performance, quality of life (questionnaire), complications, and costs were assessed and compared between the two groups. RESULTS: 6 and also 12 months after surgery, maximal physical performance was significantly increased by 46-54 W in both study groups compared to their baseline value. Moreover, physical and psychological quality of life had increased in both study groups compared to baseline values. However, only in the ambulatory group all items had increased with statistical significance. Fewer insults of angina pectoris were reported during follow-up in the ambulatory group compared to the in-hospital group (p < 0.01). Total costs of the rehabilitation were 59% lower in the ambulatory group compared to the in-hospital group. CONCLUSION: An ambulatory rehabilitation improves physical performance, quality of life, and is safe and cheap. The data of this study indicate that rehabilitation at home can be established instead of an in-hospital rehabilitation for patients after heart surgery.
