Dear you asked a very good query, still there is a possibility to generate cardiovascular disease even if the treatments and checkups were done correctly. Because of your heart examinations are examined by a physician. Experts can find out if you are completely healthy or not and at least you need a steady evaluation. In our 20s we should check up twice in every 5years, in our 30s it should be thrice in 3 to 4 years, four times in our 40s, our 50s and 60s it should be every year.
