Facilitating supportive care in cardiac intensive care units

The number of patients who die in the hospital in the Western world is high, and 20-30% of them are admitted to an ICU in the last month of life, including those in cardiac ICUs (CICUs) where invasive procedures are performed and mortality is high. Palliative consultation is provided in only a few cases. The ethical and decisional aspects associated with the advanced stages of illness are very rarely discussed.

The epidemiological and clinical landscape of CICUs has changed in the last decade; the incidence of acute coronary syndromes has decreased, whereas noncardiovascular diseases, comorbidities, the patients' age and clinical and therapeutic complexity have increased. The use of advanced and invasive treatments, such as mechanical ventilation, mechanical circulatory support and renal replacement therapies, has increased. This evolution increases the possibility of developing a life-threatening clinical event.

This review aimed to analyze the main epidemiological, clinical, ethical and training aspects that can facilitate the introduction of supportive/palliative care programs in the CICU to improve symptom management during the advanced/terminal stages of illness, and address such issues as advance care planning, withdrawing/withholding life-sustaining treatments, deactivation of implantable defibrillators and palliative sedation.
