Troponina e infarto periprocedurale: filo di Arianna o folle volo di Icaro?

2013

Percutaneous coronary interventions cause frequently an increase in myocardial necrosis markers. Is troponin elevation after percutaneous coronary intervention a predictor of events at follow-up or a consequence of the procedure with no cause-effect relationship with prognosis? The debate is still open

LEFT VENTRICULAR HYPERTROPHY IN HYPERTENSIVE PATIENTS WITH NORMAL ELECTROCARDIOGRAM

2011

Objective: In hypertensive patients the presence of left ventricular hypertrophy (LVH) is associated with increased cardiovascular (CV) morbidity and mortality. Unfortunately electrocardiogram (ECG) has a low sensitivity in detecting LVH, while echocardiography cannot be routinely and extensively performed in all hypertensive patients. In this study we evaluated the prevalence of LVH and of anomalies of diastolic function in a group of hypertensive patients with normal ECG, and free of diabetes and CV diseases. Design and Methods: Patients with CV diseases, diabetes, chronic kidney disease (CKD), electrocardiographic LVH (Sokolow-Lyons or Cornell criterion) or “strain” were excluded. We enr…

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…

ST segment elevations: Always a marker of acute myocardial infarction?

2013

AbstractChest pain is one of the chief presenting complaints among patients attending Emergency department. The diagnosis of acute myocardial infarction may be a challenge. Various tools such as anamnesis, blood sample (with evaluation of markers of myocardial necrosis), ultrasound techniques and coronary computed tomography could be useful. However, the interpretation of electrocardiograms of these patients may be a real concern. The earliest manifestations of myocardial ischemia typically interest T waves and ST segment. Despite the high sensitivity, ST segment deviation has however poor specificity since it may be observed in many other cardiac and non-cardiac conditions. Therefore, when…

Two-dimensional transthoracic echocardiographic normal reference ranges for proximal aorta dimensions: Results from the EACVI NORRE study

2017

International audience; AIMS: To report normal reference ranges for echocardiographic dimensions of the proximal aorta obtained in a large group of healthy volunteers recruited using state-of-the-art cardiac ultrasound equipment, considering different measurement conventions, and taking into account gender, age, and body size of individuals. METHODS AND RESULTS: A total of 704 (mean age: 46.0 ± 13.5 years) healthy volunteers (310 men and 394 women) were prospectively recruited from the collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. A comprehensive echocardiographic examination was obtained in all subjects following pre-defined protocols. Aortic…

Comparison between zofenopril and ramipril in combination with acetylsalicylic acid in patients with left ventricular systolic dysfunction after acut…

2012

Background: Angiotensin-converting enzyme inhibitors (ACEIs) are largely employed for treating patients with left ventricular dysfunction (LVD), but their efficacy may be negatively affected by concomitant administration of acetylsalicylic acid (ASA), with some difference among the different compounds. Hypothesis: The interaction between ASA and the two ACEIs zofenopril and ramipril may result in a different impact on survival of cardiac patients, due to differences in the pharmacological properties of the two ACEIs. Methods: This phase IIIb, randomized, double-blind, parallel-group, multicenter, European study compared the safety and efficacy of zofenopril (60 mg/day) and ramipril (10 mg/d…

Echocardiographic reference ranges for normal left ventricular 2D strain: results from the EACVI NORRE study

2017

International audience; Aims - To obtain the normal ranges for 2D echocardiographic (2DE) measurements of left ventricular (LV) strain from a large group of healthy volunteers accounting for age and gender. Methods and results - A total of 549 (mean age: 45.6 ± 13.3 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. 2DE data sets have been analysed with a vendor-independent software package allowing homogeneous measurements irrespective of the echocardiographic equipment used to acquire the data sets. The lowest expected values of LV strains and twist calculated as ± 1.96 standard deviations from the mean…

Echocardiographic reference ranges for normal cardiac chamber size: Results from the NORRE study

2014

AimsAvailability of normative reference values for cardiac chamber quantitation is a prerequisite for accurate clinical application of echocardiography. In this study, we report normal reference ranges for cardiac chambers size obtained in a large group of healthy volunteers accounting for gender and age. Echocardiographic data were acquired using state-of-the-art cardiac ultrasound equipment following chamber quantitation protocols approved by the European Association of Cardiovascular Imaging.MethodsA total of 734 (mean age: 45.8 ± 13.3 years) healthy volunteers (320 men and 414 women) were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORR…

Effects of ambient temperature, humidity, and other meteorological variables on hospital admissions for angina pectoris.

2012

Background: Seasonal peaks in cardiovascular disease incidence have been widely reported, suggesting weather has a role. Design The aim of our study was to determine the influence of climatic variables on angina pectoris hospital admissions. Methods: We correlated the daily number of angina cases admitted to a western Sicilian hospital over a period of 12 years and local weather conditions (temperature, humidity, wind force and direction, precipitation, sunny hours and atmospheric pressure) on a day-to-day basis. A total of 2459 consecutive patients were admitted over the period 1987–1998 (1562 men, 867 women; M/F – 1:8). Results: A seasonal variation was found with a noticeable winter pea…
