Prognostic value of novel atherogenic indices in patients with acute myocardial infarction with and without type 2 diabetes

AimsAtherogenic indices: Triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, Atherogenic Index of Plasma (AIP), Atherogenic Coefficient (AC), Castelli's Risk Index I and II (CRI-I, CRI-II) are used in clinical studies as surrogates of major adverse cardiac and cerebrovascular events (MACCE). Risk prediction of MACCE in patients with acute myocardial infarction (AMI) has vital role in clinical practice. We aimed to assess prognostic value of these indices following AMI. MethodsWe analyzed patients with AMI with and without T2DM and the prognostic values of atherogenic indices for in-hospital death and MACCE within 12 months after AMI. ResultsOf 2461 patients, 152 in-hospital deaths (6.2 %) were reported (74 patients [7.4 %] with T2DM and 78 [5.3 %] without T2DM; p = 0.042). MACCE occurred in 22.7 % of patients (29.7 % with T2DM and 17.9 % without T2DM; p < 0.001). TG/HDL-C and AIP were higher in T2DM patients compared to those without T2DM (p < 0.001). Long-term MACCE was more prevalent in patients with T2DM (p < 0.001). The AUC-ROC for predicting in-hospital death based on TG/HDL-C and AIP was 0.57 (p = 0.002). ConclusionsNone of the atherogenic indices was an independent risk factor for in-hospital death or MACCE at 12-month follow-up in patients with AMI. AIP was an independent risk factor for death at 12-month follow-up.

Coronary sodium [18F]fluoride activity predicts outcomes post-CABG: a comparative evaluation with conventional metrics.

The value of preoperative multidisciplinary approach remains inadequately delineated in forecasting postoperative outcomes of patients undergoing coronary artery bypass grafting (CABG). Herein, we aimed to ascertain the efficacy of multi-modality cardiac imaging in predicting post-CABG cardiovascular outcomes. Patients with triple coronary artery disease underwent cardiac sodium [18F]fluoride ([18F]NaF) positron emission tomography/computed tomography (PET/CT), coronary angiography, and CT-based coronary artery calcium scoring before CABG. The maximum coronary [18F]NaF activity (target-to-blood ratio [TBR]max) and the global coronary [18F]NaF activity (TBRglobal) was determined. The primary endpoint was perioperative myocardial infarction (PMI) within 7-day post-CABG. Secondary endpoint included major adverse cardiac and cerebrovascular events (MACCEs) and recurrent angina. This prospective observational study examined 101 patients for a median of 40 months (interquartile range: 19-47 months). Both TBRmax (odds ratio [OR] = 1.445; p = 0.011) and TBRglobal (OR = 1.797; P = 0.018) were significant predictors of PMI. TBRmax>3.0 (area under the curve [AUC], 0.65; sensitivity, 75.0%; specificity, 56.8%; p = 0.036) increased PMI risk by 3.661-fold, independent of external confounders. Kaplan-Meier test revealed a decrease in MACCE survival rate concomitant with an escalating TBRmax. TBRmax>3.6 (AUC, 0.70; sensitivity, 76.9%; specificity, 73.9%; p = 0.017) increased MACCEs risk by 5.520-fold. Both TBRmax (hazard ratio [HR], 1.298; p = 0.004) and TBRglobal (HR = 1.335; p = 0.011) were significantly correlated with recurrent angina. No significant associations were found between CAC and SYNTAX scores and between PMI occurrence and long-term MACCEs. Quantification of coronary microcalcification activity via [18F]NaF PET displayed a strong ability to predict early and long-term post-CABG cardiovascular outcomes, thereby outperforming conventional metrics of coronary macrocalcification burden and stenosis severity. The trial was registered with the Chinese Clinical Trial Committee (number: ChiCTR1900022527; URL: www.chictr.org.cn/showproj.html?proj=37933 ).

The prognostic impact of insulin resistance surrogates in patients with acute myocardial infarction with and without type 2 diabetes.

Cardiovascular disease is the major cause of morbidity and mortality, particularly in type 2 diabetes mellitus (T2DM). Novel markers of insulin resistance and progression of atherosclerosis include the triglycerides and glucose index (TyG index), the triglycerides and body mass index (Tyg-BMI) and the metabolic score for insulin resistance (METS-IR). Establishing independent risk factors for in-hospital death and major adverse cardiac and cerebrovascular events (MACCE) in patients with myocardial infarction (MI) remains critical. The aim of the study was to assess the risk of in-hospital death and MACCE within 12months after ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) in patients with and without T2DM based on TyG index, Tyg-BMI and METS-IR. Retrospective analysis included 1706 patients with STEMI and NSTEMI hospitalized between 2013 and 2021. We analyzed prognostic value of TyG index, Tyg-BMI and METS-IR for in-hospital death and MACCE as its components (death from any cause, MI, stroke, revascularization) within 12months after STEMI or NSTEMI in patients with and without T2DM. Of 1706 patients, 58 in-hospital deaths were reported (29 patients [4.3%] in the group with T2DM and 29 patients [2.8%] in the group without T2DM; p = 0.1). MACCE occurred in 18.9% of the total study population (25.8% in the group with T2DM and 14.4% in the group without T2DM; p < 0.001). TyG index, Tyg-BMI and METS-IR were significantly higher in the group of patients with T2DM compared to those without T2DM (p < 0.001). Long-term MACCE were more prevalent in patients with T2DM (p < 0.001). The area under the ROC curve (AUC-ROC) for the prediction of in-hospital death and the TyG index was 0.69 (p < 0.001). The ROC curve for predicting in-hospital death based on METS-IR was 0.682 (p < 0.001). The AUC-ROC values for MACCE prediction based on the TyG index and METS-IR were 0.582 (p < 0.001) and 0.57 (p < 0.001), respectively. TyG index was an independent risk factor for in-hospital death in patients with STEMI or NSTEMI. TyG index, TyG-BMI and METS-IR were not independent risk factors for MACCE at 12month follow-up. TyG index and METS-IR have low predictive value in predicting MACCE within 12months after STEMI and NSTEMI.

Mid- and Long-Term Surgical Outcomes Due to Infective Endocarditis in Elderly Patients: A Retrospective Cohort Study.

Infective endocarditis (IE) is one of the true remaining dreaded situations in cardiovascular medicine. Current international guidelines do not include specific recommendations for treatment options of infective endocarditis (conventional vs. surgical) based on the patient's age, functional status or comorbidities. Elderly patients have less invasive and often delayed surgeries compared to younger patients due to their shorter long-term survival probabilities. In the setting of IE, this might not be the right treatment, as surgery is the only curative option in up to 50% of all endocarditis patients. The aim of our study was to evaluate the mid- and long-term surgical outcomes due to infective endocarditis of patients aged ≥70 years. Between 2002 and 2020, a retrospective study with 137 patients aged 70 years and older and 276 patients aged below 70 years was conducted. Altogether, 413 consecutive patients who received surgery due to infective native or prosthetic valve endocarditis were assigned to either the elderly (E)-Group or the control (C)-Group. Primary endpoints were short- and long-term MACCEs (Major Adverse Cardiac and Cerebrovascular Events) as a composite of death or major adverse events, and secondary endpoints were intraoperative variables and postoperative course. Preoperative risk factors differed significantly. Elderly patients had more arterial hypertension, atrial fibrillation, diabetes, chronic renal insufficiency and coronary heart disease. Fewer of them were in a state of emergency. Time from diagnosis to OR, antibiotic pretreatment, length of surgery and cardiopulmonary bypass time were significantly longer in the E-Group. Furthermore, 44.5% of patients in the E-Group had prosthesis endocarditis as opposed to 29.7% in the C-group. During postoperative follow-up, new onset of hemodialysis, duration of ventilation, delirium, reintubation and tracheotomy rates were significantly higher in the E-Group. There were significant differences in 7- and 30-day mortality. One- year survival was 62% for the E-Group and 79% for the C-Group. Five-year survival was 47% for the E-Group and 67% for the C-Group. This study demonstrates that surgery for infective endocarditis is a high-risk procedure, especially for elderly people. Nevertheless, as it is more or less the only concept to increase long-term survival, it should be offered generously to all patients who are still able to take care of themselves.

Predictive Factors for Major Adverse Cardiac and Cerebrovascular Events in Octogenarians after Elective Endovascular Aneurysm Repair

The aim of this study was to identify risk factors of major adverse cardiac and cerebrovascular events (MACCEs) in octogenarians who received elective endovascular aneurysm repair (EVAR). Consecutive patients aged ≥ 80years undergoing elective EVAR from 2009 to 2020 were retrospectively evaluated. The primary outcome was long-term MACCE. All independent risk factors for outcomes were determined by multivariate logistic analysis or Cox regression analysis. A total of 163 patients were enrolled in this study. The median age was 81 (interquartile range, 80-84) years and 85.9% (140/163) of them were male. MACCE happened in 2.5% (4/163) patients within 30days. With median follow-up of 28 (interquartile range, 15-46) months, the incidence of long-term MACCE was 26.4% (43/163). Arrhythmia was significantly associated with long-term MACCE (hazard ratio [HR],=2.64; 95% confidence interval [CI], 1.16-6.03, P=0.021). Carotid artery disease was found significantly associated with 2-year MACCE (odds ratio [OR],=6.50, 95% CI, 1.07-39.51, P=0.042). Besides, we found that arrhythmia and congestive heart failure (CHF) were predictors for overall survival (arrhythmia, HR=2.56, 95% CI, 1.05-6.28, P=0.039; CHF, HR=8.96, 95% CI, 2.12-37.79, P=0.003). EVAR in octogenarians had an acceptable perioperative risk and long-term outcome. Considering high risk of 2-year MACCE, intervention strategy should be more cautious for patients with carotid artery disease. Octogenarians with arrhythmia and CHF should receive stricter postoperative management in case of MACCE.

Association Between Nutritional Indices and Long-Term Outcomes in Patients Undergoing Isolated Coronary Artery Bypass Grafting.

BackgroundIt is well known that approximately 20% of patients who undergo cardiac surgery experience weight loss in postoperative period. However, there is a lack of data on postoperative consequences of malnutrition. This study aimed to investigate the relationship between nutritional status and long-term outcomes in patients undergoing isolated coronary artery bypass grafting (CABG).Material and methodsA total of 586 patients who underwent isolated CABG in our center between January 2015 and March 2016 were included in this study. The primary outcome was major adverse cardiac and cerebrovascular events (MACCE) defined as a composite of all-cause death, non-fatal myocardial infarction (MI), and stroke. Patients were divided into two groups based on their MACCE outcomes. Prognostic nutritional index (PNI), geriatric nutritional risk index (GNRI), and controlling nutritional status (CONUT) scores were used to show the nutritional status.ResultsThe mean follow-up time of the whole study group was 38.08 ± 13.4 months. The follow-up time was 39 ± 13 months in patients with mortality, while it was 20 ± 15 months in those without mortality. The PNI and GNRI values were lower in patients with major adverse cardiac and cerebrovascular events (MACCE) compared to patients without MACCE. The median CONUT score was higher in patients with MACCE.ConclusionOur study showed that nutritional indices including PNI, CONUT, and GNRI were associated with long-term MACCE and mortality in patients who underwent isolated CABG. The use of these scores in order to predict prognosis in patients treated with CABG seems to be an applicable method in clinical practice.

Frailty as a predictor of major adverse cardiac and cerebrovascular events after endovascular aortic aneurysm repair

ObjectiveTo evaluate the effect of frailty assessed by the modified Frailty Index (mFI) on major adverse cardiac and cerebrovascular events (MACCE) in the elderly patients after endovascular aortic aneurysm repair (EVAR). MethodsThis was a retrospective cohort study of elderly patients who underwent EVAR in a tertiary hospital. The main exposure was frailty status assessed by the mFI. The primary outcomes were 30-day and long-term MACCE. The predictive ability of the mFI was compared with the Revised Cardiac Risk Index (RCRI) using net reclassification improvement (NRI) and integrated discrimination improvement (IDI) statistics. ResultsOf 749 participants, 134 (17.89%) were identified as frail and 185 (24.70%) as prefrail. Thirteen patients (1.74%) were lost in follow-up after surgery, and the median length of follow-up was 32.00 months (range, 15.00-59.25 months). Frailty was associated with a significantly increased risk of 30-day MACCE (adjusted odds ratio OR, 14.53; 95% confidence interval [CI], 4.59-46.04; P < .0001) and longer intensive care unit stay (adjusted odds ratio, 2.43; 95% CI, 1.17-5.07; P = .0176). As for long-term outcomes, both frailty and prefrailty were associated significantly increased risks of MACCE after EVAR (prefrail: adjusted hazard ratio [HR] 1.71; 95% CI, 1.12-2.61; frail: adjusted HR, 3.37; 95% CI, 1.86-6.10). When considering death as a competing risk, we also observed a significant association between frailty and cardiac and cerebrovascular events (adjusted HR, 2.95; 95% CI, 1.06-8.15). In addition, frailty was associated with a significantly increased risk of all-cause mortality (adjusted HR, 1.93; 95% CI, 1.28-2.90). Compared with the RCRI, the mFI had better discrimination in predicting 30-day MACCE (IDI: 0.225; 95% CI, 0.018-0.431; P = .033; NRI: 0.225; 95% CI, 0.023-0.427; P = .029) and long-term MACCE (IDI: 0.056; 95% CI, 0.018-0.128; P = .013; NRI: 0.237; 95% CI, 0.136-0.359; P < .001). ConclusionsFrailty assessed by the mFI may serve as a useful predictor of both short-term and long-term MACCE in elderly patients after EVAR, with improved discrimination and reclassification abilities compared with the RCRI.

Reoperation for bleeding following coronary artery bypass surgery with special focus on long-term outcomes

Objectives: We studied the incidence and risk factors of reoperation for bleeding following CABG in a nationwide cohort with focus on long-term complications and survival. Design: A retrospective study on 2060 consecutive, isolated CABG patients operated 2001–2016. Outcome of reoperated patients (n = 130) were compared to non-reoperated ones (n = 1930), including major adverse cardiac and cerebrovascular events (MACCE) and overall survival. Risk factors for reoperation were determined using multivariate logistic regression and a Cox proportional hazards model to assess prognostic factors of long-term survival. Median follow-up was 7.6 years. Results: One hundred thirty patients (6.3%) were reoperated with an annual decrease of 4.1% per year over the study period (p=.04). Major complications (18.5 vs. 9.6%) and 30-day mortality (8.5 vs. 1.9%,) were higher in the reoperation group (p<.001). The use of clopidogrel preoperatively (OR 3.62, 95% CI: 1.90–6.57) and reduced left ventricular ejection fraction (OR 2.23, 95% CI: 1.25–3.77) were the strongest predictors of reoperation, whereas off-pump surgery was associated with a lower reoperation risk (OR 0.44, 95% CI: 0.22–0.85). After exluding patients that died within 30 days postoperatively, no difference in long-term survival or freedom from MACCE was found between groups, and reoperation was not an independent risk factor for long-term mortality in multivariate analysis. Conclusions: The reoperation rate in this study was relatively high but decreased significantly over time. Reoperation was associated with twofold increased risk for major complications and fourfold 30-day mortality, but comparable long-term MACCE and survival rates. This implies that if patients survive the first 30 days following reoperation, their long-term outcome is comparable to non-reoperated patients.

Association of lymphocyte-to-monocyte ratio with in-hospital and long-term major adverse cardiac and cerebrovascular events in patients with ST-elevated myocardial infarction.

In recent years, lymphocyte-to-monocyte ratio (LMR) has become a novel indirect marker of inflammation, which has been demonstrated to be associated with poor prognosis of oncology and cardiovascular disease. The aim of the study was to assess the relationship between LMR on admission and in-hospital and long-term major adverse cardiac and cerebrovascular events (MACCE) in patients with ST-elevated myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI).A total of 306 STEMI patients were enrolled and grouped according to tertiles of LMR from the blood samples obtained in the emergency room on admission. Total white blood cell count, differential count of neutrophil, lymphocyte, monocyte, and other factors were evaluated.The median follow-up period was 21 months (1–36 months). As the LMR decreased, in-hospital nonfatal myocardial infarction and cardiovascular mortality increased (P = .002, P = .009, respectively). And long-term stroke/TIA, TVR, nonfatal myocardial infarction, and cardiovascular mortality also increased with decreasing LMR (P = .012, P = .001, P = .003, P = .002, respectively). The receiver operating characteristic (ROC) curve of LMR for predicting MACCE showed the sensitivity of 76% and specificity of 78% and the optimal cut-off value was determined as 2.62. In multivariate analysis, after adjusting for confounders, LMR was an independent predictor of in-hospital and long-term MACCE (odds ratio [OR] 1.192 [1.069–1.315] P < .001, OR 1.239 [1.125–1.347] P < .001, respectively).The LMR is an independent predictor of in-hospital and long-term MACCE in patients with STEMI after primary PCI. Our results suggest that this simple, inexpensive, relatively available inflammatory marker may have significant effects on the treatment and prognosis in patients with STEMI.

The SYNTAX score is correlated with long-term outcomes of coronary artery bypass grafting for complex coronary artery lesions.

We analysed retrospectively the long-term outcomes of conventional coronary artery bypass grafting (CABG) as employed routinely for complex coronary lesions by observing patients with low (0-22), intermediate (23-32) and high (≥33) SYNTAX scores. The purpose of this study was to evaluate the correlation between the SYNTAX score and long-term major adverse cardiac and cerebrovascular events (MACCEs) including all-cause death, stroke, myocardial infarction (MI) and repeat revascularization after CABG. The study enrolled 396 consecutive patients with stable and untreated left main and/or three-vessel disease, who had been referred to our heart team from 2000 through 2009. They all routinely underwent conventional CABG. The three groups (low score; n = 159, intermediate score; n = 150, high score; n = 87) were compared, looking at the primary endpoint of MACCE and its components. We also analysed the effects of diverse variables on long-term MACCEs after the operation. The cumulative 10-year MACCE rates in patients with low, intermediate and high SYNTAX score were 25.3, 35.8 and 48.1%, respectively. The Kaplan-Meier cumulative event curves showed a significantly higher MACCE rate after CABG in patients with a higher SYNTAX score than in those with a lower score (log-rank P = 0.0012). This was mainly because of a significantly increased rate of repeat revascularization in the higher SYNTAX score group (log-rank P = 0.0032). The cumulative rate of repeat revascularization at 10 years in patients having low, intermediate and high SYNTAX score were, respectively, 4.6, 15.7 and 16.8%. The cumulative rates of the combined outcomes of death/stroke/MI at 10 years did not show statistical differences between the three groups (22.3% with low, 25.0% with intermediate and 38.4% with high score, log-rank P = 0.063). In the multivariable analysis, the SYNTAX score [hazard ratio (HR) 1.03, P = 0.0043] and logistic EuroSCORE II (HR 1.34, P = 0.0012) were found to be significant predictors of long-term MACCEs. The SYNTAX score is correlated with long-term outcomes, in terms of MACCEs, after conventional CABG for complex coronary lesions and is prognostic of long-term outcomes of CABG for patients with complex lesions.
