I get annual complete phyicals, and the last two years I had occasion to undergo more extensive medical exams. Last April I had hip replacement surgery, well, not 36 hours after being released from hospital I was back in ER because I passed out. When they ran blood work they asked if I had any chest pain, to which I said nothing. Dr. told me I had elevated Troponin level and that may indicate heart attack so they admitted me. I underwent every test there is to monitor heart. Because I was three days out from hip replacement the treadmill test was out so I had and induced stress test. Bottom line, there was nothing wrong with my heart. The cardiologist told me, if you have a heart attack you will have high troponin levels, but not all high levels are because of an attack. When ever your body is under stress the level may be elevated. Mine were elevated because of the stress on my body because of the surgery. But they had to eliminate any possible heart problem before they could clear me. The other time, I was sure I was having a heart attack, and was admitted and also underwent every test there was. My symptom were classic heart attack symptom, chest pain, tightness in my jaw, pain in my left arm and back, and sweating. After all the test and three days in hospital it was determined the symptoms were caused by restriction in my esophagus, which mimic a heart attack. They preform a procedure to stretch my esophagus ( while I was under ) and that took care of the problem. Bottom line guys, give up the macho man crap and get complete annual physical. I am 73 and want to see my grand kids for many more years, and enjoy more years with my wife of 46 years. Speaking of surgery, I'm having left knee replace Feb. 9th. I hope I don't have same issue I had with hip replacement, passing out and ending up back in hospital to undergo all the same heart monitoring test.
