EF 40-50% + AF + valve disease†
|
AF (EF >50%)
|
Valve disease† (EF >50%)
|
AF + valve disease† (EF >50%)
|
Total definite HF
|
EF 40-50% alone
|
Total HF (definite + probable)

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Previous myocardial infarction (n=244) | 28 (11.5) | 0 | 1 (0.4) | 2 (0.8) | 2 (0.8) | 1 (0.4) | 0 | 5 (2.0) | 0 | 0 | 39 (16) | 22 (9.0) | 67 (27.5) |

AF=atrial fibrillation; EF=ejection fraction; HF=heart failure.
In addition, six patients with previous myocardial with EF <40% had no symptoms of dyspnoea at time of assessment but were taking diuretics or angiotensin converting enzyme inhibitors; this applied also to two of hypertension group, two of angina group, and none of diabetes group.
Of the four patients with previous myocardial infarction and valve disease, one had mitral stenosis (MS) and three had mitral regurgitation (MR). Of the four with hypertension and valve disease, three had MR and one had aortic stenosis (AS). Of the nine with angina and valve disease, seven had MR and two had AS. Of the five with diabetes and valve disease, three had MR and two had AS.
