Insights
Men with erectile dysfunction (ED) face a higher risk of cardiovascular (CV) death. However, oncological causes account for a similar proportion of deaths, often occurring sooner after ED onset.
Area of Science:
- Cardiovascular health
- Men's health
- Epidemiology
Background:
- The ultimate cause of death in men with erectile dysfunction (ED) remains unclear.
- Cardiovascular (CV) disease is a significant concern in men with ED.
Purpose of the Study:
- To investigate the causes of death in men diagnosed with ED.
- To assess the risk of cardiovascular death among men with ED.
Main Methods:
- Utilized statutory death registrations and hospital morbidity data for a linked-data study.
- Compared CV death risk in men with ED against a reference male population.
- Analyzed age-specific rates, mortality rate ratios (MRR), standardized mortality rate ratios (SMRR), and adjusted hazard ratios (HR).
Main Results:
- Men with ED exhibited a higher risk of CV death (SMRR 2.2).
- Pre-existing CV disease or prior hospital admissions for CV events increased CV mortality risk.
- The risk of CV death was notably higher in the 40-69 age group (MRR 4.1).
- Median time from ED manifestation to CV death was 10 years.
Conclusions:
- Men with ED have an elevated risk of cardiovascular mortality.
- Oncological causes represent a significant proportion of deaths in men with ED, comparable to CV causes.
- Oncological deaths tend to occur earlier after the initial manifestation of ED compared to CV deaths.
Introduction:
It is unclear whether men with erectile dysfunction (ED) ultimately die of cardiovascular (CV) causes.
Aim:
This study examined the causes of death in men with ED and their risk of CV death.
Methods:
Based on statutory death registrations and hospital morbidity data, the risk of CV death in men with ED in a linked-data study was assessed against the CV mortality risk in a reference male population.
Main Outcome Measures:
Deaths from CV causes as proportions of all deaths. Age-specific rate, mortality rate ratio (MRR), standardized mortality rate ratio (SMRR), and adjusted hazard ratio (HR).
Results:
CV mortality was 4.0%. Compared with the reference population, the risk of CV death was higher in men with ED (SMRR 2.2; 95% confidence interval [CI] 1.6, 3.0). Risk of CV mortality was higher in men with CV disease prior to ED (adjusted HR 1.7; 95% CI 1.1, 2.6) or with history of hospital admissions for CV events (adjusted HR 2.2; 95% CI 1.3, 3.8), compared with those without the respective history. MRR was significantly increased in the 40-69 years age group (MRR 4.1; 95% CI 3.2, 5.2). The median time interval between manifestation of ED and CV death was 10.0 years. A greater proportion of deaths from oncological than from CV causes (25.0% vs. 10.8%) occurred within the first 5 years of the manifestation of ED.
Conclusions:
Although the risk of CV mortality is greater in men with ED, almost as many men die of oncological as of CV causes, with a higher proportion of oncological deaths occurring sooner subsequent to the first manifestation of ED.
