Impact of Lipid Profile, Cardiac Biomarkers, Serum Angiotensin-Converting Enzyme Activity, Oxidative Stress and Antioxidant on Blood Pressure Status
Abstract
The hemodynamic determinants of myocardial oxygen demand measured were heart rate (HR), systolic blood pressure (BP), and rate pressure product (RPP). This study aimed to evaluate the impact of lipid profile, cardiac biomarkers, and serum angiotensin-converting enzyme (ACE) activity, oxidative stress (plasma malondialdehyde, MDA; conjugated diene, DC), and antioxidant status (glutathione peroxidase, GPx) on BP. Three hundred and six non-ST-elevated myocardial infarction (NSTEMI) patients compared to 410 healthy controls. The diastolic and systolic BP was correlated positively with serum ACE activity. The rate pressure product (RPP) was correlated negatively with Fasting glucose (r= -0.144; p = 0.012), HbA1c (r= -0.117; p = 0.041) and GPx activity (r= -0.148; p = 0.009), and positively with smoking (r = 0,197; p = 0.001), BMI (r = 0,219; p = 0.001), peak cTnI (r = 0.131; p = 0.022), serum ACE activity (r = 0,190; p = 0.001) and DC level (r = 0.189; p = 0.001) in NSTEMI patients. Regarding healthy controls, no correlation was found between the diastolic or systolic BP with serum ACE activity, peak cTnI, MDA, DC level, GPx activity, and lipid parameters. The existence of a specific correlation between the rate pressure product, diastolic and systolic BP and, lipid profile, serum ACE activity and, cardiac biomarkers, oxidative stress, and antioxidant status increase the NSTEMI risk on patients.
