Cardiac involvement in the catastrophic antiphospholipid syndrome (CAPS): Lessons from the "CAPS registry "

# metadata.dc.description.abstract[].value
Objective: To analyze the demographic, clinical, and laboratory characteristics of catastrophic antiphospholipid syndrome (CAPS) patients with cardiac involvement, and to identify the factors associated with this cardiac involvement. Material and methods: Based on the analysis of the "CAPS Registry", the demographic, clinical, and serological characteristics of patients with cardiac involvement were analyzed. Cardiac involvement was defined as heart failure, valvular disease, acute myocardial infarction, pericardial effusion, pulmonary arterial hypertension, systolic dysfunction, intracardiac thrombosis, and microvascular disease. Univariate and multivariate analysis was used for multiple comparisons. Results: 749 patients (293 [39 %] women and mean age 38.1 +/- 16.2 years) accounting for 778 CAPS events were included, of them 404 (52 %) had cardiac involvement. The main cardiac manifestations were heart failure in 185/377 (55 %), valve disease in 116/377 (31 %), and acute myocardial infarction in 104/378 (28 %). Of 58 patients with autopsy/biopsy, 48 (83 %) had cardiac thrombotic microangiopathy, Stroke (29% vs. 21 %, p = 0.012), transient cerebral vascular accident (2% vs. 1 %, p = 0.005), pulmonary infarction (26% vs. 3 %, p = 0.017), renal infarction (46% vs. 35 %, p = 0.006), acute kidney injury (70% vs. 53 %, p < 0.001), and livedo reticularis (24% vs. 17 %, p = 0.016) were significantly more frequent during CAPS events with versus without heart involvement. Multivariate analysis identified acute kidney injury (OR 1.068, IC 95 % 1.8-4.8, p < 0.001) as the only clinical characteristics that were, independently, associated with cardiac involvement in CAPS events. Cardiac involvement was not related to higher mortality. Conclusions: Cardiac involvement is frequent in CAPS, with association with kidney involvement, and it is not related to higher mortality. The presence of cardiac microthrombosis was demonstrated in most biopsies/autopsies performed.
