40 free Cardiovascular Disease trivia questions with answers — science & nature quiz, new questions added Oct 2026.
Cardiovascular diseases kill more people worldwide than anything else, yet up to 90% of cases may be preventable. That gap between how common they are and how avoidable they are is what makes the subject worth knowing, whether for an exam or for your own health. This quiz covers the conditions themselves, from heart attacks and strokes to blood clots, faulty rhythms and defects present from birth. It also covers the warning signs, the everyday habits that raise or lower the risk, and the surprising places some heart medicines came from. A few questions follow the famous patients and stubborn researchers who shaped what doctors know today. It suits nursing and biology students revising the basics, quiz hosts building a health round, and anyone who wants to follow what their doctor is saying. Every answer comes with a short explanation, so a wrong guess still teaches something.
