Prevalence and risk evaluation of cardiovascular disease in the newly diagnosed prostate cancer population in China:A nationwide,multi-center,population-based cross-sectional studyOACSTPCDMEDLINE

Background:Cardiovascular disease(CVD)has emerged as the leading cause of death from prostate cancer(PCa)in recent decades,bringing a great disease burden worldwide.Men with preexisting CVD have an increased risk for major adverse cardio-vascular events when treated with androgen deprivation therapy(ADT).The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China. Methods:Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling.CVD was defined as myocardial infarction,arrhythmia,heart failure,stroke,ischemic heart disease,and others.CVD risk was estimated by calculating Framingham risk scores(FRS).Patients were accordingly divided into low-,medium-,and high-risk groups.x2 or Fisher's exact test was used for comparison of categorical variables. Results:A total of 4253 patients were enrolled in the present study.A total of 27.0％(1147/4253)of patients had comorbid PCa and CVD,and 7.2％(307/4253)had two or more CVDs.The enrolled population was distributed in six regions of China,and approximately 71.0％(3019/4253)of patients lived in urban areas.With imaging and pathological evaluation,most PCa patients were diagnosed at an advanced stage,with 20.5％(871/4253)locally progressing and 20.5％(871/4253)showing metastasis.Most of them initiated prostatectomy(46.6％,1983/4253)or regimens involving ADT therapy(45.7％,1944/4253)for prostate cancer.In the present PCa cohort,43.1％(1832/4253)of patients had hypertension,and half of them had poorly controlled blood pressure.With FRS stratification,as expected,a higher risk of CVD was related to aging and metabolic disturbance.However,we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT.This was in accordance with clinical practice,i.e.,aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery.Among patients who underwent medical castration,only 4.0％(45/1118)received gonadotropin releasing hormone antagonists,in stark contrast to the grim situation of CVD prevalence and risk. Conclusions:PCa patients in China are diagnosed at an advanced stage.A heavy CVD burden was present at the initiation of treatment.Patients who accepted ADT-related therapy showed an original higher risk of CVD,but the awareness of cardiovascu-lar protection was far from sufficient.
