Summary
Ankylosing spondylitis patients show increased diastolic left ventricular dysfunction. This condition, a precursor to heart failure, is more prevalent in AS patients than in controls, indicating a higher cardiovascular risk.
Area of Science:
- Cardiology
- Rheumatology
- Echocardiography
Background:
- Ankylosing spondylitis (AS) is linked to higher mortality, primarily from cardiovascular disease.
- Diastolic left ventricular (LV) dysfunction precedes heart failure and contributes to morbidity and mortality.
Purpose of the Study:
- To systematically review and determine the prevalence of diastolic LV dysfunction in patients diagnosed with AS.
Main Methods:
- Conducted a systematic literature search for echocardiographic studies on diastolic LV function in AS patients.
- Included 11 studies that met the selection criteria from an initial pool of 166.
Main Results:
- AS patients exhibited impaired diastolic LV function, evidenced by a worse E/A ratio, prolonged deceleration time, and prolonged isovolumetric relaxation time compared to controls.
- Studies combining these parameters confirmed a higher prevalence of diastolic LV dysfunction in AS patients (ranging from 9% to 45%) versus controls (0% to 18%).
Conclusions:
- Findings support an elevated risk of diastolic LV dysfunction in individuals with AS.
- Further large-scale research is necessary to quantify this risk and understand its clinical significance in AS management.

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...

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

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...

1.6K
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

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...
