Im sorry to hear this. I will keep Mark in my prayers. 🙏
I have heard of 3-4-5 stents inserted during one heart surgery.
I had chest pains after eating a good steak in my mid-50’s. My heart would race to over 100 sitting down. And I had missing heart beats. I did not want heart surgery or drugs. So I chose walking more instead. Gradually I increased my walking to 30 miles every week playing 5 rounds of 18 holes. After a year of this, All chest pains went away. Irregular heart beats went away. Now at age 83 I have no heart issues.
I dare not stop daily exercise.
