Systemic sclerosis and acute heart failure in prosthetic heart valve patients: A retrospective analysis.

Background: Acute heart failure in patients with prosthetic heart valves is a complex problem with clinical and therapeutic challenges. Systemic sclerosis is a chronic autoimmune disease frequently associated with valvular abnormalities. The association between systemic sclerosis and acute heart failure in patients with prosthetic heart valves remains understudied.

Methods: Prosthetic valve patients were extracted from the National Inpatient Sample Database. Baseline patient demographics, comorbidities, and known acute heart failure risk factors were collected from the database using International Classification of Diseases, 10th Revision codes. Patients were subsequently stratified by the diagnosis of systemic sclerosis. The primary outcome was acute heart failure. while secondary outcome included pulmonary outcomes. Univariate and multivariate logistic regression analyses were performed. 1:1 matching was performed to verify our findings.

Results: Among 188,615 patients, 235 patients had systemic sclerosis. Systemic sclerosis patients had higher rates of acute heart failure relative to non-systemic sclerosis patients (28.5% vs 22.6%). On multivariate analysis, systemic sclerosis was associated with increased acute heart failure (adjusted OR: 1.38 (1.02-1.85), p = 0.036). After matching, systemic sclerosis was still associated with an increased incidence of acute heart failure (OR: 1.94 (1.25-3.03), p = 0.003). On subgroup analysis, patients with CREST syndrome did not show significantly increased acute heart failure (OR: 1.44 (0.84-2.47), p = 0.184). Patients with systemic sclerosis also showed a significantly higher rate of acute respiratory failure compared to non-systemic sclerosis patients (20.9% vs 13.7%, p = 0.001).

Conclusion: Systemic sclerosis may increase the risk for acute heart failure in patients with prosthetic valves. Closer monitoring for heart failure symptoms should be considered in systemic sclerosis patients with prosthetic valves.
