"What does this Heart Catheterization result mean?"

ZocdocAnswersWhat does this Heart Catheterization result mean?


showed that LAD has moderate diffuse disease from the mid to distal segment without obstruction. The first diagonal branch was very small with ostial lesion causing 50-60% stenosis, it was less than 1.5 mm in diameter. And borderline left ventricular dysfunction.what does it exactly means ? thank you doctors.


The best thing to do is to discuss these results with a cardiologist. Generally speaking, the first part of this catheterization report indicates that the patient in question here has a small amount of cornering artery disease or atherosclerosis. Coronary artery disease is a very common problem in the United States and results in blockages in the coronary arteries that bring blood to the heart muscle. In this case, there is some small amount of disease in the left anterior descending artery or LAD. The report here does not indicate how much blockage there is, but if they don't list a percentage so it must not be much. The diagonal is a smaller vessel that comes off of one of the larger vessels and it has about 50% blockage. Neither of these are likely to cause any symptoms of chest pain, though the diagonal lesion might at maximal exercise. Finally, the report indicates that there is some left ventricular dysfunction which might indicate a small amount of heart failure. Cardiac catheterization is not very good at determining this, so an echocardiogram would have to be done. Again, these kinds of results are best discussed with a cardiologist. He or she could discuss what further testing is needed which might include an echocardiogram and blood work to make sure that cholesterol levels are within target values. In addition, it would behoove this person to start an exercise program under the guidance of their cardiologist.
