Aim
Analysis of the cardioprotective effectivity of chronopharmacotherapy in patients with arterial hypertension (AH) after transient ischemic attack (TIA).
Material and methods
174 patients with AH and TIA were evaluated. All patients were randomized to three groups based on the dosing schedule of chronopharmacotherapy: group 1 (n=59), patients receiving indapamide retard 1.5 mg and valsartan 160 mg, both in the morning; group 2 (n=58), indapamide retard 1.5 mg in the morning and valsartan 160 mg in the evening; group 3 (n=57), indapamide retard 1.5 mg in the morning and valsartan 80 mg in the morning and evening. Echocardiography (EchoCG) (ALOKA SSD 2500, Japan) was performed for all patients at baseline and at 12 months of the treatment. Statistical analysis of results was performed with the Statistica 12.0 (StatSoftInc, USA) software.
Results
Before the treatment, EchoCG parameters did not significantly differ between the patient groups. After 12 months of the treatment, positive changes in the end-systolic dimension (ESD), interventricular septal thickness (IVST), thickness of the left ventricular posterior wall (TLVPW), LV myocardial mass (LVMM), LVMM index (LVMMI), ejection fraction (EF), ratio of transmitral early peak flow velocity and late filling flow velocity (E/A), and isovolumetric velocity relaxation time (IVRT) were more pronounced in the group of sartan evening dosing (group 2) than in the group of sartan single morning dosing (group 1) (p<0.05). In group 3, the changes in ESD, IVST, TLVPW, LVMM, LVMMI, EF, E/A ratio, deceleration time (DT) of LV, and IVRT were significantly greater than those in group 1, whereas the dynamics of ESD, IVST, TLVPW, LVMM, LVMMI, E/A ratio, and DT were better in group 3 than in group 2 (p<0.05). In addition, a significantly greater number of patients with normalized LV geometry was registered in group 3 compared to groups 1 and 2 (p<0.05). The number of patients with normal LV diastolic function after the treatment was also significantly greater in group 3 than in group 1 (p<0.05) and comparable with group 2.
Conclusion
The morning dosing of indapamide retard and the b.i.d. dosing of valsartan provided more pronounced beneficial changes in major EcoCG indexes and improvement of LV geometry and diastolic function than the sartan single dosing only in the morning or evening in combination with the diuretic.
