Key finding

Mean between-group difference in the complete-case analysis was -0.13% (95% CI, -0.25 to -0.01), P = 0.04.

A home-based lifestyle intervention with telemedicine support showed modest effects on HbA1c levels in patients with coronary heart disease and type 2 diabetes.

Plain-language summary

What this paper says

A plain-language read of the study’s main message and where it applies.

Study focus

A home-based lifestyle intervention with telemedicine support showed modest effects on HbA1c levels in patients with coronary heart disease and type 2 diabetes.

Clinical relevance

Improving glycemic control is crucial for patients with CHD and T2DM, as it may reduce the risk of complications. While the intervention showed a modest effect on HbA1c, the lack of significant impact on cardiovascular events highlights the need for comprehensive strategies in managing these patients.

Keep in mind

The study had a modest sample size, which may limit the generalizability of the findings. The intervention's long-term effects beyond 12 months were not assessed. The statistical significance of some outcomes was not achieved, indicating uncertainty in effectiveness.

Efectos Principales

The lifestyle intervention reduced HbA1c by -0.13% (95% CI, -0.25 to -0.01), P = 0.04.

At 12 months, 31 patients (6.2%) experienced a major adverse cardiovascular event; P = 0.15.

Hospitalizations for angina or revascularization were higher in the lifestyle intervention group (n = 15) compared to usual care (n = 8).
