Introduction Cardiac Emergencies

39
Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

49
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...

Coronary Artery Disease III: Clinical Manifestations

22
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Acute Coronary Syndrome III: Diagnostic Studies

19
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...

Acute Coronary Syndrome IV: Interprofessional Care

19
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...

Myocarditis III: Medical Management

13
Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Public Health

Background:

  • COVID-19 (Coronavirus Disease 2019) is frequently associated with cardiac complications.
  • Understanding the cardiac impact of SARS-CoV-2 infection is crucial for patient management.

Purpose of the Study:

  • To determine the prevalence of acute cardiac events in adults hospitalized with COVID-19.
  • To identify risk factors and outcomes associated with these cardiac events.

Main Methods:

  • A probability sample of 8,460 adults hospitalized with laboratory-confirmed SARS-CoV-2 infection was analyzed.
  • Data were collected from January 2021 to November 2021 through medical chart abstraction.
  • Prevalence of acute cardiac events was calculated, stratified by history of underlying cardiac disease, and associated risk factors and outcomes were examined.

Main Results:

  • 11.4% of hospitalized adults experienced an acute cardiac event.
  • Prevalence was significantly higher in those with pre-existing cardiac disease (23.4%) compared to those without (6.2%).
  • Acute ischemic heart disease and acute heart failure were the most common events; patients with events had increased risk of ICU admission and in-hospital death.

Conclusions:

  • Acute cardiac events are a significant concern during COVID-19 hospitalizations, particularly for individuals with underlying cardiac conditions.
  • These events are linked to more severe disease outcomes, including higher mortality.
  • Enhanced clinical evaluation and monitoring are recommended for high-risk patients during hospitalization for COVID-19.
