妊娠合并甲状腺功能亢进病人的护理 总被引:1,自引:0,他引:1
妊娠合并甲状腺功能亢进是产科常见的妊娠合并症,须引起产科工作者的重视.妊娠合并甲状腺功能亢进的孕妇,轻症或经过适当治疗病情得到控制者一般不影响妊娠,重症或不易控制病情的甲状腺功能亢进病人怀孕后母体和胎儿的合并症则较多.由于孕妇心脏负荷加大,重症甲状腺功能亢进病人易发生心力衰竭和甲状腺功能亢进危象.为此,对我院近10年妊娠合并甲状腺功能亢进病人的护理总结如下. 相似文献

The nature and prognosis of thyrotoxic heart disease 总被引:1,自引:0,他引:1
H Ikram 《The Quarterly journal of medicine》1985,54(213):19-28
Thirty-two patients with uncomplicated hyperthyroidism were compared to 17 patients deemed to be suffering from pure thyrotoxic cardiac failure, other heart disease having been excluded. The thyrotoxic failure group were older and had clinically and biochemically milder endocrinal abnormalities for a longer time. Haemodynamic studies at rest and exercise showed that the thyrotoxic failure patients had no functional cardiac reserve. Their response to propranolol indicated that myocardial function was dependent on beta-adrenergic activity. Following specific anti-thyroid medication cardiac function returned to normal in the majority of cases with cardiac failure. This study shows that hyperthyroidism by itself can cause a reversible cardiomyopathy. 相似文献

A previously fit 37-year-old woman was admitted with acute left ventricular failure, atrial fibrillation and a left-sided thromboembolic stroke. Her ventricular rate progressively increased despite full digitalisation. She had a cardiac arrest and was successfully resuscitated. Investigations revealed evidence of hyperthyroidism and she was treated for thyrotoxic crisis. She has made a complete recovery from the hemiparesis and is now in sinus rhythm. She denied any symptoms of hyperthyroidism. This patient had apathetic thyroid crisis, which is exceedingly rare in the young. 相似文献

Anemia is common in patients admitted to the cardiac intensive care unit. Many unique issues must be considered in the treatment of the anemic cardiac patient. Coronary artery disease and left ventricular dysfunction may significantly increase the risk of anemia. These patients have limited reserve because of a high extraction ratio of oxygen in the cardiac circulation. Left ventricular dysfunction increases the risk of complications from transfusion. Recent observational studies suggest that cardiac patients may benefit from a higher transfusion threshold. However, very few patients with cardiovascular disease have been included in clinical trials comparing high and low transfusion triggers. Experimental data and recent studies in humans suggest that cardiac patients may be intolerant of anemia. Pending definitive clinical trials in cardiac patients, we suggest a more aggressive transfusion trigger (9-10 g/dL) in patients with active cardiac disease. Pulmonary edema may be precipitated by transfusion in patients with left ventricular dysfunction. Large clinical trials are urgently needed to determine optimal transfusion thresholds in patients with cardiovascular disease. 相似文献

BACKGROUND AND PURPOSE: Cardiac performance can be characterized in terms of the relative duration of systole and diastole. In pediatric patients with dilated cardiomyopathy (DCM), a disproportionate shortening of left ventricular diastole was observed. The present study was intended to reproduce these findings in an adult patient group and to evaluate exercise-related changes of both time intervals. PATIENTS AND METHODS: Exercise radionuclide angiography was used in 61 patients with DCM NYHA (New York Heart Association) stage II-III. The phases of the cardiac cycle were derived from a radionuclide time-activity curve with high temporal resolution. The control group consisted of 26 patients referred for ventricular function assessment with radionuclide angiography before cardiotoxic cancer treatment. RESULTS: When the duration of systole was expressed as the product of systolic time and heart rate, DCM patients exhibited a significant increase in left ventricular systolic time at rest (23.9 vs. 21.5 s/min; p = 0.006) and during peak exercise (29.2 vs. 26.7 s/min; p = 0.01). The prolongation of left ventricular systole at peak exercise was evident, although the peak heart rate was significantly lower in the patient group than in the control group (118 vs. 127/min; p = 0.04). In DCM patients the diastolic time loss per beat was further quantified using a regression equation obtained from the healthy control group. A significant shortening of left ventricular diastolic time was confirmed during peak exercise. Furthermore, a progressive loss in diastolic time per beat from rest to peak exercise was noted. CONCLUSION: Cardiac cycle abnormalities of patients with DCM are characterized by a prolongation of left ventricular systole and an abnormal shortening of left ventricular diastole. The systolic-diastolic mismatch is accentuated during exercise and has the potential to impair the cardiac reserve in these patients by restricting ventricular filling and perfusion. 相似文献

Background Thyroid hormone has important effects on the cardiovascular system. The consequences of episodes of acute hypothyroidism on cardiac function have been investigated in only a few studies, and their results are inconclusive. Our objective was to investigate the effects of acute hypothyroidism on cardiac function in patients with iatrogenically induced subclinical hyperthyroidism after treatment for differentiated thyroid carcinoma. Material and methods Fourteen patients with a history of differentiated thyroid carcinoma on thyroid‐stimulating hormone (TSH)‐suppressive thyroxine replacement therapy were studied. We assessed cardiac function before, and 1 and 4 weeks after withdrawal of thyroxine substitution. We measured serum levels of free thyroxine, triiodothyronine and TSH and used a new sophisticated Doppler echocardiography technique, tissue Doppler imaging (TDI), to assess detailed and quantitative assessment of systolic and diastolic cardiac function. Echocardiographic parameters in patients were compared to controls. Results Compared to controls, patients had higher left ventricular mass and wall thickness and decreased diastolic function during TSH‐suppressive l ‐thyroxine substitution therapy. Thyroxine withdrawal resulted in a decrease in both early (E) and late (A) diastolic mitral inflow velocities, without impact on E/A ratio. Using TDI, late diastolic velocity (A′) decreased without impact on E′/A′ ratio. Left ventricular dimensions, wall thickness and mass did not change during thyroxine withdrawal. Conclusions Subclinical hyperthyroidism is accompanied by diastolic dysfunction. Subsequent acute hypothyroidism induces only subtle changes in diastolic function. 相似文献

Electrocardiograms of 67 thyrotoxic patients were studied. Subsequent electrocardiograms during euthyroidism in 16 patients permitted an analysis of voltage changes. Decreases in voltages after radioiodine therapy were significant (P less than 0.01) for the P wave in lead, V1, R wave in leads II, AVF, V4, V5, and V6, maximal RS wave, and maximal R wave and were present in all but one patient. Criteria for left ventricular hypertrophy (sum of S wave in V1 plus R wave in V5 or V6 greater than 35 mm), present in 21% of patients, regressed in all five patients who had later electrocardiograms during euthyroidism. Left ventricular hypertrophy or high-voltage R waves in the absence of usual causes may suggest the presence of hyperthyroidism. The concept that cardiac voltage is determined in part by thyroid hormone is reviewed; this relationship may be the basis for increased voltage in hyperthyroidism as well as decreased voltage in hypothyroidism. 相似文献
