In second subgroup, 12% were death becausedied of lung cancer, while 6.9% were deathdied because of a cardiac disease. OnThe multivariate analysis there isshowed that some factors affect longerthe cardiac-disease survival likelength: white race p = .005, female gender p < .0001, right-sided disease p = .003.
