Objective:

The aim of this study is to describe the characteristics and clinical behaviour of patients treated with sacubitril/valsartan in a heart failure clinic of a high complexity hospital.

Methods:

A retrospective analysis was performed on a total of 56 patients on treatment with sacubitril/valsartan, between January 2017 and May 2018. At three months from the start of the treatment, 87% of the patients were evaluated. Changes were observed in functional class, left ventricular ejection fraction (LVEF), and systolic and diastolic arterial pressure. A record was made of hospital re-admissions due to heart failure, cardiovascular mortality, and adverse events associated with the medication.

Results:

The mean age of the patients was 71.3 years, of which 51.7% were male. An ischaemic origin was found in 73%. NYHA II and NYHA III functional class was observed 35% and 60%, respectively, before starting the treatment with sacubitril/valsartan. At the end of follow-up, 57% improved their functional class, and 81.7% were found to be in NYHA II functional class (95% CI; -0.52 to -0.18:=0.0002). There was a significant improvement in the LVEF values compared to baseline (95% CI; 4.27 to 11.86; P=0.0002). A significant decrease was observed in both systolic and diastolic blood pressure (P<0.01). There was sudden death in one (2%) patient and one (2%) patient admitted due to heart failure. None of the patients stopped the therapy due to secondary effects.

Conclusion:

Sacubitril/valsartan is a useful therapy in patients with symptomatic heart failure and a decreased LVEF. The population evaluated had a demographic and similar clinical signs and symptoms to the PARADIGM-HF clinical trial, which suggests that the clinical outcomes are similar in the Colombian population.
