Real-world efficacy of inclisiran: data from a tertiary lipid clinic

Matthew M A Waite, Rehan Aftab, Edmund H Wilkes, Pritpal Padam, Lucy Barton, Shahenaz Walji, Ferruccio de Lorenzo, Kausik Ray, Alessia David, Benjamin Jones, Jaimini Cegla

Abstract

Small-interfering RNA (siRNA)-based therapies, such as inclisiran, offer a novel approach to reducing low-density lipoprotein-cholesterol (LDL-C) and preventing cardiovascular disease (CVD). Inclisiran inhibits proprotein convertase subtilisin/kexin type 9 (PCSK9) synthesis, enhancing LDL-receptor recycling and LDL-particle clearance. Although clinical trials have established its efficacy with LDL-C reductions of 44–52%, real-world studies have reported variable reductions over shorter follow-up periods. This study aimed to assess the long-term efficacy and safety of inclisiran in a diverse real-world cohort.

A total of 238 patients initiating inclisiran between January 2022 and January 2024 at a tertiary lipid service were included. Data on lipid profiles, comorbidities, and medication history were collected from electronic healthcare records. LDL-C reductions were analysed at each dose using a Bayesian hierarchical model, and subgroup analyses explored the influence of familial hypercholesterolaemia (FH) and baseline lipid-lowering therapy.

Inclisiran therapy resulted in a mean LDL-C reduction of 48.4% following the first dose, sustained over 27 months. Patients receiving three or more lipid-lowering therapies at baseline achieved greater LDL-C reductions compared with others (67.4% after first dose vs. 47.6%). No discernible differences in efficacy were observed between patients with and without FH. Inclisiran was well tolerated, with only six patients discontinuing therapy due to adverse events or preference. Approximately 35% of patients met the European Society of Cardiology LDL-C target of <1.4 mmol/L after the first dose, declining to 28% after the fourth dose.

These real-world findings demonstrate that inclisiran is a well-tolerated and effective lipid-lowering therapy, achieving reductions comparable with clinical trial results. Greater reductions in patients on multiple baseline therapies suggest the importance of comprehensive lipid management. While achieving stringent LDL-C targets remains challenging, inclisiran’s practical benefits, including infrequent dosing and good tolerability, underscore its potential to improve CVD outcomes in diverse populations.

Improving medication adherence in cardiovascular disease

Hassan Al-Riyami, Sunil K Nadar

Abstract

The management and prevention of cardiovascular diseases (CVD) is based on adequate adherence to medications and lifestyle changes. The reported rates of adherence with cardiovascular medications range from 30% to 70%, with patients often not taking all or part of their prescribed medications. The rates of non-adherence are even higher for individual cardiovascular risk factors. Assessment of medication adherence is an important part of the management of CVD. Many interrelated socio-economic and healthcare-related factors play a role in an individual patient’s adherence to medications. Understanding how these different factors affect each individual patient can lead to strategies that improve levels of adherence. This would help improve our control of CVDs, both at an individual patient level, and also at the level of national and international health.

Epidermis to endocardium: mapping the association between atopic dermatitis and infective endocarditis

Oscar Lau, Michelle Thomson, Derek Connolly, Xenophon Kassianides

Abstract

Infective endocarditis (IE) is a rare, life-threatening infection of the cardiac endocardium caused by bacterial seeding. On the other hand, atopic dermatitis (AD) is a common inflammatory skin condition that disrupts the epidermal barrier, increasing susceptibility to Staphylococcus aureus colonisation and recurrent bacteraemia. This provides a biologically plausible bridge to IE, which we explore in this current literature review.

MEDLINE, Embase and CENTRAL were searched from inception to 7 April 2025. Sixteen studies were included – 15 case reports and one retrospective cohort study – which were grouped into three categories: well-controlled AD with no predisposing risk factors, AD with predisposing risk factors, and uncontrolled AD or alternative AD management.

This review is made up of 24 patients with IE secondary to AD. Of the 16 studies, nine originated from Japan. Mean age was 29.6 years (range 15–42 years), which is significantly younger than classic IE cohorts (mean 60.0 years). Staph. aureus accounted for 23/24 patients, and the mitral valve was affected in 18/24 cases. In terms of patient outcomes, all but one patient survived, but valve surgery was necessary in 20/24 patients.

In conclusion, AD-related IE shows a distinct pattern: younger patients, Staph. aureus dominance and mitral valve involvement requiring mitral valve surgery in the majority. This potential link appears to be under-recognised, hence, greater cross-speciality awareness and rigorous AD control for those at high risk is recommended. The heavy Japanese skew in the literature highlights the need for broader case documentation in other regions to confirm this link across different patient demographics.

A case of hypertrophic cardiomyopathy with untoward outcome

Debjit Chatterjee

Abstract

Risk stratification for sudden cardiac death (SCD) and the selection of patients for prophylactic implantable cardiac defibrillator (ICD) in hypertrophic cardiomyopathy (HCM) are still evolving and far from ideal. I present a historical case of HCM that did not have recognised SCD risk factors. This case highlights the deficiency of the present risk-stratification strategy for HCM and European Society of Cardiology (ESC) risk-scoring system.

Exercise and competitive sport in those with genetic heart disease: what we know and what we don’t know. Part 1

Liam Fitzpatrick, Valerie Hayes, Habitha Sulaiman, Deirdre Ward, David Mulcahy

Abstract

Historically, young people with genetic heart diseases were discouraged from active sport due to concerns about the increased risk of sudden cardiac death during competitive or intensive exercise. The shock resulting from the sudden death of a young athlete, an event often highly publicised, tends to generate concern in the general population, and fear of litigation in a low-evidence area: both influence decision-making by the medical profession when discussing ‘restrictions’, especially in patients with genetic heart diseases, who by definition, are at increased risk of sudden cardiac death. In recent years, however, we have moved to a point where many athletes with certain genetic heart diseases can, with optimal medical therapy, be considered for involvement in various sporting and athletic pursuits. We are cautiously moving away from the assumption that exercise is contraindicated; we are factoring in the wishes of the patient-athlete (shared decision-making), and we are encouraging optimal protection for these athletes during their sporting endeavours (easily available automated external defibrillators [AEDs], and club personnel trained in basic life support [BLS]), while ensuring regular medical assessment to identify alterations in risk status. With dedicated follow-up of all such patient-athletes, we can refine our understanding of how best to advise (and protect) them in terms of exercise for enhanced quality of life.

Mapping the patient pathway for ICI cardiac toxicities: a single-centre case series with clinical practice insights

Yu-Hsuen Yang,* Shayan Datta,* Oluwabukola Thomas-Orogan, Susan Ellery, Anna Olsson-Brown

Abstract

Immune checkpoint inhibitors (ICIs) have revolutionised cancer care, but can cause serious cardiac immune-related adverse events (irAEs), particularly myocarditis, which carries up to 50% mortality. This study explores patient pathways to improve early recognition and management of ICI myocarditis in acute settings.

This was a retrospective, single-centre case series from a UK tertiary hospital with a specialist cardio-oncology multi-disciplinary team (MDT). Ten patients referred to the cardio-oncology MDT between March and August 2024 were included if diagnosed with myocarditis, pericarditis, or arrhythmias linked to ICI treatment. Clinical pathways were described using structured vignettes.

Seven patients had myocarditis, two pericarditis, and one bradyarrhythmia. Fatigue (57%) was the most common presenting symptom in myocarditis. Echocardiography was unremarkable in 86% of cases, while cardiac magnetic resonance imaging (MRI) confirmed myocarditis in 57%. N-terminal pro-B-type natriuretic protein (NT-proBNP) rose 17-fold from baseline compared with a four-fold rise in troponin T. Early MDT referral facilitated prompt diagnosis and treatment, while delayed recognition was associated with worse outcomes.

This case series highlights the importance of early MDT involvement, and the utility of additional cardiac biomarkers, such as NT-proBNP. It provides practical guidance to improve the acute care pathway for patients developing ICI-associated cardiac toxicities.

Machine learning in cardiology education: preparing the next generation for the AI era

Ismail Sooltan, Aqib Khan, Rajib Haque, Sudantha Bulugahapitiya

Abstract

Cardiovascular medicine is undergoing transformation driven by machine learning (ML) technologies.1 Algorithms now assist in imaging interpretation, electrocardiogram (ECG) analysis, and outcome prediction, with increasing sophistication.1,2 The adoption of ML-powered diagnostic tools in cardiology is growing, yet training programmes remain largely unchanged, creating a disconnect between skills taught and those required in contemporary practice.1–4

Despite rigorous clinical preparation, many cardiology trainees complete their education with insufficient knowledge of the ML technologies increasingly present in clinical workflows.5,6 As these applications become more prevalent, training programmes must integrate relevant ML education to ensure cardiologists can effectively evaluate, implement, and collaborate with artificial intelligence (AI) systems, rather than merely function as passive end-users of increasingly sophisticated technology.

User experience of a combined 2-in-1 home ECG and blood pressure monitor: a qualitative study

Ven Gee Lim, Cleo White, Lucy Gilbert, Faizel Osman

Abstract

We evaluated the usability of a novel 2-in-1 blood pressure (BP) and electrocardiogram (ECG) monitor (developed to facilitate earlier detection of hypertension and atrial fibrillation). Arrhythmia clinic patients and public volunteers were recruited. Key themes were generated from semi-structured interviews.

Patients (n=12) found the experience of measuring ECG and BP equally positive. Public volunteers (n=11) found BP measurement a more positive experience compared with ECG recording. Several key themes were generated: patient empowerment, investment in health, technical know-how, user requirements and ergonomics.

In conclusion, the 2-in-1 BP and ECG monitor received overall positive reviews, showcasing the device’s potential to enhance patient care in the management of hypertension and atrial fibrillation.

Now is the time to take syncope seriously

Richard Sutton, Frederik de Lange

Abstract

Syncope, as a symptom, remains poorly understood and handled in the UK. Personal involvement stemmed from successful abolition of syncope by cardiac pacing, initially in atrioventricular block then other bradycardias; UK facilities were sparse in the late 1970s. The aim was to broaden distribution and encourage understanding. To achieve this required abandoning the typical cardiology mindset and re-engaging with internal medicine. Syncope is poorly taught in medical schools, which implies that few physicians understand it and, therefore, cannot practise it to benefit patients. Syncope patients presenting in emergency departments (>1% of all) are frequently admitted to hospital to undergo numerous non-diagnostic tests, then discharged without diagnosis. Syncope has life-threatening causes in >1% of patients; given its prevalence, this represents a large number. Treatment is now possible.

Syncope science has notably advanced, offering valuable diagnostic and therapeutic strategies. Ubiquitous delivery in the UK requires a new approach, which has been applied in the Netherlands. Now, more than ever, is the time to take syncope seriously, with action now to address this critical situation.
