Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
Myocarditis I: Introduction01:21

Myocarditis I: Introduction

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Overview
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
Pericarditis I: Introduction01:22

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Area of Science:

  • Cardiology
  • Immunology
  • Thrombosis

Background:

  • Atrial fibrillation (AF) increases stroke and embolism risk.
  • Inflammation is increasingly linked to AF initiation, perpetuation, and thrombosis.
  • Elevated inflammatory markers are observed in AF patients.

Purpose of the Study:

  • To review the current understanding of the association between inflammation and AF.
  • To discuss the impact of inflammatory markers on AF clinical presentation.
  • To examine the influence of inflammation on AF patient outcomes.

Main Methods:

  • Literature review of studies on inflammation and atrial fibrillation.
  • Analysis of associations between specific inflammatory markers and AF.
  • Examination of proposed pathophysiological mechanisms.

Main Results:

  • Several inflammatory markers (CRP, TNF-α, IL-2, IL-6, IL-8) are linked to AF.
  • Inflammation contributes to AF-related prothrombotic state via endothelial activation, monocyte tissue factor production, platelet activation, and fibrinogen expression.
  • Inflammatory markers correlate with AF clinical presentation and patient outcomes.

Conclusions:

  • Inflammation is a significant factor in atrial fibrillation pathogenesis and prognosis.
  • Understanding the inflammatory pathways in AF can inform clinical management and risk stratification.
  • Targeting inflammatory processes may offer novel therapeutic strategies for AF.
