High levels of Lipoprotein(a), raise the risk of recurring coronary heart disease.
Increased levels of Lipoprotein(a),a variant of 'bad cholesterol', in the bloodstream are a risk factor for recurrent coronary heart disease (CHD) in people aged 60 or over, according to the results of a new study that tracked the issue over the course of 16 years.
The results, suggest that current cholesterol-lowering medications may not be effective at reducing the risk of recurrent CHD – such as a heart attack – due to elevated Lp(a).
While previous research has indicated that high levels of Lp(a) are also an important risk factor in the development of CHD, most of these studies have looked at Lp(a) levels and the risk of a first CHD event. The current study looked at whether elevated Lp(a) is predictive of a second or recurrent CHD event. It involved 607 Australians aged 60 years and over, all with prevalent CHD, who were followed for 16 years as part of the Dubbo study. There were 399 incident CHD cases.
