Key result

Vitamin D and catechin prevent diabetic cardiomyopathy progression in rats by reducing oxidative stress and fibrosis.

n=50

Why the study?

This study aimed to evaluate the cardioprotective effects of Vitamin D and Catechin against diabetic cardiomyopathy in a rat model, specifically focusing on attenuating cardiac fibrosis.

Does Vitamin D and Catechin improve diabetic cardiomyopathy in a rat model?

Population

Implication

Should not yet change practice; leaves open efficacy of Vitamin D and catechin in human diabetic cardiomyopathy.

Key Points

The aim is to assess the protective effects of Vitamin D and Catechin against diabetic cardiomyopathy, focusing on cardiac fibrosis.
Induced type 2 diabetes in male Sprague–Dawley rats using a high-fat diet and streptozotocin.
Divided rats into five groups: control, diabetic, Vitamin D-treated, Catechin-treated, and combination-treated.
Administered Vitamin D (500 IU/kg) and Catechin (400 mg/kg) orally until study completion.
Measured heart function, glucose levels, cardiac injury biomarkers, and oxidative stress markers.
Determined expression levels of TGF-β1 and SMAD2/3/4 mRNA using reverse transcriptase PCR.
Diabetic cardiomyopathy caused significant disturbances in all measured parameters.
Treatment with Vitamin D and Catechin improved heart function and reduced glucose and lipid levels.
Observed reduction in oxidative stress and cardiac fibrosis in treated groups.
Lowered expression of TGF-β1 and SMAD2/3/4 in cardiac tissues was noted.
Decreased MMP-9 activity was associated with treatment.

Does Vitamin D and Catechin improve diabetic cardiomyopathy in a rat model?

Population

50 male Sprague-Dawley rats with type 2 diabetes induced by high-fat diet and streptozotocin (diabetic cardiomyopathy model)

Intervention

Vitamin D (500 IU/kg) and Catechin (400 mg/kg) orally, alone or in combination

Comparator

Control group and untreated diabetic cardiomyopathy group

Outcome

Cardiac fibrosis, heart function, glucose levels, cardiac injury biomarkers, oxidative stress markers, TGF-β1 and SMAD2/3/4 mRNA expression, and MMP-9 activitysurrogate

Vitamin D and Catechin demonstrate cardioprotective effects against diabetic cardiomyopathy in a rat model by targeting the TGF-β1/SMAD pathway and MMP-9 activity.

Elnaggar et al. (2026) studied Diabetic cardiomyopathy (n=50). Vitamin D and Catechin vs. Control and untreated DCM groups was evaluated on Heart function, glucose levels, cardiac injury biomarkers, oxidative stress markers, and cardiac fibrosis. Vitamin D and Catechin treatment prevented diabetic cardiomyopathy progression in rats by lowering blood sugar, reducing oxidative stress, and inhibiting fibrosis and MMP-9 activity.
