Key result
Essential hypertension is linked to ~53% higher MMP-1 levels versus normotensive controls.
Why the study?
MMPs and TIMPs are thought to be actively involved in cardiovascular extracellular matrix remodeling during hypertensive damage, but serum MMP-1 and TIMP-1 levels in essential hypertension needed evaluation.
Observational (n=80)
No
Absolute Event Rate: 1.82% vs 1.19%
p-value: p=0.03
Elevated serum levels of MMP-1 and TIMP-1 in patients with essential hypertension suggest increased extracellular matrix remodeling and potential for cardiovascular fibrosis.
Does not support clinical MMP-1/TIMP-1 testing in hypertension; hypothesis-generating for matrix remodeling research pending prospective validation.
Hypertension (HTN) is a leading risk factor for cardiovascular (CV) disease. Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are thought to be actively involved in the remodeling of the CV extracellular matrix (ECM) during hypertensive damage. Therefore, in this study, we aimed to investigate serum levels of MMP-1 and TIMP-1 in patients with essential HTN and compare them with those of normotensive individuals. We measured serum concentrations of MMP-1 and TIMP-1 in 60 patients with HTN and 20 healthy controls using an ELISA. The obtained results showed that in patients with HTN, the mean levels of MMP-1 (1.82 ± 0.9 ng/mL) were significantly higher (p = 0.03) than the mean levels in the control group (1.19 ± 0.7 ng/mL). The levels of TIMP-1 in patients with essential HTN (0.44 ± 0.1 ng/mL) were also significantly higher (p = 0.005) than those in the control group (0.33 ± 0.1 ng/mL). In HTN, elevated serum MMP-1 levels may be associated with increased collagen degradation in the CV ECM, whereas elevated TIMP-1 levels may favor its accumulation and the development of pathological remodeling and fibrosis of the heart and arterial vessels.

Kostov et al. (2022) conducted an observational in Essential Hypertension (n=80). Essential hypertension vs. Normotensive individuals was evaluated on Serum levels of MMP-1 (p=0.03). Patients with essential hypertension had significantly higher mean serum levels of MMP-1 (1.82 vs 1.19 ng/mL, p=0.03) and TIMP-1 (0.44 vs 0.33 ng/mL, p=0.005) compared to normotensive controls.
