Insights

Left ventricular diastolic dysfunction (LVDD) affects over 30% of systemic sclerosis (SSc) patients. Key predictors include older age, pulmonary arterial hypertension, anti-RNP antibodies, elevated white blood cell count, and metabolic factors.

Area of Science:

  • Cardiology
  • Rheumatology
  • Internal Medicine

Background:

  • Left ventricular diastolic dysfunction (LVDD) is a significant cardiac complication in systemic sclerosis (SSc).
  • LVDD is associated with increased mortality in SSc patients.
  • Risk factors for SSc-LVDD remain poorly understood.

Purpose of the Study:

  • To determine the prevalence of LVDD in a cohort of SSc patients.
  • To identify potential predictors and risk factors associated with LVDD in SSc.

Main Methods:

  • A prospective, multi-center cohort study involving 784 SSc patients.
  • Echocardiography was used for LVDD assessment.
  • Univariate and multivariate regression analyses were performed to identify independent risk factors.

Main Results:

  • The prevalence of LVDD was 31.4% (246/784) among SSc patients.
  • Independent predictors of LVDD included older age at onset, pulmonary arterial hypertension (PAH), positive anti-RNP antibody, increased white blood cell (WBC) count, elevated uric acid, and triglyceride levels.
  • No significant differences in gender, BMI, or disease duration were observed between groups.

Conclusions:

  • LVDD is a prevalent complication in the SSc population.
  • Advanced age at onset, PAH, anti-RNP antibody positivity, elevated WBC count, and adverse metabolic status are independent risk factors for SSc-related LVDD.

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

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...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
