Abstract 16478: Effect of Sodium Glucose Cotransporter 2 Inhibitors on Major Adverse Cardiovascular Events in Cancer Patients Treated With Immune Checkpoint Inhibitors

Introduction: The cardiac adverse events (irAEs) secondary to immune checkpoint inhibitors (ICI) are associated with a high rate of morbidity and mortality. There are no data on the effect of concomitant sodium glucose cotransporter 2 inhibitors (SGLT2i) on the rates of major adverse cardiovascular events (MACE) among patients treated with an ICI. Hypothesis: Whether, the use of SGLT2i among ICI-treated patients may reduce MACE. Methods: This was a population-based cohort study between 2014 and 2023 including cancer patients treated with ICI aged over 18 years across the United States. SGLT2i use while on an ICI was defined as the initiation of SGLT2i therapy after the first record of ICI treatment among patients currently undergoing ICI therapy. The risk of incident MACE in patients on an ICI who were also prescribed an SGLT2i therapy was compared with 1:1 propensity score-matched patients on ICI who were never prescribed an SGLT2i. Hazard ratios (HRs) and 95% confidence intervals (CIs) for MACE were estimated using Cox proportional hazards regression. MACE was defined as a composite of myocardial infarction, heart failure (HF), and ischemic stroke. Results: There were 216 cancer patients undergoing ICI therapy who were newly treated with SGLT2i. These were compared to 216 controls. Over a mean follow-up period of six years, there were 107 MACE events. There were 44 events (20.4%) among those on an SGLT2i and 63 among controls (HR=0.61, 95% CI: 0.41-0.90; log-rank test p=0.011). Of the individual components of MACE, rates of HF were lower where there were 22 HF events (20.4%) among those on an SGLT2i and 37 among controls (HR=0.51, 95% CI: 0.30-0.86; log-rank test p=0.010). There were no differences in the rates of stroke (HR: 0.55, 95% CI: 0.29-1.04) and myocardial infarction (HR: 0.97, 95% CI: 0.38-2.43). Conclusions: In an observational, retrospective study, SGLT2i therapy was associated with a reduced risk for cardiac events compared to those who never treated with SGLT2i. These findings underscore the potential therapeutic value of SGLT2i in the prevention of MACE in cancer patients receiving immunotherapy and warrant further research.

The Prognostic Value of Arterial Stiffness According to Socioeconomic Status.

Individuals of low socioeconomic status (SES) often exhibit increased cardiovascular risk factors and a worse prognosis. We conducted this study to ascertain whether brachial-ankle pulse wave velocity (baPWV), a straightforward and reliable measure of arterial stiffness, can hold prognostic value for people with low SES. We retrospectively analyzed a total of 1266 subjects (mean age 64.6 ± 11.6 years; 47.2% female) without documented cardiovascular disease who had undergone baPWV measurement. The subjects included 633 National Health Insurance Beneficiaries (NHIB) and 633 Medical Aid Beneficiaries (MAB), matched for major clinical features through a 1:1 propensity score matching method. Major adverse cardiovascular events (MACE), such as death, non-fatal myocardial infarction, non-fatal ischemic stroke, coronary revascularization, and heart failure necessitating admission, were assessed during the clinical follow-up. During a median follow-up period of 4.2 years (interquartile range, 2.2-5.7 years), there were 77 MACE cases (6.1%). In multivariable Cox regression analyses, baPWV was identified as a significant predictor of MACE in both groups, regardless of the use of three different baPWV criteria (median value, Asian consensus recommendation, and cut-off value obtained by receiver operating characteristic [ROC] curve analysis). In both groups, the baPWV value obtained using ROC curve analysis emerged as the best predictor of MACE. This predictive value was stronger in the NHIB group (hazard ratio, 5.80; 95% confidence interval, 2.30-14.65; p < 0.001) than in the MAB group (hazard ratio, 3.30; 95% confidence interval, 1.57-6.92; p = 0.002). baPWV was associated with future MACE incidence in both NHIB and MAB groups. Since baPWV is simple and cost-effective to measure, it could be efficiently used as a risk stratification tool for individuals with low SES.

Incidental Cardiovascular Abnormalities in the Abdominal Aortic Aneurysm (AAA) Surveillance Population During the AAA Get Fit Trial: A Case Series and Review of the Literature.

Background The prevalence of cardiovascular disease and incidence of major adverse cardiovascular events (MACEs) is very high among the abdominal aortic aneurysm (AAA) surveillance population. Formal assessments of and interventions to reduce cardiovascular risk are not a routine part of the surveillance programme at present. However, its potential importance is highlighted by incidental findings during the AAA Get Fit Trial, a randomised controlled trial which included baseline cardiopulmonary exercise testing (CPET). We speculate that CPET can act as an opportunistic screening programme to identify cardiovascular disease in AAA surveillance patients. Methods The AAA Get Fit Trial was a prospective, randomised controlled trial at a tertiary vascular centre, Manchester University NHS Foundation Trust, conducted between November 2017 and August 2019. Patients underwent CPET at baseline, 8, 16, 24 and 36 weeks as well as clinical history and examination and blood tests. We report on incidental cardiovascular abnormalities diagnosed during the trial. Results Of the 59 participants in the trial, four (6.8%) were identified to have abnormal findings suggestive of unstable cardiovascular disease. On subsequent further investigation, two patients were diagnosed and treated for severe coronary artery disease after abnormal ECG findings were noted during CPET. One patient was diagnosed with unstable angina after obtaining a detailed history on baseline assessment which was treated medically before going on to have a successful elective AAA repair. Conclusions There is a high incidence of MACEs among this high-risk population both pre and perioperatively. Identifying and treating cardiovascular disease among the AAA surveillance population must be a focus of the future AAA screening programme.

Chronic Kidney Disease Predicts Adverse Major Cardiovascular Events and Adverse Limb Events in Patients With Diabetes and Peripheral Arterial Disease.

This study aims to explore the effect in each stage of chronic kidney disease (CKD) on the major adverse cardiovascular events (MACE) in diabetes mellitus (DM) patients with peripheral arterial disease (PAD). A total of 246 DM patients with diagnosed PAD were enrolled in this study. Of these, 86 patients (35%) died and 34 patients had non-fatal cardiovascular events occurred at the last 7 years follow-up. The baseline eGFR obtained from the first quantified eGFR value within 6 months from the date of enrollment estimated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI). Then, based on eGFR at entry, we defined CKD as an eGFR < 60 mL/min/1.73 m2, and stratified all patients into four groups: eGFR-1, normal eGFR (≥90 mL/min/1.73 m2); eGFR-2, mildly decreased eGFR (60-89 mL/min/1.73 m2); eGFR-3, moderately decreased eGFR (30-59 mL/min/1.73 m2); and eGFR-4, severely decreased eGFR (<30 mL/min/1.73 m2). The mean eGFR was 54.4 ± 28.9 mL/min/1.73m2, and more than 30% of all patients had CKD (eGFR <60 mL/min/1.73m2). The seven-year cumulative incidence of MACE was 29.8% (95% confident interval [95% CI] 15.5-35.7) for eGFR-1 group, 40.4% (95% CI 27.4-45.2) for eGFR-2group, 66.2% (95% CI 47.6-71.4) for eGFR-3 group, and 94% (95% CI 75.0-99.0) for eGFR-4 group. In addition, after adjustment, hazard ratio (HR) for MACE was 2.36 (95% CI 1.26-4.40) in the eGFR-3 group and 7.62 (95% CI 3.71-15.66) in the eGFR-4 group. Restricted mean survival time (RMST) for survival analysis was consistent with HR in this study. After adjusting confounders, relative to eGFR-1 group, an association between the eGFR group and MACE outcome was found only in eGFR-3 group and eGFR-4 group. The moderate to severe reduction in eGFR, was an independent risk factor for MACE among DM patients with PAD throughout a 7-year follow-up duration. Thus, early CKD screening might be essential in the management of diabetic patients with PAD.

Impact of Persistent Medication Adherence and Compliance with Lifestyle Recommendations on Major Cardiovascular Events and One-Year Mortality in Patients with Type 2 Diabetes and Advanced Stages of Atherosclerosis: Results From a Prospective Cohort Study.

The aim of this study was to evaluate the impact of single and combined effects of persistent medication adherence and compliance with lifestyle recommendations on the incidence of major adverse cardiovascular events (MACE) and one-year all-cause mortality in patients with type 2 diabetes (T2D) and peripheral artery disease (PAD) after partial foot amputation (PFA), representing a unique cohort of patients with advanced stages of atherosclerosis. This is a prospective cohort study of 785 consecutive patients (mean age 60.9 ± 9.1 years; 64.1% males). Medication adherence was evaluated by using the proportion of days covered (PDC) measure calculation and was defined as a PDC ≥80%. It derived as an average of PDCs of the following four classes of drugs: a) antidiabetics (oral hypoglycemic medications and/or insulin); b) ACEI or ARBs; c) Statins; d) antiplatelet drugs. Lifestyle compliance was defined as a PDC ≥80% comprising of PDCs of a) physical activity of ≥30 minutes per day; b) healthy nutrition and weight management; c) non-smoking. Cox proportional hazard models adjusted for confounders were used. Total all-cause mortality was 16.9% (n = 133) at one-year follow-up. After adjusting for confounders, compared to adherent/compliant patients (n = 432), non-adherent and/or non-compliant patients had an increased risk of one-year mortality: HR = 8.67 (95% CI [5.29, 14.86] in non-adherent/non-compliant patients (n = 184), p < 0.001; HR = 3.81 (95% CI [2.03, 7.12], p < 0.001) in adherent/non-compliant patients (n = 101) and HR = 3.14 (95% CI [1.52, 6.45] p = 0.002) in non-adherent/compliant patients (n = 184). The incidence of MACE followed similar pattern (HR = 9.66 (95% CI [6.55, 14.25] for non-adherence/non-compliance; HR = 3.48 (95% CI [2.09, 5.77] and HR = 3.35 (95% CI [1.89, 5.91], p < 0.001 for single adherence or compliance. Medication adherence and compliance to lifestyle recommendations have shown to be equally effective to reduce the incidence of MACE and one-year mortality in patients with diabetes and PAD after PFA representing a population with highly advanced stages of atherosclerotic disease. Our findings underline the necessity to give lifestyle intervention programs a high priority and that costs for secondary prevention medications should be covered for patients under these circumstances. This study analyzed the single and combined effects of medication adherence and compliance with lifestyle recommendations on cardiovascular events and mortality in patients with type 2 diabetes and advances stages of atherosclerosis over a period of one year.Evaluation of medication adherence included antidiabetics, statins, dual antiplatelets and ACEI/ARBs, whereas lifestyle recommendations included healthy nutrition, physical activity and smoking cessation.Persistent medication adherence and lifestyle changes have shown to be equally effective to reduce the incidence of MACE and one-year mortality in patients representing a population with highly advanced stages of atherosclerotic disease, and positive effects added up to a double effect if patients were persistently adherent and compliant with both interventions.

Effectiveness of lipid-lowering therapy on mortality and major adverse cardiovascular event outcomes in patients undergoing percutaneous coronary intervention: a network meta-analysis of randomised controlled trials

LncRNA TPRG1-AS1 Screened the Onset of Acute Coronary Syndromes and Predicted Severity and the Occurrence of MACE During Patients' Hospitalization.

Acute coronary syndrome (ACS) is a common acute myocardial ischemia syndrome and is one of the death-related causes of cardiovascular diseases. Identifying biomarkers to indicate disease severity and predict the occurrence of major adverse cardiovascular events (MACE) would benefit the clinical prognosis of ACS. This study estimated the expression and significance of lncRNA TPRG1-AS1 in the onset and development of ACS, aiming to explore a novel biomarker for the diagnosis and prognosis of ACS. A total of 109 ACS patients and 66 patients who received coronary angiography and excluded ACS were enrolled in this study. TPRG1-AS1 in the serum of study subjects was analyzed by PCR. The significance of TPRG1-AS1 in screening ACS was evaluated by ROC analysis. The association of TPRG1-AS1 with the disease severity of ACS was assessed by Pearson correlation analysis with patients' clinicopathological features. The potential of TPRG1-AS1 in predicting the occurrence of MACE was assessed by logistic regression analysis. Significant upregulation of TPRG1-AS1 was observed in ACS patients, which served as a risk factor for ACS and distinguish between ACS patients and the normal group. TPRG1-AS1 was positively correlated with Gensini score, cys-C, cTnI, and NT-proBNP levels of ACS patients, which indicate severe development of ACS. Additionally, increasing serum TPRG1-AS1 was associated with the high incidence of MACE during patients' hospitalization and was identified as a risk factor for MACE in ACS patients. Upregulated TPRG1-AS1 in ACS served as a diagnostic biomarker and predicted the severe development of patients.

Sex Differences in Cardiovascular Outcomes and Cholesterol-Lowering Efficacy of PCSK9 Inhibitors: Systematic Review and Meta-Analysis

BackgroundGuideline-recommended low-density lipoprotein cholesterol (LDL-C) thresholds are often not achieved in women. The proprotein convertase subtilisin/kexin type-9 inhibitor (PCSK9i) monoclonal antibodies can help further reduce LDL-C and major adverse cardiovascular events (MACE) although differences in efficacy by sex and type are less understood. ObjectivesThe authors sought to determine if there are differences in the efficacy of LDL-C lowering and reduction in the risk of MACE by sex and type of PCSK9i. MethodsA comprehensive literature search was done through October 17, 2022, for published trials comparing PCSK9i vs control. Outcomes assessed were LDL-C reduction and incidence of MACE following the use of PCSK9i vs placebo, stratified by sex and type of PCSK9i used. ResultsWe identified 16 trials with 54,996 adults, and 15,143 (27.5%) of them were female. PCSK9i significantly reduced MACE compared to placebo in both women (HR: 0.86, 95% CI: 0.74-0.97, P < 0.001) and men (HR: 0.85, 95% CI: 0.79-0.91, P < 0.001) with no significant sex difference (MD −0.01, 95% CI: −0.14 to −0.13, P = 0.930). PCSK9i also significantly reduced LDL-C levels in both sexes at 12 weeks (females: MD −62.57, 95% CI: −70.24 to −54.91, P < 0.001; males: MD −66.19, 95% CI: −72.03 to −60.34, P < 0.001) and 24 weeks (females: MD −47.52, 95% CI: −52.94 to −42.09, P < 0.001; males: MD −54.07, 95% CI: −59.46 to −48.68, P < 0.001). Significant sex difference was seen in the LDL reduction of PCSK9i for both 12 weeks (males vs females: MD −4.55, 95% CI: −7.34 to −1.75, P < 0.01) and 24 weeks (males vs females: MD −7.11, 95% CI: −9.99 to −4.23, P < 0.001). ConclusionsThe use of PCSK9i results in significant LDL-C and MACE reduction in both males and females. While there is no significant sex difference in MACE reduction, LDL-C reduction is greater in males than in females. Our data support the equal use of PCSK9i in all eligible patients, regardless of sex.

Safety-Net Hospital Status Is Associated With Coronary Artery Bypass Grafting Outcomes at an Urban Academic Medical Center

IntroductionSocioeconomic disparities impact outcomes after cardiac surgery. At our institution, cardiac surgery cases from the safety-net, county funded hospital (CH), which primarily provides care for underserved patients, are performed at the affiliated university hospital. We aimed to investigate the association of socioeconomic factors and CH referral status with outcomes after coronary artery bypass grafting (CABG). MethodsThe institutional Adult Cardiac Surgery database was queried for perioperative and demographic data from patients who underwent isolated CABG between January 2014 and June 2020. The primary outcome was major adverse cardiovascular event (MACE), a composite of postoperative myocardial infarction, stroke, or death. Secondary outcomes included individual complications. Chi-square, Wilcoxon rank-sum, and logistic regression analyses were used to compare differences between CH and non-CH cohorts. ResultsWe included 836 patients with 472 (56.5%) from CH. Compared to the non-CH cohort, CH patients were younger, more likely to be Hispanic, non-English speaking, and be completely uninsured or require state-specific financial assistance. CH patients were more likely to have a history of tobacco and drug use, liver disease, diabetes, prior myocardial infarction, and greater degrees of left main coronary and left anterior descending artery stenosis. CH cases were less likely to be elective. The incidence of MACE was significantly higher in the CH cohort (16.3% versus 8.2%, P = 0.001). There were no significant differences in 30-d mortality, home discharge, prolonged mechanical ventilation, bleeding, sepsis, pneumonia, new dialysis requirement, cardiac arrest, or multiorgan system failure between cohorts. CH patients were more likely to develop renal failure and less likely to develop atrial fibrillation. On multivariable analysis, CH status (odds ratio 2.39, 95% confidence interval 1.25-4.55, P = 0.008) was independently associated with MACE. ConclusionsCH patients undergoing CABG presented with greater comorbidity burden, more frequently required nonelective surgery, and are at significantly higher risk of postoperative MACE.

Association of serum uric acid with prognosis in patients with myocardial infarction: an update systematic review and meta-analysis

BackgroundThe prognostic significance of serum uric acid (SUA) in individuals who have experienced myocardial infarction (MI) remains a subject of academic debate. Thus, the aim of this study was to examine the occurrence of immediate and long-term adverse outcomes in individuals with elevated levels of uric acid (UA) following a diagnosis of MI.MethodThis study conducted a literature search from PubMed, Embase, Web of Science, Medline, Cochrane Library, Emcrae, and Scopus to perform a systematic review and meta-analysis of the prognostic impact of MI with a hyper SUA to assess short-term (30-day or in-hospital) and long-term mortality, the incidence of major adverse cardiovascular events (MACE), and its adverse event rate in relation to SUA. The literature search was conducted up until April 2023. A random effects model and risk ratio (RR) were used as epidemiological indicators. For indicators with low disease rates, treatment intensity was reduced and RR was considered equivalent to odds ratio (OR). Hazard Ratio (HR), RR, and OR extracted from the data were simultaneously subjected to multivariable adjustment for confounding factors. In addition, P values for all original hypotheses were extracted and a meta-analysis was conducted. High SUA was defined as SUA levels equal to or greater than 420 μmol/L (7.0 mg/dL) for males and equal to or greater than 357 μmol/L (6.0 mg/dL) for females. The quality of the literature was evaluated using the Newcastle–Ottawa Scale (NOS).ResultsThis comprehensive study included a total of 41 investigations, involving a large sample size of 225,600 individuals who had experienced MI. The findings from the meta-analysis reveal that patients diagnosed with hyperuricemia have significantly increased rates of short-term mortality (RR = 2.14, 95% CI = 1.86, 2.48) and short-term incidence of MACE (RR = 1.94, 95% CI = 1.65–2.11). Furthermore, long-term adverse outcomes, including all-cause mortality (RR = 1.46, 95% CI = 1.40–1.51) and incidence of MACE (RR = 1.43, 95% CI = 1.35–1.52), were also found to be higher in this specific patient population.ConclusionPatients diagnosed with MI and elevated SUA levels exhibit a heightened incidence of MACE during their hospital stay. Furthermore, these individuals also experience elevated rates of in-hospital mortality and mortality within one year of hospitalization. However, it is important to note that further randomized controlled trials are necessary to validate and authenticate these findings.

Possible effect of the early administration of tranexamic acid on myocardial injury in patients with severe trauma

Hemodynamic stabilization plays a crucial role in the treatment of patients suffering from severe trauma. Current guidelines recommend the early administration of tranexamic acid (TXA) for bleeding control. While less blood loss can result in less end-organ damage, including myocardial injury, TXA also exhibits prothrombotic effects with potentially adverse myocardial effects. The aim of this study was to investigate the association between the administration of TXA and myocardial injury in patients with severe trauma. We conducted a monocentric cohort study including severely injured patients ≥ 18 years [defined by Injury severity score (ISS) ≥ 16], who were admitted to a tertiary care hospital between 2016 and 2019. Primary outcome measure was myocardial injury according to the fourth Universal Definition (= high sensitive troponin T ≥ 14 ng/l). Secondary endpoints were in-hospital major adverse cardiovascular events (MACE) and mortality. Main exposure was defined as administration of TXA during prehospital period. We conducted multivariate logistic regression models including predefined covariables. A total of 368 patients were screened. Among the 297 included patients (72% male, age. 55?21 years), 119 (40%) presented myocardial injury at hospital arrival. TXA was administered to 20/297 (7%) patients in the prehospital setting, and in 96/297 (32%) patients during pre-or in-hospital period. MACE incidence was 9% (26/297) and in-hospital mortality was 26% (76/297). The adjusted odds ratios (OR) for prehospital TXA and myocardial injury, MACE and mortality were 0.75 [95% confidence interval (CI): 0.25–2.23], 0.51 [95%CI: 0.06–4.30] and 0.84 [0.21–3.33], respectively. In the present cohort of patients suffering from severe trauma, prehospital TXA did not affect the incidence of myocardial injury.

Incidence of MACE in Patients Treated With CAR-T Cell Therapy: A Prospective Study

BackgroundPrevious retrospective studies have shown that chimeric antigen receptor T (CAR-T) cell therapy may be associated with major adverse cardiovascular events (MACE), especially in the context of cytokine-release syndrome (CRS) events. ObjectivesThe aim of this prospective observational study was to define the occurrence of MACE in adults undergoing treatment with CAR-T cell therapy and identify associated risk factors. MethodsVital signs, blood samples, and an echocardiogram were collected prior to and 2 days, 1 week, 1 month, and 6 months after CAR-T cell infusion, and charts were consulted at 12 months. In the event of CRS, echocardiography was repeated within 72 hours. MACE were defined as cardiovascular death, symptomatic heart failure, acute coronary syndrome, ischemic stroke, and de novo cardiac arrhythmia. ResultsA total of 44 patients were enrolled (mean age 58 ± 11 years, 77% men). The median follow-up duration was 487 days (Q1-Q3: 258-622 days). There were 24 episodes of CRS in 23 patients (52%) (13 grade 1, 10 grade 2, and 1 grade 3), with a median time to CRS of 4 days. Two patients had MACE (heart failure with preserved ejection fraction and atrial fibrillation) within 1 year and 6 and 7 days after CAR-T cell infusion. There was no change in left ventricular ejection fraction, but a modest decrease in global longitudinal strain was noted. ConclusionsThere were few cardiac effects associated with contemporary CAR-T cell therapy. As MACE occurred after CRS episodes, aggressive treatment and close follow-up during CRS events are essential.

Effect of Lipid-Lowering Drugs on Renal and Cardiovascular Outcomes in Patients with Chronic Kidney Disease and Dyslipidemia: ARetrospective Cohort Study.

The effects of lipid-lowering drugs (LLDs) on cardiovascular and renal outcomes in patients with advanced chronic kidney disease (CKD) and dyslipidemia are not completely understood. We conducted a retrospective cohort study to evaluate the effect of LLDs on end-stage kidney disease (ESKD), major adverse cardiovascular events (MACEs), and mortality in adult patients with CKD stage 3b, 4, or 5, and dyslipidemia. Participants were recruited between January 1, 2008, and December 31, 2018, and classified as LLD or non-LLD users; the final follow-up date was December 31, 2020. The primary outcome was time to ESKD or death due to renal failure. Sub-distribution hazard regression models adjusted for multivariables, including time-varying lipid profile covariates, were used for the analysis. Among the 6,740 participants, 4,280 patients with CKD and dyslipidemia, including 872 using LLDs and 3,408 not using LLDs, completed the primary analysis. The multivariable analyses showed that LLD users had a significantly lower risk of time to the composite renal outcome (adjusted hazard ratio [aHR], 0.76, 95% confidence interval [CI], 0.65-0.89), and MACE incidence (aHR, 0.75, 95% CI, 0.62-0.93) than did non-LLD users. After adjusting for time-varying covariates of the lipid profile, there was a significant difference in the composite renal outcome (aHR, 0.78, 95% CI, 0.65-0.93) and MACEs (aHR, 0.77, 95% CI, 0.60-0.98). Among adult patients with advanced CKD and dyslipidemia, LLD users had a significantly lower risk of composite renal outcomes and MACEs than non-LLD users. In addition to reducing lipid profile, the use of LLD is associated with renal and cardiovascular protective effects.

Aortic stiffness effectively risk stratifies diabetic patients with suspected myocardial ischemia undergoing vasodilatory stress perfusion cardiac magnetic resonance

Background and aimsCardiovascular magnetic resonance (CMR) comprehensively assesses aortic stiffness and myocardial ischemia in a single examination. Aortic stiffness represents a subclinical marker of cardiovascular risk in the general population, including patients with diabetes mellitus. However, there is no prognostic data regarding aortic stiffness in patients with diabetes mellitus undergoing stress perfusion CMR.MethodsConsecutive patients with diabetes mellitus with suspected myocardial ischemia referred for adenosine stress perfusion CMR with aortic pulse wave velocity (PWV) during 2010–2013 were studied. The primary outcome was major adverse cardiovascular events (MACE), defined as the composite of cardiac mortality, nonfatal myocardial infarction (MI), hospitalization for heart failure, coronary revascularization (> 90 days post-CMR), and ischemic stroke. The secondary outcome was hard cardiac events, defined as the composite of cardiac mortality and nonfatal MI.ResultsA total of 424 patients (median follow-up 7.2 years) were included. The mean PWV was 12.16 ± 6.28 m/s. MACE and hard cardiac events occurred in 26.8% and 9.4% of patients, respectively. Patients with elevated PWV (> 12.16 m/s) had a significantly higher incidence of MACE (HR 2.14 [95%CI 1.48, 3.09], p < 0.001) and hard cardiac events (HR 2.69 [95%CI 1.42, 5.10], p = 0.002) compared to those with non-elevated PWV. Multivariable analysis demonstrated that PWV independently predicts MACE (p = 0.003) and hard cardiac events (p = 0.01). Addition of PWV provided incremental prognostic value beyond clinical data, left ventricular mass index, myocardial ischemia, and late gadolinium enhancement in predicting MACE (incremental χ² 7.54, p = 0.006) and hard cardiac events (incremental χ² 5.99, p = 0.01).ConclusionsAortic stiffness measured by CMR independently predicts MACE and hard cardiac events and confers significant incremental prognostic value in patients with diabetes mellitus with suspected myocardial ischemia. Aortic stiffness measurement could potentially be considered as part of a stress perfusion CMR protocol to enhance risk prediction in patients with diabetes mellitus.

Elevated triglyceride levels are associated with increased risk for major adverse cardiovascular events in statin-naïve rheumatoid arthritis patients: A nationwide cohort study

ObjectivesTo investigate the association between the four components of the lipid profile (total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)) at baseline and composite major adverse cardiovascular events (MACEs) in statin-naïve rheumatoid arthritis (RA) patients with no previous history of cardiovascular events. MethodsThis nationwide population-based cohort study was performed on a total of 15,216 statin-naïve RA patients. The end point was a composite of clinical events, including myocardial infarction (MI), stroke, coronary revascularization, and cardiovascular death. We compared the incidence of and risk for clinical events according to each lipid variable. ResultsDuring follow-up (median 4.70 years), the incidence of MACE per 1000 person-years was 7.27. Among the four lipid components, only higher baseline TG levels were significantly associated with increased risk for composite MACE in RA subjects. The risk for composite MACE was significantly higher in the third (adjusted hazard ratio (HR), 1.35 [95% confidence interval (CI), 1.03–1.78]) and highest quartiles (adjusted HR, 1.74 [95%CI, 1.33–2.28]) of baseline TG level versus the lowest quartile. ConclusionsIn statin-naïve RA patients, increased TG level is associated with increased risk for MACE. Therefore, screening and intervention for increased TG level may be clinically beneficial in this population.

Cardiovascular Risk in Prostate Cancer Patients Using Luteinizing Hormone-Releasing Hormone Agonists or a Gonadotropin-Releasing Hormone Antagonist.

Luteinizing hormone-releasing hormone (LHRH) agonists are believed to have higher cardiovascular risk relative to gonadotropin-releasing hormone (GnRH) antagonists. However, previous studies have not consistently demonstrated this. We used real-world clinical practice data to evaluate differences in major adverse cardiovascular events (MACE) risk between LHRH agonists compared to a GnRH antagonist following androgen deprivation therapy (ADT) initiation. We performed a retrospective analysis of data in the Decision Resources Group (now Clarivate) Real World Evidence repository, which represents >300 million US patients from 1991 to 2020 across all US regions. Patients with prostate cancer who received at least 1 injection of ADT were included. The risks of MACE and all-cause mortality as independent endpoints were evaluated, Kaplan-Meier curves were constructed, and associations between MACE and all available confounding risk factors were evaluated by Cox regression analysis using Statistical Package for the Social Sciences. A total of 45,059 men with prostate cancer treated with ADT were analyzed. Overall, the risks of MACE and all-cause mortality were slightly lower in the first year after ADT initiation compared to subsequent years. MACE risk was higher for the GnRH antagonist compared to LHRH agonists (HR=1.62; 95% CI 1.21-2.18, P = .001). The risk of all-cause mortality was also higher for the GnRH antagonist vs LHRH agonists (HR=1.87; 95% CI 1.39-2.51, P < .001). The adjusted incidence of MACE was higher for men treated with the GnRH antagonist compared to the LHRH agonists. The demographic and risk factors with the greatest impact on MACE risk were higher age, baseline metastasis, oncology (vs urology) setting, personal MACE history, antagonist (vs agonist), tobacco history, White (vs Black) race, and lower BMI.

Cardiovascular Adverse Events Associated With New-Generation Androgen Receptor Pathway Inhibitors (ARPI) for Prostate Cancer: A Disproportionality Analysis Based on the FDA Adverse Event Reporting System (FAERS).

The potential cardiovascular adverse events associated with new-generation androgen receptor pathway inhibitors (ARPI) in the treatment of prostate cancer remain unclear. We aimed to assess the pharmacovigilance (PV), reporting rate, severity, and reaction outcomes of major adverse cardiovascular events (MACE) related to new-generation ARPI for prostate cancer reported to the United States Food and Drug Administration Adverse Event Reporting System (FAERS). We analyzed reports of cardiovascular adverse events associated with drug therapy for prostate cancer submitted to FAERS between January 2014 and December 2022. Three primary new-generation ARPIs were identified: abiraterone acetate, enzalutamide, and apalutamide. Our primary composite endpoint was the PV of MACE caused by ARPIs in the treatment of prostate cancer, and the secondary endpoint was PV of other cardiovascular events. The software implemented was STATA 17.0 MP. A total of 278,031 suspected drug-adverse event pairs related to drug treatment in patients with prostate cancer were identified, of which 10,861 reports were cardiovascular events, including 5800 reports of MACE and 5061 reports of other cardiovascular events. The majority of these cardiovascular adverse event reports came from the United States (36.6%) and were mostly older men (age 76.0 ± 8.6 years). Compared with enzalutamide, the constituent ratio of MACE caused by abiraterone acetate and apalutamide was significantly increased, but the incidence of severe MACE decreased significantly. The PV signal regarding MACE was detected in abiraterone acetate and apalutamide but not in enzalutamide. Abiraterone acetate and apalutamide presumably are associated with a higher risk of MACE than enzalutamide in new-generation ARPI for prostate cancer. More extensive prospective studies and more extended follow-up periods need to confirm this further.

A Low Arginine/Ornithine Ratio is Associated with Long-Term Cardiovascular Mortality.

The long-term prognostic value of the bioavailability of L-arginine, an important source of nitric oxide for the maintenance of vascular endothelial function, has not been investigated fully. We therefore investigated the relationship between amino acid profile and long-term prognosis in patients with a history of standby coronary angiography. We measured the serum concentrations of L-arginine, L-citrulline, and L-ornithine by high-speed liquid chromatography. We examined the relationship between the L-arginine/L-ornithine ratio and the incidence of all-cause death, cardiovascular death, and major adverse cardiovascular events (MACEs) in 262 patients (202 men and 60 women, age 65±13 years) who underwent coronary angiography over a period of ≤ 10 years. During the observation period of 5.5±3.2 years, 31 (12%) patients died, including 20 (8%) of cardiovascular death, while 32 (12%) had MACEs. Cox regression analysis revealed that L-arginine/L-ornithine ratio was associated with an increased risk for all-cause death (unadjusted hazard ratio, 95% confidence interval) (0.940, 0.888-0.995) and cardiovascular death (0.895, 0.821-0.965) (p＜0.05 for all). In a mod el adjusted for age, sex, hypertension, hyperlipidemia, diabetes, current smoking, renal function, and log10-transformed brain natriuretic peptide level, cardiovascular death (0.911, 0.839-0.990, p=0.028) retained an association with a low L-arginine/ L-ornithine ratio. When the patients were grouped according to an L-arginine/L-ornithine ratio of 1.16, the lower L-arginine/L-ornithine ratio group had significantly higher incidence of all-cause death, cardiovascular death, and MACEs. A low L-arginine/L-ornithine ratio may be associated with increased 10-year cardiac mortality.

Smoking and cardiovascular disease in patients with type 2 diabetes: a prospective observational study.

Cigarette smoking is a major risk factor for cardiovascular disease. In type 2 diabetes mellitus (T2D), medications such as antihypertensives and statins can reduce the increased cardiovascular risk. The aim of this study was to evaluate the impact of cigarette smoking on major adverse cardiovascular event (MACE) and all-cause mortality in patients with T2D in a relatively well treated Swedish cohort. Seven hundred and sixty-one patients with T2D aged 55-66 years were followed in the prospective observational CArdiovascular Risk factors in patients with DIabetes - a Prospective study in Primary care (CARDIPP) study. Baseline data included blood samples of markers of dysglycemia and inflammation, blood pressure as well as questionnaire responses regarding cigarette smoking. Participants were followed for incidence of MACE and all-cause mortality. Of the included 663 participants, the mean age was 60.6 (SD 3.1) years and 423 (63.8%) were men. Levels of C-reactive protein and vitamin D, as well as the proportion of participants treated with antihypertensives, acetylic salicylic acid, statins, and diabetes medications, were similar between smokers and nonsmokers. Median follow-up time was 11.9 (Q1-Q3 10.8-12.7) years. Cigarette smoking was associated with all-cause mortality [hazard ratio 2.24 (95% confidence interval, 95% CI 1.40-3.56), P < 0.001], but not MACE [hazard ratio 1.30 (95% CI 0.77-2.18), P = 0.328]. In patients with T2D, cigarette smoking was not associated with an increased risk of MACE. This raises the question of whether cardioprotective drugs in individuals with T2D to some degree mitigate the cardiovascular harm of smoking, even though they do not affect other dire consequences of smoking.

Association between the atherogenic index of plasma and adverse long-term prognosis in patients diagnosed with chronic coronary syndrome

BackgroundThe Atherogenic Index of Plasma (AIP) is a newly identified biomarker associated with lipid metabolism, demonstrating significant prognostic capabilities in individuals diagnosed with cardiovascular disease. However, its impact within the context of chronic coronary syndromes (CCS) remains unexplored. Thus, the present investigation sought to examine the potential association between AIP levels and long-term clinical outcomes in patients diagnosed with CCS.MethodsA total of 404 patients diagnosed with CCS and who underwent coronary angiography were included in this study. The AIP index was calculated as log (triglycerides / high-density lipoprotein-cholesterol). The patients were categorized into four groups based on their AIP values: Q1 (< -0.064), Q2 (-0.064 to 0.130), Q3 (0.130 to 0.328), and Q4 (> 0.328). The occurrence of major adverse cardiovascular events (MACE) was monitored during the follow-up period for all patients. Cox regression analysis and Kaplan-Meier curve analysis were employed to examine the relationship between AIP and MACE. Furthermore, ROC analysis was utilized to determine the optimal cut-off value of AIP for predicting clinical MACE.ResultsDuring the median 35 months of follow-up, a total of 88 patients experienced MACE. Notably, the group of patients with higher AIP values (Q4 group) exhibited a significantly higher incidence of MACE compared to those with lower AIP values (Q1, Q2, and Q3 groups) (31.7% vs. 16.8%, 15.7%, and 23.0% respectively; P = 0.023). The Kaplan-Meier curves illustrated those patients in the Q4 group had the highest risk of MACE relative to patients in the other groups (log-rank P = 0.014). Furthermore, the multivariate Cox regression analysis demonstrated that individuals in the Q4 group had a 7.892-fold increased risk of MACE compared to those in the Q1 group (adjusted HR, 7.892; 95% CI 1.818–34.269; P = 0.006). Additionally, the ROC curve analysis revealed an optimal AIP cut-off value of 0.24 for predicting clinical MACE in patients with CCS.ConclusionOur data indicate, for the first time, that AIP is independently associated with poor long-term prognosis in patients suffering from CCS. The optimal AIP cut-off value for predicting clinical MACE among CCS patients was 0.24.
