[Lipoprotein (a), D-Dimer and apolipoprotein A1 as markers of presence and severity of coronary disease].

Background And Objective: To examine the relationship between blood levels of lipids as well as haemostatic and inflammatory markers and the presence and severity of angiographically-evaluated coronary stenosis.

Material And Method: We included 897 patients (629 males and 268 females), aged 65.12+/-11.

Acute versus chronic myocardial ischemia: a differential biological profile study.

Objective: To determine the possible differences in lipid, thrombogenic and inflammatory marker concentrations and the presence of chronic and acute coronary artery disease (stable and unstable angina, respectively), comparing them with a group of control patients with normal coronary arteries.

Material And Methods: This prospective cohort study included 125 patients with unstable angina, 189 with stable angina and a control group of 83 patients with normal coronary arteries. Marker concentrations were measured in all 3 groups.

[Predictive value of lipoprotein (a) and apolipoprotein A1 in patients with angiographycally evaluated coronary stenosis].

Background And Objective: To examine the relationship between blood levels of lipids, hemostatic and inflammatory markers and the presence of angiographycally evaluated coronary stenosis.

Patients And Method: We included 397 consecutive patients (267 males and 130 females) who were admitted to the hospital because of an acute episode of chest pain. Each patient underwent a coronariography using the Seldinger technique.

Prevalence and biologic profile of aspirin resistance in patients with angiographically proven coronary artery disease.

Background: Aspirin protects from cardiovascular events. However, a number of patients who take this drug suffer events, probably due to aspirin resistance. The role of certain biologic variables that may affect resistance is still uncertain.
