Thanks guys for all the thoughts and prayers for my father.He made it through the heart cath fine with suprisingly little blockage detected.The doc is going to continue to treat him with medication to improve his heart function and he is being released from the hospital as I type this.Our biggest problem now will be trying to get him to what the doc has told him(he can be stubborn as a mule).He is breathing much better and believe it or not the respitory doc said his lungs are still in good condition considering his smoking.He will supposedly be on no restrictions when he gets home and can do pretty much whatever his body will let him do(Including running a combine).Thanks again for the prayers and thoughts.
