The correlation between thyroid function and the severity of coronary artery lesions / 中国介入心脏病学杂志

Obiective Tend to explore the correlation between thyroid function and the severity of coronary artery lesions in chinese coronary heart disease(CHD)patients. Methods A total of 558 patients who underwent coronary angiography at the cardiology department of Peking University First Hospital from January 2013 to June 2015 were enrolled in this retrospective study. All patients were divided into coronary heart disease group and non-coronary heart disease group. Thyroid hormone levels were tested in all patients before angiography,and clinical characteristics,lipid profiles and SYNTAX scores were also obtained. Results Of the 558 patients,409 were diagnosed of CHD(73.3％),and among them,5 patients were hyperthyroid/subclinical hyperthyroid(1.2％),13 patients were hypothyroid/subclinical hypothyroid(3.2％),14 patients had euthyroid sicknesssyndrome(ESS)(3.2％),377 patients were euthyroid(92.2％). Among the 149 non-CHD patients(26.7％),3 patients were subclinical hyperthyroid(2.0％),8 patients were hypothyroid/subclinical hypothyroid(5.4％),2 patients were ESS(1.3％),172 patients were euthyroid(91.3％). The proportion of patients with ESS in the CHD group was significantly higher than that of the non-CHD group (3.4％ vs. 1.3％,P=0.018). Except for the patients with ESS,FT3 level was significantly lower the in CHD group than that in the non-CHD group[(4.52±0.57)pmol/L vs.(4.65±0.63)pmol/L,P=0.015]. There were no significant differences in FT4,T3,T4 levels between the two groups(P>0.05). In the CHD group,there was an association between the SYNTAX score groups and free triiodothyronine(FT3)levels(F=6.260,P=0.002). A significant correlation was also observed between the FT3 level and the number of coronary artery lesions(F=5.691, P=0.004). There was no correlation between the SYNTAX score groups or number of coronary artery lesions and thyroid hormone levels,respectively. There were no correlations between lipid profiles and thyroid function. Patients were further divided into three subgroups according to their serum TSH levels. The prevalence of CHD is significantly higher in the subgroup with elevated TSH(85.7％)than in the subgroup with normal TSH(68.6％, P=0.022). Conclusions FT3 level is weakly associated with the severity of CHD. Higher TSH level may be a risk factor of CHD.

Cardiovascular events in patients with chronic kidney disease / 中华心血管病杂志

<p><b>OBJECTIVE</b>Cardiovascular event is common and is an important cause of death for patients with chronic kidney disease (CKD). The purpose of current study is to analyze the related risk factors of cardiovascular event in patients with CKD.</p><p><b>METHODS</b>Clinical data from 557 patients with CKD (stage III-V) who hospitalized in our hospital from Jan 2006 to Dec 2006 were retrospectively analyzed focusing on the risk factors of cardiovascular event and their impacts on death.</p><p><b>RESULTS</b>Among the 557 patients with CKD, 332 were male and 225 were female. There were totally 163 patients (163/557, 29.3%) suffered from cardiovascular events during hospitalization. The independent risk factors for cardiovascular event were age, history of coronary heart disease, anemia and fasting blood glucose level. The mortality was significantly higher in patients suffered from cardiovascular events than that in patients without cardiovascular events (9.82% vs. 2.28%, P<0.001).</p><p><b>CONCLUSIONS</b>For patients with CKD, anemia is another independent risk factor for cardiovascular events besides traditional risk factors and the mortality was significantly higher in CKD patients with cardiovascular events compared to CKD patients without cardiovascular events.</p>

The clinical features and outcomes of immunoglobulin light-chain amyloidosis with heart involvement / 中华心血管病杂志

<p><b>OBJECTIVE</b>To analyze the clinical features and outcomes of patients with immunoglobulin light-chain amyloidosis (AL) who had heart involvement.</p><p><b>METHODS</b>Clinical features and outcomes of AL amyloidosis patients with heart involvement in the past 7 years in our hospital were retrospectively analyzed.</p><p><b>RESULTS</b>Cardiac involvement was seen in 36 out of the 60 AL patients (60%). The clinical manifestations of cardiac amyloidosis included heart failure (50%), low QRS voltage (47.2%) and pseudomyocardial infarction (33.3%) in electrocardiography, as well as thickening of ventricular wall (63.9%), echo of granular sparkling texture (11.1%), atria dilation (33.3%) and diastolic dysfunction (30.6%) in echocardiography. The prognosis was poor, with a median survival time of 13.9 months.</p><p><b>CONCLUSION</b>Patients of AL amyloidosis with cardiac involvement are not rare. Thickening of ventricular wall and diastolic dysfunction are the most common characteristics. Special attention should be paid to this disease.</p>
