[Chilean results of the international registry of risk factors and treatment of unstable angina and non ST elevation myocardial infarction: ACCORD (ACute CORonary syndrome Descriptive study)].

Background: Guidelines for the management of unstable angina (UA) and non ST elevation myocardial infarction (NSTEMI) have been issued, however, current practices are unknown in Chile.

Aim: To evaluate in a prospective cohort of NSTEMI patients the current practices, treatments and risk factors.

Material And Methods: One year prospective International non interventional registry, conducted in Chile between January 2005 and November 2006.

[Admission hyperglycemia and mortality of ST segment elevation myocardial infarction].

Background: hyperglycemia at admission has been associated to an adverse prognosis in patients with ST-segment elevation acute myocardial infarction (STE-MI). However, its impact over the results of reperfusion therapies in patients with STEMI is still a matter of controversy.

Aim: to determine the impact of admission hyperglycemia on hospital and long term mortality, according to the method of reper-fusion utilized in patients with STEMI.

[Mortality of patients with ST-elevation acute myocardial infarction treated with primary angioplasty or thrombolysis].

Background: Primary angioplasty is the most effective treatment of ST-segment elevation acute myocardial infarction (STEMI). However, its worldwide implementation is difficult to obtain. Therefore thrombolysis continues to be the treatment most commonly used.

[ln-hospital mortality after ST-segment elevation myocardial infarction according to reperfusion therapy].

Background: Primary angioplasty is considered the best reperfusion therapy in the treatment of ST-segment elevation myocardial infarction (STEMI). However, thrombolysis is the reperfusion method most commonly used, due to its wide availability, reduced costs and ease of administration.

Aim: To compare in-hospital mortality in STEMI patients according to reperfusion therapy.

[Results of the first Chilean registry of unstable angina. Clinical features, risk profile and treatment].

Background: From January 2000 to June 2002, the first Chilean registry of unstable angina was carried out, with the participation of 15 hospitals.

Aim: To report the clinical and demographic features of 600 patients with unstable angina, their risk profile and prognosis.

Material And Methods: The inclusion criteria for this prospective registry were a history of recent onset of chest pain (<48 hours) or a change in the character of previous angina, associated to ischemic electrocardiographic changes and/or positive markers of myocardial damage.
