PTSD and myocardial infarction.
Screening myocardial infarction patients for posttraumatic stress disorder Posttraumatic stress disorder
An anxiety disorder in some individuals who have experienced an event that poses a direct threat to the individual's or another person's life. may flag patients likely to be nonadherent to medication and at risk for cardiovascular readmission, said Dr. Eyal Shemesh of Mount Sinai Medical Center, New York.
Seventy-three patients were recruited at an Israeli cardiology clinic 6 months after MI and were followed for 1 year, from June to November 2001. All patients were prescribed aspirin therapy; 16% were found to be noncompliant, and 12% were suspected of resistance to aspirin as measured by platelet thromboxane thromboxane /throm·box·ane/ (-bok´san) either of two compounds, one designated A2 and the other B2. Thromboxane A2 is synthesized by platelets and is an inducer of platelet aggregation and platelet release functions and is a production (Psychosom. Med. 66: 521-26, 2004).
Of the 65 patients who answered psychiatric questionnaires, 20% reported above-threshold PTSD PTSD posttraumatic stress disorder.
posttraumatic stress disorder
Post-traumatic stress disorder (PTSD) symptoms. Fifty-five percent who admitted nonadherence and took the questionnaire had above-threshold PTSD. Only 13% of adherent patients who answered the questionnaire had above-threshold PTSD.
The investigators found that PTSD patients were more than twice as likely to be readmitted for a cardiovascular event during the 1-year follow-up than patients not meeting the threshold for PTSD.
