Introduction
In both primary and secondary cardiovascular (CV) prevention, the effectiveness of the programs depends on the adherence of professionals to clinical guidelines, access to indicated drugs by patients and patient adherence to the guidelines prescribed in the medium and long term. Clinical practice shows that the indications are often not followed by an important part of the actors, decreasing the effectiveness of cardiovascular prevention programs. An initiative proposes using polypills to improve adherence among healthcare providers and patients to these programs.[1]
The three most prevalent chronic conditions – diabetes mellitus (DM), hypertension (HTN) and dyslipidemia (PLD) – stand out as the diseases or cardiovascular risk factors (CVR) with the highest avoidable costs, for which each additional dollar spent on medications for patients who do adhere can generate between 3 and 13 dollars of savings alone. in preventable emergencies, visits to health care providers and hospitalizations.[2]
In primary CV prevention there are data demonstrating the effectiveness of prevention programs even when applied to the general population or people with low CVR; however, therapeutic strategies aimed at simultaneously controlling several CVR factors in patients without declared cardiovascular disease (primary prevention) are expensive and difficult to implement.[3,4]
In secondary CV prevention , patients with various CVR factors or with a history of ischemic heart disease (IC) have an elevated risk of recurrence of new coronary events. Combined pharmacological therapy is a common practice in secondary cardiovascular prevention even in geriatric patients and its benefits in morbidity and mortality are widely documented; However, the complexity of the therapeutic regimen often means that professionals tend not to implement a complete preventive regimen with lack of adherence to clinical guidelines, do not question the patient about their adherence to treatment and, in turn, that [5,6,7]patients present a low adherence to the therapeutic regimen with multiple medications; in these cases adherence to the therapeutic regimen is usually low after 6 months [4]even after acute myocardial infarction (AMI), while the use of a polypill after this period reduces the rate of major cardiovascular events.[8,9,10]
The consequences of this lack of therapeutic adherence are: increase in the rate of major CV episodes (and,[3] consequently, morbidity and mortality in both primary and secondary prevention), non-adherence to treatments for other related diseases or their delayed diagnosis (such as DM) due to less medical consultation; All this leads to an increase in the care burden and an increase in healthcare costs. Therapeutic adherence is a key factor in ensuring the sustainability of the healthcare system, as non-adherence is linked to poorer health outcomes and higher costs for the system.[11,12,13]
The polymer containing in different doses Acetylsalicylic Acid (ASA) plus Ramipril and Atorvastatin has shown its clinical effectiveness and high tolerability. According to its technical sheet, the indication focuses on [14,15,16] the secondary prevention of cardiovascular accidents as substitution treatment in adult patients adequately controlled with the three substances taken at the same time at equivalent doses to reduce the risk of suffering a CV accident when the patient has already suffered a previous event, not including the primary prevention of accidents CV, despite the evidence in the sense of providing benefits.[12,17]
The strategies using polypills for secondary CV prevention have shown greater comfort for the patient and an increase in adherence to treatment up to 20%, improving not only the CVR factors [8,13,17,18,19,20] but also reducing CV events and the health expenditure derived from them, being considered a strategy of great cost-effectiveness. [20,21,22]
The change to a polypill with this composition has as advantages the increase in the use [13,18] of Antiplatelet Agents (AAP) and [11] more favorably modify the levels of total cholesterol, LDL-cabbage, HDL-cabbage and[23] blood pressure, [11] than in patients who follow treatment with [14]three separate drugs, especially in people with a history of non-adherence or who have some [24] Predictor of lack of pharmacological adherence, in patients who are not well controlled with equipotent doses and with adherence problems, in patients who are controlled with individual drugs, and in patients with comorbidities and polymedicated.
The benefits of the association of ASA + Ramipril + statins are essentially due[18] to the increase in therapeutic compliance (more accentuated in antihypertensive drugs and in ASA, above statins). [24] The simplification of the therapeutic regimen and the increase in adherence in the short, medium and long term[11] show that for every 10% increase in adherence, cardiovascular complications decrease by 6.7%; assuming that the polypill increases adherence by up to 20%, the reduction in complications could be around 12.6% (up to 11 fatal and 46 non-fatal episodes per 1 [24]. 000 patients treated), pointing out its enormous cost-effectiveness, especially in a [13,21,22]country like Spain where the polypill has a price identical to the sum of its components in a separate generic version; in polymedicated patients, the simplification of the therapeutic regimen also results in better compliance with treatment guidelines for other conditions and diseases by indirectly increasing adherence to treatment treatments the others because they have a simpler regimen of administration of all medications. The use of fixed combination treatments is associated with a greater than expected reduction in blood pressure and lipid levels, due to increased therapeutic adherence. In phase IV studies, the reduction in blood pressure and LDL-cabbage was kept after one year of treatment, reducing cardiovascular risk factors.[13,32,35]
The indications of a polypill may include patients with high or very high CVR ([1]subclinical CV disease) to control their risk factors and as organic protection, provided that they do not present a high risk of bleeding in three types of patients: hypertensive patients with high CVR, primary CV prevention in patients with all three CVR factors present and in secondary CV prevention in patients controlled with all three components. [13,15,18,25] First, hypertensive patients with high CVR, defined by one or more of the following criteria: age ≥70 years, risk ≥10% at 10 years in the SCORE2 table adapted to the risk of their European region, risk ≥5% at 10 years in the SCORE table calibrated for Spain, risk ≥10% for the REGICOR or Framingham tables, left ventricular hypertrophy, microalbuminuria[16,26,27,28,29,30] or proteinuria, renal failure, increased pulse wave velocity, increased carotid intimomedial thickness, presence of atheromatous plaques and pathological ankle-brachial index. [31] Secondly, as primary prevention of cardiovascular events in patients with indications for treatment with all three components, patients with subclinical CV disease (patients with elevated or very high CVR and low risk of bleeding),[31,32] diabetics over 50 years of age with at least one associated CVR factor or with chronic kidney disease and microalbuminuria or macroalbuminuria, hypertensive patients with high CVR , patients with high CVR with clinical or subclinical ventricular dysfunction. Thirdly, it could also be indicated as secondary prevention of cardiovascular events in adult patients adequately controlled with monocomponents administered concomitantly at equivalent therapeutic doses, coronary complications, ischemic cerebrovascular or symptomatic peripheral arterial disease and patients with coronary stent.[5,16,25,31,32,33,34]
The use of a polypill could increase the adherence of patients to medication by reducing their CVR in the medium and long term, resulting in greater effectiveness of cardiovascular prevention programs without increasing costs or pressure on the health system.
