Apr 1, 12:14 PM EST Pope Clings to Life As His Health Worsens By VICTOR L. SIMPSON Associated Press Writer VATICAN CITY (AP) -- Pope John Paul II was clinging to life Friday as his condition deteriorated further. The Vatican said his breathing was shallow and his kidneys were failing after he suffered massive heart problems. "The general conditions and cardio-respiratory conditions of the Holy Father have further worsened," the Vatican said in a statement. "The clinical picture indicates cardio-circulatory and renal insufficiency." John Paul was taking part in the prayers of those assisting him, spokesman Joaquin Navarro-Valls said. Earlier, he said the 84-year-old pontiff suffered massive heart problems and was in "very grave" condition, but he was lucid and spent the morning celebrating Mass and receiving top aides, asking one to read him the biblical account of Christ's Crucifixion and burial.
