Emergency Department Triage of Patients With Acute Chest Pain Based on the ESC 0/1-hour Algorithm (PRESC1SE-MI)

The PRESC1SE-MI study compares two algorithms for triage of patients presenting with chest pain and symptoms of heart attack (myocardial infarction) to the emergency department. Both algorithms are recommended by the European Society of Cardiology: the 0/3-hour algorithm and the 0/1-hour algorithm. Currently, most emergency departments worldwide use the 0/3-hour troponin algorithm. Cardiac troponin (cTn) is a heart-specific biomarker which indicates damage of the heart muscle and which increases after a heart attack. In the 0/3-hour algorithm, the amount of troponin in the bloodstream is measured with a high-sensitivity assay at admission and 3 hours thereafter. Likewise, the 0/1-hour algorithm means that the blood sample in which the troponin is measured is collected at admission and 1 hour later. Since recent clinical studies suggest that the 0/1-hour algorithm is superior to the 0/3-hour algorithm, many hospitals consider switching to the 0/1-hour algorithm. The aim of this study is to assess how feasible the time-saving 0/1-hour algorithm would be in reality and whether it provides the same accuracy and safety in the diagnosis of myocardial infarction as the current practice the 0/3-hour algorithm.

Intravenous Hydromorphone for the Treatment of Acute Pain

To observe the efficacy and safety of hydromorphone in the treatment of acute chest pain, and to explore the potential advantages of hydromorphone for analgesia in patients with acute chest pain, so as to provide more theoretical basis for individualized analgesia and rapid recovery in patients with acute chest pain.

Clinical Profile, Management Strategies, And Outcome Of Patients With Acute Chest Pain In Regional Referral Hospitals In Tanzania. Protocol For A Prospective, Multi-Centre Cohort Study

This study aims to understand how patients with acute chest pain are evaluated, treated, and cared for in emergency departments (EDs) at regional hospitals in Tanzania. Chest pain can be caused by many conditions, some of which are life-threatening, like heart attacks (acute coronary syndrome, or ACS). In Tanzania and other low-resource settings, delays in diagnosis and treatment can lead to poor outcomes. This study will document current practices, identify challenges, and link these findings to patient outcomes (e.g., survival, complications) to improve care for future patients. \- Participants: Adults (18 years or older) who come to the ED with chest pain or suspected acute coronary syndrome (heart problem) at the regional referral hospitals in Dar es Salaam, Tanzania. Three regional referral hospitals and one specialized cardiac hospital (Jakaya Kikwete Cardiac Institute) will be involved in this study. Research assistants will collect data during routine care. During the study, i. Enrollment will take place over 12 months; 317 patients with chest pain will be invited to participate. ii. Researchers will record: * How quickly patients receive initial diagnostic tests (e.g., ECG, blood tests for heart damage). * Treatments given (e.g., medications, procedures to restore blood flow to the heart). * Patient outcomes over 30 days (e.g., survival, readmission to the hospital, complications like another heart attack or stroke). iii. Follow-up: Patients will be contacted by phone 30 days after their ED visit to check their health status. This study is important because-: Chest pain is a common reason for ED visits, but in Tanzania, many patients face delays in diagnosis or lack access to lifesaving treatments. This study will identify gaps in care to help hospitals improve emergency services. Understanding the challenges in chest pain care can empower families to advocate for timely treatment for their loved ones. For Healthcare Providers: The findings will guide hospitals in adopting better protocols (e.g., faster ECGs, improved use of medications) and allocating resources effectively. For Policymakers: Results can inform national strategies to reduce deaths from heart disease in Tanzania. During the study, participants should know that there will be no changes to care; patients will receive the same care they would normally get. The study only observes and records what happens. Personal information will be kept confidential, and data will be anonymized (no names or identifiers used). Participation is voluntary, and patients can choose to join or refuse without affecting their care. Key Questions the Study Will Answer 1. How quickly do patients with chest pain get critical tests (like ECGs) and treatments in Tanzanian hospitals? 2. What are the most common barriers to timely care (e.g., lack of equipment, training gaps)? 3. What percentage of patients survive 30 days after a chest pain episode, and what factors influence their outcomes? Potential Benefits * Improved Care: Findings may lead to better hospital protocols. * Resource Allocation: Highlight where hospitals need more tools (e.g., ECG machines) or medications * Global Impact: Lessons from Tanzania can help other low-resource countries improve emergency heart care. Ethical Considerations * Approval: The study has been reviewed and approved by ethics committees to ensure patient safety and rights. * Informed Consent: Participants (or their families, if critically ill) will be asked for permission before joining. How will results be shared-: Findings will be published in medical journals and shared with Tanzanian hospitals, health officials, and global organizations to drive improvements in emergency care.
