To explore whether a condition of severe heart failure results in alteration of the 24-h-blood pressure (BP) profile and BP circadian rhythm, 19 patients with severe heart failure (NYHA class III-IV, 17M, 2F, mean age 57 ± 8 years) were considered and compared to a control group of age- and sex-matched normal subjects. All subjects were submitted to non-invasive 24- h ambulatory blood pressure monitoring using a SpaceLabs 90207 unit (recording interval 15 min). Both systolic and diastolic BP profiles were evaluated using the two-step method of analysis reported by Staessen: the existence of a BP circadian rhythm was first tested using Siegel's runs test, then a Fourier multiple harmonic analysis allowed us to obtain the BP profile parameters Acrophases (Acro, hh:mm) and Amplitudes (Ampl, mmHg). The same methods were used for pulse rate. Our results showed the presence of a BP circadian rhythm in severe heart failure subjects, as well as in control subjects. Furthermore, no significant difference was found between the two groups when considering the BP profile parameters Acro and Ampl. In conclusion, in contrast with previous reports, our results show that both BP circadian rhythm and BP profile parameters are preserved in patients with severe heart failure.

Abstract

To explore whether a condition of severe heart failure results in alteration of the 24-h-blood pressure (BP) profile and BP circadian rhythm, 19 patients with severe heart failure (NYHA class III-IV, 17M, 2F, mean age 57 ± 8 years) were considered and compared to a control group of age- and sex-matched normal subjects. All subjects were submitted to non-invasive 24- h ambulatory blood pressure monitoring using a SpaceLabs 90207 unit (recording interval 15 min). Both systolic and diastolic BP profiles were evaluated using the two-step method of analysis reported by Staessen: the existence of a BP circadian rhythm was first tested using Siegel's runs test, then a Fourier multiple harmonic analysis allowed us to obtain the BP profile parameters Acrophases (Acro, hh:mm) and Amplitudes (Ampl, mmHg). The same methods were used for pulse rate. Our results showed the presence of a BP circadian rhythm in severe heart failure subjects, as well as in control subjects. Furthermore, no significant difference was found between the two groups when considering the BP profile parameters Acro and Ampl. In conclusion, in contrast with previous reports, our results show that both BP circadian rhythm and BP profile parameters are preserved in patients with severe heart failure.
