Abstract/OtherAbstract:
AIM/OBJECTIVE: Peripartum cardiomyopathy (PPCM) is a disorder of unknown etiology in which symptoms of heart failure occur between the last month of pregnancy and 5 months post-partum. These findings prompted us to carry out a more detailed study aimed at correlating plasma levels of C-reactive protein TNF-α and IL-6 as prognostic value for major clinical in-hospital events and 6-month follow-up in patients with PPCM.
MATERIALS AND METHODS: After ethical clearance, in the present prospective case-control study, a total of 86 subjects were enrolled [patients (n = 46) and controls (n = 40)]. After checking for the inclusion and exclusion criteria, informed consent was obtained and patients were enrolled. The details of history of pre-eclampsia and mode of delivery were obtained from the patients. The history of onset of symptoms and signs was recorded at the first presentation and at 6 months. Clinical assessment, echocardiography, and blood analysis were done at baseline and after 6 months of standard therapy. All patients received treatment with diuretics and the ACE inhibitor (ramipril), Carvedilol if not contraindicated, and inotropic support inj-Dobutamine. Inflammatory markers (C-reactive protein, TNF-α, and IL-6) were measured at baseline and at 6 months. Data were analyzed using the SAS version 9.1 statistical program.
RESULTS: The characteristics of the study population at first presentation to the cardiac clinic are similar (compared with controls): 0.91 % of the study patients were diagnosed as PPCM patients for the first time and 49 % patients presented within one month after delivery. C-reactive protein (22 vs 08 mg/dl, p < 0.05), TNF-α (9.6 vs 3.2 pg/dl, p < 001), and IL-6 (73.19 ± 34.4 vs 31.52 ± 8.83 pg/dl, p < 0.005) were significantly abnormal, and these patients showed significantly higher LV dimensions, LV EDD (61.6 ± 7.1 vs 46 ± 9 mm p < 0.004) LV ESD (53.1 ± 7 vs 32 ± 8, p < 0.005), and significantly lower echocardiographic left ventricular ejection fraction (LVEF) (25.9 ± 8.2 vs 55 ± 12 p < 0.001) and correlate well with NYHA FC and death. LVEF improved from 25.9 ± 8.2 to 42.9 + 13.6 % at 6 months (p < 0.0001). Patients who completed 6 months of standard care showed a significant reduction of heart rate, LV dimensions, and NYHA FC (p < 0.001). However, normalization of LVEF (>50 %) was only observed in 11 (35 %) patients. Seven patients died within 6 months of diagnoses and eight patients were lost to follow-up.
CONCLUSIONS: Plasma markers of inflammation were significantly elevated in PPCM patients and correlated with increased LV dimensions and lower EF at presentation. Baseline CRP, IL-6, TNF-α, and higher NYHA FC were the only predictors of mortality. These results contribute to inflammation which may contribute to the pathogenesis of PPCM and its complications and predictors of mortality.
