Abstract
Abstract
Background
PCSK9i on top of high intensity statins have shown clinical benefit in patients after Acute Myocardial Infarction (AMI) who are not at LDL-c target. The ESC Task Force has defined guidance for the prescription of PCSK9i. Among patients discharged after AMI, the rate of those eligible for PCSCK9i is poorly documented.
Methods
We used data from the nationwide French FAST-MI 2015 registry. PSCK9-eligible patients were defined as those discharged with high intensity statins with expected-LDL>140 mg/dL, or >100mg/dL if they had additional high risk features such as diabetes with renal dysfunction or hypertension, multivessel coronary disease, associated peripheral artery disease or recurrent MI. The expected LDL-c was estimated from admission LDL-c and changes in lipid-lowering treatment. The rate of eligible patients was estimated from actual treatment and optimized treatment (i.e. addition of ezetimibe).
Results
Among 5291 pts included, 4715 (89%) were discharged with statins, at high intensity in 3655 (71%). Expected LDL was 71mg/dL (IQ 56, 95). Among patients discharged with high intensity statins, 3146 (59%) had an expected LDL-c<100/mg (figure, in green). PCSK9-eligible patients were those with LDL-c>140mg/dL (n=178, 3.3%, in red) and, among those with LDL-c 100–140mg/dL (n=331, 6.2%, in yellow), patients who had additional risk features (n=227 (4%)). As a result, the population eligible for PSCK9i according to the ESC guidance would represent 7.6% (405 pts) of the population admitted with AMI. Expanding the indication to patients with statins, but not at high intensity would add 159 (3%). Conversely, optimizing discharge treatment with ezetimibe would reduce the rate of eligible patients to 3% (181 pts, in brown).
Conclusions
In real life, according to the ESC Task Force, 7.6% of the whole population admitted for AMI would be eligible for PCK9i. This rate could be reduced to 3% with the addition of ezetimibe.

Abstract
The acute hemodynamic effects of 20 mg iv amlodipine were evaluated in a placebo-controlled study in 16 normotensive patients 15 +/- 1 days after an acute myocardial infarction by covariance analysis. Atenolol was given orally for at least 1 week before the study to maintain the heart rate between 50 and 60 beats/min. All patients were given two doses of 10 mg of amlodipine, or 10 ml of a placebo twice, in i.v. infusion lasting 2 minutes each. Hemodynamic data were collected during the control period and 15 minutes after each of the two amlodipine or placebo infusions. At the time of the last measurements, 15 minutes after the second amlodipine or placebo infusion, the plasma amlodipine level was 31 +/- 16 micrograms/l and the plasma atenolol level was 773 +/- 564 mu/l in the amlodipine group versus 795 +/- 916 micrograms/l in the placebo group. There were no chronotropic, dromotropic, or inotropic effects. The main hemodynamic effect was a fall in systemic vascular resistance (1548 +/- 591 dynes.sec.cm-5 to 1176 +/- 526 dynes.sec.cm-5, p = 0.045) with decreases in aortic pressure and in the left ventricular stroke work index. The left ventricular ejection fraction was 51 +/- 12% in the placebo group and 56 +/- 15% in the amlodipine group (ns) during the control period, and did not change after infusion of placebo or amlodipine. Left ventricular compliance seemed to be enhanced by amlodipine, because the end-diastolic left ventricular volume index rose from 82 +/- 11 ml/m2 to 87 +/- 11 ml/m2 (p = 0.026) 15 minutes after the beginning of the second infusion of 10 mg of amlodipine, without any change in end-diastolic left ventricular pressure. Intravenous infusion of 20 mg of amlodipine is well tolerated 15 days after acute myocardial infarction in normotensive patients without deeply depressed left ventricular systolic function and chronically treated with atenolol. The main hemodynamic effects observed are potentially useful for such patients.

Abstract
This multicentre, randomized, double-blind study, conducted in parallel groups, was designed to compare the efficacy and safety of cibenzoline (C) and oral propafenone (P) in the prevention of recurrent atrial arrhythmias (M) over a 6-month period. Patients of either sex with reduced atrial fibrillation or flutter and predominantly in sinus rhythm (> 50%), with a left ventricular shortening fraction greater than or equal to 20% and not receiving any antiarrhythmic treatment were included. Patients presenting severe conduction disorders, severe heart failure (NYHA class III or IV), marked hypotension or recent myocardial infarction were not included. Treatments were administered at the dosage of one tablet twice a day, i.e. 260 mg/day of cibenzoline or 600 mg/day of propafenone. This dosage was reduced by one half in elderly patients (> 70 years). Patients were seen on inclusion (Dzero), and at the third and sixth months or in the case of recurrence of symptoms. Recurrent arrhythmias were assessed by ECG and 24-hour Holter monitoring and according to the symptoms experienced by the patients. Sixty-five patients, 36 men and 29 women, between the ages of 34 to 86 years and presenting an atrial arrhythmia-atrial fibrillation (80%) or atrial flutter (20%)-were included in the trial: 34 patients received cibenzoline and 31 received propafenone. The arrhythmia had already been treated in 78% of cases. Its aetiology was related to hypertensive heart disease (32%), valvular heart disease (8%), other (17%) or idiopathic (43%). The arrhythmia was symptomatic in 91% of patients on inclusion. The ultrasonographic left ventricular shortening fraction was 32.8 +/- 8.1% in group C and 32.6 +/- 6.4% in group P. The two groups were comparable before treatment. The efficacy of the two treatments was comparable: no significant difference in the number of recurrences was demonstrated: 11 patients treated with C and 12 patients treated with P; cumulative percentages of patients without recurrence with good tolerance of treatment (Kaplan-Meier acturial curves) at 6 months were 55.9% with C and 48.4% with P(NS); probability of no recurrence at 6 months (0.63 +/- 0.09 in group C and 0.57 +/- 0.09 in group P); mean time to recurrence (53.4 +/- 44.3 days in group C and 61.6 +/- 35.3 days in group P). Adverse events leading to discontinuation of treatment occurred in 4 patients from each group, and one proarrhythmic effect at 6 months in a patient in group P. The treatments were well tolerated in the majority of cases: there was no significant difference in the number of patients presenting at least one adverse event: 9(26.5%) in group C, 11(35.5%) in group P. Most events were considered to be mild or moderate. The effects of the two treatments on the course of blood pressure, heart rate, PR interval and QT interval calculated at 3 and 6 months compared to DO were not statistically different. The QRS interval increased to a significantly greater extent in group C that in group P (p = 0.02 at 3 months; p = 0.0005 at 6 months). No significant difference was observed between the two groups for the course of laboratory parameters at 3 and 6 months compared to DO in the patients present at these three visits. Cibenzoline can therefore constitute a good alternative to propafenone in the prevention of symptomatic recurrences of atrial tachyarrhythmias. The preferential use of one or other treatment can be guided by individual factors, including tolerance.

Abstract
83 patients were enrolled in a multicentre, randomized, open study to assess the efficacy of amlodipine in stable effort angina. Preselected patients were submitted to a one-week placebo wash-out period during which only nitrates or molsidomine were authorized. Patients were then randomized to receive either 5 mg of amlodipine as a morning dose, or 180 mg of diltiazem in three divided doses. After two weeks, the dosage was able to be increased (according to clinical efficacy) to 10 mg of amlodipine as a single dose or 240 mg of diltiazem in four divided doses. The antianginal efficacy of these two treatments was essentially evaluated in terms of the results of stress tests (ST) conducted at the end of the second week and fourth week of active treatment: and 24 hours after the last dose of the drug. The results of 63 patients who scrupulously complied with the protocol showed that amlodipine and diltiazem corrected or improved the ST parameters (time to onset and amplitude of ST depression, duration of ST, work performed). The anti-ischaemic action of amlodipine was maintained for at least 24 hours after the last dose and therefore provides better security (by covering the entire 24-hour period) and better compliance (by tolerating a dose omission of several hours).

Abstract
This retrospective study was designed to determine the characteristics of myocardial infarction with normal coronary arteries. The files of consecutive patients admitted to hospital for a first infarction in 1992 and 1993 were analysed. Patients younger than 70 years of age, who had undergone coronary angiography during their admission to hospital were selected. A total of 109 infarctions complied with these criteria and 9 of them were associated with angiographically normal coronary arteries. In this series, patients with angiographically normal coronaries tended to be younger than those with at least one stenotic coronary artery (47 +/- 13 years vs 55 +/- 11 years, p = 0.07). The sex ratio did not differ between the two groups. The body mass index of patients with normal coronary arteries was significantly lower (22.9 +/- 3.9 kg/m2 vs 26.3 +/- 3 kg/m2; p = 0.02). These patients more frequently reported a history of phlebitis (3/9 kg/cm2 vs 26.3 +/- 3 kg/cm2; p = 0.02). These patients more frequently reported a history of phlebitis (3/9 vs 2/100). The frequency of anterior and posterior infarctions was virtually the same. Myocardial infarction with normal coronary arteries appears to be less severe, as reflected by the creatine phosphokinase peak (867 +/- 268 IU/l vs 1921 +/- 1389 IU/l), the maximal sum of ST elevation (5 mm vs 16 +/- 12 mm; p = 0.05), the percentage of left ventricular akinesia on angiography (25.5 +/- 4 vs 38.7 +/- 11.8; p = 0.01), and the lower ventricular end-diastolic pressure (11.5 +/- 3.5 mmHg vs 38.7 +/- 11.8 mmHg; p = 0.02). Fewer complications were observed during the acute phase, with no deaths. During the subsequent follow-up, with a median of 2 years, no recurrent infarctions, no cardiac decompensation and no deaths were observed in the group with normal coronary arteries. Two patients presented an episode of angina and one developed a recurrent episode of phlebitis. In the other group of 100 patients, 12 deaths were observed during the acute period, followed subsequently by 2 other deaths, 10 episodes of recurrent angina, 2 recurrent infarctions and 12% of patients developed heart failure. In this series, infarction with normal coronary arteries therefore appears to have a good prognosis, possibly because of more limited myocardial necrosis. No abnormalities of haemostasis or coagulation were observed in these patients.

Abstract
The objective of this study was to compare the efficacy and safety of cibenzoline (130 mg twice a day) and sustained-release hydroquinidine (300 mg twice a day) in the prevention of recurrent atrial fibrillation (AF). This randomized double-blind study was conducted in 87 patients, with a mean age of 62 years, presenting with a history of AF for 72 hours to a maximum of 3 years. After restoration of sinus rhythm, in order for the subjects to be included in the study, echocardiography had to reveal a left ventricular shortening fraction of more than 20%. Patients were followed for one year by clinical examination, ECG and 24-hour Holter monitoring performed 7 days after inclusion, then after 3, 6, 9 and 12 months. The two groups, treated with either cibenzoline (n = 40) or hydroquinidine (n = 44), were comparable. The AF recurrence rates with cibenzoline or hydroquinidine were 34.9% had 36.4% at 6 months, and 41.9% and 43.2% at 12 months, respectively (NS). Most recurrences occurred during the first month. Adverse effects were reported in 10 patients (23.3%) with cibenzoline and 12 patients (27.3%) with hydroquinidine. They led to discontinuation of treatment in 6 patients (14%) treated with cibenzoline and 5 patients (11.4%) treated with hydroquinidine. Serious adverse events included one death from hypoglycaemic coma and one case of persistent ventricular tachycardia with hydroquinidine. In conclusion, oral cibenzoline demonstrated the same antiarrhythmic activity as hydroquinidine in the long-term prevention of recurrent atrial fibrillation, with a similar degree of safety. This drug can therefore constitute an alternative to conventional antiarrhythmics in this context.

Abstract
Few cases of transcatheter coronary fistula closure have been reported. High flow coronary fistulae are usually treated by surgery. This case report presents a 5.4 liters/min flow coronary fistula percutaneously closed by steel coils. This large flow needed the packing of 25 coils, 10-15 cm long, for its total occlusion.

Abstract
This study assesses the value of P wave measurements on the surface ECG at implantation, in the prediction of atrial fibrillation in VVI paced patients. From a consecutive series of 320 pacemaker implantations 172 VVI paced patients for symptomatic atrioventricular block (AVB) (n = 126; mean age 69 +/- 14) or sick sinus syndrome (SSS) (n = 56; mean age 68.6 +/- 12) and in sinus rhythm at implantation were used in this study. P wave duration in V1 is correlated with the incidence of atrial fibrillation during 5 years of follow-up. V1 at implantation was significantly longer (114.6 +/- 2.7 msec) in the patients who developed atrial fibrillation than in those who did not (91.9 +/- 2.7 msec) (P < 0.001). Although positive predictive accuracy increases progressively for higher V1 values for AVB and SSS, the negative predictive and diagnostic accuracy of V1 criteria were less in SSS. Application of the Bayes' theorem showed that in SSS the probability to develop atrial fibrillation is 33% for V1 < 110 msec and is for V1 < 90 msec still higher than that reported in DDD paced patients. In the AVB group the probability to develop atrial fibrillation is 8% for V1 < 110 msec and 6% for V1 < 100 msec. It seems, therefore, that atrial stimulation (AAI or DDD) is always indicated in SSS. In AVB with V1 < 100 msec, DDD pacing, if not needed for other indications, apparently does not offer much benefit in the prophylaxis of atrial fibrillation.

Abstract
The P waves of patients with VVI pacemakers were compared with those of DDD pacemakers at implantation and then regularly for 5 years. A certain number of cardiac pathologies are known to cause P wave changes. The incidence of atrial fibrillation (AF) was much higher in VVI than in DDD patients. In the VVI group, the incidence was much greater in patients paced for sinus node disease than in patients paced for AVB. Analysis of sinus P wave characteristics in 320 patients with VVI pacemakers shows progressive abnormalities of atrial function with time. The expression of this atrial dysfunction is a statistically significant prolongation of the P wave in V1 and dII and of the terminal part of the P wave in V1. The factors responsible for this abnormality and which favours the occurrence of AF are quasi-permanent pacing, the presence of retrograde conduction and an abnormality of atrial activation at the time of implantation.

Abstract
Left ventricular filling may be studied non-invasively by Doppler echocardiographic recording of transmitral blood flow. This study reports the variations in this flow induced by changing cardiac preload by administering trinitrin or by vascular filling in 27 patients undergoing catheterisation. Left ventricular end diastolic pressure (LVEDP) was measured by the pig-tail catheter used for ventriculography. Transmitral flow was recorded by pulsed Doppler using the apical view. The parameters studied were those of the early diastolic E wave and the end diastolic A wave. The hemodynamic and echocardiographic measurements were performed under basal conditions, after trinitrin and after vascular filling. Trinitrin was given to 14 patients and led to a fall in LVEDP from 17.6 +/- 4.5 to 6.7 +/- 1.4 mmHg (p less than 0.001). The amplitude of the mitral E wave decreased and the E/A ratio fell from 0.93 +/- 0.37 to 0.71 +/- 0.32 (p less than 0.001). Thirteen patients underwent vascular filling which increased LVEDP from 10.9 +/- 5 to 27 +/- 4 mmHg (p less than 0.001). The mitral E wave increased and the E/A ratio rose from 0.96 +/- 0.32 to 1.27 +/- 0.23 (p less than 0.01). The patients received trinitrin and then underwent vascular filling. The LVEDP decreased from 16 +/- 3.9 to 8 +/- 2.9 mmHg (p less than 0.001) and then rose to 28.3 +/- 3.5 mmHg (p less than 0.001). The E/A ratio fell after trinitrin from 0.91 +/- 0.40 to 0.58 +/- 0.30 (p less than 0.01) and then rose to 1.42 +/- 0.60 (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Intravenous nicardipine, 5 mg, was administered in two comparable groups of eight patients with chronic coronary artery disease but no clinical signs of heart failure. One group had received no previous treatment and served as a control group, and the other had received long-term treatment with large oral doses of propranolol. Blood concentrations of nicardipine were higher, and the area under the plasma concentration curve was greater in the group previously treated by propranolol. The total clearance of nicardipine was decreased in patients taking propranolol, without a change in the half-life of the drug. Typical hemodynamic responses, namely, a decrease in aortic pressure and in arterial resistances, were greater and more lasting in patients previously treated orally by propranolol. Filling pressure remained stable in both groups. The nicardipine infusion did not induce signs of dromotropic or inotropic negative effects in either group. The greater and more lasting hemodynamic effects of nicardipine in the group previously treated orally by propranolol do not seem to be related to an overall hemodynamic action of propranolol, but are probably due to higher nicardipine plasma levels, and may be caused by a decrease in hepatic blood flow induced by propranolol, with a consequent decrease in nicardipine clearance and by a smaller nicardipine volume of distribution in the propranolol group.

Abstract
This study is an investigation of the long-term effects of VVI pacing on the atrium as derived from the evolution of P wave characteristics of 285 patients. The occurrence of left and right atrial disease is demonstrated as well as the evolution of left atrial hypertrophy in some cases. A comparison is made with DDD pacing and special attention is given to the progression to atrial fibrillation.

Abstract
Obstructive calcification of the thoracic aorta appears as acquired coarctation of the aorta. The case we present is of note because it presented as a dilated cardiomyopathy. The diagnosis, suspected on chest X-ray, was confirmed by catheterization, aortic angiography and thoracic computer tomography. The patient underwent aortic endarterectomy, but died in the post-operative period. Review of the literature shows that the pathogenesis of the condition remains unclear.

Abstract
We are reporting a case of malignant pheochromocytoma surgically treated initially for an isolated left pararenal localization, and which recurred several years later accompanied with numerous metastases. Despite of a treatment with Iodine 131 MIBG, the evolution was rapidly fatal with a picture of cardiac failure. This cardiac involvement would be linked to a myocarditis directly secondary to the catecholamines and causing a marked increase of the free fatty acids concentration in the heart tissue. In reference to this case, all the data which may tend to suspect the malignant nature of a pheochromocytoma, present in 10 p. cent of the cases, are successively reviewed. There is no clinical specificity. The presence of a mixed secretion with marked urinary dopamine secretion, would not present, for all authors, the same criteria of specificity. Thoraco-abdominal scan and scintigraphy with iodine 131 MIBG are the two tests permitting to demonstrate, with a great sensitivity and specificity, an extra-adrenal localization, which is the best argument in favor of a malignancy since 30 to 40 p. cent of extra-adrenal pheochromocytomas are malignant, more especially as the metastases are located in areas where there are no embryonic remnants of tissues containing chromaffin cells. This permits to appreciate the difference between a non-malignant multicentric pheochromocytoma and a malignant pheochromocytoma. The ideal treatment of a malignant pheochromocytoma rests on surgery under the condition that there are ony one or two metastases. This procedure is preceded by a sodium nitroprusside preparation and followed with an alpha-blockers treatment. In case of multiple metastases, the therapeutic use of iodine 131 MIBG seems to be a tempting alternative.

Abstract
A case of left intraventricular thrombus, developed from a myxoid mitral valve and revealed by embolic cerebral vascular accidents at the end of a pregnancy, is reported. The links between a mitral valve prolapse and cerebral vascular accidents of embolic origin are studied during pre- and post-partum periods, where coagulation alterations are reviewed. It appears that, in pregnant women with a mitral valve prolapse, there is a maximum risk of developing an intra-cardiac thrombus in the last four weeks of pregnancy or immediately after delivery; this justifies, during that time, a thorough sonocardiographic monitoring.

Abstract
After having reported the case of a pheochromocytoma associated to Recklinghausen's disease, the authors define the best criteria of detection and localization of the pheochromocytoma and study its association to phacomatoses. Headaches, bouts of tachycardia and excessive inappropriate diuresis are the most evocative clinical signs of a pheochromocytoma. The different hormones and their urinary metabolites must be titrated separately and repeatedly. Two other examinations, scanner and scintigraphy with MIBG, visualize quite reliably the tumor foci. Calcium inhibitors are quite effective in sudden blood pressure rises. The association described here, may be explained by the fact that the two pathologies belong to the group of neurocristopathies.

Abstract
The decision of whether or not to treat a ventricular extrasystole depends in the first instance on the benign or severe nature of the disorder, and on whether there is subjacent cardiopathy. The results of 24-hour Holter monitoring, exercise tolerance tests and clinical and echographic examinations will define the pathological character of a ventricular extrasystole and will indicate any subjacent cardiopathy. Electrophysiological exploration with programmed stimulation should be reserved for so-called lethal cases of arrhythmia, such as attacks of sustained ventricular tachycardia. Ischemic cardiopathy is by far the most frequent cause of ventricular extrasystoles. The two major risks of sudden death after myocardial infarction are due to left ventricular dysfunction and repetitive and/or complex ventricular extrasystoles, as well as to attacks of ventricular tachycardia. Heart patients presenting these disorders must receive urgent treatment with antiarrhythmics. Isolated, monomorphic ventricular extrasystoles are also treated in heart patients at risk if their frequency is greater than 10 per hour, measured by 24-hour Holter monitoring. In the absence of subjacent cardiopathies, the therapeutic indications are much less well defined. Approximately five per cent of subjects in a normal population present ventricular extrasystoles, the frequency of which, however, rarely exceeds 100 per 24 hours. Repetitive phenomena are only seen in 10 per cent of cases. Attacks of ventricular tachycardia are almost never seen. Ventricular extrasystoles that develop in apparently normal hearts, but which do not fulfill the above criteria, can be considered abnormal. Nevertheless, there is no categorical proof that these ventricular extrasystoles represent any risk, notably of sudden death.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The authors report the case of a serious cardiovascular complication due to naftidrofuryl overdosage following its intravenous administration. Other similar complications have already been reported in the literature and in experimental animal studies (particularly involving the conduction system of the heart). Since naftidrofuryl belongs to the class of local anesthetics and is pharmacologically related to procainamide, certain precautions must be closely followed if it is administered intravenously: avoidance of rapid injection directly into the vein, limiting the infusion to 200 to 400 mg given over a 3 hour period using preferably a constant infusion syringe pump or an infusion pump, and using caution when associated with other medications, particularly antiarrhythmic agents which could affect atrioventricular or intraventricular conduction.
