Официальное название

A Prospective Danish National Registry of Percutaneous Transluminal Renal Angioplasty in Patients With Renovascular Hypertension

Обзор

A prospective Danish national registry of percutaneous transluminal renal angioplasty (PTRA) in high-risk patients with renal artery stenosis selected on the basis of common national criteria, and with a common follow-up protocol for all three Danish centres offering PTRA

Вмешательства

• Устройство Percutaneous transluminal renal angioplasty
  Angioplasty plus stenting (angioplasty in patients with fibromuscular dysplasia) Adjuvant therapy in atherosclerotic renal artery stenosis - at the discretion of the treating physician * Antiplatelet therapy (usually standard) * Cholesterol-lowering drugs (usually standard) * Antihypertensive treatment with angiotensin-converting-enzyme inhibitor or angiotensin-receptor blocker (normally not contraindicated) * Smoking cessation, diet and physical activity (usually standard)

Первичные конечные точки

• Changes in 24-hour ambulatory systolic and diastolic blood pressures from baseline to 24 months after PTRA in patients with 24-hour ambulatory average systolic blood pressure ≥ 150 mmHg at baseline [Срок оценки: Measured 24 months post-PTRA]

Вторичные конечные точки (8)

• Changes in 24-hour ambulatory systolic and diastolic blood pressures from baseline to 24 months after PTRA in patients with 24-hour ambulatory average systolic blood pressure ≥ 130 mmHg at baseline [Срок оценки: Measured 24 months post-PTRA]
• Changes in 24-hour ambulatory systolic and diastolic blood pressures (statistically adjusted for treatment changes) from baseline to 24 months after PTRA in patients with 24-hour ambulatory average systolic blood pressure ≥ 150 mmHg at baseline [Срок оценки: Measured 24 months post-PTRA]
• Changes in 24-hour ambulatory systolic and diastolic blood pressures (statistically adjusted for treatment changes) from baseline to 24 months after PTRA in patients with 24-hour ambulatory average systolic blood pressure ≥ 130 mmHg at baseline [Срок оценки: Measured 24 months post-PTRA]
• Changes in 24-hour ambulatory systolic and diastolic blood pressures (unadjusted and statistically adjusted for treatment changes) [Срок оценки: Measured at 3, 12, 36, 48 and 60 months]
• Change in antihypertensive treatment (defined daily doses) [Срок оценки: Measured at 3, 12, 24, 36, 48 and 60 months]
• Change in kidney function [Срок оценки: Measured at 3, 12, 24, 36, 48 and 60 months]
• Clinical composite end point [Срок оценки: Measured at 3, 12, 24, 36, 48 and 60 months]
• Safety composite end point (< 30 days after PTRA) [Срок оценки: Measured at 3, 12, 24, 36, 48 and 60 months]

Критерии участия

Eligibility criteria

• True resistant hypertension (≥ 3 antihypertensive drugs including a diuretic, if tolerated, and each prescribed at optimal doses) and uncontrolled blood pressure confirmed by 24-hour ambulatory blood pressure monitoring. The 24-hour ambulatory blood pressure monitoring is performed after nurse-administered medication and blood pressure measurements are performed hourly. If the average 24-hour ambulatory systolic blood pressure is ≥ 130 mmHg the patient can be evaluated for renal artery stenosis.
• Hypertension and intolerance or side effects of the antihypertensive treatment. Hypertension is confirmed by 24-hour ambulatory blood pressure monitoring. The 24-hour ambulatory blood pressure monitoring is performed after nurse-administered medication and blood pressure measurements are performed hourly. If the average 24-hour ambulatory systolic blood pressure is ≥ 130 mmHg the patient can be evaluated for renal artery stenosis.
• Progressive renal insufficiency (a reduction in eGFR > 5 ml/min/1,73 m2 per year) in patients with bilateral renal artery stenosis or in patients with renal artery stenosis and only one kidney.
• Recurrent heart failure/pulmonary edema and resistant hypertension (≥ 3 antihypertensive drugs including a diuretic, if tolerated, and each prescribed at optimal doses) that may not be attributed to non-compliance, reduced left heart ventricular ejection fraction/heart valve disease or other obvious explanations (atrial fibrillation, fever, hyperthyroidism etc.). If the average 24-hour ambulatory systolic blood pressure is ≥ 130 mmHg after nurse-administered medication the patient can be evaluated for renal artery stenosis.
• Younger patients (< 40 years) with hypertension (24-hour ambulatory blood pressure monitoring ≥ 130/80 mmHg after nurse-administered medication )

Критерии включения

All of the following:

• At least one of the above eligibility criteria
• Duplex doppler ultrasonography or renography investigations consistent with hemodynamically significant renal artery stenosis
• CT angiography or renal arteriography with angiographic renal artery stenosis of ≥ 70 % reduction of the luminal diameter in at least one projection

Критерии исключения

• If angiography/arteriography, ultrasonography or renography is consistent with bilateral significant renal artery stenosis and only one side is treated with PTRA
• PTRA of a renal artery supplying a kidney which pre-PTRA handles ≤ 10% of the total kidney function (with no blockage of the renin-angiotensin system) and has a kidney size < 7 cm (length)
