BACKGROUND: Heart failure is associated with exercise intolerance and sleep- disordered breathing; however, studies in patients with chronic constrictive pericarditis are scarce. The purpose of our study was to assess exercise capacity and sleep in patients with chronic constrictive pericarditis (CCP) undergoing a pericardiectomy.
METHODS: We studied consecutive patients scheduled for pericardiectomy due to symptomatic CCP. Were performed quality of life (Minnesota Living with Heart Failure Questionnaire-MLHFQ) and sleep questionnaires (Epworth, Pittsburgh Sleep Quality Index-PSQI), serum B-type natriuretic peptide (BNP), serum C-reactive protein, transthoracic echocardiography, cardiopulmonary exercise test and overnight polysomnography immediately before and six months after pericardiectomy.
RESULTS: Twenty-five patients (76% males, age: 45.5±13.8 years, body mass index: 24.9±3.7 kg/m2, left ventricular ejection fraction: 60±6%) with CCP (76% idiopathic, 12% tuberculosis) were studied. As compared to the preoperative period, pericardiectomy resulted in reduction in BNP (143 (83.5-209.5) vs 76 (40-117.5) pg/mL, p = 0.011), improvement in VO2 peak (18.7±5.6 vs. 25.2±6.3 mL/kg/min, p<0.001), quality of life (MLHFQ score 62 (43,5-77,5) vs. 18 (8,5-22), p<0,001) and sleep (PSQI score 7.8±4.1 vs. 4.7±3.7, p<0.001) and no significant change in sleep disordered breathing (apnea hypopnea index-AHI 15.6 (8.3-31.7) vs. 14.6 (5.75-29.9) events/h, p = 0.253).
CONCLUSION: Patients with symptomatic CCP showed reduced exercise capacity and sleep-disordered breathing. After pericardiectomy, there was improvement in exercise capacity and neutral effect on sleep-disordered breathing.
