Evaluation of the effectiveness of statin and spironolactone by the influence on indicators of vascular stiffness in patients with arterial hypertension

Abstract

Abstract Introduction The possibility of slowing down vascular remodeling in hypertensive patients with the combined effect of antihypertensive drugs and statins has been studied in unitary studies. The effect of spironolactone on vascular stiffness in relation to the severity of the hypotensive effect in combination therapy has also been insufficiently studied. The aim of the research was to study the dynamics vascular stiffness parameters in hypertension patients of high/very high cardiovascular risk in addition rosuvastatin or spironolactone to combined two-component amlodipine and lisinopril therapy. Methods 90 patients (46 men and 44 women aged 51.6±8.5) with hypertension were randomized into groups: the first group received a fixed combination of amlodipine/lisinopril, the 2nd one followed the same regimen of therapy with addition of 20 mg rosuvastatin, the third - in addition to the combination of amlodipine / lisinopril received 25 mg of spironolactone. The office and ambulatory blood pressure (BP), central (aortic) BP, augmentation index (AIx), carotid-femoral and carotid-radial pulse wave velocity (PWV) were evaluated before and after a 24-week follow-up period. Results The office and average daily blood pressure decreased against the background of all therapy regimens (all p<0.0001). The degree of decrease in the above parameters was more pronounced under the influence of spironolactone, compared with taking a combination of amlodipine / lisinopril (office systolic BP (SBP) p=0.04 and diastolic BP (DBP) p=0.002, average daily SBP p=0.02 and DBP p=0.014) and office DBP in comparison with the group of additional administration of rosuvastatin (p=0.02). A decrease in central BP and AIx was noted in all groups. A more pronounced decrease in AIx occurred in the statin supplementation group relative to the standard treatment group (−5.8% and −9.0%, respectively, p=0.036). Carotid-femoral PWV significantly decreased in all groups (−0.9±1.5 m/s, −0.7±1.4 m/s, −2.2±2.6 m/s, respectively), in greater degree in the spironolactone addition group compared with the statin supplementation group (p=0.036). Carotid-radial PWV to the same extent significantly decreased only in the second (from 9.5±1.8 to 8.8±1.1 m/s (p=0.034)) and the third (from 9.8±1.3 to 8.4±1.3 m/s (p=0.0002)) groups. Conclusions The addition of a statin to a two-component combination of amlodipine / lisinopril in the treatment of hypertensive patients had an additional effect on the elastic properties of the aorta, in the form of a decrease in the augmentation index, and peripheral arteries, in the form of a decrease in PWV. The addition of spironolactone to standard therapy was accompanied by a significant increase in the antihypertensive effect and a decrease in aortic stiffness in the form of a more pronounced decrease in PWV in the carotid-femoral and carotid-radial areas.
