Orders and judgments (two papers), Supreme Court, New York County (Louis York, J.), entered September 22, 2000, and order and judgment (one paper), same court (Jane Solomon, J.), entered April 20, 2001, which, in each of the above-captioned actions granted defendant’s motion to preclude the testimony of plaintiffs’ expert and for summary judgment dismissing the complaint, unanimously affirmed, without costs.
Expert testimony purportedly based on scientific principles or procedures is only admissible after the “principle or procedure has ‘gained general acceptance’ in its specified field” (People v Wesley, 83 NY2d 417, 422, quoting Frye v United States, 293 F 1013,1014). Plaintiffs failed to make such a showing in support of the admissibility of their expert’s testimony and, accordingly, defendant’s motion to preclude the expert’s testimony was properly granted, warranting the grant of summary judgment in defendant’s favor in each of the actions.
While plaintiffs’ expert’s citation, in the Greader action, of a study that indicated that Viagra use might cause deleterious cardiac consequences based on studies of responses in human tissue samples was relevant, it was not sufficient to support a finding that his conclusion that a causal link exists was based on generally accepted principles, where the study relied on failed to conclude that such a link existed, but only that enough evidence was presented to warrant further research.
Finally, plaintiffs’ expert’s citation of a consensus document of the American Heart Association and the American College of Cardiology showed, at best, support for the conclusion that persons with active coronary ischemia had not been adequately studied prior to marketing of the drug. It did not demonstrate a causal effect between ingestion of the drug and heart attacks in this population. Concur — Williams, J.P., Tom, Rosenberger and Wallach, JJ. [See 185 Misc 2d 600.]
