Hi, I am a slightly overweight, unfit 37 year old male, and for the last year or more have been noticing that as I breathe out my heartbeat pushes air out in pulses. If I hum the pulses are very audible. This has been getting more noticeable over time. I m concerned I may have heart failure or an aortic aneurysm or something similar putting pressure on my lungs, transmitting my heartbeat to my breath. I have been alcoholic for years (drink 4-7 evenings a week, 8-10 drinks an evening, sometimes more), and have high blood pressure (140/90, sometimes 150/100). Thanks for your time
