N2 - Introduction: The prevalence of diastolic left ventricular (LV) dysfunction in a population presenting with a suspected diagnosis of congestive heart failure (CHF) is questionable and widely variable in the current literature. To minimize the disparity, we evaluated a large echocardiographic database to investigate the prevalence of systolic and suspected diastolic LV dysfunction in those with a suspected clinical diagnosis of CHF. Methods: We retrospectively reviewed echocardiograms performed at our institution and evaluated the prevalence of abnormal LV systolic and diastolic function in those with a suspected clinical diagnosis of CHF. Diastolic dysfunction was defined as the presence of left atrial enlargement, left ventricular hypertrophy and reverse trans-mitral inflow ratio (E/A reversal). Results: Of the 636 echocardiograms with CHF as the primary diagnosis, 461 had measured LV function. Normal LV systolic function were found in 238 of the patients (48%). Isolated diastolic LV dysfunction was found in 166 patients (36%). Twelve percent of the patients with a suspected clinical diagnosis of CHF had normal LV systolic and diastolic function. Conclusion: Normal LV systolic function was seen in nearly one-half of the echocardiograms with a suspected clinical diagnosis of CHF. Suspected LV diastolic dysfunction was observed in one-third of the echocardiograms with a suspected clinical diagnosis of CHF.
