Cardiovascular disease in waitlisted hemodialyzed patients

Area of Science:

• Nephrology
• Cardiology
• Transplantation Medicine

Background:

• Cardiovascular diseases (CVD) significantly impact kidney transplant evaluations.
• Assessing cardiovascular status in hemodialysis patients awaiting transplantation is crucial.

Purpose of the Study:

• To evaluate the cardiovascular status and risk factors in hemodialysis patients on the kidney transplant waitlist.
• To compare cardiovascular profiles between waitlisted and non-waitlisted hemodialysis patients.

Main Methods:

• A cohort study involving 5,068 hemodialysis patients, comparing 449 waitlisted patients with 4,619 not considered for transplantation.
• Data collected included demographics, biochemical parameters, CVD prevalence, and blood pressure.
• Statistical analysis compared characteristics between the two groups.

Main Results:

• Waitlisted patients were younger, had lower comorbidity scores, lower BMI, and reduced prevalence of CVD and diabetes compared to non-waitlisted patients.
• Hypertension prevalence was similar, but waitlisted patients exhibited significantly higher systolic and diastolic blood pressure.
• Ultrafiltration volume was also higher in waitlisted patients.

Conclusions:

• Hemodialysis patients waitlisted for kidney transplantation represent a healthier cohort with fewer comorbidities.
• Despite being healthier, their blood pressure control does not meet current guideline targets.
• Reassessment of hypotensive medication and hypertension treatment strategies is recommended for this population.
