Aims: Cardiogenic shock (CS) and cardiac arrest (CA) are serious complications in ST-elevation myocardial infarction (STEMI) patients, with lack of long-term data according to their timing of occurrence. This study sought to determine the incidence and relationship between the timing of occurrence and prognostic impact of CS and CA complicating STEMI in the long-term follow-up.
Methods And Results: We conducted a retrospective analysis of consecutive STEMI patients treated between 2004 and 2017.
Background: Data from over 4 decades have reported a higher incidence of silent infarction among patients with diabetes mellitus (DM), but recent publications have shown conflicting results regarding the correlation between DM and presence of pain in patients with acute coronary syndromes (ACS).
Objective: Our primary objective was to analyze the association between DM and precordial pain at hospital arrival. Secondary analyses evaluated the association between hyperglycemia and precordial pain at presentation, and the subgroup of patients presenting within 6 hours of symptom onset.
Background: It is well known that the occurrence of bleeding increases in-hospital mortality in patients with acute coronary syndromes (ACS), and there is a good correlation between bleeding risk scores and bleeding incidence. However, the role of bleeding risk score as mortality predictor is poorly studied.
Objective: The main purpose of this paper was to analyze the role of bleeding risk score as in-hospital mortality predictor in a cohort of patients with ACS treated in a single cardiology tertiary center.
Objective: To assess the impact of hyperglycemia in different age-groups of patients with acute myocardial infarction (AMI).
Research Design And Methods: A total of 2,027 patients with AMI were categorized into one of five age-groups: <50 years (n = 301), ≥50 and <60 (n = 477), ≥60 and <70 (n = 545), ≥70 and <80 (n = 495), and ≥80 years (n = 209). Hyperglycemia was defined as initial glucose ≥115 mg/dL.
Introduction: Oral beta-blockers improve the prognosis of patients with acute myocardial infarction, while atrial fibrillation worsens the prognosis of this population. The reduction of atrial fibrillation incidence in patients treated with beta-blockers could at least in part explain the benefits of this drug.
Objective: To investigate the effect of beta-blockers on the incidence of atrial fibrillation in patients with acute myocardial infarction.
Background: Little is known, especially in our country, about the influence of health insurance plans on the long term outcome of patients after acute myocardial infarction (AMI).
Objective: To assess the outcome of patients with AMI who are covered by the National Health System (SUS) or other health insurance plans.
Methods: We analyzed 1,588 patients with AMI (mean age of 63.
Background: Unstable atherosclerotic plaques activate blood cells which may adhere to the coronary endothelium causing vessel occlusion. However, it is unknown if different clinical syndromes associated with plaque rupture induce similar blood cell activation and adhesion to the endothelium.
Methods: We studied changes in adhesion molecule expression of platelets (GPIIb/IIIa), neutrophils--CD18, CD11b and L-selectin--and monocytes (CD14) after interaction with active lesions of patients with stable angina subjected to PTCA and patients with unstable angina (UA).
