Hello. i know the prevalence of heart failure in 50 year olds is 1 out of 100 / 1 % but what is the prevalence in 20 year olds? it tells me 0.3%3/1000

More than age: Different cultural and genetic populations will vary perhaps. More than age matters and when it is so rare an event, one could argue that it's not meaningful - but here's more info. Here's some USA info: http://www.heart.org/idc/groups/heart-public/@wcm/@sop/@smd/documents/downloadable/ucm_319577.pdf Best!

Not an issue: Prevalence is important only for public health researchers and officials. For the individual, the concern should be do you have risk factors and symptoms of CHF. If you havensigns and symptoms of CHF, then you should investigate the cause further. CHF is so rare at 20, it is almost always due to birth defect or rare infections of the heart. https://www.cardiosmart.org/Heart-Basics/CVD-Stats

True: Causes of heart failure include Hypertension, Diabetes 2 and cholesterol problems. These conditions are more common in 50 year olds than in 20 year olds.
