Hi doctor! Doctor, tell me, I have had chest tightness and difficulty breathing for more than 7 years now, but every time I feel chest tightness like someone is squeezing my heart, breathing becomes harder. May I ask, if I have chest pain and shortness of breath for a long time, do I have heart disease? Since then, I have not had a heart check-up. Looking forward to your advice, thank you doctor!

I am 22 years old this year. Please tell me when I take a deep breath in my heart or the pain is like stretching a string or something, the pain goes away for a while and I often get startled. Three years ago, my breathing hurt and I couldn't move for about a minute. The doctor asked me to take a deep breath and have a heart attack and be startled? Do you have symptoms of heart disease?
