[Echocardiographic assessment of mitral annular calcification in hypertrophic cardiomyopathy with asymmetric septal hypertrophy and healthy elderly cases].
The prevalence and degree of mitral annular calcification (MAC) in elderly cases of hypertrophic cardiomyopathy with asymmetric septal hypertrophy (ASHCM) were studied in comparison with healthy elderly and chronic hypertensive elderly with concentric left ventricular hypertrophy (HT + LVH) by echocardiography. In seven elderly patients with ASHCM (mean age 77.3 +/- 8.1 years) severe MAC was observed in all cases (1 male and 6 females) and systolic anterior motion of the mitral valve (SAM) was present in 3 cases, incomplete in 2 and absent in 2 cases. Of 57 healthy elderly with a mean age of 78.8 +/- 8.8 years, 8 subjects (1 male and 7 females, 14%) showed MAC. The prevalence of MAC was 0% in the sixties, 14% in the seventies, 16% in the eighties and 29% in the nineties. MAC was severe in four subjects above eighty years old. In 3 cases with HT + LVH with a mean age of 72.3 +/- 4.7 years no MAC was observed and SAM was present in one, partially observed in one and absent in one case, respectively. Serum calcium (Ca) and phosphorus (P), reported to be related with the formation of MAC, and fasting blood sugar level (FBS) were evaluated. In healthy elderly with MAC, serum Ca was 8.78 +/- 0.46 mg/dl, P 3.55 +/- 0.37 mg/dl and FBS 97.75 +/- 29.01 mg/dl, P 3.55 +/- 0.37 mg/dl and FBS 97.75 +/- 29.01 mg/dl.(ABSTRACT TRUNCATED AT 250 WORDS)
