ABSTRACT

Objective To study the characteristics and clinical significance of the coronary plaques in patients with benign prostatic hyperplasia (BPH).Methods A total of 91 patients undergoing coronary artery angiography (CAG) were selected and divided into two groups according to with or without BPH,56 cases in BPH group,46 cases in control group.The qualitative and quantitative characteristics of 102 lesions area were analyzed by intravascular ultrosound (IVUS),including external elastic membrane-cross-sectional area (EEM-CSA),minimal lumen area (MLA),plaques area (PA),plaques burden (PB),reference external elastic membrane-cross-sectional area (REEM-CSA),reference minimal lumen area (RMAL),reference plaques area (RPA) and reference plaques burden (RPB).Results IVUS showed a higher rate of area stenosis than did the CAG [(58.2± 7.1)% vs.(55.9 ± 5.2)%,P<0.01].BPH group had more soft plaques,eccentric plaques,positive remodeling and less calcified than did the control group (P<0.05).The MLA and RMAL of BPH group were smaller than those of control group:MAL [(5.61±0.96) mm2 vs.(6.06±0.75) mm2,P<0.05],RMAL[(9.26±1.05) mm2 vs.(10.02±1.10) mm2,P<0.05]; while the EEM-CSA,PA,PB,RPA,RPB were larger than those of control group:EEM-CSA[(14.51±1.10)mm2 vs.(13.37±1.02)mm2],PA[(8.90±1.24) mm2 vs.(7.31±1.04) mm2],PB[(61.26±6.53)% vs.(54.53±5.69)%],RPA[(4.26±1.15) mm2 vs.(3.73±1.33) mm2],RPB [(31.30±8.37) % vs.(26.81±8.75) %,P<0.05].Conclusions IVUS has a higher value on evaluation of mild to moderate coronary artery stenosis.Evidence of myocardial ischemia in patients with BPH needs further excludeing coronary heart disease.
