RESUMO

Atherosclerotic cardiovascular disease (ASCVD) remains the major cause of premature death and disability; effective cardiovascular (CV) risk prevention is fundamental. The World Heart Federation (WHF) Cholesterol Roadmap provides a framework for national policy development and aims to achieve ASCVD prevention.At the invitation of the WHF, a group of experts from the Portuguese Society of Cardiology (SPC), addressed the cholesterol burden at the national level and discussed possible strategies to include in a Portuguese cholesterol roadmap. The literature review showed that the cholesterol burden in Portugal is high and especially uncontrolled in those with the highest CV risk. An infographic, scorecard, was built to include in the WHF collection, for a clear idea about CV risk and cholesterol burden in Portugal, which would also be useful for health policy advocacy.The expert discussion and preventive strategies proposal followed the five pillars of the WHF document: Awareness improvement; Population-based approaches for CV risk and cholesterol; Risk assessment /population screening; System-level approaches; Surveillance of cholesterol and ASCVD outcomes. These strategies were debated by all the expert participants, with the goal of creating a national cholesterol roadmap to be used for advocacy and as a guide for CV prevention.Several key recommendations were made: Include all stakeholders in a multidisciplinary national program; Create a structured activities plan to increase awareness in the population; Improve the quality of continuous CV health education; Increase the interaction between different health professionals and non-health professionals; Increment the referral of patients to cardiac rehabilitation; Screen cholesterol levels in the general population, especially high-risk groups; Promote patients' self-care, engaging with patients' associations; Use specific social networks to spread information widely; Create a national database of cholesterol levels with systematic registry of CV events; Redefine strategies based on the evaluation of results; Create and involve more patients' associations - invert the pyramid order. In conclusion: ASCVD and the cholesterol burden remain a strong global issue in Portugal, requiring the involvement of multiple stakeholders in prevention. The Portuguese cholesterol roadmap can provide some solutions to help mitigate the problem urgently. Population-based approaches to improve awareness and CV risk assessment and surveillance of cholesterol and ASCVD outcomes are key factors in this change. A call to action is clearly needed to fight hypercholesterolemia and ASCVD burden.

RESUMO

BACKGROUND: Elevated levels of lipoprotein(a) (Lp(a)) are independently associated with an increased risk of atherosclerotic cardiovascular disease events. However, the mechanisms driving this association are poorly understood. We aimed to evaluate the association between Lp(a) and coronary plaque characteristics in a contemporary US cohort without clinical atherosclerotic cardiovascular disease, undergoing coronary computed tomography angiography, the noninvasive gold standard for the assessment of coronary atherosclerosis. METHODS: We used baseline data from the Miami Heart Study-a community-based, prospective cohort study-which included asymptomatic adults aged 40 to 65 years evaluated using coronary computed tomography angiography. Those taking any lipid-lowering therapies were excluded. Elevated Lp(a) was defined as ≥125 nmol/L. Outcomes included any plaque, coronary artery calcium score >0, maximal stenosis ≥50%, presence of any high-risk plaque feature (positive remodeling, spotty calcification, low-attenuation plaque, napkin ring), and the presence of ≥2 high-risk plaque features. RESULTS: Among 1795 participants (median age, 52 years; 54.3% women; 49.6% Hispanic), 291 (16.2%) had Lp(a) ≥125 nmol/L. In unadjusted analyses, individuals with Lp(a) ≥125 nmol/L had a higher prevalence of all outcomes compared with Lp(a) <125 nmol/L, although differences were only statistically significant for the presence of any coronary plaque and ≥2 high-risk features. In multivariable models, elevated Lp(a) was independently associated with the presence of any coronary plaque (odds ratio, 1.40, [95% CI, 1.05-1.86]) and with ≥2 high-risk features (odds ratio, 3.94, [95% CI, 1.82-8.52]), although only 35 participants had this finding. Among participants with a coronary artery calcium score of 0 (n=1200), those with Lp(a) ≥125 nmol/L had a significantly higher percentage of any plaque compared with those with Lp(a) <125 nmol/L (24.2% versus 14.2%; P<0.001). CONCLUSIONS: In this contemporary analysis, elevated Lp(a) was independently associated with the presence of coronary plaque. Larger studies are needed to confirm the strong association observed with the presence of multiple high-risk coronary plaque features.

RESUMO

Minimal change disease (MCD), typically linked with pediatric nephrotic syndrome, presents challenges in early identification and diagnosis in adult populations. This case report emphasizes the importance of tailored diagnostic and treatment approaches for adults with MCD. Our patient presented with fatigue, shortness of breath, and confusion, along with other symptoms leading to a renal biopsy which confirmed MCD. This highlights the diagnostic significance of kidney biopsy in adults. While steroids remain the standard treatment, challenges such as resistance and side effects lead to the consideration of alternatives like tacrolimus. There are nuanced differences between adult and pediatric MCD presentations, for which our study calls for increased awareness among physicians. Steroids are considered a first-line treatment for MCD, but prolonged use of steroids has significantly increased risk and alternative therapies should be considered. This study presents an example of MCD in adult populations, urging ongoing research for enhanced understanding and tailored management strategies. It emphasizes the pivotal role of physician awareness, alternative treatments, and continued investigation to improve outcomes for adults with MCD.

RESUMO

BACKGROUND: The International Atherosclerosis Society (IAS) published an evidence-informed guidance for familial hypercholesterolemia (FH) that provides both clinical and implementation recommendations. We reference examples of strategies from the literature to explore how these implementation recommendations can be tailored into implementation strategies at the local-level for stakeholders guided by a framework proposed by Sarkies and Jones. METHODS: Four authors of the IAS guidance selected two published exemplar implementation recommendations for detection, management, and general implementation. Each recommendation was described as an implementation strategy using Proctor's guidance for specifying and reporting implementation strategies. It recommends reporting the actor (who), action (what), action-target (who is impacted), temporality (how often), and dose (how much) for each implementation strategy. RESULTS: Detection: A centralized cascade testing model, mobilized nurses (actor) to relative's homes, after the diagnosis of the proband (temporality), once (dose) to consent, obtain a blood sample and health information (action) on relatives (action-target). MANAGEMENT: A primary care initiative to improve FH management included an educational session (action) with clinicians (action-target), computer-based reminder message and message to patients to have their cholesterol screened once (dose) at a visit or outreach (temporality) by researchers (actor). General: A partnership between a statewide public pathology provider, local public hospital network, primary health network, government health ministry, and an academic university (actors) was established to implement a primary-tertiary shared care model (action) to improve the detection of FH (action-target). CONCLUSIONS: We demonstrate that implementation recommendations can be specified and reported for different local contexts with examples on monitoring, evaluation, and sustainability in practice.

RESUMO

The degradation of low-density lipoprotein receptor (LDLR) is induced by proprotein convertase subtilisin/kexin type 9 (PCSK9), resulting in elevated plasma concentrations of LDL cholesterol. Therefore, inhibiting the interactions between PCSK9 and LDLR is a desirable therapeutic goal for managing hypercholesterolemia. Aptamers, which are RNA or single-stranded DNA sequences, can recognize their targets based on their secondary structure. Aptamers exhibit high selectivity and affinity for binding to target molecules. The systematic evolution of ligands by exponential enrichment (SELEX), a combination of biological approaches, is used to screen most aptamers in vitro. Due to their unique advantages, aptamers have garnered significant interest since their discovery and have found extensive applications in various fields. Aptamers have been increasingly utilized in the development of biosensors for sensitive detection of pathogens, analytes, toxins, drug residues, and malignant cells. Furthermore, similar to monoclonal antibodies, aptamers can serve as therapeutic tools. Unlike certain protein therapeutics, aptamers do not elicit antibody responses, and their modified sugars at the 2'-positions generally prevent toll-like receptor-mediated innate immune responses. The focus of this review is on aptamer-based targeting of PCSK9 and the application of aptamers both as biosensors and therapeutic agents.

RESUMO

Atherosclerosis is an inflammatory disease. Coronary artery calcium (CAC) is a marker of atherosclerotic disease events and mortality risk. Increased GlycA, an emerging marker of inflammation, is associated with a higher risk for coronary artery disease (CAD). However, there is conflicting evidence on whether GlycA predicts subclinical CAD progression. We hypothesized that GlycA can predict subclinical CAC incidence/progression in healthy participants. We included 2,690 ELSA-Brasil cohort participants without cardiovascular/chronic inflammatory disease not receiving statin therapy who had GlycA levels measured and 2 interval CAC assessments between 2010 and 2018. Multivariable logistic and linear regression models were computed to evaluate GlycA as a predictor of CAC incidence and progression. CAC incidence required a baseline CAC of 0. CAC progression required a baseline CAC >0. The mean age of participants was 48.6 ± 7.7 years, 56.7% were women, and 54.6% and 16.1% (429 of 2,690) were White and Black, respectively. The mean CAC interscan period was 5.1 ± 0.9 years, the mean GlycA level was 414.7 ± 65 µmol/L, and the incidence of CAC was 13.1% (280 of 2,129). The GlycA level odds ratio for CAC incidence was 1.002 (95% confidence interval 1.0005 to 1.005, p = 0.016), adjusted for demographics, lifestyle, a family history of early CAD (≤60 years), lipids, and co-morbidities. The GlycA (≤p25 vs ≥p75) odds ratio for CAC progression (Berry definition) was 1.77 (95% confidence interval 1.07 to 2.96, p = 0.03) in a similar multivariable-adjusted model. Higher GlycA levels were associated with CAC incidence and progression in a healthy Brazilian cohort.

RESUMO

The present theoretical essay is based on six reports concerning same-sex couples and gay and lesbian people in order to interconnect homoparenting and the adoption of children with disabilities, through the lenses of human and social sciences in public health. The reports were interpreted in light of studies on same-sex adoption and the adoption of children with disabilities. Feminist approaches related to care and disability were also included in the interpretative perspective, operating as expressive webs of grammars of ableism. It was found that media approaches endorse the right to family formation and the adoption of children with disabilities by homoparental families, but with little critical depth on the category of disability and without highlighting support for the adoption of all adoptee profiles. Moreover, the intersections between homophobia and ableism increase discriminatory and oppressive logics, with the union of social groups considered to be "undesirable" representing a strategy of governmentality that reveals the complexity of grammars of ableism, applied to the sexual and reproductive rights of LGBTQIA+ adopters and to the fundamental rights of children and adolescents with disabilities who are available for adoption.


O ensaio teórico parte de seis reportagens sobre casais homoafetivos e pessoas gays e lésbicas para interseccionar homoparentalidade e adoção de crianças com deficiência, pelas lentes das ciências humanas e sociais em saúde coletiva. As reportagens foram interpretadas à luz dos estudos sobre adoção homoparental e adoção de crianças com deficiência. Abordagens feministas sobre cuidado e deficiência também compuseram o olhar interpretativo, operando como teias expressivas das gramáticas do capacitismo. Verificou-se que as abordagens midiáticas endossam o direito à constituição familiar e à adoção de crianças com deficiência por famílias homoparentais, sem aprofundar criticamente a categoria deficiência e sem destacar apoio à adoção de todos os perfis de adotandos. E que as intersecções entre homofobia e capacitismo incrementam lógicas discriminatórias e de opressão, sendo a união de grupos considerados "indesejáveis" uma estratégia de governamentalidade que revela a complexidade das gramáticas do capacitismo aplicadas aos direitos sexuais e reprodutivos de adotantes LGBTQIA+ e aos direitos fundamentais de crianças e adolescentes com deficiência disponíveis para adoção.

RESUMO

Stable angina, one manifestation of chronic coronary syndrome (CCS), is characterised by intermittent episodes of insufficient blood supply to the myocardium, provoking symptoms of myocardial ischaemia, particularly chest pain. These attacks usually occur during exercise or stress. Anti-ischaemic drugs are the mainstay of pharmacologic management of CCS with symptoms of angina. ß-blockers reduce heart rate and myocardial contractility, thus reducing myocardial oxygen consumption. These drugs have been shown to ameliorate the frequency of anginal attacks and to improve exercise capacity in these patients. Current management guidelines include ß-blockers as a first-line management option for most patients with CCS and symptoms of myocardial ischaemia, alongside dihydropyridine calcium channel blockers (CCB). The presence of comorbid angina and heart failure is a strong indication for starting with a ß-blocker. ß-blockers are also useful in the management of angina symptoms accompanied by a high heart rate, hypertension (with or without a renin-angiotensin-aldosterone-system [RAS] blocker or CCB), or microvascular angina (with a RAS blocker and a statin). A ß-blocker is not suitable for a patient with low heart rate (<50 bpm), although use of a ß-blocker may be supported by a pacemaker if the ß-blocker is strongly indicated) and should be used at a low dose only in patients with low blood pressure.

RESUMO

BACKGROUND: Identification of biomarkers to distinguish between stable and unstable plaque formation would be very useful to predict plaque vulnerability. METHODS: We downloaded microarray profiles of gene set enrichment (GSE) accession numbers including GSE71226 and GSE20680 (group A: containing healthy vs stable plaque samples) and GSE62646 and GSE34822 (group B: containing stable vs unstable plaque samples) from Gene expression omnibus (GEO) database. Differentially expressed genes were compared in both data sets of each group. RESULTS: Ten and 12 key genes were screened in groups A and B, respectively. Gene Ontology (GO) enrichment was applied by the plugin "BiNGO" (Biological networks gene ontology tool) of the Cytoscape. The key genes were mostly enriched in the biological process of positive regulation of the cellular process. The protein-protein interaction and co-expression network were analyzed by the STRING (search tool for the retrieval of interacting genes/proteins) and GeneMANIA (gene multiple association network integration algorithm) plugin of Cytoscape, respectively, which showed that Epidermal growth factor (EGF), Heparin-binding EGF like growth factor (HBEGF), and Matrix metalloproteinase 9 (MMP9) were at the core of the network. Further validation of key genes using two datasets showed that Phosphodiesterase 5A (PDE5A) and Protein S (PROS1) were decreased in unstable plaques, while Suppressor of cytokine signaling (SOCS3), HBEGF, and Leukocyte immunoglobulin-like receptor B4 (LILRB4) were increased. CONCLUSION: The present study used several datasets to identify key genes associated with stable and unstable atherosclerotic plaque.

RESUMO

BACKGROUND: Statins are the main strategy to reduce dyslipidemia-related cardiovascular risk. Nevertheless, there is scarce evidence on the real-world statins use in primary care settings in low-middle-income countries. OBJECTIVE: We conducted a cross-sectional retrospective study using anonymized data routinely collected by community health workers in Brazil aimed to evaluate statin use and associated factors in a primary prevention population with cardiovascular risk enhancers. METHODS: Study population consisted of adults with hypertension, diabetes, and/or dyslipidemia. The primary and secondary outcomes were the proportion of individuals self-reporting statins use on any dose and high-dose statins/high-intensity lipid-lowering therapy (LLT), respectively. RESULTS: Of the 2,133,900 adult individuals in the database, 415,766 (19.5%) were included in the study cohort. From this cohort, 89.1% had hypertension, 28.9% diabetes, and 5.5% dyslipidemia. The mean age was 61.5 (standard deviation 14.5) years, 63.4% were female, and 61.0% were of mixed-race. Only 2.6% and 0.1% of individuals self-reported the use of statins and high-dose statins/high-intensity LLT, respectively. Older age (odds ratio [OR] 1.96; 95% confidence interval [CI] 1.88, 2.05, p < 0.001), living in the South region of Brazil (OR 4.39; 95% CI 3.97, 4.85, p < 0.001), heart failure (OR 2.60; 95% CI 2.33, 2.89, p < 0.001), chronic kidney disease (OR 1.49; 95% CI 1.35, 1.64, p < 0.001), and anti-hypertensive medications use (OR 4.38; 95% CI 4.07, 4.71, p < 0.001) were independently associated with statin use. CONCLUSION: In a real-world evidence study analyzing data routinely collected in a digitized primary care setting, we observed a very low use of statins in a primary prevention population with cardiovascular risk enhancers in Brazil. Socio-demographic factors and co-morbidities were associated with higher statins use rates.

RESUMO

Guillain-Barré syndrome (GBS) in post-transplant patients is a rare clinical presentation. Although in the literature this neurological condition has been mainly associated with viral infections secondary to immunosuppression, GBS should not only be suspected in patients with an acute condition. It is essential to always rule out a viral or bacterial cause, looking for the most common sources, i.e., urinary, respiratory, and gastrointestinal. The diagnosis of GBS is clinically based, and its management is based on the use of intravenous immunoglobulin (IVIG) or plasma exchange. Its timely diagnosis allows treatment to be started early, thus improving the prognosis of these patients and reducing the time of hospitalization and complications associated with it. This report shows how an interdisciplinary approach is vital in such cases, as both the precipitant and the disease must be managed to decrease the morbidity and mortality associated with this condition. It is crucial to evaluate the benefits and risks of withdrawing immunosuppressive treatment in post-transplant patients, and being able to recognize when restarting them is indicated.

RESUMO

BACKGROUND: Pediatric patients with homozygous familial hypercholesterolemia (HoFH) have an increased risk of atherosclerotic cardiovascular disease and difficulty meeting low-density lipoprotein cholesterol (LDL-C) goals. In this post hoc analysis, we evaluated pooled safety and efficacy data from 3 studies in pediatric patients with HoFH treated with the PCSK9 (proprotein convertase subtilisin/kexin type 9) monoclonal antibody inhibitor evolocumab. METHODS: Patients with HoFH aged 10 to 17 years received treatment with open-label evolocumab 420 mg subcutaneously monthly or biweekly in the TAUSSIG, RAMAN, or HAUSER-OLE clinical studies. All patients received background statins with or without ezetimibe. Study duration ranged from 12 to 260 weeks. The primary end point was treatment-emergent adverse events per 100 patient-years. Efficacy end points were changes from baseline to week 12 in lipids and PCSK9. RESULTS: Of the 39 patients in the pooled analysis, 69.2% were males, median age was 13.0 years, and 79.5% (31/39) had genotyped HoFH with LDLR pathogenic variants. Overall, median exposure to evolocumab was 18.2 (Q1, Q3: 3.0, 18.5) months. Treatment-emergent adverse events with an exposure-adjusted patient incidence rate of ≥5% were upper respiratory tract infection (6.6%), influenza (5.2%), and acne (5.0%) per 100 patient-years. Exposure-adjusted patient incidence of serious treatment-emergent adverse events was 13.3% per 100 patient-years. Excluding 4 patients receiving lipoprotein apheresis, week 12 median percentage change from baseline in LDL-C was -2.9% (Q1, Q3: -21.7, 1.5); however, 42.9% (15/35) of patients achieved ≥15% reduction in LDL-C from baseline. Residual LDLR (LDL receptor) activity was not associated with a reduction in LDL-C. CONCLUSIONS: In this pooled data analysis from 3 studies in pediatric patients with HoFH, evolocumab was well tolerated, with no new safety signals reported. These safety findings are consistent with findings from previous studies of evolocumab. Patients showed marked variability in LDL-C reduction. Results from this pooled analysis support guidelines suggesting a trial of PCSK9 inhibitor therapy regardless of estimated residual LDLR function.

RESUMO

Importance: Many pediatric patients with heterozygous familial hypercholesterolemia (HeFH) cannot reach recommended low-density lipoprotein cholesterol (LDL-C) concentrations on statins alone and require adjunct lipid-lowering therapy (LLT); the use of alirocumab in pediatric patients requires evaluation. Objective: To assess the efficacy of alirocumab in pediatric patients with inadequately controlled HeFH. Design, Setting, and Participants: This was a phase 3, randomized clinical trial conducted between May 2018 and August 2022 at 43 centers in 24 countries. Pediatric patients aged 8 to 17 years with HeFH, LDL-C 130 mg/dL or greater, and receiving statins or other LLTs were included. Following consecutive enrollment into dosing cohorts, 25 of 99 patients screened for dosing every 2 weeks (Q2W) failed screening; 25 of 104 patients screened for dosing every 4 weeks (Q4W) failed screening. A total of 70 of 74 Q2W patients (95%) and 75 of 79 Q4W patients (95%) completed the double-blind period. Interventions: Patients were randomized 2:1 to subcutaneous alirocumab or placebo and Q2W or Q4W. Dosage was based on weight (40 mg for Q2W or 150 mg for Q4W if <50 kg; 75 mg for Q2W or 300 mg for Q4W if ≥50 kg) and adjusted at week 12 if LDL-C was 110 mg/dL or greater at week 8. After the 24-week double-blind period, patients could receive alirocumab in an 80-week open-label period. Main Outcomes and Measures: The primary end point was percent change in LDL-C from baseline to week 24 in each cohort. Results: Among 153 patients randomized to receive alirocumab or placebo (mean [range] age, 12.9 [8-17] years; 87 [56.9%] female), alirocumab showed statistically significant reductions in LDL-C vs placebo in both cohorts at week 24. Least squares mean difference in percentage change from baseline was -43.3% (97.5% CI, -56.0 to -30.7; P < .001) Q2W and -33.8% (97.5% CI, -46.4 to -21.2; P < .001) Q4W. Hierarchical analysis of secondary efficacy end points demonstrated significant improvements in other lipid parameters at weeks 12 and 24 with alirocumab. Two patients receiving alirocumab Q4W experienced adverse events leading to discontinuation. No significant difference in adverse event incidence was observed between treatment groups. Open-label period findings were consistent with the double-blind period. Conclusions and Relevance: The findings in this study indicate that alirocumab Q2W or Q4W significantly may be useful for reducing LDL-C and other lipid parameters and be well tolerated in pediatric patients with HeFH inadequately controlled with statins.

RESUMO

The diabetic milieu is associated with cascades of pathophysiological pathways that culminate in diabetic complications and tissue injuries. Autophagy is an essential process mandatory for cell survival and tissue homeostasis by degrading damaged organelles and removing injured cells. However, it may turn into a pathological process in an aberrant mode in the diabetic and/or malignant milieu. Moreover, autophagy could serve as a promising therapeutic target for many complications related to tissue injury. Glp-1 mimetics are a class of newer antidiabetic agents that reduce blood glucose through several pathways. However, some evidence suggests that they can provide extra glycemic benefits by modulating autophagy, although there is no complete understanding of this mechanism and its underlying molecular pathways. Hence, in the current review, we aimed to provide new insights on the possible impact of Glp-1 mimetics on autophagy and consequent benefits as well as mediating pathways.

RESUMO

OBJECTIVES: Previous studies have shown a relation between the consumption of different types of meats and chronic disorders. This study aims to investigate the association between red and processed meat intake with metabolic syndrome (MetS) and its components in healthy obese and overweight women. METHODS: This cross-sectional study was conducted on Iranian women. The dietary assessment and body composition were measured by a validated food frequency questionnaire (FFQ) and bioelectrical impedance analysis, respectively. Blood samples were collected by standard protocols. RESULTS: A total of 231 women (mean age 36.47 ± 8.44 years) were included in the current study. After controlling for potential confounders, there was a marginally significant associations between higher intake of processed meat with the MetS (OR:1.01, 95% CI: 0.94,2.94, P:0.06) and high serum triglycerides (TG) (OR:1.27, 95% CI: 0.94,2.98, P:0.07). There was a significant associations between high intake of red meats with lower odds of higher waist circumference (WC) (OR:0.31, 95% CI: 0.10,0.97, P:0.04). Also, there was a significant associations were found between high intake of processed meats with greater odds of having lower high-density lipoprotein cholesterol (HDL-c) (OR:0.64, 95% CI: 0.30,0.95, P:0.03). CONCLUSIONS: The current study suggests that higher intakes of processed meat may be associated with the MetS in Iranian women with excess body weight, while this was not the case for red meat. More studies however are necessary in different communities to draw definitive conclusions.

RESUMO

PURPOSE: Inclisiran is the first small interfering RNA-based treatment approved for reducing pro-atherogenic lipoproteins in patients with heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease, who require additional lowering of low-density lipoprotein cholesterol (LDL-C). We report the first evaluation of the effects of inclisiran in a Middle East population. METHODS: We conducted a retrospective review of patients initiating inclisiran treatment at an outpatient diabetology, endocrinology, and cardiology center between May 2021 and December 2022. All patients followed up for 90 days or more, or with at least 1 lipid determination post initiation were included. Participants were categorized into primary prevention (n = 57) and secondary prevention (n = 89) groups according to previous atherosclerotic cardiovascular disease. FINDINGS: Inclisiran was initiated in 146 patients; mean (SD) age was 54.8 (12.12) years, 82 patients (56.2%) were male, 28 patients (19.2%) had received a diagnosis of familial hypercholesterolemia, 89 patients (61%) had received a diagnosis of diabetes mellitus, and 35 patients (23.9%) had a statin intolerance. Median (interquartile range) follow-up was 137 (90 to 193) days. At 90 days, median (interquartile range) reductions in serum LDL-C and triglycerides were -37.9% (-9.5% to -51.2%) and -12.0% (-9.8% to -40.5%), respectively, in primary prevention and -54.1% (-17.1% to -71.4%) and -15.3% (-14% to -38.8%), respectively, in secondary prevention (all, P < 0.001). LDL-C goals were attained in 110 patients (75.3%). Nonattainment of LDL-C goal was attributed to system effect in 26 patients (72.2%), biological effect in 5 patients (13.9%), and discontinuation of treatment in 5 patients (13.9%). Therapy was well tolerated. IMPLICATIONS: This study is the first from the Middle East and North Africa region that reported the real-world efficacy and safety profile of inclisiran in a mixed-risk population of patients with heterozygous familial hypercholesterolemia and other non-familial hypercholesterolemia indications. Clinically meaningful and sustained reductions in pro-atherogenic lipids with good tolerability were observed after inclisiran initiation. Fewer AEs were reported in this predominantly Arabic population, consistent with previous safety reports for inclisiran. It is important to note that no patient stopped inclisiran treatment due to AEs. Strengths of our study included an optimal cohort, patient heterogeneity, and high retention. In addition, we were able to report mean robust effects of inclisiran and good medication tolerability, quite like randomized studies and open-label extension periods. Despite this, our study had some limitations, including selection bias due to the retrospective design and the absence of a comparative group.
