Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations01:19

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

119
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Acute Coronary Syndrome IV: Interprofessional Care

86
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 V: Nursing Management

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 I: Introduction01:30

Acute Coronary Syndrome I: Introduction

255
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 III: Diagnostic Studies

78
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...

Area of Science:

  • Infectious Diseases
  • Pulmonology
  • Public Health

Background:

  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the COVID-19 pandemic, leading to global health challenges.
  • COVID-19 is increasingly recognized as a multi-organ disease with diverse clinical presentations.
  • Persistent symptoms and long-term complications after acute COVID-19 are increasingly reported, termed post-acute COVID-19.

Purpose of the Study:

  • To comprehensively review the current literature on post-acute COVID-19.
  • To explore the pathophysiology and organ-specific sequelae of post-acute COVID-19.
  • To discuss multidisciplinary care considerations and propose a management framework for COVID-19 survivors.

Main Methods:

  • Comprehensive literature review of post-acute COVID-19.
  • Analysis of pathophysiology and organ-specific complications.
  • Discussion of clinical management strategies.

Main Results:

  • Post-acute COVID-19 is characterized by persistent symptoms and/or delayed complications beyond 4 weeks.
  • The syndrome affects multiple organs, similar to other severe coronavirus epidemics.
  • Patient advocacy groups have been instrumental in recognizing post-acute COVID-19.

Conclusions:

  • Effective management of COVID-19 survivors requires understanding post-acute sequelae.
  • A multidisciplinary approach is essential for coordinated care.
  • Identifying high-risk individuals and implementing dedicated management frameworks are priorities.
