BACKGROUND: Nonaspirin, nonsteroidal anti-inflammatory drugs (NANSAIDs) have been associated with arterial thromboembolic events in the general population. Our objective was to determine the prevalence of NANSAID use in patients diagnosed with cryptogenic emboli or paradoxical embolic events from a patent foramen ovale (PFO) or atrial septal defect (ASD) compared with a control population with an incidental PFO/ASD and no history of embolic events. METHODS: We performed a retrospective case-control study of 90 age-matched patients to assess the association of NANSAIDs with cryptogenic arterial embolic events in patients with and without a history of PFO/ASD. Odds ratios (ORs) were obtained by chi2 analysis. Multivariate analysis was conducted with a logistical regression method. RESULTS: Patients with cryptogenic embolic events had a high prevalence of prescription NANSAID use regardless of the presence of a PFO/ASD and were far more likely to have a history of NANSAID use than those with an incidentally discovered PFO/ASD and no history of arterial emboli (OR 4.30, 95% confidence interval 1.14-13.07, p = 0.01). CONCLUSIONS: Many patients previously diagnosed with paradoxical emboli may be experiencing the prothrombotic effects of NANSAIDs rather than a paradoxical mechanism for their arterial embolic event.

Paradoxical embolus is a rare complication of thrombolysis. With a high prevalence of clinically silent septal defects and widespread use of thrombolysis, recognition of the risks, clinical signs and symptoms is important. A case is reported of paradoxical embolus following thrombolysis in a woman with a previously undiagnosed patent foramen ovale.

This article discusses the common and uncommon side effects of heparin and heparin-like therapy. Most attention is devoted to heparin-induced thrombocytopenia, as it is the most clinically aggressive adverse reaction. Additionally, less common and several newly reported side effects are discussed.

Although several new anticoagulant drugs are in development, heparin remains the drug of choice for most anticoagulation needs. The clinical effects of heparin are meritorious, but side effects do exist. Important untoward effects of heparin therapy including heparin-induced thrombocytopenia, heparin-associated osteoporosis, eosinophilia, skin reactions, allergic reactions other than thrombocytopenia and alopecia will be discussed in this article.
