Integration of Primary Preventive Care of Cardiovascular Disease in a Retroviral Clinic in an adult retroviral clinic in Ibadan: A retrospective study.

A consequence of improved survival of people living with human immunodeficiency virus (HIV) (PLHIV) is an aging population with an increased risk of developing atherosclerotic cardiovascular diseases (ASCVDs). International guidelines recommend primary preventive strategies which should be integrated into routine care of PLHIV. This study audited the ASCVD preventive practices offered to PLHIV at the adult antiretroviral clinic in Ibadan. This was a retrospective review of clinical records of all persons who were recruited into the antiretroviral therapy clinic between January 1 and December 31, 2018. Cardiovascular disease (CVD) preventive practices were audited against recommendations of the American Heart Association for PLHIV. The records of 568 persons with a mean (standard deviation) age of 39.95 (11.77) years were reviewed. There were 365 (64.26%) females and 203 (35.74%) males. Only 364 (64.08%) patients had the required parameters for the calculation of the low-density lipoprotein cholesterol (LDL-C) by the Friedewald formula. Ten-year ASCVD risk was not calculated for any of the patients during their clinic visits. Thirty-seven (6.51%) patients had either an LDL-C ≥4.91 mmol/L or an age between 40 and 75 years with diabetes mellitus or ASCVD risk score (when calculated) ≥ 7.5%. Only one of these persons was referred for specialist care of lifestyle modification. Fifty (8.80%) persons had an eGFR <60 mLs/min, but only 11 (1.94%) were referred for nephrology care. The integration of primary preventive cardiovascular practices into routine care for PLHIV is suboptimal. A revision of the recommendations of the Nigerian National Guidelines for HIV may be a useful first step addressing this.

Digital Innovation to Grow Quality Care Through an Interprofessional Care Team (DIG IT) Among Underserved Patients With Hypertension.

The impact of digital health on medically underserved patients is unclear. This study aimed to determine the early impact of a digital innovation to grow quality care through an interprofessional care team (DIG IT) on the blood pressure (BP) and 10-year atherosclerotic cardiovascular disease (ASCVD) risk score of medically underserved patients. This was a 3-month, prospective intervention study that included patients aged 40 years or more with BP of 140/90 mmHg or higher who received care from DIG IT from August through December 2021. Sociodemographic and clinical outcomes of DIG IT were compared with historical controls (controls) whose data were randomly extracted by the University of California Data Warehouse and matched 1:1 based on age, ethnicity, and baseline BP of the DIG IT arm. Multiple linear regression was performed to adjust for potential confounding factors. A total of 140 patients (70 DIG IT, 70 controls) were included. Both arms were similar with an average age (SD) of 62.8 (9.7) years. The population was dominated by Latinx (79.3%) persons, with baseline mean BP of 163/81 mmHg, and mean ASCVD risk score of 23.9%. The mean (SD) reduction in systolic BP at 3 months in the DIG IT arm was twice that of the controls (30.8 [17.3] mmHg vs 15.2 [21.2] mmHg; P <.001). The mean (SD) ASCVD risk score reduction in the DIG IT arm was also twice that of the controls (6.4% [7.4%] vs 3.1% [5.1%]; P = .003). The DIG IT was more effective than controls (receiving usual care). Twofold improvement in the BP readings and ASCVD scores in medically underserved patients were achieved with DIG IT.

Impact of Nonalcoholic Hepatic Steatosis on the Warranty Period of a Coronary Artery Calcium Score of 0: Results From the Multi-Ethnic Study of Atherosclerosis.

For individuals with a coronary artery calcium (CAC) score of 0, CAC rescans at appropriate timings are recommended, depending on individual risk profiles. Although nonalcoholic fatty liver disease, recently redefined as metabolic-associated fatty liver disease, is a risk factor for atherosclerotic cardiovascular disease events, its relationship with the warranty period of a CAC score of 0 has not been elucidated. A total of 1944 subjects from the MESA (Multi-Ethnic Study of Atherosclerosis) with a baseline CAC score of 0, presence or absence of nonalcoholic hepatic steatosis, and at least 1 follow-up computed tomography scan were included. Nonalcoholic hepatic steatosis was defined using nonenhanced computed tomography and liver/spleen attenuation ratio <1. The association between nonalcoholic hepatic steatosis and new CAC incidence (CAC score >0) was evaluated using a Weibull survival model. Nonalcoholic hepatic steatosis was identified in 268 (14%) participants. Participants with nonalcoholic hepatic steatosis had higher CAC incidence than those without nonalcoholic hepatic steatosis. Nonalcoholic hepatic steatosis was independently associated with new CAC incidence after adjustment for atherosclerotic cardiovascular disease risk factors (hazard ratio, 1.28 [95% CI, 1.05-1.57]; P=0.015). Using a 25% testing yield (25% of participants with zero CAC at baseline would be expected to have developed a CAC score >0), the warranty period of a CAC score of 0 in participants with nonalcoholic hepatic steatosis was shorter than in those without nonalcoholic hepatic steatosis (4.7 and 6.3 years). This association was consistent regardless of sex, race/ethnicity, age, and 10-year atherosclerotic cardiovascular disease risk. Nonalcoholic hepatic steatosis had an impact on the warranty period of a CAC score of 0. The study suggests that the time period until a CAC rescan should be shorter in those with nonalcoholic hepatic steatosis and a CAC score of 0.

Impact of metabolic bariatric surgery on outcomes and the 10-year risk of major adverse cardiovascular events during a 7-year period: a retrospective cohort study.

Metabolic bariatric surgery offers enduring weight reduction and alleviation of obesity-related comorbidities, including dyslipidemia, diabetes, hypertension, and major adverse cardiovascular events (MACE). Long-term data on one-anastomosis gastric bypass (OAGB) and single-anastomosis duodenal-jejunal bypass with sleeve gastrectomy (SADJB-SG) is lacking, necessitating this investigation. In this multicenter prospectively-collected retrospective observational study, 830 adult Taiwanese patients (682 OAGB, 148 SADJB-SG) who underwent surgery from 1 January 2011 to 31 December 2017, were initially identified. Following protocol, 224 patients (177 OAGB, 47 SADJB-SG) with complete follow-up data at various intervals up to 3 years after surgery were included in the final analysis. The study's primary focus is to evaluate the long-term safety, efficacy, and durability of OAGB and SADJB-SG in promoting weight loss and diabetes remission. Additionally, changes in 10-year and lifetime risks of MACE before and 3-year after surgery are assessed using Taiwan MACE risk prediction model and the China-PAR project model. SADJB-SG patients exhibit higher diabetes prevalence, lower BMI, and more severe diabetes compared to OAGB. Both groups demonstrate significant improvements in BMI, diabetes, hypertension, and dyslipidemia three years after surgery, with the most substantial improvements occurring in the second year. The Taiwan MACE risk model reveals a significant reduction in 10-year MACE and stroke risks for both groups. The China-PAR project model indicates a synchronized reduction in atherosclerotic cardiovascular disease 10-year and lifetime risk in both OAGB and SADJB-SG groups. OAGB and SADJB-SG exhibit sustained improvements in weight reduction and obesity-related comorbidities over 3 years after surgery. Notably, both procedures contribute to a substantial reduction in 10-year MACE, stroke, and atherosclerotic cardiovascular disease risks. These findings underscore the efficacy of OAGB and SADJB-SG in the context of metabolic bariatric surgery.

Incidence of cardiovascular events in a population-based Danish cohort with atopic dermatitis

The risk of cardiovascular disease in atopic dermatitis (AD) is not well established. Our aims were to evaluate the incidence rate (IR) of venous thromboembolism (VTE) in patients with AD in a population-based cohort study and to assess atherosclerotic cardiovascular disease (ASCVD) risk factors and incidence of malignancies, major adverse cardiovascular events (MACE), and VTE in patients with AD and rheumatoid arthritis (RA) in a nested cohort analysis. Data from individuals age 12 years or older (nested cohort age≥ 18 years) from January 1, 2000, to December 31, 2018, were extracted from the Danish National Patient Registry. Patients with AD were age- and sex-matched with 10 healthy controls. ASCVD risk factors included age 65 years or older and history of smoking, coronary artery disease, stroke, deep vein thrombosis (DVT), pulmonary embolism (PE), and malignancy. The population-based cohort comprised 190,751 patients (17,341 patients with AD and 173,410 healthy controls). The IRs per 100 patient-years were comparable between the AD cohort and healthy controls for VTE (0.14 [95% CI= 0.12-0.16] vs 0.11 [95% CI= 0.11-0.12]), DVT (0.08 [95% CI= 0.06-0.09] vs 0.06 [95% CI= 0.06-0.07]), and PE (0.06 [95% CI= 0.05-0.08] vs 0.05 [95% CI= 0.05-0.05]). The IR for VTE was higher in the AD cohort age 65 years or older (0.71 [95% CI= 0.56-0.90]) than in the age-matched controls (0.50 [95% CI= 0.46-0.54]). ASCVD risk factors were more frequent in the patients with RA than in the patients with AD. The IRs for malignancies and MACE were higher with specific ASCVD risk factors. The IRs of cardiovascular events were comparable between the AD cohort and general population. The risk of VTE, malignancy, or MACE was higher with specific ASCVD risk factors, underscoring the need for patient monitoring.

Efficacy of Traditional Anti-lipidemic Drugs in Lowering Lipoprotein(a) Levels: A Systematic Review.

Lipoprotein(a), or Lp(a), was identified in the early 1960.Its role as an independent risk factor for atherosclerotic cardiovascular disease (ASCVD) became widely recognized by the late 20th century, regardless of other traditional risk markers such as low-density lipoproteins and high-density lipoproteins. This study aimed to systematically review available literature and compare the efficacy of different lipid-lowering drugs, both approved for clinical use and currently undergoing trials, in lowering Lp(a) levels. A comprehensive search of medical databases including PubMed, PubMed Central (PMC), Medline, ScienceDirect, Cochrane Library, and Google Scholar was conducted to identify relevant studies. A total of 29 research papers met the inclusion criteria, focusing on the impact of various lipid-lowering drugs on Lp(a) concentration in patients with significantly elevated baseline Lp(a) levels. Plasma Lp(a) levels exceeding 30 mg/dL are associated with a higher risk of ASCVD, including myocardial infarction, stroke, aortic valve stenosis, heart failure, peripheral arterial disease, and increased all-cause mortality. Most commonly used lipid-lowering agents, such as statins, fibrates, ezetimibe, and nutraceuticals like coenzyme Q10 (CoQ10), showed no significant effect on Lp(a) plasma levels. However, Lp(a) apheresis and proprotein convertase subtilisin/kexin type 9 (PCSK-9) inhibitors were found to effectively reduce plasma Lp(a) concentrations. Emerging therapies targeting apolipoprotein(a) RNA, including anti-sense oligonucleotides (ASO) and small interfering RNA (siRNA), significantly reduced Lp(a) levels in Phase 2 trials. While several lipid-lowering agents have minimal impact on Lp(a) levels, therapies like Lp(a) apheresis, PCSK-9 inhibitors, and novel RNA-targeting drugs show promise in effectively reducing Lp(a) concentrations. However, whether these reductions translate into decreased cardiovascular events remains to be determined.

Recent Advances in Targeted Management of Inflammation In Atherosclerosis: A Narrative Review.

Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality despite effective low-density lipoprotein cholesterol-targeted therapies. This review explores the crucial role of inflammation in the residual risk of ASCVD, emphasizing its impact on atherosclerosis progression and plaque stability. Evidence suggests that high-sensitivity C-reactive protein (hsCRP), and potentially other inflammatory biomarkers, can be used to identify the inflammatory residual ASCVD risk phenotype and may serve as future targets for the development of more efficacious therapeutic approaches. We review the biological basis for the association of inflammation with ASCVD, propose new therapeutic strategies for the use of inflammation-targeted treatments, and discuss current challenges in the implementation of this new treatment paradigm for ASCVD.

Characteristics, Physiopathology and Management of Dyslipidemias in Pregnancy: A Narrative Review.

Dyslipidemia is a significant risk factor for atherosclerotic cardiovascular disease (ASCVD). During pregnancy, physiological changes elevate cholesterol and triglyceride levels to support fetal development, which can exacerbate pre-existing conditions and lead to complications such as pre-eclampsia, gestational diabetes, and increased ASCVD risk for both mother and child. Effective management strategies are necessary, especially for pregnant women with inherited forms of dyslipidemia (i.e., familial hypertriglyceridemia, hyperchylomicronemia), where personalized dietary adjustments are crucial for successful pregnancy outcomes. Pharmacological interventions and lipoprotein apheresis may be necessary for severe cases, though their use is often limited by factors such as cost, availability, and potential fetal risks. Despite the promise of advanced therapies, their widespread application remains constrained by limited studies and high costs. Thus, a personalized, multidisciplinary approach is essential for optimizing outcomes. This review provides a comprehensive overview of current strategies and evidence-based practices for managing dyslipidemia during pregnancy, emphasizing the balance of maternal and fetal health. Additionally, it discusses the physiological changes in lipid metabolism during pregnancy and their implications, particularly for women with inherited forms of dyslipidemia.

Coronary Artery Calcium for Risk Stratification Among Persons With Very High HDL Cholesterol

BackgroundCompared to normal high-density lipoprotein (HDL) cholesterol values, very high HDL cholesterol is associated with a higher incidence of mortality and atherosclerotic cardiovascular disease (ASCVD). As such, clinical risk stratification among persons with very high HDL cholesterol is challenging. ObjectivesAmong persons with very high HDL cholesterol, the purpose was to determine the prevalence of coronary artery calcium (CAC) and compare the association between traditional risk factors vs CAC for all-cause mortality and ASCVD. MethodsThe primary analysis was completed among 446 participants from the Cedars-Sinai Medical Center of the CAC Consortium with very high HDL cholesterol (≥77 mg/dL in men, ≥97 mg/dL in women). Cox proportional hazards regression assessed the association of CAC and traditional risk factors with all-cause mortality during a median follow-up of 10.7 years. Replication and validation analyses were performed for all-cause mortality among 119 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) with very high HDL cholesterol, who also had information on incident ASCVD. ResultsThe mean age was 57.9 years old, 49% were women, and the median HDL cholesterol was 98 mg/dL. One-half of participants (50%) had prevalent CAC, in whom the median CAC score was 118. Prevalent CAC conferred a 3.6-fold higher risk of all-cause mortality (HR: 3.64; 95% CI: 1.21-11.01), which appeared to be a more robust predictor than individual traditional risk factors beyond age. In the validation sample, prevalent CAC but not individual traditional risk factors were associated with all-cause mortality (HR: 2.39; 95% CI: 1.07-5.34) and a 4.0-fold higher risk of ASCVD (HR: 4.06; 95% CI: 1.11-14.84). ConclusionsMeasurement of CAC may facilitate clinical risk assessment among individuals with very high HDL cholesterol.

Cardiovascular risk in US adults with nonalcoholic steatohepatitis (NASH) vs. matched non-NASH controls, National Health and Nutrition Examination Survey, 2017-2020.

NASH is considered a contributor to atherosclerotic cardiovascular disease (ASCVD) risk; however, its contribution beyond traditional risk factors for CVD, particularly diabetes, is less clearly understood. This study aimed to quantify the cardiovascular-event risk associated with NASH, independent of diabetes status. A cross-sectional analysis was conducted using the 2017-2020 NHANES pre-pandemic cycle. NASH was defined based on presence of steatosis without other causes of liver disease, and FibroScan+AST score from vibration-controlled transient elastography (VCTE). Significant fibrosis (stages F2-F4) was identified by liver stiffness measurement from VCTE. Predicted primary CV-event risk was estimated using both the Pooled Cohort Equations (PCE) and the Framingham Risk Score (FRS). NASH patients were matched with non-NASH controls on age, sex, race/ethnicity, and diabetes status. Weighted logistic regression was conducted, modeling elevated predicted CV risk (binary) as the dependent variable and indicators for NASH / fibrosis stages as independent variables. A sample of 125 NASH patients was matched with 2585 controls. NASH with significant fibrosis was associated with elevated predicted 10-year CV risk, although this association was only statistically significant in PCE analyses (odds ratio and 95% CI 2.34 [1.25, 4.36]). Analyses restricting to ages <65 years showed similar results, with associations of greater magnitude. Independent of diabetes, a significant association was observed between NASH with significant liver fibrosis and predicted primary CV-event risk in US adults, particularly for those <65. These findings suggest the importance of accounting for NASH and liver-fibrosis stage in predicting CV-event risk.

Disentangling the Inverse LDL-C-hemorrhagic Stroke Association in Chinese Adults with Hypertension: Findings from the Chinese Multi-Provincial Cohort Study.

Why lower low-density lipoprotein cholesterol (LDL-C) was associated with a decreased atherosclerotic cardiovascular disease (ASCVD) risk but an increased hemorrhagic stroke (HS) risk in hypertensive adults remains unclear. We examined whether the inverse LDL-C-HS association partly arises from its effect on ASCVD. We estimated separable effects of LDL-C on HS outside (i.e., separable direct effect) or only through its effect on ASCVD (i.e., separable indirect effect) in hypertensive adults from the Chinese Multi-provincial Cohort Study. We quantified such effects using numbers needed to treat (NNT) to prevent or cause an extra HS based on the restricted mean event-free time till a 25-year follow-up. LDL-C $<$ 70 mg/dL was not associated with an increased HS risk compared to LDL-C $\ge$ 70 mg/dL regarding total and separable direct effects. However, a small separable indirect effect (i.e., NNT to harm: 9722 participants) was noted and validated via a series of sensitivity analyses. Moreover, modified effects were observed, particularly in the 35-49-year age group, men, and those with SBP $\ge$ 140 mm Hg. These results suggest the inverse LDL-C-HS association in hypertensive adults is partly due to its effect on ASCVD. A better understanding of such associations would provide more enlightening into stroke prevention.

The epigenetic mechanism of metabolic risk in bipolar disorder.

Bipolar disorder (BD) is a complex and severe mental illness that causes significant suffering to patients. In addition to the burden of depressive and manic symptoms, patients with BD are at an increased risk for metabolic syndrome (MetS). MetS includes factors associated with an increased risk of atherosclerotic cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM), which may increase the mortality rate of patients with BD. Several studies have suggested a link between BD and MetS, which may be explained at an epigenetic level. We have focused on epigenetic mechanisms to review the causes of metabolic risk in BD.

Design and rationale for a randomized, open-label, parallel clinical trial evaluating major adverse cardiovascular events (pharmacological treatment versus diet control) in patients with high-normal blood pressure: the PRINT-TAHA9 trial

BackgroundThe distinction between normal and high blood pressure remains a debated topic, with varying guidelines on when to start medication. Contemporary guidelines advocate for the initiation of antihypertensive therapy in individuals who present with high-normal blood pressure, particularly those exhibiting elevated 10-year atherosclerotic cardiovascular disease (ASCVD) risk scores. Despite these recommendations, there is a notable lack of direct evidence supporting the efficacy of treating high-normal blood pressure to prevent major adverse cardiovascular events (MACE).MethodsThe PRINT-TAHA9 trial, a unicentric, randomized, open-label, controlled, parallel clinical study, seeks to explore the effects of intensive blood pressure control on MACE in participants with high-normal blood pressure. We will enroll 1620 adults aged 18 years and above with a systolic blood pressure range of 130–140 mmHg, diastolic blood pressure under 90 mmHg, and atherosclerotic cardiovascular disease (ASCVD) risk score exceeding 7.5%. The study will be executed in five distinct phases, with each phase enrolling between 300 and 400 participants. Participants will be randomly assigned to either the treatment group receiving antihypertensive medication (amlodipine/valsartan) and a low-salt/low-fat diet or to the control group receiving a similar diet. Follow-up visits are scheduled every 6 months over a 3-year period to monitor blood pressure, evaluate medication adherence, document any adverse events, and adjust the intervention as necessary. Cox proportional hazards regression analysis will be employed to examine the disparities between the two arms.DiscussionDespite guidelines promoting early treatment of elevated blood pressure, the debate continues due to insufficient evidence that such interventions significantly reduce the occurrence of MACE. This trial seeks to address this critical evidence gap.Trial registrationThe PRINT-TAHA9 trial was registered in October 2019 with the Iranian Registry of Clinical Trials (IRCT.ir) under the registration number IRCT20191002044961N1. https://irct.behdasht.gov.ir/trial/43092.

Atherosclerotic cardiovascular disease following a diagnosis of idiopathic inflammatory myopathy: analysis from a retrospective cohort in the TriNetX registry.

Idiopathic inflammatory myopathies (IIM) confer an increased risk of morbidity from atherosclerotic cardiovascular disease (ASCVD). While ASCVD risk has been studied in other countries, these results may not be applicable to patients with dermatomyositis (DM) and polymyositis (PM) in the United States. This retrospective analysis of a cohort of patients identified by ICD code from TriNetX investigated the incidence of ASCVD after International Classification of Disease (ICD) codes of DM, PM, dermatopolymyositis (DPM) or juvenile dermatomyositis (JDM). Patients were identified by entry of two ICD codes separated by at least 6months, according to their first diagnosis code; ASCVD was defined as first ICD code for myocardial infarction, ischemic stroke, transient ischemic attack, or peripheral arterial disease. Cox proportional hazards regression modeled time from first IIM ICD code to ASCVD event. A total of 35,554 patients were identified with the mean age at first IIM code of 54 and 26.1% were male. The most common comorbidity for all groups except JDM was hyperlipidemia (39.9%) though 79.2% of patients were on no cholesterol lowering medication. ASCVD occurred in 30.4% of patients with PM, 24.3% of patients with DM and 0.9% of patients with JDM. Patients with PM had a median time to event of 9.7years (95% Confidence interval (CI) 9.1, 10.7) and 14.3years (95% CI 12.6, 14.8) for DM. This study demonstrates that ASCVD is a comorbidity occurring after a median of 12.5years (95% CI 11.9, 13.6) in patients with IIM. ASCVD appears to be a long-term complication for IIM patients occurring in nearly a quarter of US patients without prior ASCVD with at least two ICD codes for IIM, with a median time to event of 12.5years. There appears to be a practice gap in the recognition and treatment of hyperlipidemia in these patients. Key Points • Hyperlipidemia was a common comorbidity identified in patients with IIM though most patients were not on cholesterol lowering medication. • Development of ASCVD appears to be a long-term complication for patients with IIM in the United States.

Evaluation of infectious diseases physicians’ attitudes to dyslipidemia management in PLWH

ABSTRACT Objectives Dyslipidemia is a well-established risk factor for atherosclerotic cardiovascular disease (ASCVD). ASCVD prevalence among people living with HIV (PLWH) is twice that of the general population. This study aimed to evaluate the infectious diseases (ID) physicians’ attitudes on dyslipidemia management in PLWH. Methods This observational, cross-sectional study was conducted as online survey among ID physicians between November 2023 and February 2024. An e-mail with the survey link, title and purpose of the study was sent to physicians through the local ID societies. The survey included questions about physicians’ demographic characteristics and their attitudes toward treating dyslipidemia in PLWH. Results A total of 242 physicians responded to the survey, of whom 59.9% (n = 145) were ID specialists and 40.1% (n = 97) were ID residents. Forty-one percent (n = 100) of physicians reported that they did not follow a guideline, and 26% of physicians reported that they did not use a cardiovascular risk calculator in their clinical practice. Specialists (69%) were more likely than residents (43.3%) to follow clinical guidelines for dyslipidemia management (p < 0.001). Seventy-two percent (n = 174) of physicians doubted the need to treat dyslipidemia, and 73% (n = 177) of physicians were affected by the patient skepticism. Workload and lack of time were identified by 68.6% of physicians as barriers to implementing dyslipidemia guideline recommendations. Conclusion A considerable number of Turkish ID physicians did not prefer using clinical guidelines for dyslipidemia and ASCVD risk calculators. Statin prescribing of physicians was influenced by workload, lack of time, patient skepticism, and lack of knowledge. Training ID physicians in primary prevention of ASCVD and management of dyslipidemia in PLWH is paramount.

Association of Cardiac Troponin T With Coronary Atherosclerosis in Asymptomatic Primary Prevention People With HIV

BackgroundCoronary plaque is common among people with HIV (PWH) with low-to-moderate traditional atherosclerotic cardiovascular disease (ASCVD) risk. ObjectivesThe purpose of this study was to determine the association of high-sensitivity cardiac troponin T (hs-cTnT) levels with coronary plaque characteristics and evaluate if hs-cTnT improves identification of these features beyond traditional ASCVD risk factors among PWH. MethodsAmong PWH receiving stable antiretroviral therapy with low-to-moderate ASCVD risk and no known history of ASCVD, hs-cTnT levels and measures of plaque by coronary computed tomography angiography were assessed. Primary outcomes included the association of hs-cTnT level with the presence of any plaque, vulnerable plaque, coronary artery calcium (CAC) score, and Leaman score. Assessment of model discrimination of hs-cTnT for plaque characteristics was also performed. ResultsThe cohort included 708 U.S. participants with a mean age of 51 ± 6 years, 119 (17%) females, a median ASCVD risk score of 4.4% (Q1-Q3: 2.5%-6.6%), and a median hs-cTnT level of 6.7 ng/L (detectable level ≥6 ng/L in 61%). Any plaque was present in 341 (48%), vulnerable plaque in 155 (22%), CAC>100 in 68 (10%), and a Leaman score >5 in 105 (15%). After adjustment for ASCVD risk score, participants with hs-cTnT >9.6 ng/L (highest category) versus an undetectable level (<6 ng/L) had a greater relative risk for any plaque (1.37, 95% CI: 1.12-1.67), vulnerable plaque (1.47, 95% CI: 1.16-1.87), CAC>100 (2.58, 95% CI: 1.37-4.83), and Leaman score >5 (2.13, 95% CI: 1.32-3.46). The addition of hs-cTnT level modestly improved the discrimination of ASCVD risk score to identify critical plaque features. ConclusionsIn PWH without known ASCVD, hs-cTnT levels were strongly associated with and improved prediction of subclinical coronary plaque.

Lipoprotein(a) is a highly atherogenic lipoprotein: pathophysiological basis and clinical implications.

Lipoprotein(a) has been identified as a causal risk factor for atherosclerotic cardiovascular disease (ASCVD) and aortic valve stenosis. However, as reviewed here, there is ongoing debate as to the key pathogenic features of Lp(a) particles and the degree of Lp(a) atherogenicity relative to low-density lipoprotein (LDL). Genetic analyses have revealed that Lp(a) on a per-particle basis is markedly (about six-fold) more atherogenic than LDL. Oxidized phospholipids carried on Lp(a) have been found to have substantial pro-inflammatory properties triggering pathways that may contribute to atherogenesis. Whether the strength of association of Lp(a) with ASCVD risk is dependent on inflammatory status is a matter of current debate and is critical to implementing intervention strategies. Contradictory reports continue to appear, but most recent studies in large cohorts indicate that the relationship of Lp(a) to risk is independent of C-reactive protein level. Lp(a) is a highly atherogenic lipoprotein and a viable target for intervention in a significant proportion of the general population. Better understanding the basis of its enhanced atherogenicity is important for risk assessment and interpreting intervention trials.
