RESUMO
<p><b>OBJECTIVE</b>To explore the influence of Chinese medicine constitution type on the susceptibility of hypertensive patients to intracerebral haemorrhage.</p><p><b>METHODS</b>Primary hypertensive patients were studied and divided into the hypertension and the hypertensive intracerebral haemorrhage groups, depending on whether or not the patients had intracerebral haemorrhage. The demographic characteristics, physiological characteristics, living habits, biochemical tests, other chronic diseases, Chinese medicine constitution type, etc. were collected and compared between the two groups. The neurological deficit in the hypertensive intracerebral haemorrhage group was also compared among the different constitution types.</p><p><b>RESULTS</b>A total of 304 patients participated in this investigation, including 213 cases in the hypertension group and 91 cases in the hypertensive intracerebral haemorrhage group. The percentages of dampness-heat and qi-depression types in the intracerebral haemorrhage group were greater than those with the same types in the hypertension group (20.9% vs 6.1%, 22.0% vs 8.0%; P<0.05). The percentages of each constitution type were different between genders in both groups. In addition, there were more male cases (14/20) with qi-depression type and more female cases (7/8) with phlegm-dampness type in the hypertensive intracerebral haemorrhage group than those with the same types (3/17 and 9/34, respectively) in the hypertension group (P<0.05). The cases with phlegm-dampness and qi-depression types had greater levels of blood lipids in the intracerebral haemorrhage group than those with the same types in the hypertension group (P<0.05). Furthermore, the cases with the qi-deficiency type presented with a more severe neurological deficit than those with the other types (P<0.05).</p><p><b>CONCLUSIONS</b>Chinese medicine constitution type might have an impact on the susceptibility of hypertensive patients to have an intracerebral haemorrhage. The heat-dampness and qi-depression types might lead to greater susceptibility than the other types. In addition, the patient's gender and blood lipids might also influence the susceptibility along with the constitution type.</p>
