OBJECTIVE: Prostate-specific antigen (PSA) is a well-known prostate cancer marker. Recent studies have shown that serum PSA levels can fluctuate in response to cardiovascular stress. In this study we aimed to determine if serum PSA levels correlate with the presence and stages of coronary artery disease (CAD) and whether PSA can be used as a marker for the diagnosis and severity of CAD.

PATIENTS AND METHODS: This was a retrospective chart review of male patients who underwent coronary angiography for suspected CAD. A total of 100 patients with angiographic data and baseline serum PSA measurements were included. Patients with previous history of coronary angiography, stent implantation, benign prostate hypertrophy, known prostate cancer or prostatitis were excluded.

RESULTS: The mean age was 57±10 years. Coronary angiography results were normal in 13%, non-obstructive CAD (non-critical plaque formation) in 16%, one-vessel disease in 21%, two-vessel disease in 30% and multi-vessel disease in 20%. Mean values of total and free serum PSA were 1.4±1.3 ng/mL and 0.4±0.4 ng/mL, respectively. Although there was an increasing trend of PSA with more advanced stages of CAD, no significant relationship was established (p > 0.05). Patients with hypertension had significantly elevated total and free serum PSA compared to normotensives. There is no comparison of PSA levels between patients with CAD and without CAD.

CONCLUSIONS: Our study suggests that there is no direct relationship between increasing levels of PSA and stage of CAD. Thus, PSA level does not appear to be a suitable marker for diagnosis or severity of CAD.
