This should do the trick:

(defmacro spam-fetch-field-fast (article field)
  "Fetch a field quickly, using the internal gnus-data-list function"
  (let ((macro (intern (concat "mail-header-" (symbol-name field)))))
    (if macro
	`(let ((article ,article))
	   (if (numberp article)
	       (let* ((header (assoc article (gnus-data-list nil)))
		      (data-header (if header (gnus-data-header header))))
		 (,macro data-header)))))))
