NPPB and Stroke: Table 1 summarized the baseline characteristics for each group. Patient age significantly increased across ascending Lp(a) quartiles (P = 0.006). Those in upper Lp(a) quartiles exhibited reduced systolic blood pressure (P = 0.019) and elevated TC (P = 0.001), LDL-C (P < 0.001), BNP (P = 0.043), and hs-CRP (P = 0.048). A significantly greater proportion of patients in the higher Lp(a) quartiles had a history of stroke (P = 0.014). Additionally, TG levels were lower in patients in the upper Lp(a) quartiles (P = 0.006).
