Background: A subgroup of patients with acute kidney injury (AKI) do not fulfil the functional criteria for AKI diagnosis but show elevated levels of new biomarkers reflecting tubular injury, suggesting that these patients suffer “subclinical AKI”. We investigated the incidence and possible implications of “subclinical AKI”, compared to no and clinical AKI among ST elevation myocardial infarction patients (STEMI) treated with primary coronary intervention (PCI). Methods: We included 223 patients with STEMI treated with PCI. Neutrophil gelatinase-associated lipocalin (NGAL) was used as a marker of renal tubular damage in the absence of functional AKI, with NGAL levels ≥100 ng/mL suggesting subclinical AKI. Patients were assessed for the occurrence of in-hospital adverse outcomes. Results: Of the study patients, 45 (25%) had subclinical AKI. These patients were more likely to have left ventricular ejection fraction ≤45% (33% vs. 23%. p = 0.01), in-hospital adverse outcomes (73% vs. 48%; p = 0.005), and a combination of the two. The multivariate regression model demonstrated that subclinical AKI was independently associated with in-hospital adverse outcomes (OR 3.71, 95% CI 1.30–10.62, p = 0.02). Conclusions: Subclinical AKI is common among STEMI patients and is independently associated with adverse outcomes, even in the absence of functional AKI.

Background: Neutrophil gelatinase-associated lipocalin (NGAL) is an early marker of renal tubular damage. We investigated the incidence and possible implications of elevated NGAL levels (suggesting renal damage) compared to both functional and damage markers (manifested as serum creatinine [sCr] elevation) and no NGAL/sCr change, among ­ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI). Methods: We included 131 patients with STEMI treated with PCI. Blood samples for plasma NGAL were drawn 24 h following PCI. We used the terms NGAL(–) or NGAL(+) with levels ≥100 ng/mL suggesting renal tubular damage and the terms. sCr(–) or sCr(+) to consensus diagnostic increases in sCr defining acute kidney injury. Patients were also assessed for in hospital-adverse outcomes. Results: Of the study patients, 56 (42%) were NGAL(–)/sCr(–), 58 (44%) NGAL(+)/sCr(–), and 18 (14%) were both NGAL(+)/sCr(+). According to the 3 study groups, there was a stepwise increase in the proportion of left ventricular ejection fraction ≤45% (43 vs. 60. vs. 72%; p = 0.04), in-hospital adverse outcomes (9 vs. 14 vs. 56%; p < 0.001) and their combination. Specifically, more NGAL(+)/sCr(–) patients developed the composite endpoint when compared to NGAL(–)/sCr(–) patients (64 vs. 46%; OR 2.1, [95% CI 1.1–4.5], p = 0.05). A similar and consistent increase was observed in peak sCr, length of hospital stay, and C-reactive protein levels. Conclusions: Elevated NGAL levels suggesting renal tubular damage, increased inflammation, or both are common among STEMI patients and are associated with adverse outcomes even in the absence of diagnostic increase in sCr.

de Winter syndrome, also termed anterior ST-segment elevation myocardial infarction (STEMI) equivalent, is estimated to be present in approximately 2% of patients with acute myocardial infarction, but is often under-recognized by clinicians. Therefore, de Winter syndrome is associated with increased morbidity and mortality. We report a 51-year-old man with typical chest tightness and a characteristic electrocardiographic pattern without classic ST-segment elevation, but with acute nearly total occlusion of the left anterior descending coronary artery. Although the patient presented as a non-STEMI case, the definite diagnosis of de Winter syndrome was made on the basis of clinical and electrocardiographic findings. The patient’s symptom of chest tightness was relieved immediately after acute percutaneous coronary intervention and the left ventricular ejection fraction had not deteriorated at 1 month of follow-up.

Abstract Background Left ventricular negative remodelling after ST-segment elevation myocardial infarction (STEMI) is considered as the major cause for the poor prognosis. But the predisposing factors and potential mechanisms of left ventricular negative remodelling after STEMI remain not fully understood. The present research mainly assessed the association between the stress hyperglycaemia ratio (SHR) and left ventricular negative remodelling. Methods We recruited 127 first-time, anterior, and acute STEMI patients in the present study. All enrolled patients were divided into 2 subgroups equally according to the median value of SHR level (1.191). Echocardiography was conducted within 24 h after admission and 6 months post-STEMI to measure left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD). Changes in echocardiography parameters (δLVEF, δLVEDD, δLVESD) were calculated as LVEF, LVEDD, and LVESD at 6 months after infarction minus baseline LVEF, LVEDD and LVESD, respectively. Results In the present study, the mean SHR was 1.22 ± 0.25 and there was significant difference in SHR between the 2 subgroups (1.05 (0.95, 1.11) vs 1.39 (1.28, 1.50), p < 0.0001). The global LVEF at 6 months post-STEMI was significantly higher in the low SHR group than the high SHR group (59.37 ± 7.33 vs 54.03 ± 9.64, p  = 0.001). Additionally, the global LVEDD (49.84 ± 5.10 vs 51.81 ± 5.60, p  = 0.040) and LVESD (33.27 ± 5.03 vs 35.38 ± 6.05, p  = 0.035) at 6 months after STEMI were lower in the low SHR group. Most importantly, after adjusting through multivariable linear regression analysis, SHR remained associated with δLVEF (beta = −9.825, 95% CI −15.168 to −4.481, p  < 0.0001), δLVEDD (beta = 4.879, 95% CI 1.725 to 8.069, p  = 0.003), and δLVESD (beta = 5.079, 95% CI 1.421 to 8.738, p  = 0.007). Conclusions In the present research, we demonstrated for the first time that SHR is significantly correlated with left ventricular negative remodelling after STEMI.

Abstract Objective To investigate the correlation between Procollagen I C-Terminal Propeptide (PICP), Procollagen III N-Terminal Propeptide (PIIINP), indices of echocardiography and anamnestic data in patients with ST segment elevation myocardial infarction (STEMI) and preserved myocardial contractility. Materials and methods 60 men and 23 women diagnosed with STEMI were examined. Echocardiographic studies were performed using SONOS 2500 Cardiac – Vascular Ultrasound (Hewlett Packard, USA). Myocardial contractility was considered to be preserved with left ventricular ejection fraction (LVEF) ≥50%. In addition to standard indices of echocardiography, mitral flow propagation velocity (FPV) was evaluated to diagnose diastolic dysfunction. Coronary angiography was performed using INNOVA 3100 Cardiovascular Imaging System (USA). All patients, during the first twelve hours of the disease, underwent percutaneous coronary intervention (PCI) with stenting of the occluded culprit infarct-related artery. On the 1st and 12th days of hospitalization, the concentrations of PICP and PIIINP were determined for all patients by enzyme-linked immunosorbent assay (ELISA) using laboratory BCM Diagnostics kits (USA). All patients at the hospital received standard therapy. Results The following marker values were obtained: 1st day: PICP 609 (583; 635) ng/ml, PIIINP 26 (18.9; 34.9) ng/ml; 12th day: PICP 588 (580; 561) ng/ml, PIIINP 24.2 (18.6; 30.3) ng/ml. The following significant correlations were revealed: PICP 1st day / isovolumic contraction time – IVCT (m/s) 12th day, r=−0.68, p=0.042; PICP 1st day / Tei Index 12th day, r=−0.72, p=0.028; PICP 1st day / diastolic rigidity 12th day, r=−0.74, p=0.021; PIIINP 1st day/age, r=0.55, p=0.016; PIIINP 1st day/ body mass index (BMI), r=−0.59, p=0.009; PIIINP 1st day / E (cm/s) 1st day, r=0.72, p=0.018; PIIINP 1st day / Em /FPV 1st day, r=0.78, p=0.007; PIIINP 12th day / Em / FPV 1st day, r=0.65, p=0.041; PIIINP 12th day / E (cm/s) 1st day, r=0.67, p=0.033; PIIINP 12th day / E / Em) 12th day, r=0.70, p=0.023; PIIINP 12th day / Em/FPV 12th day, r=0.73, p=0.014. Conclusions The data obtained indicates the correlation between serum markers of myocardial fibrosis and the indices of echocardiography, as well as age. We conclude that, all the markers listed above, are able to represent myocardial remodeling in patients with STEMI. Funding Acknowledgement Type of funding source: None

Objectives. Incomplete ST-segment elevation resolution (STR) occasionally occurs despite successful revascularization of epicardial coronary artery after primary percutaneous coronary intervention (PPCI). The aim of this study was to evaluate the relationship between the degree of STR and the severity of microvascular dysfunction. Methods. A total of 73 consecutive patients with ST-segment elevation myocardial infarction (STEMI) who underwent successful PPCI were evaluated. Serial 12-lead electrocardiography was performed at baseline and at 90 minutes after PPCI. Microvascular dysfunction was assessed by index of microvascular resistance (IMR) immediately after PPCI. Results. Patients were classified into 2 groups: 50 patients with complete STR (STR ≥50%) and 23 patients with incomplete STR (STR <50%). The incomplete STR group had a higher IMR value and lower left ventricular ejection fraction (LVEF), compared with the complete STR group. The degree of STR was significantly correlated with IMR (r = −0.416, P=0.002) and LVEF (r = 0.300, P=0.011). These correlations were only observed in patients with left anterior descending artery (LAD) infarction but not observed in patients with non-LAD infarction. A cutoff IMR value was 27.3 for predicting incomplete STR after PPCI. Conclusion. Incomplete STR after PPCI in patients with STEMI reflects the presence of microvascular and left ventricular dysfunction, especially in patients with LAD infarction.

Residual Syntax Score

The purpose of this study is to investigate the relation between residual SYNTAX score (rSS) and contrast-induced nephropathy (CIN) development in patients with non-ST segment elevation myocardial infarction (NSTEMI) with normal or near-to-normal left ventricular ejection fraction (LVEF) who underwent percutaneous coronary intervention (PCI). A total of 306 patients who underwent PCI with NSTEMI were included in our study. SYNTAX scores were calculated for the periods before and after PCI. Patients were divided into 2 groups as developed CIN following PCI (CIN +) and patients did not (CIN −). Fifty-four (17.6%) of patients who were included in the study developed CIN. Age ( P = .001) and rSS ( P = .002) were significantly higher and LVEF was lower ( P = .034) in the CIN (+) group. Age ( P = .031, odds ratio [OR]: 1.031, 95% CI, 1.003-1.059) and rSS ( P = .04, OR: 1.036, 95% CI, 1.002-1.071) were independent predictors for CIN. In receiver operating characteristic analyses, when the cutoff value of rSS was taken as 3.5, it determined CIN with 79% sensitivity and 65% specificity. Contrast-induced nephropathy may develop more frequently in patients with increased rSS value. The rSS may be useful to follow-up these patients for CIN development.
