Insuficiencia cardíaca

Why / when / how

Nutritional intervention in heart failure could improve quality of life and symptoms, with an uncertain effect on cardiovascular events and mortality. The certainty of the evidence in the critical outcomes is very low. This is why the recommendation is conditional and weak in favor: the balance between benefits and harms is uncertain, with a possible symptomatic benefit that supports a suggestion, not a strong recommendation.

Cautions

Before indicating nutritional changes, assess the patient's nutritional status, comorbidities, and treatments, and individualize the intervention according to their clinical condition. Carry out a screening for eating disorders and consider the possible interactions between food and the medications in use. Advise seeking professional assessment if any of these warning signs appear: involuntary weight loss, persistent digestive symptoms, decompensation of an underlying disease; and refer to a nutrition professional; where more appropriate, to the corresponding specialist when the situation requires it. Reassess the response and the tolerance periodically.
