Acute renal failure (ARF) is a syndrome that occurs due to multiple causes of injury and is characterized by an abrupt decrease in glomerular filtration rate. The concept of renal angina is made to highlight the characteristics of renal injury, as an analogy to the concept of angina pectoris, which is used to increase the suspicion of acute coronary syndrome in cardiology.
Material and methods: Prospective, observational and descriptive study. The present study will be carried out on patients admitted and attended in the Emergency Department of the Hospital de Alta Especialidad (UMAE) No. 14. Adolfo Ruiz Cortínez from September 1 to November 30, 2022. The data described in the data collection instrument will be collected in order to later concentrate them in a database for analysis.
Results: Of the 73 patients who entered the study, 42 patients were male, the mean age was 55 years, the minimum 18 and the maximum 75, the mode was 70 years. Of the patients included 49 were diabetic and of these 38.36% were male, only 11 had sepsis without much difference between the two sexes, representing 15.07% of the total number of patients. Of the total number of patients only 12 were admitted to the intensive care unit, 16.44%; the male sex was the most prevalent group, only 23.9% of the total number of patients required mechanical ventilation and 10.96% required vasopressor (Of the total number of patients only 15 (20.5%) had acute renal injury and of these the most affected age group was 61 to 80 years old).
Conclusion: The percentage of patients with a positive renal angina index (>8) who had AKI was 100% of the 73 patients only 15 developed AKI. Sepsis, vasopressor use and mechanical ventilation did not have a significant value for the development of AKI within this study in comparison to the study “Renal angina: “The beginning of the end” where out of 95 patients included in their study, sepsis, vasopressor use and mechanical ventilation did have a significant value for the development of AKI.
