Question:

What precautions should I take with evidence of LVOT obstruction?

The echocardiographic test of mine shows evidence of LVOT obstruction with resting PG 49.5 and provocative PG 86.7m Hg. What does this mean? What precaution should I take? Is there any medicine to stop further thickening of the wall? My LVEF is 60%. Can I do treadmill and gym/weight exercises? Thank you.

Answer:

by Texas Heart Institute cardiologist, Jorge F. Guttin, MD    

Jorge F. Guttin, MDLVOT [Left Ventricular Outflow Tract] obstruction means that the inside portion of the heart muscle has grown and, therefore, has made the cavity of the pumping chamber of the heart smaller. As the heart beats and tries to squeeze the blood out, the ingrown muscle creates a relative obstruction to the blood flow. There are medications aimed at reducing the functional impairment to the exiting blood flow, such as beta blockers and calcium channel blockers. Surgery may also be a treatment option. You should be careful not to become dehydrated or hypotensive. With regard to exercise, it is likely not advisable, but consult with your doctor.  Depending on the type and results of  therapy received, it may be permissible.
