Introduction: Intravenous infusion therapy is a common and challenging invasive treatment procedure in hospital wards. Administration mistakes can have serious, even life-threatening, consequences. The Monidor solution was developed to help nurses administer gravity-based infusions and monitor them remotely, to avoid complications and reduce workload.

In this randomized prospective trial, we sought to compare early neointimal coverage of cobalt-chromium-based titanium-nitride-oxide-coated bioactive stents (CoCr-BAS) versus platinum-chromium everolimus-eluting stents (PtCr-EES) at 2-month follow-up in patients with acute coronary syndrome (ACS). Forty patients with ACS were randomized to receive either CoCr-BAS (n = 19) or PtCr-EES (n = 21).

Methods: The TITAX-AMI trial compared bioactive stents with paclitaxel-eluting stents in 425 patients with acute myocardial infarction. The BASE-ACS trial compared bioactive stents with everolimus-eluting stents in 827 patients with acute coronary syndrome.

Background: Atrial fibrillation (AF) is common in idiopathic dilated cardiomyopathy (IDC). We explored the clinical characteristics of IDC patients with chronic AF compared with those with sinus rhythm (SR).
Methods: A group of patients with IDC underwent extensive non-invasive and invasive evaluation during a hospitalization period.
Thrombocytopenia is often regarded as a risk factor for bleeding complications in patients undergoing percutaneous coronary intervention (PCI). The risk of mild to moderate baseline and acquired thrombocytopenia on bleeding and thrombotic or thromboembolic complications in patients with atrial fibrillation on oral anticoagulation therapy undergoing PCI, however, remains largely unknown. Management of Patients With Atrial Fibrillation undergoing Coronary Artery Stenting is a multicenter European prospective registry enrolling patients with atrial fibrillation undergoing PCI.

Methods: Thirteen patients with modest to severe CHF received three 24-h intravenous infusions of LS at 3-week intervals.

The objective of this study was to evaluate the possible benefits of coenzyme Q10 and selenium supplementation administered to patients with statin-associated myopathy (SAM). Sixty eligible patients entered the pilot study. Laboratory examination (CoQ10, selenium, creatin kinase) and intensity of SAM (visual scale) were performed at baseline, after 1 month, and at the end of study at month 3.

We sought to present the 5-year clinical outcome of the TITAX-AMI trial.
Methods: A total of 425 patients with acute MI were randomly assigned to receive either BAS (214), or PES (211).
Background: The TITAX-AMI trial demonstrated a better clinical outcome of titanium-nitride-oxide-coated bioactive stents (BAS) as compared with paclitaxel-eluting stents (PES) in patients with acute myocardial infarction (MI) undergoing early percutaneous coronary intervention (PCI). We explored the gender-based 3-year outcome of BAS as compared with PES in a subgroup analysis of the TITAX-AMI trial.
Methods: A total of 214 patients (52 women) with acute MI were randomly assigned to BAS, and 211 patients (54 women) to PES.
Background And Aims: The aim of this study was to evaluate the long-term effects of the titanium-nitride-oxide-coated (TITANOX) stent and the paclitaxel-eluting stent (PES) in patients who had undergone a percutaneous coronary intervention for acute myocardial infarction (MI).
Methods And Results: The TITAX-AMI trial randomly assigned 425 patients with MI to receive either a TITANOX stent or a PES. The primary end-point was a composite of MI, target lesion revascularization, or death from cardiac causes.
Background: Idiopathic dilated cardiomyopathy (IDC) is characterized by sympathetic nervous overactivity, inflammation and neurohumoral activation; however, their interrelationships are poorly understood.
Methods And Results: We studied 99 patients with IDC (age 54 +/- 1 years, left ventricular ejection fraction (EF) 40 +/- 1%, maximum oxygen uptake (VO(2)max) 20 +/- 1 ml kg(-1) min(-2), mean +/- SEM) by using (123)I-metaiodobenzylguanidine (MIBG) imaging. MIBG washout and MIBG heart/mediastinum (H/M)-ratio at 4 h postinjection were calculated.
Aims: The aim of this study was to evaluate the effectiveness of titanium-nitride-oxide (TITANOX)-coated stent and paclitaxel-eluting stent (PES) in patients presenting with acute myocardial infarction (MI).
Methods And Results: A total of 425 patients presenting with acute non-ST-elevation MI or ST-elevation MI were randomly assigned to receive TITANOX-coated stent or PES. The primary end point was a composite of MI, target lesion revascularisation (TLR) or death from cardiac causes.
Background: The appearance of circulating autoantibodies against cardiac troponin I (cTnAbs) in patients with heart failure has been reported. We sought to evaluate the role of circulating cardiac troponin I (cTnI) and cTnAbs in the pathophysiology and prognosis of idiopathic dilated cardiomyopathy.
Methods And Results: Circulating concentrations of cTnI and the presence of cTnAbs were determined in 95 patients with idiopathic dilated cardiomyopathy.
Background: Dilated cardiomyopathy (DCM) is associated with myocardial fibrosis, and proinflammatory cytokines may play a role in this.
Methods: N-terminal type I and III procollagen propeptides (PINP, PIIINP) and cross-linked telopeptide of type I collagen (ICTP) were measured from serum samples of 73 patients with DCM and 56 age and sex matched controls. Circulating cytokine levels were determined in DCM patients.
Apelin is a recently discovered peptide ligand reported to be involved in the regulation of cardiovascular homeostasis. The exact role of apelin in the pathophysiology of congestive heart failure has remained obscure, and the reported circulating levels of apelin in patients with heart failure have been contradictory. To establish the role of apelin in the assessment of cardiac dysfunction we measured plasma apelin levels in 65 patients with congestive heart failure caused by idiopathic dilated cardiomyopathy (IDC) and 14 healthy volunteers by specific radioimmunoassay.
View Article and Find Full Text PDFHRV and HRT are independent predictors of cardiovascular mortality. Aging reduces HRV, but results from the physical exercise trials are controversial. The primary aim was to study changes in heart rate variability (HRV) and heart rate turbulence (HRT) in a six-year controlled randomized trial at regular low to moderate intensity physical exercise.
View Article and Find Full Text PDFDecreased heart rate variability (HRV) and heart rate turbulence (HRT) are independent predictors of mortality after acute myocardial infarction (AMI). There are no previous studies on the relationship between warm-up phenomenon and cardiac autonomic control in stable coronary artery disease (CAD). We investigated the responses in HRV to repeated exercise induced ischemia and differences in global HRV and HRT in patients with and without adaptation to ischemia (warm-up phenomenon).
View Article and Find Full Text PDFBackground: Dilated cardiomyopathy (DCM) is familial in approximately 20-35% of cases of idiopathic DCM. Several mutations in the different sarcomere protein genes have been reported to cause DCM.
Aims: We wanted to investigate the role of sarcomere protein gene variants in Finnish DCM patients.
Aims: The mutations most frequently associated with dilated cardiomyopathy (DCM) have been reported in the lamin A/C gene. The role of variants of the lamin A/C gene was investigated in patients with DCM from eastern and southern Finland.
Methods And Results: All 12 exons of the lamin A/C gene were screened in 18 well-characterised familial DCM patients from eastern and southern Finland and in 72 sporadic DCM patients from eastern Finland using the PCR-SSCP method.
Approximately 20-35% of cases of idiopathic dilated cardiomyopathy are familial. DCM-associated mutations have been reported in 13 genes including the desmin, delta-sarcoglycan, and metavinculin genes. This study screened for variants in these genes in Finnish patients with DCM.
View Article and Find Full Text PDFBackground: The warm-up phenomenon, that is, attenuation of myocardial ischemia during repeated physical exercise, has been demonstrated in numerous studies. However, its duration and underlying factors have not been properly studied in patients with coronary artery disease.
Methods: Fifty-two patients with stable angina pectoris and previous positive stress testing underwent cardiac catheterization and 2 successive exercise tests randomly separated by resting periods of 15, 30, 60, or 120 minutes (groups 1-4).
