Abstract 15221: The Prevalence of Valvular Heart Disease in Community Patients With Suspected Heart Failure
Background: Valvular heart disease is recognized as an important cause of morbidity and mortality. Early diagnosis is therefore essential as there are serious consequences for undiagnosed patients. We have developed a large scale, prospective community echocardiography service for the evaluation of patients with suspected heart failure. The aim of this study was to evaluate the proportion of these patients with significant valvular heart disease.
Methods: We prospectively evaluated 79,043 patients, between 2001 and 2011, who were referred to a community open access echocardiography service for suspected heart failure. All patients underwent a standard transthoracic echocardiogram according to British Society of Echocardiography guidelines. 2371 (3%) had mild impairment of left ventricular (LV) systolic function, 3161 (4%) had moderate impairment of LV systolic function and 3972 (5%) had severe impairment of LV systolic function. 18, 970 (24%) patients had moderate to severe LV diastolic dysfunction.
Results: Of the total number, 29,682 patients (37.5%) were diagnosed with mild valve disease, 8983 patients (11.3%) had moderate valve disease and 2134 (2.7%) had severe valve disease (see Table with prevalence of heart valve disease in % given of a total number). There was no difference in the frequency of the valve disease between men and women.
Conclusion: In the community setting, a significant proportion of patients with suspected heart failure have important valvular heart disease. These patients are at high risk of future cardiac events and will require onward referral for further evaluation.
