Risk Of Subsequent Cardiovascular Events Research Articles

Major bleeding increases the risk of subsequent cardiovascular events in patients with atrial fibrillation: insights from the SAKURA AF registry and RAFFINE registry.

Bleeding events are one of the major concerns in patients using oral anticoagulants (OACs). We aimed to evaluate the association between major bleeding and long-term clinical outcomes in atrial fibrillation (AF) patients taking OACs. We analyzed a database comprising two large-scale prospective registries of patients with documented AF: the RAFFINE and SAKURA registries. The primary outcome was major adverse cardiac and cerebrovascular events (MACCE), defined as the composite of all-cause death, ischemic stroke, and myocardial infarction. Major bleeding was defined in accordance with the criteria of the International Society on Thrombosis and Hemostasis. Cox multivariate analysis was used to determine the impact of major bleeding on the incidence of MACCE. The median follow-up period was 39.7 (interquartile range, 33.1-48.1) months. Among 6,633 patients with AF who were taking OAC, 298 (4.5%) had major bleeding and 737 (11.1%) had MACCE. The incidence of MACCE was higher in patients with bleeding than in those without (18.33 and 3.22, respectively, per 100 patient-years; log-rank p < 0.0001). Multivariate logistic regression analysis revealed older age, vitamin K antagonist use, and antiplatelet drug use as independent predictors of major bleeding. Median duration of MACCE occurrence after major bleeding was 41 (interquartile range, 3-300) days. Multivariate Cox hazard regression analysis showed that the risk of MACCE was significantly higher in patients with major bleeding compared to those without (hazard risk, 4.64; 95% confidence interval, 3.62-5.94; p < 0.0001). Major bleeding was associated with long-term adverse cardiovascular events among AF patients taking OAC. Therefore, reducing the risk of bleeding is important for improving clinical outcomes in patients with AF.

Chronic Obstructive Pulmonary Disease Exacerbations Increase the Risk of Subsequent Cardiovascular Events: A Longitudinal Analysis of the COPDGene Study.

Cardiovascular disease (CVD) is the most important comorbidity in patients with chronic obstructive pulmonary disease (COPD). COPD exacerbations not only contribute to COPD progression but may also elevate the risk of CVD. This study aimed to determine whether COPD exacerbations increase the risk of subsequent CVD events using up to 15 years of prospective longitudinal follow-up data from the COPDGene (Genetic Epidemiology of Chronic Obstructive Pulmonary Disease) study. The COPDGene study is a large, multicenter, longitudinal investigation of COPD, including subjects at enrollment aged 45 to 80 years with a minimum of 10 pack-years of smoking history. Cox proportional hazards models and Kaplan-Meier survival curves were used to assess the risk of a composite end point of CVD based on the COPD exacerbation rate. Frequent exacerbators exhibited a higher cumulative incidence of composite CVD end points than infrequent exacerbators, irrespective of the presence of CVD at baseline. After adjusting for covariates, frequent exacerbators still maintained higher hazard ratios (HRs) than the infrequent exacerbator group (without CVD: HR, 1.81 [95% CI, 1.47-2.22]; with CVD: HR, 1.92 [95% CI, 1.51-2.44]). This observation remained consistently significant in moderate to severe COPD subjects and the preserved ratio impaired spirometry population. In the mild COPD population, frequent exacerbators showed a trend toward more CVD events. COPD exacerbations are associated with an increased risk of subsequent cardiovascular events in subjects with and without preexisting CVD. Patients with COPD experiencing frequent exacerbations may necessitate careful monitoring and additional management for subsequent potential CVD.

The Effect of Age, Hypertension, and Overweight on Arterial Stiffness Assessed Using Carotid Wall Echo-Tracking in Childhood and Adolescence.

Arterial stiffness represents an independent predictor of the risk of subsequent cardiovascular events. Early identification of high-risk individuals is necessary for effective prevention and targeted interventions. Carotid wall echo-tracking is a modern method for an accurate evaluation of the structural and functional properties of carotid arteries. This study aimed to assess age and sex-specific reference values of the echo-tracking parameters of carotid stiffness in 400 healthy children and adolescents and to evaluate the potential early effect of elevated blood pressure and overweight in 69 overweight normotensives, 45 white coat hypertensives, and 44 essential hypertensives. Stiffness index β, pressure-strain elastic modulus (Ep), arterial compliance (AC), and pulse wave velocity β (PWV β) were evaluated using Aloka ProSound F75. Both white coat and essential hypertension were associated with impaired carotid wall properties with the greatest effect on Ep, followed by PWV β, index β, and AC. The excess weight showed a weaker effect on Ep and PWV β. This is the first study to compare the effects of white coat and essential hypertension on carotid arterial stiffness assessed using the echo-tracking technique in childhood and adolescence with direct application of pediatric reference values specific to age and sex.

Outcome after primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction complicated by cardiogenic shock

BackgroundPrimary percutaneous coronary intervention (PCI) for ST-segment-elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS) may reduce the risk of subsequent cardiovascular events but remains challenging. The study aim was to evaluate the clinical characteristics and long-term outcomes of patients undergoing primary PCI for STEMI with CS. MethodsWe conducted an observational cohort study of patients with STEMI who underwent primary PCI between April 2004 and December 2017 at Juntendo University Shizuoka Hospital. The primary outcome was cardiovascular death (CVD) during the median 3-year follow-up. We performed a landmark analysis for the incidence of CVD from 0 day to 1 year and from 1 to 10 years. ResultsAmong the 1758 STEMI patients in the cohort, 212 (12.1 %) patients with CS showed significantly higher 30-day CVD rate on admission than those without (26.4 % vs 2.9 %). Landmark Kaplan–Meier analysis showed that CVD from day 0 to year 1 was significantly higher in the patients with CS (log-rank p < 0.0001). Multivariate Cox regression analysis showed that CS was significantly associated with higher cardiovascular mortality (adjusted hazard ratio, 11.8; 95%confidence intervals, 7.78–18.1; p < 0.0001), but the mortality rates from 1 to 10 years were comparable (log-rank p = 0.68). ConclusionThe cardiovascular 1-year mortality rate for patients with STEMI was higher for those with CS on admission than without, but the mortality rates of >1 year were comparable. Surviving the early phase is essential for patients with STEMI and CS to improve long-term outcomes.

Variation in VEGFA and risk of cardiovascular disease in the UK Biobank

BackgroundCardiovascular disease (CVD) is an escalating global health crisis, contributing significantly to worldwide mortality and morbidity. Dyslipidemia stands as a critical risk factor for CVD. Vascular endothelial growth factor A (VEGFA) is pivotal in angiogenesis and represents a clinical target for CVD intervention. However, the impact of genetic modulation of VEGFA on lipid levels and the subsequent risk of cardiovascular events remains unclear.MethodsWe used LDpred2 to calculate genetic scores for lipid levels based on VEGFA variation, serving as instrumental variables to simulate the effect of VEGFA inhibitors. We then assessed the associations between genetic risk for lipid levels and CVD risk by conducting One-sample Mendelian randomization.ResultsOur results indicated that low-density lipoprotein cholesterol [LDL-C; odds ratio (OR) = 1.09, 95% CI: 1.06–1.11], remnant cholesterol (RC; OR = 1.24, 95% CI: 1.13–1.36), and triglycerides (TG; OR = 1.14, 95% CI: 1.07–1.22) were positively associated with the incidence of CVD. In contrast, high-density lipoprotein cholesterol (HDL-C) was inversely associated with the incidence of CVD (OR = 0.80, 95% CI: 0.76–0.86). When considering the genetic score for LDL-C constructed based on VEGFA, the group with a high genetic score demonstrated an elevated CVD risk (OR = 1.11, 95% CI: 1.04–1.19) compared to those with a low genetic score. Notably, One-sample Mendelian randomization results provided evidence of a causal relationship between LDL-C and CVD (p = 8.4×10−3) when using genetic variation in VEGFA as an instrumental variable.ConclusionsGenetic variation mimicking the effect of VEGFA inhibition, which lowers LDL-C levels, was causally associated with a reduced risk of cardiovascular events. These findings offer insight into the potential therapeutic relevance of modulating VEGFA-mediated lipid changes in the prevention and management of CVD.

Impact of heart failure severity and major bleeding events after percutaneous coronary intervention on subsequent major adverse cardiac events

Abstract Background Heart failure (HF) is one of high bleeding risk after percutaneous coronary intervention (PCI). Furthermore, major bleeding events increase the risk of subsequent cardiovascular events. However, it is unknown whether HF severity and bleeding events are associated with major adverse cardiac events (MACE). Purpose The aim of this study was investigating the impact of HF severity or bleeding events on subsequent MACE. Methods Clinical Deep Data Accumulation System (CLIDAS), a multicenter database with 7 tertiary medical hospitals, was developed to collect data directly for patient characteristics, medications, laboratory test, physiological test, cardiac catheterization and PCI treatment in electronic medical records. This retrospective analysis included 7,160 patients with PCI between April 2014 and March 2020 and have completed 3-year follow-up. The patients were divided into two groups: HF with high BNP (HF-hBNP) (&amp;gt;100 pg/ml) (n=384) and non-HF-hBNP (HF with low BNP and non-HF) (n=6,776). Furthermore, both groups were re-classified into two groups according to presence of major bleeding events in 30 days: HF-hBNP with 30-day bleeding (n=14), without 30-day bleeding (n=370), non-HF-hBNP with 30-day bleeding (n=74) and without 30-day bleeding (n=6,702). Primary endpoint was defined as MACE. Results HF with high BNP was an independent risk factor of MACE (hazard ratio [HR], 2.21; 95% confidence interval [CI], 1.64-2.98) compared with non-HF. Among the HF-hBNP patients, MACE incidence tended to be increased by 30-day bleeding (p=0.075). In addition, among the non-HF-hBNP patients, the bleeding events increased the risk of MACE (p=0.003). The multivariable Cox regression model revealed that other three groups were associated with a high risk compared with non-HF-hBNP without 30-day bleeding group: non-HF-hBNP with 30-day bleeding (HR, 3.90; 95% CI, 1.59-9.54), HF-hBNP without 30-day bleeding (HR, 2.19; 95% CI, 1.56-3.07) and HF-hBNP with 30-day bleeding (HR, 8.33; 95% CI, 2.57-27.0). Conclusion The real-world database CLIDAS revealed that HF with high BNP and major bleeding events in 30 days might be associated with MACE. Those results suggest that management of HF and prevention of bleeding complication in early days after PCI could be important to prevent MACE.

Abstract 13567: Comparison of Change in Lipoprotein(a) Mass and Molar Concentrations by Alirocumab and Risk of Subsequent Cardiovascular Events in ODYSSEY OUTCOMES

Background: Baseline (BL) lipoprotein(a) (Lp(a)) concentration is similarly related to cardiovascular (CV) risk when measured in either mass or molar units by immunoassay (IA). Because of Lp(a) isoform variation in mass, differences may exist between Lp(a) measurement methods in terms of relating change to risk reduction. We determined whether the reduction in major adverse cardiovascular events (MACE) by PCSK9 inhibitor alirocumab (ALI) had a similar relationship to the reduction in Lp(a) concentration as measured by 3 different methods. Methods: Lp(a) was measured by IA-mass (Siemens), IA-molar (Roche), and mass spectrometry (MS)-molar assays at BL and month 4 (M4) in a subgroup of patients in the ODYSSEY OUTCOMES trial which compared PCSK9 inhibitor ALI with placebo in patients with recent acute coronary syndrome. Changes in Lp(a) from BL to M4 were related to subsequent risk of MACE (coronary heart disease (CHD) death, nonfatal myocardial infarction (NFMI), fatal + nonfatal ischemic stroke, or unstable angina hospitalization) in the ALI group. Proportional hazards models were adjusted for BL Lp(a), BL LDL-C and its change from BL to M4, and other patient characteristics. Hazard ratios (HR) were calculated for the median change of each Lp(a) assay. All analyses were by intention-to-treat. Results: Among 5500 patients randomized to ALI with available data from all 3 Lp(a) assays, 443 experienced a subsequent MACE. Changes in Lp(a) IA-mass and MS-molar concentration were significantly related to reduced MACE risk, while change in IA-molar concentration was marginally significant; associations were more evident with CHD death + NFMI ( Figure ). MACE HRs for median change were similar across tests. Conclusion: With caveats of a modest number of MACE for analysis, moderately elevated Lp(a) levels, and intra-patient variability in serial values, 3 Lp(a) assay methods appeared similarly predictive of ALI MACE reduction.

Statin Treatment on Cardiovascular Risk After Retinal Artery Occlusion: A Historical Cohort Study

IntroductionRetinal artery occlusion (RAO) is a major cause of acute visual loss and patients with RAO have an increased risk for subsequent cardiovascular events. However, there is little evidence of whether the use of statins is associated with the prevention of cardiovascular events in patients with RAO. We investigated whether statin treatment in patients with RAO is associated with a lower risk of cardiovascular events.MethodsThis study was a historical cohort study with nested case–control analysis. Using the nationwide health insurance claims database in Korea, we retrospectively established a cohort of newly diagnosed RAO patients without prior cardiovascular events between January 2008 and March 2020. We defined the case group as those who had cardiovascular events (stroke or myocardial infarction) and the control group as RAO patients without primary outcome matched by sex, age, comorbidities, and duration of follow-up (1:2 incidence density sampling). Conditional logistic regression was performed.ResultsAmong 13,843 patients newly diagnosed with RAO, 1030 patients had cardiovascular events (mean follow-up period of 6.4 ± 3.7 years). A total of 957 cases were matched to 1914 controls. Throughout the study period, the proportion of patients taking statin was less than half. Statin treatment after RAO was associated with a low risk of cardiovascular events (adjusted OR, 0.637; 95% CI 0.520–0.780; P < 0.001). A longer duration of statin exposure was associated with a lower cardiovascular risk.ConclusionsIn patients with newly diagnosed RAO, treatment with statins, particularly long-term use, was associated with a low risk of future cardiovascular events.

Prognostic value of global myocardial flow reserve in patients with history of coronary artery bypass grafting.

It is not well understood whether positron emission tomography (PET)-derived myocardial flow reserve (MFR) is prognostic among patients with prior coronary artery bypass grafting (CABG). Consecutive patients with a clinical indication for PET were enrolled in the Houston Methodist DeBakey Heart and Vascular Center PET registry and followed prospectively for incident outcomes. The primary outcome was a composite of all-cause death, myocardial infarction (MI)/unplanned revascularization, and heart failure admissions. Cox proportional hazards models were used to study the association between MFR (<2 vs. ≥2) and incident events adjusting for clinical and myocardial perfusion imaging variables. The study population consisted of 836 patients with prior CABG; mean (SD) age 68 (10) years, 53% females, 79% Caucasian, 36% non-Hispanic, and 66% with MFR <2. Over a median (interquartile range [IQR]) follow-up time of 12 (4-24) months, there were 122 incident events (46 HF admissions, 28 all-cause deaths, 23 MI, 22 PCI/3 repeat CABG 90 days after imaging). In adjusted analyses, patients with impaired MFR had a higher risk of the primary outcome [hazard ratio (HR) 2.06; 95% CI 1.23-3.44]. Results were significant for admission for heart failure admissions (HR 2.92; 95% CI 1.11-7.67) but not for all-cause death (HR 2.01, 95% CI 0.85-4.79), or MI/UR (HR 1.93, 95% CI 0.92-4.05). Among patients with a history of CABG, PET-derived global MFR <2 may identify those with a high risk of subsequent cardiovascular events, especially heart failure, independent of cardiovascular risk factors and perfusion data.

Stroke in patients with heart failure and reduced or preserved ejection fraction.

Stroke is an important problem in patients with heart failure (HF), but the intersection between the two conditions is poorly studied across the range of ejection fraction. The prevalence of history of stroke and related outcomes were investigated in patients with HF. Individual patient meta-analysis of seven clinical trials enrolling patients with HF with reduced (HFrEF) and preserved ejection fraction (HFpEF). Of the 20 159 patients with HFrEF, 1683 (8.3%) had a history of stroke, and of the 13 252 patients with HFpEF, 1287 (9.7%) had a history of stroke. Regardless of ejection fraction, patients with a history of stroke had more vascular comorbidity and worse HF. Among those with HFrEF, the incidence of the composite of cardiovascular death, HF hospitalization, stroke, or myocardial infarction was 18.23 (16.81-19.77) per 100 person-years in those with prior stroke vs. 13.12 (12.77-13.48) in those without [hazard ratio 1.37 (1.26-1.49), P < 0.001]. The corresponding rates in patients with HFpEF were 14.16 (12.96-15.48) and 9.37 (9.06-9.70) [hazard ratio 1.49 (1.36-1.64), P < 0.001]. Each component of the composite was more frequent in patients with stroke history, and the risk of future stroke was doubled in patients with prior stroke. Among patients with prior stroke, 30% with concomitant atrial fibrillation were not anticoagulated, and 29% with arterial disease were not taking statins; 17% with HFrEF and 38% with HFpEF had uncontrolled systolic blood pressure (≥140 mmHg). Heart failure patients with a history of stroke are at high risk of subsequent cardiovascular events, and targeting underutilization of guideline-recommended treatments might be a way to improve outcomes in this high-risk population.

The relationship between neurological function trajectory, assessed by repeated NIHSS measurement, and long-term cardiovascular events, recurrent stroke, and mortality after ischemic stroke.

Clinically significant changes in neurological deficits frequently occur after stroke onset, reflecting further neurological injury or neurological improvement. However, the National Institutes of Health Stroke Scale (NIHSS) score is only evaluated once in most studies, usually at stroke onset. Utilizing repeated measures of NIHSS scores to identify different trajectories of neurological function may be more informative and provide more useful predictive information. We determined the association of neurological function trajectories with long-term clinical outcomes after ischemic stroke. A total of 4025 participants with ischemic stroke from the China Antihypertensive Trial in Acute Ischemic Stroke were included. Patients were recruited from 26 hospitals across China between August 2009 and May 2013. A group-based trajectory model was used to identify distinct neurological function trajectories, as measured by NIHSS at admission, 14 days or hospital discharge, and 3 months. Study outcomes were cardiovascular events, recurrent stroke, and all-cause mortality during 3-24 months after ischemic stroke onset. Cox proportional hazards models were used to examine the associations of neurological function trajectories with outcomes. We identified three distinct subgroups of NIHSS trajectories: persistent severe (persistent high NIHSS scores during the 3-month follow-up), moderate (NIHSS scores started at around 5 and gradually reduced), and mild (NIHSS scores always below 2). The three trajectory groups had different clinical profiles and different risk of stroke outcomes at 24-month follow-up. Compared to the mild trajectory group, patients in the persistent severe trajectory group had a higher risk of cardiovascular events (multivariable-adjusted hazard ratios (95% confidence intervals) = 1.77 (1.10-2.86)), recurrent stroke (1.82 (1.10-3.00)), and all-cause mortality (5.64 (3.37-9.43)). Those with moderate trajectory had an intermediate risk: 1.45 (1.03-2.04) for cardiovascular events and 1.52 (1.06-2.19) for recurrent stroke. Longitudinal neurological function trajectories derived from repeated NIHSS measurements during the first 3 months after stroke provide additional predictive information and are associated with long-term clinical outcomes. The trajectories characterized by persistent severe and moderate neurological impairment were associated with increased risk of subsequent cardiovascular events.

MICROVASCULAR ENDOTHELIUM FUNCTION RESPONSE TO N-3 POLYUNSATURATED FATTY ACIDS, VITAMIN E, SELENIUM AND LUTEIN ENRICHED FUNCTIONAL FOOD IN PATIENTS WITH CHRONIC CORONARY SYNDROME

Objective: Ischemic heart disease is the leading cause of death at a global level. A healthy lifestyle, and especially a healthy diet, can have the effect of reducing the risk of subsequent cardiovascular events and mortality. The aim of this study was to examine the effect of hen eggs enriched with n-3 polyunsaturated fatty acids (n-3 PUFAs), vitamin E, selenium and lutein consumption on oxidative stress level and microvascular endothelium function in patients with existing chronic coronary syndrome (CCS). Design and method: A total of 30 patients (9 women and 21 men) with existing CCS participated in this study. The participants were divided in two groups; Control group (N = 15) who ate three regular hen eggs per day (n-3 PUFAs 146 mg, vitamin E 0.595 mg, selenium 0.0183 mg, lutein 0.11mg/per egg), and Nutri4 group (N = 15) who ate three enriched hen eggs per day (n-3 PUFAs 432 mg, vitamin E 1.098 mg, selenium 0.0191 mg, lutein 0.616 mg/per egg) for three weeks. Peripheral microvascular reactivity in response to vascular occlusion (PORH), and iontophoresis of acetylcholine (AChID) and sodium nitroprusside (SNPID), as well as serum lipid and fatty acids profile, pro- and anti-inflammatory cytokines level, as well as biomarkers of oxidative stress and antioxidant capacity were measured before and after the respective diet protocol. Results: Consumption of Nutri4 eggs significantly decreased serum triglycerides levels and n6/n3 PUFAs ratio, decreased levels of cytokines IL-17A and TGF-1beta, and improved endothelium-dependent microvascular PORH and AChID, but not endothelium-independent response in patients with CCS. Consumption of both Nutri4 and regular hen eggs did not affect biomarkers of oxidative stress and antioxidant capacity in CCS patients. Conclusions: Consumption of hen eggs enriched with n-3 PUFAs, vitamin E, selenium and lutein for three weeks induced an anti-inflammatory response, a favorable effect on lipid and fatty acids profile, especially on triglycerides levels and n6/n3 PUFAs ratio, as well as an improved endothelium-dependent peripheral microvascular reactivity in patients with CCS.

Relationship of D-dimer Value to Mortality in Covid-19 Patients with Acute Coronary Syndrome at Haji Adam Malik Hospital Medan

Introduction: Coronaviruses (CoVs) are single-stranded positive-sense RNA viruses, which can trigger cardiovascular disease. Inflammation caused by SARS-CoV-2 can affect atherosclerotic plaques, induced prothrombotic changes in the blood and endothelium and caused their instability and myocardial infarction. Several prospective studies have demonstrated an association between increased baseline D-dimer levels and the risk of subsequent cardiovascular events. Several studied had showed the relationship of D-dimer value to mortality in COVID-19 patients with acute coronary syndrome at H. Adam Malik Hospital Medan. Method: This study was a descriptive analytic study using medical record data from central installation patients at H. Adam Malik Hospital in the period August 2020 to August 2021. The sample was calculated using the Lemeshow formula. Then the distribution test was carried out using Shapiro Wilk test. Inferential statistical analysis was performed to assess the relationship of D-dimer to mortality in COVID-19 patients with acute coronary syndrome at H. Adam Malik Hospital Medan using chi-square test. If chi-square criteria were not met, the inferential statistical analysis used was Fisher's exact or other alternative tests. The results were statistically significant if the p value &lt;0.05. Results: 70 subjects participated in the study and the average age of the research subjects was 58.2 years, majority were male. Most subjects experienced severe COVID-19; ECG found ST elevation and comorbid factors were mostly hypertension followed by hypertension and diabetes type 2. There was a relationship between D-dimer value and mortality in COVID-19 patients with acute coronary syndrome, with p value = 0.005. Conclusion: D-dimer values was associated with mortality in COVID-19 patients with acute coronary syndrome.

Undiagnosed obstructive sleep apnea increases risk of hospitalization among a racially diverse group of older adults with comorbid cardiovascular disease.

Undiagnosed obstructive sleep apnea (OSA) is associated with increased risk for subsequent cardiovascular events, hospitalizations, and mortality. The primary objective of this study was to determine the association between undiagnosed OSA and subsequent hospitalizations among older adults with preexisting cardiovascular disease (CVD). A secondary objective was to determine the risk of 30-day hospital readmission associated with undiagnosed OSA among older adults with CVD. This was a retrospective cohort study of a 5% sample of Medicare administrative claims data for years 2006-2013. Beneficiaries aged 65 years and older diagnosed with CVD were included. Undiagnosed OSA was defined as the 12-month period prior to OSA diagnosis. A similar 12-month period among beneficiaries not diagnosed with OSA was used for the comparison group (no OSA). Our primary outcome was the first all-cause hospital admission. Among beneficiaries with a hospital admission, 30-day readmission was assessed for the first hospital admission only. Among 142,893 beneficiaries diagnosed with CVD, 19,390 had undiagnosed OSA. Among beneficiaries with undiagnosed OSA, 9,047 (46.7%) experienced at least 1 hospitalization whereas 27,027 (21.9%) of those without OSA experienced at least 1 hospitalization. Following adjustment, undiagnosed OSA was associated with increased risk of hospitalization (odds ratio 1.82; 95% confidence interval 1.77, 1.87) relative to no OSA. Among beneficiaries with ≥ 1 hospitalization, undiagnosed OSA was associated with a smaller but significant effect in weighted models (odds ratio 1.18; 95% confidence interval 1.09, 1.27). Undiagnosed OSA was associated with significantly increased risk of hospitalization and 30-day readmissions among older adults with preexisting CVD.

The interaction of persistent antiphospholipid antibodies positivity and cigarette smoking is associated with an increased risk of cardiovascular events: Cross-sectional and longitudinal analysis

BackgroundThe antiphospholipid antibody (aPL)-positivity was suggested as a nontraditional risk of coronary artery disease (CAD) and it was associated with cigarette smoking. The co-occurrence of them was usually reported in individuals with cardiovascular diseases. This study was to demonstrate their interaction on the increasing risk of cardiovascular events. Methods and resultsA total of 826 consecutive male individuals who underwent coronary angiography (CAG) /percutaneous coronary intervention (PCI) were prospectively followed and classified into three groups based on different smoking statuses. The current smoking subjects had the highest occurrence of aPL-positivity, including aCL IgM (20.1%) and aβ2GP1 IgM (15.5%). IgM isotype positivity was an independent risk factor of CAD in the multivariate model, OR: 2.70 (1.52–4.80) for aCL IgM and OR:2.50 (1.35–4.63) for aβ2GP1 IgM.The interaction of current smoking and IgM isotype positivity was significantly associated with increased risk of CAD, OR: 8.75(4.59–16.66) for aCL IgM and OR: 8.78(4.28–17.98) for aβ2GP1 IgM. During about 3 years of follow-up, the smoking patients carrying persistent aPL positivity had the highest cumulative incidence of recurrent myocardial infarction and in-stent restenosis after CAD. ConclusionThe interaction of current smoking and IgM isotype positivity was significantly associated with the increased risk of CAD, including positive aCL IgM and aβ2GP1 IgM. Cigarette smoking elevated the risk of subsequent cardiovascular events in the presence of IgM isotype positivity, including recurrent myocardial infarction and in-stent restenosis.

Abstract 13962: Anemia Correction Improves Mortality and Other Outcomes in Patients With Incident Atrial Fibrillation: A Nationwide Cohort Study

Background: Emerging evidence has suggested that anemia in patients with atrial fibrillation (AF) may lead to poor outcomes. We investigated the association of anemia after AF diagnosis with mortality and cardiovascular (CV) events. Methods: Using the database of Korean National Health Insurance Service and health examination, a total of 102,801 patients newly diagnosed with AF (2005-2015) were categorized into four groups according to the status of anemia before and after AF diagnosis. The primary outcomes were all-cause mortality and composite of CV death, ischemic stroke, heart failure hospitalization, or acute myocardial infarction. Results: The median follow-up duration was 5.3 years. Among AF patients with anticoagulation, the non-anemia to anemia and consistent anemia groups were associated with a higher risk of mortality (hazard ratio [95% CI]: 1.56 [1.34-1.80] and 1.59 [1.30-1.95]) and CV composite outcome (1.30 [1.15-1.47] and 1.28 [1.09-1.51]) compared to the consistent non-anemia group, respectively. Correction of anemia after diagnosis of AF (anemia to non-anemia group, HR [95%CI]: 1.38 [1.13-1.69]) showed a lower risk of mortality compared to the patients with persistent uncorrected anemia (consistent anemia group, 1.59 [1.30-1.95]). These results were consistently observed in AF patients without anticoagulation. Conclusions: Anemia was associated with an increased risk of mortality and CV outcomes in patients with newly diagnosed AF. Anemia correction after AF diagnosis could reduce the risk of subsequent CV events and mortality. Correction of anemia should be encouraged as part of a comprehensive approach to AF management to improve outcomes.

European Physician Survey Characterizing the Clinical Pathway and Treatment Patterns of Patients Post-Myocardial Infarction.

The 2019 European Society of Cardiology and European Atherosclerosis Society (2019 ESC/EAS) guidelines stress the importance of managing low-density lipoprotein cholesterol (LDL-C) after myocardial infarction (MI) to reduce the risk of cardiovascular events. Information on guideline implementation is limited. The aim of this survey was to describe current clinical practice regarding LDL-C management in the first year post-MI across Europe, improving understanding of the role of ESC/EAS guidelines on clinical practice. A qualitative web-based cross-sectional physician survey about the patient pathway and LDL-C management post-MI was conducted in 360 physicians from France, Italy, Germany, The Netherlands, Spain, and the UK (n = 60/country) between December 2019 and June 2020. Secondary and primary care physicians (SCPs/PCPs) described their experiences treating patients post-MI over the preceding 2months. Physicians reported that on average 90.7% of patients not prescribed lipid-lowering therapy (LLT) before an MI initiated LLT as inpatients; for patients already taking LLT, treatment was intensified for 64.7% of inpatients post-MI. SCPs reported prescribing higher-intensity statins and/or ezetimibe for between 72.3% (Italy) and 88.6% (UK) of patients post-MI. More than 80.0% of SCPs and 51.2% of PCPs stated that they would initiate a change in LLT immediately if patients did not achieve their LDL-C treatment goal by 12weeks post-MI; 82.0% of SCPs and 55.1% of PCPs reported referring to 2019 ESC/EAS guidelines for management of patients post-MI. Barriers to initiating PCSK9 inhibitors (PCSK9is) included prior prescription of a maximally tolerated dose of statin (49.4%) and/or ezetimibe (38.9%), requirement to reach threshold LDL-C levels (44.9%), and pre-authorization requirements (30.4%). Differences in clinical practice post-MI were reported across the countries surveyed, including divergence between 2019 ESC/EAS and local guidelines. Increased use of innovative medicines to achieve LDL-C goals should reduce risk of subsequent cardiovascular events in very high-risk patients post-MI.

Association of Serial High-Sensitivity Cardiac Troponin T With Subsequent Cardiovascular Events in Patients Stabilized After Acute Coronary Syndrome

Studies have demonstrated an association between single measures of high-sensitivity troponin (hsTn) and future cardiovascular events in patients with chronic coronary syndromes. However, limited data exist regarding the association between changes in serial values of hsTn and subsequent cardiovascular events in this patient population. To evaluate the association between changes in high-sensitivity troponin T (hsTnT) and subsequent cardiovascular events in patients stabilized after acute coronary syndrome (ACS). This is a secondary analysis from the Improved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVE-IT), a randomized clinical trial of ezetimibe vs placebo on a background of simvastatin in 18 144 patients hospitalized for an ACS across 1147 sites in 39 countries. The current biomarker substudy includes the 6035 participants consenting to the biomarker substudy with available hsTnT at months 1 and 4. Data were collected from October 26, 2005, through July 8, 2010, with the database locked October 21, 2014. Data were analyzed from February 28, 2021, through August 14, 2022. The outcomes of interest were cardiovascular death, myocardial infarction (MI), stroke, or hospitalization for heart failure (HHF). Associations of absolute and relative changes in hsTnT between month 1 and month 4 as a function of the starting month 1 hsTnT and the composite outcome were examined using landmark analyses. Of 6035 patients in this analysis (median [IQR] age, 64 [57-71]), 1486 (24.6%) were female; 361 (6.0%) were Asian; 121 were (2.0%) Black; 252 (4.2%) were Spanish descent; 4959 were (82.2%) White; and 342 (5.7%) reported another race (consolidated owing to small numbers), declined to respond, or were not asked to report race owing to regulatory prohibitions. Most patients (4114 [68.2%]) had stable hsTnT values (change <3 ng/L), with 1158 (19.2%) and 763 (12.6%) having changes of 3 to less than 7 ng/L and 7 ng/L or more, respectively. After adjustment for clinical risk factors and stratification by the starting month 1 hsTnT level, an absolute increase in hsTnT of 7 ng/L or more was associated with a more than 3-fold greater risk of the composite outcome (adjusted hazard ratio [aHR], 3.33; 95% CI, 1.99-5.57; P < .001), whereas decreases of 7 ng/L or more were associated with similar to lower risk (aHR, 0.51; 95% CI, 0.26-1.03; P = .06) compared with stable values. There was a stepwise association moving from larger absolute decreases (aHR, 0.51; 95% CI, 0.26-1.03) to larger absolute increases (aHR, 3.33; 95% CI, 1.99-5.57) in hsTnT with future risk of the composite outcome (P trend <.001). A similar association was observed when analyzed on the basis of relative percent and continuous change. Among stable patients post-ACS, changes in hsTnT were associated with a gradient of risk of subsequent cardiovascular events across the range of starting hsTnT values. Serial assessment of hsTnT may refine risk stratification with the potential to guide therapy decisions in this patient population. ClinicalTrials.gov Identifier: NCT00202878.

Comparison of Risk of Serious Cardiovascular Events after Hemorrhagic versus Ischemic Stroke: A Population-Based Study

Patients with ischemic stroke are considered a very high risk population for subsequent cardiovascular events and guidelines recommend intensive preventive strategies. However, there is no clear recommendation that patients with hemorrhagic stroke should also be regarded as a very high cardiovascular risk population. To compare the risk of subsequent cardiovascular morbidity/mortality between patients with incident hemorrhagic and ischemic stroke. Patients aged ≥18 years with incident hemorrhagic or ischemic stroke between 1998 and 2017 and no prior history of serious vascular event were identified from UK Clinical Practice Research Datalink (CPRD GOLD) linked to Hospital Episode Statistics data. The cohort included 32,091 patients with an overall follow-up of 381,237 person-years (median: 11.8 years). After adjusting for potential confounders, patients with incident hemorrhagic stroke had no significantly different risk of subsequent cardiovascular morbidity compared with patients with incident ischemic stroke-coronary heart disease (CHD; hazard ratio [HR]: 0.86, 95% confidence interval [CI]: 0.56-1.32), recurrent stroke (HR: 0.92, 95% CI: 0.83-1.02), peripheral vascular disease (PVD; HR: 1.15, 95% CI:0.56-2.38), or heart failure (HR: 1.03, 95% CI: 0.61-1.74). Patients with incident hemorrhagic stroke had significantly higher risk of subsequent cardiovascular disease (CVD)-related mortality (HR: 2.35, 95% CI: 2.04-2.72) and all-cause mortality (HR: 2.16, 95% CI: 1.94-2.41). Propensity-score matched analysis of 1,039 patients with hemorrhagic stroke and 1,039 with ischemic stroke showed similar risk in subsequent cardiovascular morbidity-CHD (stratified HR [sHR]: 0.92, 95% CI: 0.55-1.54), recurrent stroke (sHR: 0.93, 95% CI: 0.82-1.02), PVD (sHR: 1.04 95% CI: 0.45-2.41), or heart failure (sHR: 0.71, 95% CI: 0.39-1.27). The risk of subsequent cardiovascular events is similar between patients with incident hemorrhagic and ischemic stroke. Patients with previous hemorrhagic stroke should be regarded as a population at very high risk for subsequent CVD.

Coronavirus Disease 2019 Severity and Risk of Subsequent Cardiovascular Events.

Little is known about the relationship between coronavirus disease 2019 (COVID-19) severity and subsequent risk of experiencing a cardiovascular event (CVE) after COVID-19 recovery. We evaluated this relationship in a large cohort of United States adults. Using a claims database, we performed a retrospective cohort study of adults diagnosed with COVID-19 between 1 April 2020 and 31 May 2021. We evaluated the association between COVID-19 severity and risk of CVE >30 days after COVID-19 diagnosis using inverse probability of treatment-weighted competing risks regression. Severity was based on level of care required for COVID-19 treatment: intensive care unit (ICU) admission, non-ICU hospitalization, or outpatient care only. A total of 1 357 518 COVID-19 patients were included (2% ICU, 3% non-ICU hospitalization, and 95% outpatient only). Compared to outpatients, there was an increased risk of any CVE for patients requiring ICU admission (adjusted hazard ratio [aHR], 1.80 [95% confidence interval {CI}, 1.71-1.89]) or non-ICU hospitalization (aHR, 1.28 [95% CI, 1.24-1.33]). Risk of subsequent hospitalization for CVE was even higher (aHRs, 3.47 [95% CI, 3.20-3.76] for ICU and 1.96 [95% CI, 1.85-2.09] for non-ICU hospitalized vs outpatient only). COVID-19 patients hospitalized or requiring critical care had a significantly higher risk of experiencing and being hospitalized for post-COVID-19 CVE than patients with milder COVID-19 who were managed solely in the outpatient setting, even after adjusting for differences between these groups. These findings underscore the continued importance of preventing severe acute respiratory syndrome coronavirus 2 infection from progressing to severe illness to reduce potential long-term cardiovascular complications.
