Low T3 vs low T3T4 euthyroid sick syndrome in septic shock patients:A prospective observational cohort study

BACKGROUND Both phases of euthyroid sick syndrome(ESS)are associated with worse prognosis in septic shock patients.Although there are still no indications for supplementation therapy,there is no evidence that both phases(initial and prolonged)are adaptive or that only prolonged is maladaptive and requires supplementation.AIM To analyze clinical,hemodynamic and laboratory differences in two groups of septic shock patients with ESS.METHODS A total of 47 septic shock patients with ESS were divided according to values of their thyroid hormones into low T3 and low T3T4 groups.The analysis included demographic data,mortality scores,intensive care unit stay,mechanical ventilation length and 28-day survival and laboratory with hemodynamics.RESULTS The Simplified Acute Physiology Score II score(P=0.029),dobutamine(P=0.003)and epinephrine requirement(P=0.000)and the incidence of renal failure and multiple organ failure(MOF)(P=0.000)were significantly higher for the low T3T4.Hypoalbuminemia(P=0.047),neutrophilia(P=0.038),lymphopenia(P=0.013)and lactatemia(P=0.013)were more pronounced on T2 for the low T3T4 group compared to the low T3 group.Diastolic blood pressure at T0(P=0.017)and T1(P=0.007),as well as mean arterial pressure at T0(P=0.037)and T2(P=0.033)was higher for the low T3 group.CONCLUSION The low T3T4 population is associated with higher frequency of renal insufficiency and MOF,with worse laboratory and hemodynamic parameters.These findings suggest potentially maladaptive changes in the chronic phase of septic shock.

Thyroxine treatment for elderly patients with heart failure and sick euthyroid syndrome

Objectives To evaluate the effect of thyroid hormone therapy with low dose of thyroxin on cardiac function in elderly patients with heart failure and sick euthyroid syndrome.Methods Forty-seven patients(33 males and 14 females,mean age 85.9+4.6 years,ranging from 80 to 99 years)with chronic heart failure(NYHAⅡ-Ⅳ)and low triiodothyronine(T_(3))state were randomly allocated to the treatment group or control group.The treatment group patients received oral administration of levothyroxine sodium(Euthyrox)25-50mg/d in addition to conventional therapy of heart failure,whereas patients in control group were given conventional therapy only.Serum level of total T_(3)(TT_(3)),free T_(3)(FT_(3)),total thyroxine(TT_(4)),free thyroxine(FT_(4)),and thyroid-stimulating hormone(TSH)were determined.For both groups,left ventricular ejection fraction(LVEF)and stroke volume(SV)were assessed by two-dimensional echocardiography before and at 8 weeks after treatment.The changes of these parameters after the treatment were evaluated by adjusting heart rate in the two groups.Results The reduced serum T_(3) level in the treatment group was corrected after thyroid hormone therapy,and these patients had a significant improvement in cardiac function after treatment.By contrast,in the control group only changes of serum TT_(3) and TT_(4) levels and SV and LVEF after treatment were statistically significant.The heart rate-adjusted mean SV and LVEF in both groups were also increased,which was significantly greater in the treatment group than in the control group.Conclusion In the elderly patients with heart failure and sick euthyroid syndrome,addition of thyroxine at a low dosage to the conventional treatment could effectively improve the low T_(3) state and cardiac function independent of changes of heart rate.

Elevated thyroid stimulating hormone levels are associated with metabolic syndrome in a Chinese community-based population of euthyroid people aged 40 years and older

This study investigated whether high-normal thyrotropin（TSH） levels are associated with metabolic syndrome in euthyroid Chinese people≥40 years old.Clinical and metabolic factors were assessed in 2,356 subjects（40-77 years old） with TSH levels in the normal range（0.35-5.00 mU/L）.Using 2.50 mU/L as the cut-off point of TSH level within the normal range,we divided subjects into the high-TSH（2.50-5.00 mU/L;n= 1,064） and low-TSH（0.35-2.50mU/L;n= 1,292） group.The results showed that the mean levels of body mass index（BMI）,total cholesterol（TC）,low density lipoprotein cholesterol（LDL-C）,and fasting plasma glucose（FPG） were higher in the high-TSH group and TSH levels were significantly positively con-elated with BMI,LDL-C,TC,and FPG.The prevalence of central obesity,hypertriglyceridemia,low high density lipoprotein cholesterol（HDL-C）,and high FPG（〉5.60 mmol/L） was significantly higher in females and subjects with high-TSH levels.Metabolic syndrome was also more prevalent in the high-TSH group.People over the age of 40 years with high-normal TSH levels had a 1.2-fold increased risk of metabolic syndrome,compared with those with low-normal TSII levels,after adjusting for age and gender.In conclusion,high normal TSH is a risk factor for metabolic syndrome in people ≥40 years old.

Anesthetic Management of a Patient with Sick Sinus Syndrome during General Anesthesia for Maxillofacial Surgery

Sick sinus syndrome (SSS) is a generalized abnormality of cardiac impulse formation. Patients with SSS occasionally need temporary pacing during general anesthesia. The most common issue arising in the perioperative period is electromagnetic interference with device function. We report a case of a 66-year-old man who required temporary cardiac pacing during maxillary cyst extirpation using electrocautery.

Headache and sick sinus syndrome:A case report

BACKGROUND Sick sinus syndrome is a common disease in cardiology.Typical symptoms include palpitations,dizziness,shortness of breath,chest tightness,and amaurosis.However,to date,there are no known reports of sick sinus syndrome presenting with headache.Whether there is a correlation between headache and sick sinus syndrome merits further research.In this report,we describe a case of headache induced by sick sinus syndrome.CASE SUMMARY A 73-year-old female patient presented to our department with the chief complaint of recurrent paroxysmal headache for more than 7 years.The patient described paroxysmal palpations,usually headache occurring after palpitation.Her blood pressure was normal when the most recent headache occurred.A magnetic resonance imaging study and magnetic resonance angiography of the head at another center were normal.A clinical neurological examination was negative.A 24-h Holter electrocardiogram monitoring study showed sick sinus syndrome.The patient received dual chamber pacing implantation and was administered drug therapy to control ventricular rate.The patient’s paroxysmal headaches and palpitations had resolved within 1 year,confirmed via a follow-up telephone call.CONCLUSION After dual-chamber pacing implantation and drug therapy administration to control the ventricular rate,the patient’s paroxysmal headaches and palpitations had resolved within 1 year,confirmed via a follow-up telephone call.We believe that the headaches were related to the patient’s sick sinus syndrome.

Sick sinus syndrome associated with hypopituitarism:a case report and literature review

Though an association between autoimmune diseases and sick sinus syndrome has been reported,there has been no report on the association of hypopituitarism and sick sinus syndrome.Herein,we provide the first case report of hypopituitarism accompanying sick sinus syndrome in a 51-year-old woman presented to our hospital with syncope due to cardiac arrest.The patient was successfully managed by pacemaker installation and hormone replacement therapy.

Rong Shuan Jiao Nang in the treatment of acute mountain sickness and high altitude myocardial ischemic syndrome in Yushu

To evaluate the therapeutic effects of Rong Shuan Jiao Nang （RSJN） on treatment of acute mountain sickness （AMS） and high altitude myocardial ischemic syndrome in workers in Yushu, three groups were studied： group A （60 patients with AMS, given RSJN）, group B （15 patients with altitude myocardial ischemic syndrome, given RSJN）, and group C （control, without drugs）. All studied subjects were lowland workers who were first time entry to Yushu for work at an altitude of 4 250 m. During the course of treatment, a routing physical examina- tion was performed, AMS Lake Louise Scores were estimated, arterial oxygen saturation （SaO2）, electrocardiography and hemoglobin concentration were measured before and after using RSJN for 10 days. In group A, the effective rate was 68 %, symptomatic improvement in 54 cases （90 %） within 5 days. In group B, the effective rate was 93 %, episodes of angina pectoris stopped in 12 patients within 3 - 7 days, one lasted 8 days. After treatment, the level of SaO2 increased 15.5 %, 21.8 % and 5.6 % in group A, group B and group C, respectively. RSJN tak- en at the start of the arrival at Yushu can decrease AMS scores and facilitate cure. If taken after the illness has begun, RSJN may help lessen symptoms, especially effectively improved angina pectoris of the high altitude myocardial ischemic syndrome. Symptoms usually subside after 3 - 8 days. RSJN should be continually used lbr at least 7 days after ascent.

辨证论治以减少血清病治疗中激素的应用

将中医“辨证论治”思维与现代医学对于糖皮质激素作用机制的认识相结合,提出通过辨证运用中药可替代激素调用肾阴、引水救火之功效,进而减少激素对血清病患者的不良反应,不伤其肾阴,最终达到安全有效治愈患者的目的。临证中将血清病主要辨证为风热犯表、热毒入营、邪犯肺卫以及风湿热痹4种证型。风热犯表者,主以疏风清热,解表止痒;热毒入营,则应清热凉血,解毒护阴;邪犯肺卫者,着重辛凉透表,清宣肺卫;风湿热痹,则需清热利湿,宣痹通络。

病态窦房结综合征动物模型的研究进展

病态窦房结综合征(sick sinus syndrome,SSS)是窦房结及其周边组织发生了损伤,使窦房结发生了兴奋、传导功能紊乱,从而引起了一系列的心律失常疾病。为更好地探索SSS发病机制,并为其治疗研究提供依据,建立出能够模拟人类窦房结功能紊乱的动物模型具有重要价值。本文从动物选择、造模原理及方法、模型评价方法及检测指标等方面进行综述,希望能够为更加深入研究SSS致病机制提供基础和依据。

心房颤动伴长间歇的治疗策略:共识与争议

心房颤动(房颤)是心血管疾病中最为常见的心律失常,其常与病态窦房结综合征并存且相互作用。既往临床上对于有症状的房颤伴长间歇治疗多倾向于植入心脏起搏器联合抗心律失常药物,但近年来越来越多的研究表明,与植入起搏器相比,射频消融能降低房性心动过速相关心律失常的住院率、有效控制房颤,改善患者预后及心力衰竭住院率。但同时部分患者存在固有窦房结功能障碍(SND),且SND可在部分患有房颤的患者中逐渐进展及加重。因此,房颤伴长间歇患者的一线治疗策略仍存在争议。本文以房颤伴长间歇治疗策略的选择进行综述。

刘如秀从心肾论治病态窦房结综合征经验

病态窦房结综合征(sick sinus syndrome,SSS)是由窦房结起搏功能受损和或冲动传导功能障碍引发的一种难治性心律失常性疾病,主要表现为心动过缓、窦性停搏、慢快综合征、头晕、晕厥、乏力等症状。目前植入人工起搏器是SSS最有效治疗方式,但存在诸多不良反应及禁忌证,且不降低病死率。因此,寻求安全有效的治疗方式成为亟待解决的问题。刘如秀教授传承创新国医大师刘志明学术思想,提出从心肾论治SSS,采用温肾、通阳、活血等疗法,临床疗效显著。

心电瀑布图在快速识别病态窦房结综合征各种逸搏心律中的应用

目的探讨房性、室性、交界性逸搏心律的心电瀑布图特征,为快速分析病态窦房结综合征(sick sinus syndrome,SSS)等缓慢性心律失常的动态心电图奠定基础。方法选择合并有上述三种逸搏心律的SSS病例,在常规观察其心电散点图的基础上,进一步分析其心电瀑布图特征;结合心电瀑布图的逆向技术,分析和总结三种逸搏心律的心电瀑布图特征及其与相应心电图的对应关系。结果SSS患者在窦房阻滞或窦性停搏的背景下出现的这三种保护性逸搏心律(房性、室性、交界性逸搏心律)的频率接近,相互竞争、反复交替,其心电散点图、RR间期直方图等常用分析工具揭示的特征不明显,但各种心律的心电瀑布图却特征各异,为快速分析此类病例提供了捷径。正常窦性心律的R峰带水平居中,宽度小于120 ms,色谱代表QRS波群的高度;P峰带、T峰带平行分居于R峰带上下,宽度与色谱分别代表P波、T波的时限和极性。窦性心律的三峰带心电瀑布图宽度、色谱若有变化,则意味着节律变换,其中房性逸搏心律的心电瀑布图特征为P峰带变色,R峰带、T峰带正常;室性逸搏心律的心电瀑布图特征为P峰带消失,R峰带变宽变色、T峰带变色;交界性逸搏心律的心电瀑布图特征为P峰带消失,R峰带、T峰带正常。结论心电瀑布图可用于快速识别SSS患者中的各类逸搏心律,在心电大据分析中能弥补心电散点图及RR间期直方图的不足。
