Background: Meticulous implantation strategies (i.e. lesion predilatation, stent sizing and postdilatation) are known to decrease lesion-oriented adverse events (LOCE) following percutaneous coronary intervention (PCI) with bioresorbable scaffolds. Their impact on PCI with drug-eluting stents remains unclear.

Objective: To assess the impact of meticulous implantation strategies on long-term LOCE in PCI with everolimus-eluting stents (EES).

Methods: This substudy of the AIDA trial (NCT01858077) focused on the evaluation of predilatation, stent sizing and postdilatation through analyses of vessel and device diameters at various locations around the lesion. Their interrelations were assessed using quantitative coronary angiography across various lesion locations. Logistic regression was used to evaluate how predictors influenced the primary outcome LOCE, which includes target lesion revascularisation (TLR), target-vessel myocardial infarction (TV-MI) and definite stent thrombosis (ST).

Results: LOCE occurred in 84 (7.7%) of 1098 lesions, mainly driven by TLR (63, 5.7%) and TV-MI (46, 4.2%), with ST occurring in 9 (0.8%) lesions. Predilatation and postdilatation were performed in 92 and 49% of lesions, respectively. The difference between the diameter of the predilatation balloon and the reference vessel diameter was significantly associated with an increased risk for LOCE (odds ratio 4.84, 95% confidence interval: 1.91-12.7) with significant interaction with diabetes (p for interaction = 0.04), thus disfavouring predilatation with oversized balloons.

Conclusion: The low LOCE rate (7.7%) over 5 years underscores the efficacy of PCI with EES. The use of 'oversized' balloons for predilatation was associated with an increased risk of LOCE by up to fivefold, a risk that was interestingly reduced in patients with diabetes mellitus.

Background: Phospholamban (PLN) p.Arg14del (R14del, R14^∆/+) is the most commonly identified pathogenic variant that causes cardiomyopathy in the Netherlands. Many disease characteristics are still unclear, including the phenotypic triggers, disease progression and disease-specific biomarkers. We aim to gain a better understanding of the R14^∆/+ pathophysiology by establishing a cohort across the R14^∆/+ disease spectrum.

Methods: The Disease spECifIc PatHways and modifiERs in PhosphoLambaN r14del cardiomyopathy (DECIPHER-PLN) cohort includes 101 participants, categorised as unaffected R14^∆/+ (n = 21), early affected R14^∆/+ (n = 42), end-stage R14^∆/+ (n = 28) and heart failure (HF) of another aetiology (n = 10). R14^∆/+ category was based on left ventricular ejection fraction, HF symptoms, electrocardiogram (ECG) and N‑terminal pro-brain natriuretic peptide concentrations. Of the 91 included R14^∆/+ carriers, 46 (51%) were female, with a mean age of 55 years (standard deviation: 14). Low-voltage ECG older age, arrhythmias, and conduction and repolarisation abnormalities were common in (early) affected R14^∆/+ carriers. Serum and plasma were collected from all participants. Induced pluripotent stem cells were generated from fibroblasts of end-stage R14^∆/+ patients and unaffected R14^∆/+ family members (n = 4) and differentiated into cardiomyocytes. Explanted heart tissue was obtained from R14^∆/+ patients undergoing cardiac surgery and patients with other HF aetiologies as control. Abnormal PLN protein localisation was confirmed in R14^∆/+ carriers.

Conclusion: DECIPHER-PLN comprises R14^∆/+ carriers across the disease and non-disease spectrum and can be used to identify disease-specific biological pathways and modifiers that play a role in R14^∆/+ cardiomyopathy. Using a multi-omics approach and in vitro disease modelling, we aim to identify novel biomarkers and improve our understanding of R14^∆/+ pathophysiology. Material is available upon request.

Objective: Lowering low-density lipoprotein cholesterol (LDL-C) reduces the risk of developing atherosclerotic cardiovascular disease (ASCVD). In the PENELOPE study, a guideline-based, protocol-led LDL-C-lowering strategy was applied in patients after myocardial infarction and resulted in 87% reaching target LDL‑C levels of ≤ 1.8 mmol/l within a median of 45 days. This study evaluated PENELOPE's legacy effect on LDL‑C levels after 1 year.

Methods: In the PENELOPE study, 999 patients with a myocardial infarction and a history of ASCVD and/or diabetes mellitus were included. If LDL-C > 1.8 mmol/l, lipid-lowering therapy was intensified in three consecutive steps: (1) high-intensity statin (HIST) monotherapy, (2) HIST + ezetimibe, and (3) HIST + ezetimibe + proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i). LDL‑C levels were monitored 4-6 weeks after each step. The primary objective of this study was to assess the prevalence of the LDL‑C target level of ≤ 1.8 mmol/l being maintained after 1 year.

Results: Data of 738 patients (74%) were available for 1‑year follow-up. The target LDL‑C level was met in 471 patients (64%). Median LDL‑C levels changed from 1.5 (1.2-1.7) mmol/l immediately after implementation of the protocol-led strategy to 1.6 (1.3-2.0) mmol/l after 1 year. Major treatment regimens were statin (58%), statin + ezetimibe (30%) and PCSK9i + ezetimibe (+ statin) (7%).

Conclusion: After a myocardial infarction, implementation of a protocol-led LDL-C-lowering strategy resulted in 87% of patients attaining the LDL‑C target level of ≤ 1.8 mmol/l within a median of 45 (32-77) days. At 1‑year follow-up, 64% maintained this target level and the median LDL‑C increased by 0.1 mmol/l.
