Herz-Syndrom (Nierenprobleme bei Herzerkrankungen)

The heart and kidneys depend on each other. When the heart pumps poorly, the kidneys receive less forward flow and, more importantly, are congested by back-pressure in the veins, so they filter less and hold on to salt and water. That extra fluid in turn strains the heart. Doctors call this cardiorenal syndrome.

Around half of people with heart failure have reduced kidney function, and kidney disease itself accelerates artery hardening, heart attacks and rhythm problems. Managing the two together is a balancing act, since several essential heart medicines alter kidney blood tests.

Symptome

• Breathlessness on exertion or when lying flat
• Swollen ankles, legs or abdomen and rapid weight gain
• Passing less urine despite diuretics
• Tiredness and poor appetite
• Dizziness or low blood pressure
• Rising creatinine or potassium on routine blood tests

Ursachen und Risikofaktoren

Acute worsening of heart failure, a heart attack or cardiac surgery can cause a sudden fall in kidney function. Chronic heart failure leads to slow decline through congestion, low output and hormonal activation. Shared risk factors, namely diabetes, hypertension, smoking and atherosclerosis, including renal artery narrowing, damage both organs. Contrast dye for angiography, over-diuresis, NSAIDs and low blood pressure add injury. In the other direction, chronic kidney disease causes fluid overload, anaemia, vessel calcification and thickened heart muscle.

Wie es diagnostiziert wird

• Creatinine, eGFR and electrolytes over time: The trend matters more than one value; a modest rise when starting heart drugs is often acceptable.
• Urine albumin to creatinine ratio: Indicates intrinsic kidney damage and cardiovascular risk.
• Natriuretic peptides (BNP or NT-proBNP): Help assess heart failure, though levels run higher in kidney disease.
• Echocardiogram: Measures pumping function, valve disease and filling pressures.
• Kidney ultrasound with Doppler: Looks at kidney size, obstruction and possible renal artery narrowing.
• Assessment of congestion: Clinical examination, weight, and sometimes lung or vein ultrasound to guide diuretic dosing.

Behandlungsmöglichkeiten

• Decongestion with diuretics: Loop diuretics, sometimes intravenous or combined with other types; relieving congestion often improves kidney function.
• Heart failure medicines that also protect kidneys: SGLT2 inhibitors, ACE inhibitors, ARBs or sacubitril-valsartan, and mineralocorticoid antagonists, adjusted carefully with potassium monitoring.
• Potassium binders: Allow protective drugs to be continued when potassium runs high.
• Treating anaemia and iron deficiency: Intravenous iron improves symptoms in heart failure.
• Devices and cardiac procedures: Resynchronisation pacemakers, valve repair or revascularisation when indicated, with kidney-protective planning around contrast.
• Ultrafiltration or dialysis: For fluid overload that no longer responds to diuretics; peritoneal dialysis is sometimes used for this purpose.

Wenn es dringend ist

Call emergency services locally for severe breathlessness at rest, chest pain, fainting, a sudden large weight gain with very little urine, or palpitations with known high potassium. Decompensated heart failure is not a condition to fly with.

Reisen nach Türkiye zur Behandlung

Day-to-day management relies on frequent weight, blood pressure and blood test adjustments by your own doctors. A visit can offer a joint cardiology and nephrology review of your medicines, echocardiography and kidney imaging, or a planned cardiac procedure with kidney precautions such as hydration and minimal contrast. You should be stable, not breathless at rest, and cleared to fly by your cardiologist.
