Evaluation of post-myocardial infarction regional and global left ventricular function by monoplane ventriculography: superiority of right versus lef…

1996

OBJECTIVES To study the significance of serial quantitative regional wall motion analysis, volumes, and ejection fraction findings as well as their prognostic implications derived from cineventriculography in 30 degrees right anterior oblique (RAO) projection in comparison with 60 degrees left anterior oblique (LAO) projection in post-myocardial infarction patients. Ventriculographic left ventricular parameters are accepted surrogates of mortality in myocardial infarction. Nowadays, in contrast to a biplanar approach in most institutions and clinical trials, the investigation is reduced to monoplanar ventriculography. However, it is not known whether the relevance of the two established pro…

Thrombolysis with saruplase versus streptokinase in acute myocardial infarction: five-year results of the PRIMI trial.

1999

Abstract Background Short-term safety and efficacy of thrombolysis with saruplase in acute myocardial infarction have been shown in several trials. To assess long-term outcome of patients treated with saruplase or streptokinase for myocardial infarction, a 5-year follow-up of patients included in the Pro-Urokinase in Myocardial Infarction Trial was performed. Methods and Results Follow-up data are available from 8 centers on 255 (92.4%) of 276 included patients. The 5-year mortality rate was comparable with 20.8% of patients in the saruplase group and 16.9% in the streptokinase group (odds ratio 1.29, 95% confidence interval 0.69 to 2.42). In both groups, a considerable number of fatal card…

Mean velocity of the pulmonary artery estimated by cardiac magnetic resonance as an early prognostic predictor in heart failure.

2018

Background and objective: To identify early, non-invasive prognostic indicators in heart failure (HF), with and without associated pulmonary hypertension, by means of cardiac magnetic resonance, and oxidative stress and anti-inflammatory biomarkers such as Trolox (TM) (antioxidant status) and IL-10 (anti-inflammatory cytokine). Patients and methods: We prospectively included 70 patients admitted for new-onset HF. During index admission, mean velocity of the pulmonary artery (mvPA) was measured, and blood Trolox (TM) and IL-10 determined. The study sample was divided in two groups according to the optimal cut-off value for event prediction calculated by the ROC curve (mvPA = 8 cm/s), conside…

Prognostic Value of White Blood Cell Count in Acute Myocardial Infarction: Long-Term Mortality

2005

Although traditionally an elevated white blood cell count (WBC), an indicator of systemic inflammation, has been accepted as part of the healing response following acute myocardial infarction (AMI), it has frequently been shown to be a predictor of adverse cardiovascular events. The present study was designed to assess the association between WBC and long-term mortality in AMI patients either with ST-segment elevation (STEMI) or without ST-segment elevation (non-STEMI). Patients and method. The study included 1118 consecutive patients who were admitted with the diagnosis of AMI: 569 non-STEMI and 549 STEMI. The WBC was measured in the 24 hours following admission. Patients were divided into…

2012

Aims To determine the role of assessing right ventricular (RV) function, using standard echocardiography and Doppler myocardial imaging (DMI), in the early diagnosis of cardiac amyloidosis and in the prediction of mortality. Methods and results Patients with primary systemic (AL) amyloidosis seen at our institution from 1 February 2004 through 31 October 2005 (N = 249) were categorized by left ventricular thickness and E′ velocity and compared with 38 age- and sex-matched controls. Standard echocardiographic and DMI examination were used to measure echocardiographic parameters of RV function: systolic tissue velocity, strain rate, and strain were determined for basal and middle RV free wall…

Normal-sodium diet compared with low-sodium diet in compensated congestive heart failure: is sodium an old enemy or a new friend?

2007

The aim of the present study was to evaluate the effects of a normal-sodium (120 mmol sodium) diet compared with a low-sodium diet (80 mmol sodium) on readmissions for CHF (congestive heart failure) during 180 days of follow-up in compensated patients with CHF. A total of 232 compensated CHF patients (88 female and 144 male; New York Heart Association class II–IV; 55–83 years of age, ejection fraction <35% and serum creatinine <2 mg/dl) were randomized into two groups: group 1 contained 118 patients (45 females and 73 males) receiving a normal-sodium diet plus oral furosemide [250–500 mg, b.i.d. (twice a day)]; and group 2 contained 114 patients (43 females and 71 males) recei…

Fibrosarcoma in pediatric patients: Results of the Italian Cooperative Group Studies (1979-1995)

2001

Background and Objectives Fibrosarcoma is a rare soft tissue sarcoma (STS) that has two peaks of incidence in pediatric patients: one in infants and young childern (infantile fibrosarcoma), another in older children (“adult type” fibrosarcoma). The purpose of this study was to describe the clinical features and the treatment results in patients affected by fibrosarcoma enrolled in two consecutive studies run by the STS-Italian Cooperative Group (ICG) between 1979 and 1995. Patients and Methods Twenty-five evaluable patients were grouped according the intergroup rhabdomyosarcoma staging (IRS) system: 12 Gr I, 5 Gr II, 8 Gr III. The cut-off point between the two forms was considered the age o…

Oral dabigatran versus enoxaparin for thromboprophylaxis after primary total hip arthroplasty (RE-NOVATE II)

2010

SummaryThis trial compared the efficacy and safety of oral dabigatran, a direct thrombin inhibitor, versus subcutaneous enoxaparin for extended thromboprophylaxis in patients undergoing total hip arthroplasty. A total of 2,055 patients were randomised to 28–35 days treatment with oral dabigatran, 220 mg once-daily, starting with a half-dose 1–4 hours after surgery, or subcutaneous enoxaparin 40 mg once-daily, starting the evening before surgery. The primary efficacy outcome was a composite of total venous thromboembolism [VTE] (venographic or symptomatic) and death from all-causes. The main secondary composite outcome was major VTE (proximal deep-vein thrombosis or non-fatal pulmonary embol…

Continuous ambulatory peritoneal dialysis and clinical outcomes in patients with refractory congestive heart failure.

2012

A B S T R A C T Introduction and objectives: Peritoneal dialysis has been proposed as a therapeutic alternative for patients with refractory congestive heart failure. The objective of this study was to assess its effect on long-term clinical outcomes in patients with advanced heart failure and renal dysfunction. Methods: A total of 62 patients with advanced heart failure (class III/IV), renal dysfunction (glomerular filtration<60 mL/min/1.73 m 2 ), persistent fluid congestion despite loop diuretic treatment and at least 2 previous hospitalizations for heart failure were invited to participate in a continuous ambulatory peritoneal dialysis program. Of these, 34 patients were excluded and adj…

2003

Background Diuretics have been accepted as first-line treatment in refractory congestive heart failure (CHF), but a lack of response to them is a frequent event. A randomized, single-blind study was performed to evaluate the effects of the combination of high-dose furosemide and small-volume hypertonic saline solution (HSS) infusion in the treatment of refractory New York Heart Association (NYHA) class IV CHF and a normosodic diet during follow-up. Materials and Methods One hundred seven patients (39 women and 68 men, age range 65-90 years) with refractory CHF (NYHA class IV) of different etiologies, who were unresponsive to high oral doses of furosemide, angiotensin-converting enzyme inhib…
