Geebra asks why they did this study -- here is a section from the article (translation from the German by Google)
"In recent years, a relationship between PSA levels and cardiovascular conditions has been described.. It has been reported that prolonged cardiopulmonary resuscitation is frequently associated with increases of PSA serum level. Cardiogenic shock due to acute myocardial infarction diogenic shock due to acute myocardial infarction and coronary artery bypass surgery are associated with a rise in serum PSA. Therefore, the results of the previous studies suggest that PSA cannot be used for diagnosis of adenocarcinoma of the prostate during the first few weeks after these events"
So the answer is that it is fairly well known (the author gives 6 references) that there is a relationship between cardiac conditions and PSA level. If you have both, you may want to find a doctor who is knowledgeable about this.
Age at diagnosis 66, PSA 5.5
Biopsy 12/08 12 cores, 8 positive
CAT scan, Bone scan 1/09 both negative.
Robotic surgery 03/03/09 Catheter Out 03/08/09
Pathology: Lymph nodes & Seminal vesicles negative
Margins positive, Capsular penetration extensive Gleason 4+3=7
6 weeks: 1 pad/day, 1 pad/night -- mostly dry at night.
10 weeks: no pad at night -- slight leakage day/1 pad.
3 mo. PSA 0.0 - now light pads
6 mo. PSA 0.00 -- 1 light pad/day
