ABSTRACT
Objective: To compare the clinical characteristics and plasma level of N-terminal pro-brain natriuretic peptide (NT-proBNP) between the patients with hypertensive hypertrophic cardiomyopathy in elder age (HHCME) and the patients with hypertensive left ventricular hypertrophy (HTN-LVH). Methods: Our work included 2 groups, HHCME group,n=47 and HTN-LVH group,n=44. Duplex Doppler echocardiography was performed to determine left atrial diameter (LAd), left ventricular end-diastolic dimension (LVEDd), interventricular septal thickness (IVST), left ventricular ejection fraction (LVEF), velocity of early diastolic period (VE) and velocity of end-diastolic period (VA) in mitral valve oriifce. Plasma level of NT-proBNP was measured by ELISA. The above indexes were compared between 2 groups. Results:①Compared with HTN-LVH group, HHCME group presented decreased LVEDd and increased IVST, LVEF, allP0.05.②Plasma level of NT-proBNP was higher in HHCME group,P Conclusion: The plasma NT-proBNP level was higher in HHCME patients than that in HTN-LVH patients which indicated that HHCME patients may have worse prognosis. NT-proBNP might be helpful for differencing HHCME.
ABSTRACT
OBJECTIVE: This study is aimed to describe our experience with performing hemicraniectomy for treating patients with malignant cerebral infarction. This study also aimed at describing the difference between our experience and that of the published articles. METHODS: Ten patients who had anterior circulation territory cerebral infarction underwent decompressive hemicraniectomy for treating their life threatening brain swelling between August 2004 and October 2007. We retrospectively analyzed the patients' medical records and radiological films and we described the patients' clinical and radiological details. The outcomes were measured according to the case fatality rate at 2 weeks and the modified Rankin scale (mRS) at 9 months. We compared our institution's outcomes with the pooled analysis result of three randomized controlled trials (DESTINY, DECIMAL, HAMLET trial). RESULTS: Nine men and one woman were included in this study. Their mean age was 61.5 +/- 11.9 years, and the mean National Institute of Health Stroke Scale (NIHSS) score on admission was 17.3 +/- 6.0. Five patients died within 2 weeks after operation. Four patients had a mRS of 5 and one had a mRS of 4 at 9 months. Our series included elder patients (mean difference : 9.9~18.3 years) who had a low NIHSS score on admission (mean difference : -4.8~-6.8) as compared to that of the pooled analysis group. Our series revealed a higher proportion of an unfavorable outcome (mRS > or = 4) compared to that of the pooled analysis results (p=0.01). No patient in our series would have been eligible, according to the inclusion criteria, for inclusion in the pooled analysis studies. CONCLUSION: We think that the higher proportion of an unfavorable outcome in our series was a consequence of the elder age of our patients.
