The Prognostic Value of Advanced Lung Cancer Inflammation Index in Elderly Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention.

This study aimed to investigate the predictive value of advanced lung cancer inflammation index (ALI) for major adverse cardiovascular events (MACEs) in elderly patients with acute coronary syndrome (ACS).A total of 586 ACS patients undergoing percutaneous coronary intervention (PCI) over 65 years old between January 2017 and December 2018 were retrospectively collected. The patients were divided into two groups by the optimal cutoff value of ALI. Spearman rank correlation coefficient was used to evaluate the correlation between ALI and the Global Registry of Acute Coronary Events (GRACE). Time-dependent receiver operating characteristic (ROC) curves, Cox survival analysis, and Kaplan Meier curves were used to assess the predictive value of ALI for MACEs.Spearman's nonparametric test revealed a moderate correlation between ALI and the GRACE (r: -0.417, P < 0.001). Time-dependent ROC curves showed that the area under the curve for ALI was 0.751 (95% CI, 0.699-0.798) in predicting MACEs, higher than Geriatric Nutritional Risk Index (0.531, 95% CI 0.435-0.627) and Prognostic Nutritional Index (0.590, 95% CI 0.505-0.676), and for combined diagnostic models (ALI + GRACE) was 0.913, (95% CI 0.875 - 0.942, P < 0.001). Multivariate Cox analysis demonstrated that ALI (HR: 0.974, 95% CI: 0.952-0.996, P = 0.017) was an independent risk factor for MACEs. Kaplan Meier survival analysis showed that the cumulative incidence of MACEs was significantly higher in elderly ACS patients with lower ALI (log-rank test, P < 0.001).ALI could be a nutrition-inflammation indicator with independent predictive value for long-term MACEs of elderly ACS patients after PCI.

Association of liver fibrosis-4 index with adverse outcomes in hypertrophic cardiomyopathy patients.

The fibrosis-4 index (FIB-4) is a non-invasive tool to assess fibrosis risk in chronic liver disease. We aimed to explore the relationship between the FIB-4 index and long-term major adverse cardiovascular events (MACE) in HCM patients. Consecutive patients diagnosed with HCM were included. Patients were divided into two groups using a defined cutoff value established through a ROC analysis for predicting MACE (FIB-4≥2.37 and FIB-4<2.37). The final analysis comprised 187 HCM patients (34.8% females, 66.49±11.43years of age), with 47 (25.1%) in the FIB-4≥2.37 group and 140 (74.9%) in the FIB-4<2.37 group. Among these, 147 (78.6%) individuals had complete follow-up data. Patients with FIB-4≥2.37 demonstrated a higher prevalence of co-morbidities such as atrial fibrillation (27.7% vs. 7.9%; P<0.001), heart failure (55.3% vs. 24.3%; P<0.001), elevated NT-proBNP levels (3.03±4.74 vs. 0.66±1.08; P<0.001), and lower LVEF (58.51±7.86 vs. 61.84±5.04; P=0.001). Over a median of 41 (IQR 16-63) months follow-up, MACE occurred in 49 (33.3%), with a significantly higher incidence in the FIB-4≥2.37 group (58.8% vs. 25.7%, P<0.001). Cardiac death rates were also elevated in the FIB-4≥2.37 group (20.6% vs. 2.7%, P=0.001). Cox regression analysis revealed an independent association between FIB-4≥2.37 and a higher risk of MACE (adjusted HR: 1.919, 95% CI 1.015-3.630; P=0.045) and cardiac death (adjusted HR: 9.518, 95% CI 1.718-52.732; P=0.010). Furthermore, the FIB-4 index shows positive correlations with left atrium diameter (r=0.229; P=0.003), septal thickness (r=0.231; P=0.002), posterior wall thickness (r=0.235; P=0.001), and NT-proBNP (r=0.271; P<0.001). Conversely, a negative correlation was observed between the FIB-4 index and left ventricular ejection fraction (r=-0.185; P=0.011). Elevated FIB-4 index, indicative of liver fibrosis, is independently associated with an increased risk of long-term MACE in HCM patients. This emphasizes the potential influence of liver function abnormalities on HCM prognosis, underscoring the need for comprehensive risk assessment in clinical management.

Brain natriuretic peptide is a long-term cardiovascular predictor in carotid endarterectomy

Background In noncardiac surgery, several biomarkers are known to play a role in predicting long-term complications, such as major adverse cardiovascular events (MACE), myocardial infarction, or death. Carotid endarterectomy (CEA) is considered a low to medium-risk surgery for carotid stenosis aimed at preventing stroke events. Brain natriuretic peptide (BNP) is a biomarker with potential prognostic value regarding MACE. Since its role in patients undergoing CEA is unknown, this study aims to assess the potential role of BNP as a short and long-term predictor of all-cause mortality and MACE in patients undergoing CEA. Methods From a prospective database, patients who underwent CEA under regional anesthesia (RA) at a tertiary hospital center were enrolled, and a post hoc analysis was conducted. Patients on which BNP levels were measured up to fifteen days before surgery, and two groups based on the BNP threshold (200 pg/mL) were defined and compared. Kaplan Meier survival curves and adjusted hazard ratios (aHR) were assessed by multivariable Cox regression. The primary outcome was the incidence of long-term MACE and all-cause mortality. Secondary outcomes included the incidence of AMI and AHF. Results A total of 89 patients were evaluated. The mean age of the cohort was 71.2 ± 8.7 years, with 71 (79.8%) males, and presented a median follow-up of 30 [13.5–46.4] months. BNP > 200 pg/mL has demonstrated positive predictive value for MACE (aHR: 5.569, confidence interval (CI): 2.441–12.7, p < 0.001) and all-cause mortality (aHR: 3.469, CI: 1.315–9.150, p = 0.018). Conclusion BNP has been demonstrated to independently predict long-term all-cause mortality, MACE and AMI following CEA. It serves as a low-cost, ready-to-use biomarker, although further studies are necessary.

Early coronary angiography in NSTEMI: a regional Victorian perspective.

Current guidelines highlight a paucity of evidence guiding optimal timing for non-ST-elevation myocardial infarction (NSTEMI) in high-risk and non-high-risk cases. We assessed long-term major adverse cardiovascular events (MACEs) in NSTEMI patients undergoing early (<24 h) versus delayed (>24 h) coronary angiography at 6 years. Secondary end-points included all-cause mortality and cumulative MACE outcomes. Baseline characteristics and clinical outcomes were assessed among 355 patients presenting to a tertiary regional hospital between 2017 and 2018. Cox proportional hazard models were generated for MACE and all-cause mortality outcomes, adjusting for the Global Registry of Acute Coronary Events (GRACE) score, patient demographics, biomarkers and comorbidities. Two hundred and seventy patients were included; 147 (54.4%) and 123 (45.6%) underwent early and delayed coronary angiography respectively. Median time to coronary angiography was 13.3 and 45.4 h respectively. At 6 years, 103 patients (38.1%) experienced MACE; 41 in the early group and 62 in the delayed group (hazard ratio (HR) = 2.23; 95% confidence interval (CI) = 1.50-3.31). After multivariable adjustment, the delayed group had higher rates of MACE (HR = 1.79; 95% CI = 1.19-2.70), all-cause mortality (HR = 2.76; 95% CI = 1.36-5.63) and cumulative MACE (incidence rate ratio = 1.54; 95% CI = 1.12-2.11). Subgroup analysis of MACE outcomes in rural and weekend NSTEMI presentations was not significant between early and delayed coronary angiography (HR = 1.49; 95% CI = 0.83-2.62). Higher MACE rates in the delayed intervention group suggest further investigation is needed. Randomised control trials would be well suited to assess the role of early invasive intervention across all NSTEMI risk groups.

Blood group is a long-term cardiovascular risk factor after carotid endarterectomy

Background ABO blood group system has been clinically related to an increased incidence of cardiovascular diseases. Preliminary data relating Rhesus (Rh) factor and these outcomes also have been published. Our aim was to analyse the impact of blood group on the short and long-term outcomes after carotid endarterectomy (CEA). Materials and methods From 2012 to 2019, patients from a referral centre who underwent CEA for atherosclerotic carotid stenosis were prospectively followed. Our primary outcomes were long-term major adverse cardiovascular events (MACEs) and all-cause mortality. Secondary outcomes were perioperative complications and myocardial injury after non-cardiac surgery (MINS). Median follow-up was 50 months (interquartile range 21–69). Time-to-event analysis was used to determine the effect of ABO and Rh groups in long-term outcomes. Results One hundred and eighty-four patients were included, with a mean age of 70.1 ± 9.1 years. Eighteen (25.7%) patients with O type and 48 (42.1%) patients with non-O type presented coronary artery disease (odds ratio [OR]: 2.313, 5–95% confidence interval (CI) 1.245–4.297, p = .008). Patients Rh+ presented significantly more congestive heart failure, 23 (14.7%), p = .03. The incidence of MACE in the long-term was higher in non-O patients (adjusted hazard ratio: 2.034; CI: 1.032–4.010, p = .040). Rh− patients, presented a higher incidence of perioperative MINS. However, there was no statistically significant association with long-term risk of MACE. Conclusion The incidence of MACE in long-term analysis was higher in non-O blood type and 30-day MINS was significantly more common amongst Rh− patients. The benefit from a more complete preoperative cardiac study in these patients should be performed.

Impact of Multiarterial Revascularization on Long-term Major Adverse Cardiovascular Events After Coronary Bypass in 23,798 Patients

BackgroundThis study evaluated the association between bypass grafting with multiarterial grafts (MAG) and single arterial grafts (SAG) and all-cause mortality and major adverse cardiovascular and cerebrovascular events (MACCE), overall and across different patient subgroups from a Middle Eastern nation. MethodsThis single-center retrospective cohort study included 23,798 patients. MAG and SAG groups were balanced using inverse probability weighting (IPW). Associations between MAG and outcomes were assessed using Cox regression. A series of covariate-adjusted Cox models were conducted to evaluate the effect of MAG on outcomes at different levels of independent variables, including age, sex, and cardiovascular risk factors. ResultsIn the study population (73.9% were men, 65.11 ± 9.94 years), 986 patients (4.1%) underwent MAG. Compared with the SAG group, MAG had lower crude mortality (14.1% vs 21.6%) and MACCE (28.8% vs 34.7%) rates during a median follow-up of 9.23 years (quartile 1-quartile 3, 9.13-9.33 years). Although MAG was significantly associated with reduced risk of study outcomes at the univariate level, these associations disappeared after matching (all-cause mortality (IPW hazard ratio, 0.90; 95% CI, 0.67-1.22) and MACCEs (IPW hazard ratio, 0.94; 95% CI, 0.76-1.15). However, covariate-adjusted models indicated that MAG was associated with a significantly reduced risk of adverse events, particularly MACCEs, in men, younger patients, and those without risk factors. ConclusionsMAG was not associated with improved postsurgery outcomes among the total coronary artery bypass graft population. Our findings, however, should be interpreted in the context of a relatively low total institutional MAG burden. Choosing a second arterial conduit over saphenous vein grafts in specific patient subgroups might be reasonable. This hypothesis-generating finding should be investigated in future clinical trials in these patients.

Association Between Systemic Immune-Inflammation Index and Adverse Outcomes in Patients With Acute Coronary Syndrome: A Meta-Analysis.

The systemic immune-inflammation index (SII) has been developed for the risk prognostication of acute coronary syndrome (ACS) patients. This meta-analysis aimed to assess the value of SII for predicting adverse outcomes in ACS patients. Relevant studies were identified by searching the PubMed, Web of Science, and Embase databases. Studies that investigated the association of SII with all-cause mortality or major adverse cardiovascular events (MACEs) in ACS patients were eligible. The short-term outcomes were defined as adverse events occurring during the hospital and within 30days. 11 studies with 16,596 patients were eligible for analysis. A random effect meta-analysis indicated that a higher SII level significantly predicted short-term death (hazard ratios [HR] 2.60; 95% confidence intervals [CI] 1.29-5.25) and long-term all-cause mortality (HR 2.40; 95% CI 1.25-4.59), even after adjusting for traditional confounding factors. Additionally, a higher SII level was also significantly associated with an increased risk of short-term MACEs (HR 1.61; 95% CI 1.28-2.03) and long-term MACEs (HR 2.43; 95% CI 1.74-3.40). These findings suggest that SII level has a strong prognostic value for both MACEs and all-cause mortality in patients with ACS. Determining the SII level has the potential to improve risk prognostication in ACS patients.

Modulation of the intestinal microbiota as a new strategy for the prevention and treatment of comorbid chronic cardiovascular diseases and colorectal cancer in one patient. Review

To date, the etiological causes of adverse outcomes associated with cardiovascular diseases and concomitant colorectal cancer in one patient, especially over 60 years of age, are multifactorial: from undiagnosed timely above-mentioned pathological conditions to poor adherence to treatment. It is a multi-level approach that is the future guarantee of reducing the burden on public health as a result of these most common nosologies.The aim of the work is to evaluate discussions between different experts with an analysis of fundamental and clinical studies based on world literature in the search for new prospects for the treatment of patients with cardiovascular pathology and comorbid colorectal cancer based on the composition and function of the intestinal microbiota.A literature search was conducted in the PubMed electronic database using the keywords: intestinal microbiota, cardio-oncology, oncosurgery, colorectal cancer, cardiovascular diseases. Additional sources were identified through literature cross-referencing. Search period: 2023.The gut microbiome is a potential marker for better risk stratification of cardiovascular diseases, colorectal cancer, and prediction of shortand long-term major adverse cardiovascular and cancer events. To develop clear recommendations and conclusions, additional research is required.

Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest Score is a Long-Term Cardiovascular Risk Predictor After Aortoiliac Revascularization

Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest (MICA) is a validated self-explanatory score applied in cardiac or noncardiac surgeries. This study aims to assess the predictive value of the MICA score for cardiovascular events after aortoiliac revascularization. This prospective cohort underwent elective aortoiliac revascularization between 2013 and 2021. Patients' demographic, clinical characteristics, and outcomes were registered. The patients were divided into 2 groups according to the MICA score using optimal binning. Survival analysis to test for time-dependent variables and multivariate Cox regression analysis for independent predictors were performed. This study included 130 patients with a median follow-up of 55months. Preoperative MICA score was ≥6.5 in 41 patients. MICA ≥6.5 presented a statistically significant association, with long-term occurrence of acute heart failure (HR=1.695, 95% CI 1.208-2.379, P=0.002), major adverse cardiovascular events (HR=1.222, 95% CI 1.086-1.376, P<0.001), and all-cause mortality (HR=1.256, 95% CI 1.107-1.425, P<0.001). Multivariable Cox regression confirmed MICA as a significant independent predictor of long-term major adverse cardiovascular events (aHR=1.145 95% CI 1.010-1.298, P=0.034) and all-cause mortality (aHR=1.172 95% CI 1.026-1.339, P=0.020). The MICA score is a quick, easy-to-obtain, predictive tool in identifying patients with a higher risk of postaortoiliac revascularization cardiovascular events, such as acute heart failure, major adverse cardiovascular events, and all-cause mortality. Additional research for the validation of the MICA score in the context of aortoiliac revascularization and specific interventions is necessary.

The Role of QRS Complex and ST-Segment in Major Adverse Cardiovascular Events Prediction in Patients with ST Elevated Myocardial Infarction: A 6-Year Follow-Up Study.

as a relatively high number of ST-segment elevation myocardial infarction (STEMI) patients develop major adverse cardiovascular events (MACE) following percutaneous coronary intervention (PCI), our aim was to determine the significance, and possible predictive value of QRS complex width and ST-segment elevation. our patient sample included 200 PCI-treated STEMI patients, which were divided into two groups based on the following duration of symptoms: (I) less than 6 h, and (II) 6 to 12 h. For every patient, an ECG was performed at six different time points, patients were followed for up to six years for the occurrence of MACE. the mean age was 60.6 ± 11.39 years, and 142 (71%) were male. The 6-12 h group had significantly wider QRS complex, higher ST-segment elevation, lower prevalence of ST-segment resolution as well as MACE prevalence (p < 0.05). ECG parameters, QRS width, and magnitude of ST-segment elevation were proved to be independent significant predictors of MACE in all measured time points (p < 0.05). Even after controlling for biomarkers of myocardial injury, these ECG parameters remained statistically significant predictors of MACE (p < 0.05). our study highlights that wider QRS complex and a more pronounced ST-segment elevation are associated with longer total ischemic time and higher risk of long-term MACE.

Effects of Preoperative Nutritional Status and Lymphocyte Count on the Development of Early-term Atrial Fibrillation After Coronary Artery Bypass Grafting: A Retrospective Study.

Although there are publications in the literature stating that parameters related to the nutritional status of patients are associated with the clinical outcomes of those with coronary artery disease, it is also stated that there is insufficient data on the relationship between nutritional indices and long-term outcomes and major adverse cardiovascular events in patients undergoing isolated coronary artery bypass grafting. This retrospective study was conducted with patients who underwent isolated elective on-pump coronary artery bypass grafting in our hospital. Patients who underwent emergency coronary artery bypass grafting or those with known atrial fibrillation in the preoperative period were excluded. Patients were analyzed and compared in two groups according to the development of postoperative atrial fibrillation. The data of 93 coronary artery bypass grafting patients (71 [76%] males) with a mean age of 62.86 ± 9.53 years included in the study were evaluated. Both groups had similar preoperative ejection fraction value, hemoglobin level, age, number of distal bypasses, and postoperative mortality rates. Although the mean cardiopulmonary bypass and aortic cross-clamping times were higher in Group 1, they were not statistically significant. In our study, the mean prognostic nutrition index value was 51.76 ± 3002. According to our study results, there was no statistically significant difference between prognostic nutrition index values and the development of atrial fibrillation after coronary artery bypass grafting, which is similar to some publications in the literature. We think that it would be beneficial to conduct randomized studies involving more patients on this subject.

Procedural Results and Long-term Outcome of Chronic Total Occlusion Percutaneous Coronary Intervention in a UK Non-surgical Centre.

Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has evolved a great deal over recent years, with increased procedural success and lower complication rates being reported. This study aims to evaluate the feasibility, safety and success of a dedicated CTO programme in a large UK PCI centre without on-site cardiothoracic surgery facilities. Clinical and procedural data were retrospectively collected for consecutive unselected patients undergoing CTO PCI between 2015 and 2019 from the local database and regional electronic patient records. In-hospital outcomes and long-term major adverse cardiovascular events (all-cause mortality, MI, stroke and target vessel revascularisation) were recorded. A total of 170 patients underwent 191 CTO procedures during the study period. The mean age was 63 ± 10 years and 80.6% of patients were male (n=137). The clinical indications were: stable chronic coronary syndromes in 88.5% (n=169) of patients; staged procedures in the context of acute coronary syndromes in 1.6% (n=3); and presentation with acute coronary syndrome in 9.9% (n=19). The procedural success rate was 50.0% (n=25) for general interventional cardiologists and 90.1% (n=127) for dedicated CTO operators. In-hospital major adverse cardiovascular events occurred once (0.5%) and interhospital transfer for emergency salvage cardiac surgery was not required. Long-term follow-up data at a median duration of 3.8 years revealed 4 (2.4%) cardiac deaths, 14 (8.3%) spontaneous MI events and 10 (5.9%) target vessel revascularisations. These data suggest CTO PCI using contemporary techniques is both safe and effective when undertaken in a high-volume non-surgical centre by experienced operators.

Long-Term Clinical Outcomes of Acute Kidney Disease in Patients Receiving Extracorporeal Membrane Oxygenation.

Extracorporeal membrane oxygenation (ECMO) is widely used; however, studies on the long-term outcomes of ECMO are scarce. We investigated the long-term clinical outcomes of acute kidney disease (AKD) in patients receiving ECMO. Electronic data (2009-2018) were retrospectively collected from a multicenter database. Patients were divided into two groups (AKD and non-AKD) according to their AKD status 8-90 days after the initiation of ECMO. Inverse probability of treatment weighting was used to balance baseline covariates between the two groups. The primary outcomes were major adverse kidney events (MAKEs) and major adverse cardiovascular events (MACEs), and the secondary outcomes were all-cause readmission, sepsis-related readmission, infection-related readmission, and dementia. Totally, 395 patients were eligible for analysis; of them, 160 patients (40.5%) developed AKD. The AKD group had a higher risk of MAKEs (hazard ratio [HR]: 2.06; 95% confidence interval [CI]: 1.68-2.53) than did the non-AKD group. Subgroup analysis revealed that the observed unfavorable effect of AKD on the risk of MAKEs was more pronounced in patients receiving venovenous ECMO than in those receiving venoarterial ECMO (HR: 5.69 vs. 1.85, respectively; p for interaction = 0.004). AKD group had a higher risk of MACE during the initial 3-year post-ECMO in comparison to those without (HR: 1.68; 95% CI: 1.22-2.30). Moreover, the risks of all-cause, sepsis-related, and infection-related readmissions were high in AKD survivors. AKD is associated with an increased risk of long-term MAKEs and initial 3-year MACE in ECMO recipients. In addition, AKD is associated with increased risks of all-cause, infection-related, and sepsis-related readmissions.

Clinical Outcomes of Surgical Revascularization Strategies Guided by Quantitative Flow Ratio in Primary Noncoronary Cardiac Surgery.

Information regarding quantitative flow ratio (QFR) usage in coronary artery bypass grafting (CABG) is lacking. We compared the incidence of postoperative long-term adverse cardiovascular and cerebrovascular events after QFR-guided or coronary angiography-guided adult cardiac surgery with concurrent bypass surgery. This study included 432 patients who underwent cardiopulmonary bypass (CPB) at our institution with at least 1 angiographical coronary artery lesion (diameter stenosis: 30% to 90%) between January 2015 and January 2016. The QFR of each patient was calculated. Patients who only underwent intraoperative coronary revascularization following the principles of optimal revascularization strategy were assigned to group A. Patients with coronary lesions not meeting the above criteria were placed in group B. The average number of distal anastomoses of patients with combined CABG in group B was similar to that in Group A (1.9±1.0 vs. 1.7±0.9; P=0.081). Group A had a shorter CPB duration (114.4±49.2 vs 135.8±55.2 minutes; P<0.001) and shorter aortic cross-clamping time (83.6±36.2 vs 101.1±40.6 minutes; P<0.001). The rates of perioperative mortality and major complications did not differ between groups. Long-term major adverse cardiovascular and cerebrovascular events (MACCEs) were less common in group A than in group B (14.7% vs 29.5%; P<0.001). In primary noncoronary cardiac surgery, despite the similar average numbers of distal anastomoses, the group with target vessels treated using an optimal coronary revascularization strategy presented shorter CPB time and aortic cross-clamping time than the other group. Multivariate analyses also showed a lower incidence of long-term MACCEs.

Coronary Calcium Is Elevated in Patients with Myocardial Infarction without Standard Modifiable Risk Factors.

Objectives: Recent reports have highlighted myocardial infarction (MI) patients without standard modifiable risk factors (SMRF), noting them to be surprisingly common and to have a substantial risk of adverse outcomes. The objective of this study was to address the challenge of identifying at-risk patients without SMRF and providing preventive therapy. Methods: Patients presenting between 2001 and 2021 to Intermountain Health catheterization laboratories with a diagnosis of MI were included if they also had a coronary artery calcium (CAC) scan by computed tomography within 2 years. SMRF were defined as a clinical diagnosis or treatment of hypertension, hyperlipidemia, diabetes, or smoking. The co-primary endpoints in SMRF-less patients were: (1) proportion of patients with an elevated (>50%ile) CAC score, and (2) an indication for statin therapy (i.e., CAC ≥ 100 AU or ≥75%ile). The 60-day and long-term major adverse cardiovascular events were determined. A comparison set included MI patients with SMRF. Results: We identified 429 MI patients with a concurrent CAC scan, of which 60 had no SMRF. SMRF status did not distinguish most risk factors or interventions. No-SMRF patients had a high CAC prevalence and percentile (82% ≥ 50%ile; median, 80%ile), and 77% met criteria for preventive therapy. As expected, patients with SMRF had high CAC scores and percentiles. Outcomes were more favorable for No-SMRF status and for lower CAC scores. Conclusions: Patients without SMRF presenting with an MI have a high prevalence and percentile of CAC. Wider application of CAC scans, including in those without SMRF, is promising as a method to identify an additional at-risk population for MI and to provide primary preventive therapy.

Endothelial-Derived Microparticles Associate with Hospital Major Adverse Cardiovascular Events but not with Long-Term Adverse Events in Acute Myocardial Infarction

AbstractEndothelial-derived microparticles (EDMP) are markers of vascular function and convey roles in coagulation, inflammation, vasoactivity, angiogenesis, and cellular apoptosis, which implicate acute myocardial infarction (AMI). This study aimed to investigate whether, among AMI, on-admission EDMP counts affect hospital major adverse cardiovascular events (MACE) and whether the change of EDMP in 30-day posthospital discharge affects long-term follow-up MACE. The research design was a prospective cohort study. The subjects were 119 patients diagnosed and hospitalized with AMI, who were enrolled consecutively. The EDMP was measured on hospital admission and repeated 30-day posthospital discharge. The outcomes were in the hospital MACE comprised of cardiac mortality, heart failure, cardiogenic shock, reinfarction, and resuscitated ventricular arrhythmia. Furthermore, long-term follow-up were performed on 30-day, 90-day, and 1-year posthospital AMI discharge. The on-admission EDMP counts were significantly higher in subjects with hospital MACE compared with those without (median [interquartile range]: 27,421.0 [6,956.5–53,184.0] vs. 11,617.5 [4,599.0–23,336.7] counts/µL, p = 0.028). The EDMP counts cutoff value of &gt;26,810.0 counts/µL (52.4% sensitivity, 81.6% specificity) had significantly increased hospital MACE occurrence (adjusted odd ratio: 4.45, 95% confidence interval: 1.47–13.53, p = 0.008). The EDMP counts were significantly increased after 30-day posthospital discharge. Both on-admission and 30-day EDMP counts and the changes in EDMP counts did not impact MACE on the long-term follow-up. In conclusion, higher on-admission EDMP counts were independently associated with hospital MACE among AMI. However, on-admission and 30-day postdischarge EDMP and their changes did not impact long-term follow-up MACE.

Risk Score for Long-Term Survival and Major Adverse Cardiovascular and Cerebrovascular Events After Coronary Artery Bypass Grafting Surgery

To develop risk scoring models predicting long-term survival and major adverse cardiovascular and cerebrovascular events (MACCEs), including myocardial infarction and stroke after coronary artery bypass grafting (CABG). All 4,821 consecutive patients who underwent isolated CABG at Lankenau between January 2005 and July 2021 were included. MACCE was defined as all-cause mortality + myocardial infarction + stroke. Variable selection for both outcomes was obtained using a double-selection logit least absolute shrinkage and selection operator with adaptive selection. Model performance was internally evaluated by calibration and accuracy using bootstrap cross-validation. Mortality and MACCEs were compared in patients split into 3 groups based on the predicted risk scores for all-cause mortality and MACCEs. An external validation of our database was performed with 665 patients from the University of Brescia, Italy. Preoperative risk predictors were found to be predictors for all-cause mortality and MACCEs. In addition, being of African-American ethnicity is a significant predictor for MACCEs after isolated CABG. The areas under the curve (AUCs), which measures the discrimination of the models, were 80.4%, 79.1%, 81.3%, and 79.2% for mortality at 1, 2, 3, and 5 years follow-up. The AUCs for MACCEs were 75%, 72.5%, 73.8%, and 72.7% at 1, 2, 3, and 5 years follow-up. For external validation, the AUCs for all-cause mortality and MACCEs at 1, 2, 3, and 5 years were 73.7%, 70.8%, 68.7%, and 72.2% and 72.3%, 68.2%, 65.6%, and 69.6%, respectively. The Advanced (AD) Coronary Risk Score for All-Cause Mortality and MACCE provide good discrimination of long-term mortality and MACCEs after isolated CABG.

The Impacts of Nirmatrelvir-Ritonavir on Myocardial Injury and Long-Term Cardiovascular Outcomes in Hospitalized Patients with COVID-19 amid the Omicron Wave of the Pandemic.

Even though nirmatrelvir-ritonavir can improve the short-term morbidity and mortality in COVID-19 patients, the effects of this treatment on long-term major adverse cardiovascular events (MACEs), especially myocardial injury, remains undetermined. This prospective cohort study identified hospitalized adult patients with COVID-19 between April 19, 2022, and June 9, 2022, amid the omicron wave of the pandemic. Matched nirmatrelvir-ritonavir-treated and non-treatedcohorts were formed using the propensity score matching method. The primary outcome of this study was the incidence of MACEs (cardiovascular death, myocardial infarction, stroke, new-onset heart failure or heart failure hospitalization or ventricular arrhythmia) from 30 days to 16 months after the diagnosis of COVID-19. Two 949-patient cohorts with balanced baseline characteristics were formed by propensity score matching. Patients with nirmatrelvir-ritonavir, compared to those untreated, had a lower level of troponin I peak as well as the incidence of troponin I elevation. During the follow-up period, 59 patients in the nirmatrelvir-ritonavir group and 86 patients in the control group developed MACEs (P = 0.020). Regarding specific constituents of MACEs, the differences are mainly reflected in new-onset heart failure or heart failure hospitalization. COVID-19 clinical severity and troponin I peak were the independent predictors, while nirmatrelvir-ritonavir was the independent protective factor for the occurrence of MACEs in this population. Nirmatrelvir-ritonavir was effective in reducing myocardial injury as well as long-term adverse cardiovascular outcomes among hospitalized patients with COVID-19 amid the omicron wave of the pandemic.

Management and outcome in foreign-born vs native-born patients with myocardial infarction in Sweden.

Previous studies on disparities in healthcare and outcome have shown conflicting results. The aim of this study was to assess differences in baseline characteristics, management, and outcome in myocardial infarction (MI) patients, by country of birth. In total, 194 259 MI patients (64% male, 15% foreign-born) from the nationwide SWEDEHEART registry were included and compared by geographic region of birth. The primary outcome was one-year major adverse cardiovascular events (MACE) including all-cause death, MI, and stroke. Secondary outcomes were long-term MACE (up to 12 years), the individual components of MACE, 30-day mortality, management, and risk factors. Logistic regression, Cox proportional hazard models and propensity score matching (PSM), accounting for baseline differences, were used. Foreign-born patients were younger, often male, and had a higher cardiovascular (CV) risk factor burden, including smoking, diabetes, and hypertension. In PSM analyses, Asia-born patients had higher likelihood of revascularisation (OR 1.16, 95% CI 1.04-1.30), statins and betablocker prescription at discharge and a 34% lower risk of 30-day mortality. Furthermore, no statistically significant differences were found in the primary outcomes except for Asia-born patients having lower risk of one-year MACE (HR 0.85, 95% CI 0.73-0.98), driven by lower mortality (HR 0.72, 95% CI 0.57-0.91). The results persisted over long-term follow-up. This study shows that in a system with universal healthcare coverage in which acute and secondary preventive treatments do not differ by country of birth, foreign-born patients, despite higher CV risk factor burden, will do at least as well as native-born patients.
