The Predictive Value of Geriatric Nutritional Risk Index Combined with the GRACE Score in Predicting the Risk of One Year Poor Prognosis in Elderly Patients with Non-ST Segment Elevation Myocardial Infarction After PCI.

As a nutritional indicator, a lower level of geriatric nutritional risk index (GNRI) has been suggested as a predictor for poor prognosis in acute coronary syndrome (ACS). However, whether GNRI could improve the predictive value of the Global Registry of Acute Coronary Events (GRACE) score for the prognosis in elderly patients with non-ST segment elevation myocardial infarction (NSTEMI) after PCI remains unclear. A total of 446 elderly patients with NSTEMI after percutaneous coronary intervention (PCI) were consecutively enrolled. Patients were divided into major adverse cardiovascular and cerebrovascular events (MACCE) group and control group according to the occurrence of MACCE during one year follow up. The clinical parameters including GNRI were compared to investigate the predictors for MACCE. The performance after the addition of GNRI to the GRACE score for predicting MACCE was determined. A total of 68 patients developed MACCE. In unadjusted analyses, the rate of MACCE was significantly higher in the 93.8<GNRI <102.7 group and GNRI ≤ 93.8 group versus GNRI ≥ 102.7 group. The logistics regression model showed that age, GNRI, and GRACE score were independent predictors for MACCE in elderly patients with NSTEMI after PCI. The addition of the GNRI to the GRACE score significantly improved the prediction of MACCE in elderly patients with NSTEMI after PCI, increasing the C-index from 0.792 to 0.885 (p < 0.001); the NRI was 0.094 (95% CI, 0.004-0.177, p < 0.001), and the IDI was 0.011 (95% CI, 0.000-0.023, p < 0.001). Combining GNRI and GRACE score could significantly improve the predictive value of one year MACCE in elderly patients with NSTEMI after PCI. By using this combined new risk model, we could easily identify the high-risk populations in clinical practice, so as to better monitor and manage them.

Predictive Value of Plasma PCSK9 Levels for Degree of Atherosclerosis and Major Adverse Cardiovascular and Cerebrovascular Events in Older Adult Patients with Non-Alcoholic Fatty Liver Disease.

This study investigated the influence of plasma proprotein convertase subtilisin/kexin 9 (PCSK9) levels on the degree of atherosclerosis and major adverse cardiovascular and cerebrovascular events (MACCE) in older adults with non-alcoholic fatty liver disease. The degree of atherosclerosis severity was assessed by the standard Gensini score quartile method. According to the degree of atherosclerosis, patients were divided into mild (0-24 points; n=84), moderate (25-53 points; n=86), and severe groups (≥54 points; n=84) and then categorized as MACCE (n=30) or non-MACCE (n=224) according to 6-month follow-up data. The patients' age, sex, smoking history, medical history, and early morning fasting venous blood, for measuring biochemical indexes, were collected. Clinical data were compared between groups and the relationship between Gensini scores and PCSK9 was evaluated. Compared with the mild group, the moderate and severe groups had higher high-sensitivity C-reactive protein(hs-CRP), PCSK9, triglycerides(TG), low-density lipoprotein cholesterol (LDL-C), and lipoprotein(a)[Lp(a)] levels and lower high-density lipoprotein cholesterol(HDL-C) levels (all P<0.05). Moreover, PCSK9 positively correlated with Gensini scores (r=0.657, P<0.01). The MACCE and non-MACCE groups had significantly different ages, statin use, Gensini scores, PCSK9, and LDL-C (all P<0.05). Multi-factorial Cox risk regression analysis showed the Gensini score (HR=1.018, 95% CI: 1.006~1.029) and PCSK9 (HR=1.147, 95% CI: 1.038~1.287) were independent risk factors for MACCE. The Gensini score and PCSK9 levels can be used as predictive indicators for the degree of illness and occurrence of MACCE in older NAFLD patients.

The Impact of Microvascular Resistance Reserve on the Outcome of Patients With STEMI

BackgroundMicrovascular resistance reserve (MRR) can characterize coronary microvascular dysfunction (CMD); however, its prognostic impact in ST-segment elevation myocardial infarction (STEMI) patients remains undefined. ObjectivesThis study sought to investigate the prevalence of CMD in STEMI patients and to elucidate the prognostic performance of MRR. MethodsThis prospective cohort study enrolled 210 STEMI patients with multivessel disease who underwent successful revascularization and returned at 3 months for coronary physiology assessments with bolus thermodilution. The prevalence of CMD (MRR <3) and the association between MRR and major adverse cardiovascular and cerebrovascular events (MACCEs) at 12 months were investigated. ResultsThe median age of patients was 65 years, and 59.5% were men. At the 3-month follow-up, 56 patients (27%) had CMD (MRR <3.0). The number of MACCEs at 12 months was higher in patients with vs without CMD (48.2% vs 11.0%; P < 0.001). MRR was independently associated with 12-month MACCEs (HR: 0.45 per unit increase; 95% CI: 0.31-0.67; P < 0.001) and with stroke, heart failure, and poorer recovery in left ventricular systolic function. The areas under the receiver-operating characteristic curves for predicting MACCEs at 12 months with fractional flow reserve, coronary flow reserve (CFR), the index of microvascular resistance (IMR), and MRR were 0.609, 0.762, 0.781, and 0.743, respectively. The prognostic performance of CFR, IMR, and MRR were all comparable. ConclusionsThe novel parameter MRR is a prognostic marker of MACCEs in STEMI patients with a comparable performance to CFR and IMR.

OBSTRUCTIVE SLEEP APNEA REMAINS A RISK FACTOR FOR MAJOR ADVERSE CARDIOVASCULAR AND CEREBROVASCULAR EVENTS IN HYPERTENSVIE PATIENTS UNDER TREATMENT: THE UROSAH DATA

Objective: The impact of the co-occurrence of hypertension and obstructive sleep apnea (OSA) on the risk of long-term cardiovascular disease (CVD) outcomes has not been extensively studied in the Asian population, and the residual effect of OSA on CVD in patients under antihypertensive treatment is not clear. The study aimed to explore the impact of OSA on the risk of CVD outcomes in a large-scale Asian cohort under antihypertensive treatment using retrospective design. Design and method: Hypertensive patients who underwent polysomnography (PSG) test in January 2011 to December 2013 were recruited from the UROSAH cohort, which was conducted in Hypertension Center of People's Hospital. OSA was defined as apnea hypopnea index over 5. Outcomes were extended major adverse cardiovascular and cerebrovascular events (MACCE), including the first occurrence of nonfatal myocardial infarction, nonfatal stroke, revascularization, rehospitalization due to unstable angina or heart failure and all-cause death. Cox regression analysis was performed to explore the effect of OSA and hypertension coexistence on MACCE. Results: A total of 3329 hypertension patients were enrolled, of whom 2585 patients (about 77.7%) suffered from OSA. During a median follow-up period of 7.0 years, 415 patients developed extended MACCE. The incidence of extended MACCE was significantly greater in patients with OSA than those without OSA (hazard ratio [HR]: 1.59; 95% confidence interval [CI]: 1.27-1.99; P&lt;0.001). Overall, patients with OSA had an increased risk of cardiac events of 57% compared to those without OSA [HR (95%CI): 1.57 (1.04-2.39), P=0.034] and the association did not change in further sensitivity analysis. Particularly in uncontrolled hypertension, OSA was found to have a 93% increased risk of cardiac events, compared with patients without OSA (P=0.036). Conclusions: Untreated OSA seemed to be a factor affecting the prognosis of cardiac events in hypertensive patients, although the association between OSA and cardiac events would be attenuated by the pharmacological-induced blood pressure control, which highlights the need to treat OSA.

The Long-Term Prognostic Role of Nighttime Resting Heart Rate in Obstructive Sleep Apnea in Patients with Acute Coronary Syndrome.

A close relationship exists between resting heart rate (RHR) and obstructive sleep apnea (OSA). Still, the prognostic importance of nighttime RHR in patients with acute coronary syndrome (ACS) with or without OSA remains unclear. In this prospective cohort study, OSA was defined as an apnea-hypopnea index of ≥ 15 events/h, and the high nighttime RHR (HNRHR) was defined as a heart rate of ≥ 70 bpm. The primary endpoint was a major adverse cardiovascular and cerebrovascular event (MACCE), including cardiovascular death, myocardial infarction, stroke, ischemia-driven revascularization, or hospitalization for heart failure. Among the 1875 enrolled patients, the mean patient age was 56.3±10.5 years, 978 (52.2%) had OSA, and 425 (22.7%) were in HNRHR. The proportion of patients with HNRHR is higher in the OSA population than in the non-OSA population (26.5% vs. 18.5%; P＜0.001). During 2.9 (1.5, 3.5) years of follow-up, HNRHR was associated with an increased risk of MACCE in patients with OSA (adjusted HR: 1.56, 95% CI: 1.09-2.23, P=0.014), but not in patients without OSA (adjust HR: 1.13, 95% CI: 0.69-1.84, P=0.63). In patients with ACS, a nighttime RHR of ≥ 70 bpm was associated with a higher risk of MACCE in those with OSA but not in those without it. This identifies a potential high-risk subgroup where heart rate may interact with the prognosis of OSA. Further research is needed to determine causative relationships and confirm whether heart rate control impacts cardiovascular outcomes in patients with ACS-OSA.

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.

Perioperative cardiovascular and cerebrovascular outcomes in recipients of ECMO bridge to lung transplant

BackgroundThe use of ECMO as bridge to lung transplant (BTT) has increased over time. While one-year and overall survival have been reported to be similar with non-ECMO transplant recipients, there are limited data major adverse cardiovascular and cerebrovascular events (MACCE) and clinically relevant bleeding (CRB) events. In this study we sought to evaluate the incidence of perioperative MACCE and CRB in lung transplant recipients who underwent ECMO BTT. MethodsUsing the National Inpatient Sample from 2008 to 2019, we identified 5,254 lung transplant recipients who either received or did not require pre-transplant ECMO. Perioperative MACCE and CRB were compared between the two cohorts. ResultsPatients with ECMO BTT had a higher incidence of MACCE compared to non-ECMO patients (35% vs. 13.3%, p <0.0001) and CRB (34.5% vs 12.9%, p <0.0001). Recipients of pre-transplant ECMO for double lung transplant (n=158) were more likely to have perioperative MACCE and CRB as opposed to patients without pre-transplant ECMO (n=3,584) (adjusted odds ratio 2.69, p <0.0001; 95% CI 1.86-3.80). The ECMO BTT cohort were notably younger with less cardiac comorbidities and higher diagnoses of cystic fibrosis and ILD. ConclusionOur data indicate that lung transplant recipients who required ECMO BTT are at significantly higher risk of MACCE and bleeding events despite being younger with less comorbidities as opposed to those who did not require ECMO.

The efficacy of minimally invasive coronary artery bypass grafting (mics cabg) for patients with coronary artery diseases and diabetes: a single center retrospective study

Backgroundconventional coronary artery bypass grafting (CCABG) tends to cause severe complications in patients with comorbid Coronary Artery Diseases (CAD) and diabetes. On the other hand, the Minimally Invasive Cardiac Surgery Coronary Artery Bypass Grafting (MICS CABG) via transthoracic incision is associated with rapid recovery and reduced complications. Adding to the limited literature, this study compares CCABG and MICS CABG in terms of efficacy and safety.MethodsHerein, 104 CCABG and MICS CABG cases (52 cases each) were included. The patients were recruited from the Minimally Invasive Cardiac Surgery Center, Anzhen Hospital, between January 2017 and December 2021 and were selected based on the Propensity Score Matching (PSM) model. The key outcomes included All-cause Death, Myocardial Infarction (MI), Cerebrovascular Events, revascularization, Adverse Wound Healing Events and one-year patency of the graft by coronary CTA.ResultsCompared to CCABG, MICS CABG had longer surgical durations [4.25 (1.50) h vs.4.00 (1.13) h, P = 0.028], but showed a reduced intraoperative blood loss [600.00 (400.00) mL vs.700.00 (300.00) mL, P = 0.032] and a lower secondary incision debridement and suturing rate (5.8% vs.19.2%, P = 0.038). In follow up, no statistically significant differences were found between the two groups in the cumulative Major Adverse Cardiovascular and Cerebrovascular Events (MACCEs) incidence (7.7% vs. 5.9%), all-cause mortality (0 vs. 0), MI incidence (1.9% vs. 2.0%), cerebral apoplexy incidence (5.8% vs. 3.9%), and repeated revascularization incidence (0 vs. 0) (P > 0.05). Additionally, coronary CTA results revealed that the two groups’ one-year graft patency (94.2% vs. 90.2%, P = 0.761) showed no statistically significant difference.ConclusionIn patients with comorbid CAD and diabetes, MICS CABG and CCABG had comparable revascularization performances. Moreover, MICS CABG can effectively reduce, if not prevent, poor clinical outcomes/complications, including incision healing, sternal infection and prolonged length of stay in diabetes patients.

Association of Preprocedural SYNTAX Score With Outcomes in Impella-Assisted High-Risk Percutaneous Coronary Intervention

BackgroundPatients with complex coronary artery disease, as defined by high SYNTAX scores, undergoing percutaneous coronary intervention (PCI) have poorer outcomes when compared with patients with lower SYNTAX I scores. This study aimed to assess if mechanical circulatory support using Impella mitigates the effect of the SYNTAX I score on outcomes after high-risk percutaneous coronary intervention (HRPCI). MethodsUsing data from the PROTECT III study, patients undergoing Impella-assisted HRPCI between March 2017 and March 2020 were divided into 3 cohorts based on SYNTAX I score—low (≤22), intermediate (23-32), and high (≥33). Procedural and clinical outcomes out to 90 days were compared between groups. Multivariable regression analysis was used to assess the impact of SYNTAX I score on major adverse cardiovascular and cerebrovascular events (MACCE) at 90 days. ResultsA total of 850 subjects with core laboratory–adjudicated SYNTAX I scores were identified (low: n = 310; intermediate: n = 256; high: n = 284). Patients with high SYNTAX I scores were older than those with low or intermediate SYNTAX I scores (72.7 vs 69.7 vs 70.1 years, respectively; P < .01). After adjustment for covariates, high SYNTAX I score remained a significant predictor of 90-day MACCE (hazard ratio [HR], 2.14; 95% CI, 1.42-3.69; P < .01 vs low), whereas intermediate SYNTAX I score was not (HR, 0.92; 95% CI, 0.47-1.77; P = .80 vs low). These findings persisted after adjustment for post-PCI SYNTAX I score. ConclusionsA high SYNTAX I score was associated with higher rates of 90-day MACCE in patients who underwent Impella-assisted HRPCI. Further research is needed to understand the patient and procedural factors driving this finding.

Prognostic value of serum immunoglobulin M levels in patients with acute coronary syndrome

Background and aimsThe immuno-inflammatory response is a crucial early step in the development of acute coronary syndrome (ACS). In this study, we investigated whether immunoglobulin M (IgM) in the body's initial immune response can predict the prognosis of patients with ACS. MethodsThis prospective cohort study enrolled 1556 ACS patients at Beijing Hospital between March 2017 and October 2020. All patients underwent coronary angiography (CAG). The serum IgM concentration and biochemical indicators were evaluated prior to CAG. The primary endpoint was the composite endpoint of major adverse cardiovascular and cerebrovascular events (MACCEs). Multivariate Cox proportional hazards models was used to explore the association between IgM levels and the endpoint. ResultsThe average serum IgM levels of the population was 61.3 (42.6–88.4) mg/dL. During the median follow-up period of 55 months, 150 MACCEs occurred. Kaplan-Meier analysis showed that low serum IgM levels were associated with occurrence of MACCEs (log-rank p = 0.009). Univariate Cox proportional hazards models showed that low serum IgM (≤78.05 mg/dL) was associated with MACCEs (hazard ratio (HR) 1.648, 95 % confidence interval (CI): 1.129–2.406, p = 0.010). In patients with IgM ≤78.05 mg/dL, the HR for partially adjusted MACCEs events was 1.576 (95 % CI: 1.075–2.310) and 1.930 (95 % CI: 1.080–3.449) after adjusting for multiple covariates. The subgroup analysis showed that for patients in ≤24 BMI, never smoking and non-dyslipidemia subgroup, the lower serum IgM levels was significantly associated with the risk of MACCEs (pinteraction < 0.001, pinteraction = 0.037, pinteraction = 0.024, respectively). ConclusionsLow serum IgM levels was independently associated with MACCEs in ACS patients, especially for patients without obesity, smoking and dyslipidemia.

Sex-based association between high-density lipoprotein cholesterol and adverse outcomes after coronary artery bypass grafting

BackgroundHigh-density lipoprotein cholesterol (HDL-C) is shown to be an independent protective factor against coronary artery diseases (CAD). Yet there are limited studies focusing on the association between HDL-C and coronary artery bypass graft (CABG) surgery outcomes.HypothesisLow levels of HDL-C are associated with higher incidence of adverse outcomes in patients undergoing CABG.MethodsThis registry-based study included 17,772 patients who underwent elective isolated CABG between 2007 and 2017. Patients were classified into low and desirable HDL-C groups based on their serum HDL-C levels at admission and were followed for one-year post-surgery. The study population included 13,321 patients with low HDL-C and 4,451 with desirable HDL-C. proportional hazard Cox models were performed to evaluate the association between HDL-C levels and incidence of mortality as well as major adverse cardiovascular and cerebrovascular events (MACCE), while adjusting for potential confounders. Moreover, participants were stratified based on sex and the association was also investigated in each subgroup separately.ResultsNo significant difference was found between the groups regarding incidence of both mortality and MACCE, after adjusting with Inverse Probability Weighting (IPW) [HR (95%CI): 0.84 (0.46–1.53), p-value:0.575 and HR (95% CI): 0.91 (0.56–1.50), p-value:0.733, respectively]. According to the sex-based subgroup analysis, no significant association was observed after adjustment with IPW analysis. However, as we examined the association between the interaction of HDL-C levels, sex and cardiovascular outcomes, we found a significant association (HR;1.19 (95%CI: 1.04–1.45); p = 0.030).ConclusionHDL-C level was not associated with either mortality or MACCE during one year after CABG procedure. Sex-based analysis showed that in males, HDL-C is significantly more protective against these outcomes, compared to females. Further studies are necessary to elucidate the exact mechanisms mediating such association.

Triglyceride to high-density lipoprotein cholesterol ratio associated with long-term adverse clinical outcomes in patients deferred revascularization following fractional flow reserve

BackgroundGuidelines on coronary intermediate lesions strongly recommend deferred revascularization after detecting a normal fractional flow reserve (FFR). Researches about triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) on cardiovascular diseases has also been well conducted. However, the association of TG/HDL-C and long-term adverse clinical outcomes remains unknown for patients deferred revascularization following FFR.MethodsThis study retrospectively included 374 coronary artery disease (CAD) patients with non-significant coronary lesions diagnosed by coronary angiography (CAG) and FFR. The main outcome measure was the combination of major adverse cardiovascular and cerebrovascular events (MACCEs). All patients were categorized into three subgroups in terms of TG/HDL-C tertiles (T1 < 0.96, 0.96 ≤ T2 < 1.58, T3 ≥ 1.58). Three different Cox regression models were utilized to reveal the association between TG/HDL-C and prevalence of MACCEs.Results47 MACCEs were recorded throughout a median monitoring period of 6.6 years. The Kaplan-Meier survival curves showed a higher MACCEs rate occurred in the higher TG/HDL-C group (5.6% vs. 12.9% vs. 19.4%, log-rank P < 0.01). After adjustment, patients in T3 suffered a 2.6-fold risk compared to the T1 group (T3 vs. T1: HR 2.55, 95% CI 1.05–6.21, P = 0.038; T2 vs. T1: HR 1.71, 95% CI 0.65–4.49, P = 0.075; P for trend = 0.001). The restricted cubic spline (RCS) analysis demonstrated that the HR for MACCEs rose as TG/HDL-C increased. Both the receiver operating characteristic (ROC) and time-dependent ROC proved the excellent predictive ability of TG/HDL-C.ConclusionThe study illustrates that TG/HDL-C correlates with the risk of MACCEs in CAD patients deferred revascularization following FFR. TG/HDL-C could serve as a dependable predictor of cardiovascular events over the long term in this population.

Real-world performance of indobufen versus aspirin after percutaneous coronary intervention: insights from the ASPIRATION registry

BackgroundIndobufen is widely used in patients with aspirin intolerance in East Asia. The OPTION trial launched by our cardiac center examined the performance of indobufen based dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). However, the vast majority of patients with acute coronary syndrome (ACS) and aspirin intolerance were excluded. We aimed to explore this question in a real-world population.MethodsPatients enrolled in the ASPIRATION registry were grouped according to the DAPT strategy that they received after PCI. The primary endpoints were major adverse cardiovascular and cerebrovascular events (MACCE) and Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding. Propensity score matching (PSM) was adopted for confounder adjustment.ResultsA total of 7135 patients were reviewed. After one-year follow-up, the indobufen group was associated with the same risk of MACCE versus the aspirin group after PSM (6.5% vs. 6.5%, hazard ratio [HR] = 0.99, 95% confidence interval [CI] = 0.65 to 1.52, P = 0.978). However, BARC type 2, 3, or 5 bleeding was significantly reduced (3.0% vs. 11.9%, HR = 0.24, 95% CI = 0.15 to 0.40, P < 0.001). These results were generally consistent across different subgroups including aspirin intolerance, except that indobufen appeared to increase the risk of MACCE in patients with ACS.ConclusionsIndobufen shared the same risk of MACCE but a lower risk of bleeding after PCI versus aspirin from a real-world perspective. Due to the observational nature of the current analysis, future studies are still warranted to further evaluate the efficacy of indobufen based DAPT, especially in patients with ACS.Trial registrationChinese Clinical Trial Register (https://www.chictr.org.cn); Number: ChiCTR2300067274.

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. External validation observed a more AUCs greater than 70%.

Effect of statins on severity of coronary artery lesion and clinical prognosis in patients with coronary heart disease

To investigate the effect of statins on the severity of coronary artery lesion in patients with coronary heart disease, and to analyze the risk factors of clinical prognosis. A retrospective cohort study was conducted. The clinical data of 156 patients with coronary heart disease and completed the second re-examination of coronary CT angiography (CCTA) who were admitted to the department of cardiovascular medicine of Peking University People's Hospital from January 2017 to December 2021 were collected. According to whether they took statins regularly according to the doctor's instructions after being diagnosed with coronary heart disease based on the first CCTA examination, the patients were divided into statin group and non-statin group, and the clinical characteristics of the two groups and the results of the second re-examination of CCTA were compared and analyzed. According to whether the patients had major adverse cardiovascular and cerebrovascular events (MACCE) within 3-5 years after diagnosis of coronary heart disease, the patients were divided into MACCE group and non-MACCE group, and the clinical characteristics of the two groups were compared and analyzed. Multivariate Logistic regression analysis was used to screen the risk factors related to the adverse prognosis (occurrence of MACCE) of patients with coronary heart disease. (1) A total of 156 patients with coronary heart disease were enrolled, including 113 patients (72.44%) in the statin group and 43 patients (27.56%) in the non-statin group. Except for low density lipoprotein (LDL) and serum creatinine (SCr), there was no significant difference in gender, age, body mass index (BMI), basic diseases, smoking history, the first CCTA display of coronary artery lesions and plaque characteristics, the interval between the two CCTA and other laboratory indicators between the two groups. Compared with the non-statin group, the statin group had a significant reduction in the overall increase rate of coronary artery stenosis score (Gensini score) in the CCTA re-examination and the incidence of MACCE [Gensini score increase rate: 25.66% (29/113) vs. 46.51% (20/43), incidence of MACCE: 9.73% (11/113) vs. 30.23% (13/43), both P < 0.05]. (2) Among 156 patients with coronary heart disease, 24 cases (15.38%) experienced MACCE within 3-5 years after diagnosis, while 132 cases (84.62%) did not experience MACCE. The proportion of patients in the MACCE group who regularly took statins after diagnosis was significantly lower than that in the non-MACCE group [45.83% (11/24) vs. 77.27% (102/132), P < 0.01], and D-dimer and glycosylated hemoglobin (HbA1c) were significantly higher than those in the non-MACCE group [D-dimer (μg/L): 148.50 (101.25, 314.75) vs. 88.10 (59.03, 132.12), HbA1c: 6.45% (6.20%, 7.93%) vs. 6.10% (5.81%, 6.92%), both P < 0.05]. Compared with the non-MACCE group, in the first CCTA examination of patients in the MACCE group, the total percentage of atheroma volume (PAV), fibrous-fat PAV, necrotic core PAV and Gensini score were significantly increased [total PAV: 43.05% (29.19%, 60.60%) vs. 24.57% (16.94%, 39.09%), fibrous-fat PAV: 18.61% (8.48%, 26.44%) vs. 6.81% (4.16%, 12.57%), necrotic core PAV: 5.96% (2.98%, 8.71%) vs. 2.29% (1.47%, 4.36%), Gensini score: 30.25 (23.50, 38.30) vs. 19.50 (13.20, 31.10), all P < 0.05]. Multivariate Logistic regression analysis showed that regular use of statins [odds ratio (OR) = 0.282, 95% confidence interval (95%CI) was 0.110-0.727, P = 0.008], D-dimer (OR = 1.011, 95%CI was 1.005-1.017, P < 0.001), necrotic core PAV (OR = 1.323, 95%CI was 1.120-1.563, P = 0.001) and Gensini score (OR = 1.038, 95%CI was 1.004-1.073, P = 0.028) were independent risk factors for MACCE within 3-5 years after diagnosis in patients with coronary heart disease. For patients with coronary heart disease, D-dimer, necrotic core PAV, and Gensini scores should be closely monitored. Statins can effectively alleviate the severity of coronary artery disease and reduce the occurrence of MACCE in patients with coronary artery disease.

Association between neutrophil-to-lymphocyte ratio and outcomes in hospitalized patients with left ventricular thrombus.

Left ventricular thrombus (LVT) is a severe cardiovascular complication occurring in approximately 10% of patients with acute anterior ST-segment elevation myocardial infarction. This study aimed to evaluate the association between neutrophil-to-lymphocyte ratio (NLR) and in-hospital major adverse cardiovascular and cerebrovascular events (MACCE) in patients with LVT. This multicenter retrospective study was conducted between January 2000 and June 2022 in hospitalized patients with LVT. The outcome included in-hospital MACCE. The association between NLR and in-hospital MACCE was measured by odds ratios (ORs). The restricted cubic spline model was used for dose-response analysis. A total of 197 LVT patients from four centers were included for analysis in this study. MACCE occurred in 13.7% (27/197) of the patients. After adjusting for estimated glomerular filtration rate (eGFR), D-dimer, and age, the OR for MACCE comparing first to the third tertile of NLR was 13.93 [95% confidence interval: 2.37-81.77, P = 0.004, P -trend = 0.008]. When further adjusting for etiology and heart failure with reduced ejection fraction (HFrEF), the association remained statistically significant. Spline regression models showed an increasing trend in the incidence of MACCEs with NLR both in crude and adjusted models. Subgroup analyses showed that a high NLR may be correlated with poorer outcomes for LVT patients older than 65 years, or with hypertension, dyslipidemia, low ejection fraction, liver, and renal dysfunctions. In conclusion, these findings suggested that higher NLR may be associated with an increased risk of in-hospital MACCE in patients with LVT.

Prediabetes and major adverse cardiac events after acute coronary syndrome: An overestimated concept.

Unlike diabetes, the effect of prediabetes on outcomes in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI) is not much investigated. We investigated the association between fasting glycemic status and major adverse cardiovascular and cerebrovascular events (MACCE) in patients with ACS undergoing PCI and had mid to long-term follow-up after coronary stenting. Registry-based retrospective cohort study included ACS patients who underwent PCI at the Tehran Heart Center from 2015 to 2021 with a median follow-up of 378 days. Patients were allocated into normoglycemic, prediabetic, and diabetic groups. The primary and secondary outcomes were MACCE and its components, respectively. Unadjusted and adjusted Cox models were used to evaluate the association between glycemic status and outcomes. Among 13 682 patients, 3151 (23%) were prediabetic, and 5834 (42.6%) were diabetic. MACCE risk was significantly higher for diabetic versus normoglycemic (adjusted hazard ratio [aHR]: 1.22, 95% confidence interval [CI]: 1.06-1.41), but nonsignificantly higher for prediabetic versus normoglycemic (aHR: 0.95, 95% CI: 0.78-1.10). All-cause mortality risk was significantly higher in diabetic versus normoglycemic (aHR: 1.42, 95% CI: 1.08-1.86), but nonsignificantly higher for prediabetic versus normoglycemic (aHR: 1.15, 95% CI: 0.84-1.59). Among other components of MACCE, only coronary artery bypass grafting was significantly higher in diabetic patients, and not prediabetic, compared with normoglycemic. Prediabetic ACS patients undergoing PCI, unlike diabetics, are not at increased risk of MACCE and all-cause mortality. While prediabetic patients could be regarded as having the same risk as nondiabetics, careful consideration to provide more intensive pre- and post-PCI care in diabetic patients is mandatory.

Sex Differences in Low-Density Lipoprotein Cholesterol Treatment Among Young Israeli Patients Following Premature Acute Coronary Syndrome.

Introduction: Effective management of dyslipidemias is crucial for reducing morbidity and mortality among patients after acute coronary syndrome (ACS). Sex differences in dyslipidemia management after premature ACS in Israeli patients have not been extensively studied. This study aimed to investigate potential disparities between men and women in managing dyslipidemia, considering current guidelines. Methods: This retrospective cohort study examined patients who were 55 years old or younger and admitted to Meir Medical Center for ACS from January 2018 to February 2019. The study aimed to evaluate the use of lipid-lowering therapy (LLT), measure the achievement of target low-density lipoprotein cholesterol (LDL-C) levels, and analyze the occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) in both male and female patients. Results: The study included a total of 687 participants, of which 23.3% were identified as females. Upon discharge, ∼80% of the patients were prescribed high-intensity statins. After 1 year, it was observed that females had higher levels of LDL-C and lower rates of achieving target LDL-C levels (<70 and 55 mg/dL) as compared with males (45% vs. 54.6% and 30% vs. 42.2%, respectively). The use of non-statin LLT at the 1-year mark was minimal in both groups. Finally, it was found that the occurrence of MACCE was similar between males and females. Conclusion: Sex disparities in dyslipidemia management after a premature ACS were apparent, with females having higher LDL-C levels and lower rates of target achievement. Intervention is necessary to address these disparities and encourage greater use of non-statin LLT.

The impact of dyslipidemia on prognosis of patients after endovascular abdominal aortic aneurysm repair.

Dyslipidemia is common in patients with abdominal aortic aneurysm (AAA). However, there is insufficient research on the impact of dyslipidemia on the postoperative outcomes of patients with AAA after endovascular aortic aneurysm repair (EVAR). This study aimed to determine the impact of dyslipidemia on the prognosis of patients with AAA treated with EVAR. We retrospectively reviewed patients with AAA who underwent EVAR at our hospital between 2010 and 2020. The baseline characteristics and prognoses of patients in the dyslipidemia and non-dyslipidemia groups were analyzed. A total of 641 patients were included; the prevalence of dyslipidemia in patients with AAA was 42.3% (271/641), and the mean follow-up time was 63.37 ± 26.49 months. The prevalence of diabetes (10.0% vs. 15.1%, P = 0.050), peripheral arterial disease (17.3% vs. 25.8%, P = 0.018), and chronic kidney disease (3.0% vs. 6.3%, P = 0.043) was higher in the dyslipidemia group. The three-year all-cause mortality rate after EVAR was 9.98% (64/641), and there was no difference in the incidence of all-cause mortality (10.27% vs. 9.59%, P = 0.778) between the two groups. A total of 36 (5.62%) major adverse cardiovascular and cerebrovascular events (MACCEs) were observed within 3 years and were more common in patients with dyslipidemia (2.97% vs. 9.59%, P < 0.001). The incidence of stent-related complications in all patients was 19.97% (128/641), and there was no difference in the incidence of stent-related complications between the two groups (22.16% vs. 16.97%, P = 0.105); however, the incidence of type I endoleak in the dyslipidemia group was lower than that in the non-dyslipidemia group (9.19% vs. 4.06%, P = 0.012). Cox-regression analysis showed that high level of high-density lipoprotein cholesterol (HDL-C) was the protective factor (HR, 0.203, 95% CI, 0.067-0.616, P = 0.005) for MACCES, but it was the risk factor for type I endoleak (HR, 2.317, 95% CI, 1.202-4.466, P = 0.012). Dyslipidemia did not affect the mortality of patients with AAA who underwent EVAR; however, it may increase the incidence of MACCEs. Dyslipidemia may decrease the incidence of type I endoleaks after EVAR; however, further studies are warranted. We should strengthen the postoperative management of patients with dyslipidemia, prevent the occurrence of MACCEs.

A high level of uric acid is associated with long-term adverse cardiovascular outcomes in patients who received fractional flow reserve with coronary intermediate stenosis

Background and aimsThe role of fractional flow reserve (FFR) in coronary intermediate lesions is widely recommended by guidelines. The effect of uric acid (UA) on cardiovascular events is also well known. However, the relationship between UA and long-term cardiovascular outcomes in patients who received FFR with intermediate lesions remains unknown. Methods and resultsWe retrospectively included 428 patients who underwent both coronary angiography (CAG) and FFR. Participants were stratified into two groups based on the median UA. The primary endpoint was the composite of major adverse cardiovascular and cerebrovascular events (MACCEs), including repeat revascularization, nonfatal stroke, nonfatal myocardial infarction, and all-cause death. A Cox proportional hazards model was utilized to analyze the association between UA and the prevalence of MACCEs. During a median follow-up of 5.8 years, a higher MACCEs rate occurred in the high UA group compared to the low UA group (16.8% vs. 5.1%, p log-rank<0.01). Elevated UA was independently linked to a higher incidence of MACCEs, whether UA was treated as a categorical or continuous variable (hazard ratio [HR] 2.76, 95% confidence interval [CI] 1.27–6.03 or HR 1.01, 95% CI 1.01–1.02). The restricted cubic spline (RCS) analysis illustrated that the HR for MACCEs increased with increasing UA. ConclusionThe present study demonstrates that UA is associated with MACCEs risk and suggests that UA is a reliable predictor of long-term cardiovascular events in coronary intermediate stenosis patients.
