TL;DR
In men with CAD and elevated LDL-C, Lp(a) levels were dominant correlates of baseline disease severity, its progression, and event rate over 2.5 years.
Abstract
In men with CAD and elevated LDL-C, Lp(a) levels were dominant correlates of baseline disease severity, its progression, and event rate over 2.5 years. However, with substantial LDL-C reductions, persistent elevations of Lp(a) were no longer atherogenic or clinically threatening. This provides a possible direction for treatment in such patients with elevated Lp(a) and LDL-C.

In men with coronary artery disease who were at high risk for cardiovascular events, intensive lipid-lowering therapy reduced the frequency of progression of coronary lesions, increased the frequencyof regression, and reduced the incidence of cardiovascular events.

JAMALp(a) Lipoprotein as a Risk Factor for Myocardial Infarction
775 Citations1986George G. Rhoads
It is concluded that Lp(a) is an important attribute that should often be considered when coronary heart disease risk is assessed and was not explained by differences in total cholesterol levels, high-density lipoprotein or low-density lipid levels, subscapular skin fold, systolic blood pressure, history of smoking, alcohol consumption, or age.

630 Citations1986Victor W. Armstrong, Peter Cremer +6 more
The data suggest that increasing LDL concentrations markedly increase the risk of coronary artery disease due to elevated Lp(a) levels, independent of the known risk factors smoking, hypertension and diabetes.

An elevated level of lipop protein(a) is a strong risk factor for CHD in patients with familial hypercholesterolemia, and the increase in risk is independent of age, sex, smoking status, and serum levels of total cholesterol, triglyceride, or high-density lipoprotein cholesterol.

499 Citations1993Paul M. Ridker
The data do not support the use of Lp(a) level as a screening tool to define cardiovascular risk among this population of predominantly middle-aged white men, and no evidence of association between Lp-a level and risk of future MI is found.

The data are consistent with the concept that an elevated Lp(a) level is an independent risk factor for CHD in hypercholesterolemic white men.

465 Citations1990Joseph Loscalzo, Michael S. Weinfeld +2 more
It is demonstrated that, like plasminogen, Lp(a) binds to fibrin, and it is suggested that Lp (a) influences the fibrinolytic system and probably does so by virtue of thefibrin binding properties conferred by the kringle repeats of apo(a).

The results suggest that the apoprotein of lipoprotein [a] is composed of two subunits which are similar in molecular weight and are held together by one or more disulfide bonds.

424 Citations1990M. Sandkamp, Harald Funke +3 more
The data suggest that an increased concentration of lipoprotein(a) constitutes an independent risk factor for early myocardial infarction and the concentrations of Lp (a) and LDL cholesterol (apolipoprotein B) in serum are under separate metabolic control.

The GRIPS data strongly support strategies for the identification and treatment of persons at increased MI risk which focus on LDL cholesterol, but Lp(a) and fibrinogen have to be seriously considered as additional risk factors and should be included in diagnostic panels for the estimation of MI risk.
