Overview
Aortic sclerosis is non-obstructive degeneration of the aortic valve that presents predominantly in patients over 65 years of age who have risk factors for coronary artery disease. Because aortic sclerosis is associated with coronary artery disease risk factors, it is also associated with a significant increase in the risk of cardiovascular death, myocardial infarction even in the absence of hemodynamically significant left ventricular outflow tract obstruction. However, it remains unclear whether aortic sclerosis is independently associated with risk or merely a marker of coexistent cardiovascular risk factors.[1]
Risk Factors for Aortic Sclerosis
- Based on a large cohort study,[2][3] independent clinical factors associated with aortic sclerosis include:
- Age (twofold increased risk for each 10-year increase in age)
- Male gender (twofold excess risk)
- Present smoking (35% increase in risk)
- History of hypertension (20% increase in risk) with subsequent left ventricular hypertrophy [4]
- Height
- Elevated lipoprotein(a) and elevated low density lipoprotein cholesterol levels
- End-stage renal disease on maintenance dialysis.[5][6]
Aortic Sclerosis as a Risk Factor for Coronary Artery Disease
- In addition to traditional risk factors for coronary artery disease, the presence of multiple calcium deposits in the mitral annulus, aortic valve or aortic root have been shown to be a predictor of coronary artery disease among elderly patients.[7][8]
