Heart failure is a complex entity, with high morbidity and mortality. The clinical course and outcome are uncertain and difficult to predict. This document, instigated by the Heart Failure and Geriatric Cardiology Working Groups of the Spanish Society of Cardiology, addresses various aspects related to palliative care, where most cardiovascular disease will eventually converge. The document also establishes a consensus and a series of recommendations with the aim of recognizing and understanding the need to implement and progressively apply palliative care throughout the course of the disease, not only in the advanced stages, thus improving the care provided and quality of life. The purpose is to improve and adapt treatment to the needs and wishes of each patient, who must have adequate information and participate in decision-making.

Background A do-not-resuscitate (DNR) order is a medical decision that instructs healthcare providers to withhold cardiopulmonary resuscitations (CPR) to patients in case of cardiopulmonary arrest in respect to their wishes. In Saudi Arabia, the decision is usually made by physicians based on the Fatwa number 12086 regardless of the patients\' or their families\' desires. Assessing the knowledge, perception, and attitude of Saudi family members towards this medical decision may help guide medical practitioners to make decisions that are legally and ethically acceptable for the patients and their family. Therefore, this study aimed to assess their knowledge, perception, and attitude about DNR decisions and to determine demographic variables that affect their attitude towards DNR decisions. Method This cross-sectional study was conducted from December 2017 to January 2018 utilizing survey distribution through emails and different social media outlets including Facebook, Twitter, Pinterest, and LinkedIn. A self-administered questionnaire was employed to elicit responses regarding knowledge, perception, and attitude towards DNR decisions. Statistical Package for the Social Sciences Windows version 17 (SPSS v.17) (IBM Corporation, USA) was used for data management and analysis. Result Of the 1882 participants who filled the questionnaire, only 1693 participants were eligible as the study sample population and were included in the final data analysis. Most of the participants were from the Makkah region (72.2%) and were mainly from the general population (61.66%). Participants were mainly females (66%) and within the median age of 30 years (IQR: 21). As expected, participants who had heard about the DNR practice were from the medical field (58.6%) and they were mainly distant relatives. Almost 76% of the participants had two to four incorrect answers about the DNR practice, and it indicated that participants have inadequate knowledge about a DNR order. Most of the participants (43.2%) refused to be on a DNR order if they were diagnosed with a terminal illness. However, most participants (69.9%) wanted to have an involvement in the decision-making of being on a DNR order. In terms of willingness to understand and learn about the DNR decision, 1475 (87.1%) of the participants wanted to learn more about the DNR practice. Being a relative of a terminally ill cancer patient did not have a significant effect on the knowledge and perceptions of participants about being on a DNR order. However, having a background in medicine was found to be significantly associated with their acceptance to be on a DNR order. The knowledge score regarding DNR was found to be significantly associated with higher acceptance towards DNR orders. Conclusion The majority of participants had a lack of knowledge about the DNR practice. Their religion\'s concept of hope and virtue is considered as the major reason for their DNR order refusal. However, proper education about the DNR practice and involvement in the DNR order decision-making will increase the participants\' knowledge and will improve their acceptance of the DNR practice.

OBJECTIVE: The do not resuscitate (DNR) order is a decision taken by the patient or other people about medical care in the end stages of life to prevent resuscitation from causing cardiac or respiratory arrest. This study was conducted to evaluate the attitudes of patients\' relatives in the end stages about DNR order.
METHODS: In a cross-sectional study, 150 relatives of patients who had been prescribed DNR orders were included in the educational hospitals affiliated to the Kermanshah University of Medical Sciences. The data collection tool was a researcher-developed questionnaire consisting of 29 attitudes questions related to DNR orders. The data were collected and analyzed in the SPSS software version 19 using descriptive tests.
RESULTS: According to the results of present study, although the relatives of pationts consider doctors thoroughly responsible for making decision related with DNR, and follow their order either way, they strongly disagree with a single doctor making individual decision in this domain. They believe that the patient and their relatives should be engaged in this decision. Although most participants tended to stay as close as possible to the patients and engage in patient care.
CONCLUSIONS: Given that there are a few studies in Iran on the attitudes of patients and their relatives about DNR, and there are no specific rules and guidelines in this regard. It is recommended that further studies be conducted on the subject. Engaging of patients and families in this important decision is necessary.

With the enactment of the \'Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life\' (Act No. 14013) in Korea, there is growing concern about the practicality of this law. In this review, we discuss definitions, ethics, and practical issues related to this law.
