Background: Advances have been made in the medical management of congestive heart failure. However, there is concern that these changes may not be transmitted to the heart failure population in the community. Other impediments to improved prognosis, such as failure to apply non-pharmacological strategies and poor patient comprehension may also be prevalent in the community. Aims: The purpose of this study was to assess physician practice and patient knowledge in a heart failure population admitted to a University Hospital in Ireland. Methods: Patients admitted with a primary diagnosis of heart failure were studied. Estimation of ejection fraction was used to subdivide the population into heart failure with impaired and normal systolic function. Patients' course in hospital was noted with reference to management by cardiology or internal medicine, use of angiotensin-converting enzyme inhibition therapy and digoxin and application of dietary and rehabilitative services. Patient knowledge was assessed by questionnaire. Results: Eighty patients were included in this study. Two-thirds of the population had impaired systolic function. The majority of patients were managed by internal medicine physicians, and this population was older and more likely to have normal systolic function. Prescription of converting enzyme inhibitor therapy was more Ž . frequently used in cardiology-managed patients 96 vs. 70%, P -0.05 . Neither group applied dietary or rehabilitative advice to a significant level. Patient comprehension was poor, especially with regard to understanding of medicine and the value of weight measurement. Conclusion: The above data demonstrate a lack of use of rehabilitative and dietary services and poor patient knowledge. These deficiencies may play a role in determining outlook and may impede the expected improvement in prognosis that has been witnessed in large randomised studies. ᮊ
Many patients admitted to hospital with heart failure have preserved left ventricular (LV) systolic function. The incidence of isolated diastolic dysfunction as a cause of such admission remains unclear. We aimed to examine diastolic function in unselected admissions from the community with heart failure using the European Study Group on Diastolic Heart Failure (ESGDHF) Doppler-echocardiographic indices of diastolic dysfunction. Primary heart failure was confirmed in 210 of 309 sequential admissions with suspected heart failure. Doppler echocardiography was used to assess left ventricular ejection fraction, wall thickness and parameters of diastolic function including E:A ratio, E-wave deceleration time and isovolumic relaxation time. Of 210 patients studied (118 female), ejection fraction was -45% in 111, leaving a population of 99 with preserved systolic function. We excluded those with significant valvular disease, leaving 56 patients (mean ages77 years) with an ejection fraction )45% and no other relevant abnormality. Twenty were in atrial fibrillation. E-wave deceleration time was )280 ms in 42%. E:A was reversed in 30 of 36 patients in sinus rhythm, but only seven met the ESGDHF criterion of E:A-0.5. Isovolumic relaxation time was )105 ms in 38%. Wall thickness was increased in 75% of cases. The ESGDHF Doppler-echocardiographic criteria for diastolic heart failure were fulfilled in 43%. In clinically confirmed heart failure, 27% of patients had preserved systolic function and no significant valvular disease. Only 43% of this group had confirmed diastolic heart failure by these ESGDHF criteria. The pathophysiological basis of the syndrome in the remaining 57% remains unclear.
