Abstract 3908: Pericardial Disease: Uncommon or Under-diagnosed?
Introduction: Pericardial disease (PD) can be associated with significant morbidity and mortality. It is not clear how common PD is in the cardiac outpatient population.
Hypothesis: PD syndromes are underrepresented in a large tertiary referral medical center.
Objective: To determine the prevalence of PD syndromes in the cardiology outpatient clinics (COC) at the Cleveland Clinic.
Methods: Cardiology outpatients with PD were identified using ICD 9 billing codes from January 1st 2007 through December 31st 2007. PD syndromes were classified based on the 2004 European Society of Cardiology PD Guidelines.
Results: A total of 30,383 patients (51,542 total visits) seen at COC were evaluated. Of these, 306 patients (390 total visits) were identified as having PD (50.5% men, mean age 56±17 years). Prevalence of PD in our COC patient population was 1% (306/30,383). Small to large pericardial effusions comprise the majority 70% (215/306) of PD seen at the COC. Of these, 19.5% (42/215) developed cardiac tamponade. The most frequent etiologies of pericardial effusions were idiopathic in 50% and post cardiac surgery in 30%.
Conclusion: PD accounts for a small percentage (1%) of the cardiology outpatient population at Cleveland Clinic. The predominant syndromes are: pericardial effusion, recurrent, acute, and constrictive pericarditis, respectively. The large percentage of patients with pericardial effusion is driven by the high volume of cardiac surgery at a large tertiary referral medical center. Prospective studies of PD are needed to investigate patient outcomes and survival.
