[Characteristics and clinical course of degenerative aortic stenosis in the elderly].
Degenerative aortic stenosis represents the most common form of aortic stenosis. The aim of this study was to evaluate the relationship between symptoms, valvular disease severity and prognosis. We studied the evolution of valvular aortic stenosis in 65 patients (39 males and 26 females, mean age 77.78 +/- 6.2 years) for a period of 7 years. All patients were submitted to accurate anamnestic examination, ECG, color Doppler echocardiography. Sixteen patients (26%) underwent cardiac catheterization. Associated diseases were: hypertension (45%), diabetes (40%), dyslipidemia (29%), chronic obstructive lung disease (6%). In 64% patients, the diagnosis of aortic stenosis was made after symptoms onset, and in 36% was occasional. Mean age at symptoms onset was 70 +/- 17 years: dispnoea was present in 81%, chest pain in 32%, and syncope in 8%. At the beginning of the follow-up, echocardiography showed, aortic stenosis to be mild in 21.73%, moderate in 60.8% and severe in 17.4%. At the end of the follow-up, mild stenosis was present in 9.5%, moderate in 38.7%, and severe in 51.8%. At entry, 56.6% had pure aortic stenosis, 34.78% had steno-insufficiency and 8.7 had an associated mitral valve insufficiency. At the end of the follow-up pure aortic stenosis was present in 17%, steno-insufficiency in 40%, and associated mitral valve insufficiency in 4.3%. Surgery was performed in 21% of the patients (77% valve replacement and 23% valve replacement and aortocoronary bypass). The mortality, at the end of the follow-up, was 31%. Causes of death were: heart failure (61%), arrhythmias (23%), and surgical complications (16%).(ABSTRACT TRUNCATED AT 250 WORDS)
