Meta-Analysis Comparing Oral Anticoagulant Monotherapy Versus Dual Antithrombotic Therapy in Patients With Atrial Fibrillation and Stable Coronary Artery Disease.

BACKGROUND: Oral anticoagulants (OACs) are routinely used for the management of atrial fibrillation (AF) while antiplatelet agents are used in coronary artery disease (CAD). However, data regarding the comparative clinical outcomes of OAC monotherapy versus dual antithrombotic therapy (anticoagulant plus antiplatelet agent) in patients with AF and stable CAD are limited. METHODS: A comprehensive search of major databases including PubMed/MEDLINE, Cochrane Library, and Embase was performed from inception to September 1, 2024 to identify randomized control trials (RCTs) that compared OAC monotherapy with dual antithrombotic therapy in patients with AF and stable CAD. The risk ratios (RRs) were estimated with corresponding 95% confidence intervals (CIs) for all outcomes. RESULTS: A total of three RCTs reported data for 3945 patients with AF and stable CAD. The mean age of patients was 73.8 (±11.85) years and the mean follow-up was 22 months. OAC monotherapy was associated with a significantly reduced relative risk of major bleeding (RR: 0.55, 95% CI: 0.32-0.95) compared to dual therapy. The risk of all-cause death (RR: 0.85, 95% CI: 0.49-1.48), cardiovascular death (RR: 0.84, 95% CI: 0.50-1.41), any stroke event (RR: 0.74, 95% CI: 0.46-1.18), and myocardial infarction (RR: 1.57, 95% CI: 0.79-3.12) remained comparable across the two groups. CONCLUSION: OAC monotherapy led to a significant relative risk reduction for major bleeding with similar rates of ischemic events and mortality compared to dual antithrombotic therapy in patients with AF and stable CAD.

Unraveling the rapid progression of non-target lesions: risk factors and the therapeutic potential of PCSK9 inhibitors in post-PCI patients.

BACKGROUND: Rapid progression of non-target lesions (NTLs) leads to a high incidence of NTL related cardiac events post-PCI, which accounting half of the recurrent cardiac events. It is important to identify the risk factors and establish an accurate clinical prediction model for the rapid progression of NTLs post-PCI. PCSK9 inhibitors lower LDL-c levels significantly, also show the anti-inflammation effect, and may have the potential to reduce the rapid progression of NTLs post-PCI. We tried to test this hypothesis and explore the potential mechanisms. METHODS: This retrospective study included 1250 patients who underwent the first PCI and underwent repeat coronary angiography for recurrence of chest pain within 24 months. General characteristics, laboratory tests and inflammatory factors(IL-10, IL-6, IL-8, IL-1ß, sIL-2R, and TNF-α) were collected. Machine learning (LASSO regression) was mainly employed to select the important characteristic risk factors for the rapid progression of NTLs post-PCI and build prediction models. Finally, mediator analysis was employed to explore the potential mechanisms by which PCSK9 inhibitors reduce the rapid progression of NTLs post-PCI. RESULTS: There were more diabetes, less beta-blockers and PCSK9 inhibitors application, higher HbA1c, LDL-c, ApoB, TG, TC, uric acid, hs-CRP, TNF-α, IL-6, IL-8, and sIL-2R in NTL progressed group. LDL-c, hs-CRP, IL-8, and sIL-2R were characteristic risk factors for the rapid progression of NTLs post-PCI, combining LDL-c, hs-CRP, IL-8, and sIL-2R builds the optimal model for predicting the rapid progression of NTLs post-PCI (AUC = 0.632). LDL-c had a clear and incomplete mediating effect (95% CI, mediating effect: 51.56%) in the reduction of the progression of NTLs by PCSK9 inhibitors, and there was a possible mediating effect of IL-8 (90% CI), and sIL-2R (90% CI). CONCLUSIONS: LDL-c, hs-CRP, IL-8, and sIL-2R may be the key characteristic risk factors for the rapid progression of NTLs post-PCI, and combining these parameters might predict the rapid progression of NTLs post-PCI. The application of PCSK9 inhibitors had a negative correlation with the rapid progression of NTLs. In addition to the significant LDL-c-lowering, PCSK9 inhibitors may reduce the rapid progression of NTLs by reducing local inflammation of plaque.

[Relationship between clopidogrel resistance and genetic variability in Kawasaki disease children with coronary artery lesions].

Objective: To analyze the distribution of clopidogrel metabolism-related gene variability in Kawasaki disease (KD) children with coronary artery lesions (CAL) across different age groups and the impact of genetic variability on the efficacy of clopidogrel antiplatelet therapy. Methods: A retrospective cohort study was conducted. Clinical data were collected from 46 KD children with CAL who were hospitalized in the Cardiovascular Center of Children's Hospital of Fudan University between January 2021 and August 2022 and were treated with clopidogrel, including gender, age, body mass index, course of KD, CAL severity grade, and baseline platelet count. According to their age, the children were divided into ≥2-year-old group and <2-year-old group. Their platelet responsiveness was assessed by adenosine diphosphate-induced platelet inhibition rate (ADPi) calculated via thromboelastography, and children were categorized into high on-treatment platelet reactivity (HTPR) and normal on-treatment platelet reactivity (NTPR) groups. Genotypes of CYP2C19, PON1 and ABCB1 were detected. The t test, one-way analysis of variance and Chi-square test were used for intergroup comparison. Results: Among the 46 KD children with CAL, 34 were male and 12 were female; 37 were ≥2-year-old and 9 were <2-year-old; 25 cases were in the HTPR group and 21 cases were in the NTPR group, with 19 HTPR and 18 NTPR in the ≥2-year-old group, and 6 HTPR and 3 NTPR in the <2-year-old group. Genetic analysis showed that 92 alleles among the 46 children, with frequencies of CYP2C19*1, CYP2C19*2, CYP2C19*3, CYP2C19*17, PON1 192Q, PON1 192R, ABCB1 3435C, ABCB1 3435T at 59% (54/92), 32% (29/92), 9% (8/92), 1% (1/92), 36% (36/92), 64% (59/92), 63% (58/92) and 37% (34/92), respectively. Analysis of the impact of genotype on ADPi revealed that in children aged ≥2 years, those with CYP2C19*1/*3 genotype had significantly lower ADPi than those with CYP2C19*1/*1 genotype ((34±15)% vs. (61±29)%, t=2.18, P=0.036). There were also no significant difference in ADPi among children with PON1 192Q homozygous, PON1 192R heterozygote and PON1 192R homozygous genotypes ((40±22)% vs. (52±33)% vs. (65±27)%, F=2.17, P=0.130), or among those with ABCB1 3435C homozygous, ABCB1 3435T heterozygote and ABCB1 3435T homozygous genotypes ((55±34)% vs. (60±27)% vs. (49±24)%, F=0.33, P=0.719). In <2-year-old group, there were no significant differences in ADPi across CYP2C19*1/*1, CYP2C19*1/*2 and CYP2C19*2*2 genotypes ((40±20)% vs. (53±37)% vs. (34±16)%, F=0.37, P>0.05). There were no significant differences in ADPi across CYP2C19*1/*1 and CYP2C19*1/*3 genotypes ((44±27)% vs. (42±20)%, t=0.08, P>0.05). There were no significant differences in ADPi across PON1 192Q homozygous, PON1 192R heterozygote and PON1 192R homozygous genotypes (45% vs. (55±27)% vs. (24±5)%, F=1.83, P>0.05). There were no significant differences in ADPi across ABCB1 3435C homozygous, ABCB1 3435T heterozygote and ABCB1 3435T homozygous genotypes ((36±16)% vs. (50±35)% vs. 45%, F=0.29, P>0.05). The risk analysis of HTPR in different genotypes revealed that in children aged ≥2 years, carrying at least 1 or 2 loss-of-function alleles of CYP2C19 was a risk factor for HTPR (OR=4.69, 10.00, 95%CI 1.11-19.83, 0.84-119.32, P=0.033, 0.046, respectively), and PON1 192R homozygosity and carrying at least one PON1 192R allele were protective factors against HTPR (OR=0.08, 0.13, 95%CI 0.01-0.86, 0.01-1.19, P=0.019, 0.043, respectively). Conclusion: KD children aged ≥2 years carrying CYP2C19 loss-of-function alleles and PON1 192Q are more likely to develop HTPR.

Do bisphosphonates and RANKL inhibitors alter the progression of coronary artery calcification? A systematic review.

OBJECTIVES: To determine whether bisphosphonates and NF-κB ligand (RANKL) inhibitors delay coronary artery calcification (CAC). DESIGN: A systematic review was conducted. DATA SOURCES: MEDLINE, EMBASE and CENTRAL. ELIGIBILITY CRITERIA: Longitudinal studies investigating CAC progression in adults (>18 years) taking either a bisphosphonate or denosumab compared with those who did not. DATA EXTRACTION AND SYNTHESIS: Study and participant characteristics, and primary outcome ( ∆ CAC from baseline to follow-up) were extracted. The Risk Of Bias In Non-Randomised Studies-of Interventions (ROBINS-I) and Risk-of-Bias Tool for Randomised Trials (RoB2) tools were used to assess the risk of bias for observational and randomised controlled trials (RCTs), respectively. Outcome measures were reported. RESULTS: Four observational studies and one RCT (n=377) were included. Three studies solely reported the effect of bisphosphonates on ∆ CAC; one study (n=56) demonstrated a statistically significant CAC reduction in the intervention group (-372 mm3/year) compared with control (+159 mm3/year) (p<0.01). One study (n=14) demonstrated a difference in ∆ CAC between intervention (+880 mm3/year) versus control (+2220 mm3/year), however, no p value comparing groups was reported. One study (n=115) found no statistically significant difference between intervention and control.One study (n=42) exclusively investigated the effect of RANKL on ∆ CAC; there was a statistically significant reduction in CAC at 6-month follow-up between intervention (-133±124 modified Agatston unit (AU)) and control (+188±72 modified AU), p=0.03.One study (n=150) compared both bisphosphonates and denosumab to control and found no statistically significant difference between either intervention group and control over 24 months. Meta-analysis was not performed due to limited, heterogeneous studies. CONCLUSIONS: There is insufficient evidence supporting the correlation between bisphosphonate or RANKL inhibitor use and CAC progression. Further research is warranted.

Effect of Denosumab or Alendronate on Vascular Calcification: Secondary Analysis of SALTIRE2 Randomized Controlled Trial.

BACKGROUND: Patients with osteoporosis demonstrate increased vascular calcification but the effect of osteoporosis treatments on vascular calcification remains unclear. The present study aimed to examine whether coronary or aortic calcification are influenced by denosumab and alendronic acid treatment. METHODS AND RESULTS: In a double-blind randomized controlled SALTIRE2 (Study Investigating the Effect of Drugs Used to Treat Osteoporosis on the Progression of Calcific Aortic Stenosis) trial, patients with aortic stenosis were randomized 2:1:2:1 to denosumab, placebo injection, alendronic acid, or placebo capsule. Participants underwent serial imaging with computed tomography and 18F-sodium fluoride positron emission tomography for the assessment of vascular calcium burden and calcification activity, respectively. We report the prespecified secondary analyses of 24-month change in coronary calcium score, and 12-month changes in thoracic aorta calcium score, coronary and aortic 18F-sodium fluoride activity. One hundred fifty patients with aortic stenosis (72±8 years; 21% female) were randomized to denosumab (n=49), alendronic acid (n=51), and placebo (injection n=25, capsule n=25). There were no differences in change in coronary calcium scores between placebo (16 [-64 to 148] Agatston units) and either denosumab (94 [0-212] Agatston units, P=0.24) or alendronic acid (34 [-62 to 134], P=0.99). There were no differences in change in thoracic aorta calcium scores between placebo (132 [22-512] Agatston units) and either denosumab (118 [11-340], P=0.75) or alendronic acid (116 [26-498] Agatston units, P=0.62). There were no differences in changes in coronary or aortic 18F-sodium fluoride activity between treatment groups. CONCLUSIONS: Neither alendronic acid nor denosumab are associated with changes in the activity or progression of coronary or aortic calcification. Osteoporosis treatments do not appear to have major impact on vascular calcification of atherosclerosis. REGISTRATION: https://www.clinicaltrials.gov; Unique identifier: NCT02132026.

Association of semaglutide treatment with coronary artery inflammation in type 2 diabetes mellitus patients: a retrospective study based on pericoronary adipose tissue attenuation.

BACKGROUND: The pericoronary fat attenuation index (FAI) has emerged as a novel and sensitive biomarker reflecting the degree of coronary artery inflammation. Semaglutide has been demonstrated to exert a cardiovascular protective effect independent of hypoglycemia; however, its impact on coronary artery inflammation remains elusive. This study aimed to investigate the association between semaglutide treatment and coronary artery inflammation based on FAI in patients with type 2 diabetes mellitus (T2DM). METHODS: This study enrolled 497 T2DM patients who underwent coronary computed tomography angiography (CCTA) at Hebei General Hospital, of whom 93 treated with semaglutide (Sema+) and 404 did not (Sema-). Clinical data, laboratory indicators, and CCTA parameters were collected and compared between the two groups at baseline. Propensity score matching (PSM) was used to adjust for confounders, and pericoronary FAI was compared. Multivariate linear regression models were used to analyze the association between semaglutide treatment and pericoronary FAI. RESULTS: Before PSM, pericoronary FAI of the LAD and LCX was lower in patients treated with semaglutide than those without semaglutide treatment. The results of the PSM analysis revealed a lower FAI in all three major coronary arteries in the Sema + group compared to the Sema- group. Multivariate linear regression analyses revealed an independent association between semaglutide treatment and reduced FAI in all three major coronary arteries. This association varied across T2DM patients of differing profiles. CONCLUSION: Semaglutide treatment may be associated with lower coronary artery inflammation in patients with T2DM, which might partially explain its cardiovascular protective mechanism.

Association of ACEI/ARB therapy with total and cardiovascular death in coronary artery disease patients with advanced chronic kidney disease: a large multi-center longitudinal study.

INTRODUCTION: Advanced chronic kidney disease (CKD) is common among patients with coronary artery disease (CAD), and angiotensin­converting enzyme inhibitors (ACEI) or angiotensin­receptor blockers (ARB) can improve cardiac and renal function, but whether ACEI/ARB therapy improves long-term prognosis remains unclear among these high-risk patients. Therefore, this research aimed to investigate the relationship between ACEI/ARB therapy and long-term prognosis among CAD patients with advanced CKD. METHODS: CAD patients with advanced CKD were included in five hospitals. Advanced CKD was defined as estimated glomerular filtration rate (eGFR)<30 ml/min per 1.73 m2. Cox regression models and competing risk Fine and Gray models were used to examine the relationship between ACEI/ARB therapy and all-cause and cardiovascular death, respectively. RESULTS: Of 2527 patients, 47.6% population of our cohort was discharged on ACEI/ARB. The overall all-cause and cardiovascular mortality were 38.6% and 24.7%, respectively. Multivariate Cox regression analyses indicated that ACEI/ARB therapy was found to be associated with lower rates of both all-cause mortality (hazard ratio (HR)=0.836, 95% confidence interval (CI): 0.738-0.948, p = 0.005) and cardiovascular mortality (HR = 0.817, 95%CI: 0.699-0.956, p = 0.011). In the propensity-matched cohort, the survival benefit was consistent, and significantly better survival was observed for all-cause mortality (HR = 0.856, 95%CI: 0.752-0.974, p = 0.019) and cardiovascular mortality (HR = 0.830, 95%CI: 0.707-0.974, p = 0.023) among patients treated with ACEI/ARB. CONCLUSION: ACEI/ARB therapy showed a better survival benefit among high-risk CAD patients with advanced CKD at long-term follow-up, which manifested that strategies to maintain ACEI/ARB treatment may improve clinical outcomes among these high-risk populations.

What is the current knowledge on the topic? Advanced CKD is highly prevalent and strongly associated with higher mortality risk and worse outcomes among CAD patients, and patients with advanced CKD have often been excluded from randomized controlled trials, creating an evidence gap for these high-risk CAD patients. ACEI/ARB are beneficial for greater survival among CAD patients, but the effect of ACEI/ARB therapy on long-term prognosis is unclear among CAD patients with advanced CKD.What does this study add to our knowledge? ACEI/ARB treatment showed a better survival benefit among high-risk CAD patients with advanced CKD at long-term follow-up.How might this change clinical pharmacology or translational science? CAD patients with advanced CKD are not only have worse outcomes but also limited in their choice of therapy strategies. Our study may prompt an important reference for the subsequent improvement of long-term prognosis among these high-risk populations.

The journey to LDL-C goal in the era of combination lipid lowering therapy and why it matters for ASCVD patients: a UK perspective.

OBJECTIVE: We aim to explore the concept of distance and journey to goal, and consideration of these 2 elements a priori when choosing LLT. METHODS: Modelling of expected % LDL-C reductions was carried out on a range of hypothetical patients' baseline LDL-C values prior to any LLT being commenced. Therapies were then added in a stepwise manner based on the pathway demonstrated in current national guidance and compared with goal achievement on a novel LLT optimization pathway implemented in Morecambe Bay NHS Trust. RESULTS: Modelling of a stepwise lipid management pathway shows that high-intensity statin monotherapy is not sufficient in most modelled baseline LDL-C scenarios to achieve guideline-recommended goals. Furthermore, ezetimibe second line may preclude 3rd line injectable prescribing and lead to "ezetimibe limbo" where the patient is now below the reimbursement threshold for injectable prescribing but still not achieving their LDL-C target. Overall goal achievement is poor across the spectrum of modelled LDL-C levels. In contrast, by following the Morecambe Bay pathway all patients on statin for the range of hypothetical baseline LDL-C levels can reach an LDL-C target of < 1.8 mmol/L. CONCLUSIONS: This study identifies a therapeutic gap when following a stepwise approach highlighted by recent national guidance. Our proposal of a novel pathway highlights that the order in which drugs are added is important in the context of national reimbursement thresholds and allows LDL-C goal to be reached in a timely manner, regardless of the starting baseline LDL-C level.

Empagliflozin and left atrial function in patients with type 2 diabetes mellitus and coronary artery disease: insight from the EMPA-HEART CardioLink-6 randomized clinical trial.

BACKGROUND: Sodium-glucose cotransporter-2 (SGLT2) inhibitors have demonstrated reduction in heart failure outcomes in patients with type 2 diabetes mellitus, although the exact mechanism of benefit remains unclear. Alteration in left atrial (LA) function due to chronic pressure or volume overload is a hallmark of heart failure. OBJECTIVE: To evaluate the effect of the SGLT2 inhibitor empagliflozin on LA volume and function. METHODS: 90 patients with coronary artery disease and type 2 diabetes (T2DM) were randomized to empagliflozin (n = 44) or placebo (n = 46), and underwent cardiac magnetic resonance (CMR) imaging at baseline and after 6 months. The main outcome was change in LA volume; LA function, including active and passive components, was also measured by a blinded reader. RESULTS: At baseline, there was no significant difference in LA volumes between the empagliflozin (indexed maximum LA volume 26.4 ± 8.4mL/m2, minimum LA volume 11.1 ± 5.7mL/m2) and placebo (indexed maximum LA volume 28.7 ± 8.2mL/m2, minimum LA volume 12.6 ± 5.0mL/m2) groups. After 6 months, changes in LA volumes did not differ with adjusted difference (empagliflozin minus placebo): 0.99 mL/m2 (95% CI: -1.7 to 3.7 mL/m2; p = 0.47) for indexed maximum LA volume, and 0.87 mL/m2 (95% CI: -0.9 to 2.6 mL/m2; p = 0.32) for indexed minimum LA volume. Changes in total LA emptying fraction were also similar, with between-group adjusted mean difference - 0.01 (95% CI: -0.05 to 0.03, p = 0.59). CONCLUSION: SGLT2 inhibition with empagliflozin for 6 months did not have a significant impact on LA volume and function in patients with T2DM and coronary artery disease.

Impact of the Type of Anticoagulation Therapy on Long-Term Clinical Outcomes in Patients with Coronary Bifurcation Lesion and Atrial Fibrillation-Insights from the Bulgarian Bifurcation Registry.

Background and Objectives: Patients with atrial fibrillation and coronary artery disease represent a group with a greater risk of mortality. To evaluate patients with atrial fibrillation (AF) and a significant coronary bifurcation lesion and compare the clinical outcomes between the patients on anticoagulant treatment with Vitamin K antagonist (VKA) and those on direct anticoagulant (DOAC). Materials and Methods: This is a prospective study of patients with AF and stable coronary artery disease, who had evidence of a significant coronary bifurcation lesion. A log-rank test was used to assess the difference in mortality between patients taking VKA and those on DOAC. The primary endpoint was the incidence of all-cause and cardiovascular death at mid-term. Results: A total of 226 patients with AF and a significant bifurcation lesion were included. The mean age was 70.9 ± 9.2, and 70% were males. Of the patients, 123 (54.7%) were on VKA treatment, and 103 (45.3%) were taking DOAC. For a median follow-up time of 55 (39-96) months, overall mortality was 40%, whereas CV mortality was 31%. Both all-cause (28.2% versus 50.4%, p = 0.020) and CV death (12.7% versus 24.9%, p = 0.032) were significantly lower in patients taking DOAC versus those on VKA. In patients treated with PCI, CV mortality was significantly lower in patients taking DOAC (21.4% versus 40.5%, p = 0.032). VKA therapy was an independent predictor of cardiovascular death (HR 1.88; 95% CI 1.11-3.18; p = 0.01), together with chronic kidney disease (HR 1.81; 95% CI 1.13-2.92; p = 0.01). Conclusions: Treatment with DOAC in patients with atrial fibrillation and coronary bifurcation lesion was associated with significantly lower mortality independently of the treatment approach. VKA was an independent predictor of CV mortality.

PCSK9 and Coronary Artery Plaque-New Opportunity or Red Herring?

PURPOSE OF REVIEW: Although the clinical benefit of reducing low-density lipoprotein cholesterol (LDLc) in patients with coronary artery disease (CAD) is well-established, the impact on plaque composition and stability is less clear. Our narrative review aimed to assess the clinical effects of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors on coronary plaque characteristics specifically focusing from atheroma progression to regression and stabilization. RECENT FINDINGS: The combination of statin therapy and PCSK9 inhibitors (evolocumab and alirocumab) promotes plaque stability in patients following an acute coronary syndrome. The GLAGOV study highlighted the relationship between achieved LDLc levels and changes in percentage atheroma volume. Similarly, the PACMAN-AMI study concluded that the qualitative and quantitative changes in coronary plaque were associated with the levels of LDLc. Assessing the severity of coronary artery stenosis and the extent of atherosclerotic burden by means of imaging techniques (e.g., IVUS, OCT and near-infrared spectroscopic) have significantly advanced our understanding of the benefits from promoting plaque regression and achieving to features of plaque stabilization through increasingly intensive lipid-lowering strategies.

Vitamin-K antagonist versus dual antiplatelet therapy in management of isolated and non-obstructive atherosclerotic coronary artery ectasia.

BACKGROUND: Treatment of isolated and non-obstructive atherosclerotic coronary artery ectasia (CAE) is still controversial. AIM: To assess the efficacy and safety of vitamin-K antagonist (VKA) versus dual antiplatelet (DAPT) therapy in management of patients with isolated and non-obstructive atherosclerotic CAE. METHODS: We prospectively enrolled 79 patients diagnosed on elective coronary angiography to have either isolated CAE or non-obstructive atherosclerotic CAE. Patients were assigned in 1:1 pattern to receive either VKA (warfarin) or DAPT (aspirin plus clopidogrel). Patients were followed-up for nine-months. The primary endpoint was the cumulative events rate including acute coronary event, target vessel intervention, or cardiac death. Analysis of cumulative events at different time intervals, its individual components, and bleeding were considered secondary endpoints. RESULTS: Cumulative events rate was 33%, with mortality rate of 2.5%. Both treatment groups showed comparable cumulative events during the nine-months follow-up duration. Nevertheless, Kaplan-Meier analysis beyond the first 3-months of follow-up showed significantly higher event-free survival among the VKA-group. Recurrent events (≥2) were significantly higher among the DAPT-group. Both groups showed no major bleeding events. Multivariable cox-regression analysis showed that presence of significant coronary tortuosity, use of DAPT in reference to VKA, and lower percent time in therapeutic range (%TTR) among those receiving VKA were significant independent predictors of clinical adverse events beyond the first 3-months of follow-up. CONCLUSION: Cumulative adverse events were comparable among both treatment groups for isolated non-obstructive CAE. However, adverse events were significantly more frequent in the DAPT-group beyond the first three months.

Genetic Risk and Coronary Artery Calcium in Personalizing Antihypertensive Treatment: A Pooled Cohort Analysis.

OBJECTIVE: To assess the role of the systolic blood pressure polygenic risk score (SBP-PRS) in antihypertensive treatment initiation and its comparative efficacy with coronary artery calcium (CAC) scores. PATIENTS AND METHODS: This retrospective cohort study included participants with whole genome sequencing data who underwent CAC scanning between 1971 and 2008, were free of prevalent cardiovascular disease (CVD), and were not taking antihypertensive medications. The cohort was stratified by blood pressure (BP) treatment group and SBP-PRS (low/intermediate, first and second tertiles; high, third tertile) and CAC score (0 vs >0) subgroups. The primary outcome was the first occurence of adjudicated coronary heart disease, heart failure, or stroke during 10-year follow-up. The 10-year number needed to treat (NNT) to prevent 1 event of the primary outcome was estimated. A relative risk reduction of 25% for the primary outcome based on the treatment effect of intensive control (SBP <120 mm Hg) of hypertension in SPRINT (Systolic Blood Pressure Intervention Trial) was used for estimating the NNT. RESULTS: Among the 5267 study participants, the median age was 59 years (interquartile range, 51-68 years); 2817 (53.5%) were women and 2880 (54.7%) were non-White individuals. Among 1317 individuals with elevated BP/low-risk stage 1 hypertension not recommended treatment, the 10-year incidence rate of the primary outcome was 5.6% for low/intermediate SBP-PRS and 6.3% for high SBP-PRS with NNTs of 63 and 59, respectively. Similarly, the 10-year incidence rate of the primary outcome was 2.9% for CAC score 0 and 9.7% for CAC score greater than 0, with NNTs of 117 and 37, respectively. CONCLUSION: Including genetic information in risk estimation of individuals with elevated BP/low-risk stage 1 hypertension has modest value in the initiation of antihypertensive therapy. Genetic risk and CAC both have efficacy in personalizing antihypertensive therapy.

Effect of loss-of-function CYP2C19 variants on clinical outcomes in coronary artery disease patients treated with clopidogrel: A systematic meta-analysis approach.

For many years, clopidogrel has been a commonly utilised antiplatelet drug in the management of coronary artery disease (CAD). It's thought that the CYP2C19 loss of function (LoF) polymorphism causes clopidogrel's poor metabolism, which eventually leads to resistance. Previous research produced extremely divergent and inconsistent results, making it impossible to draw definitive conclusions. Therefore, current, investigation was carried out to obtain definitive evidence from an updated meta-analysis on the connection between CYP2C19 LoF polymorphism and coronary artery event in patients treated with clopidogrel. 52,542 individuals with coronary artery disease who were receiving clopidogrel treatment were included in 87 carefully chosen trials from reliable databases that we used for our meta-analysis. According to our data, those who carry one or more CYP2C19 LoF alleles worldwide are much more likely to experience composite events and coronary artery events than people who do not carry these alleles, especially in Asian populations. Our meta-analysis observed that the global population, particularly Asians receiving clopidogrel treatment, is at risk of recurrent coronary artery events and composite events if they carry the CYP2C19 LoF alleles. Additional research is essential on alternative antiplatelet therapies for individuals who exhibit poor or intermediate metabolic activity. OBJECTIVES: 1.To systematically analyze the current evidence regarding the association of CYP2C19 variants with coronary artery disease (CAD). 2.To conduct a meta-analysis to investigate the association between loss of function (LoF) CYP2C19 modifications and CAD.

Effect of rosuvastatin versus atorvastatin on new-onset diabetes mellitus in patients treated with high-intensity statin therapy for coronary artery disease: a post-hoc analysis from the LODESTAR randomized clinical trial.

BACKGROUND: The impact of rosuvastatin versus atorvastatin on new-onset diabetes mellitus (NODM) among patients treated with high-intensity statin therapy for coronary artery disease (CAD) remains to be clarified. This study aimed to evaluate the risk of NODM in patients with CAD treated with rosuvastatin compared to atorvastatin in the randomized LODESTAR trial. METHODS: In the LODESTAR trial, patients with CAD were randomly assigned to receive either rosuvastatin or atorvastatin using a 2-by-2 factorial randomization. In this post-hoc analysis, the 3-year incidence of NODM was compared between rosuvastatin and atorvastatin treatment in the as-treated population with high-intensity statin therapy as the principal population of interest. RESULTS: Among 2932 patients without diabetes mellitus at baseline, 2377 were included in the as-treated population analysis. In the as-treated population with high-intensity statin therapy, the incidence of NODM was not significantly different between the rosuvastatin and atorvastatin groups (11.4% [106/948] versus 8.8% [73/856], hazard ratio [HR] = 1.32, 95% confidence interval [CI] = 0.98 to 1.77, P = 0.071). When the risk of NODM with rosuvastatin versus atorvastatin was assessed according to the achieved low-density lipoprotein cholesterol (LDL-C) level, the risk of NODM began to increase at a LDL-C level below 70 mg/dL. The incidence of NODM was significantly greater in the rosuvastatin group than it was in the atorvastatin group when the achieved LDL-C level was < 70 mg/dL (13.9% versus 8.0%; HR = 1.79, 95% CI 1.18 to 2.73, P = 0.007). CONCLUSIONS: Among CAD patients receiving high-intensity statin therapy, the incidence of NODM was not significantly different between rosuvastatin and atorvastatin. However, a drug effect of the statin type on NODM was observed when the achieved LDL-C level was < 70 mg/dL. TRIAL REGISTRATION: ClinicalTrials.gov, Identifier: NCT02579499.

Clinical Performance and Persistence on Dual Pathway Inhibition with Rivaroxaban and Aspirin in Real-World Setting.

ABSTRACT: The dual pathway inhibition (DPI) with low-dose rivaroxaban and aspirin in patients with stable atherosclerotic vascular disease reduces the occurrence of cardiovascular events, with no significant increase of intracranial or other critical organ bleedings. Our observational study aimed to describe the clinical performance, adherence, and persistence of DPI therapy among a real-world setting of patients with an established diagnosis of coronary artery (CAD) and/or peripheral artery disease (PAD). We prospectively included all consecutive patients with an established diagnosis of CAD and/or PAD treated with aspirin (ASA) 100 mg once daily and rivaroxaban 2.5 mg twice daily. Clinical evaluation was performed at baseline, before starting treatment, at 1 month, and every 6 months after the study drug administration. A total of 202 consecutive patients (mean age 66 ± 10 years; male 80%) eligible to DPI therapy were included. During a mean follow-up of 664 ± 177 days, the incidence rate of major bleedings and of major adverse cardiovascular events was 0.8 and 1.1 per 100 patients/year, respectively. The adherence to pharmacological treatment was 99%. Additionally, 13.4% of patients suspended the DPI therapy during the follow-up. Minor bleedings resulted the most common cause of both temporary and permanent DPI therapy discontinuation. This observational study supports the safety of DPI with low-dose rivaroxaban and aspirin among patients with CAD and PAD in a real-world setting, showing high persistence and maximum adherence to medical treatment.

The changes of coagulation profiles in Kawasaki disease and its associations with clinical classification, intravenous immunoglobulin responsiveness and coronary artery involvement.

Coagulation disorders are common in Kawasaki disease (KD). The main objectives of the present study were to probe the associations of coagulation profiles with clinical classification, IVIG responsiveness, coronary artery abnormalities (CAAs) in the acute episode of KD. A total of 313 KD children were recruited and divided into six subgroups, including complete KD (n = 217), incomplete KD (n = 96), IVIG-responsive KD (n = 293), IVIG-nonresponsive KD (n = 20), coronary artery noninvolvement KD (n = 284) and coronary artery involvement KD (n = 29). Blood samples were collected within 24-h pre-IVIG therapy and 48-h post-IVIG therapy. Coagulation profiles, conventional inflammatory mediators and blood cell counts were detected. Echocardiography was performed during the period from 2- to 14-day post-IVIG infusion. In addition, 315 sex- and age-matched healthy children were enrolled as the controls. (1) Before IVIG therapy, coagulation disorders were more prone to appear in KD patients than in healthy controls, and could be overcome by IVIG therapy. FIB and DD significantly increased in the acute phase of KD, whereas reduced to normal levels after IVIG therapy. (2) PT and APTT were significantly longer in patients with complete KD when compared with their incomplete counterparts after IVIG therapy. (3) The larger δDD, δFDP and the smaller δPT, δINR predicted IVIG nonresponsiveness. (4) The higher δDD and δFDP correlated with a higher risk for CAAs (DD: r = -0.72, FDP: r = -0.54). Coagulation disorders are correlated with complete phenotype, IVIG nonresponsiveness and CAA occurrence in the acute episode of KD, and can be rectified by synergistic effects of IVIG and aspirin.

Trends in prognosis and use of SGLT2i and GLP-1 RA in patients with diabetes and coronary artery disease.

OBJECTIVE: To explore trends in prognosis and use of glucose-lowering drugs (GLD) in patients with diabetes and coronary artery disease (CAD). RESEARCH DESIGN AND METHODS: All patients with diabetes and CAD undergoing a coronary angiography between 2010 and 2021 according to the Swedish Angiography and Angioplasty Registry were included. Information on GLD (dispended 6 months before or after coronary angiography) was collected from the Swedish Prescribed Drug Registry. Data on major cardiovascular events (MACE; mortality, myocardial infarction, stroke, heart failure) through December 2021 were obtained from national registries. Cox proportional survival analysis was used to assess outcomes where cardioprotective GLD (any of Sodium Glucose Lowering Transport 2 receptor inhibitors [SGLT2i] and Glucagon Like Peptide Receptor Agonists [GLP-1 RA]) served as a reference. RESULTS: Among all patients (n = 38,671), 31% had stable CAD, and 69% suffered an acute myocardial infarction. Mean age was 69 years, 67% were male, and 81% were on GLD. The use of cardioprotective GLD increased rapidly in recent years (2016-2021; 7-47%) and was more common in younger patients (66 vs. 68 years) and men (72.9% vs. 67.1%) than other GLD. Furthermore, compared with other GLD, the use of cardioprotective GLD was more common in patients with a less frequent history of heart failure (5.0% vs. 6.8%), myocardial infarction (7.7% vs. 10.5%) and chronic kidney disease (3.7% vs. 5.2%). The adjusted hazard ratio (HR) (95% CI) for MACE was greater in patients on other GLD than in those on cardioprotective GLD (1.10; 1.03-1.17, p = 0.004). Trend analyses for the years 2010-2019 revealed improved one-year MACE in patients with diabetes and CAD (year 2019 vs. 2010; 0.90; 0.81-1.00, p = 0.045), while 1-year mortality was unchanged. CONCLUSIONS: The prescription pattern of diabetes medication is changing quickly in patients with diabetes and CAD; however, there are worrying signals of inefficient use prioritizing cardioprotective GLD to younger and healthier individuals at lower cardiovascular risk. Despite this, there are improving trends in 1-year morbidity.
