Insights

Rheumatoid arthritis patients exhibit increased coronary calcification and subclinical myocardial dysfunction, indicated by higher brain natriuretic peptide (BNP) levels and electrocardiogram abnormalities, compared to controls.

Area of Science:

  • Rheumatology
  • Cardiology
  • Inflammatory Diseases

Context:

  • Rheumatoid arthritis (RA) is linked to elevated cardiovascular mortality, potentially due to systemic inflammation.
  • Subclinical cardiovascular disease assessment is crucial in RA management.

Purpose:

  • To investigate coronary calcification via computed tomography (CT) and subclinical myocardial dysfunction using brain natriuretic peptide (BNP) levels and electrocardiogram (ECG) in RA patients.
  • To explore the relationship between these cardiovascular markers and RA disease characteristics.

Summary:

  • RA patients (n=73) showed a trend towards higher coronary artery calcium scores compared to osteoarthritis controls (n=73).
  • RA patients exhibited significantly higher BNP levels, prolonged corrected QT interval, increased large QT frequency, and a higher prevalence of silent myocardial infarction.
  • Coronary calcification in RA was associated with disease duration.

Impact:

  • RA patients demonstrate a greater frequency of coronary calcification and biochemical/ECG indicators of subclinical myocardial dysfunction than the general population.
  • These findings highlight the heightened cardiovascular risk in RA patients, even in the absence of clinical cardiovascular events.
  • Early detection and management of subclinical cardiovascular disease are critical for improving outcomes in rheumatoid arthritis.

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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
