CLINICAL AND ECONOMIC IMPACT OF NON-INVASIVE RISK STRATIFICATION ON ACUTE THORACIC DOR: A LITERATURE REVIEW

Abstract

The general objective of this study is to analyze the clinical and economic impact of non-invasive risk stratification in the evaluation of patients with acute thoracic pain, based on evidence available in the scientific literature. For this reason, a qualitative bibliographic review was carried out, with an exploratory and analytical-interpretive approach. The search was conducted on reconstructed data bases, using descriptors related to acute thoracic pain, clinical risk scores, highly sensitive troponin and cost-effectiveness. These include clinical trials, systematic reviews and economic analysis studies that present a direct relationship with the proposed topic, with the data organized in clinical and economic cases for subsequent critical synthesis. A discussion has shown that the use of structured protocols, such as the HEART Pathway, associated with the application of high-sensitivity troponin, allows for the safe identification of low-risk patients who choose early discharge, maintaining low rates of adverse cardiovascular events. Furthermore, the literature demonstrates a significant reduction in unnecessary hospitalizations, shorter hospital stays and rationalization of the use of complementary examinations and specialized literature. From an economic perspective, the analyzed studies indicate a favorable profile of cost-effectiveness, with reduced direct expenses and better allocation of resources in emergency services. It is concluded that non-invasive risk stratification constitutes a clinically safe and economically sustainable strategy in the approach to acute thoracic pain, contributing to care efficiency without compromising the quality of care.
