甲狀腺功能影響心血管疾病患者心肌損害和遠(yuǎn)期預(yù)后的研究
[Abstract]:Background: Thyroid function affects myocardial damage and long-term prognosis in patients with acute myocardial infarction (AMI). It has been previously thought that the reduction of thyroid hormone levels in patients with severe illness is a feedback regulation of human self-protection. There is no evidence of thyroid function in patients with acute myocardial infarction (AMI). The purpose of this study was to assess the relationship between thyroid hormone levels and myocardial damage in patients with AMI, serum lipid levels after statin loading, and the effect of thyroid dysfunction on long-term prognosis in patients with AMI. From January 2010 to December 2012, 1 757 patients with acute myocardial infarction were enrolled in the study. 1112 patients were enrolled in the analysis set according to the exclusion criteria. The degree of myocardial damage was assessed by the highest value of CKMB positive cTnI, and logarithmic value was used to obtain normal distribution, which was expressed as log-CKMB and og-cTnI respectively. The primary endpoint was major adverse cardiac events (MACE) (including in-hospital all-cause death, myocardial infarction, and revascularization weight during hospitalization). Results: 1112 patients with AMI were divided into 5 groups according to their FT3 levels (1.79 pg/mL; 1.80-2.42 pg/mL; 2.43-2.67 pg/mL; 2.68-2.95 pg/mL; 2.96 pg/mL). A total of 222 patients (20%) had various types of thyroid dysfunction, and the most common type was low T3 syndrome (90 cases, 8.1%). Subclinical hyperthyroidism (73 cases, 6.6%) characterized by decreased TSH but normal T3 and T4, subclinical hypothyroidism (51 cases, 4.6%) and clinical hypothyroidism (8 cases, 0.7%) characterized by elevated TSH and normal T3 and T4, FT3 and log-CKMB (r =-0.251, P 0.001) and log-cTnI (r =-0.287, P 0.001) were significantly negatively correlated. In addition, there was a strong correlation between FT3 and high-sensitivity C-reactive protein (r = - 0.469, P 0.001). LVEF, as a cardiac function index, was positively correlated with FT3 (r = 0.191, P 0.001). Other thyroid hormones (FT4 and TSH) were not found to be correlated with the above indicators. There was a significant correlation between total cholesterol (moderate dose: Liner Coeff = - 0.105, P = 0.031; high dose: Liner Coeff = - 0.172, P = 0.029) and low density lipoprotein cholesterol (moderate dose: Liner Coeff = - 0.082, P = 0.001; high dose: Liner Coeff = - 0.113, P = 0.005). During the two-year follow-up, lower levels of FT3 (1.79 pg/mL (?) 1.80-2.42 pg/mL) were independent predictors of MACE (HR: 3.37, 95% CI: 1.66-6.85; HR: 2.28, 95% CI: 1.23-4.20). There was no statistically significant increase in the risk of death in patients with decreased SH (TSH 0.55IU/L) (HR: 1.545, 95% CI: 0.91-2.61). Conclusion: FT3 levels in patients with AMI were negatively correlated with myocardial damage markers and inflammatory markers, but positively correlated with cardiac function. Low FT3 and high TSH were independent risk factors for cardiovascular adverse events during long-term follow-up. The impact of thyroid function on cardiac function and long-term prognosis in patients with dilated cardiomyopathy Background: Abnormal thyroid hormone levels, which are common in heart failure, are affected. Extensive attention. Thyroid hormone levels are lower as heart failure progresses, and the prognosis of heart failure patients with low thyroid hormone levels is worse. In addition, previous studies focused on a certain thyroid function index, but did not explore the prognostic value of various types of thyroid dysfunction, so that different types of thyroid dysfunction in heart failure prognostic significance is controversial. Methods: This study was a prospective cohort study, the original cohort included in 2010. 532 patients with dilated cardiomyopathy hospitalized in Fuwai Hospital from January 2001 to October 2011 were screened by exclusion criteria, and 458 patients were followed up. The primary endpoint was all-cause death, defined as natural death from any cause. The secondary endpoint was cardiac death, defined as sudden death and death from heart failure. Death, death from malignant arrhythmias, and death from myocardial infarction. Kaplan-Meier diagram, univariate and multivariate Cox model were used to analyze the effect of FT3, TSH and thyroid function on prognosis. Results: According to thyroid function, 458 patients with dilated cardiomyopathy were divided into 6 groups, including hyperthyroidism. The highest incidence of thyroid dysfunction was subclinical hypothyroidism (n = 41, 9%), followed by subclinical hyperthyroidism (n = 35, 7%), hypothyroidism (n = 17, 4%) and clinical hypothyroidism (n = 12, 3%). There was no significant difference in fT4 between the two groups. The increase of log-TSH and the decrease of FT3 were independent predictors of deterioration of cardiac function. Stepwise method was used to screen those whose P value was less than 0.05 in univariate analysis and entered multivariate analysis. The results showed that og-TSH (HR: 2.189, 95% CI: 1.217-3.938), fT3 (HR: 0.483, 95% CI: 1.217-3.938), and fT3 (HR: 0.483, F3). 95% CI: 0.301-0.775) and renal insufficiency (HR: 2.045, 95% CI: 1.077-3.882) were independent predictors of deterioration of cardiac function. Low FT3 was a significant predictor of all-cause mortality (HR 3.18, 95% CI: 1.96-5.16, P 0.001; see Table 3). Elevated TSH was a strong predictor of death (HR: 2.828, 95% CI: 1.902-4.206), and decreased TSH had no significant effect on all-cause mortality. In multivariate analysis, the strongest predictors of all-cause mortality were clinical hypothyroidism (HR: 4.189, 95% CI: 2.118-8.283), followed by low T3 syndrome (HR: 3.147, 95% CI: 1.558-6.355) and subclinical hypothyroidism (HR: 2.869, 95% CI: 1.817-4.532). I:0.469-2.018). Conclusion: In patients with primary dilated cardiomyopathy, the decrease of FT3 and the increase of TSH levels are associated with the deterioration of cardiac function. Abnormal thyroid function (hypothyroidism, subclinical hypothyroidism, clinical hypothyroidism) is an independent risk factor for all-cause and cardiac death in patients with primary dilated cardiomyopathy. Background: Thyroid hormone levels are significantly associated with cardiac function in patients with heart failure, and are also an important risk factor for long-term adverse prognosis. At the animal level, there is insufficient evidence at the human level, leading to clinical consensus on the need for thyroid hormone therapy in these patients. The methods of single-photon emission computed tomography (SPECT) and positron emission tomography (PET) for evaluating myocardial perfusion/metabolism have also been widely used in clinic. Methods: 71 patients with primary dilated cardiomyopathy were enrolled in Fuwai Hospital from January 2010 to October 2011. Myocardial fibrosis was assessed by late gadolinium enhancement (LGE) and myocardium was assessed by 99mTc-MIBI SPECT. Myocardial perfusion was assessed by 18F-FDG PET imaging. Magnetic resonance imaging and radionuclide imaging were performed with 17-segment model. The myocardium was divided into 6 basal segments, 6 middle segments and 5 apical segments. LGE types were divided into three groups: no delayed enhancement, intermural enhancement (delayed enhancement in the myocardial wall, linear or patchy, not involving the whole myocardial layer) and transmural enhancement (delayed enhancement involving the whole myocardial layer). The primary endpoint was all-cause death, and the secondary endpoint was cardiac death. All patients were divided into four groups according to FT3 quadrant: Quartile 1 group (2.53 pg/mL, n=20); Quartile 2 group (2.53 pg/mL-2.76 pg/mL, n=16); Quartile 3 group (2.77 pg/mL-3.19 pg/mL, n=18); Quartile 4 group (> 3.19 pg/mL, n=17). From Quartile 1 to Quartile 4, the proportion of LGE segments decreased significantly with the increase of FT3 level. Potential (23.53%, 16.54%, 5.22%, 3.11%; P 0.001), the proportion of abnormal perfusion segments also showed a downward trend (20.88%, 16.54%, 14.05%, 9.69%; P 0.001). For abnormal metabolic segments, the incidence of Quartile 3 was significantly lower than that of Quartile 1 and Quartile 2 (8.82%, 7.35% vs 1.63%; P = 0.032). In logistic regression analysis, FT3 was the only risk factor for LGE enhancement (OR: 0.180, 95% CI: 0.059-0.550). For myocardial perfusion abnormalities, the OR value of FT3 in single-factor model was 0.38 (95% CI: 0.146-0.991) and in multivariate model was 0.172 (95% CI: 0.040-0.738). For myocardial metabolic abnormalities, FT3 was the only significant predictor in the multivariate model (OR: 0.338, 95% CI: 0.126-0.910). According to the presence of LGE enhancement and FT3 level (median 2.77 pg/mL), patients were divided into four groups: LGE negative + FT3 (> 2.77), LGE negative + FT32.77, LGE enhancement + FT3 (> 2.77), LGE enhancement + FT3 (> 2.77), LGE enhancement + FT3 (> 3.77), LGE enhancement + FT3 (%) 3 (> 2.77). 2.77. LGE enhancement + FT3 (> 2.77) (HR: 4.966, 1.851 - 8.658) and LGE enhancement + FT32.77 (HR: 8.623, 95% CI: 3.626 - 16.438) were independent risk factors for death. Conclusion: In patients with primary dilated cardiomyopathy, the decrease of FT3 level was significantly associated with the proportion of ventricular segmental fibrosis and abnormal myocardial perfusion / metabolism. Both are risk factors for long-term mortality in patients with primary dilated cardiomyopathy, and the combination of both can better predict the risk of death.
