Lipoprotein(a): A Concealed Precursor of Increased Cardiovascular Risk? A Real-World Regional Lipid Clinic Experience
2020
Objective Lipoprotein(a) [Lp(a)] is an independent cardiovascular risk factor. We present real-life characteristics of patients with increased Lp(a) levels attending a University Lipid Clinic. Methods We retrospectively studied patients attending the University of Ioannina Hospital Lipid Clinic with Lp(a) levels ≥30 mg/dL who were followed-up for a median of 22 months. Results One hundred eight patients (median age 59 years, 49% females) were included with median Lp(a) levels 67 mg/dL (30–320). Of patients, 25.1% had established atherosclerotic cardiovascular disease (ASCVD): 11.1 and 5.6% positive personal history of myocardial infarction (MI) and stroke, respectively, 6.5% carotid artery disease and 1.9% lower extremities arterial disease (LEAD). In addition, 35.2% of participants had heterozygous familial hypercholesterolemia (heFH), 37.9% positive family history of premature ASCVD, 29.6% hypertension, 12.0% diabetes and 5.5% chronic kidney disease (CKD). Of patients, 67.6% were receiving statin therapy and 16.6% additional ezetimibe at baseline visit, and 83 and 35% were receiving statin treatment and additional ezetimibe, respectively, during follow-up. Low-density cholesterol (LDL-C) levels and LDL-Ccorrected for Lp(a) levels were significantly reduced in lipid-lowering therapy naive patients by 37 and 40% (p 0.05), respectively, during follow-up. Lp(a) levels increased by 9% (p Conclusion Our data confirm the high prevalence of established ASCVD, hFH and positive familial history of premature ASCVD in patients with elevated Lp(a) levels. Lp(a) levels slightly increased during follow-up.
