RESUMEN
OBJECTIVES: To demonstrate the feasibility and safety of performing elective percutaneous coronary intervention (PCI) during contrast reaction producing severe hypotension. BACKGROUND: The development of profound hypotension due to a contrast reaction requires emergency treatment and usually signals procedure termination. METHODS AND RESULTS: We report successful completion of planned PCI with blood pressure support with vasopressors during contrast-induced hypotension in nine procedures in three patients with previously known contrast reaction causing hypotension. CONCLUSIONS: This case series provides support for the feasibility and safety of performing successful planned PCI under blood pressure support in patients with contrast reaction causing severe hypotension. A management approach for considering intervention in the setting of contrast-induced hypotension is provided.

D-dimers have been discovered as by-products of fibrinolysis. In situations where the fundamental pathology is associated with increased thrombolytic activity, D-dimer assays could serve an integral role in the clinical workup, and have an already established role in the diagnosis of clinical disorders of venous thromboembolism, and disseminated intravascular coagulation. However, there is growing literature suggesting that this is not the only clinical scenario where D-dimers may be of significance. They may also become an important biomarker in coronary and carotid artery atherosclerosis and aortic diseases. Being a non-invasive and quick means of diagnosis, D-dimers are a cost-effective tool used for diagnosing diseases. With the future being steered in the direction of preventive cardiology, it is imperative for clinicians to understand how to effectively utilize biomarkers in order to diagnose disorders. In this context, we review D-dimer's origin, current clinical utility, and potential future applications.
