Hypertension after solid-organ transplantation: special considerations for management

PURPOSE OF REVIEW: Hypertension is one of the most common comorbidities affecting patients after solid organ transplantation. Here we review the mechanisms leading to hypertension, along with common practices in terms of medical management. Glucagon-like peptide-1 receptor (GLP-1R) agonists, baroreflex therapy, and renal denervation are common interventions utilized prior to heart transplant. Special considerations for their management throughout the perioperative and postoperative period are covered here. RECENT FINDINGS: Most common medical management includes utilization of calcium channel blockers, followed by angiotensin-converting enzyme inhibitors and angiotensin receptor blockers. GLP-1R agonists have shown significant benefit in recent cardiovascular outcome trials. Preoperative management centers around risks associated with slowed gastric emptying, while reinitiation after heart transplant must take into consideration initiation and tolerance of immunosuppressive therapies. Baroreflex activation therapy has been approved for therapy of heart failure, with many patients proceeding to heart transplant. The device is frequently deactivated after transplantation, with little published experience regarding reinitiation of therapy after heart transplant. There is renewed interest in renal denervation as a treatment for refractory hypertension. The incidence of hypertension after heart transplant in those patients that have undergone previous renal denervation remains unknown, however there is limited experience with its use after renal transplant. SUMMARY: Further studies are required to elucidate optimal medical management of hypertension following heart transplantation. GLP-1R agonists, baroreflex activation therapy, and renal denervation are emerging therapies prior to transplant that require further investigation.
