作者： Wenli Zhang Shiwen Wang Rui Chen Mohan Liu Lin Wang Lei Gao Caiyi Lu institute of geriatric cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China

Objective To determine whether sleep-disordered breathing (SDB) may lead to nocturnal myocardial ischemia and whether the severity of this ischemia may be relieved by nasal continuous positive airway pressure (CPAP). Methods Overnight polysomnogram examination and simultaneous 3-channel Holter monitoring were performed on 76 patients with moderate to severe SDB and no history of coronary heart disease. All the cases were treated with CPAP for one night. ST depression was defined as a ST segment decrease of more than 1 mm from baseline and lasting 1 min or more. The total duration (minutes) of ST depression was indexed to the total sleep time (minutes per hour of sleep). Results Twenty-eight patients (37%) showed ST segment depression during their sleep. Before CPAP treatment, the respiratory disturbance index (RDI) and arousal index were significantly higher during periods of ST depression than when ST segments were isoelectric, whereas no significant difference was found in blood oxygen saturation (SaO2). After the CPAP treatment of patients with ST depression, the duration of ST depression was significantly reduced from 36.8±18.9 to 11.4±13.2 min/h (P<0.05). ST depression-related indexes, including RDI, arousal index and the percentage of sleep time spent at SaO2 below 90% (TS90/ TST), were all significantly decreased, with RDI from 63.4±23.8 to 8.1±6.6 /h, arousal index from 51.2±18.9 to 9.6±5.4 /h, and TS90/ TST from 50.6±21.4 to 12.9±14.7% (P<0.05). Conclusion ST-segment depression is rather common in patients with moderate to severe SDB, and CPAP treatment can significantly reduce the duration of ST depression. ST depression in these patients may reflect the myocardial ischemia that really exists and the non-ischemic changes associated with recurrent SDB.

Journal of geriatric cardiology 2006年第2期3卷 67-70页

作者： Yuxiao ZHANG Caiyi LU Qiao XUE Peng LIU Wei YAN Rui CHEN institute of geriatric cardiology General Hospital of Chinese PLA Beijing 100853 China Institute of Geriatric Cardiology General Hospital of Chinese PLA Beijing 100853 China Institute of Geriatric Cardiology General Hospital of Chinese PLA Beijing 100853 China Institute of Geriatric Cardiology General Hospital of Chinese PLA Beijing 100853 China Institute of Geriatric Cardiology General Hospital of Chinese PLA Beijing 100853 China Institute of Geriatric Cardiology General Hospital of Chinese PLA Beijing 100853 China

Objective To assess the safety and efficacy of a novel biodegradable polymer and rapamycin-coating stent, the EXCEL stent, in the treatment of coronary artery disease (CAD), as compared with the CypherTM stent. Methods In this prospective, non-randomized study, 60 consecutive patients with symptomatic CAD received either an EXCEL stent (n=32), or a CypherTM stent(n=28),according to their respective treatment intention. Follow-up angiography was performed at a mean of 180±40 days. The primary endpoint of the study was the occurrence of a major adverse cardiac event (MACE), including death, myocardial infarction, or target-vessel revascularization during the 6 months after stenting. The secondary end points included the in-stent late luminal loss (LLL), percentage of in-stent stenosis of the luminal diameter, and the rate of restenosis (luminal narrowing of 50 percent or more) at 6 months. Results There were no significant differences between the two groups in baseline characteristics, including the distribution of target vessel and lesion types. During the follow up period of 6 months, there were no occurrences of MACE in either group. Twenty-seven patients(84%) in the EXCEL group and 10 (36 %) in the CypherTM group underwent quantitative coronary angiography at 6 months. For these patients, no restenosis occurred, and there were no differences in the in-stent stenosis of the luminal diameter (5.98±5.52% vs 5.21 ±6.3%,P＞0.05) and the LLL (-0.02±0.09 mm vs -0.01±0.07 mm, P＞0.05). Conclusions Compared with the CypherTM stent, the EXCEL Stent with biodegradable polymer and rapamycin-coating showed similar efficacy in the prevention of neointimal proliferation, restenosis, and associated clinical events in CAD patients.

Journal of geriatric cardiology 2009年第1期6卷 38-41页

作者： Mei Zhu Mohan Liu Xinhong Guo Shiwen Wang institute of geriatric cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China Institute of Geriatric Cardiology Chinese PLA General Hospital Beijing 100853 China

Objective To investigate the relationship of blood pressure circadian rhythm with myocardial hypertrophy and the changes of autonomic nerve function in patients with essential hypertension (EH). Methods Eighty-two female patients with essential hypertension (EH) underwent 24-hours ambulatory blood pressure monitorings (ABPM), dynamic electrocardiogram (Holter) and echocardiography examination. Patients were classified into non-dipping group (n=40) and dipping group (n=42) according to the result of ABPM. Left ventricular mass index (LVMI), heart rate variability (HRV) in time domain (including SDNN, SDANN, rMSSD, PNN50) and heart rate turbulence (HRT) parameters (including turbulence onset [TO] and turbulence slope [TS]) were measured. Results Compared with those in dipping group, patients in non-dipping group have higher incidence of LVH (19.0% vs 52.5%, P<0.01), greater mean LVMI (112.39±12.79 g/m2 vs 121.98±13.35 g/m2, P<0.01), decreased PNN50 and rMSSD. TS value was decreased while TO was increased in non-dipping group compared with those in dipping group (both P <0.01); patients with LVH showed decreased TS and increased TO, compared with those without LVH. Conclusion In female patients with EH, non-dipping blood pressure circadian is associated with higher incidence of LVH. The HRV and HRT were more remarkably blunted in non-dipping patients, as well as those with LVH.

Background and objective To assess the predictive value of C-reactive protein(CRP) for major adverse cardiac events and the association between CRP level and the coronary lesion morphology and extent in patients with coronary heart disease (CHD).Methods CRP was measured on admission in 177 consecutive elderly (age≥60 years) patients with CHD who underwent coronary angiography. Patients were divided into high CRP group (CRP≥3mg/L) and normal CRP group (CRP ＜3mg/L). The association between CRP levels and the coronary lesion features, including severity of stenosis (mild, moderate, severe), extent of lesion (diffused or nondiffused), eccentricity of the plaque (eccentric or non-eccentric) were analyzed. Patients were followed up for a mean of 8 months for the occurrences of major adverse cardiac events (MACE). Results Compared with patients in normal CRP group, patients in high CRP group were more frequently to have unstable angina, multi-vessel, diffuse, eccentric lesions, positive remodeling, and non-smooth plaques (P＜0.01). Kaplan-Meier analysis showed patients in high CRP group had a significantly lower MACE-free survival rate than patients in normal CRP group (Log-rank = 12.0, P＜0.01); Cox regression analysis indicated CRP level as an independent predictor for the occurrence of MACE (OR=3.16, P＜0.05) Conclusions High CRP level is associated with more extend, severe and eccentric coronary lesions and is an independent predictor for MACE in elderly patients with CHD.
