Elevated troponin levels can be the result of the heart beating too fast, high blood pressure in the lung arteries, congestive heart failure, inflammation in the heart and cardiomyapothy, states MedlinePlus. Troponin levels can also be elevated due to long-term kidney disease and a blockage in the lung artery.
Some medical procedures also cause elevated troponin levels, such as radiofrequency ablation of the heart, open heart surgery, cardiac angioplasty and heart defibrillation, notes MedlinePlus. Elevated troponin levels often occur after a heart attack. Some patients experience elevated troponin levels six hours after a heart attack, while all patients experience them 12 hours after. The levels stay elevated about a week or two after the heart attack.
