AIM: The aim of the study is to determine whether the apparent benefit of revascularization of renal artery stenosis for 'flash' pulmonary oedema extends to heart failure patients without a history of prior acute pulmonary oedema.
METHODS: A prospective study of patients with renal artery stenosis and heart failure at a single centre between 1 January 1995 and 31 December 2010. Patients were divided into those with and without previous acute pulmonary oedema/decompensation. Survival analysis compared revascularization versus medical therapy in each group using Cox regression adjusted for age, estimated glomerular filtration rate, blood pressure and co-morbidities.
RESULTS: There were 152 patients: 59% male, 36% diabetic, age 70 ± 9 years, estimated glomerular filtration rate 29 ± 17 mL/min per 1.73 m2 ; 52 had experienced previous acute pulmonary oedema (34%), whereas 100 had no previous acute pulmonary oedema (66%). The revascularization rate was 31% in both groups. For heart failure without previous acute pulmonary oedema, the hazard ratio for death after revascularization compared with medical therapy was 0.76 (0.58-0.99, P = 0.04). In heart failure with previous acute pulmonary enema, the hazard ratio was 0.73 (0.44-1.21, P = 0.22). For those without previous acute pulmonary oedema, the hazard ratio for heart failure hospitalization after revascularization compared with medical therapy was 1.00 (0.17-6.05, P = 1.00). In those with previous acute pulmonary oedema, it was 0.51 (0.08-3.30, P = 0.48).
CONCLUSION: The benefit of revascularization in heart failure may extend beyond the current indication of acute pulmonary oedema. However, findings derive from an observational study.
