[Electrocardiographic changes and QT interval modifications in patients with Early Arthritis]
Summary
QT interval modifications were not observed in patients with early arthritis (EA), and these changes were not associated with disease activity (DA). This study suggests that QT interval is not a reliable marker for cardiovascular risk in early arthritis patients.
Area of Science:
- Cardiology
- Rheumatology
- Clinical Electrophysiology
Background:
- QT interval modifications are noted in rheumatoid arthritis (RA) and may indicate cardiovascular risk.
- Early arthritis (EA) is a distinct phase of inflammatory joint disease.
Purpose of the Study:
- To investigate QT interval changes in patients with early arthritis (EA).
- To determine the association between QT interval modifications and disease activity (DA) in EA patients.
Main Methods:
- A case-control study involving 31 EA patients and 31 matched controls.
- Electrocardiograms (ECGs) were used to measure QT and corrected QT (QTC) intervals.
- Disease Activity Score (DAS 28) was utilized to assess disease activity levels.
Main Results:
- No significant differences in QT or QTC intervals were found between EA patients and controls.
- QT and QTC intervals did not correlate with low or moderate/high disease activity levels in EA patients.
- The study included 83.9% females with a mean age of 41.9 years.
Conclusions:
- QT interval is not significantly altered in early arthritis (EA).
- No relationship exists between QT interval modifications and disease activity (DA) in EA.
- QT interval is unlikely to be a useful biomarker for cardiovascular risk in early arthritis.

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.

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...

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...

01:23Rheumatic Heart Disease I: Introduction
763
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 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 (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...
