Background: The literature lacks studies regarding the correlation between risk scores and coronary anatomy in acute coronary syndrome (ACS) OBJECTIVE: Correlate risk scores with the severity of the coronary lesion in ACS with non-ST elevation.
Methods: A total of 582 patients were analyzed between July 2004 and October 2006. The correlation between TIMI risk scores and GRACE (hospital and six months) scores was performed for patients with coronary lesion ≥ 50%, using Spearman's non-parametric method.
Background: The aim of this study was to identify novel candidate biomarker proteins differentially expressed in the plasma of patients with early stage acute myocardial infarction (AMI) using SELDI-TOF-MS as a high throughput screening technology.
Methods: Ten individuals with recent acute ischemic-type chest pain (<12 h duration) and ST-segment elevation AMI (1STEMI) and after a second AMI (2STEMI) were selected. Blood samples were drawn at six times after STEMI diagnosis.
Background: There is uncertainty as to the comparative prognostic value between cardiac troponin I (cTnI) and CK-MB in acute coronary syndrome (ACS).
Objective: To compare the prognostic value between cTnI and CK-MB mass in patients with ACS without ST-segment elevation.
Methods: 1,027 patients were analyzed in a prospective way in a tertiary cardiology center.
Background: The probability of adverse events estimate is crucial in acute coronary syndrome condition.
Objectives: To develop a risk score for the brazilian population presenting non-ST-segment elevation acute coronary syndrome.
Methods: One thousand and twenty seven (1,027) patients were investigated prospectively at a cardiology center in Brazil.
Objective: Describe clinical characteristics of patients (P) admitted to hospital with suspected acute coronary syndrome (ACS), identifying medical treatment and in-hospital mortality.
Methods: Evaluated were 860 patients with ACS from January through December, 2003. We evaluated baseline characteristics, ACS mode of presentation, medication during hospital stay, indication for clinical treatment or myocardial revascularization (MR) and in-hospital mortality.
Objective: Evaluate, based on the evolution of new biochemical markers of cardiac damage, if electrical cardioversion (ECV) causes myocardial injury.
Methods: Seventy-six patients (P) submitted to elective ECV for atrial fibrillation or atrial flutter were evaluated. Creatine phosphokinase (CPK), CK-MB activity, CK-MB mass, myoglobin and cardiac troponin I (cTnI) were measured before, and 6 and 24 hours after ECV.
