Is it true that by taking flu shots you can reduce the risk of heart attack?

Not necessarily: You can prevent the flu, but a heart attack is due to underlying coronary artery disease. If you have significant coronary disease and acquire the flu it could possibly lead to a heart attack, but at your age it would be highly unlikely. Preventing the flu is important no matter what age you are, so get a flu vaccine every year to reduce your risk.

Doubt it: Does reduce risk of flu, which has a significant mortality usually from lung complications or sepsis. A few may die of heart secondary to lungs if they had pre-existing heart disease.
