I've been having chest pains, neck and shoulder pain. Nausea, increased sleeplessness and waking every hour. Shortness of breath, dizzyness and, or lightheadedness for over a month now, I went to the ER the night it all began and other than elevated dystolic blood pressure and irregular heart rate, every test was negative. EKG, Chest X-ray and blood enzyme count. It's been getting worse and I have read more than once that these are all symptoms that precede a heart attack in women. I am almost 23 5'9 142Lbs, and I have a pretty bad diet honestly. But there is also a high rate of heart disease on both sides of my family. My great grandmother died at 51 from a massive heart attack, as did her son. My grandfather had a quadruple bypass before he was 50, my mom has had mild heart attacks. My other grandfather has had multiple strokes, my cousin died at 19 when his heart burst from undiagnosed Dilatory Cardiomyopathy. I plan on returning to the ER hopefully tonight but as they were supposed to refer me to a cardiologist and didn't I'm not sure when I will be seeing one.
