Implant of permanent pacemaker during acute coronary syndrome: Mortality and associated factors in the ARIAM registry.

Background: Patients with acute coronary syndrome complicated with high degree atrioventricular block still have a high mortality. A low percentage of these patients need a permanent pacemaker (PPM) but mortality and associated factors with the PPM implant in acute coronary syndrome patients are not known. We assess whether PPM implant is an independent variable in the mortality of acute coronary syndrome patients.

Takotsubo cardiomyopathy--a clinical review.

Stress cardiomyopathy is characterised by reversible left ventricular dysfunction. It simulates an acute coronary syndrome (ACS), presenting with precordial pain or dyspnoea, changes of the ST segment, T wave, or QTc interval on electrocardiogram, and raised cardiac enzymes. Typical findings are disturbances of segmental contractility (apical hypokinesia or akinesia), with normal epicardial coronary arteries.

Evaluation of the performance of echocardiography in acute coronary syndrome patients during their stay in coronary units.

Objectives: To evaluate the frequency and the factors associated with performance of echocardiography in acute coronary syndrome (ACS) patients during their stay in intensive care units or coronary care units (ICU/CCU).

Methods: Retrospective cohort study including all patients diagnosed with acute coronary syndrome-unstable angina (UA), acute myocardial infarction (AMI)-included in the 'ARIAM' Spanish multi-centre register. The study period was from June 1996 to December 2005.

Heart rupture predictors in Spanish myocardial infarction patients: evaluation using propensity score analysis.

Background: The aim was to evaluate factors associated with the development of heart rupture in a Spanish registry of acute myocardial infarction (AMI) patients.

Material/methods: This was a retrospective study of cohorts, including all patients diagnosed with AMI included in the ARIAM Spanish multicenter registry. The study period was from June 1996 to December 2005.

Sustained ventricular arrhythmias in unstable angina patients: results of the ARIAM database.

Background: The aim of this study was to investigate patients with unstable angina (UA) and the predictive factors of these arrhythmias and to determine whether this complication behaves as an independent variable with regard to mortality, increased length of stay in an ICU/CCU, and the performance of percutaneous coronary intervention (PCI).

Material/methods: The retrospective cohort study included all patients diagnosed with UA and included in the Spanish "ARIAM" database between June 1996 and December 2005. Univariate and multivariate analyses were performed to evaluate the factors associated with these arrhythmias.

Cardiogenic shock in acute coronary syndrome in the Spanish population.

Background: To evaluate the frequency and factors associated with cardiogenic shock (CS) in acute myocardial infarction (AMI) and unstable angina (UA) and percutaneous coronary intervention (PCI).

Material/methods: Spanish registry. The study period was June 1996 to December 2005.

[Mean length of stay and prognosis in unstable angina. Results from the ARIAM database].

Background And Objective: The objective of this project is to investigate the factors predicting mortality and mean length of stay in patients diagnosed with unstable angina (UA) during admission to the Intensive Care Unit or Critical Care Unit (ICU/CCU).

Patients And Method: A retrospective cohort study including all the UA patients listed in the Spanish ARIAM register. The study period comprised from June, 1996 to December, 2003.
