Background: Few studies have characterized electrocardiography (ECG) patterns correlated with left ventricular (LV) systolic dysfunction in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS).Objectives: This study aims to develop ECG pattern-derived scores to predict LV systolic dysfunction in NSTE-ACS patients.Methods: A total of 466 patients with NSTE-ACS were retrospectively enrolled. LV ejection fraction (LVEF) was assessed by echocardiography within 72 h after the first triage ECG acquisition; there was no coronary intervention in between. ECG score was developed to predict LVEF < 40%. Performance of LVEF, the Global Registry of Acute Coronary Events (GRACE), Thrombolysis in Myocardial Infarction (TIMI) and ECG scores to predict 24-month all-cause mortality were analyzed. Subgroups with varying LVEF, GRACE and TIMI scores were stratified by ECG score to identify patients at high risk of mortality.Results: LVEF < 40% was present in 20% of patients. We developed the PQRST score by multivariate logistic regression, including poor R wave progression, QRS duration > 110 ms, heart rate > 100 beats per min, and ST-segment depression ≥ 1 mm in ≥ 2 contiguous leads, ranging from 0 to 6.5. The score had an area under the curve (AUC) of 0.824 in the derivation cohort and 0.899 in the validation cohort for discriminating LVEF < 40%. A PQRST score ≥ 3 could stratify high-risk patients with LVEF ≥ 40%, GRACE score > 140, or TIMI score ≥ 3 regarding 24-month all-cause mortality.Conclusions: The PQRST score could predict LVEF < 40% in NSTE-ACS patients and identify patients at high risk of mortality in the subgroups of patients with LVEF ≥ 40%, GRACE score > 140 or TIMI score ≥ 3.

Abstract Objectives We aimed to assess the value of Global Registry of Acute Coronary Events (GRACE) and Thrombolysis in Myocardial Infarction (TIMI) risk scores (RSs) for predicting coronary artery disease (CAD) severity and prognosis in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS). Background Patients with NSTE-ACS are at varying risks of death and recurrent cardiac events, early risk stratification plays a central role, different scores are now available based on initial clinical history, ECG, and laboratory tests that enable early risk stratification on admission. Methods A prospective study was conducted including 100 patients (age, 45–68 years) with NSTE-ACS who were admitted at our hospital from January 2018 to January 2019. The two RSs (TIMI& GRACE) were calculated from the initial clinical history, electrocardiogram, and laboratory values collected and recorded on admission. All patients were subjected to conventional coronary angiography during admission, Patients were divided into two groups: 1) patients with syntax score ≤32 (test group, 80 patients) and 2) patients with syntax score >32 (comparative group, 20 patients). Median follow-up duration was 6 (4–9) days. Results Regarding correlation between coronary angiographic severity based on syntax score and the clinical profile based on the two RSs (TIMI&GRACE) in NSTE-ACS patients, statistically significant correlation were found between GRACE score and syntax score (r=0.789; P=0.001) with GRACE score accuracy: 94% and negative predictive value (NPV): 98.7%, whereas no statistically significant correlation were found between TIMI score and syntax score (r=0.087; P=0.388) with TIMI score accuracy: 32% and NPV: 73.1%. Conclusions In conclusion the GRACE score provides a quick and reliable prediction of CAD severity in NSTE-ACS patients, It allows accurate risk estimation, categorizes patients and consequently can help in making accurate therapeutic decisions either with the use of invasive strategies in high risk selected patients or the use of conservative strategies in low risk patients in presence of limited resources.

Objective: to study the effect of prehospital thrombolysis on left ventricular systolic dysfunction in patients with acute ST-segment elevation coronary syndrome.Material and methods: The study included 70 patients with acute coronary syndrome with ST-segment elevation. Patients were randomized into two groups: control (group A) - 35 patients receiving standard therapy, and hospital TLT. Group B included 35 patients who underwent standard therapy and prehospital TLT. All 70 patients underwent echocardiography 1 day after myocardial revascularization and 3 months later.Results: the use of early myocardial reperfusion in patients with STEMI had a positive effect on central hemodynamics, reduced the development of LV volume overload, as a result of which end-diastolic and systolic volumes did not change during 3 months of follow-up. LVEF grew in both groups, and its growth was more pronounced in group B.Conclusion: timely prehospital reperfusion reduces the severity of myocardial damage and thus prevents the development of severe systolic myocardial dysfunction LV.

The patients presenting acute coronary syndrome without ST segment elevation can have a short and long-term risk of death or recurrent ischemic events. Therefore, the evaluation of risk is an essential step in the management of such patients. We report two cases – a 86-year-old male, and a 46-year-old one – with acute coronary syndrome with non-ST-segment elevation, showing the importance of risk assessment to determine management strategy. Two risk profile scores were used: TIMI score and GRACE score. Routine use of validated risk score may facilitate more appropriate tailoring of intensive therapies, but the clinical reasoning of the physician is essential to take right decisions.

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.

Reversible Left Ventricular Dysfunction

Takotsubo syndrome (TTS) is a reversible left ventricular dysfunction characterized by local apical hypokinesia usually triggered by a physical or emotional stress. According to the last available data TTS may represent 2% of all admissions for acute coronary syndromes. Despite the reliable prevalence, diagnosis of TTS remains difficult. The initial presentation, both clinically and electrocardiographically, is similar to an acute myocardial infarction (AMI). The biomarker profile is also similar, although the peaks of troponin and creatinine kinase levels are lower, and brain natriuretic peptide levels are higher in patients with TTS compared with ST-segment elevation AMI. Modified Mayo diagnostic criteria are the most common for the diagnosis. Pathogenesis of TTS currently is not well understood. Catecholamines appear to play a central role in the pathophysiology of TTS. However, it is conceivable that some people have a genetic predisposition to stress-induced TTS. A genetic predisposition has been suggested based on the few familial TTS cases described. Despite reversible myocardial dysfunction, acute heart failure is the most common complication in the acute phase of TTS. In-hospital mortality rate is comparable to that of ST-segment elevation AMI. There are no randomized clinical trials to support specific treatment recommendations in TTS. It is believed that the tactics of managing patients with TTS hospitalized with suspicion of acute coronary syndrome should comply with the protocol of management of patients with AMI while acute coronary pathology is not excluded.

Background: Acute coronary syndrome (ACS) from non-ST-segment elevation myocardial infarction (NSTEMI) and Takotsubo (TK) cardiomyopathy present with similar initial clinical features and can result in left ventricular (LV) dysfunction and acute heart failure. Methods: This study was a retrospective case-control study that identified patients aged 18 years and older who presented with ACS and underwent cardiac catheterization. Results: There were a total of 321 patients in the TK group and 1031 patients in the NSTEMI group. There was significantly worse LV dysfunction in the TK group with average ejection fraction (EF) of 44.35% (±15.11%) versus NSTEMI with an average EF of 47.36% (±13.5%) ( P < .001). The presence of TK yielded of an odds ratio (OR) of 2.373 (95% confidence interval [CI]: 1.165-3.618) and presence of peripheral artery disease (PAD) yielded an OR of 2.053 (95% CI: 1.165-3.618). Conclusions: The presence of TK cardiomyopathy and PAD were independent predictors of patients who had LVEF of <35% and elevated B-type natriuretic peptide levels.

AbstractBackgroundTo analyze the cardio-protective effects of ticagrelor in patients with acute coronary syndrome with S-T segment elevation.MethodsThe sample was 200 patients who had been diagnosed with acute coronary syndrome accompanied by diabetes Mellitus type II. Only patients having ST segment elevation before the treatment were included. Then, the subjects were further randomly divided into an observation group and a control group. The control group of 100 patients received clopidogrel; the observation group of 100 patients of ticagrelor. The serous creatine kinase CK-MB, functional cardiac indexes of left ventricular end diastolic diameter (LVDD), cardiac troponin I, ventricular ejection fraction, and relevant major adverse cardiovascular events (MACE) were compared between the two groups.ResultsOne month after a percutaneous coronary intervention (PCI) the observation group showed better results against angina, stent thrombosis, and all-cause mortality compared with those of the control subjects. Six months after treatment, both groups suffered adverse reactions. The number of patients who suffered adverse reactions in respiratory tract in the observation group was higher than in the control group. The inhibition of platelet aggregation IPA of ticagrelor was found to be significantly higher than clopidogrel, having a significant p value.ConclusionTicagrelor can effectively protect myocardial function for patients with ST-segment elevation acute coronary syndrome accompanied by diabetes and can reduce the incidence of adverse reactions..
