In the STRONG-HF trial, non-cardiac comorbidities neither limited the rapid up-titration of HF therapies, nor attenuated the benefit of high-intensity care on the primary endpoint.
Aims: To assess the potential interaction between non-cardiac comorbidities (NCCs) and the efficacy and safety of high-intensity care (HIC) versus usual care (UC) in the STRONG-HF trial, including stable patients with improved but still elevated natriuretic peptides.Methods and results: In the trial, eight NCCs were reported: anaemia, diabetes, renal dysfunction, severe liver disease, chronic obstructive pulmonary disease/asthma, stroke/transient ischaemic attack, psychiatric/neurological disorders, and malignancies. Patients were classified by NCC number (0, 1, 2 and >= 3). The treatment effect of HIC versus UC on the primary endpoint, 180-day death or heart failure (HF) rehospitalization, was compared by NCC number and by each individual comorbidity. Among the 1078 patients, the prevalence of 0, 1, 2 and >= 3 NCCs was 24.3%, 39.8%, 24.5% and 11.4%, respectively. Achievement of full doses of HF therapies at 90 and 180 days in the HIC was similar irrespective of NCC number. In HIC, the primary endpoint occurred in 10.0%, 16.6%, 13.6% and 26.2%, in those with 0, 1, 2 and >= 3 NCCs, respectively, as compared to 19.1%, 25.4%, 23.3% and 26.2% in UC (interaction-p = 0.80). The treatment benefit of HIC versus UC on the primary endpoint did not differ significantly by each individual comorbidity. There was no significant treatment interaction by NCC number in quality-of-life improvement (p = 0.98) or the incidence of serious adverse events (p = 0.11).Conclusions: In the STRONG-HF trial, NCCs neither limited the rapid up-titration of HF therapies, nor attenuated the benefit of HIC on the primary endpoint. In the context of a clinical trial, the benefit-risk ratio favours the rapid up-titration of HF therapies even in patients with multiple NCCs.
