Disfunção aórtica é uma Síndrome?

The Syndrome of Degenerative Calcific Aortic Stenosis: Prevalence of Multiple Pathophysiologic Disorders in Association with Valvular Stenosis and Their Implications

Results: A total of 164 patients had severe AS and 51 had moderate AS. In patients with severe AS, the prevalence of increased vascular load was 42%; LV systolic and diastolic dysfunction was present in 27% and 42%; other valve diseases in 23%; and comorbid disorders in 82%. In the moderate AS group, abnormal vascular load was found in 52%; LV systolic and diastolic dysfunction was prevalent in 26% and 31%; other valve diseases in 17%; and comorbid disorders in 78% patients. More than half the patients in both groups had symptoms. In both severe and moderate AS groups, the prevalence of increased vascular load and systolic dysfunction was higher in the symptomatic group.

Conclusion: Considerable number of patients with DCAS have abnormal vascular load, abnormal LV function, and significant coexisting disorders. These could influence the total pathophysiologic burden on the heart and symptom expression. Thus, DCAS should not be considered just as valvular stenosis, but a syndrome of DCAS because of the diagnostic, prognostic, and therapeutic implications of various factors associated with it.

A idéia levantada é muito boa. A doença não vem sozinha. Os outros achados são causas e consequências da doença aórtica valvar.
