Role of Lipoprotein(a) Concentration and Apolipoprotein(a) Phenotype in Prediction of Coronary Events in General Population

The purpose of this study is to explore the role of lipoprotein(a) and apolipoprotein(a) phenotype in fatal and non-fatal cardiovascular disease (CVD) events risk in coronary disease patients divided on the basis of management strategy - medical, endovascular or open cardiac surgery.

Study Overview

Detailed Description

Between January 1993 and September 2006, we enrolled 1400 consecutive patients from the Atherosclerosis Department with known Lp(a) levels and coronary heart disease (CHD) verified by angiography. In accordance with clinical condition and angiography data were assigned them into three parallel treatment arms and followed up to 15 years. This study was conducted according to the principles of the Declaration of Helsinki and the Institutional Ethics Committee.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: conservative treatment
Men and women with stable CHD verified by angiography from one center and allocated to three treatment arms in real-world practice: 1. conservative treatment with statins, antiaggregants, antianginal drugs in standard dosage
Active Comparator: percutaneous coronary intervention
2. elective balloon angioplasty alone or stent implanation on the basement of drugs treatment
elective percutaneous coronary balloon angioplasty and/or stenting
Active Comparator: coronary artery bypass grafting
elective surgery myocardial revascularisation on the basement of drugs treatment
elective surgical myocardial revascularisation

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
non-fatal myocardial infarction and cardiovascular death
Time Frame: up to 15 years
we took a composite primary outcome measure because anticipated a low number of hard-end-points in each treatment arm
up to 15 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
non-fatal myocardial infarction and cardiovascular death and myocardial revascularisation and hospitalization for recurrent or unstable angina
Time Frame: up to 15 years
we chose a composite secondary outcome mesure as a standard for such type studies and to obtain a statistical difference between the groups
up to 15 years
