Insights

Cardiac involvement is common in collagen diseases, affecting over a third of patients. Rhythm disturbances and cardiomyopathies are frequent, impacting disease prognosis and requiring central diagnostic focus.

Area of Science:

  • Cardiology
  • Rheumatology
  • Internal Medicine

Background:

  • Collagen diseases, a group of autoimmune disorders, can affect multiple organ systems.
  • Cardiac involvement is a significant concern in patients with collagen diseases, influencing morbidity and mortality.

Purpose of the Study:

  • To determine the prevalence and types of cardiac disorders in patients with collagen diseases.
  • To analyze the impact of cardiac involvement on the prognosis of collagen diseases.

Main Methods:

  • Retrospective analysis of 917 patients diagnosed with collagen diseases between 1985 and 1987.
  • Cardiac disorders were diagnosed using clinical evaluation, ECG, radiology, and echocardiography.

Main Results:

  • Cardiac involvement was diagnosed in 38.2% of patients; exceeding 50% in systemic lupus erythematosus, polyarteritis nodosa, and progressive systemic sclerosis.
  • Rhythm and conduction disturbances were most frequent (12.2%), followed by cardiomyopathies/myocarditis (7.4%).
  • Myocardial ischemia due to coronary vasculitis was identified as a key pathogenic mechanism.

Conclusions:

  • Cardiac involvement is a frequent and severe complication of collagen diseases.
  • It presents significant diagnostic, therapeutic, and prognostic challenges, often becoming a central issue in patient management.

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

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...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Coronary Artery Disease III: Clinical Manifestations

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

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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
