Angina surgery

I'm a 78-year-old patient with angina who walks daily in a park near my home. I have no symptoms when I walk slowly. However, when I walk briskly, I feel chest tightness and difficulty breathing, but after a while, I return to normal. After experiencing these symptoms for several days, I made an appointment with a doctor and underwent angina surgery at St. Carlo. I was discharged five days later and am now back to my regular walking routine. I've made it a habit to seek immediate medical attention if I notice any abnormalities in my body.
