Last week I experienced a loss of breath and crushing tightness in my chest when climbing a large set of stairs.  I have had a chest xray and a pft done.  The function test showed that I am not fullly exhaling.  The Person doing the test said I should have my heart tested.  I have times of tightness/pain across my clavical.  almost like a pinching..and it goes up into my jaw at times.  I have been attending a jazzercise class for the last 9 monthths.  this past couple of weeks, I have been unable to workout with out  constantly stopping and have not been able to use the wieghts because my arms feel like lead.  What could be going on? I am a 49 yo female very well controlled hbp on benicar.  I am 55 230 lbs good blood sugar, high cholesteral

Hello, Yes this could be a cardiac problem due to blockages. You should get your ECG and echo done. You'll need TMT test if your ECG is normal. So visit cardiologist and get these things done.  You should avoid heavy activities till your evaluation is complete.  You should have a healthy lifestyle like avoiding fatty, oily and high calorie diet. Have low salt diet and monitor blood pressure regularly. Regular exercises like brisk walking, jogging according your capacity and symptoms at least 30 min a day and 5 days a week. Lots of green leafy vegetables, fruits, fish once or twice a week, avoid meat. Avoid smoking and alcohol if any. There shouldn't abdominal fat deposition or obesity. Get your lipid profile and sugars tested once.  You should get tab Arbitrate 5 mg sublingual whenever chest tightness occurs prescribed and have rest during such symptoms.
