Lipid-lowering prescription patterns after a non-fatal acute coronary syndrome

Abstract Introduction After an acute atherosclerotic cardiovascular event, high-intensity lipid-lowering therapy (LLT) is needed to reduce the risk of recurrence. Moreover, despite 2016/2019 ESC/EAS guidance on lipid management according to risk, several studies indicate that most patients do not attain low-density lipoprotein-cholesterol (LDL-C) goals. The present study aims to describe LLT prescription patterns after a non-fatal acute coronary syndrome (ACS) and identify opportunities for improvement in secondary preventive measures, namely LDL-C control. Methods Retrospective cohort study featuring adults aged 40-80 residing in a Portuguese municipality Portugal, using Electronic Health Records between 2016 and 2022. Selected patients had ≥1 general practice appointment three years before the occurrence of an ACS, which was considered an index date. Sub-analysis was made based on patients’ age (under and high or equal to 65 years), gender, and whether their LDL-C levels were controlled according to gradual upper thresholds of 100 mg/dL in the period before the ACS event and 55 mg/dL at one-year post-ACS. Results Among the 544 selected patients, 270 were younger than 65 years. Females comprised 30% (164 patients) of the total cohort, 27% of the under-65 group, and nearly 38% of the 65 and older group. In younger patients, LDL-C levels were higher at presentation (132 mg/dL) and had a significantly greater decrease during the follow-up period compared to the older group. In the period before the ACS, 71.1% of men and 56.7% of women had no previous prescription of LLT, and younger patients had worse levels of LDL-C control (24.1%) compared to older patients (46.0%). One year post-ACS, the pattern of LLT revealed a substantial drop in patients without any LLT prescription from 66.7% to 13.6% and an increase in high-intensity LLT from 2.4% to 16.5%. Still, moderate-intensity LLT (66%) remained the most frequently used LLT. An increase in LLT potency was observed in the follow-up, although there was a decrease in patients achieving LDL-C control. Previous to the ACS event, 35.3% of men and 34.8% of women had initially controlled LDL-C levels according to defined thresholds, which significantly reduced to 11.3% and 8.5%, respectively, at one-year post-ACS. Conclusion Despite initiating or intensifying LLT after ACS, LDL-C goals were not achieved in approximately 9 out of 10 patients at 1-year follow-up, highlighting that the LLT adjustment was insufficient. Therefore, there is a need for better optimisation of LLT after ACS, unveiling an alarming gap in guideline implementation in clinical practice.

Factors influencing low-density-lipoprotein cholesterol after acute coronary syndrome and effectiveness of intensive teleconsultation monitoring, the teleobjectif cohort study

Abstract Context: Low-density lipoprotein cholesterol (LDL-c) plays a key role in the development and progression of atherosclerotic cardiovascular disease (ASCVD). Despite the availability of effective lipid-lowering treatments, patients who have experienced an acute coronary syndrome (ACS) continue to face a high risk of recurrent cardiovascular events and mortality. Achieving the recommended LDL-c target of <0.55 g/L in secondary cardiovascular prevention remains a significant challenge, with fewer than 30% of patients reaching this goal. Aim To investigate the factors influencing LDL-c control after ACS and the effectiveness of intensive teleconsultation monitoring to control LDL-c, even in sub-groups where control is poorest. Methods This bi-centric prospective cohort study conducted between december 2019 and december 2021 compared a group that received standard follow-up after an ACS with an interventional group that received regular follow-up by teleconsultation in addition of usual care to optimize lipid-lowering treatment. A subgroup analysis was carried out to examine the effect of teleconsultation in subpopulations known to be significantly associated with better or worse LDL-c control in the usual care group or described in the literature. Results 1602 patients met the inclusion criteria for our study (814 in the usual care group and 788 in the teleconsultation group). Baseline characteristics were similar between groups. In the usual care group, factors influencing lipid control included gender, diabetes, cardiology consultation, distance to the nearest cardiologist, social deprivation and initial LDL-C levels. Teleconsultation significantly improved LDL-C target attainment compared to usual care (74.7% vs. 26.6%, p<0.001 with multivariate analysis OR 5.06 [4.21 ; 6.07]), particularly benefiting geographically and socially disadvantaged patients. Conclusion Teleconsultation significantly improves lipid control in acute coronary syndrome patients compared to usual care. This universal intervention, particularly beneficial for geographically and socially disadvantaged patients, highlights the potential of telemedicine in enhancing cardiovascular management.analysis in usual care groupTeleconsultation effect in sub-groups

Sex-specific guideline target value attainment and prognostic value of low-density lipoprotein cholesterol in tertiary care

Abstract Background Factors contributing to guideline-target-level-attainment of low-density lipoprotein cholesterol (LDL-C) in countries with high healthcare expenditure are incompletely understood. Purpose the primary aim of this study was to test two hypotheses: 1) LDL-C control may be inferior in women versus men; 2) within the secondary prevention group, presence of a previous acute atherothrombotic event (acute myocardial infarction and stroke) may result in superior LDL-C control. Methods LDL-C levels and guideline target level attainment were determined in 4090 consecutive patients referred for myocardial perfusion single photon emission tomography (MPI-SPECT) between 2010 and 2016. Findings were validated in an independent cohort (n=1228) of consecutively enrolled patients in an outpatient cardiac rehabilitation program, between 2016 and 2023. Results About one third of patients (33%) were women, median age was 68 years, 1439 patients had a history of atherothrombosis, 759 patients a history of atherosclerosis without atherothrombosis, and 1892 were in primary prevention. LDL-C levels were higher and guideline target level attainment worse in women than in men in all three strata: age-adjusted difference in atherothrombosis 0.19 mmol/L (95%CI 0.03,0.35 mmol), guideline-target-value-attainment 39.5 % versus 49.4%, p<0.01; in atherosclerosis 0.33 mmol/L (95%CI 0.10-0.57), guideline-target-value-attainment 27.3 % versus 42.2 %, p<0.01; and in primary prevention 0.24 mmol/L (95% CI 0.13-0.38). This was confirmed in the validation cohort. LDL-C levels were higher and guideline-target-value-attainment worse in women versus men: age-adjusted difference age-adjusted difference 0.17 mmol/L (95%CI 0.02-0.33) guideline-target-value-attainment 43.8% versus 49.5%, After multivariate adjustment, female sex remained an independent predictor for higher LDL-C levels. LDL-C concentrations with atherothrombosis was 1.93 mmol/L (IQR 1.48-2.47) versus 2.07 mmol/L (IQR 1.40-2.72, p=0.003) with atherosclerosis and guideline target value attainment 47.5% vs 38.6%, p<0.001, respectively. Conclusion Concerning age-adjusted sex-inequalities with higher LDL-C levels and lower guideline-target-value-attainment in women were found in both primary and secondary prevention. Within secondary prevention, a previous atherothrombotic event was associated with lower LDL-C levels and higher guideline-target-value-attainment.

Sex differences in management of LDL-cholesterol in patients with chronic coronary syndrome

Abstract Background Effective management of low-density lipoprotein cholesterol (LDL-C) is crucial for preventing recurrent cardiovascular (CV) events in patients with chronic coronary syndrome (CCS). Sex may impact the LDL-C management, by gender bias and/or sex-specific responses to pharmacological interventions. Purpose We examined sex-specific LDL-C management in CCS patients, assessing target achievement rates and their implications for CV outcomes. Methods In the international CLARIFY registry, we included 22,134 CCS patients with baseline LDL-C measurements. LDL-C levels were monitored annually over the 5-year follow-up period. Target LDL-C was set at 100 mg/dL, in line with prevailing recommendations at that time. Sex-specific differences in LDL-C were adjusted for age, geographical region and indication for lipid lowering drugs (stroke, MI, PAD). The primary endpoint was the incidence of MACE, defined as CV death or MI during the 5-year follow-up, evaluated using multivariable analysis adjusted for known predictors of recurrent CV events in CCS patients. Results Of 22,134 patients, 21.6% were women. Upon inclusion (6.5 ± 6.3 years after CCS diagnosis), women were more likely than men to have LDL-C levels above the recommended threshold (45.6% vs. 37.4%; aOR 1.47, 95%CI 1.38-1.58, p<0.001) and less likely to receive statin treatment (82.7% vs. 85.4%, p<0.001). Although women and men had comparable numbers of LDL-C measurements during follow-up, the discrepancies endured over the 5-year observation period, with women consistently showing lower likelihoods of achieving LDL-C targets at 1, 2, 3, 4, and 5 years post-inclusion (p<0.001 for all time points). Overall, women were less likely than men to have all available LDL-C concentrations within the target range (37.8% vs. 44.6%; aOR 0.70, 95% CI 0.64-0.76, p<0.001) and more likely to never reach the target LDL-C goal during follow-up (22.6% vs. 17.5%; aOR 1.43, 95% CI 1.32-1.55, p<0.001). Failing to achieve at least one LDL-C concentration below 100 mg/dL was associated with an increased risk of subsequent MACE (adjusted HR 1.57, 95%CI 1.38-1.77, p<0.001), with similar associations observed in both men (aHR 1.66, 95% CI 1.44-1.91, p<0.001) and women (aHR 1.31, 95% CI 1.01-1.70, p=0.05). Conclusion In patients with CCS, women consistently showed lower likelihood of reaching LDL-C targets throughout follow-up compared to men, even after adjusting for age, geographical region and other statin indications. Notably, women were more likely to have no LDL-C concentration within recommended range during follow-up, which is particularly concerning given its association with an increased risk of CV events. A contributing factor to this sex disparity in LDL-C control is women's lower likelihood of receiving lipid-lowering drugs than men. These results highlight the need for tailored interventions to address sex-related disparities in LDL-C management and improve cardiovascular outcomes in CCS patients.

Patient reported outcomes, control of hypertension and dyslipidemia: results of two epidemiological studies in Romania, conducted during pandemia (Snapshot-1) and post-pandemic (Snapshot-2)

Abstract Background Coexistence of hypertension and dyslipidemia is commonly found in daily practice. Patient reported outcomes (PRO) are increasingly used to guide clinical decision-making, as well as public reporting of health system performance. Purpose To assess patient reported outcomes (PRO: socio-economic factors, depression level, and treatment adherence) and control of blood pressure (BP) and LDL-cholesterol (LDL-C) during pandemia and in the post-pandemic period. Methods Two real-world, cross-sectional, multicentre, observational studies, with a similar design, were conducted in Romania during pandemia, in June 2021 (SnapShot-1), and post-pandemic, in June 2022 (SnapShot-2). They included 5004 consecutive outpatients diagnosed with both hypertension and dyslipidemia, addressing cardiologists, diabetologists, and general practitioners: 2469 in SnapShot-1 and 2535 in SnapShot-2. Patients completed a three-part questionnaire including: (1) questions on socio-economic factors; (2) Patient Health Questionnaire (PHQ-9) (Depression scale); and (3) Hill-Bone Medication Adherence Scale (HBMAS) for hypertension and dyslipidemia. Results Characteristics of patients were similar between studies: 65.0±10.0 years and 40.9% men (SnapShot-1), 63.6±10.7 years and 43.3% men (SnapShot-2). Most of the patients declared themselves as "adherent" to the prescribed treatment: 91.8% (SnapShot-1) and 93.0% (SnapShot-2) adherent to antihypertensive treatment; 89.6% (SnapShot-1) and 90.9% (SnapShot-2) adherent to lipid lowering treatment. Socio-economic factors were similar between studies, except education, with higher education rates in SnapShot-2 (Table 1). Compared to SnapShot-1, depression scores evaluated by PHQ-9 scale were lower in SnapShot-2, conducted post-pandemic: 5.9±4.9 for SnapShot-1, suggesting a "mild" depression level, vs. 4.9±4.6 for SnapShot-2, which is below the "mild" depression threshold. Similarly, the adherence scores measured by HBMAS were lower in SnapShot-1 vs. SnapShot-2: 33.8±3.0 vs. 34.0±2.9 for antihypertensive medication, and 33.5±3.5 vs. 33.7±3.4 for lipid lowering treatment (Table 2). Conclusion Data collected from two large epidemiological studies in Romania showed an improvement of post-pandemic depression rates, as well as an improvement of adherence scores. Use of PRO assessment in routine clinical practice could support identification of patients on risk for uncontrolled BP or LDL-C, in need of more intense medical care.

Recent trends of low-density lipoprotein cholesterol control and lipid-lowering therapy in patients with atherosclerotic cardiovascular disease in Taiwan: 2015–2020

ObjectiveThis study aimd to assess recent trends in the control of low-density lipoprotein cholesterol (LDL-C) and the utilization of lipid-lowering drugs (LLD) among patients with atherosclerotic cardiovascular disease (ASCVD) in Taiwan. MethodsPatients with ASCVD and without a history of hemorrhagic stroke were identified from the Taiwanese Secondary Prevention for patients with AtheRosCLErotic disease (T-SPARCLE) Registry. ASCVD patients were stratified into four categories: those who ever had acute coronary syndrome (ACS), those who underwent percutaneous coronary intervention or coronary artery bypass grafting (PCI/CABG) without ACS, those who ever had an ischemic stroke (IS) without ACS or PCI/CABG, and other ASCVD cases. We assessed their latest recorded LDL-C levels for the periods 2015–16, 2017–18, and 2019–20. LLD therapy patterns were presented as monotherapy, dual therapy, or combination therapy of three or more drugs, with statin use classified by intensity. ResultsWe identified 3831 ASCVD patients in 2015–16, 3531 in 2017–18, and 1231 in 2019–20. LLD utilization rose from 58.4% in 2015–16 to 73.2% in 2019–20. The proportions of patients achieving LDL-C goals in 2015–16, 2017–18, and 2019–20 were 21.5%, 25.8%, and 33.3% in the ACS cohort (goal <70 mg/dL); 20.4%, 26.1%, and 39.0% in the PCI/CABG cohort (goal <70 mg/dL); 54.4%, 58.5%, and 58.9% in the IS cohort (goal <100 mg/dL); and 60.0%, 65.5%, and 67.0% in the other ASCVD cohort (goal <100 mg/dL), respectively. Over half of the patients were prescribed moderate-intensity statins. Statin use, age, history of diabetes mellitus, and hypertension were important factors for attaining LDL-C goal in ACS patients. ConclusionDespite improvements in LDL-C management observed over recent years, significant gaps remain in guideline adherence, especially for patients with ACS or PCI/CABG in Taiwan, with over 60% not meeting LDL-C targets. Intensifying efforts to align clinical practice with guidelines are imperative.

Inflammatory Trajectory of Type 2 Diabetes: Novel Opportunities for Early and Late Treatment.

Low-grade inflammation (LGI) represents a key driver of type 2 diabetes (T2D) and its associated cardiovascular diseases (CVDs). Indeed, inflammatory markers such as hs-CRP and IL-6 predict the development of T2D and its complications, suggesting that LGI already increases before T2D diagnosis and remains elevated even after treatment. Overnutrition, unhealthy diets, physical inactivity, obesity, and aging are all recognized triggers of LGI, promoting insulin resistance and sustaining the pathogenesis of T2D. Once developed, and even before frank appearance, people with T2D undergo a pathological metabolic remodeling, with an alteration of multiple CVD risk factors, i.e., glycemia, lipids, blood pressure, and renal function. In turn, such variables foster a range of inflammatory pathways and mechanisms, e.g., immune cell stimulation, the accrual of senescent cells, long-lasting epigenetic changes, and trained immunity, which are held to chronically fuel LGI at the systemic and tissue levels. Targeting of CVD risk factors partially ameliorates LGI. However, some long-lasting inflammatory pathways are unaffected by common therapies, and LGI burden is still increased in many T2D patients, a phenomenon possibly underlying the residual inflammatory risk (i.e., having hs-CRP > 2 mg/dL despite optimal LDL cholesterol control). On the other hand, selected disease-modifying drugs, e.g., GLP-1RA, seem to also act on the pathogenesis of T2D, curbing the inflammatory trajectory of the disease and possibly preventing it if introduced early. In addition, selected trials demonstrated the potential of canonical anti-inflammatory therapies in reducing the rate of CVDs in patients with this condition or at high risk for it, many of whom had T2D. Since colchicine, an inhibitor of immune cell activation, is now approved for the prevention of CVDs, it might be worth exploring a possible therapeutic paradigm to identify subjects with T2D and an increased LGI burden to treat them with this drug. Upcoming studies will reveal whether disease-modifying drugs reverse early T2D by suppressing sources of LGI and whether colchicine has a broad benefit in people with this condition.

8261 Achievement of Diabetes Treatment Goals in Mexico from 2016 to 2022

Abstract Disclosure: D. Ramirez Garcia: None. C.A. Fermin Martinez: None. P.N. Mendez Labra: None. N.E. Antonio Villa: None. J.A. Seiglie: None. O.Y. Bello-Chavolla: None. Background: Optimal diabetes care involves achieving goals with treatment in key metabolic parameters including HbA1c, blood pressure (BP), low density lipoprotein cholesterol (LDL-C) levels, and smoking cessation. Evaluation of diabetes care in Mexico has been incomplete, with previous studies focusing primarily on glycemic control, but not on a comprehensive analysis of combined treatment targets. Objective: To estimate achievement of diabetes treatment goals (HbA1c [A], BP [B], LDL-C [C], smoking cessation [N], and combined targets [AB, BC, AC, ABC, ABCN]) using data from nationally representative surveys from 2016-2022 among individuals with diagnosed diabetes in Mexico. Methods: We analyzed serial cross-sectional National Health and Nutrition Surveys from 2016-2022. A total of 2,689 adults with diagnosed diabetes ≥20 years were identified amongst 21,248 adults ≥20 years. Weighted prevalence estimates were obtained for glycemic control (HbA1c &amp;lt;7% in those &amp;lt;65 years, and &amp;lt;7.5% in those ≥65 years), BP control (&amp;lt;130/80 mmHg), LDL-C control (&amp;lt;70 mg/dL), smoking cessation, and combined targets. We also fitted logistic regression models to estimate the odds of achieving treatment targets according to age, sex, educational level, indigenous identity, and survey cycle. Results: In 2022, the prevalence of HbA1c, BP, and LDL-C control among individuals with diagnosed diabetes in Mexico was 41.2% (95% CI 30.5-52.0%), 46.0% (95% CI 36.5-55.5%), and 17% (95% CI 10.2-25.2%), respectively. Non-smoking prevalence was 92.4% (95% CI 88.6-96.2%). Combined target achievement was low, with a prevalence of 10.8% (95%CI 6.2-15.5%) for BC and 4% (95% CI 1.7-6.3%) for ABCN. The proportion of goal achievement was relatively stable across 2016-2022 for every parameter analyzed, except for LDL-C. LDL-C had the lowest proportion of control across all cycles, although a gradual increase was observed: 8.1% (95% CI 4-12.3%) in 2016 to 17% (95% CI 10.2-25.2%) in 2022. The increase in LDL-C control coincides with greater prevalence of statin use across survey cycles. Men had lower odds of achieving ABCN combined control (OR 0.49, 95%CI 0.45-0.54) than women. Similarly, compared with individuals &amp;lt;45 years, participants 45-64 years (OR 0.36, 95%CI 0.32-0.40) and ≥65 years (OR 0.41 95%CI 0.35-0.47) had lower odds of achieving composite control. Conclusions: Achievement of diabetes treatment goals in Mexico is suboptimal. Less than half of individuals with diagnosed diabetes achieve HbA1c or BP goals, less than a fifth achieve LDL-C control, and only 1 in 20 individuals achieve ABCN control. Greater efforts are needed to the improve the comprehensive care of individuals with diabetes in Mexico. Presentation: 6/3/2024

6954 Effect Of The SARS-CoV-2 Pandemic on Metabolic Control In Patients With Type 2 Diabetes: A 5-year Cohort Follow-Up

Abstract Disclosure: D.P. Morales Rodríguez: None. M. Romero Ibarguengoitia: None. A. Garza-Silva: None. A. Rivera-Cavazos: None. I. Fernandez-Chau: None. A. Cepeda Medina: None. A. Gonzalez-Cantú: None. The SARS-CoV-2 pandemic brought a radical shift in the healthcare system and a suboptimal care for vulnerable patients, such as those with Type 2 Diabetes Mellitus (T2DM). Thus, we compared the metabolic control of patients with T2DM before and throughout 3 years of the SARS-CoV-2 pandemic, described the type of consultations and trends in attendance in various specialties, and compared the number of medications prescribed to patients before and during the pandemic. We conducted a retrospective observational cohort study on steelworkers with T2DM from a hospital in northeastern Mexico, who were treated by a multidisciplinary team from 2018 to 2022. We analyzed HbA1C levels, fasting serum glucose (FGS), low-density lipoprotein cholesterol (LDLc), blood pressure (BP) values, microalbuminuria, attendance at consultations across different specialties, and the trend in medication usage. We analyzed 999 subjects, 516 (51.7%) males, with a mean age (SD) of 60.1 (12.7) years. A significant difference was found in the proportion of controlled patients based on HbA1C with 55.5% in 2018 and 70.7% in 2022 (p&amp;lt;0.001). There was an increase of FGS control from 13.8% in 2018 to 56.1% in 2022 (p&amp;lt;0.001). LDL cholesterol control exhibited a decrease from 62.1% in 2018 to 57% in 2022 (p&amp;lt;0.001). Proportion of patients with systolic BP control decreased from 82.7% in 2018 to 80.1% in 2022 (p&amp;lt;0.001). Diastolic BP control was 89.6% in 2018 with an increase to 91.4% in 2022 (p=0.01). Microalbuminuria based control, increased from 80.5% in 2018 to 89% in 2022 (p=0.002). Telephone consultations were introduced in 2020, with 899 (90%) patients using this modality at least once, leading to a 35.8% decrease of in-person consultations (n=541,54.2%) and reaching its lowest point in 2021 (n=2, 0.2%). Throughout the follow-up period, all patients had at least one annual consultation with an internist or geriatrician based on their age group. There was an increase of endocrinology consultations from 8.5% in 2018 to 12.1% in 2022 and in cardiology from 6.9% in 2018 to 10.3% in 2022 (&amp;lt;0.05). There was a rise in the prescription of oral hypoglycemic agents raging from 4.9% to 14.2% between 2018 and 2020, with SGLT2 inhibitors being the highest prescribed and a 2.5% decrease in the prescription of sulfonylureas between 2018 and 2020. Similarly, there was an increase in the prescription of long-acting insulin by 5.9% between 2018 and 2020. There was a higher proportion of patients with controlled glycemic and diastolic blood pressure targets during the SARS-CoV-2 pandemic, this can be attributed to patient’s access to telemedicine and a multidisciplinary team capable of providing an appropriate medication prescription for an optimized management and improvement in patient’s quality of life.

Real-World Exploration of LDL-Cholesterol Management in Patients with Atherosclerotic Cardiovascular Disease

BackgroundAlthough guidelines recommend low-density lipoprotein cholesterol (LDL-C) to be <70mg/dL in patients with atherosclerotic cardiovascular disease (ASCVD), the rate of achieving this goal remains suboptimal. We sought to understand real world contemporary practice patterns of LDL-C management in patients with ASCVD, and whether LDL-C testing influenced management across US health systems. MethodsA retrospective cohort study utilizing electronic medical record data from five health systems participating in the CardioHealth Alliance was performed on patients with an LDL-C measurement in 2021 and prior ASCVD. Multivariable regression modeling was used to determine the relationship of clinical factors with achievement of guideline directed LDL-C target. Changes in lipid lowering therapy (LLT) after LDL-C testing were also described. ResultsAmong 216,074 patients with ASCVD, 129,886 (60.1%) had uncontrolled LDL-C (i.e. ≥70 mg/dL). Compared with participants with controlled LDL-C (<70mg/dL), those with uncontrolled LDL-C were more frequently female (50.9% vs 35.1%), or Black (13.7% vs. 10.3%), and less commonly had coronary artery disease as the form of vascular disease (73.0% vs. 83.5% %), heart failure (21.3% vs. 29.1% %), diabetes (34.1% vs. 48.2%), atrial fibrillation (19.3% vs. 26.1%), or chronic kidney disease (25.1% vs. 32.2%). In multivariable analyses, the factors most strongly associated with failure to achieve LDL-C control were female sex (RR 1.13 [95% CI 1.12-1.14] p <0.001) and Black race (1.15 [1.14-1.17] p <0.001). Among the 53,957 (41.5%) of those with uncontrolled LDL-C ≥70 mg/dL not on lipid lowering therapy (LLT) at baseline, only 21% were initiated on any LLT within 6 months of the uncontrolled LDL-C value. ConclusionsWithin five diverse large health systems in the CardioHealth Alliance, more than half of the patients with ASCVD had uncontrolled LDL-C with significant disparities based on sex and race at baseline. The vast majority were not initiated on any lipid lowering therapy within 6 months of an elevated test result indicating persistent gaps in care that will likely worsen health inequities in outcomes. This highlights the urgent need for implementation efforts to improve equitable care.

The therapeutic effect of PCSK9 inhibitors on dyslipidemia: one-year follow up.

Despite the availability of statins and lifestyle modifications, many patients with Dyslipidemia struggle to achieve optimal low-density lipoprotein cholesterol (LDL-C) control. PCSK9 inhibitors offer a promising new therapeutic option with superior LDL-C lowering efficacy compared to statins. However, data on their real-world use, particularly in Iran, is limited. This study aims to address this gap by investigating the one-year effects of evolocumab on lipid profiles and potential cardiovascular outcomes in Iranian patients with Familial Hypercholesterolemia (FH).This single-center, prospective study evaluated evolocumab effectiveness in lowering LDL-C in 50 Iranian adults with FH. Participants with a documented LDL-C > 190 mg/dL on existing cholesterol medications (excluding PCSK9 inhibitors) and a clinical FH diagnosis was included. After baseline assessments (medical history, demographics, lipid profile), evolocumab was administered subcutaneously every two weeks for one year. Follow-up assessments at year one measured changes in LDL-C, high-density lipoprotein cholesterol (HDL-C), and triglycerides. The study enrolled 50 participants with an average age of 55 years old (range 35-80 years).Treatment with evolocumab led to significant improvements in lipid profiles at all follow-up points compared to baseline. On average, LDL-C levels decreased by 105.24 mg/dL, triglycerides decreased by 59.20 mg/dL, and HDL-C levels increased by a modest but significant 4.5 mg/dL after one year(p<0.001). Subgroup analysis revealed no statistically significant interactions between baseline demographics (age, sex, BMI) or lifestyle habits (smoking, alcohol) and changes in lipid levels(p>0.05). However, a significant interaction emerged between baseline lipid levels and their corresponding reductions, suggesting greater improvement in patients with higher baseline values(p<0.05). It is noteworthy that no new cardiovascular events were reported during the study period. This study demonstrates the effectiveness of evolocumab in improving lipid profiles in Iranian patients with FH. The observed reductions in LDL-C and triglycerides, along with a modest increase in HDL-C, suggest potential benefits for cardiovascular risk reduction. The absence of new cardiovascular events during the study is encouraging, but further research with larger and longer-term follow-up is needed to confirm these findings and assess the long-term safety and impact on quality of life.

Association Between Patient Sex and Familial Hypercholesterolemia and Long-Term Cardiovascular Risk Factor Management 5 Years After Acute Coronary Syndrome.

Long-term control of cardiovascular risk factors after acute coronary syndrome (ACS) is the cornerstone for preventing recurrence. We investigated the extent of cardiovascular risk factor management in males and females with and without familial hypercholesterolemia (FH) 5 years after ACS. We studied patients hospitalized for ACS between 2009 and 2017 in a Swiss multicenter prospective cohort study. FH was defined based on clinical criteria from the Dutch Lipid Clinic Network and Simon Broome definitions. Five years post-ACS, we assessed low-density lipoprotein-cholesterol (LDL-c) levels, lipid-lowering therapy (LLT), and other cardiovascular risk factors, comparing males to females with and without FH using generalized estimating equations. A total of 3139 patients were included; mean age was 61.4 years (SD, 12.1), 620 (19.8%) were female, and 747 (23.5%) had possible FH. Compared with males at 5-years post-ACS, females were more likely to not use statins (odds ratio, 1.61 [95% CI, 1.28-2.03]) and less likely to have combination LLT (odds ratio, 0.72 [95% CI, 0.55-0.93]), without difference between patients with FH and without FH. Females in both FH and non-FH groups less frequently reached LDL-c values ≤1.8 mmol/L (odds ratio, 0.78 [95% CI, 0.78-0.93]). Overall, patients with FH were more frequently on high-dose statins compared with patients without FH (51.0% versus 42.9%; P=0.001) and presented more frequently with a combination of 2 or more LLT compared with patients without FH (33.8% versus 17.7%; P<0.001), but less frequently reached LDL-c targets of ≤1.8 mmol/L (33.5% versus 44.3%; P<0.001) or ≤2.6 mmol/L (70.2% versus 78.1%; P=0.001). Five years after ACS, females had less intensive LLT and were less likely to reach target LDL-c levels than males, regardless of FH status. Males and females with FH had less optimal control of LDL-c despite more frequently taking high-dose statins or combination LLT compared with patients without FH. Long-term management of patients with ACS and FH, especially females, warrants optimization.

Study on the management effect of chronic disease intelligent information management platform in post percutaneous coronary intervention patients.

In 2019, approximately 330 million individuals in China were affected by cardiovascular diseases, with 11.4 million cases specifically attributed to coronary artery disease (CAD). A national public health report indicated that the mortality rate for CAD ranged from 121.59 to 130.14 per 100,000 individuals in 2019. The treatments for CAD include lifestyle changes, medications, percutaneous coronary intervention (PCI) and coronary artery bypass grafting. To investigate the management effect of a digital health program in patients with coronary artery disease (CAD) after percutaneous coronary intervention (PCI). This retrospective study compares blood pressure, blood glucose, low-density lipoprotein cholesterol (LDL-C), medication adherence, lifestyle modification, and readmission rate between digital health users and traditional follow-up in post-PCI CAD patients. In this study of 698 CAD patients, the 6-month readmission rate of all patients was 27.4%, with digital health users showing lower rates than those in traditional follow-up (22.6% vs. 32.1%, p= 0.005). Digital health users had significantly higher target achievements rates in blood pressure (79.7% vs. 54.7%, p< 0.001), blood glucose (98.9% vs. 82.5%, p< 0.001) and LDL-C level (71.3% vs. 52.7%, p< 0.001) at 6-month post-PCI. The digital health group had more patients adopting lifestyle changes, including quitting smoking, maintaining a healthy diet, and exercising regularly. In risk factor analysis, digital health utilization (OR = 0.60, 95%CI: 0.40-0.90, p= 0.014) and multivessel disease (double: OR = 1.72, 95%CI: 1.09-2.72, p= 0.02; triple: OR = 2.59, 95%CI: 1.61-4.17, p< 0.001) were independent predictors of CAD-related cardiovascular readmissions. Post-PCI patients using digital health platforms exhibited improved blood pressure, glucose, and LDL-C control, greater treatment adherence, enhanced lifestyle changes, and reduced six-month readmission rates versus those with traditional follow-up.

Efficacy and safety of bempedoic acid in acute coronary syndrome. Design of the clinical trial ES-BempeDACS

Introduction and objectivesOnly about 1 out of every 3 patients with acute myocardial infarction (AMI) achieve low-density lipoprotein cholesterol (LDL-C) values <55mg/dL in the first year. The present study aims to evaluate the impact of early intensive therapy on lipid control after an AMI. MethodsAn independent, prospective, pragmatic, controlled, randomized, open-label, evaluator-blinded clinical trial (PROBE design) will analyze the efficacy and safety of an oral lipid-lowering triple therapy: high-potency statin+bempedoic acid (BA) 180mg+ezetimibe (EZ) 10mg versus current European-based guidelines (high-potency statin±EZ 10mg), in AMI patients. LDL-C will be determined within the first 48hours. Patients with LDL-C ≥ 115mg/dL (without previous statin therapy), ≥ 100mg/dL (with previous low-potency or high-potency statin therapy at submaximal dose), or ≥ 70mg/dL (with previous high-potency statin therapy at high dose) will be randomly assigned 1:1 between 24 and 72hours post-AMI to the BA/EZ combination or to statin±EZ, without BA. The primary endpoint is the proportion of patients reaching LDL-C <55mg/dL at 8 weeks after treatment. ResultsThe results of this study will provide novel information for post-AMI LDL-C control by evaluating the usefulness of an early intensive lipid-lowering strategy based on triple oral therapy. ConclusionsEarly intensive lipid-lowering triple oral therapy vs the treatment recommended by current clinical practice guidelines could facilitate the achievement of optimal LDL-C levels in the first 2 months after AMI (a high-risk period).

Gender differences and hypercholesterolemia: real-world evidence from the study WECARE (Women Effective CArdiovascular Risk Evaluation)

Introduction: The therapeutic control of LDL-cholesterol is essential in cardiovascular prevention, as recommended by the recent guidelines. Objective: To evaluate gender differences in terms of demographic and clinical characteristics, treatment pattern, treatment adherence and healthcare costs in patients on lipid-lowering therapy, stratified by cardiovascular risk in the Italian real clinical practice. Methods: An observational analysis was conducted on the administrative databases of healthcare institutions, covering about 6.1 million health-assisted subjects. After inclusion of all patients on lipid-lowering therapy between January 2017 and June 2020, the population was investigated in the period before the first prescription of a lipid-lowering drug and followed-up for at least 12 months. Clinical and demographic variables were compared after stratification by gender and by cardiovascular risk (very high/high/other risk). The main outcome measures were treatment adherence and direct healthcare costs during follow-up. Results: Of the 684,829 patients with high/very high cardiovascular risk, 337,394 were men and 347,435 women, aged on average 69.3 years and 72.1 years, respectively (p &lt; 0.001). Men were characterised by a worse comorbidity profile. Regardless of cardiovascular risk, female subjects were associated with larger utilisation of low-potency statins and lower adherence (p &lt; 0.001). The annual healthcare costs per patient during follow-up were higher in men than in women (p &lt; 0.001). Conclusions: The results highlighted larger utilisation of low-potency statins, a lower adherence and a milder comorbidity profile in women, the latter feasibly explaining the reduced healthcare costs compared to men.

Associations and attributable burden between risk factors and all-cause and cause-specific mortality at different ages in patients with hypertension.

It remains unclear the age-specific associations of risk factors with deaths and mortality burden attributable across age. In a territory-wide retrospective cohort, 1,012,228 adults with hypertension were identified. Comorbidities including diabetes, chronic kidney disease (CKD), cardiovascular disease (CVD), heart failure, and cancer, and risk factors including current smoking and suboptimal control of blood pressure (BP), glucose and low-density lipoprotein cholesterol were defined. Associations of comorbidities/risk factors with all-cause and cause-specific mortality across age groups (18-54, 55-64, 65-74, and ≥75 years) were assessed. Population attributable fractions were also quantified. During a median follow-up of 10.7 years, 244,268 (24.1%) patients died, with pneumonia (7.2%), cancer (5.1%), and CVD (4.2%) being the leading causes. Despite increasing deaths with age, relative risk of mortality related to comorbidities/risk factors decreased with age; similar patterns were found for cause-specific mortality. The assessed risk factors accounted for 24.0% (95% CI 22.5%, 25.4%) deaths, with highest proportion in the youngest group (33.5% [28.1%, 38.5%] in 18-54 years vs 19.4% [17.0%, 21.6%] in ≥75 years). For mortality burden, CKD was the overall leading risk factor (12.7% [12.4%, 12.9%]) with higher proportions in older patients (11.1-13.1% in ≥65 years), while diabetes was the leading risk factor in younger patients (15.9-13.5% in 18-54 years). The association of comorbidities or risk factors with mortality is stronger in younger patients with hypertension, despite lower absolute mortality in young patients than in the elderly. Leading risk factors differed across age, highlighting the importance of targeted and precise risk management.

Prescription of lipid-lowering therapy, LDLc control, and risk of MACE in patients after ST-elevation myocardial infarction in Mexico

Abstract Funding Acknowledgements None. Background/Introduction Optimal control of low-density lipoprotein cholesterol (LDLc) has been demonstrated to reduce cardiovascular event rates after ST-elevation myocardial infarction (STEMI). However, real-world data shows that a low proportion of patients achieve LDLc targets. Furthermore, the association of LDLc levels and major cardiovascular adverse events (MACE) in post-STEMI patients is limited in developing countries. Purpose In this study, we aimed to assess the prescription patterns of lipid-lowering therapies, LDLc control, and their impact on the risk of MACE after STEMI in Mexico. Methods We conducted a prospective observational study of patients with STEMI. LDLc levels and prescriptions of lipid-lowering therapy were assessed during the first scheduled visit following STEMI hospital discharge. LDLc control was determined in accordance with the 2023 European Society of Cardiology Acute Coronary Syndrome Guidelines, which recommend achieving LDLc levels below 55 mg/dL for secondary prevention. Patients were categorized as controlled (if LDLc &amp;lt;55 mg/dL) and not controlled (if LDLc &amp;gt;55 mg/dL) and were followed for a median of 4.5 years to evaluate the rate of MACE, including cardiovascular death, cardiogenic shock, recurrent MI, and heart failure. Results We included 447 patients with a mean age of 57.87 (± 10.5 years), predominantly male (84.5%). Hypertension (43.8%), smoking (41.1%), type 2 diabetes mellitus (33.5%), obesity (26.6%), and dyslipidemia (21.4%) were highly prevalent. The median LDLc level in the total population was 65.4 mg/dL (IQR 49.2- 87.7). Among these, 34% (152) were considered controlled, while 66% (295) were not. Baseline clinical characteristics did not significantly differ among the groups. Prescription of high-intensity statins reached 94.7%, and ezetimibe and PCSK-9i were used in 1.8% and 0.4% of cases, respectively. We observed no statistically significant difference (Hazard ratio: 1.03, 95% confidence interval 0.74-1.73) in the rate of MACE based on LDLc control (Fig.1). The risk of MACE was also not different based on the use of high-intensity statins. Conclusions In this real-world study of patients post-STEMI, LDLc control was achieved in just one-third of the population. While the prescription of high-intensity statins was high, combination therapy was low. We did not observe a statistically significant association with an increased long-term risk of MACE; however, we noted a higher rate of events compared with other series.

Real-world evidence evaluation of LDL-C among hospitalized patients: a population-based observational study in the timeframe 2021-2022

Aims. European registries and retrospective cohorts highlighted the lack of low-density lipoprotein-cholesterol (LDL-C) goal achievement in many very high-risk patients. Hospitalized patients are often frail, and frailty is associated with all-cause mortality and cardiovascular mortality. Aim of this study is to evaluate LDL-C levels in a Real-World setting of inpatients, identify cardiovascular risk categories and highlight treatment gaps in the implementation of LDL-C control. Methods. This retrospective, observational study included all the adult patients admitted at an Italian hospital between 2021-2022 and with LDL-C values available during hospitalization. Disease-related real-world data were collected from Hospital Information Systems using automated data extraction strategies and through the implementation of a patient-centered data repository (the Dyslipidemia Data Mart). Assessment of cardiovascular risk profiles, LDL-C target achievement according to the 2019 ESC/EAS guidelines and lipid-lowering therapies (LLT) use were performed. Results. 13,834 patients were included: 17.15%, 13.72%, 16.82% and 49.76% were low (L), moderate (M), high (H) and very high-risk (VH) patients, respectively. The percentage of in-target patients was progressively lower moving towards worse categories (78.79% in L, 58.38% in M, 33.3% in H and 21.37% in VH). Among LLT treated patients in VH category, in-target are 28.48%; 47.6.% in H, 69.12% in M and 68.47% in L. The impact of monotherapies and combination therapies on target achievement was also analyzed. Conclusions. This study depicts LDL-C control among an entire population of inpatients, highlighting relevant gaps especially in VH category. Future efforts must aim to reduce the cardiovascular risk of these subjects.
