it's hard to say, because she and your cardiologist may honestly believe you will benefit from Crestor or the doctor(s) may have stock invested in Crestor.
I'm retired after 26 years as a healthcare professional (pharmacy). If your doctor understands you will not be compliant, she will either prescribe zocor or get that non-formulary drug approval from your insurance company for crestor - only the physician can do this, as they have to justify the whys and whatfors.

I think some of your concerns regarding the renals and liver may be allayed by reading this. If you currently do not have liver issues or not predisposed to myopathy, the doctors most likely believe the benefits outweigh any of the risks.
Liver EnzymesHMG-CoA reductase inhibitors, like some other lipid-lowering therapies, have been associated with biochemical abnormalities of liver function. The incidence of persistent elevations (>3 times the upper limit of normal
occurring on 2 or more consecutive occasions) in serum transaminases in fixed dose studies was 0.4, 0, 0, and 0.1% in patients who received rosuvastatin 5, 10, 20, and 40 mg, respectively. In most cases, the elevations were transient and resolved or improved on continued therapy or after a brief interruption in therapy. There were two cases of jaundice, for which a relationship to rosuvastatin therapy could not be determined, which resolved after discontinuation of therapy. There were no cases of liver failure or irreversible liver disease in these trials.
It is recommended that liver function tests be performed before and at 12 weeks following both the initiation of therapy and any elevation of dose, and periodically (e.g., semiannually) thereafter. Liver enzyme changes generally occur in the first 3 months of treatment with rosuvastatin. Patients who develop increased transaminase levels should be monitored until the abnormalities have resolved.
