Among 168 patients with malignant hypertension treated with a renin-angiotensin system blocker protocol, 5-year renal survival was 90.8%, despite high rates of brain (93%) and heart (82%) damage.
Cohort (n=168)
Malignant hypertension is associated with highly prevalent, often asymptomatic organ damage, and an oral titration protocol with renin-angiotensin system blockers yields favorable 5-year renal survival.
BACKGROUND: Malignant hypertension, the most severe form of hypertension, is defined by high blood pressure and acute ischemic organ damage. It has a worse prognosis than other forms of hypertension, especially in black patients. New tools to assess organ damage, especially that of the heart and brain, are now available and may contribute to a better evaluation of these patients. This report improves knowledge of the characteristics of involved organs to facilitate diagnosis and to evaluate the effectiveness of our treatment protocol. METHOD: The Bordeaux registry, started in 1995, recruited 168 patients. In addition to evaluations of their eyes and kidneys, these patients had a systematic evaluation of their hearts with ECG and echocardiography and, since 2007, a systematic brain MRI. Blood pressure was lowered with a protocol based on blockers of the renin-angiotensin system started at a very low-dose with forced titration over 48 h. Only an oral route was used for antihypertensive medication. RESULTS: Systematic MRIs found significant brain damage in 93% of patients. Heart involvement was highly prevalent: 82% had left ventricular mass more than 60 g/m, and 56% had systolic dysfunction (estimated by global longitudinal strain). Renal involvement and thrombotic microangiopathy were respectively present in 55 and 15% of patients. Median follow-up was 48 months. Renal survival at 5 years was 90.8%, similar to other studies. CONCLUSION: Malignant hypertension is a systemic disease causing severe damage to the brain, heart, kidneys and eyes, even in absence of symptoms. Renin-angiotensin system blockers seem to be the cornerstone of treatment.
Rubin et al. (Fri,) conducted a cohort in Malignant hypertension (n=168). Renin-angiotensin system blockers was evaluated on Renal survival at 5 years. Among 168 patients with malignant hypertension treated with a renin-angiotensin system blocker protocol, 5-year renal survival was 90.8%, despite high rates of brain (93%) and heart (82%) damage.
