The use of the CNIC-Polypill in real-life clinical practice: opportunities and challenges in patients at very high risk of atherosclerotic cardiovascular disease - expert panel meeting report.

Although the cardiovascular (CV) polypill concept is not new and several guidelines state that a CV polypill should be considered an integral part of a comprehensive CV disease (CVD) prevention strategy, there are still some barriers to its implementation in the real-world setting, mainly in secondary CV prevention. As the CNIC-polypill is the only one approved for secondary CV prevention in patients with atherosclerotic CVD in 27 countries worldwide, a panel of four discussants and 30 participants from 18 countries conveyed in a virtual meeting on April 21, 2022, to discuss key clinical questions regarding the practical use of the CNIC-Polypill and barriers to its implementation.Data presented showed that, although the use of the CV polypill is not explicitly mentioned in the current 2021 European Society of Cardiology guidelines on CVD prevention, it may be used in any patient for secondary CVD prevention tolerating all their components to improve outcomes through different aspects. The favourable results of the Secondary Prevention of Cardiovascular Disease in the Elderly (SECURE) trial now reinforce this recommendation. The panellists presented algorithms on how to switch from any baseline regimen when starting treatment with the CNIC-polypill in different situations, including patients with hypertension, dyslipidaemia, and a previous CV event; at discharge after a cardiovascular event; in chronic ischemic conditions; and in cases of polypharmacy. The panellists and expert discussants did agree that available studies conducted so far with the CNIC-polypill demonstrate that it is as efficacious as the monocomponents, equipotent drugs, or other therapies; reduces the risk of experiencing recurrent major CV events; improves medication adherence; reduces health care costs and resources compared to patients treated with loose drugs; and the patients prefer it over the multipill strategy.In conclusion, the data presented by the participants provided the evidence behind the use of the CNIC-polypill to help fulfil the goal of encouraging its adoption by physicians.

Practical Decision Algorithms for the Use of the Cardiovascular Polypill in Secondary Prevention in Europe.

The main objective of cardiovascular disease (CVD) prevention is to reduce morbidity and mortality. Despite recommendations on evidence-based pharmacological treatment and lifestyle changes, the control of CV risk factors such as hypertension or dyslipidaemia is not optimal. The use of a CV polypill, including guideline-recommended drugs, as a baseline therapy, may contribute to improving risk factors control either by improving the treatment adherence or by the synergistic effect of its components. The CNIC-Polypill is the first CV polypill approved in Europe as an effective strategy for secondary prevention, which contains acetylsalicylic acid, atorvastatin (in two optional doses), and ramipril (in three optional doses) in a single pill. The present practical clinical document aims to provide a guide for patient management after an acute coronary syndrome (ACS) or with chronic CVD (CCVD) with a strategy based on the CNIC-Polypill, also considering the need to add other therapies for a personalized treatment. The most suitable clinical scenarios for the CNIC-Polypill use are discussed: (a) in patients after an ACS at discharge, (b) in patients with CCVD (chronic coronary syndrome, stroke, or peripheral artery disease) with uncontrolled low-density lipoprotein cholesterol (LDL-c) and/or blood pressure levels and (c) in patients with CCVD with well-controlled risk factors to simplify treatment and reduce polypharmacy in the context of CCVD prevention.

Harnessing the heart's resistance to malignant tumors: cardiac-derived extracellular vesicles decrease fibrosarcoma growth and leukemia-related mortality in rodents.

The heart is known for its resistance to cancer. Although different conjectures have been proposed to explain this phenomenon, none has been tested. We propose that the heart microenvironment may exert anti-cancer properties. So, our objective was to test the anti-oncogenic potential of cardiac-derived extracellular vesicles (EVs). For that EVs secreted by cardiosphere-derived cells (CDCs, heart progenitor cells) were tested in vitro on fibrosarcoma HT1080. In vivo models comprised the xenograft HT1080 fibrosarcoma in athymic mice (n=35), and spontaneous acute lymphocyte leukemia in old rats (n=44). CDC-EVs were compared with two control groups: EVs secreted by bone-marrow derived mesenchymal stem cells (MSC-EVs) and phosphate-buffered saline (PBS). Injection of CDC-EVs led to a 2.5-fold decrease of fibrosarcoma growth in mice (p<0.01 and p<0.05 for human and rat EVs, respectively) vs PBS group. The effect was associated with 2-fold decrease of tumor cells proliferation (p<0.001) and 1.5-fold increase of apoptosis (p<0.05) in CDC-EV vs PBS mice. Salutary changes in tumor gene and protein expression were observed in CDC-EV animals. CDC-EVs reduced tumor vascularization compared with PBS (p<0.05) and MSC-EVs (p<0.01). Moreover, CDC-EVs increased leukemia-free survival (p<0.05) in old rats vs PBS. MiR-146, highly enriched in CDC-EVs, may be implicated in part of the observed effects. In conclusion, this study presents the first evidence that ties together the long-recognized enigma of the "heart immunity to cancer" with an antioncogenic effect of heart-derived EVs. These findings open up cancer as a new therapeutic target for CDC-EVs.

Cardiac and systemic rejuvenation after cardiosphere-derived cell therapy in senescent rats.

AIM: The aim is to assess the effects of CDCs on heart structure, function, gene expression, and systemic parameters in aged rats. Diastolic dysfunction is characteristic of aged hearts. Cardiosphere-derived cell (CDC) therapy has exhibited several favourable effects on heart structure and function in humans and in preclinical models; however, the effects of CDCs on aging have not been evaluated. METHODS AND RESULTS: We compared intra-cardiac injections of neonatal rat CDCs to vehicle (phosphate-buffered saline, PBS) in 21.8 ± 1.6 month-old rats (mean ± standard deviation; n = 23 total). Ten rats 4.1 ± 1.5 months of age comprised a young reference group. Blood, echocardiographic, haemodynamic and treadmill stress tests were performed at baseline in all animals, and 1 month after treatment in old animals. Histology and the transcriptome were assessed after terminal phenotyping. For in vitro studies, human heart progenitors from older donors, or cardiomyocytes from aged rats were exposed to human CDCs or exosomes secreted by CDCs (CDC-XO) from paediatric donors. Transcriptomic analysis revealed that CDCs, but not PBS, recapitulated a youthful pattern of gene expression in the hearts of old animals (85.5% of genes differentially expressed, P < 0.05). Telomeres in heart cells were longer in CDC-transplanted animals (P < 0.0001 vs. PBS). Cardiosphere-derived cells attenuated hypertrophy by echo (P < 0.01); histology confirmed decreases in cardiomyocyte area (P < 0.0001) and myocardial fibrosis (P < 0.05) vs. PBS. Cardiosphere-derived cell injection improved diastolic dysfunction [lower E/A (P < 0.01), E/E' (P = 0.05), end-diastolic pressure-volume relationship (P < 0.05) compared with baseline), and lowered serum brain natriuretic peptide (both P < 0.05 vs. PBS). In CDC-transplanted old rats, exercise capacity increased ∼20% (P < 0.05 vs. baseline), body weight decreased ∼30% less (P = 0.05 vs. PBS) and hair regrowth after shaving was more robust (P < 0.05 vs. PBS). Serum biomarkers of inflammation (IL-10, IL-1b, and IL-6) improved in the CDC group (P < 0.05 for each, all vs. PBS). Young CDCs secrete exosomes which increase telomerase activity, elongate telomere length, and reduce the number of senescent human heart cells in culture. CONCLUSION: Young CDCs rejuvenate old animals as gauged by cardiac gene expression, heart function, exercise capacity, and systemic biomarkers.

[Advanced glycation end-products: new markers of renal dysfunction in patients with chronic heart failure]. / Productos de glicación avanzada: nuevo marcador de disfunción renal en pacientes con insuficiencia cardíaca crónica.

BACKGROUND AND OBJECTIVES: Advanced glycation end-products (AGE) are implicated in the physiopathology and prognosis of heart failure (HF) and they accumulate in situations such as kidney failure (KF). Our objective was to analyze the relation between AGE and KF in patients with chronic HF. MATERIALS AND METHODS: 102 consecutive patients of our medical center were included. Clinical and analytical data were obtained, with measurement of glycated haemoglobin, brain natriuretic peptide, cystatin C and fluorescent AGE. Glomerular filtration rate (GFR) was estimated for each patient. RESULTS: 40.2% of patients presented GFR < 60 mL/min/1.73 m(2) and 11.7% had hidden kidney disease (HKD). AGE correlated positively with creatinine (r=0.685, p<0.001) and cystatin C (r=0.682, p<0.001) and negatively with GFR (r=-0.720, p<0.001). Medium value of fluorescent AGE in patients with KF was higher than those without KF (83.4 [3.3] URF vs 56.8 [2.1] URF, p<0.001). With regard to the diagnostic value for HKD, fluorescent AGE presented an area under the ROC curve higher than other parameters for KD such as cystatin C. In the multivariate analysis, fluorescent AGE were an independent biomarker of KD (OR 1.060; 95% CI 1.024-1.097; p=0.001). CONCLUSIONS: AGE act as a biomarker of KD in patients with chronic HF, both diabetics and non diabetics, being better than cystatin C in the detection of HKD.

Cystatin C provides more information than other renal function parameters for stratifying risk in patients with acute coronary syndrome.

INTRODUCTION AND OBJECTIVES: The protein cystatin C has a stable plasma concentration and is eliminated exclusively by the kidneys. The aim of this study was to determine the prognostic value of cystatin C in patients with acute coronary syndrome (ACS). METHODS: The prospective study included 203 hospitalized ACS patients. Clinical evaluation during the first 24 hours of hospitalization included a hemogram and measurement of creatinine, cystatin C, total and fractionated cholesterol and markers of myocardial necrosis. The glomerular filtration rate (GFR) was estimated using the MDRD (Modification of Diet in Renal Disease) equation. A comparison was made between two groups of patients divided according to a serum cystatin-C level above or below 0.95 mg/L. The mean follow-up period was 151 days. RESULTS: In total, 90 patients (44.3%) had a cystatin-C level < or =0.95 mg/L and 113 (55.7%) had a level >0.95 mg/L. Those with a cystatin-C level >0.95 mg/L had poorer in-hospital outcomes, including more frequent heart failure (51.3% vs. 13.3%; P=.001) and higher in-hospital mortality (17.6% vs. 3.3%; P=.001), as well as higher mortality throughout follow-up (22.0% vs. 5.6%; P=.001). Multivariate analysis adjusted for age, ejection fraction and troponin-I and high-sensitivity C-reactive protein concentrations showed that cystatin C was the most powerful independent predictor of a cardiovascular event (relative risk=1.91; 95% confidence interval, 1.03-3.53). Patients with a GFR >60 mL/1.73 m(2) and a cystatin-C level >0.95 mg/L had higher in-hospital mortality (10.2% vs. 3.9%; P=.001). CONCLUSIONS: Measurement of cystatin C in high-risk ACS patients may be clinically useful for risk stratification during hospitalization, particularly in those with a normal GFR.
