二尖瓣狭窄伴心房颤动球囊二尖瓣成形术前抗凝及术后复律的临床探讨 总被引:2,自引:0,他引:2
对26例二尖瓣狭窄(MS)合并心房颤动(Af)的患者在行经皮球囊二尖瓣成形术(PBMV)前给大剂量肝素短程抗凝,并对其中19例在术后即给予同步直流电复律,探讨短程抗凝后PBMV的可能性及PBMV术后即刻电复律的影响因素。其结果表明:本组26例二尖瓣口面积(MVA)由0.92±0.2cm2扩大至1.95±0.37cm2,左房平均压(LAP)由3.12±1.27kPa降至1.42±0.85kPa,而左房内径(LAD)由52.7±8.1mm缩至42.5±5.9mm,26例均无血栓栓塞并发症及出血并发症;其中19例术后即刻行同步电复律者15例复律成功,成功率为78.9%。认为:MS合并Af患者PBMV术前大剂量肝素短程抗凝可缩短术前准备时间并达到预防血栓栓塞之目的,同时在Af病程较短、无巨大左房、球囊充盈程度良好、LAP下降显著、较好地控制心室率等因素基础上,可在PBMV术后即刻给予同步直流电复律。 相似文献

Chronic atrial fibrillation (AF) has often been associated with systemic embolization, and patients with mitral stenosis (MS) have the highest thromboembolic risk. Increased risk of thromboembolism could be in part due to impaired fibrinolytic function. Global fibrinolytic capacity (GFC) is an innovative technique for evaluating the entire fibrinolytic system.The aim of our study was to evaluate fibrinolytic activity in patients with rheumatic and nonrheumatic chronic AE To investigate fibrinolytic activity, we assessed GFC in peripheral blood samples of 32 patients with nonrheumatic AF (14 women; mean age, 56 +/- 1 years), 30 patients with rheumatic MS and AF (23 women; mean age, 35 +/- 9 years), and 32 patients with rheumatic MS and sinus rhythm (24 women; mean age, 36 +/- 8 years). The control group comprised 30 healthy adult subjects in normal sinus rhythm. Patients with chronic AF (rheumatic and nonrheumatic) had lower GFC than did the controls (P = .0001). The rheumatic AF group also showed decreased levels of GFC compared with the nonrheumatic AF group, with the rheumatic MS and sinus rhythm group, and with controls (P = .03, P = .02, P = .0001, respectively). GFC was lower in patients with rheumatic MS and sinus rhythm than in controls (P = .003). Although there were correlations between GFC and mitral valve area, transmitral mean gradient, left atrial diameter, and mitral calcification in patients with rheumatic MS, multivariate analysis showed only transmitral gradient as an independent factor affecting GFC. Patients with AF have decreased GFC, a finding that suggests the presence of a hypofibrinolytic state. Fibrinolytic dysfunction was more pronounced in rheumatic MS patients with AF than in those with nonrheumatic AF. Moreover, patients with rheumatic MS and sinus rhythm had decreased global fibrinolytic activity. Hypofibrinolysis documented by decreased GFC can be one of the important causes of increased risk of embolism in patients with AF and rheumatic MS. 相似文献

ObjectiveAtrial fibrillation is the most common sustained arrhythmia in patients with rheumatic heart disease (RHD). This study was conducted to determine the maintenance of sinus rhythm with amiodarone therapy following DC cardioversion (DCCV), early after successful balloon mitral valvuloplasty (BMV).MethodsPatients were randomized to amiodarone group and placebo group and their baseline characteristics were recorded. DCCV was done 48 h after BMV. After cardioversion, oral amiodarone was started initially 200 mg three times a day for 2 weeks, then 200 mg twice daily for two weeks followed by 200 mg once daily for 12 months. Patients in placebo group received DCCV alone without preloading amiodarone. After DCCV, they were given placebo for 12 months.ResultsThe 3 months follow-up period was completed by 77 patients (95%). Of them, 31 (77.5%) patients in amiodarone group and 14 (34.1%) in placebo group remained in sinus rhythm (SR). The 12 months follow-up period was completed by 73 patients (90.1%). Of them, 22 (55%) patients in amiodarone group and 7 (17.1%) in placebo group remained in SR.ConclusionWe conclude that amiodarone is more effective than placebo in maintenance of SR at the end of 3 months following successful cardioversion and more patients continued to remain in SR even at the end of 12 months without major serious adverse effects. 相似文献

AIMS: The randomized NASPEAF study included non-valvular with prior embolism and mitral stenosis patients in the same group. This is a sub-study to specially focus on the antithrombotic therapy in mitral stenosis. METHODS AND RESULTS: We analysed 311 patients with mitral stenosis, compared with 175 non-valvular atrial fibrillation patients with prior embolism, stratified by a history of previous embolism and assigned to anticoagulant therapy [target international normalized ratio (INR) = 2.0-3.0] or combined antiplatelet plus moderate intensity anticoagulant therapy. Median follow-up was 2.9 years. Outcomes were fatal and non-fatal embolism, stroke and myocardial infarction, sudden death, and death from bleeding. Combined therapy in mitral stenosis patients, compared with anticoagulant alone therapy, reduced the risk of vascular events by 58.3%. During equal therapy, the outcome annual rates were essentially the same in non-valvular and valvular patients [hazard ratio 0.90 (95% confidence interval 0.37-2.16), P = 0.81]. During anticoagulant alone therapy, the annual event rate in mitral stenosis patients without prior embolism was low (2.5%) and it was very high in patients with prior embolism (6.6%). CONCLUSION: Combined therapy was effective in mitral stenosis patients. Prior embolism patients are not efficiently protected with anticoagulant alone therapy for an INR of 2.0-3.0. 相似文献
