According to the new study, the Influenza vaccination in patients with high blood pressure have associated with 18% reduced the risk of death during the season of flu. The vaccination is cheap, safe, and readily available. It decreases influenza infection, said the first author Daniel Modin in the university of Copenhagen from Denmark. According to the study, it means that it would also protect from fatal heart attacks, strokes, and death of other causes.
The survey by Danish public healthcare registers to identify that during nine consecutive influenza seasons (2017-16). In that 608,452 patients aged 18 to 100 years with hypertension. The researchers have followed the patients over the season and have tracked how many have died. They have recorded deaths from all the causes as cardiovascular, heart attack, stroke. They have analysed the association between receiving the vaccine before the flu season. And have also examined the risk of death during flu season.
The analysis was in control of the patient characteristics that make the impact on the likelihood of dying, such as age, comorbidities, medications. After adjusting with patient’s differences, the vaccination associated with 18% reduction in the risk of dying from all the causes — 16 % relative reduction in the risk of dying from a cardiovascular cause. And 10% from a heart attack, stroke.
According to the study, influenza vaccination improves cardiovascular outcomes in patients, along with hypertension. The researchers noted that flu and cardiovascular disease might be connected; thus, it triggers a strong immune reaction and subsequent inflammation.
