Does Erectile Dysfonction Allow to Evaluate Subendocardial Viability Among Treated Patients With Hypertension ? (DEVISE)

17. juli 2026 opdateret af: Assistance Publique - Hôpitaux de Paris

Does Erectile Dysfonction is Correlated to Subendocardial Viability Among Treated Patients With Hypertension ?

Erectile dysfunction (ED) is associated with subclinical atherosclerosis and may precede clinically apparent coronary artery disease by two to five years. It may therefore serve as an early warning sign of cardiovascular disease and help identify patients who could benefit from intensified cardiovascular risk-factor management. The subendocardial viability ratio (SEVR), also known as the Buckberg index, is obtained noninvasively from radial artery applanation tonometry. SEVR reflects the balance between myocardial oxygen supply and demand and has been associated with coronary flow reserve in patients with hypertension. The DEVISE study will compare SEVR between treated men with hypertension who have ED with those who do not. The study will also examine the associations between ED severity and arterial stiffness, central hemodynamics, exercise capacity, left ventricular mass, coronary artery calcium, high-sensitivity C-reactive protein, cardiovascular risk, and quality of life.

The question addressed in our study is whether an alteration in subendocardial viability represents subclinical coronary disease associated with ED.

Detaljeret beskrivelse

DEVISE is a monocenter, prospective, noninterventional, cross-sectional, observational study. Consecutive adult men receiving pharmacological treatment for hypertension who are admitted to the hypertension day hospital unit at Lariboisière Hospital for assessment of hypertension-mediated organ damage will be screened.

Participants will complete the five-item International Index of Erectile Function (IIEF-5) questionnaire. Participants will be classified into two groups according to the presence or absence of ED. ED is defined as an IIEF-5 score of 21 or lower and will be further categorized as mild (17-21), mild-to-moderate (12-16), moderate (8-11), or severe (5-7).

All cardiovascular examinations are performed as part of routine care except for the completion of the IIEF-5 and SF-12 questionnaires. Radial artery applanation tonometry will be used to derive the central aortic pressure waveform and calculate systolic arterial velocity reserve (SEVR), central pulse pressure, pulse pressure amplification, and the augmentation index. Carotid-femoral pulse wave velocity will be measured as an index of aortic stiffness. Other assessments will include a bicycle exercise test, echocardiography, noncontrast computed tomography for coronary artery calcium scoring, and blood testing, including high-sensitivity C-reactive protein. Additionally, SCORE2 or SCORE2-OP calculations will be performed, and the SF-12 quality-of-life questionnaire will be administered.

The study will include a total of 120 participants, with recruitment ending once 60 participants have been enrolled in each group. Each participant will be observed for one day, corresponding to the day-hospital visit. The planned recruitment period is 18 months.

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Subendocardial viability ratio (SEVR)
Tidsramme: Once, during the day-hospital visit
SEVR, expressed as a percentage, calculated from the central aortic pressure waveform obtained by radial artery applanation tonometry. SEVR is calculated as 100 × diastolic pressure-time integral / systolic pressure-time integral. The value will be compared between participants with and without erectile dysfunction.
