The study also found that the number of patients who died due to heart failure in the first year of treatment fell by 80%.
The most common cause of death for heart failure is congestive heart failure, but patients with other cardiac problems may also have a harder time recovering.
This means that people who do recover can potentially benefit from treatment.
“The biggest impact of this is to improve the survival of those patients who are going to need treatment in the longer term,” says Dr Zeng Zhao, a cardiologist at Johns Hopkins University School of Medicine.
“This can have a dramatic impact on the outcome of heart failure.”
But how much longer can patients stay on the treatment?
It depends on a number of factors, including the age and type of heart disease.
People who are younger and healthier may not need treatment for longer, but older patients may need more treatment, and those with high blood pressure can benefit from more intensive treatment, says Dr Zhao.
“People who are older are more likely to have an increased risk of having a subsequent heart attack or death,” he says.
“So, the longer you are on treatment, the higher the risk of a subsequent attack and death.”
The study used data from the NHS Longitudinal Follow-Up Study, which followed more than 13,000 people from 1996 to 2012.
The NHS LFS uses a blood pressure questionnaire to collect data on patients’ medical history, blood pressure and cardiovascular disease.
The study was supported by the National Institute for Health Research (NICE), which provides grants to universities to carry out research into the health effects of treatments.
