Brain natriuretic peptide and acute coronary syndrome.

The natriuretic peptide system (atrial natriuretic peptide, brain natriuretic peptide, BNP, and C natriuretic peptide) is an important marker of cardiac failure. These peptides are synthesized in atrial or ventricular myocytes in response to wall tension. In several studies the correlation between high BNP levels and mortality, in patients with acute coronary syndrome and heart failure, has been demonstrated. On the other hand, plasma levels of BNP could be considered as independent predictors of mortality in patients with heart failure. BNP could be used, for instance, as an early diagnostic marker for the differential diagnosis between cardiogenic and non cardiogenic dyspnea. In the Emergency Department its use will be important in the diagnosis of thoracic pain origin since it may help in the diagnostic and therapeutic course of this patient and to define the modality of hospitalization. Moreover, it can be used as a marker of heart failure severity and as an important negative prognostic factor. Some studies have confirmed that plasma BNP reflects the degree of left ventricular dysfunction and the prognostic significance after acute myocardial infarction and chronic heart failure.

Heart failure and therapy.

The clinical syndrome of heart failure is the final outcome of a number of diseases affecting the heart. Several studies undertaken over the past decade, have led to a significant change in the therapies available and a growing understanding of the physiopathological mechanisms. Increasingly, the current treatment of heart failure, is not just symptomatic but also etiologic and physiopathologic. In this paper we will try to furnish guidelines, as practical as possible, for the treatment of this syndrome, addressing the physiopathologic and experimental principles which underlie it. The present suggestions are based on the updated literature review, they conform to the latest guidelines of the European Society of Cardiology and are in agreement with the classification in grades, proposed by the American Heart Association and the American College of Cardiology.

Review of dilated cardiomyopathies. Dilated cardiomyopathies and altered prothrombotic state: a point of view of the literature.

Heart failure is an enormously important clinical problem that, if not faced, may overwhelm health care resources. Primary and secondary cardiomyopathies cause the majority of cases of clinical heart failure, which is thus better approached from the utility point of view of myocardial failure. Furthermore, the risk of thromboembolic complications presenting in such disease may be higher than in ischemic cardiomyopathy. Intracardiac thrombi and mural endocardial plaques (from the organization of thrombi) are present at necropsy in more than 50% of patients with dilated cardiomyopathy (DCM). Several studies have shown that systemic and pulmonary emboli are more frequent in patients with ventricular thrombi or plaques. Dilated cardiomyopathy has been associated with left ventricular thrombosis which leads to substantial morbidity and mortality as a site for peripheral emboli. There are some studies on patients with dilated cardiomyopathy showing altered hemostasis and platelet behavior despite sinus rhythm. Platelet activation, thrombin activation and fibrinolytic activity are increased in patients with DCM compared to normal subjects. However, these markers reflecting coagulation activation in patients with left ventricle thrombus are comparable to those in patients without thrombus in the left ventricle. The pathophysiology and clinical issues concerning the susceptibility to develop left ventricular (LV) thrombosis and its complications like cerebrovascular disease in patients with DCM are summarized and the most recent articles present in the medical literature are reviewed.
