Acute coronary syndrome (ACS) is associated with very high morbidity and mortality. The American Heart Association estimates – approximately every 40 seconds an American has a myocardial infarction. The aim of this study was to evaluate the structural-functional peculiarities of heart remodeling in patients with acute coronary syndrome. Material and Methods. In this observational cohort trial there were observed 184 patients with ACS. Coronary angiography was performed at admission, and lesions that reduced the lumen area at 50% or more were considered angiographically significant. Transthoracic echocardiography was performed in accordance with recommendations of the American Society of Echocardiography. Results. The mean age of all observed patients with ACS was 64.6±11.9 years; 93 (50.5%) were males. ACS with persistent ST segment elevation more often was presented as the anterior-lateral myocardial infarction with persistent ST segment elevation (STEMI) – in 70 (50.0%) cases. Among patients with STEMI the left anterior descending coronary artery (LAD) was mostly affected as infarction-related artery (IRA): in 74 (52.9%) cases at initial urgent coronary angiography. Multivessel disease (MVD) was identified in 22 (15.7%) patients with STEMI. The most significant variations of EchoCG parameters were observed in STEMI patients with MVD on coronary angiography (Table 2): dilatation of left atrium and left ventricle (increased of End-diastolic volume (EDV), End-systolic volume (ESV), End-diastolic diameter (EDD) and End-systolic diameter (ESD)) and low ejection fraction (EF) of left ventricle. Low EF of left ventricle was observed in 6 patients with culprit of LAD, 3 patients with culprit of LCx and in 6 patients with MVD (φ=0.244; p<0.05). Conclusion. Acute STEMI is caused by significant left ventricle remodeling (dilatation and ejection fraction decrease) in case of multivessel disease in coronary angiography.

Abstract There are few case reports of cases of carotid and aortic dissection related to the ergotamine abuse, but the cases that affect the coronary arteries is a very rare coronary. We present a patient of a 48-year-old female with an ST-segment elevation myocardial infarction attributable to chronic ergotamine use. The coronary angiography showed dissection of right coronary artery proximal.

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.

Drugs that work on the hematologic system play an important role in helping to limit the morbidity and mortality that can be associated with an acute coronary syndrome. The pharmacology of the fibrinolytic agents, thrombin inhibitors, and antiplatelet agents is described. A case study of a woman having an ST-segment elevation myocardial infarction is reviewed to highlight the importance of drugs that work on the hematologic system.

Objectives: We sought to assess whether plasma neopterin predicts adverse clinical outcomes in patients with NSTEACS. Background: Circulating C reactive protein (CRP), a marker of inflammation, correlates with events in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). High neopterin levels - a marker of macrophage activation - predict cardiovascular events in stable angina patients but their prognostic role in NSTEACS has not been systematically evaluated. Methods: We prospectively assessed 397 patients (74 % men) admitted with NSTEACS: 169 (42.5%) had unstable angina and 228 (57.5%) non-ST-segment elevation myocardial infarction (NSTEMI). Blood samples for neopterin and CRP assessment were obtained at admission. TIMI risk score was also assessed among other clinical and biochemical variables. The study end point was the composite of cardiac death, acute myocardial infarction and recurrent angina at 180-days. Results: Baseline neopterin concentrations (nmol/L) were similar in unstable angina and NSTEMI patients (8.3 [6.5–10.6] vs 8.0 [6.2–11.1], p = 0.54). Fifty-nine patients (14.9 %) had events during follow-up (highest third (%) 21.5 vs 1 st and 2 nd thirds 11.5, log rank 7.341, p = 0.007). On multivariable hazard Cox regression, only neopterin (highest vs 1 st and 2 nd thirds, HR 2.15, 95 % CI [1.21–3.81]) was independently associated with the combined endpoint.CRP levels, however, were not significantly different in patients with events compared to those without events (adjusted HR = 0.98, p = 0.89, 95% CI 0.80 –1.21). Conclusion: Increased neopterin levels are an independent predictor of 180-day adverse cardiac events in patients with NSTEACS.

Abstract Introduction: The recent development of large networks dedicated to ST-segment elevation myocardial infarction (STEMI) led to a significant increase in the number of primary percutaneous interventions (p-PCI) parallel with mortality reduction in Acute Coronary Syndrome (ACS). The number of non ST segment elevation myocardial infarction (NSTEMI) is increasing and the highest mortality rates are encountered in patients with cardiogenic shock and/or out of hospital cardiac arrest associated to ACS. The aim of this study was to identify the factors associated with a higher mortality rate in a global population with acute coronary syndromes presented in the emergency department of a county clinical hospital which serves as a regional center for a STEMI network. Material and method: This is a retrospective study including 684 patients with acute coronary syndrome admitted in the Clinic of Cardiology from the County Clinical Emergency Hospital Tîrgu Mureș in 2014. In all the cases, the factors that correlated with in hospital mortality were identified and analyzed. Results: The incidence of arterial hypertension was significantly higher in patients admitted with unstable angina (75.0%) and STEMI cases with less than 12 hours onset of symptomatology (68.1%), while impaired renal function correlated with the presence of NSTEMI (66.6%). The presence of a multivessel disease was significantly correlated with cardiogenic shock. The localisation of the culprit lesion in the left anterior descending artery (LAD) significantly correlated with the development of cardiogenic shock, LAD culprit lesions being present in 44.4% of CS cases as compared with 21.7% of noCS cases in STEMI patients. In NSTEMI patients, the localisation of the culprit lesion in the left main artery (LM) significantly correlated with the development of cardiogenic shock, culprit lesions in the left main being present in 47.0% of CS cases as compared with 28.5% of noCS cases in STEMI patients. Conclusion: Patients presenting with out-of-hospital resuscitated cardiac arrest due to Acute Myocardial Infarction associate higher in-hospital mortality rates. In-hospital mortality seems to be highly correlated with the female gender, STEMI myocardial infarction and the presence of multivascular lesions.
