Insights
Serum prolidase activity is lower in hypertensive patients, correlating with hypertension presence and duration. This enzyme
Area of Science:
- Biochemistry
- Cardiology
- Clinical Medicine
Background:
- Hypertension is a major cardiovascular risk factor.
- Left ventricular hypertrophy (LVH) is a common complication of hypertension.
- The role of serum prolidase activity in hypertension and LVH requires further investigation.
Purpose of the Study:
- To determine serum prolidase activity in patients with hypertension.
- To investigate the relationship between serum prolidase activity and left ventricular hypertrophy in hypertensive patients.
Main Methods:
- Serum prolidase activity was measured spectrophotometrically.
- Participants were divided into three groups: controls, hypertensive patients with LVH, and hypertensive patients without LVH.
- Statistical analyses included ANOVA and multivariate analysis.
Main Results:
- Serum prolidase activity was significantly lower in the control group compared to hypertensive groups.
- Prolidase activity showed a significant correlation with the presence and duration of hypertension.
- Prolidase activity was not significantly correlated with left ventricular mass index.
Conclusions:
- Serum prolidase activity is associated with hypertension.
- This association is independent of left ventricular hypertrophy.
- Serum prolidase may serve as a potential biomarker in hypertension management.
Objectives:
The purpose of this study was to determine serum prolidase activity in patients with hypertension and its relation with left ventricular hypertrophy.
Design And Methods:
Serum prolidase activity was measured spectrophotometrically in hypertensive patients with (Group II, n=30) and without left ventricular hypertrophy (Group III, n=30) and in control group (Group I, n=30).
Results:
Prolidase activity was significantly lower in Group I than in Groups II and III (44.64+/-6.42 U/L vs. 54.14+/-6.30 U/L and 54.25+/-7.14 U/L, respectively; ANOVA, p<0.001). We revealed significant correlation between prolidase activity and presence and duration of hypertension (both of p<0.05) but not left ventricular mass index. Multivariate analysis shown that prolidase activity was significantly associated with age (beta=0.481, p<0.001) and duration of hypertension (beta=0.396, p<0.001).
Conclusions:
Our data show that serum prolidase activity is associated with the presence hypertension independent of left ventricular hypertrophy.
