Influence of hypertension, lipometabolism disorders, obesity and other lifestyles on spontaneous intracerebral hemorrhage.
OBJECTIVE
To investigate whether hypertension, abnormal lipometabolism, obesity, cigarette smoking and alcohol drinking affect the intracerebral hemorrhagic volumes (IHV) in patients with spontaneous intracerebral hemorrhage (SIHP), and to explore the roles of these factors in spontaneous intracerebral hemorrhage (SIH).


METHODS
Five hundred patients with acute SIH and 200 healthy adult volunteers (HAV) were enrolled in a study of independently randomized controlled design, in which the levels of systolic pressure (SP) and diastolic pressure (DP), and total cholesterol (TCH), triacylglycerols (triglycerides, TG), high density lipoprotein cholesterol (HDL-CH), low density lipoprotein cholesterol (LDL-CH) in serum as well as the level of erythrocytic membrane cholesterol (EM-CH) were measured, and the body mass index (BMI), daily cigarette smoking consumption (DCSC) and daily pure alcohol consumption (DPAC) were calculated.


RESULTS
Compared with the average parameters in the HAV group, those of SP, DP, TG, LDL-CH and BMI in the SIHP group were significantly increased (P < 0.0001), while those of HDL-CH and EM-CH were significantly decreased (P < 0.0001). The linear regression and correlation analysis showed that with increased SP, DP, LDL-CH, BMI, DCSC, DPAC and aging as well as decreased HDL-CH and EM-CH, the IHV levels in SIHP were increased gradually (P < 0.0001-0.01). The linear stepwise regression analysis suggested that there existed a close correlation among the values of SP, DP, TCH, TG, HDL-CH, LDL-CH, EM-CH, BMI, DCSC, DPAC, age and IHV of the SIH patients, and that Y = -12.4583 + 0.1127SP -1.1977EM-CH + 0.9788LDL-CH + 0.2477BMI + 0.0382DCSC + 0.0248DP, P < 0.0001 approximately 0.05.


CONCLUSIONS
The findings in the present study suggest that significantly increased systolic and diastolic pressure, low density lipoprotein cholesterol, body mass index and daily cigarette smoking consumption, and significantly decreased erythrocytic membrane cholesterol may be likely the main factors affecting intracerebral hemorrhagic volumes in patients with acute spontaneous intracerebral hemorrhage.
