Abstract

The objectives of this study were to determine the natural history of abnormalities in left ventricular size and function in patients with systemic lupus erythematosus and to determine whether changes in ventricular function can be attributed to a primary lupus cardiomyopathy. The design was a prospective 5-year follow-up study in a university hospital. There were 28 patients with systemic lupus erythematosis who were enrolled in an echocardiographic study from 1985 to 1986 and who were available for follow-up echocardiographic examinations. Patients were prospectively subgrouped according to the presence or absence of systemic hypertension. Twenty healthy volunteers participated as normal control subjects. Measurements of left ventricular mass index, mean wall thickness, volumes, and ejection fraction and Doppler indices of mitral inflow were performed on all patients and control subjects. Increases in left ventricular mass index, mean wall thickness, and end-systolic volume and decreases in ejection fraction were seen in the patients with lupus when compared with control subjects (p < or = 0.05) and were related to the presence of hypertension and coronary artery disease. In the group of patients without hypertension, no significant differences in left ventricular mass index, volumes, or ejection fraction were detected when compared with the control group. The normotensive patients did demonstrate mild abnormalities of mitral inflow that did not worsen during the follow-up period. It was concluded that abnormalities of systolic and diastolic left ventricular function are common in patients with lupus, are progressive over time, and are related to the coexistence of hypertension and coronary artery disease.(ABSTRACT TRUNCATED AT 250 WORDS).
