Psychological stress and cardiovascular risk among women in Brazilian communities: a cross-sectional study.

Psychosocial evaluations are rarely conducted with community-dwelling individuals, especially those with higher risk of cardiovascular disease. This study aims to evaluate the perceptual stress and cardiovascular risk among women in a large cross-sectional study performed in Brazilian communities. Subjects aged over 18 years were included out of 500 public basic health units (BHU) in Brazil.

Simultaneous use of amiodarone influences warfarin maintenance dose but is not associated with adverse events.

Background: Drug interaction studies selecting patients in a real-life setting are scarce, and most studies to date are characterized by a small sample size.

Objective: To evaluate the effect of amiodarone on warfarin maintenance dose and adverse events in an anticoagulation cohort from a tertiary cardiovascular service.

Methods: This study recruited 866 patients, and oral anticoagulant therapy was monitored by the prothrombin time expressed as the international normalized ratio (INR).
