Okay stress does not hamper the endothelial lining directly.
It only play a minor part.
Stress often releases cortisol in the body which in turn raises blood pressure and other things.
But you have to understand that the other factor like smoking , obesity ,
diabetes and hypertension are much more pivotal in deciding the overall cardiac and stroke risk.
If these 4 to 5 major risk factors are within check the risk of MI/Stroke (i am guessing this is why you are worried about endothelial lining damage) reduce drastically.
Next Steps
NOW with HsCRP , this measures inflamation with in turn produces a lot of endothelin and constricts the vessels reducing the efficacy of microvasculature in the heart and brain.
Few most common causes of raised HsCRP are obesity and metabolic syndrome and other inflammmatory conditions.
Health Tips
so a normal HsCRP is absolutely pointing towards a reasonable degree of safety from any major cardiac event.
Also stress is part and parcel of modern lifestyle learning to handle it beeter will be a lot better than avoiding it for health reasons.
