If erectile dysfunction appears, check cardiovascular health first — don’t treat it as a purely sexual issue

勃起功能出了问题,先去查心血管,别当成单纯的「那方面的事」

Source cost

A doctor’s visit costs just a few dozen yuan. Measuring blood pressure and running tests for blood sugar and cholesterol adds another hundred or so yuan. One trip to the hospital yields results after a few days.

Source return

Men with erectile dysfunction later develop cardiovascular disease at roughly 40% higher rates than other men, and heart attacks at about 60% higher rates. The younger a man is, the greater this difference becomes. This problem often shows up before any chest pain does. Therefore, it’s wise to check blood pressure, blood sugar, and cholesterol levels rather than simply self‑medicating.

28. If erectile dysfunction appears, check cardiovascular health first — don’t treat it as a purely sexual issue

Cost: A doctor’s visit costs just a few dozen yuan. Measuring blood pressure and running tests for blood sugar and cholesterol adds another hundred or so yuan. One trip to the hospital yields results after a few days.

In plain terms: Men with erectile dysfunction later develop cardiovascular disease at roughly 40% higher rates than other men, and heart attacks at about 60% higher rates. The younger a man is, the greater this difference becomes. This problem often shows up before any chest pain does. Therefore, it’s wise to check blood pressure, blood sugar, and cholesterol levels rather than simply self‑medicating.

Benefit: One meta‑analysis combined data from 14 long‑term studies involving 92,757 men, followed for an average of 6.1 years. Compared with men without erectile dysfunction, those with the condition faced higher risks as follows: overall cardiovascular events rose by roughly 44% (RR 1.44, 95% CI 1.27–1.63). Heart attacks increased by about 62% (RR 1.62, 95% CI 1.34–1.96). Cerebrovascular events rose by roughly 39% (RR 1.39, 95% CI 1.23–1.57). All‑cause mortality went up by about 25% (RR 1.25, 95% CI 1.12–1.39). No significant difference appeared for cardiovascular‑related deaths (RR 1.19, 95% CI 0.97–1.46). The risk elevation was greater in younger men and in those whose baseline cardiovascular risk was moderate. Studies that used questionnaire‑based diagnosis reported an RR of 1.61 (95% CI 1.38–1.86), while studies asking just one question gave an RR of 1.27 (95% CI 1.18–1.37).

Notes: These 14 studies tracked groups of men over time; they are not randomized controlled trials. Hence the “40% higher” figure reflects an association, not a proven cause‑and‑effect relationship. Occasional episodes do not count; the condition is considered present only when symptoms persist for three months or more. The tests recommended — blood pressure measurement, fasting blood‑glucose testing, plus cholesterol checks, smoking status assessment, and waist‑circumference measurement — are the same as those listed in sections 7 and 8 of this chapter. Avoid purchasing “male‑enhancement” supplements online; legitimate medications for this purpose are prescription drugs, and their instructions list nitrates as a contraindication — meaning men already taking nitroglycerin or similar drugs must not use them, as doing so can cause a sudden drop in blood pressure. For ways to improve erectile function, see section 29 (weight loss and smoking cessation can help). The benefit is rated “moderate” rather than “large”: the 44% figure represents the difference between two groups, not the actual reduction in mortality achieved by testing. It is also not “small”; unlike the situation described in section 27 (visible blood in urine), where detection alone is the benefit, here hypertension, diabetes, and abnormal cholesterol levels each have established treatments available.

28. 勃起功能出了问题,先去查心血管,别当成单纯的「那方面的事」

成本: 挂号几十元。量血压、抽血查血糖和血脂,一两百元。跑一趟医院,等几天结果。

说人话: 有勃起功能障碍的男性,后来得心血管病的比别人多约四成,心梗多约六成。越年轻的人差得越多。这个毛病常常比胸痛先出现。所以先去查血压、血糖、血脂,别自己买药压过去。

收益: 一篇荟萃分析把 14 项跟踪研究合起来算,共 92,757 名男性,平均跟踪 6.1 年。和没有勃起功能障碍的人相比,有这个问题的人后来的风险是这样。总的心血管事件高约 44%(RR 1.44,95% CI 1.27 到 1.63,这是可信范围)。心梗高约 62%(RR 1.62,1.34 到 1.96)。脑血管事件高约 39%(RR 1.39,1.23 到 1.57)。全因死亡高约 25%(RR 1.25,1.12 到 1.39)。心血管死亡那一项没有拉开差距(RR 1.19,0.97 到 1.46)。年龄越轻,倍数越高。本来心血管风险属于中等的那批人,倍数比高风险和低风险的人都高。用问卷判定的研究,算出来的倍数是 1.61(1.38 到 1.86)。只问一句话的研究是 1.27(1.18 到 1.37)

备注: 这 14 项都是跟踪一群人看结果的研究,不是随机分组试验。所以「多四成」是关联,不能当成因果。偶尔一两次不算数,持续三个月以上才按问题看。要查的东西和本节第 7、8 条是同一批:量血压、查空腹血糖,再加血脂、吸烟和腰围。别在网上买「壮阳」保健品。正规的那类药是处方药,说明书把硝酸酯类列为禁忌,正在用硝酸甘油这类药的人不能吃,一起用会让血压骤降。怎么改善见本节第 29 条(减重、戒烟能让勃起功能好转)。收益记「中」不记「大」:44% 是两群人的风险差距,不是「去查一次能降多少死亡」。也不记「小」:本节第 27 条(尿里出现肉眼看得见的血)那种信号只有检出率,而这里查出来的高血压、糖尿病、血脂异常都有现成的治疗办法。
