On the second national day of mourning (there will be seven) in the wake of the death of Hugo Chávez, it was revealed that a massive heart attack is what killed the contentious Venezuelan leader. Even in his last throes of pain, the head of Venezuela’s presidential guard said Chávez expressed his desire to stay alive. “He couldn’t speak, but he said it with his lips ... ‘I don’t want to die. Please don’t let me die,’ because he loved his country, he sacrificed himself for his country,” said Gen. Jose Ornella, who spent the last two years with the president. Chávez was suffering from a respiratory infection following his fourth cancer surgery in December. The type of cancer has still not been specified.
