Hello Doctor, My dad, 92 yrs old, woke at 2 AM last night with heavy night sweats. He said that it occurred earlier in the week also but he was not concerned at that time. In the morning, he had some light burning in his chest and symptoms similar to when he had a mild heart attach in 2005. That did concern him, he called 911, and was transported to the hospital. He is in the hospital now, sitting up, and undergoing tests. They did an EKG, and blood tests, and they have all been negative. They plan to keep him overnight, see how he does, and do additional testing (I don t know which ones) tomorrow. Your thoughts?
