Abstract

OBJECTIVES: To characterise the clinical features of patients with suspected heart failure but preserved left ventricular systolic function to determine if they have other potential causes for their symptoms rather than being diagnosed with "diastolic heart failure." DESIGN: Prospective descriptive study. SETTING: Outpatient based direct access echocardiography service. PARTICIPANTS: 159 consecutive patients with suspected heart failure referred by general practitioners. MAIN OUTCOME MEASURES: Symptoms (including shortness of breath, ankle oedema, and paroxysmal nocturnal dyspnoea) and history of coronary heart disease and chronic pulmonary disease. Transthoracic echocardiography, body mass index, pulmonary function tests, and electrocardiography. RESULTS: 109 of 159 participants had suspected heart failure in the absence of left ventricular systolic dysfunction, valvular heart disease, or atrial fibrillation. Of these 109, 40 were either obese or very obese, 54 had a reduction in forced expiratory volume in 1 second to </=70%, and 97 had a peak expiratory flow rate </=70% of normal. Thirty one patients had a history of angina, 12 had had a myocardial infarction, and seven had undergone a coronary artery bypass graft. Only seven patients lacked a recognised explanation for their symptoms. CONCLUSIONS: For most patients with a diagnosis of heart failure but preserved left ventricular systolic function there is an alternative explanation for their symptoms-for example, obesity, lung disease, and myocardial ischaemia-and the diagnosis of diastolic heart failure is rarely needed. These alternative diagnoses should be rigorously sought and managed accordingly.

  • Misdiagnosis of heart failure is common and may be more common in obese subjects because of the frequent occurrences of edema and dyspnea.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
