Abstract
Background: In 2020 there were estimated to be 25 million deaths each year from cardiovascular disease; most of them being coronary heart disease. Traditional risk factors such as smoking, hypertension, diabetes, dyslipidemia reported to affect only 50% of the prevalence and degree of coronary heart disease. It pushes a lot of research on non-traditional risk factors one of which is lipoprotein (a). Levels of Lp (a) also reflects the degree of severity and is associated with the number of coronary arteries involved. The purpose of this study was to determine the relationship of Lp (a) level with the complexity of coronary artery lesion.Methods: This was a cross-sectional study. Subjects were male and women patients aged between 20 to 60 years who underwent coronary angiography for theirs STEMI, NSTEMI, unstable angina pectoris, and stable angina pectoris. Correlation between elevated Lp (a) with the complexity of coronary artery lesion was performed by Pearson test. If the distribution was abnormal we used Spearman test.Result: Number of samples was 64 subjects (49 men and 15 women). The result showed a significant positive correlation between Lp (a) level and complexity of coronary vessel lesion that counted by SYNTAX score (p 0,004) even though the coefficient correlation is weak (r 0, 33).Conclusion: The higher Lp (a) level shows bigger SYNTAX score which means the coronary vessel lesion more complex.Bangladesh Journal of Medical Science Vol.15(3) 2016 p.362-367
Highlights

Many of coronary heart disease patients who have normal levels of dyslipidemia or slightly increase. It pushes a lot of research on non-traditional risk factors such as fibrinogen, homocysteine,tissue plasminogen activator (t-PA), and lipoprotein (a)[4]
Correlation of Lp (a) with atherosclerosis and acute coronary syndrome (ACS) is mediated by: 1) a partial homology between apo (a) with plasminogen, compete for binding to fibrin and plasminogen receptor in endothelium[5, 2] the oxidation of Lp (a) and uptake of Lp (a) by macrophages in the arterial wall as a process that occurs in the Low Density Lipoprotein (LDL)[6].Research has shown that Lp (a) is a risk factor ACS
Summary
Cardiovascular disease is the leading cause of death in developed countries[1]. In 2020 there were estimated to be 25 million deaths each year from cardiovascular disease almost half of them due to coronary heart disease[2,3]. Correlation of Lp (a) with atherosclerosis and acute coronary syndrome (ACS) is mediated by: 1) a partial homology between apo (a) with plasminogen, compete for binding to fibrin and plasminogen receptor in endothelium[5, 2] the oxidation of Lp (a) and uptake of Lp (a) by macrophages in the arterial wall as a process that occurs in the Low Density Lipoprotein (LDL)[6].Research has shown that Lp (a) is a risk factor ACS Another interesting thing is the level of Lp (a) reflects the degree of severity and is associated with the number of coronary arteries that terlibat[7, 8, 9].
