Abstract

Introduction. Valvular heart diseases (VHD) increase the risk of cardiovascular morbidity and mortality. Little is known about the correlation between circadian blood pressure profile (CBPP) and VHD. The study aimed to clarify the association between CBPP and VHD prevalence. Material and methods. 103 consecutive patients (male: 50.5%), who underwent 24-hour ambulatory blood pressure measurement (ABPM) and Holter electrocardiography simultaneously were analysed. Patients were divided into 3 groups: dipping was defined as 10–20% (28.2%), non-dipping as < 10% (50.5%) fall in nocturnal blood pressure (BP) and reverse-dipping as higher nocturnal than diurnal BP (21.4%). VHD was assessed by transthoracic echocardiography and described as mild, moderate or severe regurgitation or stenosis accordingly. Further, the severity of VHD, nocturnal fall pattern and ABPM features in all groups were compared. Results. The authors found no statistically significant association between severity of VHD and dipping status. The presented study showed some correlations between VHD severity and different ABPM parameters. Conclusions. Though severity of VHD did not influence dipping status obtained by ABPM, there were associations between VHD and ABPM outcomes. Further studies are needed.
