Safety of sacubitril/valsartan initiated during hospitalization: Data from a non‐selected cohort. ESC Heart Failure, 6(6), 1161–1166. https://doi.org/10.1002/ehf2.125272055-5822http://hdl.handle.net/11268/8839Aims Sacubitril/valsartan is safe when initiated during hospitalization in a clinical trial setting. Its safety in real‐life population is not stablished. We compared the initiation of sacubitril/valsartan during hospitalization in a non‐selected population, in the PIONEER‐HF trial, and in non‐selected outpatients. Methods and results Multicentre registry included 527 patients: 100 were started on sacubitril/valsartan during hospitalization (19.0%) and 427 as outpatients (81.0%). Compared with those in the pivotal trial, inpatients in our cohort were older (71 ± 12 vs. 61 ± 14 years; P < 0.001); had more frequently Functional Class II (41 [41.0%] vs. 100 [22.7%]; P < 0.001), higher levels of N‐terminal pro‐B type natriuretic peptide (4044 [1630–8680] vs. 2013 [1002–4132] pg/mL; P < 0.001), better glomerular filtration rate (63.5 [51.0–80.0] vs. 58.4 [47.5–71.5] mL/min; P = 0.01), and higher systolic blood pressure (121 [110–136] vs. 118 [110–133] mmHg; P = 0.03); and received angiotensin‐converting enzyme inhibitors/angiotensin receptor blockers more frequently (92 [92.0%] vs. 208 [52.7%]; P < 0.001). Compared with non‐selected outpatients, inpatients were older (71 ± 12 vs. 68 ± 12 years, P = 0.02), had more frequent Functional Class III–IV (58 [58.0%] vs. 129 [30.3%], P < 0.001), had higher levels of N‐terminal pro‐B type natriuretic peptide (4044 [1630–8680] vs. 2182 [1134–4172]; P < 0.001), and were receiving angiotensin‐converting enzyme inhibitors/angiotensin receptor blockers target dose less frequently (55 [55.0%] vs. 335 [78.5%]; P < 0.001). They also started sacubitril/valsartan with a low dose (50 mg/12 h) more frequently (80 [80.0%] vs. 209 [48.8%], P < 0.001). The initiation of sacubitril/valsartan in outpatients was an independent predictor of high‐dose use (OR 3.1; 95% confidence interval 1.7–5.6, P < 0.001). The follow‐up time in both cohorts, including all patients enrolled, was similar (7.0 ± 0.1 vs. 7.2 ± 2.6 months, P = 0.72). All‐cause admissions during follow‐up were more frequent in inpatients (30 [30.0%] vs. 68 outpatients [15.9%], P = 0.001), with no relevant differences in all‐cause mortality. There was no significant difference in sacubitril/valsartan withdrawal rate (17 inpatients [17.0%] vs. 49 outpatients [11.5%], P = 0.13). The incidence of adverse effects was also similar: hypotension (16 inpatients [16.0%] vs. 71 outpatients [16.7%], P = 0.88), worsening renal function (7 inpatients [7.0%] vs. 29 outpatients [6.8%], P = 0.94), and hyperkalaemia (1 inpatient [1.0%] vs. 21 outpatients [4.9%], P = 0.09). We did not register any case of angioedema. Conclusions It is safe to initiate sacubitril/valsartan during hospitalization in daily clinical practice. Inpatients have a higher risk profile and receive low starting doses more frequently than outpatients.engSafety of sacubitril/valsartan initiated during hospitalization: Data from a non‐selected cohortjournal article10.1002/ehf2.12527restricted accessHospitalesEnfermos cardíacosMedicamentos cardiovascularesHospitalEnfermedad cardiovascularMedicamento
