Cardiac risk stratification in elective non-cardiac surgery: Role of NT-proBNP

2011

AIM: The aim of the study was to investigate the utility of NT-proBNP measurement for the stratification of presurgical cardiac risk. METHODS: Cardiac risk before elective non-cardiac surgery was evaluated in 82 consecutive patients. From each patient a venous blood sample was drawn to determinate NT-proBNP levels. Patients were followed up over three months in order to detect the occurrence of cardiac adverse events. RESULTS: NT-proBNP was positively correlated (P<0.0001) with age, days of hospitalization (P=0.001) and ASA class (P=0.001). High surgical risk (P<0.0001), diabetes (P=0.004), dyslipidemia (P=0.006) and elevated levels of NT-proBNP (P<0.0001) were significantly correlated with…

Cardiorenal syndrome: the role of new biochemical markers

2012

Cardiorenal syndrome is a pathophysiological heart and kidney disorder, in which acute or chronic dysfunction of one organ induces a damage in the other. It's a syndrome more and more often encountered in clinical practice and this implies the need to recognize the syndrome through biochemical markers with a good sensitivity and specificity, since its earliest stages in order to optimize therapy. In addition to widely validated biomarkers, such as BNP, pro BNP, creatinine, GFR and cystatin C, other promising molecules are available, like NGAL (neutrophil gelatinase-associated lipocalin, KIM-1 (kidney injury molecule-1), MCP-1 (monocyte chemotactic peptide), Netrin-1, interleuchin 18 and NAG…

Left ventricular non compaction: epidemiology, clinical findings, diagnosis and therapy

2014

Abstract Left ventricular non compaction (LVNC) is a cardiomyopathy due to an arrest of the normal development of myocardium which determines the persistence of foetal myocardium in post--natal life in at least 2/3 of the wall (criterion known as non compacted/ compacted ratio greater than 2). Although in absence of a confirmed prevalence of LVNC, reviewing literature shows an increasing number of reports over the years, though diagnosed cases represent just the tip of a realistically far wider phenomenon. Clinical manifestations are variable, ranging from the absence of any symptom to congestive heart failure, arrhythmias and systemic thromboembolism. Echocardiography is the gold standard …

Rare cardiomyopathies: Diagnostic features

2013

Cardiomyopathies (CM) are an important and heterogeneous group of diseases affecting the myocardium. They can induce mechanical and/or electrical disorders and are due to a variety of causes, they frequently are genetic. However, since their high number and their clinical complexity, the identification is still a challenge. Echocardiography is a very useful tool in the assessment of CM. In this review we aim to define the typical clinical features and to discuss the main diagnostic tool, above all echocardiography that can help physicians in the correct assessment of CM.

Insulin resistance and acute coronary syndrome

2010

BACKGROUND: Insulin resistance (IR), which can be quantified by HOMA index (fasting glucose X fasting insulin/22.5), is considered the "primum movens" for the development of Metabolic Syndrome. Many authors have suggested that insulin resistance could raise both incidence and mortality of coronary heart disease (CHD). IR is also associated with important predictors of cardiovascular disease, as increased concentration of LDL or triglyceride, decreased concentration of HDL, high systolic blood pressure, visceral obesity. There is accumulating evidence that chronic sub-clinical inflammation, as measured by inflammatory markers as C-reactive protein (CRP) and fibrinogen, is related with insuli…

The long QT syndrome in pediatric age: Prognosis and risk factor

2008

AIM: Long QT syndrome is a rare arrhythmic disease with a low incidence in the general population. There are no sure clinical or electrocardiographic parameters that could lead to a correct prognostic stratification in patients affected by this syndrome. The correlation between the incidence of a sudden death or dangerous ventricular arrhythmias and the duration of QTc interval is still a controversial topic. METHODS: Twenty nine children affected by QT long syndrome were admitted to the Division of Pediatric Cardiology of the Casa del Sole Hospital of Palermo (Italy). Their diagnosis was made by electrocardiogram (ECG). The average age of the patients was 7.6 years. The average follow-up w…

Takotsubo cardiomyopathy after a positive emotional stress

2013

Takotsubo cardiomyopathy, also known as transient left ventricular apical ballooning syndrome, is a cardiac syndrome mimicking an acute coronary syndrome and characterized by peculiar transient left ventricular wall motion in the absence of significant coronary lesions at coronary angiography. The pathogenic mechanisms linking emotional stress to Takotsubo cardiomyopathy still remain undefined. The onset of Takotsubo cardiomyopathy can be triggered by an acute, intense emotional stress. This is the first report reporting that not only negative stress but also positive stressful event may precede the syndrome.

Is local stiffness, as measured by radio frequency, more sensitive than intima-media thickness?

2013

Aim: The aim of our study was to explore the changes in common carotid arterial intima-media thickness (CCA IMT) and local arterial stiffness to evaluate, non-invasively, early vascular disease in patients with cardiovascular (CV) risk factors and "normal" carotid IMT (6.05 m/s better identified, among patients with IMT <0.9mm, those with cardiovascular risk factors (sensitivity 82.0 % specificity 62.0 %; AUC 0.73). Conclusion. Increased stiffness is a result of change both in quantity and quality of the arterial wall. Arterial functional changes and distention alterations may herald the onset of vascular disease before manifestation of symptoms or detection of preclinical atherosclerotic l…
