These results may be the result of conflicting multifactorial factors, such as race, duration of follow-up, gender, pre-PCI status (stable CVD or acute myocardial infarction, etc.), and method of Lp(a) measurement, Therefore, we need more long-term large-sample clinical trials to further explore the effect of Lp(a) on long-term prognosis after PCI. This evidence concerns the gene LPA and myocardial infarction.
