»Imitation is the means, not the end, of art« - Peter Paul Rubens und Sir Joshua Reynolds über die Grammatik antiker Skulptur

In der vorliegenden Besprechung von Peter Paul Rubens’ Lehrschrift De imitatione statuarum (um 1610) und Sir Joshua Reynolds’ Discourse on Sculpture (1780) wird der Versuch unternommen, das Lehrgerüst der Grammatik als ein gemeinsames Referenzmodell herauszuarbeiten und die Position dieser beiden Malergrößen innerhalb der neuzeitlichen Kunsttheorie genauer zu verorten. Hierbei werden besonders die medienspezifischen Eigenschaften von Skulptur im Verhältnis zur Malerei diskutiert, die Maler bei der Nachahmung von antiker Skulptur zu beachten haben.

Impact of B-type natriuretic peptide on short-term clinical outcomes following transcatheter aortic valve implantation

Aims: We aimed to assess the impact of B-type natriuretic peptide (BNP) on short-term outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). Methods and results: Of 500 consecutive patients with severe aortic stenosis undergoing TAVI at our institution, we studied 340 patients who had a BNP assessment prior to TAVI. Patients were divided into tertiles - low: BNP ≤201 pg/mL (n=114), mid: BNP 202-595 pg/mL (n=113) and high: BNP ≥596 pg/mL (n=113). The primary endpoint was all-cause mortality, cardiac death and major adverse cardiac and cerebrovascular events (MACCE; death, major stroke and myocardial infarction) at 30 days. Compared with low tertile, high tertile patients were at higher baseline surgical risk (STS score 5.5±3.0 vs. 7.4±4.1, p=0.002). On echocardiography, high tertile patients had smaller valve areas (0.74±0.21 vs. 0.66±0.23 cm2, p=0.008), higher left ventricular (LV) mass indices (123.40±33.66 vs. 168.22±47.96 g/m2, p<0.001) and lower LV ejection fractions (61.59±7.18 vs. 42.65±15.41%, p<0.001) as compared with low tertile patients. At 30 days, a significantly higher incidence of death (hazard ratio [HR] 7.41, p=0.001) cardiac death (HR 5.82, p=0.006) and MACCE (HR 9.04, p<0.001) was observed among high as compared to low tertile patients. Conclusions: In TAVI patients, higher BNP values at baseline are associated with an increased risk for an adverse event periprocedurally and after 30 days, respectively.

Impact of stent overlap on long-term clinical outcomes in patients treated with newer-generation drug-eluting stents

Aims: Early-generation drug-eluting stent (DES) overlap (OL) is associated with impaired long-term clinical outcomes whereas the impact of OL with newer-generation DES is unknown. Our aim was to assess the impact of OL on long-term clinical outcomes among patients treated with newer-generation DES. Methods and results: We analysed the three-year clinical outcomes of 3,133 patients included in a prospective DES registry according to stent type (sirolimus-eluting stents [SES; N=1,532] versus everolimus-eluting stents [EES; N=1,601]), and the presence or absence of OL. The primary outcome was a composite of death, myocardial infarction (MI), and target vessel revascularisation (TVR). The primary endpoint was more common in patients with OL (25.1%) than in those with multiple DES without OL (20.8%, adj HR=1.46, 95% CI: 1.03-2.09) and patients with a single DES (18.8%, adj HR=1.74, 95% CI: 1.34-2.25, p<0.001) at three years. A stratified analysis by stent type showed a higher risk of the primary outcome in SES with OL (28.7%) compared to other SES groups (without OL: 22.6%, p=0.04; single DES: 17.6%, p<0.001), but not between EES with OL (22.3%) and other EES groups (without OL: 18.5%, p=0.30; single DES: 20.4%, p=0.20). Conclusions: DES overlap is associated with impaired clinical outcomes during long-term follow-up. Compared with SES, EES provide similar clinical outcomes irrespective of DES overlap status.
