Possibilities of combined hypolipidemic therapy in different categories of high and very high cardiovascular risk patients (a pilot study)

Aim of the study was to evaluate the efficacy and safety of the combined use of statins with ezetimibe in patients of various nosological groups of high and very high cardiovascular risk. Material and methods. A prospective interventional non-randomized study included 40 people, mean age 60.7±9.5 years, high and very high cardiovascular risk, who did not receive statin therapy or took statins without reaching the target low density lipoprotein (LDL) cholesterol values. Patients were recommended to receive high-intensity statin therapy in combination with ezetimibe for 3 months. Biochemical parameters were determined by standard enzymatic methods and the beginning of combined lipid-correcting therapy and after 3 months. Results. In patients with high cardiovascular risk, the level of total cholesterol decreased by 39.7 % 3 months after treatment (6.8 ± 2.5 and 4.7 ± 2.5 mmol/L; p = 0.0001), the level of LDL cholesterol by 52.2 % (4.6 ± 2.4 and 2.8 ± 2.2 mmol/L; p = 0.0001), the TG level by 26 % (2.7 ± 1.1 and 2.0 ± 1.0 mmol/L; p = 0.008). In the group of patients with very high cardiovascular risk, we also noted a decrease in the total cholesterol level by 39.1 % (6.4 ± 1.4 and 4.4 ± 1.2 mmol/L; p = 0.0001), the level of LDL cholesterol by 45.5 % (4.4 ± 1.4 and 2.5 ± 0.9 mmol/L; p = 0.0001). We did not find statistically significant changes in the remaining lipid parameters. LDL cholesterol targets were achieved in 64 % of patients with high and 52 % of very high cardiovascular risk. There were no significant changes in activity of alanine and aspartate amino transferases, content creatine phosphokinase, glucose and glycated hemoglobin, glomerular filtration rate. Conclusions. Initial combination therapy with statin and ezetimibe is well tolerated and can reduce LDL cholesterol levels by 2 times within 3 months in various categories of patients with high and very high cardiovascular risk.

Effectiveness of lipid-lowering therapy in outpatients with coronary artery disease living in a large industrial center of Eastern Siberia

Aim. To study the prescription rate of lipid-lowering therapy and achieving the target low-density lipoprotein cholesterol (LDL-C) values in outpatients with coronary artery disease (CAD) living in Krasnoyarsk.Material and methods. The study included all patients with CAD hospitalized in the cardiology department of the clinic of the Research Institute of Medical Problems of the North (Krasnoyarsk) in 2018-2019. The analysis included data from 1671 patients (men, 770; women, 901). During hospitalization, an in-depth survey of patients was carried out on the subject of prescribing and taking lipid-lowering drugs. On admission, lipid profile was assessed in all patients.Results. At the time of admission, only 51,4% of patients received lipidlowering therapy. The majority received statin monotherapy (99,2%). Only 0,8% of patients received combination therapy (statin+ezetimibe). The most frequently prescribed statin in the study was atorvastatin — 74,6%. Rosuvastatin was received by 17,1% of patients. In most cases, the doses of atorvastatin and rosuvastatin corresponded to the moderate-intensity statin therapy regimen. The frequently prescribed dose of atorvastatin was 20 mg/day — 54,4%, rosuvastatin — 10 mg/day — 68,7%. The target level of LDL-C <1,8 mmol/L was reached by 16,3%, <1,5 mmol/L — by 9,0%, <1,4 mmol/L — only 6,5% of patients. Most often, the target LDL-C levels were achieved by patients receiving high-intensity statin (HIS) therapy. The target level of LDL-C <1,8 mmol/L was reached by 37,5%, <1,5 mmol/L — 23,9%, LDL cholesterol <1,4 mmol/L — 20,7% of patients, receiving HIS.Conclusion. In patients with CAD living in Krasnoyarsk, the most commonly prescribed statins were atorvastatin and rosuvastatin, but only 32% of patients received HIS. Combination lipid-lowering therapy has been used extremely rarely. Among the surveyed patients, the current target level of LDL-C for patients with CAD (<1,4 mmol/L) was achieved only in 6,5% of patients. In the group of patients receiving high-intensity statin therapy, this target level was achieved in 20,7% of patients, which indicates the need for strict adherence to current clinical guidelines.

Pharmacist-Led Programs to Increase Statin Prescribing: A Narrative Review of the Literature

Statins are lipid-lowing medications shown to reduce cardiovascular events and are recommended for specific patient populations at elevated risk of atherosclerotic cardiovascular disease (ASCVD). Despite the demonstrated efficacy of statins for reducing ASCVD risk, and guidance on which populations should receive statin therapy, a substantial portion of eligible patients are not prescribed statin therapy. Pharmacists have attempted to increase the number of eligible patients receiving appropriate statin therapy through a variety of interventions and across several clinical settings. In this article, we highlight multiple studies evaluating the effectiveness of pharmacist-led interventions to improve statin use. A total of seven studies were selected for this narrative review, demonstrating the effectiveness and barriers of different statin-initiation programs delivered by pharmacists to increase statin use in eligible patients. Among the interventions assessed, a combination of provider communicating and statin prescribing through collaborative drug therapy management (CDTM) appear to the be the most useful at increasing statin use. Pharmacists can significantly improve statin use rates among eligible patients through multiple intervention types and across different clinical settings. Further studies should evaluate continued statin adherence and clinical outcomes among patients served by pharmacists.

Personalizing cholesterol treatment recommendations for primary cardiovascular disease prevention

Statin therapy is the cornerstone of preventing atherosclerotic cardiovascular disease (ASCVD), primarily by reducing low density lipoprotein cholesterol (LDL-C) levels. Optimal statin therapy decisions rely on shared decision making and may be uncertain for a given patient. In areas of clinical uncertainty, personalized approaches based on real-world data may help inform treatment decisions. We sought to develop a personalized statin recommendation approach for primary ASCVD prevention based on historical real-world outcomes in similar patients. Our retrospective cohort included adults from a large Northern California electronic health record (EHR) aged 40–79 years with no prior cardiovascular disease or statin use. The cohort was split into training and test sets. Weighted-K-nearest-neighbor (wKNN) regression models were used to identify historical EHR patients similar to a candidate patient. We modeled four statin decisions for each patient: none, low-intensity, moderate-intensity, and high-intensity. For each candidate patient, the algorithm recommended the statin decision that was associated with the greatest percentage reduction in LDL-C after 1 year in similar patients. The overall cohort consisted of 50,576 patients (age 54.6 ± 9.8 years) with 55% female, 48% non-Hispanic White, 32% Asian, and 7.4% Hispanic patients. Among 8383 test-set patients, 52%, 44%, and 4% were recommended high-, moderate-, and low-intensity statins, respectively, for a maximum predicted average 1-yr LDL-C reduction of 16.9%, 20.4%, and 14.9%, in each group, respectively. Overall, using aggregate EHR data, a personalized statin recommendation approach identified the statin intensity associated with the greatest LDL-C reduction in historical patients similar to a candidate patient. Recommendations included low- or moderate-intensity statins for maximum LDL-C lowering in nearly half the test set, which is discordant with their expected guideline-based efficacy. A data-driven personalized statin recommendation approach may inform shared decision making in areas of uncertainty, and highlight unexpected efficacy-effectiveness gaps.

The Pharmacogenetics of Statin Therapy on Clinical Events: No Evidence that Genetic Variation Affects Statin Response on Myocardial Infarction

Background: The pharmacogenetic effect on cardiovascular disease reduction in response to statin treatment has only been assessed in small studies. In a pharmacogenetic genome wide association study (GWAS) analysis within the Genomic Investigation of Statin Therapy (GIST) consortium, we investigated whether genetic variation was associated with the response of statins on cardiovascular disease risk reduction.Methods: The investigated endpoint was incident myocardial infarction (MI) defined as coronary heart disease death and definite and suspect non-fatal MI. For imputed single nucleotide polymorphisms (SNPs), regression analysis was performed on expected allelic dosage and meta-analysed with a fixed-effects model, inverse variance weighted meta-analysis. All SNPs with p-values &lt;5.0 × 10−4 in stage 1 GWAS meta-analysis were selected for further investigation in stage-2. As a secondary analysis, we extracted SNPs from the Stage-1 GWAS meta-analysis results based on predefined hypotheses to possibly modifying the effect of statin therapy on MI.Results: In stage-1 meta-analysis (eight studies, n = 10,769, 4,212 cases), we observed no genome-wide significant results (p &lt; 5.0 × 10−8). A total of 144 genetic variants were followed-up in the second stage (three studies, n = 1,525, 180 cases). In the combined meta-analysis, no genome-wide significant hits were identified. Moreover, none of the look-ups of SNPs known to be associated with either CHD or with statin response to cholesterol levels reached Bonferroni level of significance within our stage-1 meta-analysis.Conclusion: This GWAS analysis did not provide evidence that genetic variation affects statin response on cardiovascular risk reduction. It does not appear likely that genetic testing for predicting effects of statins on clinical events will become a useful tool in clinical practice.

Statin Therapy May Be Associated with Reduced Mortality Risk of Sepsis Patients: A Retrospective Study from the MIMIC-IV Database

BackgroundIt is controversial whether statin therapy is beneficial for sepsis patients. A large retrospective cohort study was conducted to evaluate the association between statin therapy and mortality in sepsis patients.MethodsAdult (≥18 years) sepsis patients were enrolled and divided into two groups: the statin group and the no-statin group. Data including demographic features, vital signs, laboratory tests, and comorbidities from MIMIC-IV v1.0 were extracted. Delirium was assessed via the Confusion Assessment Method for the ICU (CAM-ICU). Ninety-day mortality, 28-day mortality and the incidence of delirium after statin therapy were evaluated using multivariable logistic analysis, the PSM model and subgroup analysis based on univariate analysis. ResultsIn univariate analysis and multivariable logistic analysis, statin therapy showed a significant association with both reduced 28-day and 90-day mortality (90-day mortality: OR 0.58, 95% CI: 0.46-0.72, p<0.001; 28-day mortality: OR 0.47, 95% CI: 0.37-0.60, p<0.001), while no relationship was found between statin therapy and delirium (OR 0.92, 95% CI: 0.49-1.72, p=0.787). In further PSM model and subgroup analyses or sensitivity analysis, consistent results were shown. ConclusionStatin therapy is significantly associated with 28-day and 90-day mortality without decrease in the incidence of delirium.

Effects of statin therapy on coronary plaque volume by decreasing CRP/hsCRP levels: A meta-regression of randomized controlled trials

Background and aims: Several clinical trials have indicated that statins stabilize and reverse atherosclerotic plaque. However, different studies have provided inconsistent findings regarding mechanisms and influencing factors of plaque regression under statin therapy. In this study, meta-analysis and meta-regression were used to determine the effect of statin medication on coronary plaque volume as determined by intravenous ultrasound. Meanwhile, the impact of statins on CRP/hsCRP reduction on plaque regression was discussed. Methods: Up to May 28, 2021, a systematic PubMed, EMBASE, and Cochrane search was performed for randomized controlled trials that assessed treatment effect using total atheroma volume (TAV), percent atheroma volume (PAV), or plaque volume (PV). Only CRP/hsCRP and LDL-C values reported before and after treatment were considered. Results: 12 studies fulfilled the inclusion criteria and were included in the systematic review. Compared with control groups, meta-analysis of 15 statin-treated arms reported change of TAV/PV showed standardized mean difference (SMD) at -0.27 (95% confidence intervals [CI]: -0.42, -0.12). Meta-analysis of 7 studies reported change of PAV revealed SMD at -0.16 (95% CI: -0.29, -0.03). Meta-regression analysis revealed percent change of CRP/hsCRP statistically influences SMD in change of TAV/PVafter adjusting for percent change of LDL-C, age and gender. Meta-regression analysis showed that percent change of CRP/hsCRP statistically influences SMD in change of PAV. Conclusion: In conclusion, statin therapy is beneficial for plaque regression. Statins promote plaque regression through their anti-inflammatory ability while lowering LDL-C is unaffected.
