Prevalence of peripheral arterial disease in patients with heart failure with preserved ejection fraction

Abstract

OBJECTIVES:To describe the prevalence of the reduced ankle-brachial index (ABI) in patients with heart failure (HF) with preserved ejection fraction (HFpEF) attended at a HF clinic in the metropolitan region of Porto Alegre, and to compar the patients to those with reduced ejection fraction (HFrEF).METHODS:A descriptive observational study, included patients referred to the heart failure clinic in HU-Ulbra with HFpEF or HFrEF and diastolic dysfunction, and measurements of ABIs using vascular Doppler equipment were performed in both groups.RESULTS:The sample consisted of 106 patients with HF, 53.9% of the patients had HFpEF, and 19.4% had a diagnosis of peripheral arterial disease (PAD) (ABI less than 0.9). PAD was identified in 24.1% of the patients with HFpEF, while15.8% of patients in the HFrEF group were diagnosed with PAD.CONCLUSION:Our results did not identify a significantly different prevalence of altered and compatible PAD values in patients with HFpEF. However, we showed a prevalence of 19.4%, a high value if we consider similar populations.

“…Furthermore, the Colour Doppler echocardiography depicted an ejection fraction of less than 60% in most patients (67%), whereas 33% possessed an ejection fraction of more than 60%. Similarly, da Cunha et al 22 showed that, even though the incidence of PAD detection by ABI seemed to be significantly higher, about 19.4%, the difference was insignificant when patients were dichotomized by ejection fraction. Furthermore, various factors might clarify this phenomenon, including the distribution of IHD rates.…”
