AIMS: Subclinical diastolic dysfuntion in patients with preclinical heart failure with preserved ejection fraction (HFpEF) has been demonstrated in patients with Marfan syndrome (MFS). We investigated the relationship between diastolic dysfunction and NT-proBNP levels in patients with MFS. METHODS AND RESULTS: NT-proBNP, C-reactive protein (CRP) and diastolic function were assessed in 217 patients with MFS (31 ± 16 y, 110 f. and in 339 patients referred for suspected MFS in whom the diagnosis was ruled out according to the Ghent nosology (30 ± 15 y, 154 f)...

OBJECTIVE: To investigate the effect of recombinant human brain natriuretic peptide (rhBNP) on renal function in patients with acute heart failure (AHF) following acute myocardial infarction (AMI). METHODS: Consecutive patients with AHF following AMI were enrolled in this clinical trial. Eligible patients were randomly assigned to receive rhBNP (rhBNP group) or nitroglycerin (NIT group). Patients in the rhBNP group received rhBNP 0.15 μg /kg bolus injection after randomization followed by an adjusted-dose (0...

BACKGROUND: Ranolazine is a new anti-anginal drug that acts via late sodium current inhibition, and has been shown to improve diastolic dysfunction in isolated myocytes. Diastolic dysfuntion is common in patients with aortic stenosis (AS), and precedes symptom development and systolic dysfunction. The purpose of this study was to assess the effects of ranolazine on peak early diastolic strain rate (PEDSR) and exercise capacity in patients with AS. METHODS: Patients with asymptomatic moderate to severe AS and diastolic dysfunction underwent trans-thoracic echocardiography, exercise testing and cardiac magnetic resonance (CMR) imaging at baseline, 6 weeks after commencing ranolazine and at 10 weeks (4 weeks after discontinuation)...

Several experimental, pathological, epidemiological, and clinical studies have clearly depicted that diabetes mellitus results in cardiac functional and structural changes. Diabetic cardiomyopathy results in both structural and functional alterations in the myocardium. Several mechanisms have been implicated in the pathophysiology of diabetic cardiomyopathy. Of these, metabolic disturbances, myocardial fibrosis, small vessel disease, and cardiac autonomic neuropathy are the major players in the pathophysiology of diabetic cardiomyopathy...

OBJECTIVE: To explore the role of sympathetic nerve activity and vessel endothelial function in the pathogenesis of hypertension in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS: Based on polysomnography (PSG), blood pressure (BP) and disease history, 93 subjects were divided into four groups: OSAHS with hypertension (OH), OSAHS without hypertension (O), hypertension without OSAHS (H), normal control (N). In addition to the blood pressure measurement, blood samples were collected before and after sleep during the PSG testing night to measure norepinephrine, endothelin, and NO levels...

AIM OF THE STUDY: Heart failure is the final clinical presentation of a variety of cardiovascular diseases, such as coronary artery disease, hypertensive, toxic, and inflammatory heart disease. However, the cellular mechanisms responsible for the progressive deterioration of myocardial function observed in heart failure remain unclear and may result from cell death (programmed or not) and from an increase in number of nuclei and in the degree of their ploidy. METHODS: We examined thirty-eight explanted hearts obtained during transplantation for DNA content in the myocytic population...
