Nadciśnienie wtórne
Rokowania, prognozy i postęp choroby
Nadciśnienie wtórne stanowi 5-10% wszystkich przypadków nadciśnienia tętniczego i charakteryzuje się obecnością odwracalnej przyczyny podwyższonego ciśnienia krwi. Wczesne rozpoznanie i leczenie przyczyny podstawowej są kluczowe dla poprawy rokowania, zwłaszcza że nadciśnienie wtórne często jest oporne na standardową terapię przeciwnadciśnieniową. Wskazania do diagnostyki wtórnej obejmują ciężkie lub oporne nadciśnienie, początek przed 30. rokiem życia, złośliwe nadciśnienie oraz nagły wzrost ciśnienia. W diagnostyce pomocne są kliniczne i biochemiczne markery, takie jak płeć, skurczowe ciśnienie krwi oraz poziomy potasu w surowicy. Nowoczesne metody, w tym algorytmy uczenia maszynowego, wykazują wysoką skuteczność (AUC 0,924-0,965) w identyfikacji etiologii nadciśnienia wtórnego, co może usprawnić proces diagnostyczny i terapię.
Prognozy nadciśnienia wtórnego
Nadciśnienie wtórne (secondary hypertension) to postać nadciśnienia tętniczego z potencjalnie odwracalną przyczyną, która stanowi około 5-10% wszystkich przypadków nadciśnienia. Charakteryzuje się ono występowaniem konkretnego, identyfikowalnego czynnika wywołującego podwyższone wartości ciśnienia tętniczego krwi. Rokowanie w nadciśnieniu wtórnym jest ściśle związane z wczesnym wykryciem i odpowiednim leczeniem przyczyny podstawowej.12
Znaczenie wczesnej diagnozy
Nadciśnienie wtórne jest zwykle oporne na standardowe leki przeciwnadciśnieniowe, jeśli podstawowy mechanizm nie zostanie zidentyfikowany i odpowiednio leczony. Jednak przy wczesnej identyfikacji i leczeniu przyczyny podstawowej, nadciśnienie wtórne ma korzystne rokowanie.1 Wczesna diagnoza jest szczególnie istotna, ponieważ nieleczone nadciśnienie wtórne wiąże się z wyższym ryzykiem chorobowości i śmiertelności w porównaniu z nadciśnieniem pierwotnym.3
Należy rozważyć nadciśnienie wtórne w obecności sugestywnych objawów i oznak, takich jak:45
- Ciężkie lub oporne nadciśnienie tętnicze
- Początek przed 30 rokiem życia (zwłaszcza przed okresem dojrzewania)
- Złośliwe lub przyspieszone nadciśnienie tętnicze
- Nagły wzrost ciśnienia tętniczego z wcześniej stabilnych odczytów
Czynniki prognostyczne
W badaniach zidentyfikowano kilka łatwo dostępnych klinicznych i biochemicznych czynników predykcyjnych, które mogą pomóc w identyfikacji wtórnych przyczyn nadciśnienia u młodych dorosłych pacjentów z nadciśnieniem. Do kluczowych czynników należą: płeć, skurczowe ciśnienie krwi i poziomy potasu w surowicy.6
W jednym z badań opracowano nomogram pokazujący, że pacjenci z idiopatycznymi miopatiami zapalnymi (IIMs) w wieku powyżej 50 lat, z cukrzycą, wysokim poziomem trójglicerydów i cholesterolu LDL, dodatnim wynikiem ANA oraz osoby niepalące mają większe prawdopodobieństwo rozwoju nadciśnienia. Model ten wykazał dobrą zdolność dyskryminacyjną i kalibrację, co wskazuje na jego przydatność kliniczną.7
Zastosowanie uczenia maszynowego w prognozowaniu
Nowoczesne podejście do diagnozy etiologicznej nadciśnienia wtórnego wykorzystuje metody uczenia maszynowego (ML). Badania wykazały, że modele predykcyjne ML osiągnęły dobre wyniki w wykrywaniu 4 etiologii u pacjentów z podejrzeniem nadciśnienia wtórnego. Walidacja modelu prognostycznego złożonego wyniku osiągnęła AUC 0,924, podczas gdy 4 modele predykcyjne etiologii nadciśnienia wtórnego osiągnęły AUC 0,938-0,965 w zestawie danych walidacyjnych.8
Zastosowanie metod ML do diagnostyki etiologicznej nadciśnienia wtórnego może być przydatne w praktyce klinicznej. Ponieważ stosowanie elektronicznej dokumentacji medycznej staje się coraz bardziej powszechne w szpitalach, wygodne jest uzyskanie zintegrowanych danych klinicznych pacjenta. Algorytmy ML mogą kompleksowo analizować wszystkie uzyskane informacje o pacjentach i będą bardziej ukierunkowane i elastyczne niż tradycyjne wytyczne.9
Rokowanie w zależności od przyczyny
Nadciśnienie naczyniowo-nerkowe
Nadciśnienie naczyniowo-nerkowe jest częstą, potencjalnie odwracalną przyczyną nadciśnienia wtórnego. Chociaż może przyczyniać się tylko do 1% łagodnych przypadków nadciśnienia, odpowiada za 10% do 45% przypadków ciężkiego lub złośliwego nadciśnienia u pacjentów rasy białej.10
Randomizowane badania kontrolowane wykazały, że terapia medyczna jest równa rewaskularyzacji, z podobnymi wskaźnikami kontroli ciśnienia krwi i zgonów z przyczyn sercowo-naczyniowych, i bez związanych z nią powikłań operacyjnych. Pacjenci z zwężeniem tętnicy nerkowej powinni być leczeni inhibitorami konwertazy angiotensyny lub antagonistami receptora angiotensyny, o ile nie ma przeciwwskazań do ich stosowania.1112
Pierwotny hiperaldosteronizm
Pierwotny hiperaldosteronizm jest obecnie uważany za jedną z częstszych przyczyn nadciśnienia wtórnego. Najlepszym początkowym testem w kierunku aldosteronizmu jest pomiar stosunku aldosteronu do reniny.1314 Pierwotny aldosteronizm należy rozważyć u pacjentów z ciężkim nadciśnieniem.15
Obturacyjny bezdech senny
Obturacyjny bezdech senny (OSA) jest wiodącą przyczyną nadciśnienia wtórnego poddającą się leczeniu. Jest to szczególnie istotna przyczyna u osób w wieku 40-59 lat, ale rzadziej występuje u osób w wieku 60 lat i starszych.1617
Guz chromochłonny
Guz chromochłonny należy podejrzewać, gdy występują napadowe podwyższenia ciśnienia krwi. Diagnoza jest ważna ze względu na następstwa sercowo-naczyniowe i fakt, że nadciśnienie jest w dużej mierze odwracalne po operacji.1819
Inne przyczyny
Inne istotne przyczyny nadciśnienia wtórnego o różnym rokowaniu to:
- Zespół Cushinga – charakteryzuje się klasycznymi cechami, takimi jak twarz księżycowata, otyłość centralna, osłabienie mięśni proksymalnych i wybroczyny20
- Koarktacja aorty – częsta przyczyna nadciśnienia wtórnego u dzieci, szczególnie płci męskiej, ale może nie być wykryta aż do dorosłości, ponieważ często jest bezobjawowa21
- Niedoczynność tarczycy – może powodować podwyższenie ciśnienia rozkurczowego22
- Nadczynność tarczycy – może powodować podwyższenie ciśnienia skurczowego, prowadząc do zwiększonego ciśnienia tętna23
Efekty leczenia nadciśnienia wtórnego
Nadciśnienie wtórne ma pozytywne rokowanie po leczeniu. Wczesne wykrycie i leczenie może obniżyć ryzyko uszkodzenia naczyń krwionośnych i serca spowodowane utrzymującym się wysokim ciśnieniem krwi.24
Oznacza to, że nadciśnienie wtórne może ustąpić. Ciśnienie krwi może powrócić do normy po leczeniu przyczyny podstawowej. Jednak możliwe jest również, że ciśnienie krwi pozostanie wyższe niż powinno być. Może to wynikać z istnienia innej przyczyny. W takim przypadku może być konieczne przyjmowanie leków, aby utrzymać je w zdrowym zakresie.25
Czynniki wpływające na rokowanie
Głównymi czynnikami wpływającymi na rokowanie pacjentów z nadciśnieniem wtórnym są:
- Wczesne wykrycie przyczyny podstawowej26
- Możliwość odwrócenia przyczyny podstawowej27
- Współistniejące schorzenia28
- Już istniejące uszkodzenia narządów spowodowane długotrwałym nadciśnieniem29
- Wiek pacjenta i czas trwania nadciśnienia przed diagnozą30
Znaczenie biomarkerów w prognozowaniu
Zidentyfikowano kilka łatwo dostępnych klinicznych i biochemicznych czynników predykcyjnych, które mogą pomóc w identyfikacji wtórnych przyczyn nadciśnienia u młodych dorosłych pacjentów z nadciśnieniem. Jednak, podczas gdy osoby niemające tych czynników predykcyjnych mogą mieć niższe ryzyko nadciśnienia wtórnego, markery te powinny być używane wraz z kompleksową oceną kliniczną i nie mają służyć jako ostateczne kryteria diagnostyczne.31
Rozwój modeli uczenia maszynowego do diagnozowania przyczyn nadciśnienia wtórnego pokazuje obiecujące wyniki w prognozowaniu i może potencjalnie pomóc w podejmowaniu decyzji klinicznych, co może zwiększyć i rozszerzyć skuteczność klinicystów oraz pomóc w opracowaniu bardziej inteligentnych, wydajniejszych i wygodniejszych trybów diagnostyki nadciśnienia.32
Podsumowanie rokowań
Rokowanie w nadciśnieniu wtórnym jest zasadniczo korzystne pod warunkiem wczesnego wykrycia i odpowiedniego leczenia przyczyny podstawowej. Możliwość całkowitego wyleczenia zależy od etiologii nadciśnienia, co podkreśla znaczenie dokładnej diagnostyki. Nawet w przypadkach, gdy całkowite wyleczenie nie jest możliwe, właściwe leczenie może znacząco poprawić kontrolę ciśnienia tętniczego i zmniejszyć ryzyko powikłań sercowo-naczyniowych.3334
Częstość występowania wtórnych przyczyn nadciśnienia wynosi około 3,4%, w porównaniu z innymi badaniami, które wykazały częstość występowania w zakresie od 2 do 8%. Należy zauważyć, że nadciśnienie wtórne jest częstsze u osób młodszych, z częstością występowania bliską 30% u osób w wieku 18-40 lat z nadciśnieniem.3536
Nowoczesne podejścia diagnostyczne, w tym zastosowanie algorytmów uczenia maszynowego, oferują obiecujące narzędzia do poprawy wczesnego wykrywania nadciśnienia wtórnego, co może przełożyć się na lepsze wyniki leczenia i ogólne rokowanie pacjentów.3738

Secondary hypertension is usually resistant to antihypertensive drugs if the underlying mechanism is not identified and treated appropriately. […] However, with early identification and treatment of the underlying cause, secondary hypertension has a favorable prognosis.
- #2 Diagnosis of Secondary Hypertension: An Age-Based Approach | AAFPhttps://www.aafp.org/pubs/afp/issues/2010/1215/p1471.html
Secondary hypertension is a type of hypertension with an underlying, potentially correctable cause. […] Approximately 5 to 10 percent of adults with hypertension have a secondary cause. […] Secondary hypertension also should be considered in patients with resistant hypertension, and early or late onset of hypertension. […] Whenever a patient is diagnosed with hypertension, one purpose of the initial assessment (i.e., history, physical examination, and basic laboratory testing) is to exclude possible secondary causes. […] Indications for further investigation into a possible secondary etiology in the absence of suggestive signs and symptoms include resistant hypertension (defined as elevated blood pressure despite patient adherence to optimal dosages of three antihypertensive agents, including a diuretic), early or late onset of hypertension, a severe or accelerated course, or specific drug intolerances.

Background: Secondary hypertension is a kind of hypertension with a definite etiology and may be cured. Patients with suspected secondary hypertension can benefit from timely detection and treatment and, conversely, will have a higher risk of morbidity and mortality than those with primary hypertension. […] The ML prediction models in this study showed good performance in detecting 4 etiologies of patients with suspected secondary hypertension; thus, they may potentially facilitate clinical diagnosis decision making of secondary hypertension in an intelligent way. […] Based on the EMRs from Fuwai Hospital, we developed 5 prediction models with good performance for 4 etiologies of secondary hypertension using XGBoost. Validation of the composite outcome prediction model achieved an AUC of 0.924, while the 4 prediction models of the secondary hypertension etiologies achieved AUCs of 0.938-0.965 in the validation data set. The observed model performance suggested that it was feasible to derive effective ML prediction models of secondary hypertension, which may play important roles in predicting etiologies of patients with suspected secondary hypertension.
- #4 Secondary Hypertension: Discovering the Underlying Cause | AAFPhttps://www.aafp.org/pubs/afp/issues/2017/1001/p453.html
Secondary hypertension is a type of hypertension with an underlying and potentially reversible cause. It makes up only a small fraction (5% to 10%) of hypertensive cases. The prevalence of secondary hypertension varies by age and is more common in younger persons, with a prevalence close to 30% in those 18 to 40 years of age with hypertension. […] Secondary hypertension should be considered in the presence of suggestive signs and symptoms such as severe or resistant hypertension, onset before 30 years of age (especially before puberty), malignant or accelerated hypertension, and an acute rise in blood pressure from previously stable readings. […] Renovascular hypertension is a common, potentially reversible cause of secondary hypertension. Although it may contribute to only 1% of mild hypertension cases, it accounts for 10% to 45% of severe or malignant hypertension cases in white patients.

Several easily obtainable clinical and biochemical predictors, such as sex, systolic blood pressure, and serum potassium levels, could aid in identifying secondary causes of hypertension in young adult patients. […] The present study reported a prevalence of secondary causes of hypertension (3.4%), compared to other studies which reported a prevalence ranging from 2 to 8%. […] The key finding in this study was the identification of three easily obtainable clinical and biochemical factors that could predict secondary causes of hypertension in young hypertensive adults. […] While individuals lacking these predictors may be at a lower risk for secondary hypertension, these markers should be used alongside a comprehensive clinical evaluation and are not meant to serve as definitive diagnostic criteria. […] Therefore, primary aldosteronism should be considered in patients with severe hypertension.
- #7 Development of the prediction model for hypertension in patients with idiopathic inflammatory myopathieshttps://pmc.ncbi.nlm.nih.gov/articles/PMC8678666/
Cardiac involvement is an important cause of morbidity and mortality in patients with idiopathic inflammatory myopathies (IIMs). Hypertension, an important cardiovascular risk factor for the general population, has a crucial role in heart involvement. However, few studies have focused on the hypertension associated with IIMs. This study aimed to develop and assess the prediction model for incident hypertension in patients with IIMs. […] The nomogram showed that age 50 years, diabetes mellitus, high levels of TG and LDLC, positive ANA and nonsmokers were more likely to develop hypertension in IIMs patients. In addition, the Cindex of the nomogram and the internal validation was good, which indicated this predictive model had good discriminative ability and calibration. Meanwhile, the decision curve analysis revealed this nomogram had good clinical usefulness. Clinicians can use these features to assess the risk of hypertension in IIMs patients, and early preventive measures should be taken to reduce the incidence of hypertension in highrisk patients.

Application of ML methods to etiological diagnosis of secondary hypertension can be useful in clinical practice. As the use of EMRs is becoming increasingly common in hospitals, it is convenient to obtain an individuals integrated clinical data. ML algorithms can comprehensively analyze all the obtained information of patients, and will be more targeted and flexible than traditional guidelines. […] Based on the EMRs from Fuwai Hospital, 5 ML prediction models with good performance and applicable to etiologies detection of secondary hypertension in all age groups of adults were developed, which demonstrated that ML approaches were feasible and effective in the diagnosis of secondary hypertension. Such prediction models have the potential to help clinical decision making which may augment and extend effectiveness of the clinicians and help to develop more intelligent, more efficient, and more convenient hypertension diagnosis modes.

Randomized controlled trials have shown that medical therapy is equal to revascularization, with similar rates of blood pressure control and cardiovascular deaths, and without the associated complications of surgery. […] Patients with RAS should be treated with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers unless there are contraindications to their use. […] Primary hyperaldosteronism is now considered one of the more common causes of secondary hypertension. […] OSA is a leading treatable cause of secondary hypertension. […] Pheochromocytoma should be suspected when there are paroxysmal elevations in blood pressure. […] Cushing syndrome has classical features of moon facies, central obesity, proximal muscle weakness, and ecchymosis. […] Coarctation of the aorta is a common cause of secondary hypertension in children, especially males, but may not be detected until adulthood because it is often asymptomatic. […] Hypothyroidism can cause an elevation in diastolic blood pressure, whereas hyperthyroidism can cause an elevation of systolic blood pressure, leading to a widened pulse pressure.

Secondary hypertension has a positive outlook with treatment. Early detection and treatment can lower the risk of damage to your blood vessels and heart from ongoing high blood pressure. […] This means its possible for secondary hypertension to go away. Your blood pressure may return to normal once you treat the underlying cause. But its also possible for your blood pressure to remain higher than it should be. This might be because theres another cause. If this happens, you may need to take medicine to keep it in the healthy range.

Secondary hypertension is usually resistant to antihypertensive drugs if the underlying mechanism is not identified and treated appropriately. […] However, with early identification and treatment of the underlying cause, secondary hypertension has a favorable prognosis.
- #27 Diagnosis of Secondary Hypertension: An Age-Based Approach | AAFPhttps://www.aafp.org/pubs/afp/issues/2010/1215/p1471.html
Secondary hypertension is a type of hypertension with an underlying, potentially correctable cause. […] Approximately 5 to 10 percent of adults with hypertension have a secondary cause. […] Secondary hypertension also should be considered in patients with resistant hypertension, and early or late onset of hypertension. […] Whenever a patient is diagnosed with hypertension, one purpose of the initial assessment (i.e., history, physical examination, and basic laboratory testing) is to exclude possible secondary causes. […] Indications for further investigation into a possible secondary etiology in the absence of suggestive signs and symptoms include resistant hypertension (defined as elevated blood pressure despite patient adherence to optimal dosages of three antihypertensive agents, including a diuretic), early or late onset of hypertension, a severe or accelerated course, or specific drug intolerances.
- #28 Development of the prediction model for hypertension in patients with idiopathic inflammatory myopathieshttps://pmc.ncbi.nlm.nih.gov/articles/PMC8678666/
Cardiac involvement is an important cause of morbidity and mortality in patients with idiopathic inflammatory myopathies (IIMs). Hypertension, an important cardiovascular risk factor for the general population, has a crucial role in heart involvement. However, few studies have focused on the hypertension associated with IIMs. This study aimed to develop and assess the prediction model for incident hypertension in patients with IIMs. […] The nomogram showed that age 50 years, diabetes mellitus, high levels of TG and LDLC, positive ANA and nonsmokers were more likely to develop hypertension in IIMs patients. In addition, the Cindex of the nomogram and the internal validation was good, which indicated this predictive model had good discriminative ability and calibration. Meanwhile, the decision curve analysis revealed this nomogram had good clinical usefulness. Clinicians can use these features to assess the risk of hypertension in IIMs patients, and early preventive measures should be taken to reduce the incidence of hypertension in highrisk patients.

Background: Secondary hypertension is a kind of hypertension with a definite etiology and may be cured. Patients with suspected secondary hypertension can benefit from timely detection and treatment and, conversely, will have a higher risk of morbidity and mortality than those with primary hypertension. […] The ML prediction models in this study showed good performance in detecting 4 etiologies of patients with suspected secondary hypertension; thus, they may potentially facilitate clinical diagnosis decision making of secondary hypertension in an intelligent way. […] Based on the EMRs from Fuwai Hospital, we developed 5 prediction models with good performance for 4 etiologies of secondary hypertension using XGBoost. Validation of the composite outcome prediction model achieved an AUC of 0.924, while the 4 prediction models of the secondary hypertension etiologies achieved AUCs of 0.938-0.965 in the validation data set. The observed model performance suggested that it was feasible to derive effective ML prediction models of secondary hypertension, which may play important roles in predicting etiologies of patients with suspected secondary hypertension.

Secondary hypertension is a type of hypertension with an underlying and potentially reversible cause. It makes up only a small fraction (5% to 10%) of hypertensive cases. The prevalence of secondary hypertension varies by age and is more common in younger persons, with a prevalence close to 30% in those 18 to 40 years of age with hypertension. […] Secondary hypertension should be considered in the presence of suggestive signs and symptoms such as severe or resistant hypertension, onset before 30 years of age (especially before puberty), malignant or accelerated hypertension, and an acute rise in blood pressure from previously stable readings. […] Renovascular hypertension is a common, potentially reversible cause of secondary hypertension. Although it may contribute to only 1% of mild hypertension cases, it accounts for 10% to 45% of severe or malignant hypertension cases in white patients.

Several easily obtainable clinical and biochemical predictors, such as sex, systolic blood pressure, and serum potassium levels, could aid in identifying secondary causes of hypertension in young adult patients. […] The present study reported a prevalence of secondary causes of hypertension (3.4%), compared to other studies which reported a prevalence ranging from 2 to 8%. […] The key finding in this study was the identification of three easily obtainable clinical and biochemical factors that could predict secondary causes of hypertension in young hypertensive adults. […] While individuals lacking these predictors may be at a lower risk for secondary hypertension, these markers should be used alongside a comprehensive clinical evaluation and are not meant to serve as definitive diagnostic criteria. […] Therefore, primary aldosteronism should be considered in patients with severe hypertension.
