Higher Risk Of Myocardial Infarction Research Articles

Co-exposure to multiple air pollutants, genetic susceptibility, and the risk of myocardial infarction onset: a cohort analysis of the UK Biobank participants.

The relationship between the long-term joint exposure to ambient air pollution and incidence of myocardial infarction (MI) and modification by genetic susceptibility remain inconclusive. We analysed 329 189 UK Biobank participants without MI at baseline. Exposure concentrations to particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), and nitrogen oxides (NOx) were obtained. Air pollution score assessing the joint exposure was calculated, and its association with MI was evaluated via Cox model under the P value aggregation framework. Genetic susceptibility to MI was evaluated by incorporating polygenic risk score (PRS) into models. Risk prediction models were also established. During a median follow-up of 13.4 years, 9993 participants developed MI. Per interquartile range increase of PM2.5, PM10, NO2, and NOx resulted in 74% [95% confidence intervals (CIs) 69%-79%], 67% (63%-72%), 46% (42%-49%), and 38% (35%-41%) higher risk of MI. Compared with the lowest quartile (Q1) of air pollution score, the multivariable adjusted hazard ratio (HR) (95%CIs) of Q4 (the highest cumulative air pollution) was 3.50 (3.29-3.72) for MI. Participants with the highest PRS and air pollution score possessed the highest risk of incident MI (HR = 4.88, 95%CIs 4.35-5.47). Integrating PRS, air pollution exposure, and traditional factors substantially improved risk prediction of MI. Long-term joint exposure to air pollutants including PM2.5, PM10, NO2, and NOx is substantially associated with increased risk of MI. Genetic susceptibility to MI strengthens such adverse joint association. Air pollutions together with genetic and traditional factors enhance the accuracy of MI risk prediction.

Causal Association Between Subtypes of Excessive Daytime Sleepiness and Risk of Cardiovascular Diseases.

Excessive daytime sleepiness (EDS), experienced in 10% to 20% of the population, has been associated with cardiovascular disease and death. However, the condition is heterogeneous and is prevalent in individuals having short and long sleep duration. We sought to clarify the relationship between sleep duration subtypes of EDS with cardiovascular outcomes, accounting for these subtypes. We defined 3 sleep duration subtypes of excessive daytime sleepiness: normal (6-9 hours), short (<6 hours), and long (>9 hours), and compared these with a nonsleepy, normal-sleep-duration reference group. We analyzed their associations with incident myocardial infarction (MI) and stroke using medical records of 355 901 UK Biobank participants and performed 2-sample Mendelian randomization for each outcome. Compared with healthy sleep, long-sleep EDS was associated with an 83% increased rate of MI (hazard ratio, 1.83 [95% CI, 1.21-2.77]) during 8.2-year median follow-up, adjusting for multiple health and sociodemographic factors. Mendelian randomization analysis provided supporting evidence of a causal role for a genetic long-sleep EDS subtype in MI (inverse-variance weighted β=1.995, P=0.001). In contrast, we did not find evidence that other subtypes of EDS were associated with incident MI or any associations with stroke (P>0.05). Our study suggests the previous evidence linking EDS with increased cardiovascular disease risk may be primarily driven by the effect of its long-sleep subtype on higher risk of MI. Underlying mechanisms remain to be investigated but may involve sleep irregularity and circadian disruption, suggesting a need for novel interventions in this population.

Opposite causal effects of birthweight on myocardial infarction and atrial fibrillation and the distinct mediating pathways: a Mendelian randomization study

BackgroundPrevious observational studies have documented an inverse association of birthweight with myocardial infarction (MI) but a positive association with atrial fibrillation (AF). However, the causality of these associations and the underlying mediating pathways remain unclear. We aimed to investigate the causal effects of birthweight, incorporating both fetal and maternal genetic effects, on MI and AF, and identify potential mediators in their respective pathways.MethodsWe performed Mendelian randomization (MR) analyses using genome-wide association study summary statistics for birthweight (N = 297,356 for own birthweight and 210,248 for offspring birthweight), MI (Ncase=61,000, Ncontrol=577,000), AF (Ncase=60,620, Ncontrol=970,216), and 52 candidate mediators (N = 13,848-1,295,946). Two-step MR was employed to identify and assess the mediation proportion of potential mediators in the associations of birthweight with MI and AF, respectively. As a complement, we replicated analyses for fetal-specific birthweight and maternal-specific birthweight.ResultsGenetically determined each 1-SD lower birthweight was associated with a 40% (95% CI: 1.22–1.60) higher risk of MI, whereas each 1-SD higher birthweight was causally associated with a 29% (95% CI: 1.16–1.44) higher risk of AF. Cardiometabolic factors, including lipids and lipoproteins, glucose and insulin, blood pressure, and fatty acids, each mediated 4.09-23.71% of the total effect of birthweight on MI, followed by body composition and strength traits (i.e., appendicular lean mass, height, and grip strength) and socioeconomic indicators (i.e., education and household income), with the mediation proportion for each factor ranging from 8.08 to 16.80%. By contrast, appendicular lean mass, height, waist circumference, childhood obesity, and body mass index each mediated 15.03-45.12% of the total effect of birthweight on AF. Both fetal-specific birthweight and maternal-specific birthweight were inversely associated with MI, while only fetal-specific birthweight was positively associated with AF. Psychological well-being and lifestyle factors conferred no mediating effect in either association.ConclusionsCardiometabolic factors mainly mediated the association between lower birthweight and MI, while body composition and strength traits mediated the association between higher birthweight and AF. These findings provide novel evidence for the distinct pathogenesis of MI and AF and advocate adopting a life-course approach to improving fetal development and subsequent causal mediators to mitigate the prevalence and burden of cardiovascular diseases.

Association between Parkinson's disease and the risk of adverse cardiovascular events: a systematic review and meta-analysis.

This review aims to examine the association of Parkinson's disease (PD) with the increased risk of cardiovascular events. PubMed, Embase, CENTRAL, and Scopus databases were electronically searched for papers published up to 5 May 2023. Studies reporting the association between PD and the subsequent risks of stroke, myocardial infarction (MI), and cardiovascular mortality were included. Sixteen studies were included in this review. The clinical data of 101,712 PD patients were compared with that of the control group of 204,901 patients without PD in the included studies. Meta-analysis showed that PD patients had an increased risk of stroke compared with patients without PD (odds ratio (OR): 1.49; 95% confidence interval (CI): 1.30, 1.72; I2 = 76%). The pooled analysis demonstrated no significant increase in the risk of MI (OR: 1.16; 95% CI: 0.85, 1.59; I2 = 82%) and cardiovascular mortality (OR: 1.20; 95% CI: 0.93, 1.54; I2 = 65%) in PD patients. However, data from cohort studies indicated a possibility of higher risk of MI (OR: 1.36; 95% CI: 1.01, 1.84; I2 = 80%) and cardiovascular mortality (OR: 1.22; 95% CI: 1.00, 1.60; I2 = 62%) in patients with PD. Patients with PD may have an increased risk of stroke as compared with the age- and gender-matched general population. While our results show that PD does not increase the overall risk of MI and cardiovascular mortality, analysis of cohort studies alone demonstrated that these risks may be higher in patients with PD. The current evidence is of very low quality. Further prospective cohort studies from different countries that would account for important cardiovascular risk factors are needed to improve the current evidence. https://www.crd.york.ac.uk/prospero/, PROSPERO (CRD42023421924).

Generation of induced pluripotent stem cell lines from South Asian ethnicity

South Asians, which represent around 25% of the world’s population, have a disproportionately high risk of cardiometabolic disease, two-fold higher risk of myocardial infarction, and 4- to 6-fold higher risk for diabetes compared to Caucasians. We generated two induced pluripotent stem cell (iPSC) lines from healthy South Asian donors and validated the pluripotency and ability of these cell lines to differentiate into three germ layers. These iPSC lines can be applied to generate many cardiovascular cell types such as cardiomyocytes, endothelial cells, and mural cells to investigate different cardiovascular disease mechanisms triggered by environmental risk factors or drugs in vitro.

Apolipoproteins as predictors of cardiovascular risk in patients with chronic pancreatitis.

Patients with pancreatic diseases are at increased risk of cardiovascular events. Investigating various apolipoprotein forms as important atherogenesis components may improve cardiovascular risk (CVR) prediction. This study aimed to investigate CVR factors in patients with chronic pancreatitis. The study enrolled 70 patients (40 males and 30 females, mean age 55.2 years) with chronic pancreatitis and treated pancreatic exocrine insufficiency. We assessed CVR by apolipoproteins A-I, A-II, B, and C-III, lipid profile; score systems [SCORE risk chart and Framingham Risk Score (FRS)], diabetes mellitus; chronic pancreatitis by M-ANNHEIM classification. Statistics were performed via SPSS v. 22. Low apolipoprotein A-I and high apolipoprotein B levels with increased atherogenic potential were observed in 37 and 26 patients. 45.71% demonstrated a high risk of myocardial infarction with high apolipoprotein B/apolipoprotein A-I ratio. Men are at higher CVR risk. Apolipoproteins A-I and A-II correlated with the cardioprotective high-density lipoprotein (HDL) in contrast to apolipoproteins B and C-III, which correlated strongly with low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides (TG). Increased CVR assessed by FRS correlated with significantly lower apolipoprotein A-I and higher apolipoprotein B and apolipoprotein B/apolipoprotein A-I ratio. With the increase in chronic pancreatitis severity, we observed decreased apolipoproteins and increased apolipoprotein B/apolipoprotein A-I ratio. Apolipoproteins are valuable CVR indicators. Further studies are required to establish a CVR screening panel in this population.

Do patients with bipolar disorders have an increased risk of myocardial infarction? A systematic review and meta-analysis.

Research shows that patients with bipolar disorders (BD) may have an altered risk of cardiovascular diseases; however, the association between the two is not clear. In this study, we reviewed evidence on the association between BD and subsequent risk of myocardial infarction (MI). Studies published on PubMed, Embase, Scopus, CENTRAL, and Web of Science were identified up to 30th August 2023. Random-effects meta-analysis was done to calculate the pooled odds ratio (OR). A total of six studies with 19,862,894 individuals were included. Of these, 46,627 were diagnosed with BD (0.23%). The median follow-up of the studies varied from 7.6 to 20 years. Meta-analysis of all six studies showed that BD patients do not have a higher risk of MI as compared to the general population (OR: 1.36, 95% CI: 0.99, 1.86). The overall analysis had substantial heterogeneity with I2=86%. No publication bias was noted among the studies. Results did not change during sensitivity analysis. Current evidence fails to show an association between BD and subsequent risk of MI. The high heterogeneity in the meta-analysis and lack of adjustment of all important confounders are significant limitations that need to be overcome by future studies.

Sacubitril/valsartan compared to ramipril in high-risk post-myocardial infarction patients stratified according to use of mineralocorticoid receptor antagonists: Insight from the PARADISE MI trial.

It is unknown whether safety and clinical endpoints by use of sacubitril/valsartan (an angiotensin receptor-neprilysin inhibitor [ARNI]) are affected by mineralocorticoid receptor antagonists (MRA) in high-risk myocardial infarction (MI) patients. The aim of this study was to examine whether MRA modifies safety and clinical endpoints by use of sacubitril/valsartan in patients with a MI and left ventricular systolic dysfunction (LVSD) and/or pulmonary congestion. Patients (n = 5661) included in the PARADISE MI trial (Prospective ARNI vs. ACE Inhibitor Trial to Determine Superiority in Reducing Heart Failure Events After MI) were stratified according to MRA. Primary outcomes in this substudy were worsening heart failure or cardiovascular death. Safety was defined as symptomatic hypotension, hyperkalaemia >5.5 mmol/L, or permanent drug discontinuation. A total of 2338 patients (41%) were treated with MRA. Safety of ARNI compared to ramipril was not altered significantly by ± MRA, and both groups had similar increase in symptomatic hypotension with ARNI. In patients taking MRA, the risk of hyperkalaemia or permanent drug discontinuation was not significantly altered by ARNI (p > 0.05 for all comparisons). The effect of ARNI compared with ramipril was similar in those who were and were not taking MRA (hazard ratio [HR]MRA 0.96, 95% confidence interval [CI] 0.77-1.19 and HRMRA- 0.87, 95% CI 0.71-1.05, for the primary endpoint; p = 0.51 for interaction [Clinical Endpoint Committee adjudicated]); similar findings were observed if investigator-reported endpoints were evaluated (p = 0.61 for interaction). Use of a MRA did not modify safety or clinical endpoints related to initiation of ARNI compared to ramipril in the post-MI setting in patients with LVSD and/or congestion.

Cardiovascular Prognosis in Patients with Peripheral Artery Disease and Approach to Therapy.

Peripheral artery disease (PAD), the pathophysiologic narrowing of the arterial blood vessels of the lower limbs due to atherosclerosis, is estimated to affect more than 200 million people worldwide and its prevalence ranges from 0.9 to 31.3% in people aged ≥50 years. It is an established marker of systemic obstructive atherosclerosis, which depicts patients at higher risk of myocardial infarction and stroke, due to the involvement of coronary and cerebral arteries in the atherosclerotic process. Therefore, identifying PAD, particularly in patients with coronary artery disease, is important to assess the cardiovascular risk score and implement specific therapies and prevention strategies. Since PAD emerged as an important clinical cardiovascular predictor, even more than other typical cardiovascular risk factors, an aggressive strategy to identify and treat PAD patients should be pursued by general practitioners, cardiologists, and vascular surgeons; similarly, preventive strategies should be implemented to improve prognosis and outcomes, particularly in patients suffering from both coronary artery disease and PAD. In this review, we describe the pathophysiology, including limb vasoconstriction after coronary angioplasty, the diagnosis of PAD, prognosis according to cardiovascular events, coronary artery disease, and heart failure. Furthermore, a large section of this review is on management, which spans from risk factors' modification to antithrombotic therapy, and revascularization is provided. Finally, considerations about newer therapeutic options for the "desert foot" are discussed, including gene therapy.

Meta-Analysis on the Impact of Inflammatory Rheumatological Conditions on Outcomes Following Acute Coronary Syndrome.

Inflammatory rheumatological conditions, also known as inflammatory rheumatic conditions (IRC), constitute a category of autoimmune and inflammatory ailments primarily affecting the musculoskeletal system, encompassing the joints, muscles, and connective tissues. The objective of this meta-analysis is to evaluate the impact of inflammatory rheumatological conditions (IRC) on post-acute coronary syndrome (ACS) outcomes.This study was performed as per the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. The PubMed, Web of Science, and Scopus databases were searched by two authors without any language constraints from January 1, 2015, to October 15, 2023. The primary outcome assessed in this meta-analysis was all-cause mortality. Other outcomes included myocardial infarction and revascularization. A total of 11 studies were included in this meta-analysis. The risk of all-cause mortality was significantly higher in patients with IRC compared to non-IRC patients (RR: 1.12, 95% CI: 1.00 to 1.26, p-value: 0.04). There is a significantly higher risk of myocardial infarction and revascularization in patients with IRC as opposed to those without IRC. Furthermore, while there was a higher risk of stroke in the IRC group compared to the non-IRC group, this disparity did not reach statistical significance. Future research should focus on specific inflammatory rheumatoid conditions, a comprehensive evaluation of cardiovascular events, and targeted interventions to enhance patient outcomes in this vulnerable population.

Risk of myocardial infarction, heart failure, and cerebrovascular disease with the use of valsartan, losartan, irbesartan, and telmisartan in patients.

There is a lack of studies comparing the risk of cardio-cerebrovascular disease between angiotensin receptor blockers (ARBs) of different half-lives. We aimed to compare the risks of myocardial infarction (MI), heart failure (HF), and cerebrovascular disease with the use of valsartan, losartan, irbesartan, and telmisartan with different half-lives in a national claim-based retrospective cohort of patients aged ≥ 40 years with hypertension. To establish a cohort exposed to valsartan, losartan, irbesartan, or telmisartan, we performed propensity score (PS) matching and used an as-treated approach to evaluate exposure. The Cox regression model was employed to calculate hazard ratios, which were based on the incidence rate for each newly occurring event of MI, heart failure, or cerebrovascular disease. These hazard ratios were calculated to compare the risk of MI, heart failure, and cerebrovascular disease associated with valsartan, losartan, and irbesartan in comparison to telmisartan. A PS-matched cohort of 148,229 patients was established for each of valsartan, losartan, irbesartan, or telmisartan. The matched cohort analysis showed that the adjusted hazard ratio (aHRs, 95% confidence interval) for MI was higher for valsartan use (1.39, 1.33-1.45) and losartan use (1.10, 1.05-1.15) but lower for irbesartan use (0.90, 0.86-0.94) compared with the reference (telmisartan). The aHRs for HF were not different among these ARBs (angiotensin receptor blockers). The aHR for cerebrovascular disease was lower for valsartan use (0.85, 0.83-0.87) and losartan use (0.80, 0.78-0.82) but higher for irbesartan use (1.11, 1.09-1.13) compared with the reference. We found differences in the risk of MI and cerebrovascular disease with the use of different ARBs compared to telmisartan use. Valsartan, and losartan with a short half-life, which showed a higher risk of MI, had a lower risk of cerebrovascular disease. Conversely, irbesartan with a long half-life, which showed a lower risk of MI, had a higher risk of cerebrovascular disease.

Clinical outcomes of comparison between type-III cap and non-cap acute coronary syndrome patients in 3 year follow up

Abstract Background Coronary artery perforation(CAP) is potentially fatal complication of percutaneous coronary intervention(PCI) in acute coronary syndrome(ACS).There is no study in literature comparing long term clinical outcomes of type III-CAP-ACS and non-CAP-ACS patients. Purpose The aim of this study was to investigate in hospital- 1-year and 3-year clinical outcomes of type III-CAP during PCI in ACS patients. Methods Data from ACS patients who had type III-CAP during PCI from January 2010 to Jaunary 2020 at different high volume centers in Turkey were collected.A retrospective cohort of 43,791 patients who underwent PCI was used:120 patients with CAP and 43,671 case-control patients were evaluated.Propensity score matching was used to evaluate the association between differing CAP. Clinical angiographic and procedural characteristics, their management and outcomes were analyzed retrospectively in 1-year and 3-year follow up.Multiple regressions were used to identify predictors of coronary perforation and its association with outcomes. Results The mean age of subjects was 66.5±11.9 years(61.8%males).Of all ACS patients were 247STEMI(37.9%), 216NSTEMI(33.2%) and 188UA(28.9%).Non significant differences were identified between the CAP and non-CAP groups in hospital follow-up for, cardiac death, major bleeding, and stent thrombosis except cerebrovascular event(p=0.003).At three year, differences remained different between myocardial infarction(MI)(p=0.038),coronary artery bypass graft(CABG)(p=0.001),stent thrombosis(ST)(p=0.002),major bleeding(p=0.029) and cerebrovascular event(CVE)(p=0.011)), was observed in the CAP/non-CAP group.Median follow-up of was 36 months.The all-cause mortality was 33.3% in CAP group versus 1.8% in non-CAP group at 1-year and 28.3% in CAP group versus 6.9% in non-CAP group at 3-years(p=0.001,p=0.001). Conclusions There was no significat difference between type-III-CAP and non-CAP group in hospital mortality.The procedural, clinical, 1 and 3-year outcomes of type III-CAP showed that relatively high risk of MI,CABG,CVE,ST and major bleeding under 1 and 3-year follow-up.Also, non-CAP ACS patients had better survival compared to type III CAP ACS patients in 3- year follow up.Figure 1Figure 2

Abstract 15993: The Association of Aspirin With and Without Statin on Cardiovascular Outcomes in Primary Prevention Patients With Diabetes Mellitus

Background: The role of aspirin in primary prevention of ASCVD amongst high-risk individuals with diabetes mellitus remains unclear. We investigated aspirin use with and without statin and its association with future ASCVD events in a cohort of real-world primary prevention patients with diabetes mellitus. Methods: Primary prevention patients with diabetes were stratified based on HbA1c levels (6.5-7%, 7-9%, &gt;9%) and 10-year ASCVD risk (High-risk [≥20%]). Aspirin use was defined as no use, seldom used (&lt;30% of the time), sometimes used (≥30% - &lt; 70% of the time), and often used (≥70% of the time). Cox regression assessed HRs of myocardial infarction (MI), stroke, and mortality with aspirin use. Results: Of 79, 597 patients with diabetes, 44.6% were classified as high-risk. These patients showed highest utilization of aspirin (45.7%) and statin (44.9%). Compared to high-risk patients with diabetes and an HbA1c of &gt;9% on both a statin and an aspirin, those on statin alone had higher risk of MI [HR MI 1.74 (1.44-2.212), p &lt;0.001], ischemic stroke [HR STROKE 2.52 (1.92-3.29), p &lt;0.001], and mortality [HR 1.67 (1.27-2.19), p &lt;0.001] (Table). Aspirin use alone was associated with higher risk of MI [HR 3.11 (2.42-4.00), p &lt;0.001], ischemic stroke [HR 3.12 (2.08-4.67), p &lt;0.001], and mortality [HR 3.77 (2.71-5.23), p &lt; 0.0004] in the high-risk population with HbA1c &gt;9% (Table). At all A1c levels, patients on no statin or aspirin were at significantly higher risk for MI, stroke, and mortality (Table). In high-risk patients with an HbA1c &gt;9%, ASA use ≥ 70% resulted in significantly lower risk of MI [HR 0.58 (0.49-0.69), p&lt;0.001)], ischemic stroke [HR 0.36 (0.28-0.46), p&lt;0.001] and mortality [HR 0.52 (0.42-0.66), p&lt;0.001]. Conclusion: Low dose aspirin may play a role in prevention of ASCVD events in high-risk patients with diabetes. Future studies can clarify the risk-benefit ratio of using aspirin with statin in patients with poor glycemic control for primary prevention of ASCVD events.

Abstract 18200: Prognostic Importance of Serial NT-proBNP Measurements Following High-Risk Mi: The PARADISE-MI Trial

Introduction: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a potent predictor of heart failure (HF) and death following myocardial infarction (MI). NT-proBNP levels change post MI. Hypothesis: Serial measurements of NT-proBNP add prognostic information. Aims: To investigate the prognostic importance of NT-proBNP two weeks after MI in PARADISE-MI and to identify predictors of week 2 NT-proBNP. Methods: Patients with MI and LVEF ≤40% and/or pulmonary congestion (n=5661) were randomized to sacubitril/valsartan or ramipril. Patients with NT-proBNP measured at week 2 (n=1057) were analyzed. Associations of week 2 NT-proBNP with subsequent clinical outcomes were evaluated with Cox models adjusted for baseline NT-proBNP, age, sex, atrial fibrillation (AF), LVEF, STEMI presentation, BMI, eGFR, high-sensitivity troponin T (hs-cTnT), time from presentation to randomization and treatment assignment. Results: Median NT-proBNP was 1425 [685, 2598] ng/L at week 2, declining 23% (95% CI, 20-26%) from baseline. Patients in the highest NT-proBNP quartile at week 2 (≥2616 ng/L) were older, had lower LVEF and eGFR, higher Killip class, more AF, and higher baseline NT-proBNP (all p≤0.05). Higher NT-proBNP at week 2 was independently associated with greater risk of CV death or incident HF (adjusted HR [aHR] 1.62 per log2; 95% CI, 1.30-2.03), HF hospitalization (aHR 1.96; 95% CI, 1.46-2.62) and all-cause death (aHR 1.86; 95% CI, 1.40-2.47). Higher baseline NT-proBNP and hs-cTnT, longer interval between presentation and randomization and female sex were associated with higher week 2 NT-proBNP levels while sacubitril/valsartan was associated with lower levels (Table). Conclusions: Patients with elevated NT-proBNP two weeks after high-risk MI are at greater risk of subsequent death or incident HF, even after adjusting for baseline level. Higher baseline NT-proBNP and hs-cTnT are predictive of higher week 2 NT-proBNP while sacubitril/valsartan decreases levels.

Abstract 16212: Sex-Based Statin Utilization and Cardiovascular Disease Outcomes: A Real World Secondary Prevention Cohort

Introduction: Current guidelines recommend using high-intensity statins in patients with clinical ASCVD.However, real world adherence to GDSI use and recurrent events remains less known. Sex difference in statin use have been previously reported. We evaluated sex-based disparities in GDSI use and recurrent ASCVD outcomes in a large healthcare network. Methods: Using EMR, we assessed statin use and intensity amongst patients with established prior ASCVD events (MI, ischemic stroke/TIA) and PAD from 2010-2022. Statins were categorized into GDSI (high intensity), &lt;gdsi (moderate="" or="" low="" intensity)="" or no statin use. Outcomes of interest included repeat MI, stroke/TIA and all-cause mortality. Incident rates (IR) and Cox regression hazard ratios (HR) of ASCVD outcomes were calculated across statin categories stratified by sex. Results: Amongst 45,949 patients,31% were women. Women had more diabetes (29% vs 24%) and higher LDL-C (94.9 ± 40.8 vs 87.6 ± 37.1 mg/dL) than men. During a follow-up period of 5 years, women were less likely to be started on GDSI (61.6% vs 65.8%, p&lt;0.01) and achieve LDL-C&lt;70mg/dL (41% vs and 49%, p&lt;0.01) as compared to men. GDSI use lowered IRs for all outcomes in both sexes (Table 1). Women on GDSI had higher risk of MI (HR 1.21 [1.12-1.31)],stroke (1.21 [1.08-1.34] and mortality (1.12 [1.05-1.20]), all p&lt;0.01) than men. Conclusions: In a contemporary cohort of secondary prevention patients, women were less likely to be prescribed GDSI than men and less likely to achieve guideline concordant LDL-C&lt;70mg/dL. This was associated with a higher risk of recurrent ASCVD events in women as compared to men. More sex specific interventions are needed to ensure adequate preventive treatment for both sexes.

Long-Term Cumulative Exposure to High γ-Glutamyl Transferase Levels and the Risk of Cardiovascular Disease: A Nationwide Population-Based Cohort Study.

Elevated γ-glutamyl transferase (γ-GTP) levels are associated with metabolic syndrome. We investigated the association of cumulative exposure to high γ-GTP with the risk of cardiovascular disease (CVD) in a large-scale population. Using nationally representative data from the Korean National Health Insurance system, 1,640,127 people with 4 years of consecutive γ-GTP measurements from 2009 to 2012 were included and followed up until the end of 2019. For each year of the study period, participants were grouped by the number of exposures to the highest γ-GTP quartile (0-4), and the sum of quartiles (0-12) was defined as cumulative γ-GTP exposure. The hazard ratio for CVD was evaluated using the Cox proportional hazards model. During the 6.4 years of follow-up, there were 15,980 cases (0.97%) of myocardial infarction (MI), 14,563 (0.89%) of stroke, 29,717 (1.81%) of CVD, and 25,916 (1.58%) of death. Persistent exposure to high γ-GTP levels was associated with higher risks of MI, stroke, CVD, and death than those without such exposure. The risks of MI, stroke, CVD, and mortality increased in a dose-dependent manner according to total cumulative γ-GTP (all P for trend <0.0001). Subjects younger than 65 years, with a body mass index <25 kg/m2, and without hypertension or fatty liver showed a stronger relationship between cumulative γ-GTP and the incidence of MI, CVD, and death. Cumulative γ-GTP elevation is associated with CVD. γ-GTP could be more widely used as an early marker of CVD risk, especially in individuals without traditional CVD risk factors.

FRI529 Hypothyroidism And Systemic Lupus Erythematosus: A Nationwide Analysis

Abstract Disclosure: F. Sami: None. S. Sami: None. A. Razok: None. T. Ayub: None. A. Olafimihan: None. Background: Hypothyroidism is the most common thyroid disease in Systemic Lupus Erythematosus (SLE) and more prevalent in SLE than the general population. Our aim is to study the prevalence, epidemiology and likelihood of hypothyroidism with SLE as well as impact on outcomes and healthcare burden. Methods: The National Inpatient Database from 2016-2019 was used to extract patient populations. Data was stratified to reflect national estimates. Adult patients with principal diagnosis of SLE and hypothyroidism as a primary or secondary diagnosis were identified. Epidemiology was compared. We analyzed mortality rates, hospital charges (THC) and length of stay (LOS). Secondary outcomes included sepsis, congestive heart failure (CHF), renal and respiratory failure, stroke and myocardial infarction (MI). Statistical analysis was performed with STATA17. Univariate and multivariate regression analyses adjusted for confounders. Results: Among 721,090 adult SLE patients, 17.64% had hypothyroidism. In SLE-hypothyroid group, there were more females (93.46% vs 87.35%, odds ratio 2.01) and whites ( 65.82%vs 33.53%, OR 2.37). The mean age was higher (59.95 SD 15.56 vs 50.91 SD 16.94, P-value 0.000) with significantly more patients in 60-80 years group (44.64% vs 28.56%) and less in 18-40 year age group (1.68% vs 29.01%). African-Americans and Hispanics were significantly less in hypothyroid group with OR 0.34 and 0.87 respectively. Charlson comorbidity Index was ssignificantly high (3.2 vs 2.97). Hypothyroidism was significantly more among higher socioeconomic class of SLE patients (20.62% vs 16.7%) and less prevalent among the low socioeconomic class (28.88% vs 35.36%) based on annual income. There was no significant rise in mortality when adjusted for confounders (1.93% vs 1.97%, P-value 0.702), mean length of stay (5.41 vs 5.46, P-value 0.284), or total hospital charges ($63372 vs 64065, P-value 0.273) between two groups. There was a significantly higher prevalence of MI (3.21% vs 2.9%, P-value 0.01,OR 1.11) and CHF (5.94% vs 5%, P-value 0.00,OR 1.2). Prevalence of sepsis (8.92% vs 8.77%, P-value 0.449), renal failure (37.94% vs 37.79%), respiratory failure (37.63% vs 37.84%) and stroke (0.88% vs 0.93%,) was comparable with no significant difference. Odds ratio for hypothyroidism in SLE was 1.5, p-value 0.000. Conclusion: SLE patients with hypothyroidism are more females, Caucasians, of higher mean age, between 60-80 years of age, and from higher socioeconomic status. There is no effect on mortality, LOS and THC, rate of sepsis, stroke, renal and respiratory failure with hypothyroidism. There is a significantly higher risk of MI and CHF. SLE patients have 1.5 times increased risk of developing hypothyroidism. This emphasizes screening at-risk individuals when suspicion arises, for timely diagnoses and improving outcomes.

Increased risk of myocardial infarction in amyotrophic lateral sclerosis: A nationwide cohort study in South Korea

BackgroundThe risk of myocardial infarction (MI), the major form of CVD, in amyotrophic lateral sclerosis (ALS) is currently unknown. We investigated the risk of MI in ALS and analyzed the effect of ALS-related physical disability on the risk of MI using the Korean National Health Insurance Service database. MethodsA total of 659 ALS patients and 10,927 non-ALS participants were finally selected between January 1, 2011, and December 31, 2015. A Cox hazard regression model was used to examine the hazard ratios (HRs) for MI in ALS after adjustment for potential confounders. ResultsThe incidence rate of MI was 26.2 per 1000 person-years, and the adjusted HR (aHR) for MI in ALS patients was 10.6 (95% confidence interval [CI] 7.2–15.4) compared with the controls. ALS patients who developed physical disability had an even higher risk of MI (aHR 18.6, 95% CI 11.5–30.0) compared with those who did not develop disability (aHR 7.4, 95% CI 4.6–11.9). The increased risk of MI was more prominent in female subjects than in male subjects (aHR 17.8, 95% CI 10.8–29.4 vs. aHR 6.9, 95% CI 4.1–11.6, P for interaction 0.006) and in obese subjects than in non-obese subjects (aHR 17.8, 95% CI 10.5–30.1 vs. aHR 7.9, 95% CI 4.9–12.8, P for interaction 0.018). ConclusionsOur findings suggest that the risk of MI is high in ALS patients compared with a control population, and the risk is more prominent in those who develop physical disability, or who are female or obese.

Effectiveness and Safety of Enteric-Coated vs Uncoated Aspirin in Patients With Cardiovascular Disease

Clinicians recommend enteric-coated aspirin to decrease gastrointestinal bleeding in secondary prevention of coronary artery disease even though studies suggest platelet inhibition is decreased with enteric-coated vs uncoated aspirin formulations. To assess whether receipt of enteric-coated vs uncoated aspirin is associated with effectiveness or safety outcomes. This is a post hoc secondary analysis of ADAPTABLE (Aspirin Dosing: A Patient-Centric Trial Assessing Benefits and Long-term Effectiveness), a pragmatic study of 15 076 patients with atherosclerotic cardiovascular disease having data in the National Patient-Centered Clinical Research Network. Patients were enrolled from April 19, 2016, through June 30, 2020, and randomly assigned to receive high (325 mg) vs low (81 mg) doses of daily aspirin. The present analysis assessed the effectiveness and safety of enteric-coated vs uncoated aspirin among those participants who reported aspirin formulation at baseline. Data were analyzed from November 11, 2019, to July 3, 2023. ADAPTABLE participants were regrouped according to aspirin formulation self-reported at baseline, with a median (IQR) follow-up of 26.2 (19.8-35.4) months. The primary effectiveness end point was the cumulative incidence of the composite of myocardial infarction, stroke, or death from any cause, and the primary safety end point was major bleeding events (hospitalization for a bleeding event with use of a blood product or intracranial hemorrhage). Cumulative incidence at median follow-up for primary effectiveness and primary safety end points was compared between participants taking enteric-coated or uncoated aspirin using unadjusted and multivariable Cox proportional hazards models. All analyses were conducted for the intention-to-treat population. Baseline aspirin formulation used in ADAPTABLE was self-reported for 10 678 participants (median [IQR] age, 68.0 [61.3-73.7] years; 7285 men [68.2%]), of whom 7366 (69.0%) took enteric-coated aspirin and 3312 (31.0%) took uncoated aspirin. No significant difference in effectiveness (adjusted hazard ratio [AHR], 0.94; 95% CI, 0.80-1.09; P = .40) or safety (AHR, 0.82; 95% CI, 0.49-1.37; P = .46) outcomes between the enteric-coated aspirin and uncoated aspirin cohorts was found. Within enteric-coated aspirin and uncoated aspirin, aspirin dose had no association with effectiveness (enteric-coated aspirin AHR, 1.13; 95% CI, 0.88-1.45 and uncoated aspirin AHR, 0.99; 95% CI, 0.83-1.18; interaction P = .41) or safety (enteric-coated aspirin AHR, 2.37; 95% CI, 1.02-5.50 and uncoated aspirin AHR, 0.89; 95% CI, 0.49-1.64; interaction P = .07). In this post hoc secondary analysis of the ADAPTABLE randomized clinical trial, enteric-coated aspirin was not associated with significantly higher risk of myocardial infarction, stroke, or death or with lower bleeding risk compared with uncoated aspirin, regardless of dose, although a reduction in bleeding with enteric-coated aspirin cannot be excluded. More research is needed to confirm whether enteric-coated aspirin formulations or newer formulations will improve outcomes in this population. ClinicalTrials.gov Identifier: NCT02697916.

Incidence of Cardiovascular Disease and Venous Thromboembolism in Patients With Atopic Dermatitis.

Atopic dermatitis (AD) may increase risk for atherothrombotic and cardiovascular (CV) disease. Determine CV disease and venous thromboembolism risk among patients with AD. Cohort study using electronic health data from U.K. general practices in 1994 to 2015. Children (<18 y) and adults (≥18 y) with AD were matched to patients without AD on age, same practice, and encounter date. Treatments and specialist referrals served as proxies of AD severity. Outcomes were incident myocardial infarction, cerebrovascular accident (CVA), diabetes, hypertension, dyslipidemia, deep vein thrombosis (DVT), and pulmonary embolism. Cox regression analysis was used to compare outcomes in AD versus non-AD patients. Comparing 409,341 children with AD (93.2% mild, 5.5% moderate, and 1.3% severe) to 1,809,029 unaffected children, AD was associated with higher risk of DVT (hazard ratio [HR] 1.23; 95% confidence interval [95% CI] 1.02-1.48) and severe AD was associated with higher risk of CVA (HR 2.43; 95% CI 1.13-5.22) and diabetes (HR 1.46; 95% CI 1.06-2.01). Comparing 625,083 adults with AD (65.7% mild, 31.4% moderate, and 2.9% severe) to 2,678,888 unaffected adults, AD, especially when severe, was associated with higher risk of DVT (HR 1.14; 95% CI 1.11-1.18; and HR 1.64; 95% CI 1.49-1.82, respectively) and small but increased risks of CVA, diabetes, and dyslipidemia. Adults with severe AD had higher risk of myocardial infarction (HR 1.27; 95% CI 1.15-1.39), CVA (HR 1.21; 95% CI 1.13-1.30), diabetes (HR 1.15; 95% CI 1.09-1.22), dyslipidemia (HR 1.11; 95% CI 1.06-1.17), and pulmonary embolism (HR 1.39; 95% CI 1.21-1.60) compared with adults without AD. Atopic dermatitis, particularly when severe, is associated with small but increased risks of CV risk factors and events and significantly increased risk of venous thromboembolism.
