The Emerging Potential of Apolipoprotein C-III Inhibition for ASCVD Prevention: A State-of-the-Art Review.

Multiple agents are being developed that inhibit apolipoprotein (apo) C-III. This state-of-the-art review examines their potential for atherosclerotic cardiovascular disease (ASCVD) risk reduction. Apo C-III, an apolipoprotein on the surface of triglyceride-rich lipoproteins (TRLs), impairs clearance of TRLs through both lipoprotein lipase dependent and independent pathways, thereby resulting in increased concentrations of triglycerides. Apo C-III has also been shown to have pro-atherogenic effects when bound to high-density lipoprotein (HDL) particles. Classical and genetic epidemiology studies provide support for the concept that apo C-III is associated with an increased risk of ASCVD events. Drug efficacy of agents that silence APOC3 mRNA has been studied in populations with varying hypertriglyceridemia severity, including those with familial chylomicronemia syndrome, multifactorial chylomicronemia syndrome/severe hypertriglyceridemia, and mixed hyperlipidemia. Randomized controlled trials have reported significant reductions in TG and non-HDL cholesterol levels among these patients treated with APOC3 inhibitors. Upcoming clinical outcomes trials seek to establish a role for APOC3 inhibitors to reduce risk of ASCVD.

Abstract 4120312: Patient Perspectives on Barriers and Facilitators to Familial Hypercholesterolemia Cascade Testing Through the Lens of the Socio-Ecological Model

Background: Low uptake of Familial Hypercholesterolemia (FH) cascade testing, the stepwise identification of at-risk relatives, leads to missed opportunities for atherosclerotic cardiovascular disease (ASCVD) prevention. The IMPACT-FH study offered strategies (packet, chatbot, and direct contact) to support FH cascade testing. Hypothesis: We hypothesized that IMPACT-FH strategies would facilitate cascade testing uptake and overcome persistent barriers to cascade testing. Aim: We aimed to understand barriers and facilitators to FH cascade testing in the context of the socio-ecological model (SEM) which provides a framework to examine the interconnected influences of intrapersonal, interpersonal, institutional, community, and policy levels. Methods: Semi-structured interviews were conducted with IMPACT-FH study participants. The SEM informed qualitative analysis to identify barriers and facilitators to FH cascade testing. Results: A total of 15 FH probands (initial family member tested) and 12 relatives were interviewed, of whom the majority (59%) were female with an average age of 55.7 years. All relatives completed cascade testing. At the interpersonal level, probands reported that relatives’ attitudes about high cholesterol, including seriousness and treatability, were a barrier or facilitator to cascade testing. Probands explained how relatives’ beliefs were informed by interactions with their clinicians and societal beliefs about cholesterol (i.e., medication stigma). Interpersonally, probands described challenges overcoming relatives’ beliefs and a reluctance to encourage relatives to complete testing despite the availability of novel strategies. Probands and relatives reported that insurance policies and concerns about testing costs informed cascade testing decision-making. Institutional strategies to provide low-cost testing and cost transparency were described as facilitators. Variable access to clinicians with genetics expertise and licensure laws were described as barriers by out-of-state relatives. Probands and relatives agreed that strategies providing direct access genetics expertise (i.e., direct contact, chatbot) helped address these barriers. Conclusion: The IMPACT-FH study ameliorated barriers at higher levels of the SEM related to access to genetics expertise and cost. Intra- and interpersonal barriers remained challenging to overcome. To improve FH detection and ASCVD prevention, it is important to address barriers at all levels of the SEM.

Abstract 4112853: Trends in Statin Use for the Secondary Prevention of Atherosclerotic Cardiovascular Disease among U.S. Adults by Age, 1999-2020

Background: Current research focusing on trends in statin medication usage, particularly for different age groups, is limited. This study explored the change trends in statin usage from 1999 to 2020, with a specific focus on different age groups. Methods: Utilizing data from the National Health and Nutrition Examination Survey spanning the period from 1999 to 2020, our study included individuals aged 18 years and older diagnosed with atherosclerotic cardiovascular disease (ASCVD). Results: In the 18-44 years age group, usage changed from 18.34% (95% CI, 0.18 to 36.50) in 1999 to 16.63% (95% CI, 0.36 to 32.91) in 2020 (linear P value = 0.540, quadratic P value = 0.610) (Figure 1). For individuals aged 45-64 years, usage increased from 39.33% (95% CI, 29.62 to 49.05) in 1999 to 54.97% (95% CI, 47.10 to 662.83) in 2020 (linear P value < 0.001, quadratic P value = 0.777) (Figure 1). In the group aged 65 years and older, usage increased from 35.17% (95% CI, 29.57 to 40.77) in 1999 to 60.62% (95% CI, 55.73 to 65.51) in 2010, and further to 68.62% (95% CI, 63.65 to 73.60) in 2020 (quadratic P value < 0.001) (Figure 1). There was an interaction effect between statin usage trends and age (P for interaction <0.001) (Figure 1). Conclusion: Overall, current health policies are effective for the use of statins for the secondary prevention of ASCVD. However, there was almost no improvement in statin usage within the 18-44 years age group. This highlights the need for greater focus on young ASCVD patients. Therefore, additional research is needed on statin use among young people.

Abstract 4137570: Atherosclerotic Cardiovascular Disease Risks in Children: An electronic health record data analytics approach

Background and Aims: There is little data on atherosclerotic cardiovascular disease (ASCVD) risk conditions, factors, and tiers in the pediatric population. This study aimed to develop and validate electronic health record (EHR) data analytic algorithms to attain the prevalence of 24 risk conditions, 7 factors, and 4 tiers in children in a rural community. Methods: This study included all the 495,902 subjects from 0 to 18 years at the Geisinger Medical Center from 2004 to 2022. The demographic and clinical data were collected using ICD-10 codes, clinical and laboratory data, and a dual-coded computational algorithm was developed based on the AHA guideline to derive the ASCVD risk conditions, factors, and tiers. To validate the EHR algorithms, the algorithm (rater 1) and a clinician (rater 2) extracted and analyzed the data from 40 randomly selected subjects from this cohort. Kendall’s coefficient of concordance (W) and Gwet’s agreement coefficient were used to evaluate algorithm and clinician agreement within the ASCVD tiers, conditions and factors, respectively. Results: High concordance was observed between algorithmic and clinician raters for risk tiers (W=80%), conditions (80-97%), and factors (49% for blood pressure, and 92% to 97% for the rest of the risk factors). In this cohort, the median age was 3.9 years, 51.0% were male, 80.6% were Non-Hispanic/Latino, and 88.1% were White. Overall, 15.5% (N = 76,945) were at-risk, 7.0% (N = 34,530) at moderate risk, and 4.2% (N = 20,761) at high risk for ASCVD, respectively. The most prevalent risk conditions were obesity (9.1%, N = 45,074), chronic inflammatory conditions (6.8%, N = 33,685), severe obesity (2.7%, N = 13,442), insulin resistance with comorbidities (2.7%, N = 13,397), and hypertension (2.1%, N = 10,436). The most prevalent risk factors were elevated BMI (27.4%, N = 135,904), blood pressure (12.5%, N = 62,015), and fasting lipid profile (8.7%, N = 43,100). Conclusion: Our EHR data analytics algorithm is in high agreement with the clinician rater. The high, moderate, and at-risk ASCVD risk tiers are prevalent in a large contemporary pediatric cohort at Geisinger. Both ASCVD risk conditions and factors are also prevalent, especially obesity, diabetes, hypertension, and hyperlipidemia. These findings suggest the further application and refinement of these algorithms to design innovative approaches for ASCVD risk reduction and prevention in children.

Gene-Based Targeting for Treatment of Hypercholesterolemia and Prevention of Atherosclerotic Cardiovascular Disease

Familial hypercholesterolemia, characterized by high levels of LDL cholesterol is a monogenic metabolic disorder linked to atherosclerotic cardiovascular disease. Several genetic mutations in genes such as LDLR and PSK9 are thought to cause familial hypercholesterolemia. This ultimately causes dysfunction of the LDLR pathway, increasing circulating LDL levels. Current treatment revolves around decreasing LDL cholesterol levels in the blood. Statins are the current gold standard while sterol absorption inhibitors (ezetimibe) and PCSK9 inhibitors (evolocumab) are either used as primary treatment in individuals with statin intolerance, or supplementary treatment otherwise. However, CRISPR-Cas9 offers an upstream therapeutic intervention, inducing mutations in pathogenic genes (such as LDLR) to upregulate or downregulate gene expression and subsequently reduce LDL cholesterol levels. This technology thus has great potential as a two-fold treatment option, offering an effective solution for familial hypercholesterolemia, while simultaneously diminishing the risk of atherosclerotic cardiovascular disease. A limitation to current research exists in the sole analysis of monogenic factors in genetic screening, thus polygenic, multifactorial analyses are required to assess more holistic treatment plans. Furthermore, there exist current limitations to CRISPR-Cas9 including ethical limitations and social considerations revolving around the perpetuation of social inequities through technology necessitating future research on global health policies.

Adding traditional and emerging biomarkers for risk assessment in secondary prevention: A prospective cohort study of 20,656 patients with cardiovascular disease.

This study aims to explore whether conventional and emerging biomarkers could improve risk discrimination and calibration in secondary prevention of recurrent atherosclerotic cardiovascular disease (ASCVD), based on a model using predictors from SMART2. In a cohort of 20,658 UK Biobank participants with medical history of ASCVD, we analysed any improvement in C indices and net reclassification index (NRI) for future ASCVD events, following addition of LP-a, ApoB, cystatin C, HbA1c, GGT, AST, ALT, and ALP, to a model with predictors used in SMART2 for the outcome of recurrent major cardiovascular event. We also examined any improvement in C indices and NRIs replacing creatinine based estimated glomerular filtration rate (eGFR) with cystatin C based estimates. Calibration plots between different models were also compared. Compared with the baseline model (C index=0.663), modest increment in C indices were observed when adding HbA1c (ΔC=0.0064, p<0.001), cystatin C (ΔC=0.0037, p<0.001), GGT (ΔC=0.0023, p<0.001), AST (ΔC= 0.0007, p<0.005) or ALP (ΔC=0.0010, p<0.001) or replacing eGFRCr with eGFRCysC (ΔC=0.0036, p<0.001) or eGFRCr-CysC (ΔC=0.00336, p<0.001). Similarly, the strongest improvements in NRI were observed with the addition of HbA1c (NRI=0.014), or cystatin C (NRI= 0.006) or replacing eGFRCr with eGFRCr-CysC (NRI=0.001) or eGFRCysC (NRI=0.002). There was no evidence that adding biomarkers modify calibration. Adding several biomarkers, most notably cystatin C and HbA1c, but not LP-a, in a model using SMART2 predictors modestly improved discrimination.

Quality of care for secondary cardiovascular disease prevention in 2009–2017: population-wide cohort study of antiplatelet therapy use in Scotland

BackgroundAntiplatelet therapy (APT) can substantially reduce the risk of further vascular events in individuals with established atherosclerotic cardiovascular disease (ASCVD). However, knowledge regarding the extent and determinants of APT use...

Rethinking atherosclerotic cardiovascular disease prevention in the era of expanding therapies: could plaque stabilization reduce the need for lifelong treatments and polypharmacy?

This review examines current evidence on pharmacologically induced plaque stabilization in the context of a growing range of new therapies. It explores the potential for a paradigm shift in atherosclerotic cardiovascular disease (ASCVD) prevention, where treatments may not need to be lifelong to achieve lasting benefits. Since 2015, over 14 novel therapies have been introduced, each shown to reduce ASCVD risk when added to standard care with statins and aspirin. More than 80% of ischemic heart disease patients are now eligible for one or more of these treatments, increasing the risk of polypharmacy, treatment burden, and adverse side effects. As more therapies become available, this challenge is expected to grow. Many of these treatments have demonstrated plaque regression and stabilization, as evidenced by both intravascular ultrasound and computed tomography angiography, which likely explains much of their efficacy. The increasing number of novel therapies presents challenges in preventing ASCVD without leading to lifelong polypharmacy and increased patient burden. Since many of these drugs act through plaque stabilization, a new approach may be feasible - using these treatments for shorter durations to induce plaque regression, followed by less intensive maintenance therapies to preserve stability. This approach warrants further investigation in future studies.

Association between colchicine use and adverse cardiovascular events in patients with gout: a nationwide nested case-control study.

The association between colchicine use and the primary prevention of atherosclerotic cardiovascular disease (ASCVD) remains unknown. This study aimed to explore the association between colchicine use and new development of ASCVD and ASCVD-related mortality in patients with incident gout. This nested case-control study utilized the nation-wide claims database of the Korean National Health Insurance System. Patients without a history of ASCVD who developed incident gout and were newly started on allopurinol as first-line therapy between 2011 and 2016 were initially screened. Individuals who experienced ASCVD event or ASCVD-related mortality during the follow-up period were matched with four controls for age, sex, income, residential area, co-morbidities, and medications. The main exposure was colchicine use, assessed by 1) the cumulative defined daily doses (cDDDs) and 2) the cumulative duration. For secondary analyses, the risk of ASCVD events and ASCVD-related mortality were examined, separately. Overall, 9,346 patients with ASCVD event or ASCVD-related mortality were matched with 35 070 controls. The patient population was predominantly male. Compared with non-users, a curvilinear relationship between higher cDDDs of colchicine and the odds of ASCVD event was observed; the odds ratios (95% confidence interval) were were 1.09 (1.04-1.15) for <90 cDDDs, 1.20 (1.07-1.33) for 80-179 cDDDs, and 1.21 (1.09-1.35) for ≥180 cDDDs. This association was similarly observed for ASCVD events and ASCVD-related mortality, respectively. Colchicine use was associated with an increased risk of ASCVD in patients with newly diagnosed gout who did not have a prior history of ASCVD.

Financial resources, access to care, and quality of care mediate racial disparities in statin usage for secondary prevention.

There are disparities in statin therapy for the secondary prevention of atherosclerotic cardiovascular disease (ASCVD). The role of structural racism in this disparity has not been examined. This is a cross-sectional study of participants with ASCVD in the Medical Expenditure Panel Survey from 2014-2017. Mediation analysis is utilized to estimate the direct effect of race and indirect effect of financial resources, access to care, and quality of care on statin usage. The proportion of participants using statins by race/ethnicity were 58.5% for non-Hispanic Whites, 45% for Hispanics, 48.6% for Blacks, 61.6% for Asians, and 46.8% for Others. Statin usage was lower for Hispanics (OR = 0.79, 95% confidence interval [0.65-0.96]) and Blacks (OR = 0.80 [0.66-0.95]) compared to Whites. Hispanic, Black, and Other participants with the same financial resources, access to care, and quality of care as White participants did not have significantly different statin usage compared to White participants (Hispanic: OR = 0.98 [0.79-1.13]; Black (OR = 0.88 [0.76-1.06], Other: OR 0.76, 95% CI [0.56-1.15]). Hispanic, Black, and Other participants had significantly lower statin usage than subjects of the same race but with financial resources, access to care, and quality of care observed in White subjects (Hispanic: OR = 0.83 [0.83-0.92]; Black: OR = 0.91[0.88-0.94]; Other: OR = 0.92 [0.87-0.98]). The indirect effect of race and ethnicity on statin therapy are significant but the direct effect of race and ethnicity on statin therapy are insignificant among Blacks and Hispanics compared to non-Hispanic Whites. This suggests that racial disparities in statin therapy are mediated through inequitably distributed resources, suggestive of the impact of structural racism.

Diabetes Risk Factors in People With HIV Receiving Pitavastatin Versus Placebo for Cardiovascular Disease Prevention : A Randomized Trial.

REPRIEVE (Randomized Trial to Prevent Vascular Events in HIV) led to new guidelines for statin use among people with HIV (PWH) with low to moderate risk for atherosclerotic cardiovascular disease (ASCVD). Little is known about the natural history of diabetes mellitus (DM) or mechanisms contributing to statin effects on DM among this population. To determine the contribution of known DM risk factors to excess risk for DM with pitavastatin in REPRIEVE. Phase 3, primary ASCVD prevention trial over a median of 5.6 years of follow-up. (ClinicalTrials.gov: NCT02344290). Global, multicenter trial. 7731 PWH aged 40 to 75 years with low to moderate ASCVD risk (by the pooled cohort equations from the American College of Cardiology and American Heart Association) without DM at study entry. Random 1:1 assignment to pitavastatin, 4 mg daily, or placebo. New-onset DM was determined at each visit by clinical diagnosis requiring initiation of medication treatment for DM. The incidence of new-onset DM was assessed in relation to predefined demographic and metabolic risk factors, stratified by treatment group. Treatment effects of pitavastatin on progression to new DM in key subgroups were determined. Participants with at least 3 DM risk factors (vs. no risk factors) had increased risk for DM in each treatment group (incidence rate, 3.24 per 100 person-years [PY] vs. 0.34 per 100 PY [pitavastatin] and 2.66 per 100 PY vs. 0.27 per 100 PY [placebo]). The incidence of DM was highest in South Asia. In adjusted analyses, high body mass index, prediabetes, and metabolic syndrome components were strongly associated with new-onset DM (all P < 0.005). Pitavastatin was the only statin assessed; DM was assessed clinically. Metabolic risk factors, including prediabetes and obesity, contributed to new-onset DM in statin- and placebo-treated participants. A clinically significant effect of pitavastatin on DM was seen primarily among those with multiple risk factors for DM at entry. Strategies targeting key metabolic risk factors, like obesity and prediabetes, may help protect against DM among PWH. National Heart, Lung, and Blood Institute of the National Institutes of Health.

Serum Lipoprotein(a) Levels and Their Association with Atherosclerotic Cardiovascular Disease in Japan.

To investigate the distribution of lipoprotein(a) (Lp(a)) and its association with atherosclerotic cardiovascular disease (ASCVD) in Japanese patients at high risk for ASCVD using a health insurance database. Between July 2013 and June 2021, patients eligible for ASCVD prevention according to the 2017 Japan Atherosclerosis Society (JAS) guidelines with documented Lp(a) test results were extracted from the Medical Data Vision claims database and divided into three groups: primary prevention high-risk (Group I), secondary prevention (Group II) and secondary prevention high-risk (Group III). Data on lipid levels, cardiovascular morbidity risk factors and lipid-lowering treatments were extracted. Of 700,580 patients with documented low-density lipoprotein cholesterol (LDL-C), 2,967 (0.42%) were tested for Lp(a). In 2,170 eligible patients, the median [interquartile range] serum concentration of Lp(a) was 13.9 [7.5-24.6] mg/dL, with 151 patients (7.0%) above the recommended risk threshold of ≥ 50 mg/dL. Lp(a) levels increased with risk across all prevention groups. Being in the highest Lp(a) quintile (Q5) was associated with an increased frequency of ASCVD (28.9% versus 18.9% in the lowest quintile (Q1) for unstable angina; 18.7% versus 10.1% for myocardial infarction; 27.9% versus 17.0% for ischemic stroke). In the secondary prevention groups, the proportion of patients meeting an LDL-C target of ＜70 mg/dL decreased from 30.2% in Q1 to 19.0% in Q5 for Group II and from 32.9% to 16.3% for Group III. Despite a high prevalence of Lp(a) ≥ 50mg/dL in Japanese patients at high risk for ASCVD, it found that the Lp(a) testing rate was very low.

Impact of Remnant Cholesterol on Cardiovascular Risk in Diabetes.

Individuals with diabetes face increased risk of atherosclerotic cardiovascular disease (ASCVD), in part due to hyperlipidemia. Even after LDL cholesterol-lowering, residual ASCVD risk persists, part of which may be attributed to elevated remnant cholesterol. We describe the impact of elevated remnant cholesterol on ASCVD risk in diabetes. Preclinical, observational, and Mendelian randomization studies robustly suggest that elevated remnant cholesterol causally increases risk of ASCVD, suggesting remnant cholesterol could be a treatment target. However, the results of recent clinical trials of omega-3 fatty acids and fibrates, which lower levels of remnant cholesterol in individuals with diabetes, are conflicting in terms of ASCVD prevention. This is likely partly due to neutral effects of these drugs on the total level of apolipoprotein B(apoB)-containing lipoproteins. Elevated remnant cholesterol remains a likely cause of ASCVD in diabetes. Remnant cholesterol-lowering therapies should also lower apoB levels to reduce risk of ASCVD.

Non-oxidative modified low-density lipoproteins: The underappreciated risk factors for atherosclerosis.

Atherosclerosis, the pathological basis of most cardiovascular diseases, is a main risk factor causing about 20 million deaths each year worldwide. Oxidized low-density lipoprotein is recognized as the most important and independent risk factor in initiating and promoting atherosclerosis. Numerous antioxidants are extensively used in clinical practice, but they have no significant effect on reducing the morbidity and mortality of cardiovascular diseases. This finding suggests that researchers should pay more attention to the important role of non-oxidative modified low-density lipoprotein in atherosclerosis with a focus on oxidized low-density lipoprotein. This review briefly summarizes several important non-oxidative modified low-density lipoproteins associated with atherosclerosis, introduces the pathways through which these non-oxidative modified low-density lipoproteins induce the development of atherosclerosis in vivo, and discusses the mechanism of atherogenesis induced by these non-oxidative modified low-density lipoproteins. New therapeutic strategies and potential drug targets are provided for the prevention and treatment of atherosclerotic cardiovascular diseases.

Female participation, and sex-specific reporting practices, in polypill randomised controlled trials in the prevention of atherosclerotic cardiovascular disease: a secondary analysis of a systematic review

Abstract Background The polypill is an emerging strategy for the prevention and management of cardiovascular disease. We assessed the participation of females in randomised controlled trials evaluating polypills for prevention of cardiovascular disease and subsequent sex-specific analyses and reporting. Methods Cardiovascular polypill trials were identified through a systematic review. Data were extracted on the use of sex-specific eligibility criteria, female participation, and the conduct, findings, and interpretation of sex-specific analyses. Results Of 26 trials included, 12 (46%) excluded groups of females, mainly if pregnant or lactating or of childbearing potential. Female participation ranged from 10% to 73% across trials. Overall, 42% of included participants were female. Of 18 trials conducted in a mostly primary prevention population, females represented 49% of trial participants. In mixed or exclusively secondary prevention trials (n=8), females represented 26% of trial participants. Females represented 46% of trial participants in trials that excluded groups of females (n=12). In trials without explicit exclusion criteria (n=13), females represented 32% of trial participants. Nine out of 26 trials reported sex-stratified analyses (35% of trials; 70% of all participants). Of these, two found some evidence for possible sex differences, both reporting larger blood pressure effects in females than males. Four trials provided sex considerations in the discussion section of the report. Conclusion The participation of females in cardiovascular polypill trials is substantially higher in primary prevention trials as compared to trials conducted in mixed or exclusively secondary prevention populations. The use of sex-specific eligibility criteria was not linked to lower female participation. Sex-specific reporting is sparsely conducted, although most frequent in larger trials.

Impact of Guideline-Directed Statin Prescriptions on Cardiovascular Outcomes by Race in a Real-World Primary Prevention Cohort

BackgroundData on real-world statin prescription in large, private health care networks and impacts on primary prevention of atherosclerotic cardiovascular disease (ASCVD) outcomes across race are scarce. ObjectivesThe purpose of this study was to investigate the impact of statin prescription on ASCVD outcomes within and across race in a large, nongovernmental health care system. MethodsStatin prescription in Black and White patients without ASCVD was evaluated (2013-2019). Guideline-directed statin intensity was defined as at least “moderate” for intermediate and high-risk patients. Statin prescription at index and ASCVD outcomes at follow-up (myocardial infarction/revascularization, stroke, mortality) were assessed via electronic health care records using International Classification of Diseases-9 and 10 codes. Cox regression models, adjusted for CVD risk factors, were used to calculate HRs for association between statin prescription and incident ASCVD events across race. ResultsAmong 270,079 patients, 7.6% (n = 20,477) and 92.4% (n = 249,602) identified as Black and White, respectively. Significantly fewer Black patients were prescribed statin therapy than White patients (13.6% vs 19.0%; P < 0.001). At a mean follow-up of 6 years, patients with “no statin” prescription vs guideline-directed statin intensity showed increased ASCVD in Black patients (HR: 1.40 [95% CI: 1.05-1.86]), and White patients (HR: 1.32 [95% CI: 1.21-1.45]; P < 0.05) and all-cause mortality. Intermediate and high-risk Black patients faced a 17% higher risk of mortality compared to White patients. However, the interaction between race and statin prescription was not a significant predictor of incident ASCVD events. ConclusionsStatins remain underprescribed. Although Black patients received proportionally less statin prescription than White patients, this was not associated with higher risk of mortality in Black patients.

Sex specific analysis of patients with and without reported statin intolerance referred to a specialized outpatient lipid clinic

BackgroundLowering LDL-cholesterol is a fundamental goal for both primary and secondary prevention of atherosclerotic cardiovascular diseases. Our study aims to analyse potential sex disparities regarding the tolerability and effectiveness of lipid-lowering therapy in patients with and without reported statin intolerance who are being treated at a lipid-outpatient clinic.MethodsFrom 2017 to 2022, n = 1062 patients (n = 612 men, n = 450 women) at high-risk were referred to our lipid-outpatient clinic because of difficulties in lipid control by primary healthcare providers. The main therapeutic objective was to optimize lipid-lowering therapy according to current treatment guidelines.ResultsPatients presented with high LDL-C baseline levels (4.97 ± 1.81 mmol/l (192 ± 70 mg/dL) in men and 5.46 ± 2.04 mmol/l (211 ± 79 mg/dL) in women). Intolerance towards statins was reported more frequently by women (48.2%) than by men (38.9%, p = 0.004). LDL-C continuously decreased with individual treatment adjustments across follow-up visits. In total, treatment goals (LDL < 1.4 mmol/l (< 55 mg/dl) or < 1.8 mmol/l (< 70 mg/dl)) were accomplished in 75.8% of men and 55.5% of women after the last follow-up visit (p < 0.0001). In men, these data are almost identical in subjects with statin intolerance. In contrast, treatment goals were reached less frequently in women with statin intolerance compared to women tolerant to statin therapy.ConclusionEven if treated in a specialized lipid clinic, women are less likely to reach their target LDL-C than men, particularly when statin intolerant. Nevertheless, many patients with statin intolerance can be successfully treated using oral combination and PCSK9 inhibitor therapy. However, ongoing follow-up care to monitor progress and to adjust treatment plans is necessary to reach this goal.

Geriatric Pharmacotherapy Case Series: Clotting and Gender-Affirming Care.

Background A transfeminine patient is a 79-year-old with past medical history significant for type 2 diabetes mellitus, hypertension, gender dysphoria, chronic kidney disease, dyslipidemia, total left hip replacement, and recent provoked deep venous thromboembolism (DVT). She was seen by a pharmacist in a primary care clinic after her discharge from a skilled nursing facility. The patient was experiencing symptoms of gender dysphoria after discontinuation of her estradiol in setting of her DVT. Assessment Her renal function was calculated to ensure she was on appropriate dosing of her medications. Because her DVT was provoked, providers determined she would require only 3 months of anticoagulation. Her laboratory test results showed a subtherapeutic estradiol level and her estradiol was restarted. Additionally, aspirin was being prescribed for primary prevention of atherosclerotic cardiovascular disease and was discontinued. Outcome She has significant improvement in her gender dysphoria symptoms with resuming her estradiol and now has a therapeutic estradiol level. She is tolerating her direct oral coagulant well and reports good quality of life. Conclusion When reviewing medications for patients it is important to take several factors into account, including dose, appropriate indication, and patient preference. Pharmacists play a key role, through collaboration with providers, in assessing these medication-specific factors. Estradiol was stopped in this patient because of her DVT, but given her DVT was provoked after a recent surgery, it was unlikely that estradiol was the cause of her clot. Weighing the risks and benefits for any patient is important when determining what medications are appropriate to continue. Additionally, calculating renal function appropriately in a gender-non-conforming patients ensures appropriate and safe dosing.
