Changes in vitamin D and calcium metabolism markers in patients undergoing adjuvant chemotherapy for breast cancer.

Background: Changes in calcium metabolism and calcium urinary excretion during chemotherapy have not been thoroughly assessed in patients with early breast cancer (EBC), a population who frequently present vitamin D insufficiency. As hypercalciuria is a classical contra-indication to vitamin D (VD) supplementation, this study evaluated changes in VD and calcium metabolism parameters in patients with EBC undergoing adjuvant chemotherapy (CT).

Methods: In patients with EBC who received six cycles of adjuvant CT, VD and calcium parameters were monitored at inclusion, and then every 3 weeks, at each CT cycle initiation.

Incidence and Significance of Spontaneous ST Segment Re-elevation After Reperfused Anterior Acute Myocardial Infarction - Relationship With Infarct Size, Adverse Remodeling, and Events at 1 Year.

Background: Up to 25% of patients with ST elevation myocardial infarction (STEMI) have ST segment re-elevation after initial regression post-reperfusion and there are few data regarding its prognostic significance.

Methods and results: A standard 12-lead electrocardiogram (ECG) was recorded in 662 patients with anterior STEMI referred for primary percutaneous coronary intervention (PPCI). ECGs were recorded 60-90 min after PPCI and at discharge.

Cyclosporine before PCI in Patients with Acute Myocardial Infarction.

Background: Experimental and clinical evidence suggests that cyclosporine may attenuate reperfusion injury and reduce myocardial infarct size. We aimed to test whether cyclosporine would improve clinical outcomes and prevent adverse left ventricular remodeling.

Methods: In a multicenter, double-blind, randomized trial, we assigned 970 patients with an acute anterior ST-segment elevation myocardial infarction (STEMI) who were undergoing percutaneous coronary intervention (PCI) within 12 hours after symptom onset and who had complete occlusion of the culprit coronary artery to receive a bolus injection of cyclosporine (administered intravenously at a dose of 2.

Rationale and design of the Cyclosporine to ImpRove Clinical oUtcome in ST-elevation myocardial infarction patients (the CIRCUS trial).

Background: Both acute myocardial ischemia and reperfusion contribute to cardiomyocyte death in ST-elevation myocardial infarction (STEMI). The final infarct size is the principal determinant of subsequent clinical outcome in STEMI patients. In a proof-of-concept phase II trial, the administration of cyclosporine prior to primary percutaneous coronary intervention (PPCI) has been associated with a reduction of infarct size in STEMI patients.

[Renal denervation for resistant hypertension without general anesthesia: advantage of a MEOPA morphine protocol. Preliminary experience].

Unlabelled: Renal denervation using the technique of radiofrequency is used only recently for the treatment of resistant hypertension. Normally, it is done under general anesthesia because the ablation point technique is painful. We suggest an alternative to general anesthesia comprising an association of morphin 0.

[Coronary artery spasm during dobutamine stress echocardiography: prevalence, clinical and echocardiographic characteristics and prognosis].

Objectives: To assess the prevalence of coronary artery spasm during dobutamine stress chocardiography (DSE), to describe clinical and echocardiographic characteristics and prognosis.

Patients And Methods: We evaluated all the patients with known or suspected coronary artery disease (CAD) referred to our echocardiography laboratory for dobutamine stress test between January 2004 and June 2012, (10013 exams). Those with abnormal DSE underwent coronary angiograms with a systematic methylergometrine intracoronary injection in case of absence of significant coronary stenosis or spontaneous occlusive coronary spasm.

Coronary artery spasm and dobutamine stress echocardiography.

Aims: The aim of this article was to assess whether abnormal dobutamine stress echocardiography (DSE) can be due to a dobutamine-induced coronary spasm in patients with angiographically documented vasospastic coronary arteries.

Methods And Results: Between January 2004 and April 2008, we prospectively evaluated all patients with known or suspected coronary artery disease (CAD) referred to the echocardiography laboratory for dobutamine stress tests (6061 examinations). Those with abnormal DSE underwent coronary angiogram with a systematic methylergometrine intracoronary injection in the case of absence of significant coronary stenosis or spontaneous occlusive coronary spasm.

[Intravenous and oral propafenone in the treatment and prevention of paroxysmal atrial fibrillation].

The efficacy of propafenone in the treatment of paroxysmal atrial fibrillation was investigated in 16 patients presenting with frequent and/or poorly tolerated paroxysmal atrial fibrillation despite prophylactic treatment in 13 patients. Prolonged atrial fibrillation (> 10 minutes) was triggered in 16 patients following a standard atrial stimulation protocol. Intravenous injection of propafenone (2 mg/kg over 5 minutes) restored sinus rhythm in 12 patients (75%) within 15 minutes after the end of the injection.

[Comparative effects of anti-arrhythmia agents on ventricular refractory period and prevention of ventricular tachycardia induced by stimulation].

The efficacy of antiarrhythmic drugs is attributed to their actions on the refractory periods or conduction velocity in the reentry circuit. The aim of this study was to determine the relationship between these factors and the prevention of electrically inducible ventricular tachycardia (VT). Twenty-seven patients with sustained monomorphic postinfarction VT underwent programmed stimulation under basal conditions and after administration of oral Class I antiarrhythmic drugs.

[Value of systematic preventive antibiotherapy in cardiac pacemaker implantation].

The aim of this study was to assess the usefulness of prophylactic antibiotics during insertion of a cardiac pacemaker, in order to avoid infection of exteriorisation of infectious origin. The study involved two groups. One hundred and eight patients made up group I, a control group without the use of prophylactic antibiotics.

[Electrophysiologic evaluation and follow-up of patients with a syncopal episode of unknown origin].

The etiology of syncope of presumed cardiac origin can be determined by clinical and electrocardiographic examination with Holter monitoring in about 50 per cent of cases. The aim of this study was to review the data of electrophysiological investigation and the outcome of the patients in whom a cardiac pacemaker was eventually implanted, in those cases in whom the initial work-up had been negative. Ninety four patients, all of whom underwent standardised electrophysiological investigation, were included.

[Complex ventricular extrasystole. Value of programmed electric stimulation for evaluating the risk of sudden death].

A prospective study was carried out from May 1984 to July 1987 to determine the prognostic value of the results of programmed electrical stimulation (PES) in patients with complex ventricular ectopy. The study population comprised 118 patients, 80 with and 38 without apparent underlying cardiac disease. The PES consisted in at most 3 extrastimuli delivered to the right ventricular apex during 2 imposed basal rhythms.

[Post-traumatic fistula of the left anterior descending coronary artery and left ventricle. Apropos of a new case].

The authors report the case of a 23 year old man who presented with a continuous murmur five years after closed chest trauma. The electrocardiographic and echocardiographic findings indicated previous apical myocardial infarction. The underlying diagnosis was first suggested by continuous wave Doppler which showed systolo-diastolic flow in the septo-apical region directed towards the left ventricle (LV) in diastole.

[Cardioversion by internal electric shock of permanent atrial fibrillation].

A new technique for cardioversion of chronic atrial fibrillation was used in 17 patients whose arrhythmia had resisted all attempts at electrical and pharmacologycal cardioversion. Atrial fibrillation was badly tolerated by all patients despite digitalis administered alone (8 patients) or combined with amiodarone (9 patients). Twelve patients had left atrial dilatation at echocardiography.

[Septal rupture repaired in the acute stage of myocardial infarction. Clinical, hemodynamic and angio-coronarography findings in the evaluation of surgical risk].

Between 1977 and 1987, 27 consecutive patients (16 men, 11 women, mean age 66 years, range 54 to 75 years) with ventricular septal rupture complicating acute myocardial infarction underwent surgical repair. The purpose of this retrospective study was to analyse the post-operative mortality factors from clinical, haemodynamic and operative data in all patients and also from coronary angiographic data in 23/27 patients whose haemodynamic status allowed this type of exploration. Seventeen patients (63 p.

[Wolff-Parkinson-White syndrome. Outcome of patients treated with anti-arrhythmia agents from data of electrophysiological examinations].

Seventy-two consecutive patients with electrocardiographic evidence of Wolff-Parkinson-White syndrome underwent electrophysiological study (EPS). Fifty-five of these patients (76 p. 100) had episodes of tachycardia, 11 experienced palpitations or syncopes and 6 were asymptomatic.

Electrocardiographic characteristics of the escape rhythm in transient complete atrioventricular block induced by transcatheter electrical ablation of the atrioventricular junction.

The electrocardiographic characteristics of spontaneous escape rhythm during complete heart block induced by transcatheter ablation of the atrioventricular junction was prospectively studied in 21 patients by periodically interrupting temporary pacing. The data derived from 13 of these 21 patients, in whom conduction recurred after the procedure, were analyzed. An escape rhythm was present in 12 patients 8.

[Complex ventricular extrasystole. Value of technics of programmed electric stimulation].

The incidence and significance of ventricular arrhythmia induced by programmed electrical stimulation in subjects with complex ventricular ectopy were studied in 46 consecutive subjects: 34 with heart disease, 12 with an apparently normal heart. The procedure consisted of delivering on one spontaneous and 2 imposed rhythms one, two, then three extrastimuli. Significant arrhythmia with more than 6 ventricular complexes was induced in 17 patients (37%), including 6 (13%) with sustained ventricular tachycardia and 11 with unsustained ventricular tachycardia.

Electrophysiologic properties of falipamil (AQA-39)--a new bradycardiac agent.

Falipamil hydrochloride (AQA 39) is a new antiarrhythmic agent structurally related to verapamil. We evaluated the electrophysiologic properties of intravenous falipamil (1.5 mg kg-1 within 20 minutes) in 12 patients.

[Reduction of ventricular tachycardia by programmed electric stimulation. Clinical implications].

The mode of termination by programmed electrical stimulation of sustained ventricular tachycardia (VT) (more than 30 seconds) and induced by stimulation was investigated in 33 patients. In 27 patients (82%) programmed stimulation was possible because VT did not require an immediate electric shock or did not terminate spontaneously, but constant reduction of VT was obtained with one extrasystole in only 1 patient (3%), with two extrasystoles in 5 patients (15%) and by overdrive stimulation in 12 patients (36%). The remaining 15 patients (45%) required an external electric shock either because VT was poorly tolerated clinically, or because stimulation had failed.

Remote occurrence of high degree heart block following failure of transcatheter AV junctional ablation: incidence and clinical significance.

We report on two patients out of a series of 22 who underwent transcatheter ablation of the atrioventricular (AV) junction. The procedure failed to induce permanent complete heart block in 15 patients, 12 of whom were in sinus rhythm with 1:1 AV conduction before hospital discharge. Of the 12 patients, two (16.

[Intravenous sotalol in the acute treatment of supraventricular tachycardias].

The effects of intravenous sotalol (0.5 mg/kg in 6 minutes) were studied in 23 patients with supraventricular tachycardia (ventricular rate greater than 120 bpm) after failure of placebo (isotonic dextrose). Thirteen patients had atrial flutter or fibrillation and 10 a junctional tachycardia of recent onset.
