Hi I was taken into hospital with a dull ache after doing some endurance exercise. ECG was showing normal and blood pressure ok. Blood test showed trace of enzymes. After investigation with dye injected they found no blockage so no stent required but found mild cardio vascular desease from when I used to smoke. I quit 5 years ago after smoking for 25 years. The cardiologist said that I had a tiny heart attack and I am on medication for treatment. I have now arrived home and questions and anxiety has started to kick in. What is meant by tiny heart attack and mild cardio vascular desease? Is this serious or does tiny and mild mean I do not have to worry?
