Lipoprotein(a) is an independent risk factor for multiple cerebral infarctions
1Department of Endocrinology and Metabolism, Toranomon Hospital, Tokyo, Japan.
Abstract:
In an attempt to ascertain whether Lp(a) is a risk factor for multiple cerebral infarctions (MCI), we have studied 83 patients with proven MCI and 39 subjects without MCI by computed tomography (CT). Seventy-one patients with non-insulin-dependent diabetes mellitus (NIDDM) were included: 52 with and 19 without MCI. Serum Lp(a) levels were significantly higher in patients with MCI than in subjects without MCI. There were no differences in serum Lp(a) levels between NIDDM and non-diabetic patients with MCI. The logistic regression analysis revealed that Lp(a) and hypertension were independent risk factors for the cerebral event. The current study demonstrated that Lp(a) and hypertension are significant risk factors for multiple cerebral infarctions.
Insights
Elevated lipoprotein(a) (Lp(a)) levels are a significant risk factor for multiple cerebral infarctions (MCI). This finding holds true regardless of diabetes status, highlighting Lp(a) as a key indicator for stroke risk.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Clinical Biochemistry
Background:
- Cerebral infarctions represent a significant health burden.
- The role of lipoprotein(a) (Lp(a)) as a risk factor for multiple cerebral infarctions (MCI) requires further elucidation.
- Non-insulin-dependent diabetes mellitus (NIDDM) is a known risk factor for vascular events.
Purpose of the Study:
- To investigate the association between serum Lp(a) levels and the presence of MCI.
- To determine if Lp(a) is an independent risk factor for MCI.
- To explore the interaction between Lp(a), hypertension, NIDDM, and MCI.
Main Methods:
- A case-control study involving 83 patients with proven MCI and 39 control subjects.
- Computed tomography (CT) was used to confirm MCI.
- Serum Lp(a) levels were measured and analyzed in relation to clinical data, including hypertension and NIDDM status.
Main Results:
- Serum Lp(a) levels were significantly higher in patients with MCI compared to control subjects.
- No significant difference in Lp(a) levels was observed between diabetic and non-diabetic patients with MCI.
- Logistic regression analysis identified Lp(a) and hypertension as independent risk factors for MCI.
Conclusions:
- Elevated serum Lp(a) is a significant risk factor for multiple cerebral infarctions.
- Hypertension is also an independent risk factor for MCI.
- Lp(a) appears to be a relevant biomarker for predicting cerebral infarction risk, irrespective of diabetes status.
