Acute Coronary Syndrome III: Diagnostic Studies

200
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

769
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

744
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Acute Coronary Syndrome V: Nursing Management

253
Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...

Exercise Stress Test01:26

Exercise Stress Test

1.1K
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Angina V: Nursing Management01:20

Angina V: Nursing Management

278
Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...

Area of Science:

  • Cardiology
  • Nursing Research
  • Health Services Research

Background:

  • Cardiac risk assessment is crucial in emergency settings.
  • The Triage Rule-Out Using High-Sensitivity Troponin (TRUST) algorithm aids in evaluating patients with chest pain.
  • Validating clinical tools for diverse healthcare contexts is essential.

Purpose of the Study:

  • To demonstrate the validity of the TRUST algorithm for cardiac risk assessment by nurses in Brazil.
  • To ensure the cross-cultural adaptation of the TRUST algorithm meets Brazilian healthcare standards.
  • To evaluate the comprehensibility and relevance of the adapted TRUST algorithm for nursing practice.

Main Methods:

  • A six-stage cross-cultural adaptation process was employed, including translation, back-translation, and expert committee validation.
  • Content validity was assessed using the Content Validity Index (CVI), and reliability using Cronbach's Alpha.
  • A pre-test involving 31 nurses evaluated the algorithm's clarity and relevance in the Brazilian context.

Main Results:

  • The adapted TRUST algorithm demonstrated high content validity (CVI > 0.90) and good reliability (Cronbach's Alpha = 0.80).
  • Nurses in the pre-test found the algorithm clear, relevant, and comprehensible.
  • Technical and cultural adjustments were successfully integrated into the algorithm.

Conclusions:

  • The cross-cultural adaptation of the TRUST algorithm is valid and equivalent to the original version.
  • The adapted algorithm is suitable for use by emergency nurses in Brazil for cardiac risk assessment.
  • This validated tool can enhance the accuracy and efficiency of cardiac risk evaluation in Brazilian emergency departments.
