Mitral anular calcium (MAC) is a degenerative process common in elderly patients.1-6 Roberts and colleagues1,2 suggested that MAC is accelerated by conditions that increase left ventricular pressure and by conditions that accelerate atherosclerosis. Nair et al4 reported that patients with MAC had a higher level of serum phosphorus and product of serum calcium and phosphorus and an increased prevalence of systemic hypertension and diabetes mellitus than a control group. During a blinded, prospective study of the prevalence of MAC in an unselected population of persons older than 62 years in a long-term health care facility, we obtained data to correlate serum total cholesterol, high-density lipoprotein cholesterol, triglycerides, calcium, phosphorus, and product of calcium and phosphorus, diabetes mellitus, aortic valve stenosis and history of systemic hypertension with the presence or absence of MAC.
