I showed a calcium score of 1588 2 months ago. 2 arteries were above the 400 level. My PCP ordered a consultation with a cardiologist and this led to an angiogram performed in February. At my follow-up visit with the cardiologist the test results showed blockages no higher than 20%. I am 70, and he adjusted my medications, especially doubling the Lipitor dosage; took me off Tenormin, reduced the Cardura by half, and added Lisinopril and 81 mg aspirin tab. I am curious as to the high score and the relationship to the thyroid. Any experiences that are similar?
