SAN ANTONIO -

Ken Slavin, 51, said he was a heart attack waiting to happen. 

That's because for years, he had ignored symptoms of fatigue, chest pains and a racing heartbeat.

He said he felt he didn’t need to worry since “all the test results kept saying everything was fine, and I knew something was wrong with me."

Finally, six weeks ago, he bit the bullet and saw his cardiologist, who found three arteries to his heart were 70 to 80 percent blocked. 

Just last week, he had three stents put in. 

He said when popular DJ Kidd Kraddick died over the weekend from heart problems, that could have easily been him if he kept ignoring the symptoms.

"People need to get checked out and need to be a little bit more thorough about what to ask for, because a standard physical will not necessarily find these problems," Slavin said.

It's not known what Kraddick did or didn't do in regards to his health. However, a local cardiologist said being proactive about your health is a step in the right direction.

Dr. Robert Schnitzler said, "Sit down with (your) doctor (and) get the appropriate testing. Begin an exercise program in a controlled circumstance and go from there."

He said procedures to clear blocked arteries don't fix patients, but helps blood travel through the arteries better. He also said people should always listen to their bodies and see their doctor once they experience change.

"The minute one finds they can't do what they did yesterday, they need to have it checked out. If it wasn't there before, it shouldn't be there now," Schnitzler said.

For Slavin, a fourth stent still needs to be done on another artery, but he knows now never to take his health for granted.
