Combination of TyG Index and GRACE Risk Score as Long-Term Prognostic Marker in Patients with ACS Complicated with T2DM Undergoing PCI.

ObjectiveWe aimed to investigate the prognostic value of the triglyceride-glucose (TyG) index combined the with Global Registry of Acute Coronary Events (GRACE) score in adult acute coronary syndrome (ACS) patients with type 2 diabetes mellitus (T2DM) who underwent percutaneous coronary intervention (PCI).MethodsThe study enrolled total 899 ACS patients with T2DM who underwent PCI. TyG index and the GRACE risk score were calculated and assessed by median. The correlation was analyzed by Spearman’s rank correlation coefficient. The cumulative major adverse cardiovascular event (MACE) curve was generated using the Kaplan–Meier method. Multivariate Cox regression was used to identify predictors of MACEs. Additionally, the receiver operating characteristic curve (ROC), net reclassification index (NRI) and Integrated Discrimination Improvement (IDI) were applied to analyze the performance of each single factor index and combined multivariate index in predicting MACE.ResultsIn the ACS patients with T2DM after PCI, there were significant differences in the TyG index and GRACE risk score between the MACE group and the MACE-free group (P < 0.001). Kaplan–Meier analysis showed that the TyG index combined with the GRACE risk score was positively correlated with the occurrence of MACEs (log rank P < 0.001). Multivariate Cox regression analyses showed that the TyG index, the GRACE risk score, and the TyG index combined with the GRACE risk score were independent predictors of long-term MACEs (adjusted HR: 1.805; 95% CI: 1.479–2.203, P < 0.001; adjusted HR: 1.012; 95% CI: 1.009–1.016, P < 0.001; and adjusted HR: 2.337; 95% CI: 1.805–3.025, P < 0.001, respectively). Correlation analysis indicated that the TyG index was positively correlated with the GRACE risk score (R = 0.140, P < 0.001). The analysis of AUC, NRI and IDI revealed that the combined multivariate index performed better prognostic role than each single factor index in predicting the occurrence of MACE.ConclusionBoth the GRACE risk score and the TyG index could be significant and independent predictors of clinical outcomes in ACS patients with T2DM after PCI. A combination of them could be enhanced predictions of clinical outcomes in these patients.

FREQUENCY, DISTRIBUTION AND DETERMINANTS OF DIABETES MELLITUS IN ADULT ACUTE CORONARY SYNDROME POPULATION OF D.I.KHAN DIVISION, PAKISTAN

Background: Global Health Estimates 2015 has shown IHD as second leading global cause of death and 3rd leading global cause for DALYs for 2015. The objectives of this study were to determine frequency, distribution and determinants of DM in adult acute coronary syndrome (ACS) population of D.I.Khan Division, Pakistan. Materials &amp; Methods: This cross-sectional study was conducted in Departments of Ophthalmology &amp; Community Medicine, Gomal Medical College, D.I.Khan, from February 1, 2017 to April 30, 2017. 331 cases were selected with margin of error 4.511%, 90%CL and 25% prevalence of DM in 73,438 adults assumed to have IHD. All indoor adult patients of ACS were eligible. Sex, age groups, and residence and presence of DM were variables. Frequency and distribution were analyzed by count and percentage. Hypotheses for distribution were substantiated by chi-square goodness-of-fit and of association by chi-square test of association. Results: Out of 331 patients with ACS, 225 (68.0%) were men and 106 (32.0%) women, 221 (66.8%) ≤60 years and 110 (33.2%) &gt;60 years, and 210 (63.4%) urban and 121 (35.6%) rural. Frequency of DM was 79/331 (23.87%). Out of 79 patients with DM, men were 44 (13.29%), women 35 (10.57%), age group ≤60 years 57 (17.22%), &gt;60 years 22 (6.65%), urban 53 (16.01%) and rural 60 (7.85%). Our prevalence of DM was lower than expected (p=.00214), our distribution by sex was similar to expected (p=.4993) while our distribution for age groups (p=.01209) and residence (p=.00005) were not similar to expected. Presence of DM was associated to sex (p=.011) but not to age groups (p=.0304) and residence (p=.5241). Conclusion: Prevalence of DM in adult ACS population of D.I.Khan Division, Pakistan was found lower than expected. The prevalence was more in men than women, more in younger age group (≤60 years) than older age group (&gt;60 years) and more in urban than rural population. Our prevalence of DM was lower than expected, our distribution by sex was similar to expected while our distribution for age groups and residence were not similar to expected. The presence of DM was associated to sex but not to age groups and residence.

2204Predicting the trajectory of depression following an acute coronary syndrome: the role of resilience

Abstract Background Depression is common in patients following an Acute Coronary Syndrome (ACS) substantially increases the risk of future events and mortality. Post-ACS depression typically resembles one of four longitudinal trajectories: chronic; absent; recovered, or delayed depression. Early identification of a patient's post-ACS depression trajectory will improve risk stratification, treatment implementation and risk management. Purpose To explore whether stable psychosocial traits, such as resilience, predict the trajectory of depression one month and 6 months following an ACS admission. Method Consecutive adult ACS patients (STEMI/NSTEMI) admitted to a large general hospital completed the Cardiac Depression Scale (CDS) and the Sense of Coherence scale during their admission, then one and six months following discharge. Results 132 ACS in-patients (males = 111; mean age = 63.13±13.47) satisfied enrolment criteria. Unconditional linear latent growth modelling identified a 3-class model for the trajectory of depression post-ACS (increasing depression; consistent non-depressed; decreasing non-depressed). For the increasing depression class, resilience at baseline was significant and negative compared to the consistent class, b=−0.06, Wald chi square (1) = 4.42, p=0.036 and the decreasing class, b=−0.09, Wald chi square (1) = 7.20, p=0.007. Conclusions Patients who reported lower levels of resilience during an ACS admission were significantly more likely to experience initially high levels of depressive symptoms (CDS ≥85) that exceeded the clinically relevant cut-off (CDS ≥95) at 6 months post-discharge. This study suggests that screening for resilience and depression will improve risk stratification for persistent and delayed depression post-ACS.

Emergence and Characterization of Acute Coronary Syndrome in Adults After Confirmed or Missed History of Kawasaki Disease in Japan: A Japanese Nationwide Survey.

Background: Acute coronary syndrome (ACS), which is emerging in adults long after confirmed (followed-up or lost-to-follow), or missed Kawasaki disease (KD), is poorly characterized.Methods and Results: A Japanese retrospective nationwide hospital-based questionnaire survey of ACS during 2000–09 was conducted to characterize such patients. Among a total of 67 patients (median age 35, male 76%) recruited, low conventional coronary risks (≤1/6) was noted in 75%, a diagnosis of ST-elevation and myocardial infarction or cardiac arrest in 66%, medication before ACS in 22% (warfarin in 4%), and no prior history of acute myocardial infarction in 94%. One-month mortality was 19%. KD diagnosis was made in 32 during acute illness (Group A), in which 17 were lost to follow, and retrospectively in the other 35 from coronary imaging at ACS (Group B). Group A developed ACS at lower coronary risks (≤2/5 in 87 vs. 65% in group B, p = 0.043) at a younger age (26.5 vs. 40 yo, p < 0.001). In group A, followed-up patients developed ACS under medication before ACS (87 vs. 0% in lost-to-follow patients, p < 0.001) for giant aneurysm in culprit lesions (69 vs. 29%, p = 0.030). One-month mortality was comparable between groups A and B, and between patients followed-up and lost-to-follow in group A. The culprit lesion in group A was characterized by the association of an aneurysm ≥6 mm in acute KD (100%), lack of significant stenosis (61%) or giant aneurysm (50%) in the long-term (median interval 16 y), and the presence of intravascular ultrasound-derived calcification at ACS (86%).Conclusions: The present retrospective nationwide questionnaire survey demonstrated nationwide emergence of initial ACS in young adults at low coronary risks, who are followed-up or lost-to-follow after confirmed KD and initial coronary aneurysms ≥6 mm.

Acute Coronary Syndrome in a Patient with a Single Coronary Artery

Coronary anomalies are rare congenital abnormalities and are often associated with complex congenital heart diseases and manifest in infancy or childhood. Single coronary artery arising from the sinus of Valsalva supplying the entire heart is one of these congenital anomalies. The prevalence is reported to be approximately 0.3 to 2.0% of the general population, mostly clinically asymptomatic and with good prognosis. However, in some cases this anomaly can present as acute coronary syndrome in adults. Literature reports of patients with both a single coronary artery and an acute coronary syndrome are sparse, and percutaneous coronary interventions in such cases are technically challenging. We report a case of a patient with a single coronary artery suffering from an acute coronary syndrom who underwent complex bifurcational percutaneous intervention and provide a review of the literature.

Evaluation of myocardial injury markers in the diagnosis of pediatric myocardial injury diseases

Pediatric cardiac injury is common in primary heart disease and secondary systemic diseases. The pathophysiological processes include ischemic injury or direct injury, as well as focal or diffuse myocardial inflammatory lesions. Myocardial injury markers, including myoglobin, creatine kinase isoenzyme muscle B and troponin, are first used for the diagnosis of acute coronary syndrome(ACS) in adult, and have greatly improved the efficiency of diagnosis with their sensitivity and specificity. However, due to the very different pathogenesis of myocardial injury in pediatric and adult ACS, as well as the particularity that children are in continuous growth and development, it is necessary to evaluate the value of the myocardial injury markers and their biological reference intervals in pediatrics.

Ratio between fms-like tyrosine kinase 1 and placental growth factor in children with congenital heart disease.

Serum levels of soluble fms-like tyrosine kinase 1 (sFlt-1), an antiangiogenic factor, and its binding protein, placental growth factor (PlGF), are altered in women with preeclampsia. Recently, the sFlt-1/PlGF ratio has been shown to predict acute coronary syndrome in adults. However, few reports have described the use of the sFlt-1/PlGF ratio for evaluating an abnormal hemodynamic load in children with congenital heart disease (CHD). The sFlt-1/PlGF ratio was determined in 20 children with atrial septal defects (ASD), 26 children with ventricular septal defects (VSD), 57 children with tetralogy of Fallot (ToF), 35 children who were Fontan candidates (Fontan), and 14 controls. The preoperative sFlt-1/PlGF ratios in the ASD, VSD, and Fontan were significantly higher than those in the controls and were significantly decreased after surgical repair in the ASD and VSD. In the ToF, the sFlt-1/PlGF ratio was highest after first-stage repair and second-highest after final-stage palliation compared with the preoperative levels. The sFlt-1/PlGF ratio was highest after first-stage repair and much lower after final-stage palliation in the Fontan. Furthermore, these ratios correlated with the degree of the ventricular volume overload and hypoxia. Our study clearly demonstrated that the sFlt-1/PlGF ratio increases with volume overload and persistent hypoxia after surgery with CHD. These findings may prove useful in the management of CHD in children.

Two Young Adults Who Had Acute Coronary Syndrome after Regression of Coronary Aneurysms Caused by Kawasaki Disease in Infancy

We report two young adult patients who had acute coronary syndrome after regression of coronary aneurysms caused by Kawasaki disease (KD). A 26 year-old man had acute anterior myocardial infarction at midnight after drinking alcohol. He had had bilateral coronary aneurysms caused by KD at the age of 8 months. Selective coronary angiograms (CAGs) at the age of 7 years revealed regression of both coronary aneurysms. He had no symptoms until the onset of acute myocardial infarction. The other patient was a 24 year-old man diagnosed as having a subendocardial infarction. He had had bilateral coronary aneurysms caused by KD at the age of 1 year. CAGs at the age of 9 years showed that both had regressed. It should be recognized that young adults with apparently normal coronary arteries angiographically after regression of large coronary aneurysms caused by KD may occasionally have acute coronary syndromes. We suspect intimal involvement of the coronary arterial wall after regression of the large aneurysms underlies the acute coronary syndrome in adults. Risk factors for atherosclerosis must be avoided in this population.
