Filter by:Sudden death from ventricular arrhythmia is a serious and common complication of myocardial infarction, especially with low left ventricular ejection fraction (LVEF). Implantable cardiac defibrillator (ICD) implantation is currently recommended at three months of optimal medical treatment in patients who have had a myocardial infarction and have a LVEF below 35%. This strategy indeed allows a reduction in mortality while early post-infarction implantation showed no benefit in terms of survival. However, the risk of sudden death at this period is the greatest and the temporary defibrillator vest, marketed under the name LifeVest, is now indicated in the early post-infarction period in patients with LVEF less than 35%. Indeed, the LifeVest would allow a reduction in sudden death of rhythmic origin in the first three months post-infarction. No study has yet investigated the prognostic significance of a ventricular rhythm disorder (ventricular tachycardia [VT] or ventricular fibrillation [VF]) occurring during this early and short (approximately 3 months) particular period of wearing the LifeVest: is this a random event, or is it an event predictive of a rhythmic recurrence? The aim of the study is to assess the association between the occurrence of a sustained ventricular rhythm disorder in the early post-infarction period, during the period of wearing the LifeVest (ventricular episodes detected, treated or not), and the risk of rhythmic recurrence at 12 months.
PEACE study retrospectively evaluate patients who suffered an out-hospital cardiac arrest (OHCA) and who underwent a coronary angiography, enrolled in the registry of the Province of Pavia (Italy), Ticino Region (Switzerland), Wien region (Austria) and Nicosia area (Cyprus) to comprehend the best timing for post-ROSC ECG acquisition in order to reduce the number of false positive and to select the best candidates for emergency coronary angiography.
Precise identification of the infarct scar is essential for successful catheter ablation of ventricular arrhythmias in patients with chronic myocardial infarction. Voltage mapping of endocardial electrograms is currently used to delineate the necrotic scar but this is influenced by the direction of the activation wave front and is not sensitive enough to differentiate distinct degrees of transmural injury in the scar. Mapping of local myocardial electrical impedance may overcome these limitations.
During acute coronary syndrome, the American College of Cardiology and the American Heart Association recommend oxygen delivery to patients with less than 90% oxygen saturation. Oxygen therapy in these patients for a duration of at least 6 hours, but also stipulates that it is reasonable to administer oxygen to all acute coronary syndrome patients during the first six hours following the presentation. Hyperoxia also has well-established risks. Our research hypotheses are: (I) that current practices tend to use high oxygen flows resulting in high SpO2 levels during acute coronary syndrome. (II) there is a high rate of desaturation in patients with acute coronary syndrome and an automatic adaptation of oxygen flows may reduce this frequency. (III) that excessive oxygenation targets have no advantage. Our hypothesis is that maintaining a SpO2 of 90 to 94% is at least equivalent when compared to higher saturation objectives (SpO2 of 94 to 100%) with regard to the occurrence of complications in the patient in acute coronary syndrome . We will use two SpO2 targets with the FreeO2 system, 92 and 97%.
Multinational, multicentre, randomised, prospective, open, parallel group study directly comparing two glycoprotein-IIb/IIIa inhibitors, abciximab and eptifibatide, added early to standard treatment before primary PCI of STEMI patients with respect to effect on sum-ST-resolution after 60 minutes post-procedure and other measures of myocardial reperfusion
The purpose of this study was to develope and evaluate a new method for risk stratification which predicts high mortality risk in patients with cardiac disease based on simultateous examination of high resolution ECG, continuous arterial pressure and a breathing signal.
The purpose of this study is to investigate the performance of established and new risk preditors in predicting long term-mortality (up to ten years) of post-infarction patients.
