We would expect your LDL would likely be lowered by approx 25-35% with this dose of lipitor (though is variable between patients), so the reduction you describe is likely a combination of both interventions. While aggressive diet modification as your are doing will go a long way to prevent further events and progression of coronary artery disease, I would not recommend stopping the lipitor. We have good data that statin therapy improves outcomes in patients with CAD with improvement seen at even lower dose of cholesterol then you have. We also know that statins seem to have beneficial effects independent of cholesterol reduction including anti-inflammatory effect and possible improvement of the health of the inner lining of the blood vessels.
let me add: I'm 84, one stent RCA, May 2010
I stopped Crestor for 33 days. my lipids were:
TC 139
HDL 35
TRG 126
LDL/HDL 2.3
GLU 88
Now they are:
TC 211
HDL 29
TRG 164
LDL/HDL 5
GLU 96
I did not relax my strict Mediterrean diet nor hard daily exercise. Now I take the side of statins in the on-going controversy on whether they do any good or not.
(I dropped Crestor to see if i twas the cause of my two-year bout of night sweats. I still have them.)
I've read several reviews from folks who have had substantial cholesterol reduction via the plant based nutrition, so my best guess is you should be able to go on "autopilot" with just the diet alone without the statin and get TC<150, but be sure to mention to your doctor what you are doing with the diet. This plant based diet, if follwed rigorously, will acutally accomplish the same thing as the Lipitor in that it heals the arteries and prevents inflammation from developing without the side effects of medication.
I am also on a plant based diet, and although I cannot comment on my cholesterol reduction as I did not have high cholesterol prior to the diet, I can attest to it's BP lowering effects. Here are my results before and after a year later:
October 2011
Blood Pressure 159/110 (Before medication)
Total cholesterol 104
HDL 47
LDL 37
Triglycerides 104
Glucose 130
October 2012
Blood Pressure 118/63 (No medication)
Total cholesterol 94
HDL 47
LDL 34
Triglycerides 64
Glucose 96
I discontinued BP meds 2 months after starting as BP plummeted quickly.
We generally recommend you stay on it indefinitely as long as you are tolerating the medication without issues. It is important to say that it is important for you to maintain the diet changes you discussed above. It sounds like you are very motivated to make these changes. Congratulations on what you have done so far and good luck in the future.
Thank you. next Sept 13 (2013) will be a year after my MI. Given what you say about the other benefits of taking lipitor, are you implying that I should stay on liptior indefinitely? Or is there an optimum period of time? again, assuming I can keep cholesterol under control by diet alone.
