PMID 35891912WHAT IT FOUND
After two months, patients after PCI who received a nurse-led multidisciplinary exercise package plus routine care walked farther, exercised more regularly, and reported better knowledge, confidence and support than routine care alone.
Key findings
01The 6-minute walking distance was higher in the intervention group than in the control group after the intervention (469.36 ± 57.48 m versus 432.81 ± 67.09 m; P = 0.042).
02Good exercise compliance was more common in the intervention group: 7 of 25 patients versus 2 of 26 control patients (P = 0.004).
03Disease knowledge, self-efficacy and perceived social support were higher in the intervention group after the intervention (knowledge 52.64 ± 9.82 versus 42.42 ± 8.54; self-efficacy 42.40 ± 8.04 versus 36.88 ± 7.73; social support 74.04 ± 5.73 versus 66.69 ± 6.86; all P < 0.05).

What it does not show
Only 51 patients were analysed, and all came from one hospital, so the findings may not apply elsewhere. The intervention was tested only for two months, so long-term effects are unknown. The intervention was a bundle of routine care, nurse-led team coordination, mobile app guidance, remote ECG monitoring, reminders, health education and counseling, so the effect of any single component cannot be separated. Height, weight and other indicators were not collected, which may introduce bias. Participants had first-time successful PCI and New York Heart Association class I-II, so more severe patients were not included. Blinding was described only as single-blind, so it is unclear who was blinded. The study listed several outcomes rather than one primary endpoint, so the positive findings should be read together rather than as evidence of one main effect.
Declared interests
The study was funded by The Scientific Reuter Foundation of Liaoning Provincial Education Department, China (grant LZ2020039). The authors declared no conflict of interest.
The easy way to misread this
Do not conclude that the mobile app alone caused the improvements. The intervention group also received routine care plus nurse-led multidisciplinary team management, mobile app guidance, remote ECG monitoring, daily reminders, health education and individual counseling, so the contribution of any single component cannot be separated.
