Your calcium score identifies whether you have possible cholesterol plaques within your coronary arteries, since plaques typically contain calcium deposits within them. With a zero calcium score, the likelihood of having a plaque within your arteries is almost nil, and your risk for having a heart attack in the near future is also very low, so congratulations on that achievement. However, a zero calcium score does not tell me your risk for having plaques in other locations, like in the vessels to your kidneys or your brain, so your question on whether you should take a statin cannot be answered without additional information.
When we look at your numbers, we take into consideration the total cholesterol, triglycerides, HDL, and LDL numbers to further elucidate your future risk for atherosclerotic disease in any blood vessel anywhere in your body. Other factors such as age, diabetes, family history, body mass index, other comorbid conditions, and smoking also play into risk stratification and are used to determine whether the benefits of taking the medication outweigh the risks.
So, after a long-winded, but still incomplete, dissertation on whether you should or should not be placed on a statin, more information will be required before a recommendation can be made. A single, non-elevated value should not be used solely for the determination. That said, recent but long-term studies have shown that statins, in general, are beneficial to decrease the risk for future adverse vascular events, even in patients with zero coronary calcium scores. The studies are quite convincing that I have placed myself on a statin even though I too have a zero calcium score and no other medical conditions that increase my risk for heart attack.
