I'd stick with Hap's advice here, but I'm wondering...
Did your doctor not give you one of those heart shaped pillows after the surgery and encourage you to cough a lot with the pillow against your chest?
Coughing helps keep cardiac arteries cleared. Many hospitals hand out the pillow to bypass patients encouraging them to cough for the sake of keeping the pipes flushed.
I have copd emphysema and I find that smoking actually slightly lowers my blood pressure after taking a nebulizer treatment for lung function maintenance.
disclaimer...the pillow thing might not apply to someone who's had heart valve surgery, if that's the case so go easy on me folks.
