[Effect of flecainide on longitudinal and transverse conduction velocities in ventricular myocardium. An experimental study].

2007

It is known that the effect of flecainide on longitudinal and transverse ventricular conduction velocities depends on the coupling interval. If this is so, whether the longitudinal or transverse direction is predominantly affected could depend on the magnitude of the coupling interval. In order to investigate this hypothesis, we studied the effect of flecainide, 1 micromol/L, on conduction velocities in excised heart preparations from 11 rabbits using a basal cycle length of 250 ms and inserting two extrastimuli at a decreasing coupling interval. Flecainide significantly reduced both conduction velocities. However, the effect increased as the coupling interval decreased for only the longitu…

013 Pre-infarction angina and cardiovascular complications in non ST segment elevation myocardial infarction: Data from the RICO survey

2010

BackgroundThe presence of preinfarction angina (PIA) has been shown to confer cardioprotection after ST segment elevation myocardial infarction (MI). However, the impact of PIA in non ST segment elevation (NSTEMI) remains to be determined.Patients and MethodsFrom the obseRvatoire des Infarctus de Côte d’Or (RICO) survey, 1541 consecutive patients admitted in intensive care unit with a first NSTEMI were included in the study. Patients who experienced chest pain 1) and 30-day mortality were collected.ResultsAmong the 1541 patients included in the study, 693 patients presented PIA. Baseline clinical characteristics were similar for the 2 groups. There was no significant difference for the GRAC…

Clinical Role of CA125 in Worsening Heart Failure

2020

Abstract Objectives The aim of this study was to evaluate the association between antigen carbohydrate 125 (CA125) and the risk of 1-year clinical outcomes in patients with worsening heart failure (HF). Background CA125 is a widely available biomarker that is up-regulated in patients with acute HF and has been postulated as a useful marker of congestion and risk stratification. Methods In a large multicenter cohort of patients with worsening HF, either in-hospital or in the outpatient setting, the independent associations between CA125 and 1-year death and the composite of death/HF readmission (adjusted for outcome-specific prognostic risk score [BIOSTAT risk score]) were determined by usin…

Management of complications after operations for acute pancreatitis.

1981

After early operation in 49 patients and delayed operation in 114 patients, all with acute hemorrhagic-necrotizing pancreatitis, 65% of patients developed local or general complications. Local complications were abscesses, peritonitis, bleeding, gastrointestinal fistulae or stenoses, and external pancreatic fistulae. Their cause can be traced to the large wound cavity with the tryptic wound surface as well as residual necrosis. The general postoperative complications were shock, acute renal failure, cardiorespiratory insufficiency, gastrointestinal bleeding, ileus, coagulopathy, and sepsis. These may have resulted from the local complications, or may even have been present before operation.…

How registers could enhance knowledge and characterization of genetic dyslipidaemias: The experience of the LIPIGEN in Italy and of other networks fo…

2020

Familial hypercholesterolemia (FH) is a common genetic disorder of lipid metabolism, still underdiagnosed and undertreated in the general population. Pathology registers could play a crucial role in the creation of a comprehensive and integrated global approach to cover all aspects of this disease. Systematic data collection of patients affected by FH has increased dramatically worldwide in the past few years. Moreover, results from registers already established for the longest time showed their potentialities in the implementation of the knowledge of FH, comparing country-specific approaches and providing real-world data about identification, management and treatment of FH individuals in t…

Prior oral conditions in patients undergoing heart valve surgery

2017

Background Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. Material and Methods A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups). A dental exploration was carried out, with calculation of the DMFT (decayed, missing and filled teeth) index and recording of the periodontal parameters (plaque index, gin…
