Insights

WhatsApp® telemedicine significantly increased reperfusion therapy for ST-segment elevation myocardial infarction (STEMI) patients in Brazil. This innovation also reduced in-hospital mortality rates, improving patient outcomes.

Area of Science:

  • Cardiology
  • Telemedicine
  • Public Health

Background:

  • ST-segment elevation myocardial infarction (STEMI) affects numerous patients in Brazil.
  • A significant percentage of STEMI patients do not receive timely reperfusion therapy.

Purpose of the Study:

  • To evaluate the impact of a WhatsApp®-based telemedicine network on reperfusion therapy rates.
  • To assess changes in in-hospital mortality following telemedicine implementation for STEMI patients.

Main Methods:

  • A cross-sectional study compared outcomes before and after implementing a telemedicine network using WhatsApp® for STEMI patient ECG transmission.
  • Data from 25 municipalities were analyzed, comparing 82 patients pre-implementation (2016-2018) with 196 post-implementation (2018-2020).

Main Results:

  • Reperfusion therapy rates increased significantly from 60% to 92% (RR: 1.594, p < 0.0001).
  • In-hospital mortality decreased from 13.4% to 5.6% (RR: 0.418, p = 0.028).

Conclusions:

  • WhatsApp®-based telemedicine is effective in increasing reperfusion therapy for STEMI patients.
  • The implemented telemedicine network led to a significant reduction in STEMI patient mortality.

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Acute Coronary Syndrome I: Introduction

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...

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,...

Acute Coronary Syndrome III: Diagnostic Studies

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...

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...
