Why the study?
Non-invasive mechanical ventilation in chronic heart failure carries risks and complications that require individualization and close monitoring, particularly with coexisting ischaemic heart disease, arterial hypotension, or servo ventilation.
NIMV in chronic heart failure must be carefully individualized due to risks of hypotension, and adaptive servo ventilation should be avoided in HFrEF due to increased mortality.
Supports caution with NIMV due to hypotension risk and ASV avoidance in HFrEF with central sleep apnea; leaves open need for randomized confirmation.
Non-invasive mechanical ventilation (NIMV) is a therapeutic procedure that aims to supplement or improve ventilatory function. In recent decades, its benefit and multiple indications, have been demonstrated in the treatment of patients with chronic heart failure (CHF) and its acute complications [1]. However, the use of this therapy, in patients with chronic heart failure is not exempt from risks and complications, so it must be carefully individualized and requires close monitoring when ischaemic heart disease and/or arterial hypotension also coexist. Special mention requires the revision of the indication of servo ventilation in patients with severe chronic heart failure, due to its possible adverse effects.
