Embracing the polypill as a cardiovascular therapeutic: is this the best strategy?

The CNIC-polypill (acetylsalicylic acid, atorvastatin, and ramipril), an effective and cost-saving secondary prevention strategy compared with other therapeutic options in patients with ischaemic heart disease

Aims

The retrospective NEPTUNO study evaluated the effectiveness of the Centro Nacional de Investigaciones Cardiovasculares (CNIC)-polypill (including acetylsalicylic acid, ramipril, and atorvastatin) vs. other therapeutic approaches in secondary prevention for cardiovascular (CV) disease. In this substudy, the focus was on the subgroup of patients with ischaemic heart disease (IHD).

Methods and results

Patients on four strategies: CNIC-polypill, its monocomponents as loose medications, equipotent medications, and other therapies. The primary endpoint was the incidence of recurrent major adverse CV events (MACEs) after 2 years. After matching, 1080 patients were included in each cohort. The CNIC-polypill cohort had a significantly lower incidence of recurrent MACE compared with monocomponents, equipotent drugs, and other therapies cohorts (16.1 vs. 24, 24.4, and 24.3%, respectively; P < 0.001). The hazard ratios (HRs) for recurrent MACE were higher in monocomponents (HR = 1.12; P = 0.042), equipotent drugs (HR = 1.14; P = 0.031), and other therapies cohorts (HR = 1.17; P = 0.016) compared with the CNIC-polypill, with a number needed to treat of 12 patients to prevent a MACE. The CNIC-polypill demonstrated a greater reduction in LDL cholesterol (LDL-c; -56.1 vs. -43.6, -33.3, and -33.2% in the monocomponents, equipotent drugs, and other therapies, respectively; P < 0.001) and systolic blood pressure (-13.7 vs. -11.5, -10.6, and -9.1% in the CNIC-polypill, monocomponents, equipotent drugs, and other therapies, respectively; P < 0.001) compared with other cohorts. The CNIC-polypill intervention was less costly and more effective than any other therapeutic option, with €2317-€2407 cost savings per event prevented.

Conclusion

In IHD, the CNIC-polypill exemplifies a guideline-recommended secondary prevention treatment linked to better outcomes and cost saving compared with other therapeutic options.

Bempedoic acid in the management of lipid disorders and cardiovascular risk. 2023 position paper of the International Lipid Expert Panel (ILEP)

Cardiovascular disease (CVD) is a chronic non-communicable disease (NCD) and the predominant cause of morbidity and mortality worldwide. Substantial reductions in the CVD prevalence have been achieved in recent years by the attenuation of risk factors (particularly hypertension and dyslipidaemias) in primary and secondary prevention. Despite the remarkable success of lipid lowering treatments, and of statins in particular, in reducing the risk of CVD, there is still an unmet clinical need for the attainment of guideline lipid-targets in even 2/3 of patients. Bempedoic acid, the first in-class inhibitor of ATP-citrate lyase presents a new approach to lipid-lowering therapy. By reducing the endogenous production of cholesterol, upstream of the rate-limiting enzyme HMG-CoA-reductase, i.e., the target of statins, bempedoic acid reduces circulating plasma concentrations of low-density lipoprotein cholesterol (LDL-C), and major adverse CVD events (MACE). Bempedoic acid has the potential to contribute to the reduction of CVD risk not only as monotherapy, but even further as part of a lipid-lowering combination therapy with ezetimibe, reducing LDL-C cholesterol up to 40%. This position paper of the International Lipid Expert Panel (ILEP) summarises the recent evidence around the efficacy and safety of bempedoic acid and presents practical recommendations for its use, which complement the 'lower-is-better-for-longer' approach to lipid management, which is applied across international guidelines for the management of CVD risk. Practical evidence-based guidance is provided relating to the use of bempedoic acid in atherosclerotic CVD, familial hypercholesterolaemia, and statin intolerance. Although there are still no sufficient data avilable for the role of bempedoic acid in the primary prevention of CVD, its favourable effects on plasma glucose and inflammatory markers makes this drug a rational choice in the patient-centred care of specific groups of primary prevention.

Red yeast rice for dyslipidaemias and cardiovascular risk reduction: A position paper of the International Lipid Expert Panel

The risk of atherosclerotic cardiovascular disease (ASCVD) is strongly related to lifetime exposure to low-density lipoprotein (LDL)-cholesterol in longitudinal studies. Lipid-lowering therapy (using statins, ezetimibe and PCSK9 inhibitors) substantially ameliorates the risk and is associated with long-term reduction in cardiovascular (CV) events. The robust evidence supporting these therapies supports their continued (and expanding) role in risk reduction. In addition to these 'conventional' therapeutics, while waiting for other innovative therapies, growing evidence supports the use of a range of 'nutraceuticals' (constituents of food prepared as pharmaceutical formulations) including preparations of red yeast rice (RYR), the product of yeast (Monascus purpureus) grown on rice, which is a constituent of food and is used in traditional Chinese medicine. The major active ingredient, monacolin K, is chemically identical to lovastatin. RYR preparations have been demonstrated to be safe and effective in reducing LDL-C, and CV events. However, surprisingly, RYR has received relatively little attention in international guidelines - and conventional drugs with the strongest evidence for event reduction should always be preferred in clinical practice. Nevertheless, the absence of recommendations relating to RYR may preclude the use of a product which may have clinical utility in particular groups of patients (who may anyway self-prescribe this product), what in the consequence might help to reduce population CV risk. This Position Paper of the International Lipid Expert Panel (ILEP) will use the best available evidence to give advice on the use of red-yeast rice in clinical practice.

The Era of Polypills in the Management of Cardiovascular Diseases: Are We There Yet?

Cardiovascular Diseases (CVD) are the leading cause of mortality globally. Wald and Law proposed the idea of a 'polypill'; a fixed dose combination therapy (FDC) in the form of a single pill to curb the CVD epidemic. Such a drug would include the combination of a broad spectrum of drugs including cholesterol lowering drugs, antihypertensive drugs, anti-platelet drugs, anti-coagulation drugs, anti-arrhythmic drugs, which are frequently integrated to combat specific CVDs. This 'polypill' holds the potential to pose several advantages like increased compliance, improved quality of life, risk factor control, psychological relief, and cost effectiveness along with minimal side effects. Several trials (like TIPS, UMPIRE, PolyIran etc.) have tested different treatment strategies to test the hypothesis of Wald and Law. Unlike the past physicians are now highly aware of this new strategy.The future of polypill in the management of CVD lies in a strategy where polypills are treated supplementary to the already existing preventive care, which includes lifestyle modifications and efforts to reduce tobacco use.

Colchicine and Cardiovascular Outcomes: a Critical Appraisal of Recent Studies

Purpose of Review

Recent studies have demonstrated an important role for inflammation in the pathogenesis of atherosclerotic cardiovascular disease. Several studies have investigated the efficacy of colchicine (a widely used and safe anti-inflammatory drug) in patients with atherosclerosis. This review explains the rationale for the use of colchicine in this setting and critically appraises recent outcome trials.

Recent Findings

Two large randomised-controlled trials LoDoCo2 (included patients with chronic coronary syndromes) and COLCOT (acute coronary syndromes) have demonstrated reductions in atherosclerotic cardiovascular events, but not mortality. A smaller study (COPS) found no beneficial effect of colchicine but was probably underpowered.

Summary

Colchicine is effective at reducing cardiovascular events in chronic and acute coronary syndromes, although reductions in all-cause mortality have not been demonstrated during the period of follow-up in trials to date. Mild gastrointestinal symptoms are the most commonly reported adverse effects, although in well-designed randomised controlled trials these are relatively uncommon.

The value of the polypill in cardiovascular disease: an Italian multidisciplinary Delphi panel consensus

The purpose of this work was to reach the consensus of a multidisciplinary and multistakeholder Italian panel on the value of polypill in cardiovascular disease, with respect to the clinical, technological, economic and organizational dimension. A three-step modified Delphi method was used to establish consensus. Eleven experts in the area of cardiology, pharmaceutical technology, general practice, hospital pharmacy, pharmacology, and health economics participated in the expert panel. To identify existing evidence concerning the value of polypill in the prevention of patients with cardiovascular disease, a systematic literature review was carried out according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement guidelines. In the first round, 22 statements were distributed to the panel. Panel members were asked to mark 'agree' or 'disagree' for each statement and provide any comments. The same voting method was again used for the second round. In the first round nine statements met consensus. In the second round, 10 statements reached consensus. Overall, consensus was reached for 19 statements representing five value polypill domains: clinical, technological, economic and organizational. During a final web meeting with all panel members consensus document open points were discussed. Panel members agreed to recognize polypill as effective in reducing cardiovascular events, blood pressure and lipids, cardiovascular risk and the weight of therapy, in therapeutic adherence improvement, in the absence of differences in bioavailability between drugs administered in fixed or free combinations and the better cost-effectiveness profile compared with standard care. This document represents a knowledge framework to inform decision makers of the value of polypill in cardiovascular prevention.

Optimal use of lipid-lowering therapy after acute coronary syndromes: A Position Paper endorsed by the International Lipid Expert Panel (ILEP)

Atherosclerotic cardiovascular disease (ASCVD) and consequent acute coronary syndromes (ACS) are substantial contributors to morbidity and mortality across Europe. Much of these diseases burden is modifiable, in particular by lipid-lowering therapy (LLT). Current guidelines are based on the sound premise that with respect to low density lipoprotein cholesterol (LDL-C), "lower is better for longer", and the recent data have strongly emphasized the need of also "the earlier the better". In addition to statins, which have been available for several decades, the availability of ezetimibe and inhibitors of proprotein convertase subtilisin/kexin type 9 (PCSK9) are additional very effective approach to LLT, especially for those at very high and extremely high cardiovascular risk. LLT is initiated as a response to an individual's calculated risk of future ASCVD and is intensified over time in order to meet treatment goals. However, in real-life clinical practice goals are not met in a substantial proportion of patients. This Position Paper complements existing guidelines on the management of lipids in patients following ACS. Bearing in mind the very high risk of further events in ACS, we propose practical solutions focusing on immediate combination therapy in strict clinical scenarios, to improve access and adherence to LLT in these patients. We also define an 'Extremely High Risk' group of individuals following ACS, completing the attempt made in the recent European guidelines, and suggest mechanisms to urgently address lipid-medicated cardiovascular risk in these patients.

Natural compounds as anti-atherogenic agents: Clinical evidence for improved cardiovascular outcomes

Atherosclerosis, a chronic progressive inflammatory condition characterized by the formation of lipid-laden lesions in arterial walls, is associated with substantial morbidity (including ischaemic stroke and myocardial infarction) and mortality. Risk factors for atherosclerosis are well understood and can be ameliorated by evidence-based and guideline-directed pharmaceutical agents (e.g. the reduction of circulating concentrations of low-density lipoprotein cholesterol by statins). Additionally, many natural products (usually food derivatives) and 'nutraceuticals' (pharmaceutical formulations prepared from components of foods) have been shown to have favourable effects on risk factors for atherosclerotic cardiovascular disease. This literature review summarises the evidence for anti-atherogenic natural compounds. The article focuses on agents which are discussed in international guidelines and are supported by extensive high-quality randomized-controlled trial (RCT) data. We focus on micronutrients (compounds present in food in small quantities) and nutraceuticals, in particular, phytosterols, polyunsaturated ω-3 fatty acids and red-yeast rice. We conclude that the 'nutraceutical approach' (identify the active ingredients in natural products; produce high-quality products according to Good Manufacturing Practice guidelines; evaluate them in long-term outcomes trials) is the mechanism by which the domains of natural product research and evidence-based medicine can move closer together.

Current state and future perspective of cardiovascular medicines derived from natural products

The contribution of natural products (NPs) to cardiovascular medicine has been extensively documented, and many have been used for centuries. Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. Over the past 40 years, approximately 50% of newly developed cardiovascular drugs were based on NPs, suggesting that NPs provide essential skeletal structures for the discovery of novel medicines. After a period of lower productivity since the 1990s, NPs have recently regained scientific and commercial attention, leveraging the wealth of knowledge provided by multi-omics, combinatorial biosynthesis, synthetic biology, integrative pharmacology, analytical and computational technologies. In addition, as a crucial part of complementary and alternative medicine, Traditional Chinese Medicine has increasingly drawn attention as an important source of NPs for cardiovascular drug discovery. Given their structural diversity and biological activity NPs are one of the most valuable sources of drugs and drug leads. In this review, we briefly described the characteristics and classification of NPs in CVDs. Then, we provide an up to date summary on the therapeutic potential and the underlying mechanisms of action of NPs in CVDs, and the current view and future prospect of developing safer and more effective cardiovascular drugs based on NPs.

The Role of Nutraceuticals in the Optimization of Lipid-Lowering Therapy in High-Risk Patients with Dyslipidaemia

PURPOSE OF REVIEW

We aimed to summarize recent guidelines, position papers, and high-quality clinical research relating the use of nutraceuticals in the management of individuals at high risk of atherosclerotic cardiovascular disease.

RECENT FINDINGS

It is essential that individuals at high risk of cardiovascular disease receive guideline-directed evidence-based therapies to reduce their risk of morbidity and mortality from cardiovascular events. Compared with conventional therapeutics, nutraceuticals have undergone relatively little investigation in randomized controlled trials. Thus, recommendations for nutraceuticals in international guidelines are rare, and nutraceuticals should not be used preferentially in place of statins. Nevertheless, recent position papers from the International Lipid Expert Panel and clinical evidence from studies of triglyceride reduction by polyunsaturated fatty acid administration demonstrate that nutraceuticals do have an important role in optimizing therapy in individuals at high risk of cardiovascular disease. Roles for nutraceuticals include as follows: (1) managing residual risk associated with lipids other than low-density lipoprotein cholesterol (LDL-C); (2) managing non-lipid-mediated residual risk; (3) optimizing LDL-C treatment in statin intolerance; (4) optimizing LCL-C treatment when add-on therapies for statins are not available; (5) as adjuncts to lifestyle for individuals at high lifetime risk of atherosclerotic cardiovascular disease (ASCVD). The strength of evidence for each of these applications is variable. In addition to guideline-directed therapeutics, nutraceuticals may have roles in optimizing preventative therapy and targeting residual risk in individuals at high risk of ASCVD. Application of Good Manufacturing Practice and randomized controlled trials when producing and evaluating nutraceuticals will expand the armoury of evidence-based agents for the prevention of ASCVD.

Perioperative Precision Medicine: Where Are We in 2020?

PURPOSE OF REVIEW

The present review examines how targeted approaches to care, based on individual variability in patient characteristics, could be applied in the perioperative setting. Such an approach would enhance individualized risk assessment and allow for targeted preventive and therapeutic decision-making in patients at increased risk for adverse perioperative events.

RECENT FINDINGS

Prior and current studies highlight valuable lessons on how future investigations attempting to link specific patient-related characteristics or treatment modalities with outcomes and adverse drug responses might be designed in the perioperative setting.

SUMMARY

Our review highlights the past, present, and future directions of perioperative precision medicine. Current evidence provides important lessons on how a specific patient and disease tailored approach can help perioperative physicians in delivering the most appropriate and safest perioperative care.

State-of-the-Art review: Hypertension practice guidelines in the era of COVID-19

The global burden of hypertension (HTN) is immense and increasing. In fact, HTN is the leading risk factor for adverse cardiovascular disease outcomes. Due to the critical significance and increasing prevalence of the disease, several national and international societies have recently updated their guidelines for the diagnosis and treatment of HTN. In consideration of the COVID-19 pandemic, this report provides clinicians with the best strategies to prevent HTN, manage the acute and long-term cardiac complications of HTN, and provide the best evidence-based care to patients in an ever-changing healthcare environment. The overarching goal of the various HTN guidelines is to provide easily accessible information to healthcare providers and public health officials, which is key for optimal clinical practice. However, the COVID-19 pandemic has challenged the ability to provide safe care to the most vulnerable hypertensive populations throughout the world. Therefore, this review compares the most recent guidelines of the 2017 American College of Cardiology/American Heart Association and multiple U.S. societies, the 2018 European Society of Cardiology/European Society of Hypertension, the 2019 National Institute for Care and Health Excellence, and the 2020 International Society of Hypertension. While a partial emphasis is placed on the management of HTN in the midst of COVID-19, this review will summarize current concepts and emerging data from the listed HTN guidelines on the diagnosis, monitoring, management, and evidence-based treatments in adults.

Fixed dose drug combinations - are they pharmacoeconomically sound? Findings and implications especially for lower- and middle-income countries

Introduction: There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered: Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary: FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drug:drug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.

Is type 2 diabetes mellitus a coronary heart disease equivalent or not? Do not just enjoy the debate and forget the patient!

In the last several years there has been a large debate whether patients with type 2 diabetes (T2DM) should be treated as those with high or very high cardiovascular risk, and whether T2DM should be considered as equivalent to coronary heart disease (CHD). It all started in the 2001 in National Cholesterol Education Program - Adult Treatment Panel III recommendations, and the knowledge has changed on this issue at least several times. But the main problem is that due to these inconsistencies and different approaches to the cardiovascular risk of T2DM patients, we have more and more patients with T2DM not effectively treated, and diabetologists mostly focus on glucose (glucocentric approach), often forgetting about the overall cardiovascular risk of those patients. In this review we discuss the above-mentioned topic, try to give some practical suggestions, and raise the issue of whether we should start a discussion on treating all patients with T2DM as those at very high cardiovascular risk, or to at least to try to unify the definition and find such variables/risk factors which are easy to measure to help physicians to treat those patients optimally. We have obviously discussed these issues in the context of new European Society of Cardiology (ESC)/European Association for the Study of Diabetes (EASD) Guidelines 2019.
