Özet– Pulmoner hipertansiyon alanındaki önemli gelişmelerden sonra, en önemli görevlerden biri uzun dönem sonuçlarla ilişkili kinik tedavi hedeflerini belirleme gereksinimidir. Modifiye New York Kalp Cemiyeti fonksiyonel sınıf I veya II, 380 metreden fazla 6 dakika yürüme mesafesine ulaşma, ekokardiyografide sağ ventrikül boyutunun ve fonksiyonunun normalleşmesi, B-tip natriüretik peptit düzeyinin azalması ya da normalleşmesi ve sağ atriyal basıncının 8 mmHg’den düşük ve kardiyak indeksin 2,5 L/dk/m2 ’den büyük olması güncel hedeflerdir. Bununla birlikte, egzersiz kapasitesi ve sağ kalp fonksiyonu gibi uzun dönem sonuçlarla daha fazla ilişkili olan parametreleri hedefleyen daha güçlü ve net sınırlarla çizen “eşiğin” daha yüksek tutulması gerektiği açık hale gelmektedir; Özellikle, manyetik rezonans görüntüleme ve BNP/N-terminal pro B tip natriüretik peptit gibi doğru ve noninvaziv olarak sağ ventrikül fonksiyonunu belirleyen testler, temel belirleyiciler ve tedavi hedefleri olarak hizmet etmek için umut verici göstergeler olarak ortaya çıkmaktadır. Ayrıca, sonuçlar üzerine odaklı çalışmalar tek başına hiçbir testin güvenilir bir şekilde uzun vadeli prognostik belirteç olarak kullanılamayacağını ve birleşik tedavi hedeflerinin uzun dönem sonuçlarının daha iyi öngördüreceğini gösterdi. Yeniden düzenlenen tedavi hedeflerinin şunlar olduğu ileri sürülmüştür: Modifiye New York Kalp Cemiyeti fonksiyonel sınıf I veya II, ≥380 ve 440 m arasındaki 6 dakika yürüme mesafesi, kardiyopulmoner egzersiz testi-15 ml/d/kg’dan fazla tepe oksijen tüketim ölçümü ve 45 l/dak’dan az karbondioksit için solunum eşdeğeri, normale yakın BNP değeri, ile normal/normale yakın sağ ventrikül boyut ve fonksiyonlarını gösteren ekokardiyografi ve/veya kardiyak manyetik rezonans görüntüleme ve 8 mmHg’den az sağ atriyal basınçla ve 2,5-3 l/dak/m²’den fazla kardiyak indeksle birlikte sağ ventrikül fonksiyonunun normalleştiğini gösteren hemodinamik parametreler.

With significant therapeutic advances in the field of pulmonary arterial hypertension, the need to identify clinically relevant treatment goals that correlate with long-term outcome has emerged as 1 of the most critical tasks. Current goals include achieving modified New York Heart Association functional class I or II, 6-min walk distance >380 m, normalization of right ventricular size and function on echocardiograph, a decreasing or normalization of B-type natriuretic peptide (BNP), and hemodynamics with right atrial pressure <8 mm Hg and cardiac index >2.5 L/dk/m2. However, to more effectively prognosticate in the current era of complex treatments, it is becoming clear that the "bar" needs to be set higher, with more robust and clearer delineations aimed at parameters that correlate with long-term outcome; namely, exercise capacity and right heart function. Specifically, tests that accurately and noninvasively determine right ventricular function, such as cardiac magnetic resonance imaging and BNP/N-terminal pro-B-type natriuretic peptide, are emerging as promising indicators to serve as baseline predictors and treatment targets. Furthermore, studies focusing on outcomes have shown that no single test can reliably serve as a long-term prognostic marker and that composite treatment goals are more predictive of long-term outcome. It has been proposed that treatment goals be revised to include the following: modified New York Heart Association functional class I or II, 6-min walk distance 380 to 440 m, cardiopulmonary exercise test-measured peak oxygen consumption >15 ml/min/kg and ventilatory equivalent for carbon dioxide <45 l/min/l/min, BNP level toward "normal," echocardiograph and/or cardiac magnetic resonance imaging demonstrating normal/near-normal right ventricular size and function, and hemodynamics showing normalization of right ventricular function with right atrial pressure <8 mm Hg and cardiac index >2.5 to 3.0 l/min/m2.

Abstract

With significant therapeutic advances in the field of pulmonary arterial hypertension, the need to identify clinically relevant treatment goals that correlate with long-term outcome has emerged as 1 of the most critical tasks. Current goals include achieving modified New York Heart Association functional class I or II, 6-min walk distance >380 m, normalization of right ventricular size and function on echocardiograph, a decreasing or normalization of B-type natriuretic peptide (BNP), and hemodynamics with right atrial pressure <8 mm Hg and cardiac index >2.5 L/dk/m2. However, to more effectively prognosticate in the current era of complex treatments, it is becoming clear that the "bar" needs to be set higher, with more robust and clearer delineations aimed at parameters that correlate with long-term outcome; namely, exercise capacity and right heart function. Specifically, tests that accurately and noninvasively determine right ventricular function, such as cardiac magnetic resonance imaging and BNP/N-terminal pro-B-type natriuretic peptide, are emerging as promising indicators to serve as baseline predictors and treatment targets. Furthermore, studies focusing on outcomes have shown that no single test can reliably serve as a long-term prognostic marker and that composite treatment goals are more predictive of long-term outcome. It has been proposed that treatment goals be revised to include the following: modified New York Heart Association functional class I or II, 6-min walk distance 380 to 440 m, cardiopulmonary exercise test-measured peak oxygen consumption >15 ml/min/kg and ventilatory equivalent for carbon dioxide <45 l/min/l/min, BNP level toward "normal," echocardiograph and/or cardiac magnetic resonance imaging demonstrating normal/near-normal right ventricular size and function, and hemodynamics showing normalization of right ventricular function with right atrial pressure <8 mm Hg and cardiac index >2.5 to 3.0 l/min/m2.
