RESUMO
PURPOSE OF REVIEW: Hypertension remains one of the most common clinical problems leading to significant posttransplant complications. This study reviews the pathophysiology of hypertension in the postcardiac transplant phase and provides an update on currently available antihypertensive therapies for heart transplant patients. RECENT FINDINGS: The true prevalence of hypertension in the heart transplant population remains unknown. Effective blood pressure (BP) control is key to prevent left ventricular remodeling, diastolic dysfunction and stroke. Calcium channel blockers (CCBs) are the most commonly and preferred agents in the early posttransplant phase and may have renal protective effects. Angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs) can all be used as second line antihypertensive agents and may have a role in preventing other long-term complications such as calcineurin-inhibitor induced nephropathy. Although more data are needed, sodium-glucose co-transporter 2 inhibitors (SGLT2i) appeared to be well tolerated and could be considered especially in the presence of type diabetes and chronic kidney disease. Conversely, angiotensin receptor-neprilysin inhibition (ARNI) have not been studied in the heart transplant population therefore cannot be recommended at this time. SUMMARY: Hypertension is very common after heart transplant. Early steroid wean and traditional risk factor modification play an important part in the management of post-heart transplant hypertension. CCB, ACEI, ARB are the preferred antihypertensive agents to improve postcardiac transplant complications. Novel therapies such as SGLT2i appear well tolerated and may have benefits in both BP and glycemic control in heart transplant; however, larger trials are needed.
