<s>[INST] Who gets heart failure? [/INST] Heart failure can develop at any age but clearly becomes more common with increasing age. Around 1% of people under 65 years of age have heart failure, but 7% of 75-84-year-olds have heart failure and this increases to 15% in people older than 85. It is the most common cause of hospitalisation in patients over 65 years of age. Source: HEART FAILURE MATTERS . Link: https://www.heartfailurematters.org/faq/frequently-asked-questions/.
