Cardiopulmonary Exercise Testing: Deciphering Cardiovascular Complications in Systemic Sclerosis.

Area of Science:

• Cardiology
• Rheumatology
• Pulmonology

Background:

• Systemic sclerosis (SSc) frequently causes cardiac issues like impaired right ventricular function and heart failure.
• Pulmonary arterial hypertension (PAH), interstitial lung disease, and myocardial involvement are common in SSc, leading to exercise intolerance.
• Current guidelines lack specific recommendations for CPET in SSc patient evaluation.

Purpose of the Study:

• To review the development, evidence, and application of cardiopulmonary exercise testing (CPET) for assessing cardiac involvement in systemic sclerosis (SSc).
• To emphasize the utility of CPET in diagnosing exercise intolerance and identifying SSc patients at risk for PAH.

Main Methods:

• Literature review focusing on the role of CPET in systemic sclerosis.
• Analysis of evidence supporting CPET for diagnosing exercise intolerance and predicting outcomes in SSc.
• Examination of CPET's application in identifying patients with SSc at risk for pulmonary arterial hypertension.

Main Results:

• CPET is a valuable tool for diagnosing exercise intolerance in SSc patients and understanding its causes.
• CPET can identify SSc patients with a higher risk of developing pulmonary arterial hypertension.
• The review consolidates evidence for CPET's efficacy in SSc cardiac assessment.

Conclusions:

• Cardiopulmonary exercise testing (CPET) is crucial for managing cardiac involvement in systemic sclerosis (SSc).
• Integrating CPET into SSc management guidelines can improve patient outcomes and risk stratification.
• Further research and guideline incorporation are needed to fully leverage CPET for SSc patients.
