Association between new-onset right bundle branch block and primary or secondary ventricular fibrillation in ST-segment elevation myocardial infarction.

Aims: New-onset right bundle branch block (RBBB) in myocardial infarction (MI) is often associated with ventricular fibrillation (VF) but the nature of this relationship has not been determined.

Methods And Results: Between 1998 and 2014, among other data, incidence and duration of RBBB and VF occurrence were prospectively collected in 5301 patients with ST-segment elevation MI (STEMI) admitted to two University Hospitals in Murcia (Spain). Multinomial adjusted logistic regression analyses were used to examine the association between RBBB, attending to its duration, and VF according to its primary VF (PVF) or secondary VF (SVF) character.

Effect of part-time cardiac catheterization facilities in patients with acute myocardial infarction.

Background: Although the easy availability of invasive cardiac care facilities is associated with an increase in their use, their influence on outcomes is not clear. We sought to investigate whether a newly available cardiac catheterization laboratory (CCL) performing percutaneous coronary intervention (PCI) on a part-time (PT) basis might improve outcomes in patients with acute myocardial infarction (AMI).

Methods: This was an observational cohort study that included all consecutive patients with AMI admitted to a secondary-level hospital in Spain before and after the PT-CCL opened in January 2006: during 1998-2005 and 2006-2014, respectively.

[Prognostic importance of cardiomegaly in patients with acute myocardial infarction].

Objectives: To assess the in-hospital and long-term prognostic importance of cardiomegaly demonstrated by a simple admission radiograph in patients hospitalized for acute myocardial infarction.

Material And Methods: Prospective study of 7644 patients admitted for acute myocardial infarction; 2 hospitals participated. We recorded detailed clinical data, especially noting the presence or absence of cardiomegaly in the chest radiograph.

Relation of New Permanent Right or Left Bundle Branch Block on Short- and Long-Term Mortality in Acute Myocardial Infarction Bundle Branch Block and Myocardial Infarction.

The aim of this study was to investigate the prognosis associated with bundle branch block (BBB) depending on location, time of appearance, and duration in patients with myocardial infarction (MI). From January 1998 to January 2008, we recruited 5,570 patients with acute MI. Thirty-day and 7-year all-cause mortality, according to BBB location, time of appearance, and duration were analyzed by multivariable analyses.

Educational Level and Long-term Mortality in Patients With Acute Myocardial Infarction.

Introduction And Objectives: The value of socioeconomic status as a prognostic marker in acute myocardial infarction is controversial. The aim of this study was to evaluate the impact of educational level, as a marker of socioeconomic status, on the prognosis of long-term survival after acute myocardial infarction.

Methods: We conducted a prospective, observational study of 5797 patients admitted to hospital with acute myocardial infarction.

Short- and long-term prognosis of previous and new-onset atrial fibrillation in ST-segment elevation acute myocardial infarction.

Introduction And Objectives: The impact of atrial fibrillation on the prognosis of myocardial infarction is still the subject of debate. We analyzed the influence of previous and new-onset atrial fibrillation on in-hospital and long-term prognosis in patients with acute myocardial infarction.

Methods: Prospective study of 4284 patients with ST-segment elevation acute myocardial infarction.

Impact of previous vascular burden on in-hospital and long-term mortality in patients with ST-segment elevation myocardial infarction.

Introduction And Objectives: Patients with a current acute coronary syndrome and previous ischemic heart disease, peripheral arterial disease, and/or cerebrovascular disease are reported to have a poorer outcome than those without these previous conditions. It is uncertain whether this association with outcome is observed at long-term follow-up.

Methods: Prospective observational study, including 4247 patients with ST-segment elevation myocardial infarction.

New regulations regarding Postgraduate Medical Training in Spain: perception of the tutor's role in the Murcia Region.

Background: Recently introduced regulatory changes have expanded the Tutor role to include their primary responsibility for Postgraduate Medical Training (PMT). However, accreditation and recognition of that role has been devolved to the autonomic regions. The opinions of the RT may be relevant to future decisions;

Methods: A comprehensive questionnaire, including demographic characteristics, academic and research achievement and personal views about their role, was sent to 201 RTs in the Murcia Region of Spain.

[Use of non-invasive ventilation in acute respiratory failure. Multicenter study in intensive care units].

Objectives: Study the use of non-invasive ventilation (NIV) in patients with acute respiratory failure in intensive care units (ICUs) in Spain.

Methods: A questionnaire was sent to 254 ICUs, after which, they were invited to participate in a multicenter, retrospective study, providing detailed information on ventilated patients.

Results: Answers were received from 123 hospitals.

[Female sex is inversely and independently associated with marked ST-segment elevation. A study in patients with ST-segment elevation acute myocardial infarction and early admission].

Introduction And Objectives: In patients with acute myocardial infarction, a number of variables in the initial ECG are useful prognostic indicators. The presence of ST-segment elevation, however, usually indicates the need for reperfusion therapy. The aims of this study were to investigate sex differences in the ECGs of patients with ST-elevation myocardial infarction (STEMI) and to look for a possible association between sex and marked ST-segment elevation.
