Zusammenfassung. Wir berichten über eine 72-jährige Patientin, die nach einer elektiven Koronarangiografie über plötzlich einsetzende stärkste Kopfschmerzen klagte. Klinisch bestand eine dysphasische Aphasie, die sich rasch progredient zu einer globalen Aphasie und einem deliranten Zustandsbild entwickelte. Nach dem Ausschluss alternativer Differenzialdiagnosen gingen wir von der seltenen Komplikation einer kontrastmittelinduzierten Enzephalopathie nach Koronarangiografie aus.
A novel ultrathin-strut biodegradable polymer sirolimus-eluting stent (BP-SES) (Orsiro; Biotronik, Bülach, Switzerland) was shown to be superior to a thin-strut durable polymer everolimus-eluting stent (DP-EES) (XIENCE Xpedition/Alpine; Abbott Vascular, Santa Clara, CA, USA) with respect to the primary endpoint of target lesion failure (TLF) at 12 months in the pre-specified subgroup of patients with ST-segment elevation myocardial infarction (STEMI) included in the BIOSCIENCE trial. We designed a large-scale, randomised, clinical trial to assess the clinical superiority of ultrathin-strut BP-SES over thin-strut DP-EES among patients with STEMI undergoing primary percutaneous coronary intervention (PPCI).BIOSTEMI (NCT02579031) is a prospective, multicentre, randomised, controlled, superiority trial that will randomly assign 1,250 patients with STEMI undergoing PPCI to treatment with BP-SES or DP-EES. The primary endpoint of TLF, a composite of cardiac death, target vessel reinfarction, and clinically indicated target lesion revascularisation within 12 months, will be analysed with Bayesian models applied to the BIOSTEMI data set (n=1,250) using robust historical priors to incorporate historical information from the BIOSCIENCE STEMI subgroup (n=407).The BIOSTEMI trial will determine whether ultrathin-strut BP-SES are superior to thin-strut DP-EES with respect to TLF in patients with STEMI undergoing PPCI.
The overwhelming majority of patients with stress cardiomyopathy (SC) are postmenopausal women, suggesting an important pathophysiologic role of the female sex hormones. Preliminary data suggest that myocardial stunning might be provoked by estrogen deficiency.We hypothesized that, compared with age- and gender-matched patients with myocardial infarction (MI) or patients with normal coronary arteries, patients with SC would exhibit altered levels of sex hormones. Furthermore, we aimed to describe the clinical course and the pattern of sex hormones of the SC patients during long-term follow-up.Blood samples obtained on hospital admission were analyzed for estradiol (E2), progesterone (P), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) in women with SC (n = 17), age-matched women with acute MI (n = 16), and women with normal coronary arteries (n = 15). Six years after the initial event, SC patients underwent a clinical and echocardiographic follow-up and reassessment of sex hormones.Estrogen concentrations at hospital admission were significantly higher in the SC group compared with the MI and the control groups, with no difference in P, FSH, and LH concentrations. Follow-up E2 after 6 years in SC patients was lower than during the acute SC episode. Follow-up P in these patients was lower than P in the MI and control groups during the acute event, with a similar trend for E2. After a median follow-up of 6.4 years, 1 sudden cardiac death occurred and 2 patients suffered from SC recurrence.During the acute event, E2 concentrations are elevated in postmenopausal SC patients compared with women with acute MI or with normal coronary arteries. The higher E2 concentrations might have exerted atheroprotective effects and thus diverted the stress response to SC rather than MI. Recurrence and/or sudden cardiac death remains a potential risk of SC.
The proposed 2020 Core Curriculum for Percutaneous Cardiovascular Interventions aims to provide an updated European consensus that defines the level of experience and knowledge in the field of percutaneous cardiovascular intervention (PCI). It promotes homogenous education and training programmes among countries, and is the cornerstone of the new EAPCI certification, designed to support the recognition of competencies at the European level and the free movement of certified specialists in the European Community. It is based on a thorough review of the ESC guidelines and of the EAPCI textbook on percutaneous interventional cardiovascular medicine. The structure of the current core curriculum evolved from previous EAPCI core curricula and from the "2013 core curriculum of the general cardiologist" to follow the current ESC recommendations for core curricula. In most subject areas, there was a wide - if not unanimous - consensus among the task force members on the training required for the interventional cardiologist of the future. The document recommends that acquisition of competence in interventional cardiology requires at least two years of postgraduate training, in addition to four years devoted to cardiology. The first part of the curriculum covers general aspects of training and is followed by a comprehensive description of the specific components in 54 chapters. Each of the chapters includes statements of the objectives, and is further subdivided into the required knowledge, skills, behaviours, and attitudes.
Angiotensin-converting enzyme (ACE) inhibitors are established as first-line therapy in chronic heart failure (CHF). However, little is known about the dosage-plasma-level relationship of ACE inhibitors in CHF and its relation to drug-induced adverse effects. We investigated 45 patients (age 55 +/- 10 years) with stable CHF who presented with a maintenance dosage of enalapril of either 5 mg b.i.d. (E10, n = 16), 10 mg b.i.d. (E20, n = 18), or 20 mg b.i.d. (E40, n = 11). This dosage was changed three times to treat all patients with lower, higher, and, finally, the initial dosage for 4 weeks each. Patients were examined clinically, by questionnaire, and by spiroergometry. In addition, neurohormones (atrial and brain natriuretic peptide and norepinephrine), enalaprilat trough levels, and serum potassium and creatinine were measured. Enalaprilat trough levels differed significantly between the three groups at study entry but also varied markedly within each group. In addition to the dose of enalapril, serum creatinine, severity of CHF, basal metabolic rate, and body weight significantly influenced enalaprilat trough levels (R2 =.84, p <.001). Within-patient comparisons revealed that serum creatinine (107 +/- 26 versus 102 +/- 20 micromol/liter) and potassium (3.8 +/- 0.4 versus 3.7 +/- 0. 3mmol/liter) were higher, cough was more common (scored on a scale of 0-8: 1.7 +/- 2.1 versus 1.4 +/- 1.8), and blood pressure was lower (systolic, 112 +/- 14 versus 117 +/- 13 mm Hg; diastolic, 66 +/- 9 versus 69 +/- 11 mm Hg) on the highest than on the lowest enalaprilat trough level (all p <.05). Highly variable enalaprilat trough levels and the fact that adverse effects were more common on high enalaprilat trough levels provide a rationale for individually adjusting ACE-inhibitor dose in case of adverse effects.
