Despite increasing survival rates from first heart attacks, one in four patients remains likely to develop heart failure within four years.
The study identified a number of factors which were associated with an increased risk of developing heart failure after a first heart attack.
- Age (45% increased risk with every 10 year rise in age)
- Greater socioeconomic deprivation (27% increased risk)
- Diabetes (44% increased risk)
- Atrial fibrillation (63% increased risk)
- Peripheral arterial disease (38% increased risk)
- Chronic obstructive pulmonary disease (28% increased risk)
- ST elevation myocardial infarction at presentation (21% increased risk)
- Hypertension (16% increased risk)
During a heart attack the supply of blood to the heart is suddenly blocked, usually by a blood clot and the subsequent lack of blood to the heart can seriously damage the heart muscle.
