New York Times: “Mr. Sanders’s emergency — the sudden onset of chest pain known as angina — is one that thousands of other Americans experience each year. Mr. Sanders’s discomfort occurred at a campaign event on Tuesday night. Because it signaled acute heart trouble, the senator went to the hospital where doctors implanted two stents in one of the coronary arteries that nourish the heart.”
“Doctors often release patients who undergo such procedures in a day or two. Mr. Sanders remains in the hospital, and his campaign has closely guarded pertinent details about his heart condition and treatment, raising questions about the extent of his health issues.”
“Among other things, Mr. Sanders has not disclosed whether blood and electrocardiogram tests showed he had a heart attack. The senator and his campaign have not allowed reporters to interview his doctors.”
