Trends of risk factors in coronary surgery

Introduction. In current era of widespread use of percutaneous coronary interventions (PCI), it is debatable whether coronary artery by-pass graft (CABG) patients are at higher risk. Objective. The aim of the study was to evaluate trends in risk profile of isolated CABG patients. Methods. By analysing the EuroSCORE and its risk factors, we reviewed a consecutive group of 4675 isolated CABG patients, operated on during the last 8 years (2001-2008) at our Clinic. The number of PCI patients was compared to the number of CABG patients. For statistical analyses, Pearson?s chi-square and ANOVA tests were used. Results. The number of PCI increased from 159 to 1595 (p<0.001), and the number of CABG from 557 to 656 (p<0.001). The mean EuroSCORE increased from 2.74 to 2.92 (p=0.06). The frequency of the following risk factors did not change over years: female gender, previous cardiac surgery, serum creatinine >200?mol/l, left ventricular dysfunction and postinfarct ventricular septal rupture. Chronic pulmonary disease, neurological dysfunction, and unstable pectoral angina declined significantly (p<0.001). Critical preoperative care declined from 3.1% in 2001 to 0.5 % in 2005, than increased and during the last 3 years did not change (2.3%). The mean age increased from 56.8 to 60.7 (p<0.001) and extracardiac arteriopathy increased from 9.2% to 22.9% (p<0.001). Recent preoperative myocardial infarction increased from 11% to 15.1% (p=0.021), while emergency operations increased from 0.9% to 4.0% (p=0.001). Conclusion. The number of CABG increases despite the enlargement of PCI. The risk for isolated CABG given by EuroSCORE increases over years. The risk factors, significantly contributing to higher EuroSCORE are: older age, extracardiac arteriopathy, recent myocardial infarction and emergency operation.

Objective: Levosimendan is a novel drug often used to treat heart failure. We aimed to explore the effects of levosimendan preconditioning on left ventricular remodeling (LVR) after myocardial reperfusion in acute myocardial infarction (AMI) patients receiving the percutaneous coronary intervention (PCI). Methods: A total of 258 AMI patients treated from January 2018 to September 2020 were randomly divided into control and observation groups. Based on conventional drug therapy, levosimendan was given 30 min before PCI for the observation group, and dobutamine was intravenously injected for the control group. Baseline data, thrombolysis in myocardial infarction (TIMI) blood flow grade, myocardial injury markers, and LVR indices were compared, and the influencing factors for LVR were analyzed. Results: After treatment, various degrees of blood perfusion were found, and the TIMI grade was better than that before treatment in both groups (P < .05). The levels of aspartate aminotransferase, creatine kinase-MB, cardiac troponin T, and brain natriuretic peptide (BNP) declined in both groups, more significantly in the observation group (P < .05). Left ventricular end-systolic diameter, left ventricular end-diastolic diameter and left ventricular end-diastolic volume declined, whereas left ventricular ejection fraction rose in both groups, more significantly in the observation group (P < .05). Age and BNP were risk factors for LVR, whereas levosimendan preconditioning was a protective factor (P < .05). Conclusion: Levosimendan preconditioning can protect cardiac function and promote the recovery of the left ventricular structure. Age and BNP are risk factors for LVR after myocardial reperfusion in AMI patients undergoing PCI, and levosimendan preconditioning is a protective factor.

Background: Acute myocardial infarction is one of the very common ailments, that quite often ends in mortality. The risk factors for AMI has been identified as smoking, alcoholism, high cholesterol, obesity, left ventricular hypertrophy, high triglyceride levels and diabetes mellitus. This study was done to evaluate diabetes as a risk factor for the incidence of acute myocardial infarction in our area.Methods: Demographic details such as age, sex, height, weight, BMI, blood pressure, details of alcoholism or smoking were taken. Physical examination was conducted for all the patients. Previous clinical and medical history was taken for all the patients. The predictors for calculation of 10 years risk factor for SCORE were age, sex, smoking, cholesterol and triglyceride levels and blood pressure.Results: The mean age of the males was 66.1±2.7 and women was 68.8±4.9. 27.3% of the males and 29.4% of the females were obese while 34.6% of males and 32.4% of females were overweight. The mean random blood sugar among the diabetic patients was around 143.5 mg/dL, and in the non-diabetics it was 84.4mg/dL. Out of the 48 diabetic patients, 32 of them (66.7%) had a previous history of MI while in non-diabetes, 53.7% had a previous MI attack.Conclusions: It is essential for the early detection of diabetes and control of the sugar levels, so as to reduce the risk of cardiovascular ailments, since diabetes is one of the independent risk factors.

Objectives: We evaluated in-hospital and long-term outcomes of patients who underwent primary percutaneous coronary intervention (PCI) in a tertiary center. Patients and Methods: We examined 1550 patients (mean age: 58.5 years, 83.1% male) admitted with acute ST-segment elevation myocardial infarction (AMI) who underwent primary PCI and were followed-up prospectively. The primary outcomes were in-hospital death and major adverse cardiac events (MACE) at follow-up. Results: The mean duration of ischemia at admission was 2.85 ± 2.49 hours; and the mean door-to-device time was 43.2 ± 20.3 minutes. During hospitalization, all-cause mortality occurred in 73 patients (4.7%). Multivariate analysis revealed that advanced age, impaired left ventricular ejection function, high Killip functional class, hemoglobin level at admission, ventricular arrhythmias, and advanced atrioventricular block were independent predictors of poor prognosis (OR: 1.07, 0.93, 15.34, 1.44, 3.79, and 4.26, respectively). Among discharged patients with a median follow-up of 49.5 (25‒73) months, 12.4% experienced all-cause mortality, 12.5% had recurrent myocardial infarction (MI), and 2.3% had a cerebrovascular accident. The strongest independent MACE predictors were impaired left ventricular function, poor glomerular filtration rate, low albumin level, and a history of cerebrovascular disease (HR: 0.97, 0.99, 0.65, and 2.50, respectively). Secondary outcomes were contrast-induced acute kidney injury (16.7%), ventricular arrhythmias (6.1%), advanced atrioventricular block (3.7%), atrial fibrillation (7.6%), and major bleeding (1.6%). Conclusion: AMI still has a poor long-term prognosis. These results emphasize the advantages of rapid, non-delayed revascularization. Patients should be followed-up closely after discharge in both the short- and long-term.

BACKGROUND Coronary microvascular obstruction /no-reflow(CMVO/NR) is a predictor of long-term mortality in survivors of ST elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (PPCI). OBJECTIVE To identify risk factors of CMVO/NR. METHODS Totally 2384 STEMI patients treated with PPCI were divided into two groups according to thrombolysis in myocardial infarction(TIMI) flow grade:CMVO/NR group(246cases,TIMI 0-2 grade) and control group(2138 cases,TIMI 3 grade). We used univariable and multivariable logistic regression to identify risk factors of CMVO/NR. RESULTS A frequency of CMVO/NR was 10.3%(246/2384). Logistic regression analysis showed that the differences between the two groups in age(unadjusted odds ratios [OR] 1.032; 95% CI, 1.02 to 1.045; adjusted OR 1.032; 95% CI, 1.02 to 1.046 ; P <0.001), periprocedural bradycardia (unadjusted OR 2.357 ; 95% CI, 1.752 to 3.171; adjusted OR1.818; 95% CI, 1.338 to 2.471 ; P <0.001),using thrombus aspirationdevices during operation (unadjusted OR 2.489 ; 95% CI, 1.815 to 3.414; adjusted OR1.835; 95% CI, 1.291 to 2.606 ; P =0.001),neutrophil percentage (unadjusted OR 1.028 ; 95% CI, 1.014 to 1.042; adjusted OR1.022; 95% CI, 1.008 to 1.036 ; P =0.002) , and completely block of culprit vessel (unadjusted OR 2.626; 95% CI, 1.85 to 3.728; adjusted-OR 1.656;95% CI, 1.119 to 2.45; P =0.012) were statistically significant ( P <0. 05). The area under the receiver operating characteristic curve was 0.6896 . CONCLUSIONS Age , periprocedural bradycardia, using thrombus aspirationdevices during operation, neutrophil percentage ,and completely block of culprit vessel may be independent risk factors for predicting CMVO/NR.

Abstract Background Left ventricular dysfunction after an acute myocardial infarction (MI) is associated with poor outcome. The PARADISE-MI trial is examining whether an angiotensin receptor-neprilysin inhibitor reduces the risk of cardiovascular death or worsening heart failure (HF) in this population. The aim of this study was to examine the prevalence and prognosis of different subsets of post-MI patients in a real-world setting. Additionally, the prognostic importance of some common risk factors used as risk enrichment criteria in the PARADISE-MI trial were specifically examined. Methods In a nationwide myocardial infarction registry (SWEDEHEART), including 87 177 patients with type 1 MI between 2011–2018, 3 subsets of patients were identified in the overall MI cohort (where patients with previous HF were excluded); population 1 (n=27 568 (32%)) with signs of acute HF or an ejection fraction (EF) <50%, population 2 (n=13 038 (15%)) with signs of acute HF or an EF <40%, and population 3 (PARADISE-MI like) (n=11 175 (13%)) with signs of acute HF or an EF <40% and at least one risk factor (Age ≥70, eGFR <60, diabetes mellitus, prior MI, atrial fibrillation, EF <30%, Killip III-IV and STEMI without reperfusion therapy). Results When all MIs, population 1 (HF or EF <50%), 2 (HF or EF <40%) and 3 (HF or EF <40% + additional risk factor (PARADISE-MI like)) were compared, the median (IQR) age increased from 70 (61–79) to 77 (70–84). Also, the proportion of diabetes (22% to 33%), STEMI (38% to 50%), atrial fibrillation (10% to 24%) and Killip-class >2 (1% to 7%) increased. After 3 years of follow-up, the cumulative probability of death or readmission because of heart failure in the overall MI population and in population 1 to 3 was 17.4%, 26.9%, 37.6% and 41.8%, respectively. In population 2, all risk factors were independently associated with death or readmission because of HF (Age ≥70 (HR (95% CI): 1.80 (1.66–1.95)), eGFR <60 (1.62 (1.52–1.74)), diabetes mellitus (1.35 (1.26–1.44)), prior MI (1.16 (1.07–1.25)), atrial fibrillation (1.35 (1.26–1.45)), EF <30% (1.69 (1.58–1.81)), Killip III-IV (1.34 (1.19–1.51)) and STEMI without reperfusion therapy (1.34 (1.21–1.48))) in a multivariable Cox regression analysis. The risk increased with increasing number of risk factors (Figure 1). Conclusion Depending on definition, post MI HF is present in 13–32% of all MI patients and is associated with a high risk of subsequent death or readmission because of HF. The risk increases significantly with every additional risk factor. There is a need to optimize management and improve outcomes for this high risk population.

IntroductionDelirium in the postoperative period is a wide-reaching problem that affects important clinical outcomes. The incidence and risk factors of delirium in individuals with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PCI) has not been completely determined and no relevant systematic review and meta-analysis of incidence or risk factors exists. Hence, we aim to conduct a systematic review and meta-analysis to ascertain the incidence and risk factors of delirium among AMI patients undergoing PCI.Methods and analysesWe will undertake a comprehensive literature search among PubMed, EMBASE, Cochrane Library, PsycINFO, CINAHL and Google Scholar from their inception to the search date. Prospective cohort and cross-sectional studies that described the incidence or at least one risk factor of delirium will be eligible for inclusion. The primary outcome will be the incidence of postoperative delirium. The quality of included studies will be assessed using a risk of bias tool for prevalence studies and the Cochrane guidelines. Heterogeneity of the estimates across studies will be assessed. Incidence and risk factors associated with delirium will be extracted. Incidence data will be pooled. Each risk factor reported in the included studies will be recorded together with its statistical significance; narrative and meta-analytical approaches will be employed. The systematic review and meta-analysis will be presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.Ethics and disseminationThis proposed systematic review and meta-analysis is based on published data, and thus there is no requirement for ethics approval. The study will provide an up to date and accurate incidence and risk factors of delirium after PCI among patients with AMI, which is necessary for future research in this area. The findings of this study will be disseminated through publication in a peer-reviewed journal.PROSPERO registration numberCRD42020184388.

(1) Background: The effects of exercise-based cardiac rehabilitation (CR) on left ventricular function in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) are important but poorly understood. (2) Purpose: To evaluate the effects of an exercise-based CR program (exercise training alone or combined with psychosocial or educational interventions) compared with usual care on left ventricular function in patients with AMI receiving PCI. (3) Data sources, study selection and data extraction: We searched PubMed, WEB OF SCIENCE, EMBASE, EBSCO, PsycINFO, LILACS and Cochrane Central Register of Controlled Trials databases (CENTRAL) up to 12th June 2021. Article selected were randomized controlled trials and published as a full-text article. Meta-analysis was conducted with the use of the software Review manager 5.4. (4) Data synthesis: Eight trials were included in the meta-analysis, of which three trials were rated as high risk of bias. A significant improvement was seen in the exercise-based CR group compared with the control group regarding left ventricular ejection fraction (LVEF) (std. mean difference = 1.33; 95% CI:0.43 to 2.23; p = 0.004), left ventricular end-diastolic dimension (LVEDD) (std. mean difference = −3.05; 95% CI: −6.00 to −0.09; p = 0.04) and left ventricular end-systolic volume (LVESV) (std. mean difference = −0.40; 95% CI: −0.80 to −0.01; p = 0.04). Although exercise-based CR had no statistical effect in decreasing left ventricular end-systolic dimension (LVESD) and left ventricular end-diastolic volume (LVEDV), it showed a favorable trend in relation to both. (5) Conclusions: Exercise-based CR has beneficial effects on LV function and remodeling in AMI patients treated by PCI.

Aims To investigate the different risk factors among different subtypes of patients with acute coronary syndrome (ACS). Methods A total of 296 patients who had ACS were retrospectively enrolled. Blood and echocardiographic indices were assessed within 24 hours after admission. Differences in risk factors and Gensini scores of coronary lesions among three groups were analyzed. Results Univariate analysis of risk factors for ACS subtypes showed that age, and levels of fasting plasma glucose, amino-terminal pro-brain natriuretic peptide, and creatine kinase isoenzyme were significantly higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than in those with unstable angina pectoris (UAP). Logistic multivariate regression analysis showed that amino-terminal pro-brain natriuretic peptide and the left ventricular ejection fraction (LVEF) were related to ACS subtypes. The left ventricular end-diastolic diameter was an independent risk factor for UAP and ST-segment elevation myocardial infarction (STEMI) subtypes. The severity of coronary stenosis was significantly higher in NSTEMI and STEMI than in UAP. Gensini scores in the STEMI group were positively correlated with D-dimer levels (r = 0.429) and negatively correlated with the LVEF (r = −0.602). Conclusion Different subtypes of ACS have different risk factors. Our findings may have important guiding significance for ACS subtype risk assessment and clinical treatment.
