We wanted to assess the prevalence and evolution of left myocardial disease, pulmonary hypertension and intracardiac thrombi in a cohort of APS patients. A total of 53 patients with APS, either primary (n = 34, 64%) or associated to lupus (n = 19, 36%) and 20 controls were included. Initial transthoracic echocardiography assessment was performed in patients at diagnosis, with echocardiography controls performed along mean follow-up of 12 years. Prevalence of myocardial disease in APS cohort was assessed taking into account primary risk factors (hemodynamically significant valvular disease, systemic hypertension, diabetes, alcoholism, myocardial infarction or myocarditis), the same as for pulmonary hypertension (severe left ventricular dysfunction or chronic lung disease). Left myocardial disease had a prevalence of 3.8% (2/53 patients), not different from controls (P = 0.12). Both patients had diastolic dysfunction grade I that maintained stability throughout echocardiographic follow-up period. Pulmonary hypertension had a prevalence of 11.3% (6/53 patients), not different from controls (P = 0.12); all cases were related to pulmonary embolism. Patients diagnosed with pulmonary hypertension in baseline maintained stable pressures throughout follow-up in the absence of new thrombosis. Intracardiac thrombi had a prevalence of 1.8% (1/53 patients), not different from controls (P = 0.4), without changes along echocardiographic follow-up. Pulmonary hypertension is the most prevalent non-valvular cardiac manifestation in APS, with an evolution associated with thromboembolic disease, while left myocardial disease and intracardiac thrombi would be rare manifestations in APS.

We followed up patients with 'primary' APS (PAPS) and APS secondary to SLE (APS plus SLE) with the objective of comparing laboratory and clinical events and of determining whether patients with PAPS would have evolution to SLE. A total of 114 patients from 3 European referral centers were included in this study. Fifty-six had APS plus SLE and 58 had PAPS. Laboratory and clinical data were collected during an average 2-year period. Patients with PAPS and patients with APS plus SLE had similar clinical and laboratory profiles, with the exceptions of autoimmune hemolytic anemia, endocardial valve disease, neutropenia, and low C4 levels, all of which occurred more frequently in patients with APS plus SLE (p values: < 0.05, < 0.005, < 0.01, and < 0.001, respectively). On follow-up, 10 thrombotic episodes occurred in 10 patients, 8 of whom were receiving anticoagulant therapy. No patient with PAPS had either anti-DNA or anti-extractable nuclear antigen antibodies, and these patients had a significantly lower prevalence of antinuclear antibodies (41%) than patients with APS plus SLE (89%). Patients with APS plus SLE and PAPS have similar clinical profiles, although heart valve disease, hemolytic anemia, low C4 levels, and neutropenia seem to be more common in patients with APS plus SLE. Patients with APS may develop further thrombotic events despite anticoagulation therapy.

Ninety SLE patients, 29 with thrombocytopenia. were evaluated. The presence of PAA was determined using the direct and indirect platelet suspension immunofluorescence test. A total of 166 PAA determinations were performed in the 90 patients upon entry into the study. Fifty-six of the 90 patients (62%) with
