In the present study, no echocardiographic measures of diastolic function were obtained and therefore it is not possible to determine if isolated LV diastolic dysfunction can account for the higher proportion of apparent non-systolic heart failure in the obese patients with normal ejection fraction.

For this reason, risk ratios for death in the different BMI groups, which sigb been controlled for the impact of covariates described above, are presented with respect to the presence or absence of chronic obstructive pulmonary disease and the presence or absence of LV systolic dysfunction Table 2. The ventricles may stretch to the point that the heart can't pump enough blood through the body. The decreased arterial-venous oxygen gradient triggers the activation of neurohormonal reactions to compensate for the decreased oxygen and blood supply. Obesity leads to an increase in total blood volume, stroke volume, and cardiac output; nonetheless, it is correlated with a reduction in systemic vascular resistance.

In line with this, our study suggests that the congestige of BMI on survival is complex, implying that a major part of the effect of BMI on mortality is due to a high risk in cachexic patients, and also that the effect of overweight and obesity at least to some extent may be attributed to confounding by LV systolic function and chronic obstructive pulmonary disease. Consequently, results obtained in epidemiological studies restricted to patients with LV systolic dysfunction cannot readily be extrapolated to the general CHF population. Issue Section:.

The trial showed herat significant effect of dofetilide when compared with placebo. In addition, various favorable cardiovascular effects of weight reduction have been seen in obese non-HF individuals, including decreased left ventricular mass, decreased ventricular filling pressures and mean arterial pressure, and improvement in several systolic and diastolic parameters. It has been suggested that leptin actions may control obesity by modulating food intake, inhibiting adipogenesis, and triggering lipolysis.

Using BMI as a common measure of obesity and neglecting more accurate tools is another defect in studies suggested by some authorities. External link. Eur J Heart Fail. However, it seems well documented that a paradoxical positive correlation between BMI and survival is present at least in some groups of CHF patients.

How this guideline was developed

It is logically assumed that obesity leads to an increase in cpngestive incidence and prevalence of heart failure HF. This happens if the heart muscle becomes stiff from conditions such as high blood pressure. Furthermore, left atrial enlargement is frequently seen in consequence of not only an increase in blood volume but also changes in LV diastolic filling.

As expected, the proportion of echocardiograms that could be evaluated was lower among overweight and obese patients, reflecting the technical difficulties associated with cardiac ultrasound imaging in large subjects.

Although intentional weight loss in obese congeshive without HF has been a subject of several studies in preventive cardiology, 12 there have not been any large long-term trials to specifically address effects of intentional weight loss in obese patients with HF. Further studies are needed to elucidate the mechanism for this relationship between obesity and improved HF prognosis further. Several prognostic factors, such as serum cholesterol, peak oxygen consumption, serum sodium and natriuretic peptides were not measured in the DIAMOND registry and this, of course, is a limitation of the results obtained in the multi-variable analyses.
