Unusual Tachycardia Association In A patient Without Structural Heart Disease

We report an unusual association of persistent atrial flutter and bundle branch re-entrant ventricular tachycardia in a young patient without structural heart disease. Atrial flutter masked the infra-Hisian conduction disease, was fundamentally dependent on a long PR interval, and could be a possible trigger of ventricular tachycardia.     

Alpha-chain Disease with Clinical,Immunological, and Histological Recovery

Clinical, immunological, and histological recovery in a patient with alpha-chain disease is described. The patient, a 27-year-old Greek man, presented with severe steatorrhoea, abdominal pain, oedema, and hypogammaglobulinaemia. Treatment with tetracycline produced only temporary remission. Intermittent therapy with prednisone and cyclophosphamide together with antibiotics was followed by clinical recovery, return of histological appearances of the small intestine to normal, and disappearance of free alpha-chain protein from the serum. The patient remained well one year later without treatment.     

Effect of Aerobic Training on Heart Rate Recovery in Patients with Established Heart Disease; a Systematic Review

Background

Although a delayed decrease in heart rate during the first minute after graded exercise has been identified as a powerful predictor of overall mortality in cardiac patients, the potential to influence this risk factor by aerobic training remains to be proven.

Objective

The aim was to study the relationship between aerobic training and Heart Rate Recovery (HRR) in patients with established heart disease.

Methods

(Quasi) randomized clinical trials on aerobic exercise training in adults with established heart disease were identified through electronic database and reference screening. Two reviewers extracted data and assessed the risk of bias and therapeutic validity. Methodological validity was evaluated using an adapted version of the Cochrane Collaboration’s tool for assessing risk of bias and the therapeutic validity of the interventions was assessed with a nine-itemed, expert-based rating scale (CONTENT). Scores range from 0 to 9 (score ≥ 6 reflecting therapeutic validity).

Results

Of the 384 articles retrieved, 8 studies (449 patients) were included. Three of the included studies demonstrated adequate therapeutic validity and five demonstrated low risk of bias. Two studies showed both adequate therapeutic validity and a low risk of bias. For cardiac patients aerobic exercise training was associated with more improvement in HRR compared to usual care.

Conclusion

The present systematic review shows a level 1A evidence that aerobic training increases HRR in patients with established heart disease.     

妊娠合并心脏病812例临床分析

目的:探讨妊娠合并不同种类心脏病患者的母儿预后.方法:对我院2002年3月至2012年5月间收治的812例妊娠合并心脏病患者的有关临床资料进行回顾分析.结果:1).研究的470例妊娠合并先心病患者平均年龄为30.0±4.7岁,101例妊娠合并风心病患者平均年龄为30.1+ 4.8岁,241例妊娠合并其它心脏病患者平均年龄为29.1+ 4.5岁.470例妊娠合并先心病患者初产妇为425例,101例妊娠合并风心病患者初产妇为74例,241例妊娠合并其它心脏病患者初产妇为200例.三组患者的心脏病史相比较,差异有统计学意义;三组并发症相比较,差异无统计学意义.2).妊娠合并先心病和风心病从2002年到2012年每年的发病均呈递增的趋势;妊娠合并其它心脏病的发病高峰在2007年至2010年.3).妊娠合并先心病组同妊娠合并风心痛组及妊娠合并其它心脏病组的新生儿不良结局的比较结果中,新生儿死亡及早产比较,差异有统计学意义.窒息、低体重儿、脐绕颈、胎儿窘迫的比较,差异无统计学意义.4).在母亲妊娠结局方面,三组的剖宫产、胎盘残留、产褥病率及脐带异常相比较,差异均无统计学意义.心律失常及其它并发症比较,P＜0.001,差异有统计学意义.结论:对于妊娠合并不同心脏病患者的母儿预后的影响有待更多研究,加强孕前心脏病史的管理可以显著改善母儿预后,临床上应重视合并心脏病孕妇的孕前咨询、产前检查和孕期保健,强调对其妊娠期、分娩期、产褥期进行多学科、规范化管理,割宫产是较为安全的分娩方式.
