STUDY OBJECTIVES: Cardiac sympathetic nerve dysfunction is related to poor clinical outcome in patients with several different heart diseases. However, it is not clear whether cardiac sympathetic nerve activity is useful for predicting the onset of congestive heart failure (CHF) in patients with hypertrophic cardiomyopathy (HCM). The aim of this ...

BACKGROUND: Although ACE inhibitors are underprescribed for heart failure, factors associated with their use are not well described. Furthermore, the effectiveness of ACE inhibitors has been questioned in some populations, potentially contributing to underuse. Our objectives were to assess the correlates of ACE inhibitor use and the relationship between ACE ...

BACKGROUND: Mitral regurgitation (MR) may develop in patients with advanced systolic congestive heart failure (CHF) without organic mitral valve disease and contribute to worsening symptoms and survival. Surgical mitral annuloplasty improves symptoms in patients with advanced CHF, and percutaneous approaches to mitral annuloplasty are being developed. Our objective was to ...
Piccirillo Gianfranco - - 2004
A decreased LFP (low-frequency power) spectral component of HRV [HR (heart rate) variability] is a risk factor for sudden death in patients with CHF (chronic heart failure). In the present study, we evaluated factors (age, arterial pressures and HR) influencing LFP and HFP (high-frequency power) components in short-term recordings during ...

However, there is considerable disagreement about the ...
Beck da Silva Luís - - 2004
Heart failure (HF) is a public health problem with ever-growing costs. Signs such as jugular venous pressure and third heart sound have been associated with disease prognosis. Symptoms of heart failure are frequently subjective, and their real value is often overlooked. The authors aimed to assess the relationship between orthopnea ...
Smilde Tom D J - - 2004
BACKGROUND: Renal dysfunction is a strong predictor of mortality in chronic heart failure (CHF). Most patients with CHF have atherosclerotic vascular disease, and several authors have suggested that impaired renal function is only a marker of advanced atherosclerosis. We compared renal function in patients with ischemic and nonischemic CHF and ...

Heart failure is increasing in both North America and Europe. Although many similarities in the disease are apparent between the two continents, differences do exist. Heart failure with preserved systolic function appears to be increasingly important on both continents, and is associated more frequently with hypertension, aging, and female sex. ...

Traditional risk factors of a poor clinical outcome and mortality in the general population, including body mass index (BMI), serum cholesterol, and blood pressure (BP), are also found to relate to outcome in patients with chronic heart failure (CHF), but in an opposite direction. Obesity, hypercholesterolemia, and high values of ...

BACKGROUND: Epidemics of enterovirus 71 infection have caused the death of many children throughout the world. Rhombencephalitis, brain stem encephalitis, and heart failure were present in all of the fatal cases. However, no evidence of myocarditis was noted in the heart specimens, and the mechanism of heart failure remains unknown. ...

The COMET trial was a prospective, double-blind, randomised trial comparing carvedilol, a comprehensive adrenergic receptor antagonist, with metoprolol, a beta-1-selective agent in patients with heart failure and left ventricular systolic dysfunction. The trial showed a reduction in mortality with carvedilol that was consistent across subgroups. The purpose of this report ...
Miyamoto Shoichi - - 2004
BACKGROUND: It remains unclear whether circadian variation (CV) of cardiac autonomic nervous activity (CANA) is preserved in patients with chronic heart failure (CHF) as in healthy subjects. We have demonstrated that CANA in CHF patients is largely affected by patient recumbent position. METHODS: We studied eight mild to moderate CHF ...

BACKGROUND: While treatment with either angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs) is clearly superior to placebo in the treatment of heart failure patients, controversy still surrounds the effects of ARBs in patients already receiving an ACEi. Even more controversial is the wisdom of administering ARBs in patients ...

We devised our own method of evaluating a patient's general condition at admission, and estimated the usefulness of this method for evaluating patients with femoral neck fractures and its relationship to prognosis, in particular, factors influencing poor functional and vital prognoses. We examined 83 patients between January 1992 and March ...

Microvascular blood flow alterations may impair tissue oxygenation and may participate in the development of multiple organ failure in patients with severe heart failure. We hypothesized that microvascular blood flow alterations are present in patients with severe heart failure and cardiogenic shock. We used an orthogonal polarization spectral imaging technique ...

Beta-adrenergic receptor blockade is an established treatment of chronic heart failure (HF). Previous studies have suggested a potential pharmacogenetic interaction between beta-blocker therapy and the angiotensin-converting enzyme (ACE) I/D polymorphism in patients with HF. We designed this study to analyze changes in myocardial function of HF patients in response to ...

A number of large randomized, placebo-controlled mortality trials provided evidence-based data to guide the treatment of patients with systolic heart failure, but, with one exception, similar trials in patients with diastolic heart failure (DHF) either are not yet completed or have not been conducted at all. However, randomized outcomes trials ...

Heart failure is a common and costly medical condition. Ischemic heart disease and hypertension account for most cases of heart failure in developed countries. Estimates of the one-year mortality rates for patients with New York Heart Association (NYHA) Class II, III, and IV are 10%, 20%, and 40%, respectively. Angiotensin-converting ...

It has been reported that matrix metalloproteinase (MMP) protein concentration and activity are upregulated in the failing human heart. However, there are few reports describing the role of elevated level of circulating MMPs in congestive heart failure (CHF) patients. This study examined whether circulating matrix metalloproteinases (MMPs) are also related ...

Heart failure with normal systolic function has been equated to diastolic heart failure (DHF). DHF appears to be quite common in the elderly, especially in elderly women with hypertension. Recent epidemiologic studies suggest that 30%-50% of patients with heart failure may have DHF. Morbidity for DHF is considerable and comparable ...

It could be conjectured that the hemorheological disorders are involved in development of the ischemic heart disease. But this fact was so far insufficiently cleared up. The present studies were carried out in patients with various forms of chronic ischemic heart disease. We investigated the most significant factor of rheological ...

Beta-blockers have been shown incontrovertibly to improve morbidity and survival in patients with heart failure. However, there is limited information regarding their use in clinical practice settings, and reasonable utilization targets for quality improvement initiatives have not been established. We identified 500 consecutive patients with chronic heart failure seen at ...
