Association of Lipoprotein(a) With Cardiovascular and Cerebrovascular Disease in a Nationally Representative Cohort of Germany.
Population-based data on the distribution of lipoprotein(a) (Lp[a]) within the German population are lacking.
The aim of the study was to determine the age- and sex-specific Lp(a) distribution in Germany and analyze its association with different types of cardiovascular disease (CVD).
We analyzed cross-sectional data from the German National Health Interview and Examination Survey 1998, a population-based study representing the German adult population's health status from 1997 to 1999. We examined serum Lp(a) according to demographics and investigated associations between Lp(a) and history of self-reported CVD. We tested Lp(a) in spline analysis on continuous scales and as dichotomous Lp(a) thresholds.
In the German National Health Interview and Examination Survey 1998 (n = 6,657), median Lp(a) was 15.3 mg/dL (Q1-Q3: 5.6, 43.1). Lp(a) levels ≥50 mg/dL were present in 21.6%. Men had substantially higher median Lp(a) than women (22.1 mg/dL vs 10.3 mg/dL). Median Lp(a) levels were significantly higher in individuals with than without a history of atherosclerotic cardiovascular disease (ASCVD) but did not significantly differ between people with and without venous thrombosis. In logistic regression analysis with splines, higher Lp(a) levels were associated with a higher probability of a history of CVD. In logistic regression analyses, Lp(a) ≥50 mg/dL was associated with a history of ASCVD (OR: 1.36 [95% CI: 1.04-1.78]; P = 0.023).
About 1 in 5 German individuals from a prestatin era population had Lp(a) levels ≥50 mg/dL. Higher levels were independently associated with ASCVD, but not with venous thrombosis. These findings provide a basis for future prospective studies to define the role of Lp(a) in CVD risk in the German population.
