AbstractAmong 380 consecutive patients > 70 years of age, patients with a systolic heart murmur were investigated both clinically and by doppler echocardiography. The aim of the study was to compare the validity of the clinical diagnosis of valvular aortic stenosis in elderly patients with the results of doppler echocardiography. 138/380 patients (36%) had a systolic heart murmur. 130 were investigated by doppler echocardiography. 23/130 patients with systolic murmur (18%) had moderate or severe aortic stenosis. Clinically, patients with moderate or severe aortic stenosis had a pulsus parvus et tardus of the carotid artery more often than patients with only slight or no evidence of aortic stenosis (61% vs 16%; p < 0.0001). In patients with moderate or severe aortic stenosis, the murmur radiated more often to the carotid vessels (65% vs 19%; p < 0.0001). Systolic blood pressures and pressure amplitudes were lower in patients with moderate or severe aortic stenosis (132 vs 141 mm Hg; p < 0.01; 61 vs 68 mm Hg; p < 0.001). Electrocardiography showed left ventricular hypertrophy or bundle branch block more often in patients with moderate or severe aortic stenosis (57% vs 15%; p < 0.01). We conclude that moderate or severe aortic stenosis is a frequent finding in elderly patients. Diagnosis by clinical examination may be difficult. For this reason, doppler echocardiography should be performed, especially when therapeutic consequences are to be expected from the diagnosis, such as aortic valve replacement or vasodilator treatment in the case of congestive heart failure.
