Objective-To determine the referral rates to hospital and level of inv
estigation of patients with heart failure, and, to assess whether they
are receiving optimum management. Design-A retrospective survey. Sett
ing-Nottingham Health District. Patients-505 patients receiving loop d
iuretic treatment prescribed by their general practitioner. Main outco
me measures-Referral to hospital as an inpatient or outpatient for ass
essment of assumed cardiac failure; investigations-electrocardiography
, chest radiography, and echocardiography; treatment with angiotensin
converting enzyme inhibitors. Results-Only 56% of patients prescribed
loop diuretics fulfilled the diagnostic criteria for heart failure. Of
these, 74% had been referred to hospital, of whom 80% had had an elec
trocardiograph, 75% a chest radiograph, but only 31% an echocardiogram
. Only 17% of patients with heart failure were being treated with angi
otensin converting enzyme inhibitors in conjunction with loop diuretic
s. Conclusions-Patients with heart failure in the Nottingham Health Di
strict are not being adequately investigated or receiving the optimum
treatment.
