AIM: Renal dysfunction is a common comorbidity in patients with heart failure and
preserved ejection fraction (HFpEF). We sought to determine whether renal
dysfunction was associated with measures of cardiovascular structure/function in
patients with HFpEF. METHODS: We studied 217 participants from the PARAMOUNT
study with HFpEF who had echocardiography and measures of kidney function. We
evaluated the relationships between renal dysfunction [estimated glomerular
filtration rate (eGFR) >30 and <60 mL/min/1.73 m(2) and/or albuminuria] and
cardiovascular structure/function. RESULTS: The mean age of the study population
was 71 years, 55% were women, 94% hypertensive, and 40% diabetic. Impairment of
at least one parameter of kidney function was present in 62% of patients (16%
only albuminuria, 23% only low eGFR, 23% both). Renal dysfunction was associated
with abnormal LV geometry (defined as concentric hypertrophy, or eccentric
hypertrophy, or concentric remodelling) (adjusted P = 0.048), lower midwall
fractional shortening (MWFS) (P = 0.009), and higher NT-proBNP (P = 0.006).
Compared with patients without renal dysfunction, those with low eGFR and no
albuminuria had a higher prevalence of abnormal LV geometry (P = 0.032) and lower
MWFS (P < 0.01), as opposed to those with only albuminuria. Conversely,
albuminuria alone was associated with greater LV dimensions (P < 0.05). Patients
with combined renal impairment had mixed abnormalities (higher LV wall
thicknesses, NT-proBNP; lower MWFS). CONCLUSION: Renal dysfunction, as determined
by both eGFR and albuminuria, is highly prevalent in HFpEF, and associated with
cardiac remodelling and subtle systolic dysfunction. The observed differences in
cardiac structure/function between each type of renal damage suggest that both
parameters of kidney function might play a distinct role in HFpEF.
