Effects of long-term renal sympathetic denervation on heart failure after myocardial infarction in rats 总被引:1,自引:0,他引:1
The purpose of the present study was to investigate the effects of long-term renal denervation (RD) on heart failure due
to myocardial infarction (MI). Wistar rats were anesthetized and the bilateral renal nerves were surgically denervated 2 days
before MI was induced by coronary artery ligation. Four weeks later, left ventricular (LV) function and sodium excretion were
determined. In MI rats, RD improved the reduced sodium excretion. MI + RD rats revealed lower LV end-diastolic pressure and
greater maximum dP/dt as compared with those of MI+ innervation (INN) rats. LV end-diastolic and end-systolic dimensions were significantly smaller
and LV fractional shortening was greater in MI + RD rats than in MI + INN rats (20.9% ± 3.2% vs 14.9% ± 3.0%). In rats without
MI, RD did not affect either sodium excretion or LV function and dimensions. The present results suggest that the long-term
RD reduces LV filling pressure and improves LV function after MI, probably due to a restoration of impaired natriuresis. Increased
renal sympathetic nerve activity might contribute to the progression of heart failure after MI.

Atrial fibrillation impairs cardiac sympathetic response to baroreceptor unloading in congestive heart failure. 总被引:1,自引:0,他引:1
Paul A Gould Michael Yii Murray D Esler John M Power David M Kaye 《European heart journal》2005,26(23):2562-2567
AIMS: In this study, we investigated for a potential mechanism by which atrial fibrillation (AF) might convey a worse prognosis in congestive heart failure (CHF). Specifically, we aimed to determine whether AF impaired cardiac sympathetic response to baroreceptor unloading in comparison to sinus rhythm (SR) in CHF. METHODS AND RESULTS: Eighteen CHF patients (ejection fraction 30+/-2%, age 59+/- 2 years), nine in SR and nine in AF, were enrolled. A right heart study and cardiac sympathetic tone assessment by coronary sinus catheter were performed at baseline and after 10 min of 20 degrees and 30 degrees of passive head up tilt (HUT). Filling pressures fell significantly during HUT in both SR and AF groups (AF, P=0.002; SR, P<0.001). The cardiac sympathetic response to HUT was significantly attenuated by AF compared with SR (P=0.014). In conjunction, right atrial appendages were collected from 23 cardiac surgery patients, 12 in SR and 11 in AF to investigate the presence of fibrosis. AF was associated with a significant increase in the collagen density (P=0.025). CONCLUSION: AF is associated with impaired cardiac sympathetic response to baroreceptor unloading compared with SR in CHF, possibly secondary to atrial fibrosis. 相似文献

Diagnosing diastolic heart failure 总被引:2,自引:0,他引:2

BACKGROUND: increasing evidence supports the existence of left ventricular diastolic dysfunction as an important cause of congestive heart failure, present in up to 40% of heart failure patients. AIM: to review the pathophysiology of LV diastolic dysfunction and diastolic heart failure and the currently available methods to diagnose these disorders. RESULTS: for diagnosing LV diastolic dysfunction, invasive hemodynamic measurements are the gold standard. Additional exercise testing with assessment of LV volumes and pressures may be of help in detecting exercise-induced elevation of filling pressures because of diastolic dysfunction. However, echocardiography is obtained more easily, and will remain the most often used method for diagnosing diastolic heart failure in the coming years. MRI may provide noninvasive determination of LV three-dimensional motion during diastole, but data on correlation of MRI data with clinical findings are scant, and possibilities for widespread application are limited at this moment. CONCLUSIONS: in the forthcoming years, optimal diagnostic and therapeutic strategies for patients with primary diastolic heart failure have to be developed. Therefore, future heart failure trials should incorporate patients with diastolic heart failure, describing precise details of LV systolic and diastolic function in their study populations. 相似文献

The prevalence of left ventricular diastolic filling abnormalities in patients with suspected heart failure 总被引:3,自引:0,他引:3
Davie A. P.; Francis C. M.; Caruana L.; Sutherland G. R.; McMurray J. J. V. 《European heart journal》1997,18(6):981-984
AIMS: It is reported that one third of patients with heart failurehave normal left ventricular systolic function, and may or maynot have left ventricular diastolic dysfunction. We sought todefine the prevalence of left ventricular diastolic fillingabnormalities in a large unselected group of patients, unlikethe diagnosis by exclusion in the small highly selected groupsof patients studied previously. METHODS AND RESULT: Patients were referred by general practitioners to an open-accessechocardiography service for assessment of possible heart failure.Echocardiography included a Doppler study of transmitral flowat the tips of the mitral leaflets and calculation of an E/Aratio. Of 534 patients referred and assessed, 371 patients hadnormal systolic function and a measurable E/A ratio. These werecompared with age-adjusted reference ranges to give 9 abovethe reference range and 19 below. This is only 10 more thanwould be expected if our patients were normal. In the same groupof patients we found 96 cases of left ventricular systolic dysfunction,or 52 amongst the 423 with a measurable E/A ratio. CONCLUSIONS: Either left ventricular diastolic filling abnormalities arevery much less common than previously supposed or the E/A ratiois almost useless for their detection. 相似文献

Summary
Diastolic heart failure is a common clinical entity that is indistinguishable from systolic heart failure without direct evaluation of left ventricular function. Diastolic heart failure is a clinical diagnosis in patients with signs and symptoms of heart failure but with preserved left ventricular function and normal ejection fraction, and is often seen in patients with a long-standing history of hypertension or infiltrative cardiac diseases. In contrast, diastolic dysfunction represents a mechanical malfunction of the relaxation of the left ventricular chamber that is primarily diagnosed by two-dimensional transthoracic echocardiography and usually does not present clinically as heart failure. The abnormal relaxation is usually separated in different degrees, based on the severity of reduction in passive compliance and active myocardial relaxation. The question whether diastolic dysfunction ultimately will lead to diastolic heart failure is critically reviewed, based on data from the literature. Treatment recommendations for diastolic heart failure are primarily targeted at risk reduction and symptom relief. Currently, few data only are reported on diastolic dysfunction and its progression to systolic heart failure. 相似文献18.
