Lindsay's dad has been dealing with chest pains all year, and according to the site, a recent blood pressure test came back 200/110.

Papa Lohan will undergo surgery Friday to have a stent put in his heart.

Doctors hope this will help clear blood clots discovered in one of his lungs.

Back in February, Lohan had heart surgery to clear blockage in an artery of his heart.
