As background, my father is quite
elderly at 85, suffering for the last five years from congestive
heart failure (CHF) following two
heart attacks 10 years ago. His condition has been treated successfully to date by use of lasix diuretic. His typical pattern had been to gain weight and after symptoms of CHF progressed, we would either increase the lasix dosage or if that did not work then he would be hospitalized where intravenous diuretic appeared to control the episode.
