Insights
High total cholesterol is linked to ischemic cerebrovascular diseases, especially in men under 60. Triglyceride levels play a lesser role, and HDL-cholesterol showed no significant reduction in patients compared to controls.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Biochemistry
Background:
- Ischemic cerebrovascular diseases, including transient ischemic attacks (TIA) and cerebral infarction, pose significant health risks.
- Lipid profiles, particularly serum cholesterol and triglyceride levels, are implicated in cardiovascular and cerebrovascular disease pathogenesis.
Purpose of the Study:
- To investigate the association between serum lipid levels (total cholesterol, triglycerides, HDL-cholesterol) and ischemic cerebrovascular diseases.
- To determine if specific lipid parameters are risk factors in different patient demographics (age, sex).
Main Methods:
- Serum lipid levels were analyzed in patients with TIA and cerebral infarction.
- Patients were age- and sex-matched with control groups for statistical comparison.
- Specific analyses included total cholesterol, triglycerides, HDL-cholesterol, and the HDL-cholesterol/total cholesterol ratio.
Main Results:
- Significantly higher mean total cholesterol was observed in male patients with TIA and cerebral infarction.
- Elevated total cholesterol was particularly noted in male TIA patients under 60.
- Higher triglyceride levels were found in younger males (TIA < 50) and older females (TIA 60-70).
- HDL-cholesterol levels did not show significant variation, except in older male cerebral infarction patients.
Conclusions:
- Total serum cholesterol levels appear to be a significant factor in the pathogenesis of ischemic cerebrovascular diseases, especially in men under 60.
- Serum triglyceride levels seem to play a less prominent role.
- No significant reduction in HDL-cholesterol was found in the studied patient groups compared to controls.
Abstract:
The serum cholesterol and triglycerid levels have been studied in 50 patients affected by transient ischaemic attacks (TIA) and in 89 patients suffering from cerebral infarction of non embolic origin. In 25 patients with TIA and in 59 patients with cerebral infarction, the HDL-cholesterol level and the HDL-cholesterol and total cholesterol ratio have also been determined. Every patient was matched with a control of the same age and sex for statistical proposal. The mean total cholesterol concentration was significantly higher in the male patients affected by TIA and cerebral infarction. Dividing the patients according to age, the mean total cholesterol level remained significantly higher only in the male patients with TIA under the age of 60. The mean triglycerid concentration was significantly higher as compared with the controls in the male patients with TIA under the age of 50 and in the female patients with TIA aged from 60 to 70. The HDL-cholesterol level, though lower than in controls, showed no significant variation both in patients with TIA and with cerebral infarction, excepting the male patients affected by cerebral infarction over the age of 70. The HDL-cholesterol and total cholesterol ratio was insignificantly lower than in controls both in TIA and in infarct patients. These results seem to emphasize the role of total serum cholesterol level in the pathogenesis of ischaemic cerebrovascular diseases particularly in the male patients under the age of 60. Less striking appears to be the role of serum triglycerid level. Finally we can't show a significant HDL-cholesterol reduction in our patients as compared with controls.
